Surpassing the lower limit on computing energy consumption

Researchers have found that using topological insulators in transistors could reduce switching energy by half and the overall energy used by each transistor by a factor of four. This breakthrough could lead to substantial reductions in computing energy consumption, as the industry continues to strive for sustainable technologies.

Sleep disorders and surgery: Anesthesia & Analgesia marks first decade of the Society of Anesthesia and Sleep Medicine

The Society of Anesthesia and Sleep Medicine celebrates its first decade of research achievements in the common ground between sleep and anesthesia. Studies examine the outcomes of patients with undiagnosed sleep disorders or breathing issues undergoing surgery, highlighting the potential for treating perioperative periods as opportuni...

Where's my horse-sized rabbit?

A research team at Kyoto University investigated the fossil record and evolutionary history of lagomorphs to answer why they don't rival horse sizes. They found that larger herbivore competitors and energetic disadvantage hindered their growth, with body sizes of ungulates being a key predictor.

Single metasurface for simultaneous detection of SAM and OAM

A team of scientists has developed a single spin-decoupled metasurface that can distinguish between spatial angular moment (SAM) and orbital angular momentum (OAM) modes. The device exploits the geometric phase and dynamic phase to transform vortex beams into focusing patterns, enabling simultaneous detection of SAM and OAM.

NUS researchers discover protein that causes neurological complications in HFMD

Researchers at NUS have identified two new proteins that contribute to EV-A71's ability to invade the central nervous system, making them potential targets for treating severe HFMD cases. This discovery could lead to the development of more effective treatments, particularly for young children affected by this illness.

UK waters are home again to the bluefin tuna

Atlantic bluefin tuna numbers appear to be increasing in UK waters after a long period of decline. Researchers have documented this growth using data from citizen scientists, eco-tourism vessels, and fisheries records, revealing that these fish arrive in May and stay until January, with peak sightings between August and October each year.

Racial violence and the mental health of Black Americans

A new study analyzes the impact of highly publicized acts of racial violence on the mental health of Black Americans. Research suggests that experiencing racism, even vicariously, can harm mental and physical health, and that highly publicized anti-Black violence is strongly associated with poor mental health days among Black respondents.

Scientists find Galapagos volcano could help forecast future eruptions

Researchers have gained new insights into volcanic behavior and can now track unrest before eruptions, enabling early warnings for local authorities and the public. The study provides a detailed description of Sierra Negra's 2018 eruption, capturing its inflation, fracture, and caldera resurgence.

Fast radio bursts shown to include lower frequency radio waves than previously detected

A team of researchers from McGill University has made a groundbreaking discovery about fast radio bursts (FRBs), revealing that they include lower frequency radio waves than previously detected. The study used the combined capacities of two radio telescopes, CHIME and LOFAR, to detect FRBs at frequencies as low as 110 MHz, shedding new...
