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.
The downside to solar and wind is not just low efficiency and high cost, it is also that they are intermittent. But that impacts cost also. Relying on them has meant contracting with traditional energy companies to be 'on demand' at far higher cost than they otherwise would be, to be on call to shut off or add electricity as needed.
Wind will never be a serious alternative but solar is the future. Yet no matter how good solar becomes, there will still be a problem of storage and riding out its fluctuations - and existing storage capacities are far from adequate for the purpose.
Global warming is currently taking a break. Global temperatures seemed to have risen drastically into the late 1990s but the global average temperature has risen only slightly since 1998 – surprising, considering scientific climate models predicted considerable warming due to rising greenhouse gas emissions. In 2006, former U.S. Vice-President Al Gore said by 2016 it would be too late if we did not stop CO2 immediately.
Climate skeptics use this contradiction to question climate change as well as the validity of climate models. Meanwhile, the majority of climate researchers continued to emphasize that a short-term 'warming hiatus' can largely be explained on the basis of current scientific understanding and did not contradict longer term warming.
A new implantable tissue scaffold coated has been created, with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue.
Love and commitment make sex physically more satisfying for many women, according to Penn State Abington sociologist Beth Montemurro.
In interviews of 95 heterosexual women between the ages of 20 and 68 and from a range of backgrounds, most believed love was necessary for maximum satisfaction in both sexual relationships and marriage. The benefits of being in love with a sexual partner were more than just emotional, most of the women in the study said that love made sex physically more pleasurable. From September 2008 to July 2011, Montemurro conducted in-depth interviews with 95 women who lived in Pennsylvania, New Jersey and New York, lasting about 90 minutes each.
The United States Supreme Court recently ruled against the Obama administration requirement that all employers must provide birth control insurance for women. Administration lawyers knew they were on shaky ground going in, because there were no provisions for male sex lives, such as Viagra, and that meant the policy was discriminatory, and the Supreme Court might rule that all corporations have the same rights, regardless of size, which further weakens the long-term viability of the ACA.
Schizophrenia is among the most severe forms of mental illness yet some people are as happy as those in good mental health and happier than many, according to a paper in Schizophrenia Research.
In a survey of people with the disease, researchers found that 37 percent of patients reported being happy all or most of the time.
In China, there is no wage disparity for one classification of women but there is pay inequality among similarly classed men, according to a sociology presentation at the Annual Meeting of the American Sociological Association which analyzed economic disparity among obese Chinese adults.
What is the classification? Obese people. When men gain weight, they are penalized in wages compared to thinner men. With women, there is no difference.
The Hypatia Catalog is the largest catalog ever produced for stellar compositions and seeks to help in understanding the properties of stars, how they form, and possible connections with orbiting planets.
Named after one of the first female astronomers, who lived ~350 A.D. in Alexandria, the digital catalog is a compilation of spectroscopic abundance data from 84 literature sources for 50 elements across 3,058 stars in the solar neighborhood, within 500 light years of the Sun. It essentially lists the compositions of stars, but only stars that are like the Sun – or F-, G-, or K-type (the Sun is a G-type star) – that are relatively near to the Sun.
Researchers trying to get new information about the metabolism of plants can switch off individual genes and study the resulting changes but researchers in a new study adopted a different approach.
Erich Kombrink from the Max Planck Institute for Plant Breeding Research in Cologne and Markus Kaiser from the University of Duisburg-Essen have identified small molecules that block specific components of the metabolic process like brake pads and prevent the downstream reactions. In their search for these molecules, they used a biological selection process involving intact plants, a technique borrowed from corporate drug research.
Can math be evidence? Not ordinarily, but recent calculations are compelling because they show that particles predicted by the theory of quark-gluon interactions but never observed are being produced in heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC), located at Brookhaven National Laboratory.
They just need to be detected. These heavy strange baryons, containing at least one strange quark, still cannot be observed directly, but instead are making their presence known by lowering the temperature at which other strange baryons "freeze out" from the quark-gluon plasma (QGP) discovered and created at the RHIC.
American CO2 emissions have plummeted thanks to natural gas and energy emissions from coal have not been this low since the early 1980s, but a decades long war against energy science meant nuclear power - a truly viable emissions-free source - was scuttled and that meant more coal plants starting in the early 1990s, which meant more CO2.
The bacterium Clostridium difficile causes antibiotic-related diarrhea and is a growing problem in the hospital environment and elsewhere in the community. Understanding how the microbe colonizes the human gut when other "healthy" microbes have been destroyed during a course of antibiotics might lead to new ways to control infection.
