Sat, 30 May 2020 17:26:12 EDT
For the first time in history, NASA astronauts have launched from American soil in a commercially built and operated American crew spacecraft on its way to the International Space Station.
New sunspots potentially herald increased solar activity
Sat, 30 May 2020 16:31:07 EDT
On May 29, 2020, a family of sunspots -- dark spots that freckle the face of the Sun, representing areas of complex magnetic fields -- sported the biggest solar flare since October 2017. Although the sunspots are not yet visible (they will soon rotate into view over the left limb of the Sun), NASA spacecraft spotted the flares high above them.
The fight goes on: Clinical trial shows promising new treatment for rare blood cancer
Sat, 30 May 2020 11:36:32 EDT
Although lymphoma is one of the most common types of blood cancer, it has a rare subtype for which no effective treatment regimens are known. For the first time, researchers have conducted clinical trials for a new treatment protocol and report it to be quite promising.
COVID-19 patients who undergo surgery are at increased risk of postoperative death
Fri, 29 May 2020 19:07:39 EDT
Patients undergoing surgery after contracting coronavirus are at greatly increased risk of postoperative death, a new global study reveals. Researchers found that amongst SARS-CoV-2 infected patients who underwent surgery, mortality rates approach those of the sickest patients admitted to intensive care after contracting the virus in the community.
How the coronavirus could be prevented from invading a host cell
Fri, 29 May 2020 19:07:37 EDT
How might the novel coronavirus be prevented from entering a host cell in an effort to thwart infection? A team of biomedical scientists has made a discovery that points to a solution. The scientists report that two proteases -- enzymes that break down proteins -- located on the surface of host cells and responsible for processing viral entry could be inhibited.
Scientists develop method to help epidemiologists map spread of COVID-19
Fri, 29 May 2020 19:07:34 EDT
Scientists have developed a method they believe will help epidemiologists more efficiently predict the spread of the COVID-19 pandemic. Their new study outlines a solution to the SIR epidemic model, which is commonly used to predict how many people are susceptible to, infected by, and recovered from viral epidemics.
Key player in hepatitis A virus infection
Fri, 29 May 2020 16:13:01 EDT
Researchers designed experiments using gene-editing tools to discover how molecules called gangliosides serve as de facto gatekeepers to allow the virus entry into liver cells and trigger disease.
Adolescent exposure to anesthetics may cause alcohol use disorder, new research shows
Fri, 29 May 2020 16:12:58 EDT
Early exposure to anesthetics may make adolescents more susceptible to developing alcohol use disorder (AUD), according to new research.
Evolution of pandemic coronavirus outlines path from animals to humans
Fri, 29 May 2020 16:12:21 EDT
A team of scientists studying the origin of SARS-CoV-2, the virus that has caused the COVID-19 pandemic, found that it was especially well-suited to jump from animals to humans by shapeshifting as it gained the ability to infect human cells.
A rising tide of marine disease? How parasites respond to a warming world
Fri, 29 May 2020 15:07:18 EDT
A recent study explores the ways parasitism will respond to climate change, providing researchers new insights into disease transmission.
Paper-thin gallium oxide transistor handles more than 8,000 volts
Fri, 29 May 2020 15:07:16 EDT
Electrical engineers created a gallium oxide-based transistor that can handle more than 8,000 volts. The transistor could lead to smaller and more efficient electronic systems that control and convert electric power -- a field of study known as power electronics -- in electric cars, locomotives and airplanes. In turn, this could help improve how far these vehicles can travel.
Paid sick leave mandates hold promise in containing COVID-19
Fri, 29 May 2020 15:07:14 EDT
Mandates like those found in the federal government's Families First Coronavirus Response Act may be helping to slow the pandemic.
Older men worry less than others about COVID-19
Fri, 29 May 2020 15:07:12 EDT
Older men may be at greater risk of contracting COVID-19 because they worry less about catching or dying from it, according to a new study.
Using brain imaging to demonstrate weaker neural suppression for those with autism
Fri, 29 May 2020 15:07:10 EDT
A new study shows the differences in visual motion perception in autism spectrum disorder are accompanied by weaker neural suppression in the visual cortex of the brain.
Integrating satellite and socioeconomic data to improve climate change policy
Fri, 29 May 2020 15:07:08 EDT
Bangladesh is on track to lose all of its forestland in the next 35-40 years, leading to a rise in CO2 emissions and subsequent climate change, researchers said. However, that is just one of the significant land-use changes that the country is experiencing. A new study uses satellite and census data to quantify and unravel how physical and economic factors drive land-use changes. Understanding this relationship can inform climate policy at the national scale in Bangladesh and beyond.
Yes, your dog wants to rescue you
Fri, 29 May 2020 15:07:06 EDT
Imagine you're a dog. Your owner is trapped in a box and is crying out for help. Are you aware of his despair? If so, can you set him free? And what's more, do you really want to? That's what researchers wanted to know when they gave dogs the chance to rescue their owners.
Smart windows that self-illuminate on rainy days
Fri, 29 May 2020 15:07:04 EDT
A research team develops self-powering, color-changing humidity sensors. Applicable to various fields including smart windows, health care and safety management.
New view on how tissues flow in the embryo
Fri, 29 May 2020 15:07:02 EDT
Watching and measuring what happens in tissues inside the human embryo is currently not possible, and it's difficult to do in mammalian models. Because humans and the fruit fly Drosophila share so many biological similarities, researchers tackled this problem by focusing on fruit flies. The team reports today that they can predict when the tissue will begin to rapidly flow just by looking at cell shapes in the tissue.
'Single pixel' vision in fish helps scientists understand how humans can spot tiny details
Fri, 29 May 2020 15:06:56 EDT
Recently discovered 'single-pixel vision' in fish could help researchers understand how humans are able to spot tiny details in their environment -- like stars in the sky.
Heightened interaction between neolithic migrants and hunter-gatherers in Western Europe
Fri, 29 May 2020 15:06:54 EDT
This study reports new genome-wide data for 101 prehistoric individuals from 12 archaeological sites in today's France and Germany, dating from 7000-3000 BCE, and documents levels of admixture between expanding early Neolithic farmers and local hunter-gatherers seen nowhere else in Europe.
