In wake of uproar over Facebook’s emotional manipulation study, bioethics scholars say new rules are ‘moral imperative’

In wake of uproar over Facebook’s emotional manipulation study, bioethics scholars say new rules are ‘moral imperative’

In a digital world where many adults remember a time before personal computers and the internet existed, its not surprising that ethics policies and practices are still catching up to the technology, acknowledge an international team of research ethics scholars in Proceedings of the National Academy of Sciences (PNAS).

Platelet-like particles augment natural blood clotting for treating trauma

Platelet-like particles augment natural blood clotting for treating trauma

A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries — and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets. The clotting particles, which are based on soft and deformable hydrogel materials, are triggered by the same factor that initiates the body’s own clotting processes Continue reading

Stigma as a barrier to mental health care

Stigma as a barrier to mental health care

Over 60 million Americans are thought to experience mental illness in a given year, and the impacts of mental illness are undoubtedly felt by millions more in the form of family members, friends, and coworkers. Despite the availability of effective evidence-based treatment, about 40% of individuals with serious mental illness do not receive care and many who begin an intervention fail to complete it. A new report, published in Psychological Science in the Public Interest , a journal of the Association for Psychological Science, investigates stigma as a significant barrier to care for many individuals with mental illness.

Banked blood grows stiffer with age, study finds

Banked blood grows stiffer with age, study finds

It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study from University of Illinois researchers. Using advanced optical techniques, the researchers measured the stiffness of the membrane surrounding red blood cells over time Continue reading

New way to diagnose malaria by detecting parasite’s waste in infected blood cells

New way to diagnose malaria by detecting parasite’s waste in infected blood cells

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye, and looks under a microscope for the Plasmodium parasite, which causes the disease.

C2D2 fighting corrosion

C2D2 fighting corrosion

Bridges become an infrastructure problem as they get older, as de-icing salt and carbon dioxide gradually destroy the reinforced concrete. A new robot can now check the condition of these structures, even in places that people cannot reach. We rely on Switzerland’s 3,500 motorway bridges — plus thousands more on cantonal roads — to carry us safely across valleys, streams, rivers and other roads Continue reading

Playing hunger games: Are gamified health apps putting odds in your favor?

Playing hunger games: Are gamified health apps putting odds in your favor?

For many people, finding motivation to exercise is a challenge. Thankfully, there are Zombies chasing you. At least that’s the approach of Zombies, Run! — one of more than 31,000 health and fitness apps on the market today, and one of the growing number of apps that use games to increase physical activity.

Space station inspired robot to help heal sick children

Space station inspired robot to help heal sick children

Children love robots. In all shapes, sizes, “personalities” and “smarts,” these electronic wonders have been found under Christmas trees by kids and unwrapped on birthdays for years. The gift of space-inspired robotics now goes beyond toys Continue reading

Novel gene predicts both breast cancer relapse, response to chemotherapy

Scientists have made it easier to predict both breast cancer relapses and responses to chemotherapy, through the identification of a unique gene. Continue reading

Focal blood-brain-barrier disruption with high-frequency pulsed electric fields

Focal blood-brain-barrier disruption with high-frequency pulsed electric fields

A team of researchers from the Virginia Tech-Wake Forest University School of Biomedical Engineering and Sciences have developed a new way of using electricity to open the blood-brain-barrier (BBB). Continue reading
