Fourth- and eighth-graders score better than before, but weak gains and overall poor marks hint at long way to go --
The 9 Deadliest Viruses on Earth
Live Science - 27 Oct 2016 09:20
Humans have been fighting viruses throughout history. Here are the nine viruses that are the world's worst killers, based on their mortality rates, or the sheer numbers of people they have killed.
Gamma ray camera offers new view on ultra-high energy electrons in plasma
Phys.org - 27 Oct 2016 22:50
Researchers at General Atomics (GA) have invented a new kind of gamma ray camera that can image beams of energetic electrons inside ultra-hot fusion plasma.
General atomics breakthrough enables greater control of fusion energy
Phys.org - 27 Oct 2016 22:50
Researchers working at the DIII-D National Fusion Facility at General Atomics (GA) have created an important new tool for controlling fusion plasmas that are hotter than the sun.
Launching fusion reactions without a central magnet, or solenoid
Phys.org - 27 Oct 2016 22:49
The tokamak is an experimental chamber that holds a gas of energetic charged particles, plasma, for developing energy production from nuclear fusion. Most large tokamaks create the plasma with solenoids--large magnetic c...
Steering a fusion plasma toward stability
Phys.org - 27 Oct 2016 22:49
Plasmas in fusion-energy producing devices are gases heated to millions of degrees that can carry millions of amperes of current. These superhot plasmas must be kept away from material surfaces of the vacuum vessel that ...
Bioluminescent sensor causes brain cells to glow in the dark
Science Daily - 27 Oct 2016 22:43
A new kind of bioluminescent sensor causes individual brain cells to imitate fireflies and glow in the dark. The probe is a genetically modified form of luciferase, the enzyme that a number of other species including fir...
Fusion reactor designs with 'long legs' show promise
Phys.org - 27 Oct 2016 21:04
Magnetic fusion is all about managing the interface between hot plasma and ordinary materials. The strong magnetic field in a tokamak--the vessel used in this fusion approach--is a very effective insulator; it is able to...
From Germany comes a new twist for fusion research
Phys.org - 27 Oct 2016 20:53
This past year saw the commissioning and initial operation of a new large-scale plasma experiment, the Wendelstein 7-X (W7-X) in Greifswald, Germany. Designed, constructed, and operated by the Max-Planck Institute for Pl...
Extinguishing a fusion fire in a flash of light
Phys.org - 27 Oct 2016 20:39
Fusion energy researchers have discovered that they can rapidly extinguish and cool a magnetically confined fusion plasma hotter than the center of the sun by injecting a large quantity of neon gas to prevent damage to f...
Battle hymns and lullabies: Scientist sheds new light on how dendritic cells conduct the T cell orchestra
Science Daily - 27 Oct 2016 20:35
New findings about how the immune system directs T cells to learn tolerance for the body's own cells have been reported by researchers in a new report.
Researchers use video gamelike test to study learning and recovery in stroke patients
Science Daily - 27 Oct 2016 20:35
A robotic arm and a virtual game were essential tools in a new study that suggests that while training doesn't change neurological repair in chronic stroke patients, it can indeed help such patients learn new motor skill...
Clinical trial data sharing off to a slow start
Science Daily - 27 Oct 2016 20:35
For many years, doctors, scientists and researchers have urged that clinical drug trial data be shared to accelerate medical advances in treating multiple diseases. But two years after free patient data became available ...
Children with autism may be over-diagnosed with ADHD, new study suggests
Science Daily - 27 Oct 2016 20:35
Pediatric researchers report that children with ASD may mistakenly be diagnosed with ADHD because they have autism-related social impairments rather than problems with attention. This is important for understanding what ...
Shifting epidemiology in drug-resistant organisms, large integrated health outcomes study reveals
Science Daily - 27 Oct 2016 20:33
A first-of-its-kind study of 900,000 hospital admissions from an integrated health system has yielded insights into shifts in the epidemiology of multi-drug resistant organisms (MDROs) in the community.
Senescent cells, atherosclerosis progression appear to be linked
Science Daily - 27 Oct 2016 20:33
Atherosclerosis is a disease in which arteries narrow due to plaques. That narrowing can lead to heart attacks and strokes -- both of which are leading causes of death in the U.S. Now, in paper shows that senescent cells...
Stability of exhausted T cells limits durability of cancer checkpoint drugs
Science Daily - 27 Oct 2016 20:33
Reinvigorating exhausted T cells in mice using a PD-L1 blockade caused very few T memory cells to develop. After the blockade, re-invigorated T cells became re-exhausted if antigen from the virus remained high, and faile...
Vitamin d supplements for pregnant women should be customised to the individual to ensure benefits are felt
Science Daily - 27 Oct 2016 20:33
Vitamin D supplements are less effective at raising vitamin D levels in pregnant women if they deliver their babies in the winter, have low levels of vitamin D early in pregnancy or gain more weight during pregnancy, a n...
Male birth control shots prevent pregnancy
