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 recently published paper strongly suggests men succumb to sexual temptations more than women — for example, cheating on a partner or stealing a girl from another guy — because they experience strong sexual impulses, not because they have weak self-control. At least when it comes to those of college age.
Previous papers have said that men are more likely than women to pursue romantic partners that are "off limits" but there has been no real theoretical explanation for this sex difference.
Chaotic terrains are enigmatic features stretching up to hundreds of kilometres across Mars. The mechanism by which they formed is hypothesis and even speculation in most cases.A recent paper, which combines observations from satellite photos of the 280 kilometere wide and four kilometer deep crater plus models of the ice melting process and resulting catastrophic outflow, says that Aram Chaos, the lumpy, bumpy floor of an ancient impact crater on Mars, formed as a result of catastrophic melting and outflow of a buried ice lake.
The solar system is crowded with small objects like asteroids and comets, and most have stable orbits which keep them out of harm’s way, but a small proportion of them are in orbits that risk collision with planets.Smaller objects are more numerous and therefore result in more frequent collisions. The recent meteor seen over Chelyabinsk, Russia, in February 2013, was rare because the object was relatively large, around 17 meters across. However, the giant planet Jupiter is a much bigger target due to its tremendous gravitational attraction -- and it gets hit far more often than the Earth. The collisions are also much faster, happening at a minimum speed of 60 kilometers per second.
Working with cells in vitro and in mice, researchers have discovered that an antioxidant called ethoxyquin, a chemical commonly used as a dog food preservative, may prevent the kind of painful nerve damage found in the hands and feet of four out of five cancer patients taking the chemotherapy drug Taxol.
Ethoxyquin is a Food and Drug Administration-approved preservative and was shown in the new experiments to bind to certain cell proteins in a way that limits their exposure to the damaging effects of Taxol, the researchers say.
There are lots of ideas on how healthy habits transform into long-term lifestyle changes.
PhD candidate Marc Mitchell,writing in the American Journal of Preventive Medicine, suggests that receiving coupons and vouchers for as little as five dollars can help people stick to new fitness regimes. Under the guidance of Professors Jack Goodman and Guy Faulkner, Mitchell has completed a systematic review of research into the efficacy of financial incentives in inspiring lifestyle and health behavior change, specifically in people who've experienced cardiac problems. His analysis suggests that these small rewards increase the odds that patients will maintain an active lifestyle in the longer term.
Mayo Clinic researchers have shown that a specific protein pair may be a successful prognostic biomarker for identifying smoking-related lung cancers. The protein — ASCL1 — is associated with increased expression of the RET oncogene, a particular cancer-causing gene called RET. The findings appear in the online issue of the journal Oncogene.
"This is exciting because we've found what we believe to be a 'drugable target' here," says George Vasmatzis, Ph.D., a Mayo Clinic molecular medicine researcher and senior author on the study. "It's a clear biomarker for aggressive adenocarcinomas. These are the fast-growing cancer cells found in smokers' lungs."
A bone fragment from a French archaeological site has turned out to be a part of an early specialized bone tool used by a Neanderthal before the first modern humans appeared in Europe.
Super Typhoon Usagi and its 150 MPH winds will be the strongest weather event this year.
The radar on the Tropical Rainfall Measuring Mission (TRMM) satellite captured an image of Supertyphoon Usagi near the end of a 24-hour period in which Usagi intensified by 65 knots. This is more than twice the commonly used 30-knot threshold for defining rapid intensification. The TRMM data was used to create a 3-D image. The data was collected at 1035 UTC/6:35 a.m. EDT on Thursday, September 19, 2013, when Usagi was at category 3 on the Saffir-Simpson hurricane intensity scale.
Like many other transgenic crops, Bt maize synthesises its own pesticide - a toxic protein produced in its leaves and stems, which kills pests in a matter of days. It's perfect, except, as will eventually happen in all pest control instances, when insect populations develop resistance to the toxin. That is why there are controls on how much Bt maize is in an area. To date, management strategies implemented to delay the evolution of resistance have been successful.
While you are reading this article, you could be getting a little smarter, but you could also be losing important information.An idle brain is still doing important work and in the age of constant information overload, it’s a good idea to go offline on a regular basis, says Erik Fransén, a researcher from Stockholm's KTH Royal Institute of Technology.
Telomerase is an enzyme that is the hallmark of both aging and the uncontrolled cell division associated with cancer and in an effort to understand and control telomerase activity, researchers at The Wistar Institute have discovered a protein "motif," named TFLY, which is crucial to the function of telomerase.
Altering this motif disrupts telomerase function, they found, a fact that they believe will help them in their efforts to identify inhibitors of telomerase with potential cancer therapeutic properties.
Calcium helps strengthen bones in people but it is also a critical nutrient for healthy tree growth and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the effects of acid rain.
