Ocean warming is paradoxically driving bottom-dwelling invertebrates - including sea scallops, blue mussels, surfclams and quahogs that are valuable to the shellfish industry - into warmer waters and threatening their survival, a Rutgers-led study shows.
In a new study published in the journal Nature Climate Change, researchers identify a cause for the "wrong-way" species migrations: warming-induced changes to their spawning times, resulting in the earlier release of larvae that are pushed into warmer waters by ocean currents.
Syracuse, N.Y. - A recent study by sport analytics professors shows the Adjusted Plus-Minus (APM) statistic used to evaluate the performance of NBA players is sometimes misleading because it does not accurately account for the quality of a player's teammates.
NASA-NOAA's Suomi NPP satellite passed over the Philippine Sea on Sept. 4 and provided a visible image of Haishen that had strengthened into a super typhoon.
KNOXVILLE, Tenn. -- More than a century has passed since the last scientific analyses of the famed "Lincoln County [Tennessee] process" was published, but the secrets of the famous Tennessee whiskey flavor are starting to unravel at the University of Tennessee Institute of Agriculture. The latest research promises advancements in the field of flavor science as well as marketing.
Autophagosomes first form as cup-shaped membranes in the cell, which then grow to engulf the cellular material designated for destruction. The formation of these membranes is catalyzed by a complex machinery of proteins. "We have a very good knowledge of the factors involved in autophagosomes formation", explains group leader Sascha Martens, "but how they come together to initiate the formation of these membranes has so far been enigmatic".
Researchers have discovered how a protein in plant roots controls the uptake of minerals and water, a finding which could improve the tolerance of agricultural crops to climate change and reduce the need for chemical fertilisers.
The human ability to digest the milk sugar lactose after infancy spread throughout Central Europe in only a few thousand years. This is the conclusion reached by an international research team led by Johannes Gutenberg University Mainz (JGU). The researchers analyzed genetic material from the bones of individuals who had fallen in a conflict around 1200 B.C. on the banks of the Tollense, a river in the present-day German state of Mecklenburg-Western Pomerania, and report their findings in Current Biology this week.
Organization of cells into specific compartments is critical for their function. For instance, by separating the nucleus from the cytoplasm, the nuclear envelope prevents premature translation of immature RNAs. During mitosis, however, the nuclear envelope disassembles, allowing large cytoplasmic components such as ribosomes to mix with nuclear material. When the nuclear envelope reassembles following mitosis, these cytoplasmic components must once again be removed.
In 2013 the Rim Fire-the largest fire on record in the Sierra Nevada-burned one third of the potential California Spotted Owl (Strix occidentalis occidentalis) habitat in Yosemite National Park. The park provides prime habitat for this Spotted Owl subspecies, which is listed as a Species of Special Concern by the California Department of Fish and Wildlife, and concern grew regarding the fire's effect on Yosemite's owl populations. But recent research provides some good news regarding the park's owls, and it may be due to Yosemite's unique history and fire management strategy.
NASA's Terra satellite's visible image of Typhoon Haishen revealed a small "pinhole" eye surrounded by several hundred miles of thunderstorms spiraling around it as it continued moving north though the Northwestern Pacific Ocean.

NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of former Typhoon Maysak, now an extra-tropical storm. Wind shear continued pushing the bulk of the storm's clouds to the northwest.
Maysak's Landfall
Maysak made landfall on Sept. 2 at 1 p.m. EDT (1700 UTC) about 12 miles west of Busan, South Korea with maximum sustained surface winds of 64 knots (74 mph/119 kph).

Colorectal cancer (CRC) is the third most common cancer among women and men in the USA, and recent studies have shown an increasing incidence in less developed regions, including Sub-Saharan Africa (SSA). A team of researchers from South African universities in collaboration with the University of South Carolina-Upstate, have developed method which relies on a hybrid signature (based on patterns in DNA mutation and RNA expression) and assessed its predictive properties for the mutation status and survival of CRC patients.
Researchers at Texas A&M University have produced a therapeutic derived from turmeric, a spice long-praised for its natural anti-inflammatory properties, that shows promise in decreasing ocular inflammation in dogs suffering from uveitis, an inflammation of the eye that leads to pain and reduced vision.
Uveitis -- a common condition in dogs, humans, and other species -- can have many causes, often occurring secondary to infectious diseases cancer, and autoimmune diseases; it also is found in patients with longstanding cataracts and after operations correcting cataracts.
AMHERST, Mass. - Venus flytraps do it, trap-jaw ants do it, and now materials scientists at the University of Massachusetts Amherst can do it, too - they discovered a way of efficiently converting elastic energy in a spring to kinetic energy for high-acceleration, extreme velocity movements as nature does it.
Researchers at the University of Illinois Chicago have developed a unique method for precisely controlling the deposition of hydrogel, which is made of water-soluble polymers commonly used to support cells in experiments or for therapeutic purposes. Hydrogel mimics the extracellular matrix - the natural environment of cells in the body.
The researchers noticed that their technique - which allows for the encapsulation of a single cell within a minute hydrogel droplet - can be used to coax bone marrow stem cells into specialized cells.
