Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
Approved in 2012, Brazil's new Forest Code has few admirers. Agricultural interests argue that it threatens the livelihoods of farmers. Environmentalists counter that it imperils millions of hectares of forest, threatening to release the billions of tons of carbon they contain. A new study, co-authored by Woods Hole Research Center (WHRC) scientists Michael Coe, Marcia Macedo and Brazilian colleagues, published this week in Science, aims to clarify the new law. Entitled "Cracking Brazil's Forest Code," the article is the first to quantify the implications of recent changes to the Forest Code and identify new opportunities and challenges for conservation.
Washington, DC (April 24, 2014) — Many kidney failure patients in Australia who could benefit from undergoing dialysis at home are being treated in hospitals and dialysis units, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). This is creating significant costs for healthcare providers and causing unnecessary disruptions to patients' lives.
If you really care about the climate, you can stop filling out surveys and complaining about what people believe and do something more meaningful than buy carbon credits - you can give up meat.
And 11 other things that can separate you from the pack that are more interested in uniform bans and mitigation. Those won't work. Take the initiative and it doesn't matter what anyone else does.
A new report, Strategies for Mitigating Climate Change in Agriculture by Mitigation 2014, says it can eliminate the climate nosedive that will occur if people continue to eat meat and use air conditionin. It just needs people in richer countries who claim they care about emissions to show it.
A research team lead by Academy Professor Kari Rissanen at the University of Jyväskylä has discovered a new water-soluble fluorescent detection system that is extremely sensitive to pyrophosphate (PPi).
Pyrophosphate has a key role in energy transduction, DNA replication and other metabolic processes that are dysregulated in cancer cells.
The discovery might lead to the development of a method for early detection of cancer cells.
Scientists at the University of Liverpool have been part of a ten-year project which has successfully sequenced the genetic code of the tsetse fly – making major advances in disease control possible.
Tsetse flies are unique to Africa and can infect people bitten by them with sleeping sickness, a disease which damages the nervous system and is fatal if untreated. This kills over 250,000 people each year.
Traditional methods of control such as releasing sterile males, trapping and pesticide spraying are expensive and difficult to implement. Sleeping sickness can also evade the immune system, making a vaccine hard to create, so the genetic information will allow researchers to develop alternative strategies to control the disease.
Modesto, CA (April 25, 2014) - Six new almond-related research studies will be presented next week in San Diego at the American Society of Nutrition (ASN)'s Scientific Sessions and Annual Meeting, held in conjunction with Experimental Biology 2014 (EB). The conference attracts an international audience of approximately 13,000 leading scientists specializing in various health disciplines.
The science presented will reveal new insights on the effects of almond consumption on overall diet quality and health status, abdominal adiposity, measures of appetite and satiety, and cardiovascular risk factors.
A "brown dwarf" star with the catchy name of WISE J085510.83-071442.5 appears to be the coldest of its kind.
When people think of stars, they think of hot fusion plasma bubbling and erupting. WISE J085510.83-071442.5, 7.2 light-years away, making it the fourth closest system to our sun, is instead as frosty as Earth's North Pole.
The locations of the star systems that are closest to the Sun. The year when each star was discovered to be a neighbor of the Sun is indicated. The brown dwarf WISE J085510.83-071442.5 is the fourth nearest system to the Sun. Credit: Janella Williams,
PHILADELPHIA - Sometimes a full-on assault isn't the best approach when dealing with a powerful enemy. A more effective approach, in the long run, may be to target the support system replenishing the supplies that keep your foe strong and ready for battle. A group of researchers from the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania is pursuing this strategy by employing a novel DNA vaccine to kill cancer, not by attacking tumor cells, but targeting the blood vessels that keep them alive. The vaccine also indirectly creates an immune response to the tumor itself, amplifying the attack by a phenomenon called epitope spreading. The results of the study were published this month in the Journal of Clinical Investigation.
An ancient form of meditation and exercise could help women who suffer from urinary incontinence, according to a new study from UC San Francisco.
In a study scheduled to be published on April 25, 2014 in Female Pelvic Medicine & Reconstructive Surgery, the official journal of the American Urogynecologic Society, UCSF researchers discovered that a yoga training program, designed to improve pelvic health, can help women gain more control over their urination and avoid accidental urine leakage.
Mental health diagnoses have become common in children raised in developed nations. Medication is often prescribed to treat the symptoms of these conditions but few population-based studies have examined the use of prescription medication to treat mental health problems among younger as well as older school-aged children (8–10). A new CDC report describes the sociodemographic characteristics of children aged 6–17 years prescribed medication or taking medication during the past 6 months for emotional or behavioral difficulties, and describes parental reports of the perceived benefit of this medication.
A new report in Molecular Systems Biology speculates about how primitive cells learned to synthesize their organic components – the molecules that form RNA, lipids and amino acids. The paper also suggests an order for the sequence of events that led to the origin of life.
A simulated reconstruction of Earth's earliest ocean in the laboratory revealed the spontaneous occurrence of the chemical reactions used by modern cells to synthesize many of the crucial organic molecules of metabolism. Previously, it was assumed that these reactions were carried out in modern cells by metabolic enzymes, highly complex molecular machines that came into existence during the evolution of modern organisms.
A new study finds benefits to consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass.
The researchers from the University of Texas Medical Branch found that using a protein blend of soy, casein and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone.
It also showed a prolonged increase in amino acid net balance across the leg muscle during early post-exercise recovery, suggesting prolonged muscle building.
