Scientists use Chandra to observe the Northern Lights dancing in X-ray light, revealing changing bright arcs of energy above the Earth's surface. The team detects low-energy X-rays generated during auroral activity, expanding our understanding of solar storms and their impact on the planet.
The Office of Naval Research has successfully tested a fast scramjet, reaching speeds of Mach 5.5 and demonstrating the feasibility of low-cost flight test techniques at hypersonic speeds. The engine, powered by liquid fuel, offers a safer alternative to other designs, making it suitable for shipboard use.
Researchers have developed a new approach that boosts the production of TAP, an immune system component, to make smaller vaccine doses more effective, reducing side effects and increasing immunization capacity. This technique has the potential to far-reaching benefits in the field of vaccines.
A recent study found that frequent verbal harassment in middle school is associated with a three-fold increase in alcohol use during high school. The researchers also discovered that peer harassment fuels aggression and antisocial behaviors among boys, particularly those who experience both verbal and physical harassment.
A study by Wake Forest University found that Latino men experiencing family-related ambivalence during migration are more likely to suffer from anxiety. The researchers suggest enhancing communication between migrants and their families could help address mental health needs.
Climate change and human activities are pushing tiny pikas to higher elevations, leaving them with limited habitat options. The animals' distribution has diminished significantly over the past 40,000 years, with many populations now isolated on separated mountain ranges.
A Mayo Clinic study found that vertebroplasty significantly improved back pain and activity levels in patients with vertebral compression fractures. Patients' pain during rest and activity improved an average of seven points one week after treatment and remained improved for up to a year.
The Office of Naval Research has developed a technology that allows binoculars to transmit digital voice over long distances, up to five nautical miles. LightSpeed can also be used for communication between ships at sea and platforms in the air and on the ground.
Scientists have identified two microRNAs, miR-1 and miR-133, that play opposing roles in determining whether myoblasts proliferate or differentiate into mature muscle cells. Increasing miR-1 promotes differentiation, while increasing miR-133 enhances proliferation.
A recent study found that stopping regular blood transfusions in children with sickle cell disease who are at risk for a stroke means their stroke risk likely returns. The study, which involved 41 children, showed that within a few months of halting transfusion, 14 children resumed at-risk status and two had strokes.
J. Virgil Waggoner is being recognized by the Chemical Heritage Foundation for his outstanding contributions to the petrochemical industry, as well as his commitment to education and community service. He will receive the Petrochemical Heritage Award at the opening of the 31st annual NPRA International Petrochemical Conference.
The study found MDCT angiography to be a reliable tool for evaluating the coronary veins prior to pacemaker lead placement and other procedures. It improves diagnosis quality by providing better planning before surgery, making it a valuable alternative to conventional angiography.
Researchers developed a new approach to analyze drug effectiveness data, providing insights into the cost-effectiveness of newer and older anti-epileptic drugs. The study suggests that two older drugs, valproate and carbamazepine, are likely to be more cost-effective for newly diagnosed patients with partial seizures.
