New theory of gravity might explain dark matter
Phys.org - 8 Nov 2016 13:06
A new theory of gravity might explain the curious motions of stars in galaxies. Emergent gravity, as the new theory is called, predicts the exact same deviation of motions that is usually explained by invoking dark matte...
PPPL physicists build diagnostic that measures plasma velocity in real time
Phys.org - 8 Nov 2016 23:28
Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a diagnostic that provides crucial real-time information about the ultrahot plasma swirling within doughnut-sh...
Early exposure to excess hormone causes genital defects in females
Science Daily - 8 Nov 2016 22:26
Researchers have identified cells targeted by a male hormone and found that an excess of that hormone at a specific time can cause genital defects in female mice.
Evolution purged many Neanderthal genes from human genome
Science Daily - 8 Nov 2016 21:52
Larger populations allowed humans to shed weakly deleterious gene variants that were widespread in Neanderthals, new research indicates.
Humans have purged the bad genes from our Neanderthal hook-ups
New Scientist - 8 Nov 2016 21:01
Early modern humans interbred with Neanderthals, but thanks to our bigger population evolution has purged out many of the deleterious genes we acquired this way
Tailored, dense-dose chemotherapy for early breast cancer does not result in significant improvement
Science Daily - 8 Nov 2016 20:16
Among women with high-risk early breast cancer, the use of tailored dose-dense chemotherapy compared with standard adjuvant chemotherapy did not result in a statistically significant improvement in breast cancer recurren...
Supplemental, nutrient-enriched donor milk does not improve neurodevelopment in very low-birth-weight infants
Science Daily - 8 Nov 2016 20:16
Among very low-birth-weight (VLBW) infants, the use of supplemental donor milk compared with formula did not improve neurodevelopment at 18 months, according to a study.
More frequent vaping among teens linked to higher risk of heavy cigarette smoking
Science Daily - 8 Nov 2016 20:15
Scientists examined associations of e-cigarette vaping with subsequent smoking frequency and heavy smoking among adolescents. E-cigarette vaping is reported by 37 percent of U.S. 10th-grade adolescents and is associated ...
Genetically engineering disease-fighting cells
Science Daily - 8 Nov 2016 20:12
The human body produces T cells to recognize and fight disease. Each T cell has a unique T cell receptor (or TCR) on its surface that surveils small fragments of proteins presented by other cells. Upon detecting evidence...
ExoMars crash must not mean abandoning next Red Planet rover
New Scientist - 8 Nov 2016 20:09
A critical point looms for Europe's life-hunting Mars rover after its test lander crashed. It must roll on, say astrobiologists Dirk Schulze-Makuch and Alberto Fairén
