Giant hummingbirds use more energy for their body size than smaller hummingbirds do, but still below the upper metabolic limit. Asexual fish hybrids have lower physiological performance, possibly due to increased reproductive advantage over sexual dace. Small sea birds hold heat rather than increasing metabolism

A study found that young black males with male partners have twice the number of new HIV infections as other demographics, likely due to cultural beliefs about masculinity influencing condom use and HIV risk assessment. These cultural norms may lead to increased risk behavior with perceived 'masculine' partners.
A pair of Indiana University scientists analyzed regional climate models to assess future wind patterns in the US. They found that most areas will see little or no change in wind density, with high wind potential over the Great Lakes and parts of Mexico.

A study of 367 mothers and infants found that prenatal exposure to BPA was associated with an increased risk of wheezing in childhood, particularly among the youngest group. High levels of BPA detected in women at 16 weeks' gestation were linked to wheeze in their offspring, but not after 3 years of age.
Research suggests that screening very preterm infants for autism spectrum disorder (ASD) at 18 months of age is often inaccurate and can lead to false positives. In contrast, waiting until 30 months of age may provide a more accurate assessment. A study found that only 3% of infants who screened positive on all three screens at 30 mont...

After 10 years, men taking aspirin had a 31% lower rate of biochemical failure compared to non-aspirin users.
Research suggests that obese pregnant women have impaired immune function, leading to fewer cells and proteins that help fight infections. This could have serious consequences for both the mother and newborn.
A new oral hygiene approach called Managing Oral Hygiene Using Threat Reduction (MOUTh) has been developed to help nurses care for dementia patients who resist care due to perceived threats. The technique focuses on making the patient feel comfortable and reducing threat perception, resulting in improved oral health outcomes.
A Yale study found that young children often acquire motor skills to unbuckle before developing cognitive understanding of restraints, posing a safety hazard. The study also revealed that 43% of self-unbuckling children use a five-point restraint, and parents often respond with immediate action when their child unbuckles while in motion.
A study by the American Academy of Pediatrics reveals that children under 6 years old often unbuckle themselves from car seats while in motion, tripling their injury risk. Parents frequently pull over and re-buckle their children, but this behavior highlights a need for safer restraint devices.
University of Cincinnati researchers have discovered the molecular system involved in weight gain linked to a class of diabetes drugs, finding it's also triggered by high-fat foods. The study may lead to modification of existing therapies and dietary recommendations.
The Baryon Oscillation Spectroscopic Survey (BOSS) has created the biggest 3-D map of the distant universe, using light from 14,000 quasars. The map demonstrates that it is possible to determine variations in the density of intergalactic hydrogen gas at cosmological distances and measure the effects of dark energy.
A study by the American Academy of Pediatrics found that many parents with smoking habits in cars have a hard time enforcing no-smoking rules. The result is that children are exposed to toxic chemicals, which may cause severe asthma attacks and respiratory infections.
Research found that exposure to secondhand smoke is associated with increased blood pressure in boys, while girls showed lower blood pressures. The study suggests that preventing children's exposure to tobacco smoke is an important cardiovascular health measure.
A new study confirms that infants wake up taller after sleep, with longer sleep bouts predicting increased weight and body-fat composition. The research also found sex differences in sleep patterns related to growth, with boys exhibiting more sleep bouts and shorter ones than girls.
