Tiny paddle oscillator senses the mass of a virus
... Think of a tiny fly-swatter mounted by its handle like
a diving board. A large array of paddles were mounted on a piezoelectric crystal that can be made to vibrate at frequencies on the order of 5 to 10 megaHertz (mHz). The experimenters then varied the frequency of vibration of the crystal. When it matc...
Link between immune protein and longer survival in melanoma patients identified

CXCR3- a 'homing' feature that allows these killer cells to find and eradicate tumors. "This data may indicate that early melanoma vaccination is essential, and that vaccines inducing specific T cells with tumor-homing ability can make a signif...
Scientists find acid rain an unlikely ally in the battle against a greenhouse gas

those in acid rain, affected methane emissions in ...etlands become warmer. In this way, acid rain acts like
a temporary lid on the largest methane source. Gauci is cautious about t...
Powerful 'toolkit' developed for functional profiling of yeast genes
...laces the original in the new toolkit. "Much like
barcodes identify your purchases at the grocery store, these genetic barcodes identify each of the yeast mutants," says Boeke. "So we can mix the mutants together, challenge them to survive removal of a particular gene, nurture the ones that make it ...
Four new vertebrate fossil finds in Ischigualasto, Argentina
...ds. What makes it unique is a foreshortened skull, like
many later sauropods of the Jurassic and Cretaceous. "This specimen shows the incredible diversification of prosauropods already in the Late Triassic," said Alcober, who has documented four species now from the same Los Colorados Formation. "This gro...
National Eye Institute funds search for genetic key to corneal disease

a fingerprint or be a dense patch blocking out light on the front layer of cells in the cornea," Yee said. "Onset can occur as early as infancy, as late as adolescence, and is accompanied by a sharp, stabbing pain. The spots can be visually debilit...

disease or predation, will evolve to deteriorate more rapidly as they get older. Their predictions have been widely accepted and are supported by some experiments. Now, a study by UC Riverside researchers comparing fish living in high- and low-predat...

...and systems biology models of biological processes like
apoptosis, cell divisions, and others involved in cancer. Two senior research scientists from the Bioinformatics Group, Raoul-Sam Daruwala and Archisman Rudra, collaborated with Mishra to devise the algorithm and create its software implementation. D...

to know if the invasion caused extinctions." Carbonate rocks created in cool waters exist before the invasion, but during the invasion, the rocks were formed in warmer waters. During the Ordovician, the central United States was situated on the equ...

to see Svitanas studies repeated in similar settings to answer further questions. For example, is there a critical buried channel size or depth, or a critical distance away from the major surface water source at which this rapid linkag...
Ancient creature fossilized by the bacteria that ate it
