90 Obesity is top cause of preventable life-years lost, study shows
Obesity resulted in as much as 47 percent more life-years lost than tobacco, and tobacco caused similar life-years lost as high blood pressure, new research has shown. www.sciencedaily.com/releas...
90 Nanoparticle vaccine shows potential as immunotherapy to fight multiple cancer types
A first-of-its-kind nanoparticle vaccine immunotherapy has been developed that targets several different cancer types, outlines a new report. www.sciencedaily.com/releas...
74 Genetics, environment combine to give everyone a unique sense of smell
Receptors in the noses of mice exposed to certain smells during life are different to genetically similar mice that lived without those smells, new research shows. The study found it is this combination of genetics and experience that gives each individual a unique sense of smell. www.sciencedaily.com/releas...
98 Protein in human umbilical cord blood rejuvenates old mice's impaired learning, memory
Human umbilical cord blood can rejuvenate learning and memory in older mice, according to a new study. The findings could lead to new treatments for age-associated declines in mental ability. www.sciencedaily.com/releas...
93 Hunting accounts for 83 and 58 percent declines in tropical mammal and bird populations
Hunting is a major threat to wildlife particularly in tropical regions, but a systematic large-scale estimate of hunting-induced declines of animal numbers was lacking so far. A study now fills this gap. An international team of ecologists and environmental scientists found that bird and mammal populations were reduced within 7 and 40 km of hunters' access points, such as roads and settlements. www.sciencedaily.com/releas...
89 Light rays from a supernova bent by the curvature of space-time around a galaxy
Astronomers have detected for the first time multiple images from a gravitationally lensed Type Ia supernova. The new observations suggest promising new avenues for the study of the accelerated expansion of the universe, gravity and distribution of dark matter in the universe. www.sciencedaily.com/releas...
86 Harnessing heat to power computers
Heat is commonly regarded as computing's mortal enemy. Two researchers, however, flipped the question of how to keep computers cool to how to use heat as an alternative energy source. www.sciencedaily.com/releas...
84 How nature engineered the original rotary motor
To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting measurements. In a new study, researchers report the eludication of a mechanism that regulates the length of the flagellum's 25 nanometer driveshaft-like rod and answers a long-standing question about how cells are held together. www.sciencedaily.com/releas...
84 Surprising brain change appears to drive alcohol dependence
We may be one step closer to personalized treatments for alcoholism and alcohol use disorder following results of a recent study, say researchers. www.sciencedaily.com/releas...
93 Man moves paralyzed legs using device that stimulates spinal cord
Electrical stimulation was used on the spinal cord of a patient in a new study, and combined with intense physical therapy, the man intentionally moved his paralyzed legs, stood and made steplike motions for the first time in three years. www.sciencedaily.com/releas...
