Feb. 12, 2016 — A research wildlife biologists have created a series of motion-sensitive camera traps to monitor golden eagle migration and distribution in southwest ... read more

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

Feb. 11, 2016 — Scientists have modified a plant gene that normally fights bacterial infection to confer resistance to a virus. The method is the first time a plant's innate defense system has been altered to ... read more

Breaking Cell Barriers With Retractable Protein Nanoneedles

Feb. 11, 2016 — Researchers have adapted a retractable protein polymer -- found naturally in certain bacteria -- to mechanically rupture cell membranes, which could lead to new drug delivery methods and other ... read more

New Target Found in Search for New, More Effective Herbicide

Feb. 11, 2016 — A new target in plants for the development of new herbicides for use by farmers and gardeners has been identified by researchers studying an enzyme in plants called DNA gyrase. In plants, DNA gyrase ... 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

Social Animals Seek out the Company of Others Because Their Brains Are Wired to Find It Rewarding

Feb. 11, 2016 — Social animals are strongly motivated to seek out the company of others, especially after periods of isolation, because their brains are wired to find it rewarding. A study now reveals a neural ... read more

Feb. 11, 2016 — When ground-nesting wasps leave their nests each day, they turn back toward home before flying along a series of ever-increasing arcs. While the insects gain height and distance, their attention ... read more

Feb. 11, 2016 — Almost all of our genes may be influenced by the food we eat, suggests new research. The study, carried out in yeast -- which can be used to model some of the body's fundamental processes -- ... read more

Feb. 11, 2016 — Researchers have discovered how cells in the human body build their own ‘railway networks’, throwing light on how diseases such as bowel cancer work. The microtubule tracks are vital for ... read more

Feb. 11, 2016 — A new study shows that a relatively high intake of dietary cholesterol, or eating one egg every day, are not associated with an elevated risk of incident coronary heart disease. Furthermore, no ... 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 — The human fingertip is a finely tuned sensory machine, and even slight touches convey a great deal of information about our physical environment. It turns out, some fish use their pectoral fins in ... 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
