Birds can tune in to classics like Vivaldi’s “Concert in D Major,” Miles Davis’s “Blue and Green,” and Led Zepplin’s “Kasmir.” They may also hear songs about the winged life like “Marching J...

Blood test may help signal tumor's remission, return in throat cancer patients

...t can simultaneously analyze the concentrations of each protein, only a small amount of blood was required for the test. The majority of the patients had a complete response to therapy. Patients whose blood levels of these cytokines and growth factors dropped and remained low following treatment were ...

Releasing fish for the future

...nd 50% of the total recreational catch is released each year in Australia. This amounts to more than 47 million fish being caught and released annually. New research is now seeking to maximise the post-release survival of other commonly-caught species including luderick, sand mullet, garfish, tailor, A...

Math that powers spam filters used to understand how brain learns to move our muscles

...idea as applied to the workings of a brain is that each brain uses what it already knows to “predict” or “believe” that something new will happen, then uses that information to help make it so. “We used the idea that prior experience and belief affect the probability of future outcomes, such as taking ...

The insect vector always bites twice

...ss specifically the degree of exposure to bites of each of these species. Starting from immunogenic salivary proteins, simple and effective prevention tools (immuno-tests) can be devised to assess the exposure of human subjects, or be used in endemic areas to evaluate the efficacy of existing vector co...

Dirty snow may warm Arctic as much as greenhouse gases

...would leave snow brighter, he says. New snow falls each year, and if it contained fewer impurities, the ground would brighten and temperatures would cool. Carbon dioxide lives in the atmosphere for a century, so cutting back on emissions can prevent further warming but does not produce immediate cooling....

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...deaths out of 300 million acute cases of infection each year. Most of these deaths occur in young children living in sub-Saharan Africa. Roepe and his collaborators at Georgetown University, in collaboration with investigators at the National Institutes of Health, described in 2000 that the PfCRT gene...

Loss of stem cells correlates with premature aging in animal study

..., a deterioration of pools of cells that reside in each tissue type,” says Brown. We accelerated the aging process by wiping out a large fraction of these cells prematurely, in one fell swoop. Essentially, these mice start their young adulthood with two strikes against them in terms of long-term tissue ma...

...henobarbital) that costs less than $3 (£1.5; €2.2) each year. The World Health Organisation recommends phenobarbital as the treatment of choice in resource restricted countries, but this policy has been questioned because of concerns about adverse behavioural effects, particularly in children.

Physicist cracks women's random but always lucky choice of X chromosome

...to gather around both of the XIST suicide genes on each X Chromosome. This starts a race between the two build ups of protein. Inevitably one of these two nascent protein plugs narrowly wins that race and reaches an energy state in which it can pull together all the material building up in both plugs into...
