New research links brain structure to an individual's likelihood of experiencing hallucinations and to their musical aptitude. Participants with higher musical aptitude showed lower hallucination proneness.
A new study of four South Asian countries argues that early marriage should be considered a major public health issue, due to its complex associations with women's education, health and nutrition -- which may also affect the next generation of children. The study also finds that increased education has had some, but not enough, success in delaying girls' marriage.
Nanorods made of bismuth sulfide kill tumor cells with heat when they are irradiated with near-infrared light (NIR). Scientists are now making these weapons more powerful by remodeling the defect state of the nanorod crystal lattice by adding gold nanodots. This could be a good basis for more effective photothermal treatment of tumors.
Epidemiological studies show that in utero fetal infection with the Zika virus (ZIKV) may lead to microcephaly, an irreversible congenital malformation of the brain characterized by an incomplete development of the cerebral cortex. However, the mechanism of Zika virus-associated microcephaly remains unclear. Scientists have now identified a specific mechanism leading to this microcephaly.
Bacteria in lakes play a key role in maintaining water quality by absorbing excess nitrogen and phosphorus. They also help store carbon, which has implications for our climate. But, as it turns out, their ability to do these tasks varies depending on the makeup of the lake in which they live. In short, location matters most.
Although the insidious bacterium Salmonella typhi has been around for centuries, very little is actually known about its molecular mechanisms. A new study addresses this knowledge gap and may lead to novel, targeted treatments.
Sensory hair cells in the inner ear combine into hair bundles to convert sound waves into electrical signals. Both single-cell and organ-wide directionality are critical for hearing, but these two levels of organization are controlled by largely distinct molecular mechanisms during inner ear development. Researchers have identified a protein, Daple, that interacts with both systems and is a promising candidate to coordinate single cell and organ-wide directionality.
A cost analysis shows treatment plans that set individualized blood sugar goals for diabetes patients, tailored to their age and health history, can save $13,546 in health care costs over their average lifetime when compared with treatment strategies that stick to a uniform national standard.
The Chachapoyas region was conquered by the Inca Empire in the late 15th century. Inca oral histories, written down after the Spanish conquest, claim that the native population was forcibly resettled out of Chachapoyas and dispersed across the Inca Empire. However, a new study uses genetic evidence to reveal that despite Inca conquest, the population of Chachapoyas has remained genetically distinct, and not assimilated with that of the Inca heartland.
Scientists have studied the vibration of four gases using electron microscopy and spectroscopy. Combined with simulations, they measured the increased vibration at 1,000°C compared with room temperature. O2 and CH4 showed significant excitation, although the vibration of hot O2 was overestimated by the simulations. N2 and CO showed no increase in vibration, because of rigid bonds. The method can be used to design efficient gaseous reactions.
Immune responses and the regulation of autoimmunity are affected by the time of day when the response is activated. There may be important differences in time-of-day response to drugs used to treat autoimmune diseases such as multiple sclerosis.
Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta.
In remote Italian villages nestled between the Mediterranean Sea and mountains lives a group of several hundred citizens over the age of 90. Researchers have identified common psychological traits in members of this group.
