According to epigenetics -- the study of inheritable changes in gene expression not directly coded in our DNA -- our life experiences may be passed on to our children and our children's children. Studies on survivors of traumatic events have suggested that exposure to stress may indeed have lasting…

Researchers detected evidence of concussions in patients up to 7 days after their injury using a simple blood test -- which could greatly expand the window for diagnosing concussions, especially in patients who experience a delayed onset of symptoms.

The largest network to date of connections between neurons in the cortex, where high-level processing occurs, has been published. It has revealed several crucial elements of how networks in the brain are organized.

A mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) has been discovered and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.

Experts applaud Oregon's new birth control law, which allows women age 18 or older to obtain some methods of hormonal contraception directly from pharmacies, without having to visit a prescribing clinician, yet note how the law could go even further to improve access to all forms of contraception,…

To provide oncologists a way to detect a single molecule of an enzyme produced by circulating cancer cells, physicists and engineers have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available. The device proved…

Scientists have resurrected a discarded drug that helps human cells in a lab dish fight off two different viruses. Based on what they learned about how the drug works, it might also help fight the viruses that cause Ebola, dengue and Zika, among others, they say.

People with cancer have tumor DNA in their blood. A new way to quiet background 'noise' in the blood sample allows researchers to sequence minute quantities of these molecules to improve diagnosis and treatment.

Researchers have successfully directed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats, resulting in functional benefit, a new article reports.

Weight loss surgery was more effective than a low-fat diet at reversing the cancer-promoting effects of chronic obesity in mice.

Researchers examined whether weight loss via four different diets was linked to reduced tumor growth in laboratory models of breast cancer.

A new mathematical model shows how fertility goes down as the cost of achieving social status goes up. The study authors developed a mathematical model showing that their argument is plausible from a biological point of view.

Research finds that 'multimodal' communication -- using a mix of words, images and other resources - is important for students and faculty in higher education, a finding that argues for increased instruction in multimodal communication for undergraduates.

A new reason has been found for firms to price below cost and it's not to undercut the competition. Turns out exchange rates and currency fluctuations may actually cause a corporation to price below cost to ensure consistent profit margins across a global supply chain.

Gleevec, which is used in leukemia medications, holds promise for a dramatically more effective treatment of type 2 diabetes, report scientists.

A large study from Japan found that cancer patients who died at home tended to live longer than those who died in hospitals.

Majority of human Src homology 2 (SH2) domains not only bind to proteins, but also interact with membrane lipids with high affinity and specificity. The SH2 domain-containing proteins play important roles in various physiological processes and are involved in cancer development. This study reveals…

For those highly determined to pursue a profession, receiving negative feedback may lead to the endorsement of immoral behavior, a team of researchers has found.

Working with human breast cancer cells and mice, scientists say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer…

A discovery has been made on just how we know when to empty our bladders, which may have the potential to lead to new therapeutic interventions for bladder dysfunction.

Companies appear to structure compensation contracts and incentive pay based on a manager's personality traits, and not just firm characteristics, according to a new study.

Intracellular protein trafficking is important for higher brain functions such as learning and memory, new research has found. The research group showed that a molecule, ARHGAP33 regulates synaptic functions and behaviors via intracellular protein trafficking and that the lack of ARHGAP33 causes…

In what would be considered good news for many parents, a new study finds the rates of ear infections during a baby's first year have declined; the investigators suggested that higher rates of breastfeeding, use of vaccinations and lower rates of smoking may be the major contributors.

Combustible tobacco cigarettes cost less to purchase than equivalent amounts of electronic cigarettes (e-cigarettes) in 44 of 45 countries sampled around the world.

Researchers have identified a single, universal facial expression that is interpreted across many cultures as the embodiment of negative emotion. The look proved identical for native speakers of English, Spanish, Mandarin Chinese and American Sign Language. It consists of a furrowed brow, pressed…
