Though people often think of the benefits from exercise, calorie restriction and weight loss as interchangeable, it appears that they may all offer distinct and cumulative benefits when it comes to managing Type 2 diabetes risk.
Some 9 million American families lost their homes to foreclosure during the late 2000s housing bust, driving many to economic ruin and in search of new residences. Hardest hit were black, Latino, and racially integrated neighborhoods, according to a new Cornell University analysis of the crisis.
Not everyone may care about having an impressive job title or a big, fancy house but all human beings desire a high level of social status, according to a newly published study.
Researchers from Berkeley Lab and the University of Hawaii at Manoa have shown for the first time that cosmic hot spots, such as those near stars, could be excellent environments for the creation of molecular precursors to DNA.
In a synergy between the Hubble and Spitzer space telescopes, and the giant W. M. Keck Observatory, astronomers have set a new distance record to the farthest redshift-confirmed galaxy. It is so far away the light we receive left the galaxy over 13 billion years ago, and it is just arriving now. The new observations underline the very exciting discoveries that NASA's James Webb Space Telescope will enable when it is launched in 2018.
The onion, a humble root vegetable, is proving its strength outside the culinary world -- in an artificial muscle created from onion cells. Unlike previous artificial muscles, this one, created by researchers from National Taiwan University, can either expand or contract to bend in different directions depending on the driving voltage applied. The finding is published this week in the journal Applied Physics Letters.
Conventional semiconductor detectors made from germanium and silicon are standard equipment in nuclear physics, but are less useful in many emerging applications because they require low temperatures to operate. In recent years, scientists have been seeking new semiconductor materials to develop high-performance radiation detectors that can operate at room temperature, and now researchers from Oak Ridge National Laboratory think they have a good candidate material: a compound called thallium sulfide iodide.
Although the human ability to write evolved from our ability to speak, writing and talking are now such independent systems in the brain that someone who can’t write a grammatically correct sentence may be able say it aloud flawlessly.
They may not be on Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, according to a recent study by scientists at Harbor Branch Oceanographic Institute at Florida Atlantic University. Dolphins are known for being highly social animals, and a team of researchers at HBOI took a closer look at the interactions between bottlenose dolphins in the Indian River Lagoon (IRL) and discovered how they mingle and with whom they spend their time.
People with depression or bipolar disorder often feel their thinking ability has gotten “fuzzy”, or less sharp than before their symptoms began. Now, researchers have shown in a large study that effect is indeed real – and rooted in brain activity differences that show up on advanced brain scans.
Researchers have uncovered a unique connection between diabetes and Alzheimer’s disease, providing further evidence that a disease that robs people of their memories may be affected by elevated blood sugar.
Bioluminescence at least in one millipede may have evolved as a way to survive in a hot, dry environment, not as a means to ward off predators, according to scientists publishing in this week’s Proceedings of the National Academy of Sciences.
Kansas State University kinesiology research offers encouraging information for cancer patients: A brisk walk or a slow jog on a regular basis may be the key to improved cancer treatments.
Doping is damaging the image of sport without benefitting athletes’ results, according to University of Adelaide research.
A cross-institutional team of researchers have identified a signaling substance (MuIS) that may predict patients who will have poor muscle regeneration outcomes following hip surgery. Testing patients for the presence of MuIS before surgery may help clinicians better plan for those who will need more intensive rehab post-surgery.
Gene therapy for Leber congenital amaurosis (LCA), an inherited disorder that causes loss of night- and day-vision starting in childhood, improved patients’ eyesight within weeks of treatment in a clinical trial of 15 children and adults at the Scheie Eye Institute at the Perelman School of Medicine at the University of Pennsylvania. New results involving a subset of patients from the ongoing trial show that these benefits peaked one to three years after treatment and then diminished. The findings are published today in The New England Journal of Medicine.
What happens to an astronaut’s brain during a mission to Mars? Nothing good. It’s besieged by destructive particles that can forever impair cognition, according to a UC Irvine radiation oncology study appearing in the May 1 edition of Science Advances. Charles Limoli and colleagues found that exposure to highly energetic charged particles – much like those found in the galactic cosmic rays that bombard astronauts during extended spaceflights – cause significant damage to the central nervous system, resulting in cognitive impairments.
Researchers using the Advanced Photon Source, a Department of Energy user facility at Argonne National Laboratory, have gotten the first-ever look inside the living beetle as it sprays. The results are published today in Science.
A team of highly determined high school students discovered a never-before-seen pulsar by painstakingly analyzing data from the National Science Foundation’s (NSF) Robert C. Byrd Green Bank Telescope (GBT). Further observations by astronomers using the GBT revealed that this pulsar has the widest orbit of any around a neutron star and is part of only a handful of double neutron star systems.
A team of researchers from the University of California, Davis, the Wildlife Conservation Society, and other groups has focused its attention on fishery improvement projects (FIPs), which are designed to bring seafood from wild fisheries to the certified market, with only a promise of sustainability in the future. They conclude that FIPs need to be fine-tuned to ensure that fisheries are delivering on their promises.
Tax cuts for ordinary Americans boost economic growth and create jobs, while tax breaks for the rich do little to help the economy.

Researchers find that having sleep apnea while pregnant could make the baby prone to metabolic disease as an adult.
Luke Skywalker’s home in “Star Wars” is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, and many researchers believe rocky planets cannot form there. Now, mathematical simulations show that Earthlike, solid planets such as Tatooine likely exist and may be widespread.
A new study led by Scripps Institution of Oceanography at UC San Diego researchers has revealed that the thickness of Antarctica’s floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is responding to climate change.
Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at Washington University School of Medicine in St. Louis.
