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.
Hawaii does not get a lot of hurricanes, only two have made landfall in the last 30 years.
But scientists at the International Pacific Research Center, University of Hawaii at Manoa predict that Hawaii could see a two-to-three-fold increase in tropical cyclones by 2075.
How worried should Hawaii residents get?
Bullying and violence are the latest cultural magnet for administrators in schools around the country, but the solution may not be paid commercials, more books or talks in the gym - it may be as simple as embracing team sports again.
At the Pediatric Academic Societies (PAS) annual meeting in Washington, D.C., researchers discussed their analysis of data from the 2011 North Carolina Youth Risk Behavior Survey to see if athletic participation was associated with violence-related behaviors, including fighting, carrying a weapon and being bullied. A representative sample of 1,820 high school students in the state completed the survey, which also asked adolescents whether they played any school-sponsored team sports (e.g., football) or individual sports (e.g. track).
Natural emissions and man-made pollutants have an unexpected effect; they make clouds brighter and have a cooling effect on the world's climate.
A quick primer: Clouds are made of water droplets, condensed on to tiny particles suspended in the air. When the air is humid enough, the particles swell into cloud droplets. It has been known for some decades that the number of these particles and their size control how bright the clouds appear from the top, controlling the efficiency with which clouds scatter sunlight back into space. A major challenge for climate science has been trying to understand and quantify these effects, which have a major impact in polluted regions.
Researchers were able to controll seizures in epileptic mice with a one-time transplantation of medial ganglionic eminence (MGE) cells into the hippocampus, which inhibit signaling in overactive nerve circuits.
Cell therapy has become a focus of epilepsy research, in part because current medications, even when effective, only control symptoms and not underlying causes of the disease, according to Scott C. Baraban, PhD of UC San Francisco, who led the new study. In many types of epilepsy, he said, current drugs have no therapeutic value at all.
Since marijuana is fast becoming legal again in America, it seems strange to be calling cigarettes a 'gateway' to it, but anti-smoking campaigns are almost as large a business as tobacco and so a paper at the Pediatric Academic Societies (PAS) annual meeting in Washington, D.C., today supports the notion that cigarettes are a gateway to marijuana.
And, like everyone who picks a position and then wants data to support it, they used surveys of students. They found that students who smoked marijuana smoked more cigarettes than those who just smoked cigarettes. Cigarettes are so demonized a successful public relations campaign against drugs might be that it leads to more smoking. That will likely work far better than a fried egg in a television commercial.
In the UK, health care is nationalized but a trial lawyer for maternity cases says that has made money a bigger concern in deciding who gets quality medical care.
A report by The Royal College of Obstetricians and Gynaecologists (RCOG) said there was enormous disparity in the quality of care patients received across the country. It looked at the performance of maternity units in England during 2011/12 and found that rates of inductions, emergency cesareans and assisted deliveries were twice as high in some hospitals as others.
We all know time is relative, just like we know that the plates are moving around underneath us, but both time and that the earth is not moving still 'ground' us on a daily basis.
A map of avian influenza (H7N9) risk is now available. The map is comprised of bird migration patterns, and adding in estimations of poultry production and consumption, which are used to infer future risk and to advise on ways to prevent infection.
As of today, there have been 127 confirmed cases of H7N9 in mainland China with 27 deaths. A lack of information about the virus and its mode of transmission has led to public concerns that H7N9 could be a pandemic waiting to happen.
Prenoxad Injection is a pre-filled syringe containing 1mg/ml naloxone hydrochloride solution for injection. Martindale Pharma announced the world's first licensed emergency treatment for acute opioid related overdose for use at home or other non-medical settings.
There are more than 1,000 fatal opioid related overdoses just in the UK each year, with a significant proportion of these being witnessed by other people who use drugs, family members and loved ones.
In America, science is as polarized as politics. Corporate scientists, like at pharmaceutical companies, are criticized for working at unethical companies while academic scientists are criticized for 'chasing funding' rather than helping people.
Like many stereotypes, those images started with a kernel of truth. So if you ask most people if the pharmaceutical industry can self-police its advertising policies, they will reply it is not possible, an outside force must do it. But then if you ask people who are skeptical of medicine, they will say the FDA is also controlled by pharmaceutical companies.
Most countries have an established system for self-regulation of pharmaceuticals advertising.
When you read studies about embryogenesis and the cellular and molecular mechanisms used by cells to assemble into layers or clusters of epithelial cells, you often see the fruit fly Drosophila melanogaster as a model.
Stowers Institute for Medical Research Associate Investigator Matt Gibson, Ph.D., uses a different star, Nematostella vectensis, for his lab's paper on embryology.
Tissues comprised of epithelial cells shape the body not only of simple creatures but also of mammals, where they line every body cavity from lung to intestine and form hormone- and milk-secreting glands. Unfortunately these cells have a dark side too - over 80% of human cancers, carcinomas, are of epithelial origin.
Why did saber-toothed cats, hyenas, an extinct 'bear-dog', ancestors of the red panda and several other carnivores die under unusual circumstances in a Spanish cave near Madrid approximately 10 million years ago?
Different scenarios have been floated for why an unusually large concentration of healthy adult carnivores died in this cave during the Late Miocene, a location known now as Batallones-1 fossil site, Madrid Basin, Spain; accidental falls into the cave, maybe the animals died in other locations and were washed into the cave, everything but mass suicide.
Yet those scenarios would mean mean herbivores also got trapped. And not just healthy adults.
