94 For female mosquitoes, two sets of odor sensors are better than one
The malaria mosquito has a second complete set of odor receptors that are specially tuned to human scents, a team of biologists has found. www.sciencedaily.com/releas...
88 Eruptions on the sun trigger surprising phenomenon near Earth
Eruptions on the Sun's surface not only send bursts of energetic particles into the Earth's atmosphere causing disturbances in our planet's magnetic field, they can also strangely decrease the number of free electrons over large areas in the polar region of the ionosphere, new research concludes. www.sciencedaily.com/releas...
88 Next-gen steel under the microscope
Next-generation steel and metal alloys are a step closer to reality, thanks to an international research project. The work could overcome the problem of hydrogen alloy embrittlement that has led to catastrophic failures in major engineering and building projects. www.sciencedaily.com/releas...
86 Indigenous South American group has healthiest arteries of all populations yet studied, providing clues to healthy lifestyle
An 80 year old from the Tsimane (pronounced chee-MAH-nay) group had the same vascular age as an American in their mid-fifties, suggests a new report. The Tsimane people -- a forager-horticulturalist population of the Bolivian Amazon -- have the lowest reported levels of vascular aging for any population, with coronary atherosclerosis (hardening of the arteries) being five times less common than in the US, the research shows. www.sciencedaily.com/releas...
86 New study shakes the roots of the dinosaur family tree
More than a century of theory about the evolutionary history of dinosaurs has been turned on its head following the publication of new research. The work suggests that the family groupings need to be rearranged, redefined and renamed and also that dinosaurs may have originated in the northern hemisphere rather than the southern, as current thinking goes. www.sciencedaily.com/releas...
81 Solid metal has 'structural memory' of its liquid state
New research used high pressure and temperature to reveal a kind of 'structural memory' in samples of the metal bismuth, a discovery with great electrical engineering potential. www.sciencedaily.com/releas...
80 Mars volcano, Earth's dinosaurs went extinct about the same time
Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity, about 50 million years ago. The last volcanic activity there ceased about 50 million years ago -- around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct. www.sciencedaily.com/releas...
79 Research leads to a golden discovery for wearable technology
Researchers say they have developed a way to “grow” thin layers of gold on single crystal wafers of silicon, remove the gold foils, and use them as substrates on which to grow other electronic materials. www.sciencedaily.com/releas...
76 Intensive medical treatment can reverse type 2 diabetes
Type 2 diabetes can be reversed with intensive medical treatment using oral medications, insulin and lifestyle therapies, according to a study. www.sciencedaily.com/releas...
74 Overuse of antibiotics brings risks for bees, and for us
Honeybees treated with a common antibiotic were half as likely to survive the week after treatment compared with a group of untreated bees, a finding that may have health implications for bees and people alike. www.sciencedaily.com/releas...
