Relativistic effects play major role in neutron star mergers

A powerful numerical simulation reveals that gravitational waves from merging neutron stars can be detected by highly specialized detectors. The simulation, which included relativistic radiation reactions, showed tidal arms forming during the merger, significantly altering the dynamics and energy of the event.

Lowering 'bad' cholesterol as good or better than angioplasty for mild coronary artery disease

The study found that aggressively lowering 'bad' cholesterol with atorvastatin reduced ischemic events by 36% compared to balloon angioplasty, delaying cardiac events in patients with stable coronary artery disease. Researchers concluded that this therapy is a safe and effective initial strategy for reducing ischemic events.

Eating proper foods at right time after exercise can speed recovery

Researchers at the University of Illinois found that consuming foods containing leucine immediately after intense workouts can stimulate muscle protein synthesis and improve recovery. The optimal dosage is unclear, but athletes are advised to consume a balanced diet with protein-rich food and carbohydrate-rich fluids.

Search engines biased, out-of-date, and index no more than 16% of the web

A new study by NEC Research Institute reveals that search engines have decreased coverage to 16% of the publicly indexable web, with bias towards popular and commercial sites. The study also found that indexing can take months for new pages, affecting economic viability, scientific progress, and social decisions.

Bullying more common in middle schools than many recognize

A recent survey found bullying behaviors among 80% of middle school students, challenging traditional notions of bullies and victims. The research emphasizes the importance of addressing the 'school climate' to effectively combat bullying.

Price for decreased acid rain may be increased global warming

A University of Illinois professor warns that decreasing sulfur dioxide emissions could exacerbate global warming by enhancing temperature changes in North America, Europe, and Asia. The studies used climate/ocean models to calculate the potential effects of reduced sulfur dioxide emissions on global-mean surface temperatures.

Mentored foster children learn to trust others, researchers find

Researchers found that foster children who receive mentors experience improvements in their peer relationships and develop trust. The study, published in the Journal of Research on Adolescence, sheds light on how mentoring works for foster youth. Preliminary findings suggest that longer-term mentoring relationships yield better outcomes.

Very thin polymer films still have the same stuff

A team of scientists discovered that polymer molecules in ultra-thin films of 14 nanometers retain their shape and size comparable to their bulk counterparts. This finding challenges previous simulations, which suggested minimal changes in molecular structure with decreasing film thickness.

Simulation uses quantum mechanics to understand nanoelectronics

Researchers at the University of Illinois developed a computer simulation to understand nanoelectronics, a field where single electrons control devices. The simulation explores the interplay between quantum mechanics and matter's granularity, enabling scientists to design and optimize next-generation nanoscale electronic devices.

Lensless camera captures three-dimensional images

The new camera system uses beam splitters and folding mirrors to capture sequence of snapshots as an object is rotated in front of the aperture. The images are then processed to form a 3D representation of the object, which can be displayed on a computer screen or in a virtual reality environment.

Sahara's abrupt desertification started by changes in Earth's orbit, accelerated by atmospheric and vegetation feedbacks

German scientists used a climate model to conclude that the Sahara's desertification began abruptly 5,440 years ago due to subtle changes in Earth's orbit. The resulting desertification had significant impacts on ancient civilizations, with some of the most severe changes occurring between 4,000 and 3,600 years ago.

Study suggests need for better pain management in newborns

Researchers found that premature infants respond to pain and can differentiate between more and less painful procedures. They recommend universal pain management in newborns to mitigate the effects of early procedural pain. Premature babies, even those born very prematurely, become more responsive to pain with age.

Formic acid found toward hot galactic molecular cores

Researchers have found dense clumps of formic acid in three interstellar molecular clouds, providing insights into the formation of complex molecules. The discovery could help identify regions where more biologically important molecules might be located, supporting future searches for glycine sources.

Researchers discover treatment that delays onset of insulin-dependent diabetes

Researchers at the University of Utah have discovered a naturally-occurring antibody that significantly reduces diabetic symptoms in mice. The study's findings suggest that masking the foreign nature of affected cells may prevent immunological processes that cause diabetes. Eighty percent of treated mice did not develop diabetic symptoms.
