The study found that one in five women seeking treatment desired multiples over having a singleton, while fewer knew about the increased risk of cerebral palsy and infant death for twins. Infertile couples view twins as a 'bonus' to quickly build their families, but this increases risks such as preterm delivery.
Researchers challenge traditional views on volcano eruptions, finding evidence that giant eruptions are significantly less likely than previously thought. They discovered that plutons, which form beneath volcanoes, are built by small molten intrusions over millions of years.
Researchers sequenced genetic material from a new strain of SIV in chimpanzees near Kisangani, Democratic Republic of Congo. The new strain is not related to HIV-1 and confirms that HIV-AIDS did not originate from oral polio vaccines.
Researchers discovered a protein, H2-DM, that helps distinguish between foreign and native proteins in the immune system. This distinction is crucial to prevent autoimmune conditions like diabetes, lupus, and arthritis.
The Cancer Survivors Center will provide care management programs to monitor treatment side effects and offer training programs for teachers and coaches. Pediatric cancer survivors will also receive parent and sibling counseling, as well as special sports/training programs to re-enter their active lives.
The Arecibo telescope has been made more sensitive with the addition of the ALFA instrument, allowing for faster sky surveys and improved detection of pulsars and other rare celestial phenomena. The new device will also enable astronomers to map the neutral hydrogen gas in our galaxy and others.
A simple, inexpensive blood test performed at birth can screen for immune disorders like SCID and increase survival rates. The test, which costs $50, identifies infants with a profound deficiency of lymphocytes and has been shown to be effective in identifying children with other immune disorders.
Scientists have successfully measured the activity of a single granule cell in an intact brain using patch-clamping technique, confirming predictions made over 30 years ago by David Marr. This breakthrough could lead to better understanding and treatment of movement disorders like ataxia and dysmetria.
Researchers predict a 10-degree Celsius shift in Jupiter's average temperature as atmospheric whirlpools vanish, causing jet streams to become unstable. This will spawn new vortices and signal the end of Jupiter's current 70-year climate cycle.
A recent study found that mycophenolate mofetil reduces intimal thickening and improves long-term outcomes for heart transplant patients compared to azathioprine. The study used a site-to-site IVUS analysis of 196 patients, showing significantly less progression of vascular disease in CellCept-treated patients.
Jacobson's solid oxide fuel cell research has the potential to improve how electricity is generated, making it less expensive and more environmentally friendly. His goal is to investigate different materials used as components in fuel cells to make reactions work at lower temperatures.
A new study published in the American Journal of Hypertension demonstrates that 15 minutes of daily RESPeRATE treatment significantly reduces home blood pressure in both medicated and non-medicated patients. The study also shows high patient compliance, with many patients continuing treatment after the trial ended.
A team of geologists has discovered evidence of at least three Cryogenian glaciations, with ages estimated to be around 663 million years ago. The new findings confirm a previously hypothesized 'snowball Earth' scenario and suggest significant climate changes may have led to extinctions.
The 2003 Starting Salary Survey shows a shift in employment patterns among new chemistry Ph.D. graduates, with more taking lower paying academic positions. Median salaries were lower than previous classes, with bachelor's graduates still below the all-time high.
Studies show that the Curves program leads to significant weight loss, increased muscle mass, and improved health markers such as blood pressure and aerobic fitness. Women participating in the program experience a 20-30% improvement in strength and a 15% increase in aerobic capacity.
A comprehensive study of plant physiology has found that fast-growing plants (hares) are more susceptible to pollution, while slower-growing plants (tortoises) are better adapted to control energy consumption. The research provides insights into how plants respond to environmental changes.
Researchers used advanced technology to study Weddell seals' hunting habits and physiological adaptations. They discovered that these extreme athletes can survive for hours by catching and eating prey, providing insights into conservation efforts.
A new electronic relationship between physicians and patients will enable seamless sharing of knowledge, responsibility, and decision-making. The growth of electronic communication options offers opportunities for enhanced doctor-patient relationships, increased patient safety, and improved healthcare outcomes.
Penn State's new thermoacoustic chiller uses helium gas to keep ice cream in delicious condition without damaging the atmosphere. The technology has potential for widespread use in applications where chemical refrigeration is difficult or banned due to global warming.
Researchers at UNC Chapel Hill are working on a new program to improve employment in long-term care facilities, focusing on recruitment and retention strategies, including better pay, recognition, and training. The project aims to address staffing shortages and improve the quality of life for nursing home residents.
Researchers at U-M and Amherst College used chemical signatures of water to identify areas with microbial gas deposits, a relatively inexpensive analytical tool compared to other methods. This method has potential not just in Michigan but also globally for finding natural gas resources.
Researchers recorded mantis shrimp's club-shaped front leg striking prey at peak speeds of 23 meters per second, generating forces over 100 times the shrimp's body weight. The unique saddle-shaped structure acts as a spring, storing energy until release propels the strike.
Drs. Thal and Nitsch receive the Potamkin Prize for their groundbreaking research on effective therapies to treat and prevent Alzheimer's disease. Their work has revitalized hopes for a vaccine and slowed cognitive decline in patients.
