Cry me a river: The psychology of crying

Researchers found that most respondents reported improved mood after a good cry, but some felt worse or no improvement. Criers who received social support experienced the most significant improvements in mood. The study highlights the complexities of crying behavior and its physical and emotional effects.

Collaboration of soloists makes the best science

A balance between large research groups and individual scientists is optimal for success, according to a novel theory by Adrian Bejan. Successful research groups grow naturally and contribute to the whole, while solitary thinkers have flourished throughout history due to science being good for society.

NRL scientists study cracks in brittle materials

Researchers used computer modeling and experimentation to investigate how cracks grow at low speeds in silicon, finding rearrangements of atoms associated with ductile materials can occur near the crack tip. This instability can lead to macroscopic changes in the path of the crack, leaving behind ridges on the crack surface.

NIH awards Rutgers Cell and DNA Repository $57.8M

The Rutgers University Cell and DNA Repository has received two major NIH awards to support investigations into the genetics of mental disorders, metabolic diseases, and digestive health. The funds will enable researchers to study the genetic causes of complex diseases such as autism, bipolar disorder, and diabetes.

Why current publication practices may distort science

A team of researchers argues that current publication practices create an extreme imbalance between the abundance of supply and limited venues for publication, leading to unrepresentative results. This distortion affects the broader scientific community, as only a small proportion of research findings are selected for publication.

Dark chocolate: Half a bar per week to keep at bay the risk of heart attack

A new study published in the Journal of Nutrition has found that consuming moderate amounts of dark chocolate (6.7 grams per day) can lower the risk of heart attack by significantly reducing inflammation and cardiovascular disease. The study, which enrolled over 20,000 participants, suggests that this amount of dark chocolate is associ...

Exercise in a pill

Researchers at the Salk Institute have identified two signaling pathways activated in response to exercise that converge to increase endurance. They discovered a drug, GW1516, that simultaneously triggers both pathways, turning laboratory mice into long-distance runners and conferring many exercise benefits.

AGU Journal Highlights -- June 11, 2008

A study finds that east Siberia's permafrost contains 500 Gt of frozen carbon deposits susceptible to disturbances from climate warming. The permafrost's irreversible thawing could release 2-2.8 Gt of carbon into the atmosphere annually between 2300 and 2400, transforming 74% of the initial carbon stock.

New target for Alzheimer's disease identified

Researchers at Gladstone Institutes have found that modulating enkephalin peptides in the brain may reduce cognitive deficits seen in Alzheimer's disease. Increased levels of preproenkephalin mRNA and enkephalins in brain regions affected by AD were observed, suggesting a potential new therapy target.

First steps toward autonomous robot surgeries

Researchers at Duke University have made significant advancements in autonomous robot surgeries, demonstrating the feasibility of robots performing complex procedures under real-time 3-D ultrasound guidance. The technology has the potential to improve patient safety by reducing radiation exposure and enhancing surgeon precision.

Too many choices -- good or bad -- can be mentally exhausting

A study by researchers from the American Psychological Association found that people experience mental fatigue and decreased productivity when faced with numerous choices. In experiments involving 328 participants, those who made choices had trouble staying focused and completing tasks compared to those who didn't make decisions.
