Light wine intake is associated with longer life expectancy in men

... Average alcohol consumption rose and then fell at various points during the study. Users?consumption was eight grams a day in 1960, then survivors?consumption was 18 grams a day in 1985, dropping to 13 grams per day in 2000. The percentage of wine users increased during follow-up from 2 percent in 1960 to...

Dig deeper to find Martian life

...ers?(GRL), maps out the cosmic radiation levels at various depths, taking into account different surface conditions on Mars, and shows that the best place to look for living cells is within the ice at Elysium, the location of the newly discovered frozen sea on Mars. The lead author, Lewis Dartnell, UCL C...

New fMRI technology making brain tumor surgery safer

... facility owned by Set Shababian, M.D. “We perform various language, motor and vision tasks with the patient in the MRI scanner,?Dr. Leach explained. FMRI scanning takes approximately 75 minutes, about 30 minutes longer than traditional MRI. The DTI scan, which takes five minutes, is performed in the same...

Salmonella survives better in stomach due to altered DNA

...tious. To examine how DT104 behaves to survive various "extreme" conditions, the switching on and off of 500 genetic characteristics was studied. This happened under different conditions such as in a hot, acid or oxygen-free environment. Almost all of the survival characteristics were found to be active ...

Researchers show that veins stiffen as we age

...ampus. While each subject lay resting on a gurney, various gauges, connected to computers, were placed on their arms and legs. An arterial cuff was attached to an upper arm to monitor blood pressure, and venous cuffs were placed around the upper thigh and upper arm to measure the blood flow to the limbs. A...

Microbes compete with animals for food by making it stink

...the traps confirmed the level of attraction to the various forms of the bait, but it didn't necessarily test ...crobe-laden menhaden. Then researchers extracted various compounds from the microbe-laden bait to test whether chemicals produced by the microbes were indeed...

Gladstone investigators identify a new protective action for the powerful anti-HIV factor, APOBEC3G

Penn researcher shows that DNA gets kinky easily at the nanoscale

... colleagues measured the energies required to make various bends in DNA at lengths of five to 50 nanometers --- about a thousand times smaller than the diameter of a typical human cell. ''We found that DNA has different apparent properties when probed at short lengths than the entire molecule does when tak...

Living view in animals shows how cells decide to make proteins

... how exons are erroneously included or excluded in various disease processes," Bonano said. For example, a cell’s decision to include exon IIIb is critical because the exon’s presence or absence determines which variant of the FGFR2 protein is produced, she said. Such subtle variations in proteins can al...

Chronic jet-lag conditions hasten death in aged mice

...t the young mice generally survived well under the various conditions. In contrast, the light-cycle shifts had a marked effect on the survivorship of the old mice. While 83% of old mice survived under the normal schedule, 68% survived under the backward-shift regimen and 47% survived under the forward-shift ...

Stem cells engage in dialogue with the cells that regulate their futures

...the cell to travel to the cell nucleus and turn on various genes. According to Ruohula-Baker, the Notch pathway plays an important role in many stem-cell niches, including those in the blood system, gut, breasts, and muscles. However, in many cases it hasn't been clear which cells send and which ones rece...

New brain-chemistry differences found in depressed women

..., and their relationship to patients' responses to various depression treatments, is crucial to the continued improvement in the understanding of depression and the development of better treatment strategies for patients," Zubieta says. ...

NHGRI aims to make DNA sequencing faster, more cost effective

... circuit techniques that amplify and isolate their various electrical signals. This group will also design a dipole-sensing methodology, which in principle can distinguish signals from each of the DNA bases. Arrays of nanopores will be constructed on silicon substrates using a self-aligned compositional appr...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...u. This has been shown to protect animals against various strains of flu, and could offer protection against the full range of influenza A infections, including H5N1 and any new pandemic or epidemic strains infecting humans. The 'protecting virus' provides instant protection, and completely prevents flu sym...

Newts which regrow their hearts

...of heart muscle cells - the heavy myosin chain and various troponins - were dramatically down-regulated in this process. At the same time, the cells embark on massive cell division to build up new heart muscle. It takes around two weeks for the heart function to be restored in the newt. The data shows that a...
