Stevens Institute of Technology, in partnership with the US Navy, has announced the debut of a unique research facility, the Secure Infrastructure Technology Laboratory (SINTEL).

New drug reverses effects of sleep deprivation on brain
Research in monkeys suggests that a new drug can temporarily improve performance and reverse the effects of sleep deprivation on the brain, which would be a breakthrough in helping shift workers, health professionals, military personnel and others who must function at top performance in spite of sleep deficits.

No evidence for variation in dementia incidence between areas with different vascular disease risk or between men and women, nor for reduced incidence amongst oldest age groups, according to a paper published in the open access journal PLoS Medicine.

Measuring hidden parasites in falciparum malaria
Measuring sequestered parasites using plasma PfHRP2 concentrations may provide a more accurate estimate of total parasite mass and hence severity in falciparum malaria, a paper published in the open access journal PLoS Medicine reveals.

Early clinical signs of ovarian cancer
Many women diagnosed with ovarian cancer actually complained of symptoms of the disease at least four months before they were diagnosed, according to a new study.

Researchers from Case Western Reserve University examined data from 12,110 individuals who participated in the third National Health and Nutrition Examination Survey (NHANES III) and found that individuals who exercised, had healthy eating habits and maintained a normal weight were 40 percent less likely to develop periodontitis, a gum infection that can result in loss of teeth.

Civilian helicopter crash-resistant fuel systems could be more effective
Researchers from the Johns Hopkins Bloomberg School of Public Health Center for Injury Research and Policy found that the crash-resistant standards for the fuel systems of civilian helicopters are not as effective in protecting passengers in survivable crashes as stricter military helicopter standards.

Reversal of role for a viral protein associated with the development of lymphoma
A protein thought to hinder the activity of a key cellular protein linked to cancer cell death now appears to mimic the signaling of that protein; potentially leading to the development of lymphoma.
