For years, scientists have explored ways to alter the cells of microorganisms in efforts to improve how many products are made, including medicines, fuels, and even beer. But altering the genetic and regulatory processes that take place within cells presents challenges. Now bioengineers is working with a team of researchers to engineer microbial consortia, wherein cell subpopulations are...

The enormous black hole at the center of our galaxy is having an unusually large meal, and researchers don't know why. 'We have never seen anything like this in the 24 years we have studied the supermassive black hole,' said a professor of physics and astronomy.

Do data privacy concerns disproportionately affect people who access the internet primarily through cell phones? New research indicates that cell-mostly internet users are more likely to be exploited online, be victims of data leaks, have less knowledge of phone security practices, and have attitudes of resignation with regard to their agency over their data.

An observational study including 3.9 million cancer cases in seven high-income countries between 1995-2014 finds that survival of seven cancers is generally improving, although the overall level and pace of improvement varies between countries and for each cancer type.

A new gene therapy turns glial cells -- abundant support cells in the brain -- into neurons, repairing damage that results from stroke and significantly improving motor function in mice.

The theoretical model that astrophysicists have used for 40 years to determine the behavior and future of the sun is broken. It seems fixable, however, with information from experiments at Sandia's Z machine, done at the temperature of the sun, that can accurately determine how much energy the sun's components allow to pass through them.

A new synthetic material that creates a linked sensory network similar to a biological nervous system could enable soft robots to sense how they interact with their environment and adjust their actions accordingly.

Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a new study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.

This novel drone-based chemical monitoring system tracks the health of the Amazon in the face of global climate change and human-caused deforestation and burning.

As plants expand into new open habitats, geographical and climatic factors may matter more than species-specific traits, according to a new study.

By studying nearly five decades of data on more than 5,800 saguaros dotting Tumamoc Hill, researchers found that small variations in the hill's topography might buffer saguaro populations from the impacts of climate change.

Scientists set out to better understand how and when positive direct reciprocity -- paying back a kindness to a specific individual -- develops in young children. The findings suggest that for children, retribution comes before gratitude.

Researchers have published a comprehensive list of the types and ratios of microbes that inhabit the healthy human gut.

The muscles in bats' wings are much cooler than the muscles in their core, a new study finds -- and this research could one day enhance our understanding of human muscle.

The hoary bat, the species of bat most frequently found dead at wind power facilities, is declining at a rate that threatens its long-term future in the Pacific Northwest, according to a novel and comprehensive research collaboration.

An in-depth analysis of the skull biomechanics of a giant extinct kangaroo demonstrates that the animal had a capacity for high-performance crushing of foods, suggesting feeding behaviors more similar to a giant panda than a modern-day kangaroo.

By combining mathematics with science, an interdisciplinary team found how changes in the shape of DNA structure affect the nuclei of nocturnal animals. Their findings could help explain how nocturnal animals, such as mice, see at night.

Researchers have shown that 10 different cancer drugs being given to about 1,000 human patients in clinical trials kill cancer in entirely different ways than previously thought.

Researchers have used tools developed to explore 3D movements and mechanics of modern-day fish jaws to analyze a fossil fish for the first time.

Scientists successfully conducted a first-in-human, FDA-approved Phase 1 clinical trial of an injectable hydrogel that aims to repair damage and restore cardiac function in heart failure patients who previously suffered a heart attack. The trial is the first to test a hydrogel designed to repair cardiac tissue. It is also the first to test a hydrogel made from the natural scaffolding of cardiac...

In the face of obesity, the sex hormone progesterone that helps females get and stay pregnant appears to also put them at increased, early risk for cardiovascular disease, investigators report.

Astronomers have discovered one of the largest features ever observed in the center of the Milky Way: a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy.

Using computational tools to investigate gene transcription networks in large collections of brain tissues, a scientific team has identified a gene that acts as a master regulator of schizophrenia during early human brain development. The findings may lay the groundwork for future treatments for the highly complex neuropsychiatric disorder.

Electrochemical reactions drive shape change in new nanoarchitected metamaterial.
