New Imaging Technique Shows How DNA Is Protected at Chromosomes' Ends

Feb. 11, 2016 — A new imaging technique has allowed researchers to see how DNA loops around a protein that aids in the formation of a special structure in telomeres. Telomeres are essentially caps on the ends of ... read more

Alternative Proteins Encoded by the Same Gene Have Widely Divergent Functions in Cells

Feb. 11, 2016 — In a first large-scale systematic study, researchers found that most sibling proteins -- known as 'protein isoform' encoded by the same gene -- often play radically different roles within ... read more

Remember Where You're Going? How Scent Helps

Feb. 10, 2016 — In bloodhounds and neutrophils, getting the scent is not enough. Dogs and immune cells have to remember the chemoattractant they are pursuing, even when it momentarily fades out or threatens to ... read more

Feb. 10, 2016 — DNA is unwound by a type of “pumpjack” mechanism, similar to the way one operates on an oil rig, a team of scientists suggests. This finding is based on new close-up images of the proteins that ... read more

Feb. 10, 2016 — Boxer Muhammad Ali famously declared his intent to 'float like a butterfly and sting like a bee,' but perhaps boxers should look to another type of insect for inspiration: the trap-jaw ant. ... read more

Feb. 10, 2016 — A 10-year collaborative project has discovered how the Atlantic molly is able to live in toxic hydrogen sulfide water. These fish live in caves and springs throughout Mexico and thrive in water so ... read more

Feb. 10, 2016 — A research project has tested the hypothesis that Asian common toad populations across Southeast Asia are genetically similar owing to their commensal nature and high dispersive ability. To the ... read more

Feb. 10, 2016 — The ocean's power to rein in carbon and protect the environment is vast but not well-understood. But now, an international team of scientists has begun to illuminate how the ocean plucks carbon ... read more

A New Method Furthers Understanding of Evolutionary Genetics

Feb. 10, 2016 — The ultimate goal of evolutionary biology is to understand how mutations in DNA shape the growth and behavior of all living things. Standard research tools facilitate genetic studies of closely ... read more

Feb. 10, 2016 — A scientific breakthrough gives researchers access to the blueprint of thousands of molecules of great relevance to medicine and biology. The novel technique, opens up an easy way to determine the ... read more

Feb. 10, 2016 — The whooping crane, with its snowy white plumage and trumpeting call, is one of the most beloved American birds, and one of the most endangered. As captive-raised cranes are re-introduced in ... read more

Feb. 10, 2016 — A bed of fossilized, methane dependent clams has for the first time been observed in the high Arctic. It tells the story of a thousand year long methane release ... read more

Chemical Cages: New Technique Advances Synthetic Biology

Feb. 10, 2016 — A clever means of localizing and confining enzymes and the substrate molecules they bind with has been presented by researchers, speeding up reactions essential for life ... read more

Starfish Reveal the Origins of Brain Messenger Molecules

Feb. 9, 2016 — Biologists have discovered the genes in starfish that encode neuropeptides -- a common type of chemical found in human brains. The revelation gives researchers new insights into how neural function ... read more

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. 9, 2016 — Swedish researchers have produced the world's first model car with a roof and battery made from wood-based carbon fiber -- a lightweight and renewable alternative to metals and other ... read more
