New planet-weighing technique found
New screening test to help people with hearing loss in China
Although there have been about 800 extra-solar planets discovered so far in our galaxy, the precise masses of the majority of them are still unknown, as the most-common planet-finding technique provides only a general idea of an object's mass. Previously, the only way to determine a planet's exact mass was if it transits. Former Carnegie scientist Mercedes López-Morales has, for the first time,...
New technique controls crystalline structure of titanium dioxide
The University of Southampton has developed a new hearing screening test which could help the estimated 100 million people suffering from hearing loss in China.
New treatment protocol extends survival in some cases of once inoperable pancreatic cancer
Researchers have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature. The development should make titanium dioxide more efficient in a range of applications, including photovoltaic cells, hydrogen production, antimicrobial coatings, smart sensors and optical communication technologies.
New vaccine for nicotine addiction
A Journal of the American College of Surgeons study reports on a comprehensive treatment strategy that increases long-term survival in some patients with a formerly inoperable pancreatic cancer.
New way of probing exoplanet atmospheres
Researchers at Weill Cornell Medical College have developed and successfully tested in mice an innovative vaccine to treat nicotine addiction.
Obese appendectomy patients have fewer complications with minimally invasive operations
For the first time a new technique has allowed astronomers to study the atmosphere of an exoplanet in detail -- even though it does not pass in front of its parent star. An international team has used ESO's Very Large Telescope to directly catch the faint glow from the planet Tau Boötis b, solving a 15-year-old problem. The team also finds that the planet's atmosphere seems to be cooler higher...
ORNL/UTK team maps the nuclear landscape
Obese patients who have their appendixes removed via a minimally invasive surgical procedure fare better.
Palladium-gold nanoparticles clean TCE a billion times faster than iron filings
An Oak Ridge National Laboratory and University of Tennessee team has used the Department of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics.
Parkinson's disease gene identified with help of Mennonite family: UBC-VCH research
In the first side-by-side tests of a half-dozen palladium- and iron-based catalysts for cleaning up the carcinogen TCE, Rice University scientists have found that palladium destroys TCE far faster than iron -- up to a billion times faster in some cases.
Patient care by residents is as good as by fully qualified doctors
An international team led by human genetic researchers at the University of British Columbia and Vancouver Coastal Health has identified the latest gene associated with typical late-onset Lewy body Parkinson's disease, with the help of a Canadian Mennonite family of Dutch-German-Russian ancestry.
Picking the pig with the perfect pins
Medical residents are an essential part of the hospital workforce. Although still in training the take on much of the day to day care of patients. A systematic review published in BioMed Central's open-access journal BMC Medicine shows that patient by properly supervised residents care is safe and of equal quality to that of fully trained doctors.
Pressure testing of new Alvin Personnel Sphere successful
Video motion capture is being used by experts at Newcastle University to identify the early signs of lameness in pigs.
Probing the roots of depression by tracking serotonin regulation at a new level
The human-occupied submersible Alvin reached a major milestone in its upgrade project on June 22 when its new titanium personnel sphere successfully completed pressure testing, reports the Woods Hole Oceanographic Institution, the vehicle's operator.
Racial make-up of community impacts obesity risk
An interdisciplinary team of scientists have successfully tagged a protein that regulates the neurotransmitter serotonin with tiny fluorescent beads, allowing them to track the movements of individual molecules for the first time. This capability makes it possible to study the manner in which serotonin regulates mood, appetite and sleep at a new level of detail.
Regulation of telomerase in stem cells and cancer cells
The racial and ethnic composition of a community is associated with the obesity risk of individuals living within the community, according to a study led by researchers at the Agency for Healthcare Research and Quality and the Johns Hopkins Bloomberg School of Public Health. The findings may help explain disparities in obesity rates among racial groups and point to some of the environmental...
Scientists identify new cancer stem cell mechanism
Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have gained important insights for stem cell research which are also applicable to human tumors and could lead to the development of new treatments.
Scientists measure soot particles in flight
A link between two genes which shows how stem cells could develop into cancer has been uncovered by scientists at Queen Mary, University of London.
Scripps Research Institute scientists find easier way to make new drug compounds
For the first time, air-polluting soot particles have been imaged in flight down to nanometer resolution. Pioneering a new technique, the international team, including researchers from DESY, snapped the most detailed images yet of airborne aerosols.
Sensitive test helps improve vaccine safety
Scientists at the Scripps Research Institute have developed a powerful new technique for manipulating the building-block molecules of organic chemistry. The technique enables chemists to add new functional molecules to previously hard-to-reach positions on existing compounds -- making it easier for them to generate new drugs and other organic chemicals.
Smartphones have increased use of social media and computer games
Salmonella Typhi (S. Typhi) is the causative agent of typhoid fever, a serious health threat resulting in some 22 million new cases yearly and approximately 217,000 fatalities. Karen Brenneman and her colleagues at Arizona State University's Biodesign Institute have been examining ways to detect the presence of S. Typhi in stool following inoculation with various vaccine strains.
Smoking, head injury, pesticide use may be risk factors for rare sleep disorder
Over 60 percent of Swedish young people today have a smartphone, and in addition to telephoning and messaging, they use them to communicate via social media and e-mail, and to play games.
Social issues in teen years can hurt future health
Smoking, head injury, pesticide exposure, farming and less education may be risk factors for a rare sleep disorder that causes people to kick or punch during sleep, according to a study published in the June 27, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology.
Space tornadoes power the atmosphere of the Sun
A study shows a correlation between peer problems in adolescence and metabolic syndrome in adulthood.
Specialized MRI scans assess value of anti-cancer chemotherapy long before tumors shown to shrink
Mathematicians at the University of Sheffield, as part of an international team, have discovered tornadoes in space which could hold the key to power the atmosphere of the Sun to millions of kelvin.
Studies on some 55 US men and women with potentially deadly liver or pancreatic cancers show that specialized MRI scans can tell within a month whether highly toxic chemotherapy is working and killing tumor cells long before tumors actually shrink -- or fail to shrink.
