Using, Sharing, New Technologies Is Key for Conservation

Oct. 5, 2015 — Scientists estimate that we are losing species at 1,000 times the natural background rate. New technologies are improving conservation efforts by making it easier, faster, and cheaper to monitor ... read more

New Metabolomic Platform Reveals Fundamental Flaw in Common Lab Technology

Oct. 5, 2015 — A technology used in thousands of laboratories, called gas chromatography mass spectrometry, fundamentally alters the samples it analyzes, new research ... read more

Oct. 2, 2015 — Scientists have compared the diets of two caterpillar species, expecting the one that exclusively consumed plants containing toxic chemicals would more easily incorporate toxins into its body than ... read more

Pathogen-Carrying Neotropical Ticks Ride Migratory Birds Into US

Oct. 2, 2015 — Tick species not normally present in the United States are arriving here on migratory birds. Some of these ticks carry disease-causing Ricksettia species, and some of those species are exotic to the ... read more

Oct. 2, 2015 — As the largest animals to have ever lived on Earth, blue whales maintain their enormous body size through efficient foraging strategies that optimize the energy they gain from the krill they eat, ... read more

Oct. 2, 2015 — Scientists have gained new insight into the formation of the spindle, which is the molecular machine that divides up genetic material prior to cell division. Their work focuses on the motor protein, ... read more

Researchers Design 'Biological Flashlight' Using Light-Producing Ability of Shrimp

Oct. 2, 2015 — Researchers describe the design and engineering of the new bioluminescent imaging tool called the “LumiFluor” in a new report. Using the natural light-producing ability of deep-sea shrimp, the ... read more

Oct. 2, 2015 — Researchers recently described three new species of Acanthiophilus, a genus of fruit flies that infest plants of the tribe Cardueae (thistles) within the family Asteraceae. Members of this genus live ... read more

Oct. 2, 2015 — A novel micro-technology, which captures the electrical power generated by the photosynthesis and respiration of blue-green algae, has been created by ... read more

Studying Cardiac Arrhythmias in Nematodes

Oct. 2, 2015 — A simple model using the nematode Caenorhabditis elegans has been developed that can be used to test substances for treating genetically-mediated cardiac arrhythmias. They used the nematode feeding ... read more

Oct. 1, 2015 — A new study has identified a number of genes that are repressed at various time points after memory formation, providing important clues as to how long-term memories are ... read more

Genetic Mutations Linked to a Form of Blindness

Oct. 1, 2015 — Scientists have identified two naturally occurring genetic mutations in dogs that result in achromatopsia, a form of blindness. One of the most promising avenues for developing a cure, however, is ... read more

Oct. 1, 2015 — White-nose syndrome, an invasive skin infection caused by the Pseudogymnoascus destructans fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene ... read more

Oct. 1, 2015 — As easy as it might seem, seeking new species among cultivated plants could be actually quite tricky. While looking into the undescribed orchid, known at the market as 'Big Pink', ... read more

Oct. 1, 2015 — Recent research showed that silicon (Si) is an important nutrient enhancing the endurability of rice plants, however, what controls on Si availability in soils still remain poorly studied. ... read more

The Ecology of Microbial Invasions

Oct. 1, 2015 — Scientists have described how microbial invasions follow the same general pattern as invasions by plant or animal species. This is a clear example of how the microbiological world follows general ... read more

Using Fruit Fly Larvae, Researchers Capture the Symmetry of Movement

Oct. 1, 2015 — How do our brains allow us to smile and breathe? Scientists have identified a network of neurons in the nerve cords of live fruit fly larvae that are similar in most organisms, including humans. ... read more

Oct. 1, 2015 — The shared patterns of gene expression in the limbs and phallus are generated in part by a common set of noncoding DNA, also called 'elements' or 'enhancers,' which act to control ... read more

Accurate Timing of Migration Prolongs Life Expectancy in Pike

Oct. 1, 2015 — Animal migration is a spectacular phenomenon that has fascinated humans for long. It is widely assumed that appropriate timing of migratory events is crucial for survival, but the causes and ... read more

Oct. 1, 2015 — Scientists have shown, for the first time, what happens when a frog's tongue makes contact with a surface. They discovered similarities to conventional adhesive tape. Like sticky tape, the ... read more
