Scientists develop greater accuracy in recording baby’s heart rates in the womb

Researchers have developed a new test that can accurately record baby's heart rates in the womb in just 20 minutes, allowing doctors to monitor health and detect potential arrhythmias. The technique uses sophisticated filtering and signal processing technologies to pick out the baby's heart signal from background interference.

Elementary schools need a lesson in bathroom breaks

A University of Iowa Health Care study found that public elementary school teachers often restrict young students' access to the bathroom, despite it being a common issue. Teachers with more experience were better equipped to recognize bladder problems and involved school nurses in addressing them.

Weizmann Institute scientists report why taste and smell differ among individuals

Weizmann Institute scientists found that around 50 genes are optional, affecting a person's unique pattern of active olfactory receptors. This high level of genetic variation impacts how thousands of aromas and flavors are perceived. The study also shows varying levels of obliteration among different ethnic groups.

UCSD biologists discover key step for 'designer plants' that could clean up heavy metals

Researchers at UCSD have discovered a chemical that allows plants to transport phytochelatins from roots to stems and leaves, enabling them to detoxify heavy metals like lead, arsenic, and cadmium. This finding brings bioremediation, using plants to clean up contaminated soil, closer to reality.

Salk news: gene therapy for Lou Gehrig's disease

Researchers found that injecting a gene producing insulin-like growth factor-1 (IGF-1) into muscles delayed disease onset by 31 days, preserved nerve cells, and reduced muscle wasting. This study may lead to a new, gene-based treatment for ALS affecting over 30,000 Americans.
