Researchers reveal how distinct areas of frontal lobes are critical for person's ability to learn

Researchers reveal how distinct areas of frontal lobes are critical for person's ability to learn

Until the last few decades, the frontal lobes of the brain were shrouded in mystery and erroneously thought of as nonessential for normal function-hence the frequent use of lobotomies in the early 20th century to treat psychiatric disorders. [More]

Surgical researchers rarely use female animals in medical research

A new study from Northwestern Medicine- has found that surgical researchers rarely use female animals or female cells in their published studies -- despite a huge body of evidence showing that sex differences can play a crucial role in medical research. [More]

Dartmouth researchers evaluate role of assortativity signature on robustness

Dartmouth researchers explored the type and number of connections in transcription factor networks (TFNs) to evaluate the role assortativity plays on robustness in a study published in PLOS Computational Biology in August. [More]
Blend of three monoclonal antibodies can protect monkeys against Ebola virus, says UTMB researcher

Blend of three monoclonal antibodies can protect monkeys against Ebola virus, says UTMB researcher

A leading U.S. Ebola researcher from the University of Texas Medical Branch at Galveston has gone on record stating that a blend of three monoclonal antibodies can completely protect monkeys against a lethal dose of Ebola virus up to 5 days after infection, at a time when the disease is severe.

Preventing tentacle-like structures from forming can stop spread of cancer entirely

Preventing tentacle-like structures from forming can stop spread of cancer entirely

A new study from the research group of Dr. John Lewis at the University of Alberta (Edmonton, AB) and the Lawson Health Research Institute (London, ON) has confirmed that "invadopodia" play a key role in the spread of cancer. The study, published in Cell Reports, shows preventing these tentacle-like structures from forming can stop the spread of cancer entirely. [More]

Factor in cells of naked mole rats protects activity of proteasome

Scientists at the Barshop Institute for Longevity and Aging Studies, part of the School of Medicine at the UT Health Science Center at San Antonio, have found another secret of longevity in the tissues of the longest-lived rodent, the naked mole rat. [More]
Gene therapy may offer significant advantages in prevention of botulism exposure

Gene therapy may offer significant advantages in prevention of botulism exposure

The current method to treat acute toxin poisoning is to inject antibodies, commonly produced in animals, to neutralize the toxin. But this method has challenges ranging from safety to difficulties in developing, producing and maintaining the anti-serums in large quantities. [More]
Researchers make surprising discoveries about the body's early responses to HIV infection

Researchers make surprising discoveries about the body's early responses to HIV infection

Researchers at UC Davis have made some surprising discoveries about the body's initial responses to HIV infection. Studying simian immunodeficiency virus (SIV), the team found that specialized cells in the intestine called Paneth cells are early responders to viral invasion and are the source of gut inflammation by producing a cytokine called interleukin-1 beta (IL-1β).

Alternatives to cigarette smoking may still pose a risk to human health due to over-use

Alternatives to cigarette smoking may still pose a risk to human health due to over-use

Cigarette smoking kills approximately 440,000 Americans each year, according to the Centers for Disease Control and Protection. It's the leading cause of preventable death worldwide. In order to overcome this addiction, many people resort to nicotine replacement therapies. [More]

New adhesive method for repairing sciatic nerves

New adhesive method for repairing sciatic nerves

When repairing nerves with adhesives, most researchers place glue directly on the nerve stumps, but this method does not fix the nerve ends well and allows glue to easily invade the nerve ends. [More]

New online analytic tool enhances process of re-engineering cells for biomedical research

A Mayo Clinic researcher and his collaborators have developed an online analytic tool that will speed up and enhance the process of re-engineering cells for biomedical investigation. CellNet is a free-use Internet platform that uses network biology methods to aid stem cell engineering. [More]
CTC clusters cause metastasis

CTC clusters cause metastasis

Circulating tumor cell (CTC) clusters - clumps of from 2 to 50 tumor cells that break off a primary tumor and are carried through the bloodstream - appear to be much more likely to cause metastasis than are single CTCs, according to a study from investigators at the Massachusetts General Hospital Cancer Center.
