Smoking Linked to Diabetes Risk

Heavy puffers saw 61% risk increase

(Newser) - The list of ways smoking can kill you got a bit longer today, reports the BBC. Smokers have a 44% higher chance of developing type 2 diabetes, a new study shows, and that risk rises yet higher for heavy smokers, up to 61%. “The relevant question should no longer...

Vaccine for Ovarian Cancer 'Encouraging'

Study shows immune system can seek and kill deadly cells

(Newser) - A new vaccine for ovarian cancer has produced "encouraging" results in primary trials, the BBC reports. Ovarian cancer can be effectively treated with chemotherapy, but 70% of women with the illness die from a recurrence of the cancer within five years of diagnosis. There's "compelling evidence that the...

Legal Assisted Suicide Hasn't Led to Abuse

Study of Oregon, Netherlands finds fears to be unfounded

(Newser) - Fears that legalizing physician-assisted suicide would lead to its use on unwilling, disabled people are unfounded, concludes a new study conducted in Oregon and the Netherlands, where the practice is legal. Researchers scoured hundreds of cases for any kind of bias, finding, “no evidence to justify the grave and...

Testosterone in Womb Linked to Autistic Traits

Supports theory that problem is 'extreme male brain' disorder

(Newser) - An eight-year study has found a link between high levels of fetal testosterone and autistic traits in children, reports the BBC. Scientists don't know whether the testosterone causes the autistic tendencies or if the hormone is a by-product of autism, but the findings appear to support the head researcher's theory...

Has Wiki Replaced the College Library?

Not quite: Undergrads still turn to more traditional sources

(Newser) - Contrary to expectations, college students are not rushing online for answers to research assignments. A new survey shows only 3% of undergraduates with research tasks went to Wikipedia first and only 13% tried search engines. The largest number, 40%,  turned to course materials first and 23% sought out the...

Drinking Coffee May Fight Colon Cancer

Japanese study finds benefits of 3 cups a day apply only to women

(Newser) - Drinking three or more cups of coffee a day can cut the risk of colon cancer in half—but the benefit manifests itself only in women. What's more, Reuters reports, the research was conducted in Japan, where men drink and smoke so much that scientists had trouble controlling for those...

'Caffeinated' Workout May Cut Cancer

Combo of exercise and coffee can fight skin cancer

(Newser) - New research suggests that drinking coffee, combined with regular exercise, speeds up the killing off of cells damaged by ultraviolet-B radiation. Researchers at Rutgers University specifically examined UVB apoptosis — the programmed death of cells that become damaged by ultraviolet rays – in hairless mice. This sort of cell-suicide helps...

No Tired Explanation: Yawning May Cool Brain

Evolutionary adaptation keeps the nervous system's motherboard cool

(Newser) - Yawning may be less a response to boredom than a natural mechanism for cooling off overheated brains, new research says. The human brain operates optimally when cool, much like a computer, and conditions like fatigue actually cause the organ to heat up, ABC News reports. A quick gulp of air...

Heaven Can Wait, and So Must Research

Scholars chafe at temporary closing of Vatican Library

(Newser) - Despite rumblings from anxious researchers, the Vatican Library has closed its doors for at least 3 years to undergo renovations after an inspection this year revealed that the structure couldn’t support the weight of its books. Reading rooms were unusually full last week, the BBC reports, as researchers got...

Don't I Know You? Plants Can Tell Siblings From Strangers

Flora share resources with nearby kin

(Newser) - Plants are smarter than people think: New research shows flora can distinguish between members of their own family and unrelated vegetation, Nature reports. Plants tend to share resources more equitably with nearby siblings by developing smaller root systems, but compete for available nutrients when neighbors are strangers. "Plants have...

Stem Cell Breakthrough Spares Embryos

Technique sidesteps both ethical and technical difficulties

(Newser) - Normal skin cells can be transformed into the equivalent of stem cells in mice, researchers report, and the new technique may revolutionize research on humans. Because it doesn't involve embryos or eggs, the process skirts the ethical quagmires surrounding human stem cell research; the easy availability of raw material and...

Gates Gives $105 Mil to Track Global Public Health

UW center will eye effectiveness of giving

(Newser) - The Bill and Melinda Gates Foundation has given $105 million to the  University of Washington to study the effectiveness of public health programs around the world. The money will be used to create a center to track such measures as child mortality, the prevalence of major diseases  and the availability...

Scientists ID New Breast Cancer Genes

Biggest breakthrough in a decade may advance prevention, treatment

(Newser) - Four newly discovered genes can increase a woman's chance of developing breast cancer by as much as 60%, say scientists who hail the isolation of the genes as the biggest advance in the field since 1994. The breakthrough raises hopes for more advanced treatment and even prevention of breast cancer...

NIH Won't Breed Chimps for Research

Agency cites financial reasons; rights activists thrilled anyway

(Newser) - The National Institutes of Health will stop breeding chimpanzees for use in medical testing, the agency announced yesterday. The practice is being abandoned for financial reasons, NIH says; because chimpanzees live upwards of 50 years in captivity, their lifelong upkeep costs $500,000.

Britain OKs Human-Animal Hybrids for Research

(Newser) - The British government has reversed its stance on the creation of human-animal hybrid embryos and will propose allowing scientists to use them as sources of stem cells. Scientists developing treatments for incurable diseases would be allowed to grow the hybrid embryos for no longer than two weeks, and implanting them...

Bald Take Note: Mice Grow New Hair Follicles

(Newser) - In what could lead to a cure for baldness, scientists have discovered a technique for regrowing hair in an adult mammal for the first time. University of Pennsylvania researchers suceded in stimulating the growth of new skin complete with hair follicles in mice, the Sydney Morning Herald reports.

Researchers Link Gene, Heart Disease

Common variation dramatically increases risk

(Newser) - A gene that can more than double the risk of heart disease, especially in relatively young people, is present in about half of those of European descent, researchers say. The discovery, reported this week, raises hopes of more accurate genetic testing for heart disease—the world's leading cause of death—...

Researchers Fight Fat With Baby Formula

Introducing hormone in infancy trims down rats, sparks controversy

(Newser) - The battle to keep pounds off may start with a baby bottle, say a team of British scientists who found that feeding large doses of the appetite-controlling hormone leptin to baby rats led to svelte adult rats. If those results translate to humans, a baby formula that chemically alters metabolism...

British Scientists Find Fat Gene

Answer to the waistline gap may be in the chromosomes, researchers say

(Newser) - British scientists have for the first time identified a gene that contributes to garden-variety obesity, supporting ancient anecdotal evidence that birthright, not just lifestyle, shapes stomachs.  Although they can't say exactly how the gene, called FTO, works, the 16% of white Europeans carrying two "fat" variations of it...

Bacteria Battle Depression

Research shows brain produces serotonin as an immune response

(Newser) - Clinical depression may be treatable with bacteria, doctors at Bristol University posit. They got the idea when they observed lung cancer patients inoculated with harmless Mycobacterium vaccae who showed reduced symptoms and improved mental health. The brain produces serotonin as an immune response, the docs hypothesized, raising the low serotonin...
