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.
