Nearly one-third of US parents don't know what to expect of infants

A recent study reveals that nearly one-third of US parents have low-level knowledge of typical infant development, resulting in impaired parent-child interactions. This false parenting assumption can rob kids of cognitive stimulation, as parents often misinterpret behaviors and set unrealistic expectations for their child's growth.

Children more vulnerable to harmful effects of lead

A study found that children's blood lead concentrations at age 6 are associated with reduced IQ and gray matter volume in the prefrontal cortex, highlighting a critical period of vulnerability. Research suggests that even lower levels of lead exposure can result in measurable deficits in cognitive development and behavioral problems.

Scientists identify genomic 'fingerprint' for alcohol-induced heart failure

Researchers have discovered a unique genetic profile associated with alcohol-induced heart failure, which could enable earlier diagnoses and monitor clinical outcomes. The study's findings offer new hope for addressing this condition, particularly when caught early through aggressive intervention.

Bacterial slime helps cause serious disease

Leptospirosis is a major public health problem in South East Asia and South America, with over 500,000 severe cases every year. Researchers have discovered that bacteria can form biofilms, which protect them against harsh conditions and make them more resistant to antibiotics.

Melting defects could lead to smaller, more powerful microchips

Princeton engineers have created a process that can literally melt away tiny defects on microchips, enabling precise shaping of components without increasing fabrication cost. The method, called Self-Perfection by Liquefaction (SPEL), uses a light pulse from an excimer laser to guide the resulting flow of liquid into desired shapes.

Turning fungus into fuel

A team of researchers has decoded the genetic sequence of Tricoderma reesei, a fungus that can break down plant fibers into simple sugars. This finding could unlock possibilities for industrial processes that convert corn, switchgrass, and cellulose-based waste into ethanol.

Scientists discover why plague is so lethal

Bubonic plague bacteria produce excessive aspartic acid due to missing enzyme, contributing to its high lethality. Researchers found that a single genetic mutation in Yersinia pestis leads to this imbalance.

Alcoholism is not just a 'man's disease' anymore

Researchers found substantial increases in drinking and alcohol dependence among women, particularly white and Hispanic women, between 1991 and 2002. The study suggests that social acceptability of women's drinking increased, leading to a rise in alcohol dependence, especially among those who drank.

Gene sequence that can make half of us fatter is discovered

Researchers have identified a gene sequence associated with an expanding waist line, weight gain, and insulin resistance, affecting half of the UK population. The sequence is more common in Indian Asians than Europeans, providing a possible genetic explanation for the high levels of obesity and diabetes in this group.

Getting wise to the influenza virus' tricks

Researchers at EMBL and CNRS identified the key protein domain responsible for binding to host RNA molecules, allowing the virus to multiply. The PB2 cap-binding site is a promising target for designing mimics of the cap that would inhibit viral replication.

Mothers less likely to pursue HPV vaccination for youngest daughters

A recent study found that US mothers are less likely to vaccinate their youngest daughters against human papillomavirus virus (HPV), even though the vaccine is recommended for girls aged 11 and 12. The researchers identified key factors associated with intention to vaccinate, including beliefs about HPV vaccination and perceived benefits.

A safer alternative to aspirin?

A study published in The Lancet Neurology found that cilostazol is as effective as aspirin in preventing recurrent stroke, but causes fewer bleeding events. This suggests that cilostazol could be a more effective and safer alternative for Chinese patients with ischemic stroke.

Controlling embryonic fate by association

Researchers at Baylor College of Medicine found that the association between Nanog and Oct4 proteins with transcription repression complexes determines embryonic stem cell fate. The complex, called NODE, contains histone deacetylases that control gene expression.

Second genetic link to weight and obesity

A recent study published in Nature Genetics has identified two new genetic variants associated with fat mass, weight, and risk of obesity. The variants, located near the MC4R gene, act in addition to previously described FTO gene variants, resulting in an average increase of 3.8 kg (or 8.5 lb) in weight.
