The survey shows strong support for indexing the retirement age to increases in life expectancy. However, actuaries opposed individual accounts and favored limiting investment choices if enacted. Most respondents disagreed with adjusting benefits based on retiree-to-worker ratio.
Researchers discovered a genetic mutation responsible for a rare form of treatable dwarfism, affecting 105 family members in northeastern Brazil. The study suggests the mutation could be used as a prenatal screening test for the disorder.
Decentralized energy technologies, such as solar and wind power, are being implemented in developing countries to address electricity shortages. The symposium aims to discuss recent developments and barriers to the wider adoption of renewable energy sources.
Researchers discovered Wnt-4's role in regulating kidney development through inducing tubulogenesis in isolated mesenchyme. Additionally, Wnt-4 suppresses male cell fates in female embryos, affecting sex organ differentiation. It also mediates tissue interactions involved in neuronal growth and axonal guidance.
Researchers at HHMI and Stanford University have developed a new method to engineer drug molecules that bind more effectively to their targets. By attaching small molecule inhibitors to larger proteins, the team increased the binding affinity of the inhibitor, making it easier to inhibit protein-protein interactions.
A new type of degradable polyethene, SPI-TEK, breaks down in five years and allows other organic materials to decompose, increasing landfill site capacity. Bayer is also testing a new 100% degradable polyester suitable for industrial production in agriculture and food sectors.
A University of Michigan cancer vaccine combination with interleukin-2 was found to be effective in mobilizing the immune system to attack and destroy malignant cells. Eighty percent of mice showed complete regression of their tumors after treatment.
A new technology using coated alumina could reduce emissions from small sources, such as industrial boilers and lawn mowers. The technique removes 95% of nitrogen oxides under conditions similar to combustion exhaust.
Researchers found that contaminants can have very little impact on the physical properties of plastics, allowing for more functional products to be made from recycled materials. This could increase production of recycled plastic products like car bumpers and street furniture.
The new high-strength, ultra-thin steels are being tested for endurance on life-size testing rigs to simulate 40,000km of rocky road driving. The materials range in thickness from 0.7 to 2 mm and have improved fatigue properties.
Researchers have found a secondary barrier in the brain that prevents certain drugs from reaching tumors and neurological disorders. The barrier is called the basement membrane and traps stealth agents while allowing others to pass through, highlighting challenges for gene therapy and drug delivery.
A University of Michigan study found that seniors who volunteer for less than an hour a week are more likely to live longer. The study analyzed data from 1,211 older adults and discovered that volunteering is directly associated with increased survival rates, rather than just being a result of better health.
A study by Johns Hopkins Medicine reveals that nearly 90% of prostate cancers are linked to a common genetic process called 'gene switching,' which can be reversed with drugs. This finding has the potential to correct one of the most common cancers in men without using typical gene therapy.
Researchers link Fas and FasL interaction to immune-privilege in the eye, affecting age-related macular degeneration. Deficiency of Fas or FasL leads to increased growth of new retinal vessels.
Researchers at Sandia National Laboratories have developed a decontamination foam that can neutralize chemical and biological agents in minutes. The foam, called Decon Foam 100, is made from ordinary household products and could be dispensed immediately after an attack, even before evacuating casualties.
