One of the unanswered questions in astronomy is just how supermassive black holes grew so big, so quickly. A team of astronomers have tried to answer this question by searching for actively feeding supermassive black holes (aka quasars) as a way to measure how much material material they are actually accumulating. They studied nebulae near the quasars that light up with the quasar is releasing radiation and found that many of the more distant quasars have only been active for a few hundred thousand years, not long enough to grow to the size we see today.

New technique for cell or drug delivery, localization of bioelectric materials, and wound healing uses ultrasound to activate printing within the body.

Kosmos 482, a Soviet spacecraft that never made it beyond Earth’s orbit on its way to Venus, is due to come crashing down on 9 or 10 May

Engineers developed a ping-pong-playing robot that quickly estimates the speed and trajectory of an incoming ball and precisely hits it to a desired location on the table.

Environmental engineers have developed critical methods to remove toxic selenium from water.

In space, energetic neutrinos are usually paired with energetic gamma rays. Galaxy NGC 1068, however, emits strong neutrinos and weak gamma rays, which presents a puzzle for scientists to solve. A new paper posits that helium nuclei collide with ultraviolet photons emitted by the galaxy's central region and fragment, releasing neutrons that subsequently decay into neutrinos without producing gamma rays. The finding offers insight into the extreme environment around the supermassive black holes at the center of galaxies like NGC 1068 and our own and enhances our understanding of the relationships between radiation and elementary particles that could lead to technological advances we haven't yet imagined.

Mercury is released by environmental and human-driven processes. And some forms, specifically methylmercury, are toxic to humans. Therefore, policies and regulations to limit mercury emissions have been implemented across the globe. And, according to new research, those efforts may be working. Researchers found that atmospheric mercury levels have decreased by almost 70% in the last 20 years, mainly because human-caused emissions have been reduced.

A new study analyzes the results of a randomized controlled trial (RCT) that showed that brick kiln owners in Bangladesh are willing and able to implement cleaner and more efficient business practices within their operations -- without legal enforcement -- if they receive the proper training and support, and if those changes are aligned with their profit motives. The study is the first to rigorously demonstrate successful strategies to improve efficiency within the traditional brick kiln industry.

Supermassive Black Holes reside at the center of large galaxies, where they dominate their surroundings and sometimes eat stars. When they gobble up a star, they emit a distinctive light flare. This makes it easier for astronomers to pinpoint their location. Astronomers have detected one of these flares offset from a galactic center. Is the black hole shifting its location?

Analysing the gene activity of every single bacterial cell in a colony? A new technique of single-cell transcriptomics developed in W rzburg can do this much more efficiently than other methods: It reliably detects 300 to 600 genes per bacterial cell with a high success rate of 95%, thereby surpassing the efficiency of established procedures.

Researchers have developed a more efficient chip as an antidote to the vast amounts of electricity consumed by large-language-model artificial intelligence applications like Gemini and GPT-4.

Researchers have developed cutting-edge MRI technology to diagnose a common heart problem more quickly and accurately than ever before. Aortic stenosis is a progressive and potentially fatal condition, affecting about five per cent of 65-year-olds in the US -- with increasing prevalence in advancing age. Symptoms include chest pains, a rapid fluttering heartbeat and feeling dizzy, short of breath and fatigued -- particularly with activity. The new study reveals how a four-dimensional flow (4D flow) MRI scan can diagnose aortic stenosis more reliably than current ultrasound techniques. The superior accuracy of the new test means doctors can better predict when patients will require surgery.

A research team has discovered a surprising phenomenon that could revolutionize how we think about signal amplification. Just two tiny vibrating units can, when connected with a delay, amplify their combined vibrations by 100 million times. Their findings have applications for communication technology, suggesting that small, simple devices could be used to transmit clear signals over long distances.
