New research reveals that the more people think they know about a topic in general, the more likely they are to allege knowledge of completely made-up information and false facts, a phenomenon known as "overclaiming." The findings are published in Psychological Science, a journal of the Association for Psychological Science. "Our work suggests that the seemingly straightforward task of judging one's knowledge may not be so simple, particularly for individuals who believe they have a relatively high level of knowledge to begin with," says psychological scientist Stav Atir ...

HER2 membrane proteins play a special role in certain types of breast cancer: amplified levels of HER2 drive unrestricted cell growth. HER2-tailored antibody-based therapeutics aim to prevent cancer cell growth. However, two-thirds of HER2 positive breast cancer patients develop resistance against HER2-targeting drugs. The reason for this is not yet understood. Researchers now found out, that HER2 dimers appeared to be absent from a small sub-population of resting SKBR3 breast cancer cells. This small subpopulation may have self-renewing properties that are resistant to ...

SAN ANTONIO (July 17, 2015) -- Researchers from the School of Medicine at The University of Texas Health Science Center at San Antonio have found evidence that directly links disrupted metabolism (energy production in cells) to a common and often fatal type of lymphoma. The finding was announced Thursday (July 16) in Nature Communications. "The link between metabolism and cancer has been proposed or inferred to exist for a long time, but what is more scarce is evidence for a direct connection -- genetic mutations in metabolic enzymes," said senior author Ricardo C.T. ...

Lower levels of cholesterol in certain immune cells--a result of enhanced cholesterol metabolism within those cells--may help explain why some HIV-infected people are able to naturally control disease progression, according to research that will be presented in a poster at the 8th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2015) in Vancouver, Canada, and the pre-conference 2015 Towards an HIV Cure Symposium. The findings provide a basis for potential development of new approaches to control HIV infection by regulating cellular ...

Washington, DC - July 17, 2015 - The success of probiotics for boosting human health may depend partly upon the food, beverage, or other material carrying the probiotics, according to research published on July 10th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. "Our findings indicate that the manner in which a probiotic is delivered--whether in food or supplement form--could influence how effective that probiotic is in delivering the desired health benefits," said corresponding author Maria Marco, PhD, an associate professor ...

When a power company wants to build a new wind farm, it generally hires a consultant to make wind speed measurements at the proposed site for eight to 12 months. Those measurements are correlated with historical data and used to assess the site's power-generation capacity. At the International Joint Conference on Artificial Intelligence later this month, MIT researchers will present a new statistical technique that yields better wind-speed predictions than existing techniques do -- even when it uses only three months' worth of data. That could save power companies time ...

This breakthrough has the potential to facilitate new discoveries in gene therapies and basic genetics research. The research was published in the July 13 issue of Nature Methods. The study describes an approach to simplify a laborious part of the gene editing process using the CRISPR/Cas9 system: choosing the best ...

ROSEMONT, IL - Teaching coaches about injury prevention and contact restrictions pays off, say researchers who tracked injury rates among youth football players during the 2014 season. "With an estimated three million youth aged 7 to 14 years old playing tackle football each year, preventing injuries is key. Our study showed that kids who received a comprehensive education from a coach had fewer injuries," said lead author Zachary Y. Kerr, PhD, MPH of the Datalys Center for Injury Research and Prevention. Kerr and his team had athletic trainers evaluate and track ...

Genetic differences between hemp and marijuana determine whether Cannabis plants have the potential for psychoactivity, a new study by University of Minnesota scientists shows. "Given the diversity of cultivated forms of Cannabis, we wanted to identify the genes responsible for differences in drug content," says U of M plant biologist George Weiblen. While marijuana is rich in psychoactive tetrahydrocannabinol (THC), hemp produces mostly a non-euphoric cannabidiol (CBD), but the genetic basis for this difference was a matter of speculation until now. The study was published ...

A solar cell that produces fuel rather than electricity. Researchers at Eindhoven University of Technology (TU/e) and FOM Foundation today present a very promising prototype of this in the journal Nature Communications. The material gallium phosphide enables their solar cell to produce the clean fuel hydrogen gas from liquid water. Processing the gallium phosphide in the form of very small nanowires is novel and helps to boost the yield by a factor of ten. And does so using ten thousand times less precious material. The electricity produced by a solar cell can be used ...

Despite scientific evidence to the contrary, a small group of otolaryngologists have repeatedly testified, on behalf of the tobacco industry, that heavy smoking did not cause the cancer in cases of dying patients suing for damages, according to a study by a Stanford University School of Medicine researcher. "I was shocked by the degree to which these physicians were willing to testify, in my opinion in an unscientific way, to deny a dying plaintiff -- suffering the aftermath of a lifetime of smoking -- of a fair trial," said Robert Jackler, MD, professor and chair of ...

PHILADELPHIA (July 17, 2015) - A new study from the Monell Center and collaborating institutions suggests that a single set of genes affects a person's perception of sweet taste, regardless of whether the sweetener is a natural sugar or a non-caloric sugar substitute. "Eating too much sugar is often seen as a personal weakness. However, our work suggests that part of what determines our perception of sweetness is inborn in our genetic makeup," said study author Danielle Reed, PhD, a behavioral geneticist at Monell. "Just as people born with a poor sense of hearing may ...

New research from the University of East Anglia (UEA) shows how investors can significantly reduce the cost of implementing portfolio strategies - in some cases by more than 90 per cent. The study, published today in the journal Financial Review, shows that many modern investment strategies often lead to low returns or even lose money in practice, as they are prone to large trading costs. Such costs include bid-ask spreads, brokerage fees and capital gain taxes and can dramatically affect investment returns, turning an otherwise winning strategy into a losing one. Many ...

The location of the second largest volcanic eruption in human history, the waters off Greece's Santorini are the site of newly discovered opalescent pools forming at 250 meters depth. The interconnected series of meandering, iridescent white pools contain high concentrations of carbon dioxide (CO2) and may hold answers to questions related to deepsea carbon storage as well as provide a means of monitoring the volcano for future eruptions. "The volcanic eruption at Santorini in 1600 B.C. wiped out the Minoan civilization living along the Aegean Sea," said Woods Hole Oceanographic ...

New Haven, Conn. -- Researchers at the Aortic Institute at Yale have tested the genomes of more than 100 patients with thoracic aortic aneurysms, a potentially lethal condition, and provided genetically personalized care. Their work will also lead to the development of a "dictionary" of genes specific to the disease, according to researchers. The study published early online in The Annals of Thoracic Surgery. Experts have known for more than a decade that thoracic aortic aneurysms -- abnormal enlargements of the aorta in the chest area --run in families and are caused ...

A newly discovered family of chemical structures, published in Nature today, could increase the value of biogas and natural gas that contains carbon dioxide. The new chemical structures, known as zeolites, have been created by an international team of researchers including Professor Xiaodong Zou and co-workers from the Department of Materials and Environmental Chemistry at Stockholm University. The zeolites -- crystalline aluminosilicates with frameworks that contain windows and cavities the size of small molecules -- can separate out carbon dioxide more effectively ...

CAMBRIDGE, Mass--Part of a 1929 prediction by physicist Hermann Weyl -- of a kind of massless particle that features a singular point in its energy spectrum called the "Weyl point," -- has finally been confirmed by direct observation for the first time, says an international team of physicists led by researchers at MIT. The finding could lead to new kinds of high-power single-mode lasers and other optical devices, the team says. For decades, physicists thought that the subatomic particles called neutrinos were, in fact, the massless particles that Weyl had predicted -- ...

EDMONTON (July 16, 2015)--Humans depend on high levels of ecosystem biodiversity, but due to climate change and changes in land use, biodiversity loss is now greater than at any time in human history. Five University of Alberta researchers, including students, participated in a leading global initiative to determine whether there are widespread and consistent patterns in plant biodiversity. Sixty-two scientists from 19 countries spanning six continents studied the relationships between plant biomass production and species diversity, culminating in a paper appearing in ...

PITTSBURGH--When it comes to developing efficient, robust networks, the brain may often know best. Researchers from Carnegie Mellon University and the Salk Institute for Biological Studies have, for the first time, determined the rate at which the developing brain eliminates unneeded connections between neurons during early childhood. Though engineers use a dramatically different approach to build distributed networks of computers and sensors, the research team of computer scientists discovered that their newfound insights could be used to improve the robustness and ...

The Ebola epidemic and resulting international public health emergency is referred to as a "Black Swan" event in medical circles because of its unpredictable and impactful nature. However, a paper in the June 30 issue of Clinical Infectious Diseases, a leading journal in the field of infectious diseases, suggests that the response of the Chicago Ebola Response Network (CERN) in 2014-2015 has laid a foundation and a roadmap for how a regional public health network can anticipate, manage and prevent the next Black Swan public health event. By sharing the expertise, risk ...

New Johns Hopkins Bloomberg School of Public Health research finds new evidence that an extremely high number of people in southern India are exposed to two mosquito-borne viruses -- dengue and chikungunya. These findings, the researchers say, reinforce the need for officials to be on the lookout for these diseases and to find ways to control its spread not only in India but also around the world. The researchers, reporting July 16 in PLOS Neglected Tropical Diseases, tested blood samples from 1,010 people across 50 locations in Chennai, a city with over 6 million people ...
