New family of atomic-thin electride materials discovered
An exploratory investigation into the behavior of materials with desirable electric properties has resulted in the discovery of a structural phase of two-dimensional (2D) materials. The new family of materials are electrides, wherein electrons occupy a space usually reserved for atoms or ions instead of orbiting the nucleus of an atom or ion. The stable, low-energy, tunable materials could have...
Ocean microplastics: First global view shows seasonal changes and sources
An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics—tiny flecks that can ride currents hundreds or thousands of miles from their point of entry.
'Disagreeable' married men who shirk domestic responsibilities earn more at work
Married men who don't help out around the house tend to bring home bigger paychecks than husbands who play a bigger role on the domestic chores front.
Butterflies and moths have difficulty adjusting to a rapidly changing climate
Climate change exerts great pressure for change on species and biodiversity. A recent study conducted by the University of Helsinki and the Finnish Environment Institute indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of...
How do plants balance microbial friends and foes?
Plants are constantly exposed to microbes: Pathogens that cause disease, commensals that cause no harm or benefit, and mutualists that promote plant growth or help fend off pathogens. For example, most land plants can form positive relationships with arbuscular mycorrhizal fungi to improve nutrient uptake. How plants fight off pathogens without also killing beneficial microbes or wasting energy on...

Climate change exerts great pressure for change on species and biodiversity. A recent study indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of Lepidoptera species have not been able to respond in either way, seeing their...
Study sheds light on treatment options for devastating childhood brain cancer
- ScienceDaily
- 21/6/10 22:24
Research suggests that children with average risk medulloblastoma can receive radiation to a smaller volume of the brain at the end of a six-week course of treatment and still maintain the same disease control as those receiving radiation to a larger area. But the dose of preventive radiation treatments given to the whole brain and spine over the six-week regimen cannot be reduced without reducing...
Study identifies how COVID-19 linked to Alzheimer's disease-like cognitive impairment
- ScienceDaily
- 21/6/10 22:24
A new study has identified mechanisms by which COVID-19 can lead to Alzheimer's disease-like dementia. The findings indicate an overlap between COVID-19 and brain changes common in Alzheimer's, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.
Common diabetes drug shows promise as treatment for COVID-19 lung inflammation
- ScienceDaily
- 21/6/10 22:24
Researchers identify the molecular mechanism for the anti-inflammatory activity of diabetes drug metformin and, in mouse studies, say it prevents lung inflammation in animals infected with SARS-CoV-2, the virus that causes COVID-19.

Researchers have created a first-of-its-kind metalens - a metamaterial lens - that can be focused using voltage instead of mechanically moving its components.
Forget me not: Novel target shows promise in treating Alzheimer's and related dementias
- ScienceDaily
- 21/6/10 22:23
Researchers have identified a previously unknown early driver of Alzheimer's disease (AD) and vascular dementia (VaD). They report high levels of cis P-tau, a pathogenic protein, in human AD and VaD brains as well as preclinical disease models. Treatment with an antibody to the toxic protein prevented disease progression and reversed disease symptoms and restored cognitive function in older mice.
Music listening near bedtime disruptive to sleep
- ScienceDaily
- 21/6/10 22:23
Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When a sleep researcher realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music -- and particularly stuck songs -- might affect sleep patterns.
Machine learning model doubles accuracy of global landslide 'nowcasts'
Every year, landslides—the movement of rock, soil, and debris down a slope—cause thousands of deaths, billions of dollars in damages, and disruptions to roads and power lines. Because terrain, characteristics of the rocks and soil, weather, and climate all contribute to landslide activity, accurately pinpointing areas most at risk of these hazards at any given time can be a challenge. Early...

Venus is hotter than ever, with a third new robotic explorer on the horizon.
Study shows how permafrost releases methane in the warming Arctic
Researchers from Skoltech have designed and conducted experiments measuring gas permeability under various conditions for ice-containing sediments mimicking permafrost. Their results can be useful both in modeling and testing techniques for gas production from Arctic reservoirs and in tracing methane emission in high latitudes. The paper was published in the journal Energy & Fuels.
Printing flexible wearable electronics for smart device applications
The demand for flexible wearable electronics has spiked with the dramatic growth of smart devices that can exchange data with other devices over the internet with embedded sensors, software, and other technologies. Researchers consequently have focused on exploring flexible energy storage devices, such as flexible supercapacitators (FSCs), that are lightweight and safe and easily integrate with...
How butterflies make transparent wings: Scientists see the invisible
Many animals have evolved camouflage tactics for self-defense, but some butterflies and moths have taken it even further: They've developed transparent wings, making them almost invisible to predators.
Study on plant roots challenges nature of ecological trade-offs
The specific traits of a plant's roots determine the climatic conditions under which a particular plant prevails. A new study led by the University of Wyoming sheds light on this relationship—and challenges the nature of ecological trade-offs.
Scientists uncover the mysteries of how viruses evolve
An international team of researchers have shed new light on the early stages of viral evolution.
Vanadium-dependent nitrogenase can bind two CO molecules simultaneously
Through the biological fixation of the element nitrogen by the enzyme nitrogenase, organisms gain access to molecular nitrogen (N2) in the Earth's atmosphere, which is essential for building cellular structures. In addition, a vanadium-dependent variant of nitrogenase can reduce the toxic gas carbon monoxide (CO) to hydrocarbons. These reductions of N2 and CO are among the most important processes...
Searching for heavy new particles with the ATLAS Experiment
Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments have measured its mass to be around 125 GeV—yet the Standard Model implies it has much larger mass and requires a very large correction to the mathematics in order to align...

The Uttarakhand region of India experienced a humanitarian tragedy on Feb. 7, 2021, when a wall of debris and water barreled down the Ronti Gad, Rishiganga and Dhauliganga river valleys. This debris flow destroyed two hydropower facilities and left more than 200 people dead or missing. A self-organized coalition of 53 scientists came together in the days following the disaster to investigate the...
