Omega-3 fatty acids improve cognitive flexibility in older adults at risk of late-onset Alzheimer's disease

A study of older adults at risk of late-onset Alzheimer's disease found that those who consumed more omega-3 fatty acids did better than their peers on tests of cognitive flexibility -- the ability to efficiently switch between tasks -- and had a bigger anterior cingulate cortex, a brain region known to contribute to cognitive flexibility.

Nerve cells guide each other during embryonic development

When nerve cells form in an embryo they do not start off in the right place but have to be guided to their final position by navigating a kind of molecular and cellular "map" in order to function properly. In a recent research study published in Nature Communications neurobiologist Sara Wilson, Umeå University, found that during embryonic development different parts of the nerve cell are important for guiding other nerve cells into their physical positions.

Johns Hopkins researchers identify new therapy to treat lung cancer

A multidisciplinary team led by Johns Hopkins researcher Venu Raman, Ph.D., with notable contributions from Guus Bol, Farhad Vesuna and Phuoc Tran of Johns Hopkins, has identified a new therapy for lung cancer, the most common cancer worldwide. The therapy has been in development for six years and involves a first-in-class molecule designed by the team.

New research points to potential therapeutic target for treating multiple sclerosis

New research into the causes of the excessive inflammation that drives multiple sclerosis has identified a faulty "brake" within immune cells, a brake that should be controlling the inflammation. This points to a potential target for developing new therapies to treat multiple sclerosis and could have important implications for other autoimmune diseases, such as the colon disease colitis and the chronic skin condition atopic dermatitis.

University of Missouri researchers identify key protein component that causes cystic fibrosis

Nearly 70,000 people worldwide are living with cystic fibrosis, a life-threatening genetic disease. There currently is no cure for the condition, but researchers from the University of Missouri have identified a key component in the protein that causes the disease. It is a finding that may lay the foundation for the development of new medications and improved therapies.

Study: Air pollution, impaired lung function independently affect cognition

Studies have shown that both air pollution and impaired lung function can cause cognitive deficits, but it was unclear whether air pollution diminishes cognition by reducing breathing ability first or whether air pollution represents an independent risk factor for cognitive deficit.

New microfluidic chip can capture rare clusters of circulating tumor cells

Researchers have developed a microfluidic chip that can capture rare clusters of circulating tumor cells, which could yield important new insights into how cancer spreads. The work was funded by the National Institute of Biomedical Imaging and Bioengineering, part of the National Institutes of Health.

UC Irvine study shows youthful vigor can be restored to adult brains

They say you can't teach an old dog new tricks. The same can be said of the adult brain. Its connections are hard to change, while in children, novel experiences rapidly mold new connections during critical periods of brain development.

Researchers reveal molecular steps that allow pancreatic cancer to spread to the liver

An international team led by Weill Cornell Medical College investigators has illuminated the precise molecular steps that enable pancreatic cancer to spread to the liver -- the event that makes the most common form of the disease lethal. By understanding this process, investigators say their discovery can lead to targeted treatments that delay metastasis, and could offer clinicians a new biomarker to test for the earliest signs of pancreatic cancer.
