A new jump start for aging blood vessels

...tion of blood pressure. Second, blocking TNFa via chronic etanercept treatment decreased cell death in aged vessels, demonstrating that increased TNFa levels likely contribute to age-related cardiovascular disease. Similar cell-protective effects were found when anti-TNFa antibodies were used in cel...

Leptin has powerful effect on reward center in the brain

...he researchers demonstrated that leptin signaling, via its receptor, occurs in the dopamine neurons in the VTA and that it results in decreased activity of these neurons. "Metabolic control over dopamine neuron function in the VTA is likely to have consequences for a broad range of behaviors and assoc...

New angiogenesis finding may help fight cancer growth

...a new peptide that clearly suppresses angiogenesis via a novel multi-component mechanism," he says. "A key question is whether we can exploit it to develop therapeutics."...

Fire ants: Their true story told by the scientist who loves them

...uth American native that invaded the U.S. Sun Belt via 1940s Mobile, Ala., is known in biology circles as Solenopsis invicta and everywhere else as a painful pest in the grass, so to speak. Then there's Walter R. Tschinkel. An ardent fire ant fan and one of its foremost researchers for more than 30 yea...

Surprising symbiosis: Glassy-winged sharpshooter eats with friends

...B. cicadellinicola's genome from material gathered via dissections of hundreds of insects. The scientists were dumbstruck to find no evidence of the biochemical pathways needed to synthesize amino acids. Could the plant be somehow providing amino acids to its insect predator? Unlikely. Was the sharpshoot...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...r killing activity compared to antibodies produced via conventional methods. "While that earlier research was done with chimeric chickens, it demonstrated the enormous opportunities that transgenic chickens hold as a therapeutics production system," said Robert Kay, Ph.D. Origen Therapeutics president a...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...the prairie and the atmosphere. Ham collects data via a mini-network of six meteorological towers on the Konza Prairie and the Rannells Flint Hills Prairie Preserve. The Konza towers are a component of the regional network, Ameriflux. Counterpart networks in Europe, Asia and Oceania also collect ecologi...

miRNA-mediated silencing of mRNAs

...the miRNA pathway, targeting transcripts for decay via a deadenylation and decapping reaction. The question of whether miRNAs silence gene expression without affecting mRNA levels has been controversial, and conflicting results have been reported in the literature. Dr. Izaurralde explains that, "Our fin...

Record air pollution above the Arctic

...phere above Svalbard since 1991. Measurements made via the institute's aeroplanes serve the ongoing investigation of the impact of aerosols on the climate. "It is still difficult to estimate, whether this year's data constitute the beginning of a common trend", says Andreas Herber. "We need continued mea...

Corals switch skeleton material as seawater changes

...in the temperature and acidity of our oceans ¬¬-- via global warming and rising atmospheric CO2 , respectively -- that will presumably have a significant impact on corals' ability to build their skeletons and construct their magnificent reefs," he said. Corals are crucial to nearshore tropical ecosyste...

Prion find points way to test for human 'mad cow' disease

...hat cause variant Creutzfeldt-Jakob disease (vCJD) via blood transfusions and organ transplants, the scientists suggest. Done in hamsters, the experiments are the first ever to biochemically detect the malformed proteins during the "silent phase" of the disease--just weeks after the animals were infecte...

One-dimensional diffusion accelerates molecular motors

...able to show that the protein reaches the position via a random, one-dimensional diffusion movement along the microtubule, until it locks into place at its end (Nature, May 4, 2006). This discovery is important for understanding cellular life processes like cell division and nerve cell growth. When cell...

Harmful Algal Blooms monitored from space in Chile

...recasts of potential HABs to aquaculture companies via a customised Internet portal. HABs are a natural phenomenon that have increased in frequency over the last 30 years, causing millions of Euros worth of annual losses to the 360 fish farms found in the southern region of Chile. They deplete the conc...
