A new comprehensive study of Australian natural hazards paints a picture of increasing heatwaves and extreme bushfires as this century progresses, but with much more uncertainty about the future of storms and rainfall.
A drug that is showing some early promise in efforts to prevent pre-term birth has been successfully tested by a team of investigators.
Researchers have not only built microelectromechanical systems (MEMS) devices the size of insects, but have also created them to move just like real insects.
To better understand why some people adapt well to life at high altitude while others don’t, researchers studied red blood cells derived from representatives of both groups living in the Andes Mountains. The study reveals that high-altitude, low-oxygen dwellers prone to chronic mountain sickness produce massive amounts of red blood cells thanks to overproduction of the enzyme SENP1.
Researchers have identified several new biological markers to measure the progression of the inherited neurodegenerative disorder Huntington’s disease. Their findings could benefit clinical trials that test new treatments for the disease.
Vitamin D deficiency is associated with an increased risk of developing bladder cancer, according to a systematic review of seven studies. Though further clinical studies are needed to confirm the findings, the study adds to a growing body of evidence on the importance of maintaining adequate vitamin D levels.
Ophthalmologist emphasizes care in dim-light driving as time change brings darkness to evening commute
As the end of daylight saving time draws near, ophthalmologists want to focus on a real issue—dim-light driving situations that can endanger drivers and pedestrians.
Older adolescents and adults can learn certain thinking skills including non-verbal reasoning more effectively than younger people, report researchers.
Scientists are driving three-wheeled, single-molecule "nanoroadsters" with light and, for the first time, seeing how they move.
Succeeding in the male-dominated science, technology, engineering and mathematics (STEM) disciplines can be very challenging for female faculty. Now, a study of the collaboration patterns of STEM faculty has found that the playing fields in some disciplines are not as level as they first appear.
Isolates of a common poultry pathogen collected from animals in Indian bird markets were found to be mostly resistant to multiple classes of antibiotics. The study provides the first data on prevalence and isolation of Helicobacter pullorum in India.
It may be famous for hosting spectacular sights such as the Tucana Dwarf Galaxy and 47 Tucanae (heic1510), the second brightest globular cluster in the night sky, but the southern constellation of Tucana (The Toucan) also possesses a variety of unsung cosmic beauties.
A new imaging technique stimulates particles to emit laser light and could create higher-resolution images of living tissues, say scientists.
NASA's Magnetospheric Multiscale mission, or MMS, is breaking records. MMS now holds the Guinness World Record for highest altitude fix of a GPS signal. Operating in a highly elliptical orbit around Earth, the MMS satellites set the record at 43,500 miles above the surface. The four MMS spacecraft incorporate GPS measurements into their precise tracking systems, which require extremely sensitive position and orbit calculations to guide tight flying formations.
While China is building a gigantic modern-day upgrade of the famed ancient Silk Road resplendent in global cooperation in the name of economic expansion, a group of sustainability scholars point out that the Belt and Road Initiative (B&R) also could be a superhighway of environmental progress.
Never before have astrophysicists measured light of such high energy from a celestial object so far away. Around 7 billion years ago, a huge explosion occurred at the black hole in the center of a galaxy. This was followed by a burst of high-intensity gamma rays. A number of telescopes have succeeded in capturing this light. An added bonus: it was thus possible to reconfirm Einstein's General Theory of Relativity, as the light rays encountered a less distant galaxy en route to Earth -- and were deflected by this so-called gravitational lens.
For millennia, philosophers have struggled to define human consciousness. Now, a team of researchers has pinpointed the regions of the brain that may play a role maintaining it.
Twelve weeks of aerobic exercise significantly boosted testosterone levels in overweight and obese men, according to researchers. Increased levels were highest among men who exercised vigorously, report investigators.
Researchers find that people who were relatively tall as teens are more likely to invest in stocks, and those who were overweight are more risk-averse and less likely to participate in the market.
Researchers provide unprecedented evidence that basal forebrain pathology precedes and predicts both entorhinal pathology and memory impairment in people with Alzheimer's disease.
