|Scientists dig into the origin of organics on dwarf planet Ceres|
|Wed, 18 Oct 2017 15:18:29 EDT|
Since NASA's Dawn spacecraft detected localized organic-rich material on Ceres, scientists have been digging into the data to explore different scenarios for its origin. After considering the viability of comet or asteroid delivery, the preponderance of evidence suggests the organics are most likely native to Ceres.
|Obesity: Engineered proteins lower body weight in mice, rats and primates|
|Wed, 18 Oct 2017 15:18:20 EDT|
Researchers have created engineered proteins that lowered body weight, bloodstream insulin, and cholesterol levels in obese mice, rats, and primates.
|Duplications of noncoding DNA may have affected evolution of human-specific traits|
|Wed, 18 Oct 2017 13:32:30 EDT|
Duplications of large segments of noncoding DNA in the human genome may have contributed to the emergence of differences between humans and nonhuman primates, according to new results. Identifying these duplications, which include regulatory sequences, and their effect on traits and behavior may help scientists explain genetic contributions to human disease.
|Online resource enables open data sharing for rare Mendelian diseases|
|Wed, 18 Oct 2017 13:32:26 EDT|
MyGene2, a new open data resource, helps patients with rare genetic conditions, clinicians, and researchers share information, connect with one another, and enable faster gene discovery.
|Understanding the coevolving web of life as a network|
|Wed, 18 Oct 2017 13:32:22 EDT|
Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic partners. But many species have mutualistic interactions with multiple partners, leading to complex networks of interacting species.
|New material for digital memories of the future|
|Wed, 18 Oct 2017 13:32:19 EDT|
Scientists have developed the first material with conductivity properties that can be switched on and off using ferroelectric polarization.
|At tremendous precision, the proton and antiproton still seem identical|
|Wed, 18 Oct 2017 13:29:12 EDT|
Using a novel two-particle measurement method, a group of researchers measured the magnetic moment of the antiproton at a precision 350 times higher than any previous measurement. The result shows that the magnetic moments of the proton and antiproton are tremendously close, meaning that so-called CPT asymmetry -- a key factor in the lack of antimatter -- must be very small if it exists at all.
|Nature or nurture£ Innate social behaviors in the mouse brain|
|Wed, 18 Oct 2017 13:29:06 EDT|
The brain circuitry that controls innate, or instinctive, behaviors such as mating and fighting was thought to be genetically hardwired. Not so, neuroscientists now say.
|Riddle of matter remains unsolved: Proton and antiproton share fundamental properties|
|Wed, 18 Oct 2017 13:28:37 EDT|
Physicists have been able to measure the magnetic force of antiprotons with almost unbelievable precision.
|Inflammation trains the skin to heal faster|
|Wed, 18 Oct 2017 13:28:31 EDT|
Stem cells in the skin remember an injury, helping them close recurring wounds faster, researchers have found. The discovery could advance research and treatment of psoriasis and other inflammatory diseases.
|Petals produce a 'blue halo' that helps bees find flowers|
|Wed, 18 Oct 2017 13:28:26 EDT|
Latest research has found that several common flower species have nanoscale ridges on the surface of their petals that meddle with light when viewed from certain angles.
|Solar eruptions could electrify Martian moons|
|Wed, 18 Oct 2017 12:41:40 EDT|
Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study. The study also considered electrical charges that could develop as astronauts transit the surface on potential human missions to Phobos.
|For $1000, anyone can purchase online ads to track your location and app use|
|Wed, 18 Oct 2017 12:41:31 EDT|
New research finds that for a budget of roughly $1000, it is possible for someone to track your location and app use by purchasing and targeting mobile ads. The team hopes to raise industry awareness about the potential privacy threat.
|Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report|
|Wed, 18 Oct 2017 12:17:06 EDT|
Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.
|New findings explain how UV rays trigger skin cancer|
|Wed, 18 Oct 2017 12:16:57 EDT|
Melanoma, a cancer of skin pigment cells called melanocytes, will strike an estimated 87,110 people in the US in 2017, according to the Centers for Disease Control and Prevention. A fraction of those melanomas come from pre-existing moles, but the majority of them come from sources unknown -- until now.
