Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping.

Research has achieved a breakthrough in eco-friendly display technology, creating highly efficient and stable blue quantum dot LEDs (QLEDs) that could power the next generation of televisions, smartphones, VR headsets and energy-efficient lighting -- without using toxic heavy metals.

A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers.

Cement manufacturing and repair could be significantly improved by using biocement-producing bacteria, but growing the microbes at construction sites remains a challenge. Now, researchers report a freeze-drying approach that preserves the bacteria, potentially allowing construction workers to ultimately use powder out of a packet to quickly make tiles, repair oil wells or strengthen the ground for makeshift roads or camps.

Antimalarial drug resistance is a pressing issue in combating the spread of malaria worldwide. In a new study, researchers discovered a key process where malarial parasites take up a human blood cell enzyme, which could provide a new approach for antimalarial treatment.

Walking into your favorite restaurant and seeing a robot chef in the kitchen may seem far-fetched, but new research suggests that bots could be a solution to persistent labor shortages in the industry.

Injuries to the articular cartilage in different joints, including the knee, are painful and limit mobility. Therefore, researchers are developing cartilage implants using cells from the patient's nasal septum. A recent study shows that giving these cartilage implants more time to mature significantly improved clinical efficacy, even in patients with complex cartilage injuries. This suggests that the method could also be suitable for the treatment of degenerated cartilage in osteoarthritis.

Engineers devised a new method for designing metals and alloys that can withstand extreme impacts, which could lead to the development of automobiles, aircraft and armor that can better endure high-speed impacts, extreme heat and stress.

Engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging or mishandling whatever it holds.

Whether it's rivers cutting through earth, lava melting through rock, or water slicing through ice, channels all twist and bend in a seemingly similar back-and-forth manner. But a new study has discovered that channels carved by rivers actually have curves distinct to those cut by lava or ice.

Engineers have developed a method to utilize aluminum to improve performance of water electrolysis catalyst.

Experts see peer recognition as important to student success in physics, and a new study gives college-level physics instructors insight into how students perceive the message from their classmates that 'you're good at physics.' Even when women receive similar amounts of recognition from peers as men for excelling in physics classes, they perceive significantly less peer recognition, the researchers found.

A newly developed pentanuclear iron complex can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex, researchers have obtained a polymer-based catalyst, poly-Fe5-PCz, and achieved water oxidation with up to 99% Faradaic efficiency and exceptional stability, even under rigorous conditions. This breakthrough offers a scalable alternative to rare metal catalysts, advancing hydrogen production and energy storage for renewable energy.

Concrete structures in Japan capture and store about 14% of the CO2 emissions released during cement production, according to a new study. Their findings provide crucial insights for offsetting CO2 emissions from cement production, which is responsible for approximately 8% of global carbon emissions.

Working at nanoscale dimensions, billionths of a meter in size, a team of scientists revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.

Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are removed along with the nodules, and on the adjacent seafloor, where the sediment suspended by the mining resettles.

Theoretical physicists reveal that room-temperature superconductivity is possible within the laws of our Universe, linked to fundamental constants like electron mass and Planck constant. Discovery could revolutionize energy, quantum computing, and medical tech by enabling superconductors to work at ambient conditions. Research explores how varying fundamental constants could alter superconductivity limits, offering a glimpse into the delicate balance of our Universe.

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers presents a novel machine learning method that can analyze gravitational waves emitted by neutron star collisions almost instantaneously -- even before the merger is fully observed. A neural network processes the data and enables a fast search for visible light and other electromagnetic signals emitted during the collisions. This new method could be instrumental in preparing the field for the next generation of observatories.

Scientists encased nanodiamonds in tiny moving droplets of water to improve quantum sensing. The new technique lets researchers detect trace amounts of certain ions and molecules, and could someday find applications in environmental monitoring, medicine, bioengineering, and more.

Researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop to chip-based systems.
