Indigenous subsistence of the Bears Ears region modified the landscape, leaving ecological legacies that persist today. A blend of Indigenous knowledge and western science can be used to build management plans for effective stewardship of the region's botanical and cultural resources.

Cultural diversity -- indicated by linguistic diversity -- and biodiversity are linked, and their connection may be another way to preserve both natural environments and Indigenous populations in Africa and perhaps worldwide, according to an international team of researchers.

Monoclonal antibodies, a COVIDa-19 treatment given early after coronavirus infection, cut the risk of hospitalization and death by 60% in those most likely to suffer complications of the disease, according to an analysis of UPMC patients who received the medication compared to similar patients who did not.

Early preterm births may be dramatically decreased with docosahexaenoic acid (DHA) supplements, with a dose of 1000 mg more effective for pregnant women with low DHA levels than the 200 mg found in some prenatal supplements.

Research team from Cincinnati Children's reports that excessive fat deposition in the liver due to obesity can alter the microenvironment of the liver in a way that attracts a highly specific population of immune T cells to the liver. These cells help trigger NAFLD.

Konstantinos Giapis delves into the science of the iconic accident for a PBS special.

So far, only a handful of siRNA, or other RNA interference-based therapeutics that can shut down harmful genes to keep viruses from spreading have been approved. Chemical engineering researchers in the Cockrell School of Engineering have created several nanoparticles to help solve the problem of getting the siRNA into the body and guiding it to the target.

New research from the University of Notre Dame helps to close the gap between what is and isn't known about food recalls.

It is a photoreceptor of cyanobacteria which protects them from excessive exposure to light. The design and production of a mutant variant of OCP and exploitation of state-of-the-art spectroscopic approaches made it possible to describe a photochemcial reaction that is new for carotenoids. These results will open up prospects for the development of new light-controlled systems and biomaterials.

A team of scientists from The Wistar Institute in Philadelphia and the Peter MacCallum Cancer Center in Melbourne, Australia, discovered a new checkpoint mechanism that fine-tunes gene transcription.

An international study has found that four out of five women in prison in Scotland have a history of head injury, mostly sustained through domestic violence. Published recently in The Lancet, researchers, including SFU psychology graduate student Hira Aslam, say the study has important implications for the female prison population more broadly and could help to inform mental health and criminal justice policy development.

Microdiamonds with nitrogen vacancy centers are increasingly used as biological tracers thanks to the optical fluorescence of NV centers. But the NV centers also can be spin-polarized by low-power lasers, and the polarized centers then polarize nearby carbon-13 atoms occurring naturally in the diamonds. These hyperpolarized C-13 atoms can be detected by NMR imaging. UC Berkeley chemists now demonstrate dual-mode imaging with NV-center diamonds, potentially allowing high-quality imaging 10 times deeper than with optics alone.

A new technology developed by UZH researchers enables the body to produce therapeutic agents on demand at the exact location where they are needed. The innovation could reduce the side effects of cancer therapy and may hold the solution to better delivery of Covid-related therapies directly to the lungs.

Scientists have detected new early-warning signals indicating that the central-western part of the Greenland Ice Sheet may undergo a critical transition relatively soon. Because of rising temperatures, a new study by researchers from Germany and Norway shows, the destabilization of the ice sheet has begun and the process of melting may escalate already at limited warming levels. A tipping of the ice sheet would substantially increase long-term global sea level rise.

Following the progression of breast cancer in an animal model revealed a path that transforms a slow-growing cancer type known as estrogen receptor (ER)+/HER2+ into a fast-growing ER-/HER2+ type that aggressively spreads or metastasizes to other organs.

Intact rainforests across tropical Africa continued to remove carbon from the atmosphere before and during the 2015-2016 El Niño, despite the extreme heat and drought. Theyl removed 1.1 billion tonnes of carbon dioxide per year from the atmosphere during the El Niño monitoring period. This rate is equivalent to three times the carbon dioxide emissions of the UK in 2019. Scientists were surprised by this discovery.

There are roughly 50 billion individual birds in the world, a new big data study by UNSW Sydney suggests - about six birds for every human on the planet.

A new open-access research collection published in Ecosphere reveals unexpected lessons drawn from decades of rich data from the Long Term Ecological Research (LTER) Network.

Researchers at Washington University School of Medicine in St. Louis have found that although the vast majority of people with alcohol use disorder see their doctors regularly for a range of issues, fewer than one in 10 ever get treatment to help curb their drinking.

Amid the rising toll of opioid overdoses and deaths in the U.S., several states are considering laws enabling civil commitment for involuntary treatment of patients with substance use disorders (SUDs). Most addiction medicine physicians support civil commitment for SUD treatment - but others strongly oppose this approach, reports a survey study in Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine (ASAM).
