How the brain sends eyeballs bouncing

Researchers Robert Schafer and Tirin Moore studied how the frontal eye field generates saccades, finding that attentional circuitry governs motor circuitry. The study used eyetracking and microstimulation to analyze saccade patterns, revealing a mechanism for attention to modulate saccade motor commands.

Scientists enhance Mother Nature's carbon handling mechanism

Researchers developed a method to accelerate removal of carbon dioxide from the atmosphere and store it in oceans for centuries, mimicking nature's natural weathering process. This new technology may counteract acidification of oceans threatening coral reefs and provide a feasible solution for reducing global warming.

Progress toward new therapies for coronary artery disease

Researchers at Burnham Institute for Medical Research have discovered that stimulation of the Wnt signaling pathway is essential for coronary vasculature formation. The study provides a new avenue for developing therapies for coronary artery disease, which is a leading cause of mortality in Western countries.

Indiana University research at Neuroscience 2007

Researchers at Indiana University found that women's brains respond differently to male faces depending on the menstrual cycle stage. During ovulation, their brains show more activity in areas related to rewards and less activity in areas associated with inhibition. Additionally, training has been shown to improve balance in older adul...

When to have a child? A new approach to the decision

Researchers developed a logical decision model to help women weigh the benefits of motherhood against its effects on career and social interests. The model suggests that having a child at a younger age may be better for women in their early careers, as taking a maternity leave has less impact on future career prospects.

Energy from hot rocks

Researchers from UC Davis and international partners aim to unlock geothermal energy potential in Iceland and the US. By studying high-pressure conditions and heat transfer processes, they hope to develop more efficient methods for extracting heat from rocks.

Evolution and fly genomics

New fly genomics research provides a comprehensive view of adaptive protein evolution, revealing the role of adaptation in evolution and human genome uniqueness. The study found that stretches of DNA with high variability in Drosophila simulans did not match up with areas of divergence between species.

12 fly genomes published

The complete genomes of 12 Drosophila species were published in Nature, revealing genetic differences similar to those between humans and chickens. This research provides a less-biased view of evolutionary processes, enabling a better understanding of the human genome.

Supplements even confuse athletes

A study found that athletes frequently take supplements without knowledge of their actual effects, leading to potential health risks. The research team recommends that education about supplement use become a required part of sport coach accreditation.

Key to false memories uncovered

Duke University neuroscientists discovered that the brain region processing global gist of an event is more active in individuals with false memories. This finding could lead to tools for early Alzheimer's disease diagnosis and a better understanding of memory changes during aging.

Hemoglobin uncovered

A team of researchers has made a breakthrough in understanding the mechanisms that regulate hemoglobin's ability to transport oxygen. By using sophisticated atomic calculation techniques, they have identified the factors that control hemoglobin's affinity for oxygen, which can now be used to design alterations of its structure.
