Where COVID-19 hit hardest, sudden deaths outside the hospital increased, study finds

Monday January 18th, 2021 04:31:34 PM
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

Monday January 18th, 2021 04:31:32 PM
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

Monday January 18th, 2021 04:31:29 PM
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

Monday January 18th, 2021 04:31:26 PM
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

Monday January 18th, 2021 04:31:24 PM
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

Monday January 18th, 2021 04:31:20 PM
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

Monday January 18th, 2021 04:31:17 PM
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

Monday January 18th, 2021 04:31:12 PM
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

Monday January 18th, 2021 04:31:04 PM
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

Monday January 18th, 2021 04:30:40 PM
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

Monday January 18th, 2021 03:35:06 PM
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

Monday January 18th, 2021 03:34:58 PM
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

Monday January 18th, 2021 03:34:56 PM
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

Sunday January 17th, 2021 06:22:38 PM
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

Sunday January 17th, 2021 06:22:31 PM
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

Sunday January 17th, 2021 06:22:27 PM
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

Sunday January 17th, 2021 06:22:23 PM
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

Friday January 15th, 2021 09:33:50 PM
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

Friday January 15th, 2021 08:53:38 PM
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

Friday January 15th, 2021 08:53:23 PM
In groundbreaking materials research, a team has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows -- transparency and conductivity.
