How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It's a deceptively complicated question, so a Rutgers-led group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.
Scientists at Oak Ridge National Laboratory used new techniques to create a composite that increases the electrical current capacity of copper wires, providing a new material that can be scaled for use in ultra-efficient, power-dense electric vehicle traction motors.
Federal funding of new technology is crucial for astronomy, according to results of a study released Sept. 21 in the Journal of Astronomical Telescopes, Instruments and Systems.
Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Hurricane Teddy's rainfall rates as it approaches Bermuda on Sept. 21. Teddy is a large hurricane and growing. It is also churning up seas all the way to the U.S. and Canadian coastlines.
In lab studies of wildfire, nitrous acid seems like a minor actor, often underrepresented in atmospheric models. But in the real-world atmosphere, during wildfires, the chemical plays a leading role—spiking to levels significantly higher than scientists expected, driving increased ozone pollution and harming air quality, according to a new study led by the University of Colorado Boulder and the...
While the power conversion efficiency of perovskite solar cells (PVSCs)—a future of solar cells—has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the...
Late blight is the most important pathogen in potato and causes devastation worldwide. The disease, caused by the oomycete Phytophthora infestans, was the trigger of the Irish Famine and still one of the most serious threats to potato production that causes significant economic losses.
New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19. In particular, a vaccine capable of eliciting a strong immune response could substantially reduce the future burden of infection, according to a new study.
Only in 2012 have satellites seen the summer floes in the polar north more withdrawn than in...
Artificial intelligence can speed the development of 3D-printed bioscaffolds that help injuries heal, according to researchers.

A new study indicates a well-known biomarker that serves as a marker for earlier diagnosis of neurodegenerative diseases is now detectable in the eye. Neurofilament light chain, a protein previously detected in cerebrospinal fluid and blood that is being explored as a biomarker to detect neurodegeneration, has now been identified in the vitreous humor, or fluid within the eye.
COVID-19 is a reminder that "we are all in it together" and the world needs a global response to the climate change crisis, David Attenborough said, as he launched a film about lessons learned during his seven decades as a television naturalist. The film "David Attenborough: A Life On Our Planet" sets out his "witness statement" on the destruction of the environment and ideas on how humans can...
Continued doubling of infection rate feared by top advisers is unlikely to happen, say some expertsCoronavirus – latest updatesSee all our coronavirus coverageOn one thing, everyone agrees: the UK is at a turning point.After a summer of crowded beaches and pubs reopening, followed by children returning to school and employees going back to the workplace, new cases of Covid-19 are definitely on...
A shark's skin is made up of thousands of armor-like scales, known as denticles. Now, humans are copying that pattern to fight the spread of...
Warming in the Arctic shrank the ice covering the polar ocean this year to its second-lowest extent in four decades, scientists announced Monday, yet another sign of how climate change is rapidly transforming the region. Satellites recorded this year's sea ice minimum at 3.74 million square kilometers on Sept. 15, only the second time the ice has been measured below 4 million square kilometers in...
During wildfires, nitrous acid plays a leading role -- spiking to levels significantly higher than scientists expected, driving increased ozone pollution and harming air quality, according to a new study.
When the COVID-19 pandemic first began, many non-urgent surgeries were delayed. Now, a new paper explains how to address the backlog of surgeries, without compromising patient outcomes.
A study of search and rescue dogs showed little difference in longevity or cause of death between dogs at the disaster site and dogs in a control group.
Scientists have used new techniques to create a composite that increases the electrical current capacity of copper wires, providing a new material that can be scaled for use in ultra-efficient, power-dense electric vehicle traction motors.
Fear and anxiety reflect overlapping brain circuits, according to research recently published in JNeurosci. The findings highlight a need to reevaluate the existing models guiding anxiety research.
Only in 2012 have satellites seen the summer floes in the polar north more withdrawn than in 2020.
