The James Webb Space Telescope has spotted six likely rogue worlds -- objects with planet-like masses but untethered from any star's gravity -- including the lightest ever identified with a dusty disk around it. The elusive objects offer new evidence that the same cosmic processes that give birth to stars may also play a common role in making objects only slightly bigger than Jupiter. Read more ›

While meant to simulate wood bats, regulation USA Baseball metal bats are more forgiving than wood for young players who might not connect with the ball on a bat's optimal 'sweet spot.' After testing wood bats and two types of metal bats with youth players, researchers found that the exit speed of a hit ball was as much as 5% faster with metal bats over wood. Analyzing the data, they... Read more ›

Researchers have developed an artificial intelligence which can differentiate cancer cells from normal cells, as well as detect the very early stages of viral infection inside cells. The findings pave the way for improved diagnostic techniques and new monitoring strategies for disease. The AI can detect rearrangements inside cells as small as 20nm, or 5,000 times smaller than the width of a human hair. These alterations are too small and... Read more ›

Neuroscientists have sought to better understand brain function but lacked the capability to observe neuronal activity deep within the brain. Scientists have applied rational molecular engineering to develop photoacoustic probes that can be used deep within brain tissue to label and visualize neurons. This imaging approach expands significantly on what neuroscientists have been able to see with conventional light microscopy, offering the potential to report on deep neuron activity and...

Scientists have analyzed crop yields of more than 1,500 fields on six continents, and found that production worldwide of important, nutritionally dense foods such as fruits, vegetables, nuts and legumes is being limited by a lack of pollinators. Read more ›

As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years according to Moore's law. Molecular electronics -- the use of single molecules as the building blocks for electronic components -- offers a potential pathway for the continued miniaturization of small-scale electronic devices. Devices that utilize molecular electronics require precise control over... Read more ›

Fighting cancer effectively often involves stopping cancer cells from multiplying, which requires understanding proteins that the cells rely on to survive. Protein profiling plays a critical role in this process by helping researchers identify proteins -- and their specific parts -- that future drugs should target. But when used on their own, past approaches haven't been detailed enough to spotlight all potential protein targets, leading to some being missed. Now,... Read more ›

New methods to shape RNA molecules into circles could lead to more effective and long-lasting therapies, shows a new study. The advance holds promise for a range of diseases, offering a more enduring alternative to existing RNA therapies, which often suffer from short-lived effectiveness in the body. Read more ›

Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucose or glycerol. By engineering photosynthetic cyanobacteria to live symbiotically inside yeast cells, the bacteria-yeast hybrids can produce important hydrocarbons, paving new biotechnical pathways to non-petroleum-based energy, other synthetic biology applicatio Read more ›

A new study finds more than half of adults surveyed worldwide expect to be seriously harmed by their water within the next two years. The study sought to understand public perceptions of drinking water safety. Because perceptions shape attitudes and behaviors, distrust in water quality has a negative impact on people's health, nutrition, psychological and economic well-being -- even when the water meets safety standards.

A quantum mechanical trick called 'spin squeezing' is widely recognized to hold promise for supercharging the capabilities of the world's most precise quantum sensors, but it's been notoriously difficult to achieve. In new research, physicists describe how they've put spin squeezing within better reach. Read more ›

Simulating particles is a relatively simple task when those particles are spherical. In the real world, however, most particles are not perfect spheres but take on irregular and varying shapes and sizes. Simulating these particles becomes a much more challenging and time-consuming task. Read more ›

A new, biomass-based material can be used to repeatedly capture and release carbon dioxide. The material is primarily made from lignin, an organic molecule that is a main component of wood and other plants, and it can take up carbon dioxide (CO2) from concentrated sources or directly from the air.
