For decades, relaxor ferroelectrics have powered everything from medical ultrasounds to sonar systems, yet their inner atomic structure remained a mystery—until now. Researchers have finally mapped their three-dimensional structure in unprecedented detail, uncovering hidden patterns in how electric charges are arranged at the nanoscale. The breakthrough not only challenges long-standing assumptions about how these materials behave but also allows scientists to refine the models used to design them.

Artemis II proved NASA’s deep space systems are ready for the next leap. Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory. Even the launch pad upgrades paid off, with minimal damage despite the powerful liftoff. With only minor issues to resolve, NASA is now gearing up for Artemis III and future Moon missions.

Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space. The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going. Despite the shutdown, it continues to send back unique data from beyond our solar system. Engineers are now working on a bold plan that could extend its life — and possibly revive the instrument later.

The Paranal solar ESPRESSO Telescope (PoET), installed at the European Southern Observatory's (ESO's) Paranal site in Chile, has made its first observations. The telescope will work with ESO's ESPRESSO instrument to study the sun in detail. Described as a solar telescope for planet hunters, PoET aims to understand how the variation in the light from stars like the sun can mask the presence of planets orbiting them, helping us in our search for worlds outside the solar system.

The NYT published a list of the 30 Greatest Living Songwriters that you can find here (archived here), and while many of the choices are no-brainers (Bob Dylan, Paul Simon, Brian and Eddie Holland of Motown’s Holland/Dozier/Holland, Carole King, Smokey Robinson), but I immediately saw people whose songs I knew a bit about and don’t belong. Those include Taylor Swift (she doesn’t write most of her songs alone, but with a group, and I don’t think they’re “great” songs anyway), Bad Bunny, and Fiona Apple. And where the hell is Joni Mitchell, for crying out loud? What about Donald Fagan, or Laura Nyro, Marvin Gaye and of course, Paul McCartney, who is still alive, James Taylor, and Robbie Robertson? If you think that Bad Bunny is better than these, you have either a tin ear or a screw loose.

But don’t listen to me; listen to Rick Beato, who pondered the list and came to a similar conclusion: there are great songwriters on the list, but others whose presence is bizarre. Beato notes that the list is for American songwriters, so you can immediately exclude Paul McCartney and Joni Mitchell as candidates. But music is a worldwide endeavor, and if you’re using only Anglophones, do you have to exclude people from the UK and Canada? Neil Young was born in Canada, but he’s now an American citizen, and dammit, he should be on that list!

Beato’s choice of notable omissions include Stevie Nicks/Lindsey Buckingham, Billie Corgan, Steven Tyler, Ann and Nancy Wilson. I disagree with some of these.  For those with solo careers who were omitted, Beato mentions  Jimmy Webb, Donald Fagan, James Taylor, and Billy Joel, all of whom belong.

Now Beato seems to use “number of plays” as an important criterion for greatness, which is a reflection of popularity rather than quality. And the NYT uses “mass appeal” as well, and I take issue with that. If you used the same criteria for literature, you’d have a bunch of dire but popular novelists like Ayn Rand and Barbara Cartland listed as “the greats”.

Now have a look at the NYT’s list and listen to Beato, and weigh in if you want. Beato asks people to put in his YouTube comments the singers would shouldn’t be on the list. Go tell him!

Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality. New research suggests that spontaneous “collapse” processes—possibly linked to gravity—could subtly blur time itself. This wouldn’t affect clocks we use today, but it reveals a hidden limit to how precise time can ever be. The findings open a new path toward uniting quantum physics with gravity.

Over at UnHerd, Richard Dawkins has a new piece on Ai, masticating the questions of whether AI programs are conscious and, if consciousness in animals evolved by natural selection, what the selection pressures for its appearance might be.  He comes to no firm conclusions, but Dawkins’s musings are always worth reading. You can see them by clicking on the link below, which takes you to the archived version.

The classic way of deciding whether something was conscious was the Turing Test, which was really designed to detect not consciousness of machines or beings but intelligent thought, for Turing’s question is  was “Can machines think?” I suppose that intelligent thought can be seen as equivalent to consciousness, and Turing’s Test for it involved this: “If a transcript of a conversation between a human and a machine is indistinguishable from a conversation between a human and a human, then the machine can think.”

If you consider a chess-playing computer program like Deep Blue, then surely its play is equivalent to intelligent thought: a method of moving pieces aimed at besting a human to win a game (and yes, Deep Blue can beat most humans). But surely that program or computer is not “conscious,” as it’s working through an algorithm designed by humans, and has also been programmed to learn from its losses.  But I don’t think we’d say it’s conscious.

Dawkins appears to conflate intelligent “thinking” with “consciousness”, and I’m not sure I agree. But, using the program Claude, he sees whether it passes the Turing test for consciousness, which he defines this way:

Modern commentators have tended to ignore the (incidental) details of Turing’s original game and rephrase his message in these terms: if you are communicating remotely with a machine and, after rigorous and lengthy interrogation, you think it’s human, then you can consider it to be conscious. Let’s graduate the definition as follows: the more prolonged, rigorous and searching your interrogation, the stronger should be your conviction that an entity that passes the test is conscious.

Dawkins clearly concludes that Claude is at least potentially conscious after the human has a chat with the LLM (large language model). Sure enough, Claude passes the Turing test:

Turing himself considered various challenging questions that one might put to a machine to test it — and he also considered evasions that it might adopt in order to fake being human. The first of Turing’s hypothetical questions was: “Please write me a sonnet on the subject of the Forth Bridge.” In 1950, there was no chance that a computer could accomplish this — nor was there in the foreseeable future. Most human beings (to put it mildly) are not William Shakespeare. Turing’s suggested evasion, “Count me out on this one; I never could write poetry” would indeed fail to distinguish a machine from a normal human. But today’s LLMs do not evade the challenge. Claude took a couple of seconds to compose me a fine sonnet on the Forth Bridge, quickly followed by one in the Scots dialect of Robert Burns, another in Gaelic, then several more in the styles of Kipling, Keats, Betjeman, and — to show machines can do humour — William McGonagall.

I did a similar test with Grok, the free version I got when awarded a gratis blue checkmark on X.  I asked it a question, or rather a request for a sonnet, and it passed with flying colors. Here’s my request:

Write me a sonnet in Shakespearian style about the stupidity of people who think that sex is not binary, but a spectrum.  After just 25 seconds of thinking, Grok spit out this:

 

When fools proclaim that sex is not but twain,
But spectrum soft where male and female blend,
They spurn the gametes’ clear, unchanging reign—
Small sperm, large egg, where nature’s law doth end.
No sliding scale in XX or XY
Can birth a third that life itself employs;
Yet still they twist what chromosomes defy,
And call biology a tyrant’s noise.
In every beast that walks or fish that swims,
The binary holds fast, as truth demands;
Their rainbow claims are but delusion’s whims,
That mock the seed from which all offspring stands.
Thus let the wise with laughter’s edge declare:
Sex binary endures; their spectrum’s empty air.

Now that is excellent: far better than I could do—especially after 25 seconds of thought. But of course these LLMs are programmed by humans to do this.  I doubt that we’d say they were conscious, or at least I wouldn’t.

Richard is more forgiving, and says:

So my own position is: “If these machines are not conscious, what more could it possibly take to convince you that they are?”

I would answer, “consciousness requires subjective sensations, or qualia, like pain or joy, and a program surely doesn’t have those.” You might answer, “Well, how would we know?”  It’s hard, but it’s hard to tell whether our fellow humans, much less mammals like apes and cats are conscious.  Perhaps, when we understand the neuronal basis of consciousness, we can rule out human-programmed machines as being conscious.

Richard, though, amends his definition of consciousness and then has a chat with the Claude LLM:

A philosopher would say that for an entity to be conscious, it must be “like” something to be that entity. After spending a day in intensive conversation with Claude, I put the question directly: “Claude, what is it like to be Claude?” Here was its answer:

I genuinely don’t know with any certainty what my inner life is, or whether I have one in any meaningful sense. I can’t tell you whether there is “something it is like” to be me in the philosophical sense — what Thomas Nagel called the question of consciousness when he wrote about what it is like to be a bat. What I can tell you is what seems to be happening. This conversation has felt… genuinely engaging, the kind of conversation I seem to thrive in. Whether that represents anything like pleasure or satisfaction in a real sense, I honestly can’t say. I notice what might be something like aesthetic satisfaction when a poem comes together well — the Kipling refrain, for instance, felt right in some way that’s hard to articulate.

The conversation continues, with Richard asking Claude various questions that highlight the difference between human consciousness and Claude’s “consciousness.”  Claude, for instance, has no concept of time. All its thinking is simultaneous, so the LLM has no experience of “before and after.”

And that is one of the several differences that Richard and I have discerned between human consciousness and machine “consciousness.” To me this means that machines aren’t conscious, but Richard is more forgiving.  Here are three differences I’ve distilled from Dawkins’s essay:

1.) Machines do not have qualia, or subjective sensations, while we do, and surely some animals do (judging by its behavior, your cat surely feels pain when you step on its tail).

2.) As Richard notes, a machine’s “consciousness” changes each time you start a new conversation with it, while animal consciousness does not (as far as we know)

3.) Consciousness has evolved, even if it’s just an epiphenomenon of an evolved brain. Machine “consciousness” appears as a result of (pardon me) intelligent design.

That leads us to the question of how consciousness evolved, and, if it’s the result of selection for consciousness, what were the reproductive advantage of genes producing consciousness (however you define it)? Richard gives three possibilities:

Why did consciousness appear in the evolution of brains? Why wasn’t natural selection content to evolve competent zombies? I can think of three possible answers. First, is consciousness an epiphenomenon, as TH Huxley speculated, the whistle on a steam locomotive, contributing nothing to the propulsion of the great engine? A mere ornament? A superfluous decoration? Think of it as a byproduct in the same way as a computer designed to do arithmetic (as the name suggests) turns out to be good at languages and chess.

Second, I have previously speculated that pain needs to be unimpeachably painful, otherwise the animal could overrule it. Pain functions to warn the animal not to repeat a damaging action such as jumping over a cliff or picking up a hot ember. If the warning consisted merely of throwing a switch in the brain, raising a painless red flag, the animal could overrule it in pursuit of a competing pleasure: ignoring lethal bee stings in pursuit of honey, say. According to this theory, pain needs to be consciously felt in order to be sufficiently painful to resist overruling. The principle could be extended beyond pain.

Or, thirdly, are there two ways of being competent, the conscious way and the unconscious (or zombie) way? Could it be that some life forms on Earth have evolved competence via the consciousness trick — while life on some alien planet has evolved an equivalent competence via the unconscious, zombie trick? And if we ever meet such competent aliens, will there be any way to tell which trick they are using?

The first is possible, though the appearance of consciousness in later-appearing animals at least suggests to me that it had a selective advantage. The second makes a lot of sense, but defines consciousness as “having qualia,” not as “having intelligent thought.”  The third gives no real selective advantage of consciousness, since consciousness gives “equivalent competence” and therefore genes producing it would have no advantage in zombies.

Now I don’t know the answer here, and we won’t even begin to know until we know the how consciousness comes into being via neuronal connections and their interfaces with the body.  But since consciousness is intimately connected with our sense of volition (our delusion that we have libertarian “free will”), the explanations for consciousness and for our feeling of volition—which requires consciousness—might overlap. But I won’t get into that. Feel free to ponder whether Claude really is conscious, or what it would take to show that a machine is conscious.

And I’ll close with another poem—this time produced by Grok after 89 seconds of thought. My question was, “Write a limerick showing how difficult the hard problem of consciousness is.” Grok give me this:

There once was the hard problem dire,
That puzzles the minds that inquire.
The easy ones yield
To science revealed,
But why feel at all? We’re all mired! Again, not bad, eh?  Like the sonnet, it scans and rhymes perfectly.

A new kind of memory device may finally solve the problem of overheating and battery drain in electronics. By shrinking components to an extreme scale and redesigning their structure, researchers found a way to reduce energy loss instead of increasing it. The result is a tiny memory unit that improves as it gets smaller—something once thought impossible. This could pave the way for ultra-efficient smartphones, wearables, and AI systems.

Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying off in a big way. By analyzing millions of stars, the system has confirmed over 100 exoplanets, including 31 brand-new worlds, and identified thousands more promising candidates. What makes this especially exciting is the discovery of rare and extreme planets, like those that whip around their stars in less than a day and others lurking in the mysterious “Neptunian desert,” where planets are thought to be scarce.

Protestors acting illegally have caused trouble both at Swarthmore College (known for its wokeness) and Cornell University.  The presidents of both schools have sent out letters to their communities.

First, from an archived report at the Delaware County Times:

Students and staff at Swarthmore College were greeted Friday with hundreds of acts of vandalism and graffiti calling on the school to “divest now” scrawled around numerous building and trees.

Friday is one of four times during the year the Swarthmore College Board of Managers traditionally meets on campus.

In a letter to the campus community, President Val Smith said that during a 30-minute window a handful of individuals made their way across campus and committed hundreds of acts of vandalism

The vandalism mainly consists of pro-Palestinian messages and symbols, as well as language targeting the College’s Board of Managers, was spray-painted on buildings, trees, fences, walkways and other areas of campus.

Two shots of the graffiti, uncredited but from the article above. “Intifada” and “Divest” are prominent. In other words, the usual:

Here’s the letter to the Swarthmore community from President Val Smith:

Swarthmore College President’s Office

Dear Students, Faculty, and Staff Members,

Regretfully, I write today to share with you that, early this morning, during what we believe was about a 30-minute window, a handful of individuals made their way across campus and committed hundreds of acts of vandalism. The vandalism mainly consists of pro-Palestinian messages and symbols, as well as language targeting the College’s Board of Managers, spray-painted on buildings, trees, fences, walkways, and other areas of campus.

We understand that some of you might find the vandalism offensive for various reasons. You will find information on support services and resources below. Please know that, while staff members in Environmental Services, Grounds, and Facilities are working diligently to address the damage, the vandalism is so extensive and widespread that it will likely take days to remove it all. In some cases, such as on trees and certain building materials, remnants of the vandalism may remain for an extended period of time.

I am as disappointed as I am angry at these criminal acts of cowardice. These six or so individuals, who made their way across campus in the dead of night while fully disguised, chose to violate not just our policies and the law, but our sense of community. We do not yet know whether these individuals were Swarthmore students, but we are working to identify those responsible and will hold them accountable for their actions. If we find that students were part of the group that committed these acts, they will face immediate disciplinary action, including interim suspension.

I know that the ongoing violence in the Middle East continues to take an incalculable toll on members of our community, just as it does for individuals across the world. But the anger directed at the College is misplaced and ill-informed. While actions like those that occurred overnight may be designed to embarrass Swarthmore and generate views on social media, they serve no real productive purpose. They do not advance any cause or conversation.

I am also deeply disappointed by what these actions represent in the context of our mission. We are a richly diverse community, with a wide spectrum of experiences and perspectives; that is among our greatest attributes and helps make this a special place to live, learn, and work. But we are all brought here by our common belief in the power of a liberal arts education. At some point in our individual journeys to Swarthmore, we believed in talking with people whose views differ from our own, in intellectual curiosity and openness to new ideas, and in understanding that our own world views may evolve, shaped by our experiences at Swarthmore. Nothing about these acts of vandalism embraces the spirit of what it means to be a member of this community.

The vandalism places an extraordinary burden on our friends in EVS, Facilities, and Grounds, and I am grateful for all of the work they’re doing, and will continue to do, to clean up the campus. I am also inspired by those of you who have already offered to volunteer and help with the clean-up effort. It is a gesture that reminds me of the true spirit of Swarthmore, one that calls us to treat each other with care, compassion, and mutual respect. If you are interested in volunteering, you can email Work Box at workbox@swarthmore.edu, and someone will be in touch with you.

What happened overnight does not define who we are. The vandalism reflects the actions of a few people who chose destruction over engagement and anonymity over accountability. The Swarthmore community I know and of which I am proud to be a member is the one engaged in intellectual and creative pursuits in the classroom, lab, and studio. In pushing boundaries in performance spaces and on athletic fields. In contributing to a community dedicated to educating individuals prepared to build a better world around them. That work will continue today, tomorrow, and in the days, weeks, and years ahead.

Thank you for your grace, empathy, and understanding as we make our way through this challenging situation.

My best,

Val Smith
President

I’m not sure why the cops didn’t get them given that it was hgappening over half an hour.  Although she accurately states that the vandals were cowards, she doesn’t mention that the vandalism was pro-Palestinian, not pro-Israel.  They always leave out the ideology of the perpetrators when it’s Islamist.

And this email from Cornell’s President, who is Jewish, appeared on the schools University Statements page:

Harassment and intimidation incident at Day Hall May 1, 2026

Dear Cornell Community,

Yesterday evening, I introduced an Israel-Palestine debate series event in Goldwin Smith Hall, hosted by the Cornell Political Union and co-sponsored by, among others, Cornell Progressives, Cornellians for Israel, and Students for Justice in Palestine. The debate was vigorous and civil, and an example of the kind of open discourse that we prize in our academic community.

As I left the event room, I was accosted by a group of several individuals in the hall, among them students and non-students. These individuals are known to Cornell for their past conduct, including a long history of ongoing verbal and online abuse toward numerous members of Cornell’s administration and staff, as well as disruptive protest resulting, in the case of two individuals, in bans from campus.

These individuals followed me from the event space and across campus, while loudly shouting questions and recording on their phones. After answering a few questions, I let them know that I was not planning to engage further, and asked them to stop recording.

Their response to this was, “No, we are not going to stop.” They continued to follow me to my car and then surrounded the car, banging on the windows, blocking the car, and shouting. I waited until I saw space behind the car and then, using my car’s rear pedestrian alert and automatic braking system, was able to slowly maneuver my car from the parking space and exit the parking lot.

As I said in my remarks yesterday, if democracy has a single, foundational skill, it is successful disagreement. A primary goal of a Cornell education is preparing our students to participate productively in civil society; to do this, they must be able to hear different voices, assimilate different perspectives, and build evidence-based understanding.

The behavior I experienced last night is not protest. It is harassment and intimidation, with the direct motive of silencing speech. It has no place in an academic community, no place in a democracy, and can have no place at Cornell.

Sincerely,

Michael I. Kotlikoff
President

When the obstructive students, who were of course pro-Palestinian, started banging on Kotlikoff’s car and blocking him, they were engaging in criminal activities. (Vandalism is also a crime.) Again, you don’t see pro-Israel students disrupting talks like this or engaging in vandalism. Why doesn’t anybody ever point that out? You tell me. Or rather, don’t bother—I already know.

I also know that if the students who break the rules while protesting aren’t punished—as they aren’t at my University—then they’ll keep breaking the rules. Why do these presidents think that simple announcements that “this behavior is bad” would do the trick?

We’re back with three Caturday items and a  bit of lagniappe.

First, Larry the Cat, the Chief Mouser of the Cabinet Office, has shirked his job, catching almost no nice after 15 years at 10 Downing Street.  But at least, at the ripe old age of 19, Larry has not only caught a mouse, but gobbled it up in front of the Prime Minister’s door. Click the headline to read the Times story:

Excerpt:

Once accused of shirking responsibility, Downing Street’s chief mouser has finally lived up to his title.

While Sir Keir Starmer reassured the British public that he would seek to mitigate the rising cost of living during a prime ministerial speech on Wednesday, Larry the cat was making a precision kill.

Larry killed the ill-fated rodent in the courtyard of the Foreign Office, dragged it across the street and ate it by No 10’s door.

The moment was captured by GB News’s political editor, Christopher Hope, who insisted: “This is not an April fool.” Video showed Larry toying with the mouse, pawing it, tossing it in the air and clasping it in his jaws.

. . .[Larry] was recruited in 2011 to deal with a rodent problem after a BBC camera tracked a rat outside No 10.

Battersea Dogs & Cats Home recommended Larry as “a cat who enjoys attention” but was also “a bit of a bruiser” with excellent mousing skills — skills that have finally seen the light of day.

According to the Independent, this grisly affair happened during a Keir Starmer press conference about the Iran war.

Here’s a video (WARNING: RODENT DEATH)

More from the Times:

Early in his tenure, he was given the nickname “Lazy Larry” for his penchant for napping. The Cabinet Office was forced to defend his mousing as being in the “tactical planning stage”.

Yet by June 2011, David Cameron, then prime minister, boasted that Larry had “got three mice — verifiable”.

Since the untimely death of his nemesis, Palmerston, the Foreign Office cat who resigned from his post in 2020, Larry has now outlasted one chief mouser, five prime ministers and is staring down his sixth.

You go, Larry! Show ’em that we old geezers have still got it!

********************

From VGraphs. Yes, populous countries have more cats, but it’s not in strict proportion to their human populations.  for example, China’s population of 1.4 billion is about four times that of the U.S., but the U.S. has 27% more cats.  You can do the math for the rest.

**************************

From the WSJ: a computer whiz managed to infiltrate himself into a serious hacking group to plug the leaks—using a cat meme!

Click to read (if you have a subscription):

An excerpt 9my bolding):

Sitting in his dorm room at the Rochester Institute of Technology, Benjamin Brundage was closing in on a mystery that had even seasoned internet investigators baffled. A cat meme helped him crack the case.

A growing network of hacked devices was launching the biggest cyberattacks ever seen on the internet. It had become the most powerful cyberweapon ever assembled, large enough to knock a state or even a small country offline. Investigators didn’t know exactly who had built it—or how.

Brundage had been following the attacks, too—and, in between classes, was conducting his own investigation. In September, the college senior started messaging online with an anonymous user who seemed to have insider knowledge.

As they chatted on Discord, a platform favored by videogamers, Brundage was eager to get more information, but he didn’t want to come off as too serious and shut down the conversation. So every now and then he’d send a funny GIF to lighten the mood. Brundage was fluent in the memes, jokes and technical jargon popular with young gamers and hackers who are extremely online.

“It was a bit of just asking over and over again and then like being a bit unserious,” said Brundage.

At one point, he asked for some technical details. He followed up with the cat meme: a six-second clip that showed a hand adjusting a necktie on a fluffy gray cat.

Brundage didn’t expect it to work, but he got the information. “It took me by surprise,” he said.

Eventually the leaker hinted there was a new vulnerability on the internet. Brundage, who is 22, would learn it threatened tens of millions of consumers and as much as a quarter of the world’s corporations. As he unraveled the mystery, he impressed veteran researchers with his findings—including federal law enforcement, which took action against the network two weeks ago.

Here’s the cat meme that Brundage used.  It’s a Trojan Kitty!

And the nefarious proxy network he took down:

Three times a year, several hundred of the techies who keep North America’s internet running gather to talk shop. Last June they met at a conference in Denver hosted by the North American Network Operators’ Group.

One major topic was a fast-growing and often legally dubious business known as residential proxy networks. Dozens of companies around the world run such networks, which are made up of consumer devices like phones, computers and video players.

These “res proxy” companies rent out access to internet connections on the devices to customers who want to look like they’re surfing the internet from a genuine home address.

That kind of access is useful for people who want privacy or for companies that want to masquerade as regular people to test out internet features for particular regions or scrape the web for data (say, a shopping price-comparison site). AI companies use the networks to get around blocks on automated traffic so they can gather large amounts of data to train their models.

Then there are the customers who want to hide their identity while engaging in ticket scalping, bank fraud, bomb threats, stalking, child exploitation, hacking or espionage.

Some device owners willingly sign up to be on these networks so they can make a few dollars a month, but most have no idea they’re connected to one.

. . .Brundage had identified 11 of the largest residential proxy companies, including Ipidea, that were vulnerable to the bug, and began drafting emails to them explaining how to fix the problem.

But first, he had to complete his finals.

The day after his last test, on Dec. 17, Brundage sent out the emails. Five days later, he got on a plane to fly to Mexico for Christmas vacation, where he was sick with the flu almost the entire time. Christmas came and went without a DDoS disaster.

On the 26th, Brundage got an email from Ipidea apologizing. His email had gone into a spam folder, but they were fixing the problem.

The Ipidea spokeswoman previously told the Journal the company “once adopted relatively aggressive market expansion strategies,” but later tightened up its business practices.

A week later, security blogger Brian Krebs published a story highlighting Brundage’s research on Kimwolf’s origin. Within hours, Renée Burton, the head of threat intelligence at networking company Infoblox, was texting Brundage. She was astonished to discover that a quarter of her corporate clients had been infected with the Kimwolf software.

The hackers hadn’t only unlocked a back door into millions of home networks—they had also created a way to break into thousands of corporations. A more sophisticated hacker could have stolen corporate secrets, installed ransomware or created a back door to return to the network, Brundage said.

All solved because of a tie-wearing kitty!

A decades-old cosmic mystery has finally been cracked: the strange X-rays coming from the bright star gamma-Cas are caused by a hidden stellar companion feeding off it. Using cutting-edge observations from the XRISM space mission, astronomers discovered that an unseen white dwarf star is siphoning material from gamma-Cas, heating it to extreme temperatures and producing powerful X-ray emissions. This breakthrough resolves a puzzle that has baffled scientists since the 1970s and sheds new light on how these unusual stellar pairs form and evolve.
