Children’s eye injuries from nonpowder guns on the rise

Science News Daily - 1 hour 59 min ago
Over 3000 children were treated in U.S. emergency departments in 2012 for eye injuries related to paintball guns, airsoft guns, BB guns and pellet guns, which are popular non-powder guns. A new report analyzes the trends in hospital admissions associated with different types of firearms and suggests regulations that can help prevent serious injuries.

Locusts provide insight into brain response to stimuli, senses

Science News Daily - 2 hours 2 min ago
By training a type of grasshopper to recognize odors, a team of biomedical engineers is learning more about the brain and how it processes information from its senses. While the results of this research focus on the sense of smell, researchers plan to use the results to determine if the brain processes signals similarly for other senses.

Studies yield mixed findings on high-dose flu vaccine for elders

Science News Daily - 3 hours 51 min ago
Is the high-dose version of the flu vaccine more effective than the standard dose for older folks? A new study says yes, but only for the 'oldest old': those 85 or older. For those between ages 65 and 84, the standard vaccine seems to work just as well, researchers report.

Malaria parasite causes red blood cell changes, study suggests

Science News Daily - 3 hours 53 min ago
A model of a malaria-infected red blood cell may lead to better ways to treat malaria, according to a team of engineers and molecular biologists who investigated how this parasite infection causes the red blood cells to stiffen.

Nerve cells, blood vessels in eye 'talk' to prevent disease

Science News Daily - 3 hours 53 min ago
Nerve cells and blood vessels in the eye constantly 'talk' to each other to maintain healthy blood flow and prevent disease, scientists say. The study has implications for treating diseases such as diabetic retinopathy and age-related macular degeneration--the leading causes of vision loss in adults. Since the eye is often a good model for understanding the workings of the brain, the findings also provide clues to major neurological diseases such as Alzheimer's, researchers say.

High-pitched sounds cause seizures in old cats: Certain breeds more susceptible

Science News Daily - 3 hours 53 min ago
Sharp high-pitched sounds have been found to cause seizures in older cats. The most commonly reported triggers were the sound of crinkling tin foil, a metal spoon clanging in a ceramic feeding bowl, chinking or tapping of glass, crinkling of paper or plastic bags, tapping on a computer keyboard or clicking of a mouse, clinking of coins or keys, hammering of a nail and even the clicking of an owner's tongue.

Breakthrough in understanding Canavan disease

Science News Daily - 5 hours 7 min ago
Investigators have settled a long-standing controversy surrounding the molecular basis of an inherited disorder that historically affected Ashkenazi Jews from Eastern Europe but now also arises in other populations of Semitic descent, particularly families from Saudi Arabia. Canavan disease is a type of leukodystrophy that is an incurable and progressively fatal neurological condition.

The monk parakeet: Tracking an invasive bird

Science News Daily - 5 hours 38 min ago
The monk parakeets that have invaded Europe and North America over the last 40-50 years fortifying their massive communal nests atop utility poles in many urban areas appear to have originated from the same small area in South America, according to a new study.

No health drawbacks to veterans' dual use of VA, Medicare Advantage, study says

Science News Daily - 5 hours 38 min ago
In a study that looked at a handful of quality measures for chronic disease care, veterans who used both Veterans Affairs care and a Medicare Advantage plan during 2008 or 2009 did no better or worse than those who relied strictly on VA.

Alternate theory of inhabitation of North America disproven

Science News Daily - 5 hours 39 min ago
The most widely accepted theory of the inhabitation of North America is that humans migrated from Siberia to Alaska by means of a 'land bridge' that spanned the Bering Strait. However, in the 1990s, a small group of researchers proposed that North America was first settled by people from Europe, who moved from east to west via a glacial 'ice bridge.' Now, researchers have definitively disproven the ice bridge theory.

How an RNA gene silences a whole chromosome

Science News Daily - 6 hours 59 min ago
Researchers have discovered how an abundant class of RNA genes, called lncRNAs can regulate key genes. By studying an important lncRNA, called Xist, the scientists identified how this RNA gathers a group of proteins and ultimately prevents women from having an extra functional X-chromosome -- a condition in female embryos that leads to death in early development. These findings mark the first time that researchers have uncovered the mechanism of action for lncRNA genes.

Augmenting a gas naturally in our bodies fights RSV infection

Science News Daily - 6 hours 59 min ago
Hydrogen sulfide, a gas produced naturally within our bodies, reduces the severity of respiratory syncytial virus, or RSV, a new study shows for the first time. When someone has a RSV infection, his or her body is less able to produce the protective hydrogen sulfide. The study found that a drug that triggers a steady release of this gas decreases the virus's ability to multiply and reduces inflammation of the airways.

Researchers train computers to identify gene interactions in human tissues

Science News Daily - 7 hours 42 min ago
Researchers have trained a computer to crunch big biomedical data in order to recognize how genes work together in human tissues. Combining genomic data from 38,000 experiments, this research group has generated functional genetic maps for 144 human tissues types and organs. This big step in the use of large genomic data sets enables great strides in functional human genetics, with important applications for treatment of disease. The findings shed light on genetic interactions that underlie human diseases, the investigators say.

Hate to diet? It's how we're wired

Science News Daily - 7 hours 43 min ago
If you're finding it difficult to stick to a weight-loss diet, scientists say you can likely blame AGRP neurons -- hunger-sensitive cells in your brain. New experiments show these neurons are responsible for the unpleasant feelings of hunger that make snacking irresistible. The negative emotions associated with hunger can make it hard to maintain a diet and lose weight, and these neurons help explain that struggle.

Bizarre 'platypus' dinosaur: Vegetarian relative of T. rex

Science News Daily - 7 hours 43 min ago
Although closely related to the notorious carnivore Tyrannosaurus rex, a new lineage of dinosaur discovered in Chile is proving to be an evolutionary jigsaw puzzle, as it preferred to graze upon plants. Chilesaurus boasted a proportionally small skull, hands with two fingers like Tyrannosaurus rex and feet more akin to primitive long-neck dinosaurs.
