Injections of a natural 'energy' molecule prompted regrowth of almost half of the cartilage lost with aging in knees, a new study in rodents shows.

The world's 'best of the last' tropical forests are at significant risk of being lost, according to a paper released today in Nature Ecology and Evolution. Of these pristine forests that provide key services--including carbon storage, prevention of disease transmission and water provision--only a mere 6.5 percent are formally protected.

Researchers from Columbia Engineering and the University of Pittsburgh have developed a sensitive and specific early warning system for predicting necrotizing enterocolitis (NEC) in premature infants before the life-threatening intestinal disease occurs. The prototype predicts NEC accurately and early, using stool microbiome features combined with clinical and demographic information. 'The lessons...

If voters gravitate toward the center of the political spectrum, why are the parties drifting farther apart? A new model reveals a mechanism for increased polarization in US politics, guided by the idea of 'satisficing'-- that people will settle for a candidate who is 'good enough.'

Characterizing traits of online activity may help to rescue victims of sex trafficking. While scientists have tried to help pinpoint outfits participating in trafficking, few scientific studies have looked of how the digital infrastructure behind the online sex market operates. A paper from Mayank Kejriwal, a research assistant professor at the USC Information Sciences Institute and Yao Gu...

A new study, revisiting fossil specimens from the enormous crocodylian, Deinosuchus, has confirmed that the beast had teeth "the size of bananas", capable to take down even the very largest of dinosaurs.

The rise in firearm violence has coincided with an increase in the severity of injuries firearms inflict as well as the cost of operations.

Scientists are closer to gaining the upper hand on Huanglongbing, a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable.

When the eye isn't getting enough oxygen in the face of common conditions like premature birth or diabetes, it sets in motion a state of frenzied energy production that can ultimately result in blindness, and now scientists have identified new points where they may be able to calm the frenzy and instead enable recovery.

An international team led by the Plant Phenotyping and Imaging Research Centre (P2IRC) at the University of Saskatchewan (USask) and researchers at Agriculture and Agri-Food Canada (AAFC) has decoded the full genome for the black mustard plant--research that will advance breeding of oilseed mustard crops and provides a foundation for improved breeding of wheat, canola and lentils.

Engineers at the National Institute of Standards and Technology (NIST) have developed a flexible, portable measurement system to support design and repeatable laboratory testing of fifth-generation (5G) wireless communications devices with unprecedented accuracy across a wide range of signal frequencies and scenarios.

A simple blood test that does not require overnight fasting has been found to be an accurate screening tool for identifying youth at risk for type 2 diabetes and heart disease risk later in life.

In a laboratory experiment with rats, Brazilian researchers succeeded in reversing natural processes associated with aging that lead to loss of bone density and strength.

A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.

A new study has confirmed what researchers already suspected to be the case: heat inactivates SARS-CoV-2 in human milk.

I went into the MRI bracing for the wave of panic I knew would come as soon as I was strapped down and inside the machine." In "A Tale of Two MRIs" by patient Lelainia Lloyd, her experiences--good and bad--are shared as part of an upcoming special issue of the Journal of Medical Imaging and Radiation Sciences, published by Elsevier.

Connections with friends and family are key to helping communities adapt to the devastating impact of climate change on their homes and livelihoods. The research found people are more empowered to deal with the impact of encroaching sea-levels and dwindling fish stocks when they see others doing the same.

Social protection programs can facilitate progress towards the Sustainable Development Goals (SDGs) but can also create trade-offs across divergent social and environmental goals that can undermine their effectiveness, say the authors of new research published in the journal PNAS. This is one of the largest studies on the sustainability implications of social protection, funded by the Grantham...

Altered brain connectivity may be one way prenatal depression influences child behavior, according to new research in JNeurosci.

In a publication in Nature Communications last Friday, NIOZ scientists Nina Dombrowski and Anja Spang and their collaboration partners describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation.

A Brown University School of Public Health research team found that differences in diagnosis coding practices has resulted in artificially inflated mortality rate comparisons to other hospitals.

Scientists have tracked a 'boomerang' earthquake in the ocean for the first time, providing clues about how they could cause devastation on land.

New findings show that reducing the amount of protein in the urine of patients with focal segmental glomerulosclerosis can significantly slow declines in kidney function and extend time before patients' kidneys fail.

Although macrophages (cells involved in the detection and destruction of bacteria and other harmful organisms as well as dead cells) are classified as immune cells functioning in the activation and resolution of tissue inflammation, it is now clear that they are critically involved in a variety of disease processes, such as chronic inflammatory diseases, tumor growth and metastasis and tissue...
