Each year, researchers from around the world visit the Department of Energy's SLAC National Accelerator Laboratory to conduct hundreds of experiments in chemistry, materials science, biology and energy research at the Linac Coherent Light Source (LCLS) X-ray laser. LCLS creates ultrabright X-rays from high-energy beams of electrons produced in a giant linear particle accelerator.
A new study warns mobile phones could be acting as 'Trojan horses' for coronavirus and urges billions of users worldwide to decontaminate their devices daily.
The research, led by Associate Professor Lotti Tajouri of Bond University, reviewed 56 studies from 24 countries and found phones host a staggering cocktail of live germs.
While all the studies predate the current pandemic, the authors say the virus responsible for COVID-19 -- SARS-CoV-2 -- is probably present on mobile phones and other touch-screen devices of coronavirus sufferers.
The COVID-19 pandemic has exploded across the globe, leaving healthcare staff, policy makers and ordinary people struggling. We still don't completely understand why some people are more severely affected by the virus than others.
With the coronavirus pandemic temporarily shuttering hair salons, many clients are appreciating, and missing, the ability of hair dye to cover up grays or touch up roots. However, frequent coloring, whether done at a salon or at home, can damage hair and might pose health risks from potentially cancer-causing dye components. Now, researchers reporting in ACS Central Science have developed a process to dye hair with synthetic melanin under milder conditions than traditional hair dyes.
DALLAS, April 29, 2020 -- Using e-cigarettes damages the arteries and blood vessel function much like smoking traditional cigarettes, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association, and funded through the Tobacco Center of Regulatory Science of the American Heart Association, the leading voluntary health organization devoted to a world of longer, healthier lives.
A new article published in Nature Communications applies stable isotope analysis to a collection of fossil human teeth from the islands of Timor and Alor in Wallacea to study the ecological adaptations of the earliest members of our species to reach this isolated part of the world. Because the Wallacean islands are considered extreme, resource poor settings, archaeologists believed that early seafaring populations would have moved rapidly through this region without establishing permanent communities. Nevertheless, this has so far been difficult to test.
Developers may struggle to find enough land to offset the biodiversity impacts of future development, according to a University of Queensland study.
UQ's Dr Laura Sonter said the challenges were evident worldwide and could significantly limit the ability to achieve global conservation goals.
"Most countries now have offsetting policies requiring developers to revegetate or protect areas of habitat and ecosystems, to compensate for biodiversity losses caused by their projects," Dr Sonter said.
An international study led by Melbourne researchers has discovered nine new genes linked to the most severe type of childhood speech disorder, apraxia.
The research analysed the genetic make-up of 34 affected children and young people, and showed that variations in nine genes likely explained apraxia in 11 of them. The genetic variations were caused spontaneously and not inherited from their parents.
Men with a history of obesity in their late teens are, in adult life, more at risk of a blood clot (thrombus) in a leg or lung, according to a study from the University of Gothenburg study shows. The risk rises successively and is highest in those who were severely obese in adolescence.
A research team including research scientist Atsuko Kobayashi from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, Japan and research scientist Mizuho Koike from the Institute of Space and Astronautical Science at Japan Aerospace Exploration Agency, have found nitrogen-bearing organic material in carbonate minerals in a Martian meteorite. This organic material has most likely been preserved for 4 billion years since Mars' Noachian age.
Last year, the 18th International Congress of Myriapodology brought together 92 of the world's top experts on the curious, yet still largely unknown multi-legged centipedes, millipedes, pauropods, symphylans (collectively referred to as myriapods) and velvet worms (onychophorans).
Results from a first-of-its-kind study of a multicancer blood test in more than 9,900 women with no evidence or history of cancer showed the liquid biopsy test safely detected 26 undiagnosed cancers, enabling potentially curative treatment.
A protein known to expand blood vessels -- key to controlling conditions like high blood pressure -- actually has different functions in males and females, new UC Davis Health research shows.
Conducted using arterial cells from mice, the study is the first to identify sex-based distinctions in how the protein --Kv2.1 -- works.
Kv2.1 is generally known to form calcium channels that dilate blood vessels. In arterial cells from female mice, however, it contracted blood vessels.
When people behave selfishly, they have a reliable ally to keep their self-image well-polished -- their own memory.
When asked to recall how generous they were in the past, selfish people tend to remember being more benevolent than they actually were, according to a series of experiments by Yale psychologists and economists at University of Zurich published April 29 in the journal Nature Communications.
Researchers in South Korea have developed ultra-fast transmitting/receiving optical engine that can provide stable and improved data transfer speed for data centers.
