The double life of a bacteria

Researchers discovered a bacterium that can use direct uptake of electrons from an electrode to fuel its metabolic pathway. This finding suggests the existence of electro-ecosystems, where microorganisms sustain life by electrical current, not relying on inorganic substances or light.

ESMO Asia 2015 Congress

The ESMO Asia 2015 Congress brought together cancer experts to discuss the latest treatment solutions and patient care. Researchers presented promising findings on immunotherapy and targeted therapy for difficult-to-treat head-and-neck cancers, as well as combination therapies for endocrine-resistant breast cancer.

Poverty may increase childhood risk of neurological impairment, NIH study suggests

Researchers found that children from low-income environments are at a higher risk of neurological impairment than those from more economically secure circumstances. The study suggests that maternal stress hormones during pregnancy and maltreatment may contribute to this increased risk.

Scientists find new vessel for detecting autism

Researchers at New York University found that individuals with autism have unstable blood vessels, disrupting brain function and circulation. The study identified a correlation between angiogenesis and neurogenesis, potentially leading to novel therapeutic interventions.

When trees die, water slows

A recent study found that widespread tree mortality from mountain pine beetles can reduce water availability due to increased evaporation, rather than increasing streamflow. This challenges previous assumptions and offers new insights for managing healthier forests that are more resistant to drought.

Lifespan -- genetic background and physical activity

A new study investigates the relationships between genetic background, physical activity level, and lifespan. The findings reveal that same genetic factors affect physical activity level, aerobic capacity, and lifespan in both animal models and human twins. Voluntary running improved glucose metabolism but did not increase lifespan in ...

Men actually recommend getting help for depression

A national survey found that men rank getting help from friends and family as highly important for addressing depression symptoms, with a score of 7.7 on an importance scale. In contrast, women prefer professional counseling more highly. Experts emphasize the need to overcome barriers and promote trustworthy mental health resources.

Scary movies can curdle blood

A small study found that watching horror movies significantly increased blood coagulant factor VIII levels in young and healthy adults, suggesting a physiological response to fear. The researchers argue that this increase is an evolutionary adaptation to prepare the body for blood loss during life-threatening situations.

Activating beige fat in humans could combat obesity

Researchers found that increasing energy expenditure with brown or brite/beige fat cells could be an effective way to fight obesity. The study suggests harnessing the body's natural mechanism of converting white fat cells into beige fat cells by using heat production and increasing the sympathetic nervous system's supply of blood vessels.

Naughty or nice? Is the way we 'perform' Santa Claus under threat?

A recent study published in Human Relations found that Santa Claus performers experience unease and threat due to the cultural re-association of the character with exploitative male sexuality. To address this, performers engage in self-management techniques, including having female staff present, to maintain the character's innocence.

Growing diversity in doctoral programs

A new coaching program at Northwestern University is boosting the persistence of underrepresented minority and female Ph.D. students towards academic careers. The program, which includes guidance from diverse coaches and peers, has shown positive results in increasing confidence and reducing feelings of pressure and isolation.

Toward roads that de-ice themselves

Researchers have developed a road material that de-ices itself by releasing de-icing salt as it wears away, potentially eliminating the need for annual salt applications. The new composite, combining potassium formate with styrene-butadiene-styrene and bitumen, significantly delays ice formation in lab studies.

Enemy odors help flies protect their offspring

Female Drosophila flies avoid laying eggs near parasitic wasps due to an innate early warning system that detects their odor. The study identified the specific olfactory circuit responsible for this detection, revealing a highly specific and efficient defense mechanism against predators.

UTA examines motivations behind adult learners' engineering degree pursuit

A new study from UTA explores the motivations behind adult learners' decision to pursue an engineering degree. Adult learners aged 25 and older are driven by perceived prestige and high career goals, including graduate school or internships. The study offers recommendations for campus policies and practices to support these students.
