Here’s the Skinny on Painless Vaccines
Using hair follicles as portals, scientists have delivered DNA vaccines
directly—and painlessly—into the skin.
Fewer gallstones arise in active
women
Sedentary women are more likely to require gallbladder surgery than active
women are.
Is there a super way to make black
holes?
New observations support the notion that before forming a black hole, some
massive stars first explode as supernovas.
Molecular motors spin slowly but surely
The first molecular motors built from scratch spin when powered by light
or chemical energy.
When the other half gets really cold
Four years after the creation of the first Bose-Einstein condensate—an
odd form of ultracold matter composed of atoms called bosons—physicists
have cooled fermions, the other type of atoms, sufficiently to make their
quantum mechanical nature apparent.
Oranges juice up cancer protection
Orange-juice supplementation cut tumor incidence in an animal study of
carcinogen-induced colon cancer.
Ear implants resound in deaf cats’ brains
Experiments with deaf kittens indicate that the brain’s malleability
during childhood accounts for hearing improvements sparked by cochlear
implants in people.
A benefit from ovary removal
Women at high risk of getting breast cancer may lessen that risk by having
their ovaries removed.
Lost Space
Rising din threatens radio astronomy
As more and more services flood the radio spectrum, radio astronomers fear
they’re losing their rarefied view of the universe.
The Science of Big, Weird Flowers
Some of the best things in botany come in large packages
Scientists are scrutinizing various types of stinking flowers that measure
several feet across to better classify and preserve them.
Biomedicine
Wild rats have hepatitis E history
In an effort to figure out how people contract hepatitis E, researchers
have found that more than 80 percent of U.S. wild rats might carry
antibodies to the virus.
Tissue recipients are free of pig virus
None of 160 humans treated surgically with pig tissue during the past 12
years was infected with porcine endogenous retrovirus, or PERV, which all
pigs carry.
Aspirin limits drug-caused deafness
Giving regular aspirin to patients taking certain antibiotics may ward off
the hearing loss that the drugs sometimes cause, according to a study in
guinea pigs.
Thick blood may signal stroke risk
People whose blood clots readily have higher concentrations of several
compounds involved in blood clotting and are more likely to suffer a
stroke than are people whose blood clots less easily.
Hold your breath: Lung cancer screens?
A computed-tomography imaging device may be more effective than X rays in
lowering the high death toll of lung cancer by detecting cancer before it
spreads.
Chemistry
Treatment makes cotton permanent-fresh
A simple and inexpensive treatment creates antimicrobial fabrics for
hospital gowns, towels, bandages, and sportswear.
Vanishing ink could bolster recycling
An erasable printer ink could provide a way to reuse paper several times
before it’s sent to a recycling plant.
Low-fat ice cream can still satisfy
A taste test shows that people like low-fat chocolate ice cream as much as
its full-fat counterpart.
