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.
A new study has pinpointed working memory as a cause of learning difficulties in people with schizophrenia.
Working memory is known to be affected in 1 percent of the population who have schizophrenia, but it has been unclear whether that has a specific role in making learning more difficult, said Brown University postdoctoral researcher Anne Collins, lead author of the paper
in the Journal of Neuroscience.
Though numerous experts and policy makers have called for hospitals to screen patients for methicillin-resistant Staphylococcus aureus (MRSA) infections and isolate anyone testing positive to prevent the spread "Superbugs" in healthcare settings, it's too economically burdensome. Several states have enacted laws requiring patients be screened for MRSA upon admission but two new abstracts, scheduled for presentation on Friday at IDWeek, the annual scientific meeting for infectious disease specialists, found universal MRSA screening and isolation of high-risk patients will help prevent MRSA infections but may be too economically burdensome for an individual hospital to adopt.
Sauropods, large, long-necked plant-eating dinosaurs such as Diplodocus and Brachiosaurus, are the largest animals to have ever walked the Earth, with the biggest weighing 80 tons.
Clearly, a single creature the size of 11 elephants would have needed vast amounts of food. How did multiple sauropod species live alongside one another in prehistoric ecosystems between 210 and 65 million years ago?
New research from the University of Bristol and the Natural History Museum, London details the community of the Late Jurassic Morrison Formation, a distinctive sequence of sedimentary rock in the western United States from which over 10 species of sauropod are known.
Researchers have created a molecule known as a peptide mimic that displays a functionally critical region of the virus that is universally conserved in all known species of Ebola. This new tool can be used as a drug target in the discovery of anti-Ebola agents that are effective against all known strains and likely future strains.
Ebola is a lethal virus that causes severe hemorrhagic fever with a 50 percent to 90 percent mortality rate. There are five known species of the virus. Outbreaks have been occurring with increasing frequency in recent years, and an unprecedented and rapidly expanding Ebola outbreak is currently spreading through several countries in West Africa with devastating consequences.
Using rats as model subjects, scientists have found that adolescents were at an increased risk of suffering negative health effects from sugar-sweetened beverage consumption.
Adolescent rats that freely consumed large quantities of liquid solutions containing sugar or high-fructose corn syrup (HFCS) in concentrations comparable to popular sugar-sweetened beverages experienced memory problems and brain inflammation, according to a new study. Neither adult rats fed the sugary drinks nor adolescent rats who did not consume sugar had the same issues.
Emphasizing weight in health definitions could be harmful to patients, finds an article in the Journal of Obesity.
Dr. Rachel Calogero of the School of Psychology at the University of Kent and colleagues recommend that this approach, known as 'weight-normative', is replaced by health care professionals, public health officials and policy-makers with a 'weight-inclusive' approach.
It's not a movie about zombies, but it's a Halloween nightmare - at night while we sleep unaware, something deadly grows and spreads quickly. In a surprise finding, Weizmann Institute of Science researchers have found that nighttime is the right time for cancer to grow and spread in the body. Their findings suggest that administering certain treatments in time with the body’s day-night cycle could boost their efficiency.
A microRNA molecule has been tagged as a surprisingly crucial player in managing cell survival and growth. The findings underscore the emerging recognition that non-coding RNAs – small molecules that are not translated into working proteins – help regulate basic cellular processes and may be key to developing new drugs and therapies.
Principal investigator Albert R. La Spada, MD, PhD, professor of cellular and molecular medicine at UC San Diego, and colleagues found that a microRNA known as let-7 controls autophagy through the amino acid sensing pathway, which has emerged as the most potent activator of mTORC1 complex activity.
There are lots of distance runners in the United States, there is no real gender gap about participation. But there is when it comes to competition, the difference is there.
A new paper in Evolutionary Psychology says that, on average, American men participate at track meets about three times as often as American women, and this difference has been consistent since the late 1990s. By contrast, at road races, the sex difference in participation has disappeared.
In the past, researchers have primarily used the genetic history of mothers to understand evolution in animals, but a new study has investigated ancestry across the red fox genome, including the Y chromosome (paternal line) and found some surprises about the origins, journey and evolution of the red fox, the world's most widely distributed land carnivore.
Conventional thinking based on maternal genetics suggested that red foxes of Eurasia and North America composed a single interconnected population across the Bering land bridge between Asia and Alaska.
Isamu Akasaki, Hiroshi Amano and Shuji Nakamura have been award the 2014 Nobel Prize in Physics "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources". Using blue LEDs, white light can be created in a new way and that means LED lamps, which are longer-lasting and more efficient than incandescent sources.
Sodium is back in the health concern cycle and an analysis of data in the federal nationwide dietary intake survey known as "What We Eat in America NHANES 2009-2010," has led a team of Department of Agriculture (USDA) to conclude that, on any given day 49 percent of U.S. adults eat at least one sandwich, and sandwiches account for 20 percent of total daily sodium intake.
