Using overpasses as shelter from tornado?
2hMeteorologists and emergency workers continue to contest the popular thinking that waiting out a tornado under an overpass is safe.

Effect of small polyanions on retroviruses
6hA retrovirus is a virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing that cell's genome. Once inside the host cell's cytoplasm, the virus uses its reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro. The host cell then treats the viral DNA as part of its genome, transcribing and translating th

Astronomers once wondered if there were other planets in the heavens, and we certainly know the answer to that one: a resounding yes. With the help of instruments like the dearly departed Kepler Space Telescope, we've discovered thousands of exoplanets , but most of those are within a few thousand light-years of Earth. A new discovery courtesy of NASA's Chandra X-ray Observatory could point the w

6hCell [New Results]
DNA, the hereditary material, interacts with proteins in the nuclei of cells to form a tightly packed complex with proteins, which is referred to as "chromatin." The molecular architecture of the chromatin regulates access to genes, and therefore determines which genes can be activated in different cell types. Various chemical modifications of proteins called histones—which play a decisive role in

Why some of Darwin's finch nestlings have yellow beaks
6hCarotenoids are the underlying pigment for much of the enormous variety of color found across birds and form the basis for the colors red, yellow and orange. In a study published in Current Biology, researchers from Uppsala University and Princeton University have uncovered the genetic basis for the yellow beak of some Darwin's finch nestlings.
CRISPR-based approach reveals Achilles' heels of a common herpesvirus
6hMany people—around half of the adult population—are infected with a type of herpesvirus called human cytomegalovirus, or HCMV. Though mostly asymptomatic, the virus can be dangerous for immunocompromised people and unborn babies. Because HCMV is so widespread, the chance of a baby becoming infected in utero is around one in 200, and that infection can lead to problems with the baby's brain, lungs
