Common Gene Variant Influences Food Choices ... for Better or Worse

Feb. 9, 2016 — Scientists have recently discovered that for girls who are carriers of a particular gene variant (DRD4 VNTR with 7 repeats), the crucial element that influences a child's fat intake is not the ... read more

Feb. 8, 2016 — New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists ... read more

Feb. 8, 2016 — Gene expression in a fruit fly embryo can be accurately and predictably tuned, new research shows. This study has important implications in cellular and developmental biology, with potential ... read more

Expression of a 'Ouija Board' Protein That Can Summon 'Monster' Genes

Feb. 8, 2016 — Biologists have studied Drosophila melanogaster flies to discover a new protein dubbed “Ouija Board,” which plays an important role in the biosynthesis of the steroid hormones necessary for ... read more

Feb. 5, 2016 — Sorry, Explorers Club, but woolly mammoth is no longer on the menu. Neither is the giant ground ... read more

Feb. 5, 2016 — First-ever interlaboratory study of four versions of a therapeutic protein drug -- all manufactured from living cells -- reports that an established analytical tool akin to magnetic resonance imaging ... read more

Feb. 5, 2016 — Cells reach a state called senescence when they stop dividing in response to DNA damage. This change can matter greatly to health, but scientists do not yet have a clear picture of how this change ... read more

Feb. 5, 2016 — The ability to see the direction in which something is moving is vital for survival. Only in this way is it possible to avoid predators, capture prey or, as humans in a modern world, cross a road ... read more

Feb. 5, 2016 — Cells are not uniform spheres; they generally come in a variety of disparate shapes. In the broadest sense, this variation in shapes is known as cell polarity, and it is an essential property for a ... read more

Feb. 5, 2016 — IBS researchers create multiplex Digenome-seq to find errors in CRISPR-Cas9 ... read more

Feb. 4, 2016 — Using a special profiling technique, researchers have determined the mechanism of action of a potent antibiotic, known as tropodithietic acid, leading them to uncover its hidden ability as a ... read more

Feb. 4, 2016 — Researchers have discovered a molecular regulator that allows salmonella bacteria to switch from actively causing disease to lurking in a chronic but asymptomatic state called a ... read more

Feb. 4, 2016 — Scientists have for the first time reengineered a building block of a geometric nanocompartment that occurs naturally in bacteria to give it a new ... read more

Feb. 4, 2016 — New research identifies two new enzymes in bacteria that help fight off infection at a later stage, after an invading virus has already begun to replicate. The enzymes are part of the CRISPR-Cas ... read more

Feb. 4, 2016 — Scientists have made an exciting discovery that could provide a new way to prevent bacterial infections in both humans and plants without triggering multi-drug resistance in ... read more

Hair Thinning by Stem Cell Loss

Feb. 4, 2016 — Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their ... read more

Leading Bugs to the Death Chamber: A Kinder Face of Cholesterol

Feb. 4, 2016 — Cells of our immune system kill pathogens by enclosing them in a compartment called the phagosome. The pathogen-containing phagosome is physically transported to execution chambers (lysosomes) by ... read more

Feb. 4, 2016 — DNA evidence lifted from the ancient bones and teeth of people who lived in Europe from the Late Pleistocene to the early Holocene -- spanning almost 30,000 years of European prehistory -- has ... read more

Feb. 4, 2016 — Each year, as bears prepare to hibernate, they gorge themselves on food to pack on fat. And yet, despite the rapid weight gain, the animals somehow avoid the health consequences so often associated ... read more

Feb. 4, 2016 — On Nov. 11, 1954, Syuiti Mori turned out the lights on a small group of fruit flies. More than 60 years later, the descendants of those flies have adapted to life without light. These flies -- a ... read more
