But melanin can also block the ultraviolet radiation (UVB) that triggers vitamin D production in the skin. This is an advantage in the tropics, where UVB radiation is barely filtered by the atmosphere above.Anil AnanthaswamyNew scientist

gym n./tan v./a stack of ( )/A tanning bed or sunbed is a device emitting ultraviolet radiation (n.) (typically 95% UVA and 5% UVB, +/-3%) used to produce a cosmetic tan. There are a few units called high pressure beds that generate primarily UVA with some UVB but these are ...
that's big and strong enough to head straight into the sun goes out with a serious bang. After accelerating to more than 370 miles per second, the comet is flattened by the sun's atmosphere, generating a fantastic explosion thatthrows out cosmic tidal waves of ultraviolet radiation and x-...
Circulating endocannabinoids are increased in patients with cirrhosis (Fernandez-Rodriguez et al, 2004); chronic hepatitis C infection (Patsenker et al, 2015); exposure to solar ultraviolet radiation (Felton et al, 2017); congestive heart failure (Weis et al, 2010b); and atherosclerosis (Maeda ...
Interstellar space is the area between the stars, but it is far from empty. It contains vast quantities of neutrinos, charged particles, atoms, molecules, dark matter and photons ranging from the highest-energy radiation to the sluggish light of the cosmic microwave background (CMB) albeit rathe...
Tardigrades can also weather many noxious chemicals, boiling alcohol, the low pressure of a vacuum, and can survive six times the pressure of the deepest part of the oceans. Add to that the fact that these creatures can take ultraviolet radiation and survive the vacuum of space and you've ...
This shallow water could haveprotected the microbes and any other life from the sun's normally lethal ultravioletradiation. Metalsin the rocks would have made sure that the water wasn't too acidic. Over timeother organisms could have colonized the area after the first microbes had madeconditions...
“We were all surprised to find water so high in the atmosphere,” said Shane W. Stone, a doctoral student in planetary science at the University of Arizona’s Lunar and Planetary Laboratory in Tucson. “The measurements we used could have only come from MAVEN as it soars through th...
