Super high-resolution carbon estimates for endangered Madagascar

A team of researchers from Carnegie Institution, GoodPlanet Foundation, and World Wide Fund (WWF) has produced the first large-scale, high-resolution estimates of carbon stocks in remote and fragile Madagascar. The study found that humid mountain forests had the highest carbon densities, while deforestation reduced standing carbon stocks.

Finding it difficult to make a purchase? Try creating some distance from the problem

A new study published in the Journal of Consumer Research found that creating psychological distance can reduce cognitive difficulty and anxiety in choice situations. By manipulating abstract thinking and body postures, researchers discovered that leaning away from a screen or task can make decisions feel less difficult.

AGU: Journal Highlights Feb. 14 2012

Researchers found evidence supporting the single-water-source hypothesis for Yellowstone's geysers, suggesting a common source of subsurface water. Additionally, gravity waves in the Martian mesosphere were linked to the formation of carbon dioxide clouds, which could impact global climate models.

The indiscretions of a champagne bubble paparazzi

A study by Gérard Liger-Belair reveals the role of carbon dioxide in champagne bubbles, from second fermentation to gas escape through tiny bubbles popping on the surface of wine. The research provides clues for fine-tuning champagne production, including adjusting bubble size based on fermentation sugar levels.

Building bone from cartilage

Researchers at UCSF Orthopaedic Trauma Institute have found a promising method to regenerate bone using cartilage grafts, which can integrate with the host bone and vascularize it. This approach could offer an alternative to traditional bone grafting techniques, which can result in poor integration and osteonecrosis.

Mixed progress made by US government and schools to improve food marketing influencing children's diets

The US government and schools have made moderate progress in developing nutritional standards for foods sold in schools, but have failed to comprehensively address the issue of food marketing influencing children's diets. The Institute of Medicine recommended that public sector stakeholders support a healthful diet for children and ado...

Coral survival's past is key to its future

Researchers analyzed Caribbean coral extinctions during Plio-Pleistocene era and found strong relationships between past regional extinction events and modern coral vulnerability. The study suggests that extinction events depend on biological characteristics of the coral species, improving the accuracy of extinction-risk assessment.

Antibiotics ineffective for most sinus infections

According to investigators at Washington University School of Medicine, antibiotics do not reduce symptoms in sinus infection patients, with most people getting better on their own. The study suggests treating symptoms and watchful waiting may be more effective than antibiotic treatment.

Taking depression to heart

Researchers at Tel Aviv University found that depressed heart attack patients are more likely to be re-admitted for cardiac events and have longer hospital stays, with 14% more days of hospitalization compared to happier counterparts. The study suggests that investing in extra psychiatric support may have a large positive payoff.

Cost-effectiveness of HAART underestimated

The authors argue that HAART roll-out's cost-effectiveness has been significantly understated, as economic analyses fail to account for its role in preventing HIV transmission. This oversight highlights the need for expanded 'Seek, Test, Treat and Retain' programs to control HIV and AIDS-related morbidity, mortality, and transmission.

Fragmented sleep, fragmented mind: A new theory of sleep disruption and dissociation

A new theory suggests that sleep problems may contribute to dissociation and dissociative disorders. Research finds that sleep disturbances can impair memory and increase suggestibility, potentially increasing the impact of leading interventions. Therapists should adopt a more nuanced approach to treat patients with dissociative symptoms.

Weight loss can be contagious, study suggests

Researchers found that teammates and social influence play a significant role in weight loss, particularly in team-based weight loss competitions. Participants who said their teammates played a large role in their weight loss actually lost the most weight. Individual characteristics such as obesity status also affected weight outcomes.
