Envisat captures first image of Sargassum from space

..., enabling the solution of massively complex tasks beyond the capabilities of a single machine or local network. By using Grid technology, Gower and King intend to compute 5-years worth of MERIS data to determine global estimates of Sargassum biomass and its contribution to ocean productivity. "So far, ...

Undergraduate research shows leaderless honeybee organizing

... Charlotte senior biology major Andrew Pierce went beyond the textbooks and uncovered something previously unknown. Pierce’s discovery has to do with detecting a significant new detail concerning the behavior of the European honeybee – perhaps the most studied and economically important insect on Earth. Be...

Turn-ons and turn-offs for neurons

...equences, a process called epigenetics ("above and beyond the gene”). Switching gene expression “on” and “off” is of utmost importance when studying gene function in the adult nervous system. In the early 1990s, scientists described a tetracycline-controlled gene expression systems (Tet systems), which a...

Putting feelings into words produces therapeutic effects in the brain

...ting the person to talk or write may have benefits beyond whatever actual insights are gained. These effects are likely to be modest, however, Lieberman said. “We typically think of language processing in the left side of the brain; however, this effect was occurring only in this one region, on the right...

How plague-causing bacteria disarm host defense

...portant role in disabling the body's immune system beyond its previously known role of disrupting the host cell's normal structure, which interferes with the cell's innate ability to engulf and destroy invading bacteria. "The question now becomes, why is Gaq targeted by YpkA"" ...

Arctic ice retreating more quickly than computer models project

... projected timeframe of any time from 2050 to well beyond 2100. The authors speculate that the computer models may fail to capture the full impact of increased carbon dioxide and other greenhouse gases in the atmosphere. Whereas the models indicate that about half of the ice loss from 1979 to 2006 was du...

Mice with a migraine show signs of brain damage

... treat a migraine, you treat the pain. We’re going beyond that. Migraines could be dangerous. The focus should be on prevention,?said Nedergaard, who notes that by the time a person feels pain or notices a visual disturbance, the changes to the brain are already well underway. To make the finding, the te...

Catching cancer's spread by watching hemoglobin

...pshots of blood flow in individual vessels. Moving beyond mere imaging, the technique can detect the difference between oxygen-carrying hemoglobin (oxyhemoglobin) and oxygen-lacking hemoglobin (deoxyhemoglobin). This is important for monitoring tumors, because the oxygenation state around cancerous tissue a...

The longest carbon nanotubes you've ever seen

...ared to predecessors--the longest is 3 millimeters beyond the prior world record. More important for manufacturing, the research team grew a 12-millimeters-thick, uniform carpet of aligned carbon nanotubes on a roughly 10-centimeter silicon substrate, opening the door for scaling-up the process. The inve...

From the deep -- Researchers find new species of sea anemone

...ergy." Daly doesn't know much about A. pearseae beyond its physical description. She and Gusmão aren't sure how old the creatures are, and say that sea anemones can live for hundreds of years. Nor are they sure how A. pearseae reproduce (each anemone may have male and female sex organs), or if it lives e...

Herpes infection may be symbiotic, help beat back some bacteria

... benefits from viral infections that live in areas beyond epithelial surfaces like the skin, throat or intestines. For the new research, Virgin's group worked with strains of mouse herpes virus closely related to human Epstein-Barr virus, Kaposi's sarcoma-associated herpes virus and cytomegalovirus. Dur...

First demonstration of new hair follicle generation in an animal model

...air loss and hair overgrowth. These findings go beyond just a possible treatment for male-pattern baldness. If researchers can effectively control hair growth, then they could potentially find cures for people with hair and scalp disorders, such as scarring alopecia where the skin scars, and hair overgro...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

... law decrees that it cannot damage the environment beyond its boundaries. While studies of proposed undersea manganese mining in the equatorial region of the Pacific found the risks to outweigh the benefits, says Halfar, there have been no independent impact assessment studies of the proposed massive sul...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

...rostate cancer ?defined as disease that has spread beyond the prostate ?and beta-carotene, another antioxidant found in many vegetables and commonly used as a dietary supplement. This unexpected observation "may be due to chance, however beta carotene is already known to increase risk of lung cancer and ...

Cornell lab confirms deadly fish virus spreading to new species

...rts," said Bowser. "The ability of the virus to go beyond a carrier state and cause disease in this important aquaculture species is a major research question we plan to investigate this year."...

Individuals and populations differ in gene activity levels, not just genes

...y. "We looked at what's happening inside the body, beyond what's hard-wired into the genes." Scientists have known for many years about genetic variation, in which individual letters in the genetic code change between individuals and between different populations. However, this study is one of the first...

Deconstructing brain wiring, one neuron at a time

... virus is marooned inside a cell, unable to spread beyond it. However, supplying the missing gene in that same cell allows the virus to spread to cells that are directly connected to it. Since these neighboring cells lack the gene supplied in the first cell, the virus is stuck. Only the cells connected dire...

UCLA study uncovers clues for why Graves' disease attacks the eyes

... and how the receptor enables the cells to survive beyond their normal lifespan. The team plans to develop an antibody drug to block the receptor from interacting with the T-cells and slow down the disease. In Graves?disease, the thyroid gland goes into overdrive, producing excess levels of hormone th...

Sandia researchers take new approach to studying how cells respond to pathogens

...ls developed under this project have applicability beyond infectious disease research. These technologies can also be used for studying cellular signaling involved in diseases such as cancer or by pharmaceutical companies for biomarker discovery. ...

Action video games sharpen vision 20 percent

...ally play, but also beyond—the part of your vision beyond the monitor. The students' vision improved in the center and at the periphery where they had not been "trained." That suggests that people with visual deficits, such as amblyopic patients, may also be able to gain an increase in their visual acuity w...
