NASA team hacks Opportunity to treat Mars Rover's amnesia

NASA's Mars rover Opportunity has been working well into its golden years - after nearly 11 years roaming the Red Planet, it has survived more than 40 times past its warranty. But now, this trusty veteran explorer is experiencing some worrisome memory loss.

Russian space medic who led Mars experiment dies at 64

Boris Morukov, a Russian cosmonaut and doctor who led an extraordinary experiment in which volunteers simulated a flight to Mars while never leaving a Moscow car park, has died at 64, his scientific institute said Friday.

'Bad luck' of random mutations plays predominant role in cancer, study shows

Scientists from the Johns Hopkins Kimmel Cancer Center have created a statistical model that measures the proportion of cancer incidence, across many tissue types, caused mainly by random mutations that occur when stem cells divide. By their measure, two-thirds of adult cancer incidence across tissues can be explained primarily by "bad luck," when these random mutations occur in genes that can drive cancer growth, while the remaining third are due to environmental factors and inherited genes.

Researchers target the cell's 'biological clock' in promising new therapy to kill cancer cells

Cell biologists at UT Southwestern Medical Center have targeted telomeres with a small molecule called 6-thiodG that takes advantage of the cell's 'biological clock' to kill cancer cells and shrink tumor growth.

Testing anti-drinking drug with help of a fake bar

The tequila sure looks real, so do the beer taps. Inside the hospital at the National Institutes of Health, researchers are testing a possible new treatment to help heavy drinkers cut back—using a replica of a fully stocked bar.

Findings point to potential approach to treat EV-D68 virus causing illness, possible paralysis

New research findings point toward a class of compounds that could be effective in combating infections caused by enterovirus D68, which has stricken children with serious respiratory infections and might be associated with polio-like symptoms in the United States and elsewhere.

Fat isn't all bad: Skin adipocytes help protect against infections

When it comes to skin infections, a healthy and robust immune response may depend greatly upon what lies beneath. In a new paper published in the January 2, 2015 issue of Science, researchers at the University of California, San Diego School of Medicine report the surprising discovery that fat cells below the skin help protect us from bacteria.

Explained: The enigmatic death of Mrs. Oscar Wilde

For decades, historians of literature have mulled the untimely death that met Constance, the wife of the exuberant, scandalous writer Oscar Wilde.

Not all obese people develop metabolic problems linked to excess weight

New research demonstrates that obesity does not always go hand in hand with metabolic changes in the body that can lead to diabetes, heart disease and stroke.

New version of common antibiotic could eliminate risk of hearing loss

On Christmas Eve, 2002, Bryce Faber was diagnosed with a deadly cancer called neuroblastoma. The 2-year-old's treatment, which, in addition to surgery, included massive amounts of radiation followed by even more massive amounts of antibiotics, no doubt saved his life. But those same mega-doses of antibiotics, while staving off infections in his immunosuppressed body, caused a permanent side effect: deafness.

Predicting superbugs' countermoves to new drugs

With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades—such as pneumonia or urinary tract infections—are proving trickier to treat with standard antibiotics.

HIV vaccines should avoid viral target cells, primate model study suggests

Vaccines designed to protect against HIV can backfire and lead to increased rates of infection. This unfortunate effect has been seen in more than one vaccine clinical trial.

Cancer, heart disease, stroke deaths down, life span stays put

Heart disease and cancer, which cause of deaths of half of Americans who die each year, continued to loosen their deadly grip in 2013, while rates of deaths attributed to flu and pneumonia surged, the Centers for Disease Control & Prevention said this week.

Stereotactic body radiation therapy plus chemotherapy improves survival among stage 4 lung cancer patients

A clinical trial that combined stereotactic body radiation therapy with a specific chemotherapy regimen more than doubled survival rates for certain stage 4 lung cancer patients, UT Southwestern Medical Center cancer researchers report.

Discovery of mutated gene in dogs could help treat blindness

A Finnish-North American collaboration of scientists at Michigan State University and the University of Helsinki has found a MERTK gene defect responsible for a recently identified form of progressive retinal atrophy in Swedish vallhund dogs. This discovery opens the door to the development of therapies for diseases that cause blindness both in dogs and humans. The research findings were published in the paper A Novel Canine Retinopathy Associated with MERTK in the journal PLoS ONE in December.
