Researchers identify histone proteins that may be key to generate induced totipotent stem cells

One major challenge in stem cell research has been to reprogram differentiated cells to a totipotent state. Researchers from RIKEN in Japan have identified a duo of histone proteins that dramatically enhance the generation of induced pluripotent stem cells (iPS cells) and may be the key to generating induced totipotent stem cells.

Researchers evaluate feasibility of using stem cell therapies on preterm infants to treat BPD

Advances in neonatal care for very preterm infants have greatly increased the chances of survival for these fragile infants. However, preterm infants have an increased risk of developing bronchopulmonary dysplasia (BPD), a serious lung disease, which is a major cause of death and lifelong complications.

New book encourages critical thinking and effective action for future of global agrifood system

Carbon dioxide emissions from transportation, energy generation and built infrastructure may be major contributors to climate change, but they may not be the biggest ones. According to UC Santa Barbara environmental science professor David A. Cleveland, that dubious distinction could go to the agrifood system.

Study: Rise of tuberculosis in Zimbabwe linked with widespread food shortage

The rise of tuberculosis (TB) in Zimbabwe during the socio-economic crisis of 2008-9 has been linked to widespread food shortage, according to a new study led by Canadian researchers from the University of Toronto Dalla Lana School of Public Health published in PLOS ONE.

Minimizing person's sight may help improve brain's ability to process hearing

Minimizing a person's sight for as little as a week may help improve the brain's ability to process hearing, neuroscientists have found.

Research examines differences between male and female brain that contributes to violent behavior

Human behaviors such as violence depend on interactions in the brain between genetic and environmental factors. An individual may be more vulnerable to developing violent behaviors if they have predisposing factors and are then exposed to stress, abuse, or other triggers, especially early in life.

Chinese scientists confirm world’s first case of human infection with new avian influenza virus

Scientists from China report in The Lancet on the world’s first confirmed case of human infection with a new avian influenza A H10N8 virus in a 73-year-old woman who died from the infection.

Scientists discover new mechanism governing brain stem cell proliferation

Higher mammals, such as humans, have markedly larger brains than other mammals. Scientists from the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden recently discovered a new mechanism governing brain stem cell proliferation.

Study provides evidence for importance of omega-3 fatty acids in healthy brain development

Monkeys that ate a diet rich in omega-3 fatty acids had brains with highly connected and well organized neural networks - in some ways akin to the neural networks in healthy humans - while monkeys that ate a diet deficient in the fatty acids had much more limited brain networking, according to an Oregon Health & Science University study.

Researchers make first link between menopause, smoking and genetic variations in white women

New research is lighting up yet another reason for women to quit smoking. In a study published online in the journal Menopause, researchers from the Perelman School of Medicine at the University of Pennsylvania report the first evidence showing that smoking causes earlier signs of menopause - in the case of heavy smokers, up to nine years earlier than average - in white women with certain genetic variations.

New effective method of treatment against increased cholesterol

Cardiovascular diseases are the number one cause of death globally due to e.g. arteriosclerosis. The cause is increased cholesterol. There is therefore a considerable need for an effective method of treatment against increased cholesterol. Now, Danish researchers have made a discovery that may change the picture of how it must be treated.

6-month-old infants later diagnosed with autism divert gaze from facial features

From birth, infants naturally show a preference for human contact and interaction, including faces and voices. These basic predispositions to social stimuli are altered in individuals diagnosed with autism spectrum disorders (ASD).

Researchers identify specific biomarkers of obesity and early-stage colon cancer

Obesity is a known risk factor for many cancers including colon cancer, yet the reasons behind the colon cancer link have often remained unclear.

Findings explain molecular mechanisms underlying microvascular disease in diabetes patients

Patients with diabetes are at increased risk of microvascular complications, which develop when the body's small blood vessels become diseased. One of the most common problems results when wounds fail to heal properly, which can lead to ulcers, chronic infections, and in the most serious cases, limb amputations.

New study correlates brain activity with how people make decisions when they engage in risky behavior

A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it's probably not because their brains' desire systems are too active, but because their self-control systems are not active enough.

NeuroRehabilitation showcases different approaches to restoring mental functioning

There is a growing need for Cognitive Rehabilitation Therapy (CRT) due to the huge influx of soldiers returning from war zones with brain injuries, athletes with sports-related head injuries, and the growing population with age-related cognitive decline.
