Research identifies protein that signals flowering in squash plants

...to the translocation stream.” The authors screened nearly one hundred accessions of Cucurbita species to identify one, belonging to the undomesticated squash species Cucurbita moschata, that remained vegetative under LD conditions and flowered only when grown under SD conditions. The authors then used th...

Research shows cord blood comparable to matched bone marrow

...plants. While all bone marrow donors were matched, nearly all cord blood donors were mismatched. The main objective of the research was to compare the results after cord blood and marrow transplantation and provide guidelines to transplant physicians on the selection of the best donor for children with l...

Salty oceans provide early warning for climate change

...an water can’t possibly travel this fast (it takes nearly a century for a parcel of water to move from the South Atlantic to the North Atlantic). Instead the scientists think that energy is transferred through the ocean along a deep pressure wave. “The surge of salt generates a pressure gradient in the ocea...

Alzheimer's disease to quadruple worldwide by 2050

...viving with early-stage disease symptoms. However, nearly all of that decline would be attributable to decreases in those needing costly late-stage disease treatment in 2050. The largest increase in the prevalence of Alzheimer’s will occur in Asia, where 48 percent of the world’s Alzheimer’s cases curren...

Study shows lizard moms dress their children for success

...er and has been studying side-blotched lizards for nearly 20 years. He said the lizards' main predator, the coachwhip snake, is a highly efficient hunter, and the lizards need just the right combination of traits to avoid being eaten. "The females are dressing their progeny for success, because they need...

Women well informed about breast cancer, yet lacking knowledge about current treatments

...tments after surgery.” According to the survey, nearly all respondents were aware of chemotherapy and radiation. However, fewer than one out of four had heard of newer therapies such as aromatase inhibitors or monoclonal antibodies, nor were they informed about their benefits. Doctor-patient dialogu...

Plastic that grows on trees

...x HMF yields upward of 70 percent from glucose and nearly 90 percent from fructose while leaving only traces of acid impurities. To achieve this, they experimented with a novel non-acidic catalytic system containing metal chloride catalysts in a solvent capable of dissolving cellulose. The solvent, calle...

Marine phytoplankton changes form to protect itself from different predators

...titute of Technology. “These changes in form made nearly a 100-fold difference in the alga’s susceptibility to being eaten. It’s certainly surprising that a single-celled organism can chemically sense the presence of nearby consumers, identify those consumers and change in opposing ways depending on which...

Researchers develop buckyballs to fight allergy

...granules containing histamine. They are present in nearly all tissues except blood. When mast cells are activated, inflammatory substances such as histamine, heparin and a number of cytokines are rapidly released into the tissues and blood, promoting an allergic response. The researchers found that the u...

When the rats were given haloperidol before and nearly halfway through the eight-hour period, Yamamoto and his colleagues noted more than a fivefold rise in base levels of glutamate in the substantia nigra, a part of the brain known to play a role in movement disorders such as Huntington's disease. A...

Denlinger and his colleagues found nearly a dozen additional heat-shock proteins that are activated during diapause, a hibernation-like state that insects enter when temperatures drop. Insects can stay in this state of arrested development for several months. "We certainly didn't expect t...
