Biologists report that by evolving a morphological shield to protect their genitalia from males’ forceful copulatory attempts, females of an Asian species of water strider seem to “win” the evolutionary arms race between the sexes. Instead, females only expose their genitalia for copulation after males produce a courtship “song” by tapping the water surface.

When mothers become infected with influenza during their pregnancy, it may increase the risk for schizophrenia in their offspring. Influenza is a very common virus and so there has been substantial concern about this association. A new study suggests that the observed association depends upon a pre-existing vulnerability in the fetus.

The chance discovery last month of a rare radio supernova — an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes — underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. Robotic telescopes and dedicated satellites now search the sky for exploding [...]

Botox is well known for its cosmetic uses, but researchers have now found that it can also significantly improve people’s quality of life if they suffer from another problem that increases with age, an overactive bladder.
The development of blood from stem cell to fully formed blood cell follows a genetically determined program. When it works properly, blood formation stops when it reaches maturity. But when it doesn’t, genetic mutations can prevent the stop signal and cause the developing cells to turn cancerous. Now scientists show for the first time that [...]

The naturalistic respiratory muscle training with high resistance wind instruments may potentially reduce musicians’ risk for obstructive sleep apnea, according to new research.
It’s conventional wisdom in atmospheric science circles: Large raindrops fall faster than smaller drops because they’re bigger and heavier. And no raindrop can fall faster than its “terminal speed.” Now a team of physicists has determined that it ain’t necessarily so.
Four suspects often found at the scene of the crime in cancer are guilty of the initiation and progression of breast cancer in mice that are resistant to the disease, a team led by scientists have found.

Scientists have developed a new type of fish-shaped, bionic robot as an alternative means of marine propulsion that might replace ships’ screws in sensitive waters.

As stroma — the supportive framework of the prostate gland — react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves, said researchers.
