Additive effect of small gene variations can increase risk of autism spectrum disorders

Researchers found that small genetic variations can accumulate and contribute to the risk of autism spectrum disorders. In families where only one child has ASD, 40% of the risk is inherited, rising to 60% in families with multiple affected children. These findings provide new insights into the genetic factors underlying ASD.

Where there is no paramedic

A collaboration developed and studied a community-based first response training program in a remote Indigenous community in northern Canada. The program, funded by the Canadian Institutes of Health Research and Northern Ontario Academic Medical Association, improved emergency care outcomes.

Misconduct, not error, accounts for most scientific paper retractions

A new study found that misconduct accounts for two-thirds of all retracted scientific papers, with fraud or suspected fraud being the leading cause. The number of retractions has increased 10-fold since 1975, attributed to a winner-take-all culture in science that rewards publication and reputation over integrity.

Autism Speaks awards nearly $5 million

Autism Speaks has awarded nearly $5 million in research grants to support various studies on autism, including the effects of pregnancy medications on future generations. These grants will fund projects that aim to identify biomarkers for response to autism medications, develop new interventions, and expand food choices for picky eater...

PLOS Medicine editors comment on progress of World Health Report 2012

The PLOS Medicine Editors report on the delays and changes in scope of the World Health Organization's (WHO) World Health Report 2012. The original report was planned for publication in 2012, but it has been delayed until 2013. The focus of the new report will be on universal health coverage, but its scope is still unclear.

Mount Sinai researchers awarded 'Provocative Questions' grant from National Cancer Institute

Researchers Stuart Aaronson and Ross Cagan received a $351,713 grant from the National Cancer Institute to investigate signaling pathways responsible for Wnt oncogene addiction. They aim to discover potent drugs that can disrupt this addiction in tumor cells, increasing the efficacy of therapy for Wnt-activated human cancers.

Statins are unlikely to prevent blood clots

A large analysis of over 100,000 participants found that statins have a very small effect on preventing venous thromboembolic events. The study suggests that high-dose and low-dose statins have no effect on blood clots.

Looking at you: Face genes identified

A study has identified five genes responsible for human facial morphology, with three previously implicated in vertebrate craniofacial development and disease. The remaining two genes are new players in the molecular networks governing facial development.

Predicting if scientists will be stars

A new Northwestern University study developed a formula that accurately predicts a young scientist's success in the life sciences, considering factors like publications, h-index, and high-impact journal articles. The formula is more than twice as accurate as existing methods for predicting future success.

Southeast Asian ovalocytosis protects against P. vivax malaria

A multinational group of authors has found a strong association between Southeast Asian ovalocytosis and protection against malaria caused by Plasmodium vivax. The study suggests that P. vivax malaria may have contributed to shaping the unique host genetic adaptations in Asian and Oceanic populations.
