NIST quantifies low levels of 'heart attack risk' protein

Researchers at NIST have developed a method to quantify extremely low levels of C-reactive protein (CRP), a molecule that indicates cardiovascular disease risk. The new certified reference material will improve the accuracy of clinical laboratory tests for CRP, enabling more precise detection of individuals at high risk of heart attack.

Mobile microscopes illuminate the brain

Scientists at Max Planck Institute for Biological Cybernetics create tiny laser-scanning microscope images brain cells in awake and moving animals, eliminating the need for electrodes. This breakthrough allows researchers to study how the brain generates an internal representation of the outside world.

Preschoolers challenge stereotypical gender roles

Research from the University of Gothenburg reveals that preschool children actively challenge and redefine traditional gender structures. Despite teachers' biases, children often share play and learning activities, show concern for each other's well-being, and reformulate possibilities through child-led initiatives.

Long-term follow-up shows Mexico's conditional cash transfer program confers health benefits on children, especially those of mothers with no education

A long-term follow-up study found that Mexico's Oportunidades program conferred health benefits on children, particularly those whose mothers had no formal education. The additional 18 months of inclusion in the program reduced socioemotional problems and improved child growth, especially for those with mothers who were less educated.

Study: Lap band surgery effective for morbidly obese children

A new study published in the Journal of the American College of Surgeons found that laparoscopic adjustable gastric banding (Lap band) surgery improves the health of morbidly obese adolescents. The procedure led to significant weight loss and reduced the risk of developing insulin resistance, a key indicator of obesity-related illnesses.

Sustainably grown garlic

A recent study identifies stable and variable traits in garlic cultivars, providing guidelines for farmers and new options for consumers. The research suggests that bulb size, color, and elemental composition are site-dependent and highly variable, offering promise for savvy consumers seeking locally grown garlic varieties.

New theory on fairness in economics targets CEO pay

A new theory proposes a method to determine fair CEO compensation using information theory and statistical thermodynamics. The ratio of CEO pay to the lowest employee salary has increased significantly in recent years, with US CEOs averaging around 344-to-1, raising questions about market efficiency.

Radiation therapy technique successfully treats pain in patients with advanced cancer

Researchers at the University of Pittsburgh Cancer Institute successfully treated pain in patients with advanced cancer using stereotactic radiosurgery (SRS). The study found that SRS was a safe and effective treatment for patients with bone metastases, offering faster onset of pain relief and longer survival rates compared to conventi...

Longer toes, unique ankle structure aid sprinters

Researchers found that sprinters have significantly shorter lever arms in their ankles compared to non-sprinters. This allows muscles to produce greater force without sacrificing speed. The study suggests that a unique foot structure is essential for sprinting success, with longer toes providing an additional advantage.

Study examines associations between antibiotic use during pregnancy and birth defects

A study examined associations between antibiotic use during pregnancy and birth defects, finding that certain antibiotics like sulfonamides and nitrofurantoins may be associated with severe birth defects. Many commonly used antibiotics, such as penicillins and cephalosporins, were not linked to an increased risk of birth defects.
