New CSIRO soybean a hit in Japan

The Bunya soybean variety is gaining popularity in Japan due to its enhanced suitability as an ingredient in traditional Japanese dishes. Its unique gelation properties make it ideal for producing a range of soy-based foods like tofu and custard.

For post-boomers, public education worth more than Social Security and Medicare

A new study from UC Berkeley concludes that younger Americans are getting the better deal when factoring in public education as an intergenerational entitlement program. The researchers found that people born between 1972 and 2060 will make net gains of 4 to 6 percent over their lifetimes, while those now aged 63 to 80 have paid out mo...

Mount Sinai researchers discover genetic framework to explain and predict adverse drug reactions

Researchers at Mount Sinai School of Medicine have discovered a genetic framework that can explain and predict adverse drug reactions, including heart arrhythmias. The framework, developed by Ravi Iyengar and his team, uses genetic information to identify potential risks for arrhythmias in patients taking certain medications.

From wimp to jock: How a cell motor gets pushy

A University of Utah researcher helped discover how a protein motor works with two other proteins to move nerve cells and components inside them. Mutant LIS1 has been linked to the classic form of lissencephaly, a devastating brain malformation due to defective migration of nerve cells within the developing brain.

Odor pleasantness shown to be partly hard-wired

Researchers developed an algorithm that enables eNoses to rate novel odors on a scale of pleasantness, achieving high accuracy in predictions, and suggesting a fundamental cross-cultural similarity in odorant pleasantness. The study's findings may lead to new methods for odor screening and environmental monitoring.

Disabled UK children more likely to live in poverty

Research finds disabled children in the UK face higher levels of poverty and personal and social disadvantage compared to their non-disabled peers. The study, published in BMC Pediatrics, found that households with disabled children are more likely to rely on social security benefits and experience additional financial costs.

ADHD linked to interaction of genetics and psychology

A study found that children with ADHD exhibit more symptoms when they experience high levels of self-blame during inter-parental conflict, which is associated with genetic variations related to serotonin activity. The study suggests a synergistic effect between genetic and environmental factors in the development of ADHD.

The association between sleep disturbances and reduced quality of life varies by race

A recent study reveals that sleep disturbances have a significant impact on health-related quality of life, varying by race. For African-Americans, physical health-related quality of life is significantly worse than in Caucasians, while Hispanics experience greater mental distress due to snoring and insomnia symptoms.
