American hospitals are being targeted in a wave of ransomware attacks as covid-19 infections in the US break records and push the country’s health infrastructure to the brink. As reports emerge of attacks that interrupted healthcare in at least six US hospitals, experts and government officials say they expect the impact to worsen—and warn that the attacks could potentially threaten...

Space-based service will alert users to potential collisions between satellites and orbital junkThe Canadian company NorthStar Earth and Space has contracted Thales Alenia Space to build the first three satellites of its Skylark space traffic monitoring system, with LeoStella, a Seattle-based firm, overseeing the final assembly. This will make NorthStar the first commercial company to monitor...
A new study suggests myocarditis caused by COVID-19 may be a relatively rare occurrence.
Researchers have found that a more intensive, less frequent drug regimen with currently available therapeutics could cure the infection that causes Chagas disease.
An environmental health scientist has used an unprecedented objective approach to identify which molecular mechanisms in mammals are the most sensitive to chemical exposures.
Researchers expand their theory on converting graphene into 2D diamond, or diamane.
Our biological processes rely on a system of communications -- cellular signals -- that set off chain reactions in and between target cells to produce a response. The first step in these often complex communications is the moment a molecule binds to a receptor on or in a cell, prompting changes that can trigger further signals that propagate across systems. From food tasting and blood oxygenation...
Researchers have created a new model of how the coronavirus can spread through a community. The model factors in network exposure -- whom one interacts with -- and demographics to simulate at a more detailed level both where and how quickly the coronavirus could spread through Seattle and 18 other major cities.
An academic has helped draw up a landmark agreement amongst international experts, setting out the world's first standard guidance on how people with diabetes can use modern glucose monitoring devices to help them exercise safely. The guidance will be a crucial resource for healthcare professionals around the world, so they can help people with type 1 diabetes.
Pyrite, or fool's gold, is a common mineral that reacts quickly with oxygen when exposed to water or air, such as during mining operations, and can lead to acid mine drainage. Little is known, however, about the oxidation of pyrite in unmined rock deep underground.
The plant pathogenic nematode Heterodera schachtii infects more than 200 different plants, including sugar beets, and causes significant economic losses. Over the past 50 years, the primary management tool in California has been crop rotation. When the number of H. schachtii in a soil exceeds a threshold, growers are contractually required by the local sugar factory to plant crops that do not...
Marrying two layers of graphene is an easy route to the blissful formation of nanoscale diamond, but sometimes thicker is better.
Many patients with pancreatic cancer have only about a 10% chance of survival within five years of their diagnosis because they tend to become resistant to chemotherapy, past studies have indicated.
As the country enters the final days of a marathon and polarizing election season, politicians' faces are everywhere. And that trend is not likely going anywhere, especially in the realm of social media.

Between 1992 and 2015, the world's most biologically diverse places lost an area more than three times the size of Sweden when the land was converted to other uses, mainly agriculture, or gobbled up by urban sprawl.
We know how search engines can favor certain results and how social media might push us into bubbles, but it's still easy to view the internet as a place where we're in control.
One year ago, a report from the Johns Hopkins Center for Health Security assessed the readiness of 195 countries around the world to confront a deadly disease outbreak. Topping the list of most-prepared nations was the United States of America.
Heralded as one of the greatest success stories of the Endangered Species Act, the gray wolf will lose federal protections under a Trump administration decision announced Thursday.
One of the wild horses that roam the Outer Banks was found dead on a beach at Cape Lookout National Seashore, and the cause remains a mystery, the National Park Service said Wednesday.
Science's steady march to find a vaccine capable of ending the coronavirus pandemic may come at the expense of another species: sharks.
A study of dog DNA patterns shows that our "best friend" among animals is also our oldest one.

Scientists have used data from NASA's Cassini mission to delve into the impact craters on the surface of Titan, revealing more detail than ever before about how the craters evolve and how weather drives changes on the surface of Saturn's mammoth moon.
When satellites take pictures of Earth at night, how much of the light that they see comes from streetlights? A team of scientists from Germany, the U.S., and Ireland have answered this question for the first time, thanks to "smart city" lighting technology that allows cities to dim their lights. The results were published today in the journal Lighting Research & Technology.
Thanks to new research using data from the Kepler space telescope, it's estimated that there could be as many as 300 million potentially habitable planets in our galaxy. Some could even be pretty close, with several likely within 30 light-years of our Sun. The findings will be published in The Astronomical Journal, and research was a collaboration of scientists from NASA, the SETI Institute, and...
With days still to go before the US presidential election, early voting has already topped half of all votes cast in the 2016 election, and every indication is that the electorate is energized. It makes sense, then, that in this heavily contested, highly polarized political environment (in the midst of a raging pandemic, no less), disinformation…
A NASA spacecraft more than 200 million miles away has tucked asteroid samples into a capsule for return to Earth, after losing some of its precious loot, scientists said Thursday.
Many of the fundamental principles in biology and essentially all pathways regulating development were identified in so-called genetics screens. Originally pioneered in the fruit fly Drosophila and the nematode C. elegans, genetic screens involve inactivation of many genes one by one. By analyzing the consequences of gene loss, scientists can draw conclusions about its function. This way, for...
There are nearly one million catalogued asteroids, but we don't know much about many of them. Now Unistellar and its scientific partner, the SETI Institute, can count on a network of nearly 3,000 amateurs capable of observing thousands of asteroids and providing an estimate of their size and shape. With mobile stations located in Asia, North America and Europe, the Unistellar network, the largest...
Zooplankton can grow faster and produce more offspring when exposed to a substance that affects human happiness.
Professor Arakawa Masahiko (Graduate School of Science, Kobe University, Japan) and members of the Hayabusa2 mission discovered more than 200 boulders ranging from 30 cm to 6m in size, which either newly appeared or moved as a result of the artificial impact crater created by Japanese spacecraft Hayabusa2's Small Carry-on Impactor (SCI) on April 5th, 2019. Some boulders were disturbed even in...
Colors are often essential to convey scientific data, from weather maps to the surface of Mars. But did you ever consider that a combination of colors could be "unscientific?" Well, that's the case with color scales that use rainbow-like and red–green colors, because they effectively distort data. And if that was not bad enough, they are unreadable to those with any form of color blindness....
For the first time, a team at HZB has identified the atomic substructure of amorphous silicon with a resolution of 0.8 nanometres using X-ray and neutron scattering at BESSY II and BER II. Such a-Si:H thin films have been used for decades in solar cells, TFT displays, and detectors. The results show that three different phases form within the amorphous matrix, which dramatically influences the...
The phenomenon of molecular outflow was first discovered in the 1980's. Very high velocity motions were detected in the line wings of the carbon monoxide (CO) molecule, seen towards young forming stars. The high velocity motions obviously could not be gravitationally bound motions (such as infall or rotation) because of the required large gravitating masses. The first detections were in fact in...
