A team of astronomers, including an undergraduate researcher, detect the presence of massive stellar explosions in a distant galaxy using quasar light. The discovery reveals six super bubbles formed at nearly the same time, releasing energy equivalent to 10,000 suns over their lifetimes.
A six-year study of people aged 40-70 found that those with diabetes and high blood pressure experience greater cognitive decline compared to their healthy counterparts. The study suggests controlling hypertension and diabetes before age 60 may help preserve mental abilities later in life.
Frank Shu, a renowned expert in theoretical astrophysics and star formation, received the Dannie Heinemann Prize for his groundbreaking research on various topics including spiral structure, stellar dynamics, and planetary rings. The award recognizes his significant contributions to the field of astrophysics.
Astronomers have discovered intriguing patterns of star motion and composition that suggest a remnant of a smaller galaxy consumed by the Milky Way billions of years ago. The study, part of the 2dF Old Stellar Population Survey, aims to investigate the galactic merger that formed the Milky Way's thick disk.
Astronomers have discovered over 154 rapidly moving stars towards the center of the Milky Way and its brightest neighboring galaxy. The findings are significant as these stars were previously difficult to detect due to their extreme density, allowing scientists to gain insights into the galaxy's most densely packed regions.
Yale astronomers have discovered that the area around the Milky Way contains remains of small galaxies torn apart by gravity, contradicting previous smooth distribution theories. The study found approximately 150 RR Lyrae variables with proper periods and light variations in a previously surveyed region.
The Stardust spacecraft is set to receive a gravity boost from Earth, lengthening its orbit and setting it on course for a rendezvous with comet Wild 2. The spacecraft will capture particles being boiled off the comet's surface by solar heating.
A Penn State study found that restricting foods has negative effects on children's self-esteem, particularly among overweight girls as young as 5 years old. The research suggests that parents' concern about their daughter's weight and restriction of food access can lower perceived physical and cognitive ability.
A study published in Radiology found that women who receive further testing on the same day as an abnormal screening mammogram experience significantly less stress than those who have to wait. The researchers also found that offering immediate diagnostic imaging can reduce the stress of a false positive mammogram, but would increase ov...
Researchers at CSIRO Australia have developed a new preservative treatment method using supercritical carbon dioxide, which penetrates wood more effectively than conventional techniques. This process offers environmental and economic benefits, including reduced capital costs and no residual solvent problems.
