Using extremely faint light from galaxies 10.8-billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice of the adolescent universe. The map shows a web of hydrogen gas that varies from low to … Continue reading
The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research predicts.
A new study offers compelling evidence that inflammation may be the link between vitamin D and prostate cancer. Specifically, the study shows that the gene GDF-15, known to be upregulated by vitamin D, is notably absent in samples of human … Continue reading
New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the … Continue reading
Scientists have revealed that feather shafts are made of a multi-layered fibrous composite material, much like carbon fiber, which allows the feather to bend and twist to cope with the stresses of flight. Since their appearance over 150 million years … Continue reading
Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. Carbon nanotubes have been touted as exceptional materials with unique properties that allow for extremely efficient charge and energy … Continue reading
The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter captured views of comet C/2013 A1 Siding Spring while that visitor sped past Mars on Sunday (Oct. 19), yielding information about its nucleus.
NASA’s Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian … Continue reading
Physicists report that they’ve used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly … Continue reading
For the last 20 years, scientists have tried to design large DNA crystals with precisely prescribed depth and complex features — a design quest just fulfilled by scientists. The team built 32 DNA crystals with precisely-defined depth and an assortment … Continue reading
Sequencing the DNA of children with mystery genetic disorders produced a definitive diagnosis in 40 percent of one hospital’s most complex cases — a quantum leap from the field’s 5-percent success rate 20 years ago.
The migration of millions of birds across the face of the planet is one of nature’s greatest annual events. Every spring some species move in one direction, while every autumn those same species move in the opposite one, very often … Continue reading
People who play action video games such as Call of Duty or Assassin’s Creed seem to learn a new sensorimotor skill more quickly than non-gamers do, psychology researchers have found.
Among patients with an autoimmune disease called ANCA-associated vasculitis, autoantibody increases were linked with an 11-fold increased risk of relapse in patients whose kidneys were affected, a study concludes. Among patients without kidney involvement, such increases were associated only weakly … Continue reading
