New study finds genetically engineered crops could play a role in sustainable agriculture

... understanding of a complex issue. The project is enhanced by the creation of a public database, Nontarget Effects of Bt Crops, developed by NCEAS ecoinformatics expert, Jim Regetz, that will allow other scientists to conduct congruent analyses.” ...

Herpes virus hijacks DNA repair process

...that sometimes play multiple roles. To ensure that enhanced viral replication wasn't linked to orf36's interactions with other molecules, researchers turned to mice lacking the genes for ATM and H2AX, the damage response proteins activated by infection. When they infected cells from these mice with murine her...

Marine phytoplankton changes form to protect itself from different predators

...s by 60 to 90 percent, while signals from ciliates enhanced colony formation by more than 25 percent. The transformations took place over periods of three to six days, and the overall size difference could be dramatic. “When one of these cells changes to the biggest colony form, although it takes a while,...

Master regulatory gene of epithelial stem cells identified

...to show that p63’s key function was to provide the enhanced potential of stem cells to divide. "The fact that p63 is essential for these epithelial stem cells, while other master regulators have been identified for blood stem cells and spermatocyte stem cells, suggests a fundamental requirement for tissu...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...with HIV-1 by about 95 percent, the RC-111 variant enhanced viral infection five-fold. There are three structural varieties of peptides, also known as defensins ?alpha, beta and theta, Lehrer said. Humans have only alpha and beta; monkeys have all three. "Here's a peptide whose normal structure allows ...

Dealing deadly cancers a knockout punch

...treated with both agents, test animals experienced enhanced tumor regression compared with either agent alone, and without additional toxicity. Oncolytics has permission from the U.K. regulatory authorities to test Reolysin in three separate human trials in combination with the cancer drugs gemcitabine, pacli...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...on of over 20 specialized structures that may have enhanced the hearing of various fish species during their evolution (2aAB1), and the notable features of 36 cat species' middle ears, which may provide clues on the evolutionary pressures on them (2aAB4). LISTENING TO MUSCLE NOISE Muscles make noise. ...

Fused nasal bones helped tyrannosaurids dismember prey

...y Rayfield of Bristol hypothesized that the fusion enhanced the skull strength. Now we know it did." ...

To sleep, perchance to dream: New insight into melatonin production

...ly, melatonin production is inhibited by light and enhanced by darkness, usually peaking in the middle of the night. Melatonin's expression pattern is mimicked by a protein called AANAT, which is a key enzyme in the melatonin biosynthesis pathway. Dr. Kim and colleagues uncovered the mechanism of rhythmi...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

...rs also noticed something unexpected. The vaccine enhanced another type of immune response known as cellular-mediated immunity (CMI). CMI allows the immune system to identify, target and kill cells that have already become infected, something antibodies can not do. The determine the cause of this effect,...

Jefferson scientists find rabies-based vaccine could be effective against HIV

...two different immune system boosts, but didn’t see enhanced immune responses. They then developed a new vector, a viral surface protein from another virus, vesicular stomatitis virus (VSV). Two years after the initial immunization, they gave a booster vaccine with the rabies-VSV vector, and saw SIV/HIV-specif...

Mutation improves memory, may lead to memory-enhancing pill

A mind-altering mutation in mice results in an enhanced long-term memory, researchers report in the April ...spect that decreasing the phosphorylation of eIF2a enhanced memory storage,?Costa-Mattioli said. In an effort to validate their earlier findings, the researc...

Human's ecological footprint in 2015 and Amazonia revealed

...lateral damage to the surrounding forests ?through enhanced drying of the forest floor, increased frequency of fires, and lowered productivity. The loss of healthy forests can degrade key ecosystem services, such as carbon storage in biomass and soils, the regulation of water balance and river flow, the modu...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...s a demonstration that stem cell efficacy could be enhanced even without the need for genetic engineering. (The drug, a glycosphingolipid biosynthesis inhibitor, is in a class of compounds called "substrate reduction therapy" drugs.) This part of the study not only represented the first "multidisciplinary" us...

Massive coral death attributed to earthquake

...they need to prosper. The recovery process will be enhanced by management that encourages sustainable uses of these ecosystems and the protection of critical habitats and species to help this process." ...

Common gene version optimizes thinking -- but with a possible downside

...phrenia," added Daniel Weinberger, M.D. "Normally, enhanced cortex connectivity with the striatum would provide increased flexibility, working memory capacity and executive control. But if other genes and environmental events conspire to render the cortex incapable of handling such information, it could backf...

A rarity among arachnids, whip spiders have a sociable family life

...at benefits of whip spider social behavior include enhanced safety from predators. Although there are few reports of other creatures eating them, a mother nearby may offer young amblypygids some protection. When Rayor disturbed D. diadema youngsters, they gathered closer to each other or their mother. Now a...

Shedding new light on proteorhodopsin

...the amount of light that can be collected in cells enhanced with proteorhodopsin. For this the researchers will need to identify the most efficient forms of the protein, then manipulate microbial genomes through the addition or deletion of key genes. ...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...lowing the researchers to compare how training had enhanced the brain's ability to process car shapes. They fo... suggests how the learning of visual skills can be enhanced by directly monitoring neuronal activity. "This could be useful, for instance, to speed up learning ...

Canadian study shows bilingualism has protective effect in delaying onset of dementia by four years

...n later years of life. Cognitive reserve refers to enhanced neural plasticity, compensatory use of alternative brain regions, and enriched brain vasculature, all of which are thought to provide a general protective function against the onset of dementia symptoms. Now scientists with the Rotman Research In...
