A study across New York City found that out-of-hospital sudden deaths follow the geographic distribution of SARS-CoV-2, suggesting an association between the two, investigators report.
A new archaeology for the Anthropocene era
Mon, 18 Jan 2021 11:31:32 EST
Scantily clad tomb raiders and cloistered scholars piecing together old pots -- these are the kinds of stereotypes of archaeology that dominate public perception. Yet archaeology in the new millennium is a world away from these images. In a major new report, researchers probe a thoroughly modern and scientific discipline to understand how it is helping to address the considerable challenges of the Anthropocene.
Climate change will alter the position of the Earth's tropical rain belt
Mon, 18 Jan 2021 11:31:29 EST
Researchers describe future changes to the tropical rain belt with expected climate change. The changes will cause droughts in large sections of the globe, threatening biodiversity and food security.
Inexpensive battery charges rapidly for electric vehicles, reduces range anxiety
Mon, 18 Jan 2021 11:31:26 EST
Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.
A 'super-puff' planet like no other
Mon, 18 Jan 2021 11:31:24 EST
Astronomers discover that the core mass of exoplanet WASP-107b is much lower than previously thought possible for a gas-giant planet.
Personalized brain stimulation alleviates severe depression symptoms
Mon, 18 Jan 2021 11:31:20 EST
Targeted neuromodulation tailored to individual patients' distinctive symptoms is an increasingly common way of correcting misfiring brain circuits in people with epilepsy or Parkinson's disease. Now, scientists have demonstrated a novel personalized neuromodulation approach that -- at least in one patient -- was able to provide relief from symptoms of severe treatment-resistant depression within minutes.
New management approach can help avoid species vulnerability or extinction
Mon, 18 Jan 2021 11:31:17 EST
Research focuses on transient nature of species' and ecosystem stability; illustrates how prepare for possible flips.
Low-carbon policies can be 'balanced' to benefit small firms and average households
Mon, 18 Jan 2021 11:31:12 EST
A review of ten types of policy used to reduce carbon suggests that some costs fall on those less able to bear them - but it also shows these policies can form the bedrock of a 'green recovery' if specifically designed and used in tandem.
Synthesis of potent antibiotic follows unusual chemical pathway
Mon, 18 Jan 2021 11:31:04 EST
Images of a protein involved in creating a potent antibiotic reveal the unusual first steps of the antibiotic's synthesis. The improved understanding of the chemistry behind this process could allow researchers to adapt this and similar compounds for use in human medicine.
New computational tool reliably differentiates between cancer and normal cells from single-cell RNA-sequencing data
Mon, 18 Jan 2021 11:30:40 EST
Researchers have developed a new computational tool to accurately differentiate between cancer cells and normal cells when analyzing large single-cell RNA-sequencing data.
Students returning home may have caused 9,400 secondary COVID-19 infections across UK
Mon, 18 Jan 2021 10:35:06 EST
A new statistical model suggests that an infected student returning home for Christmas would, on average, have infected just less than one other household member.
Many parents say teens with anxiety, depression may benefit from peer confidants at school
Mon, 18 Jan 2021 10:34:58 EST
Three-quarters of parents in a new national poll think peers better understand teen challenges, compared to teachers or counselors in the school.
Eliminating microplastics in wastewater directly at the source
Mon, 18 Jan 2021 10:34:56 EST
A research team has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source.
Scientists reveal mechanism that causes irritable bowel syndrome
Sun, 17 Jan 2021 13:22:38 EST
Researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel syndrome and other food intolerances. The study was carried out in mice and humans.
One small alcoholic drink a day is linked to an increased risk of atrial fibrillation
Sun, 17 Jan 2021 13:22:31 EST
A study of nearly 108,000 people has found that people who regularly drink a modest amount of alcohol are at increased risk of atrial fibrillation, a condition where the heart beats in an abnormal rhythm. The study found that, compared to drinking no alcohol at all, just one alcoholic drink a day was linked to a 16% increased risk of atrial fibrillation over an average follow-up time of nearly 14 years.
Rapid blood test identifies COVID-19 patients at high risk of severe disease
Sun, 17 Jan 2021 13:22:27 EST
Scientists have shown that a relatively simple and rapid blood test can predict which patients with COVID-19 are at highest risk of severe complications or death. The blood test measures levels of mitochondrial DNA, which normally resides inside the energy factories of cells. Mitochondrial DNA spilling out of cells and into the bloodstream is a sign that a particular type of violent cell death is taking place in the body.
COVID-19 pandemic in Brazil has overwhelmed its health systems, analysis shows
Sun, 17 Jan 2021 13:22:23 EST
An analysis of the first 250,000 patients admitted to hospital with coronavirus reveals a high mortality and inequities in the quality of healthcare across regions.
Scientists offer road map to improve environmental observations in the Indian Ocean
Fri, 15 Jan 2021 16:33:50 EST
A group of more than 60 scientists have provided recommendations to improve the Indian Ocean Observing System (IndOOS), a basin-wide monitoring system to better understand the impacts of human-caused climate change in a region that has been warming faster than any other ocean.
Glass frogs living near roaring waterfalls wave hello to attract mates
Fri, 15 Jan 2021 15:53:38 EST
A conservationist has discovered that the glass frog Sachatamia orejuela can be added to the list of species that make use of visual cues in response to their acoustic environments. This is the first time a member of the glass frog family (Centrolenidae) has been observed using visual communication in this manner.
Conductive nature in crystal structures revealed at magnification of 10 million times
