A stopgap measure to treat respiratory distress
A stopgap measure to treat respiratory distress
Repurposing a drug used for blood clots may help Covid-19 patients in danger of respiratory failure, researchers suggest. Researchers at MIT and the University of Colorado at Denver have proposed a stopgap measure that they believe could help Covid-19 patients who are in acute respiratory distress. By repurposing a drug that is now used to treat blood clots, they believe they could help people in cases where a ventilator is not helping, or if a ventilator is not available.

Ships' emissions create measurable regional change in clouds
Ships’ emissions create measurable regional change in clouds
A container ship leaves a trail of white clouds in its wake that can linger in the air for hours. This puffy line is not just exhaust from the engine, but a change in the clouds that's caused by small airborne particles of pollution. New research led by the University of Washington is the first to measure this phenomenon's effect over years and at a regional scale.

Brain or muscles, what do we lose first?
Brain or muscles, what do we lose first?
Researchers have shown that the decline in cognitive abilities after 50 years of age results in a decline in physical activity, and that - contrary to what has been suggested by the literature to date - the inverse relationship is much weaker. Someone dies somewhere in the world every 10 seconds owing to physical inactivity - 3.2 million people a year according to the World Health Organisation (WHO).

Electric cars better for climate in 95% of the world
Electric cars better for climate in 95% of the world
Fears that electric cars could actually increase carbon emissions are unfounded in almost all parts of the world, new research shows. Understanding the effect of low-carbon innovations on relevant sectors of the economy, such as heating and transport, is crucial for the development of effective policy Pablo Salas Reports have questioned whether electric cars really are 'greener' once emissions from production and generating their electricity are taken into account.

Uncertainty about facts can be reported without damaging public trust in news - study
A series of experiments - including one on the BBC News website -finds the use of numerical ranges in news reports helps us grasp the uncertainty of stats while maintaining trust in data and its sources.  Ultimately we'd like to see the cultivation of psychological comfort around the fact that knowledge and data always contain uncertainty Sander van der Linden The numbers that drive headlines - those on Covid-19 infections, for example - contain significant levels of uncertainty: assumptions, limitations, extrapolations, and so on.

Breast cancer screening costs high, benefits uncertain, for women in 40s
There are substantial costs associated with breast cancer screenings for U.S. women in their 40s, a new Yale-led study finds, and these costs vary widely by region. The study, conducted by researchers at Yale, University of Oslo, and New York University, found that over 40% of the eligible, privately insured women ages 40-49 received annual breast cancer screening in 2017 and estimated the national cost of those procedures to be $2.13 billion per year.

UChicago chemists race to decode RNA of new coronavirus
As scientists around the world race to decode the coronavirus that has caused more than 15,000 deaths in a matter of months, a group of University of Chicago chemists are focusing on understanding how the virus's RNA works-which could translate to a more effective vaccine. COVID-19, like many other viruses, is made solely out of RNA, the set of molecules that most of us remember learning in biology class as messengers that carry out instructions from DNA.

Automated speech recognition less accurate for blacks
The disparity likely occurs because such technologies are based on machine learning systems that rely heavily on databases of English as spoken by white Americans. The technology that powers the nation's leading automated speech recognition systems makes twice as many errors when interpreting words spoken by African Americans as when interpreting the same words spoken by whites, according to a new study by researchers at Stanford Engineering.

How social squid communicate in the dark
How social squid communicate in the dark
In the frigid waters 1,500 feet below the surface of the Pacific Ocean, hundreds of human-sized Humboldt squid feed on a patch of finger-length lantern fish. Zipping past each other, the predators move with exceptional precision, never colliding or competing for prey. How do they establish such order in the near-darkness of the ocean's twilight zone? The answer, according to researchers from Stanford University and the Monterey Bay Aquarium Research Institute (MBARI) may be visual communication.

"Thermometer" protein regulates blooming
As average temperatures rise every year, it is no longer rare to see plants flower as early as February. Behind this phenomenon is a complex of proteins whose activity is controlled by temperature changes, as has just been demonstrated by researchers from the Cell and Plant Physiology Laboratory (CNRS / CEA / INRAE / Université Grenoble Alpes) and their partners.

As climate change messes with temperature and precipitation, California newts suffer
California didn't get much of a break. Just three years after the 2011-2017 drought, one of the severest in recorded history for the state, the driest February in 150 years has spurred discussion of whether we're in another drought — or if the last one even ended. That's bad news for Los Angeles' only newt, California newt, Taricha torosa , and other newts in the Taricha genus, particularly in the southern half of the state south of Big Sur.

The growth of an organism rides on a pattern of waves
Study shows ripples across a newly fertilized egg are similar to other systems, from ocean and atmospheric circulations to quantum fluids. When an egg cell of almost any sexually reproducing species is fertilized, it sets off a series of waves that ripple across the egg's surface. These waves are produced by billions of activated proteins that surge through the egg's membrane like streams of tiny burrowing sentinels, signaling the egg to start dividing, folding, and dividing again, to form the first cellular seeds of an organism.
