Researchers identify how Ebola virus dodges the body's antiviral defenses

Researchers at the Washington University School of Medicine have identified one way the Ebola virus dodges the body's antiviral defenses, providing important insight that could lead to new therapies, in research results published in the journal Cell Host & Microbe. [More]
Internal production of hydrogen peroxide can lead cells to exit cell cycle and become senescent

Internal production of hydrogen peroxide can lead cells to exit cell cycle and become senescent

What happens inside cells when they detect the activation of a cancer-inducing gene? Sometimes, cells are able to signal internally to stop the cell cycle. Such cells are able to enter, at least for a time, a protective non-growth state. [More]
Scientists identify developmental on-off switch for Streptomyces

Scientists identify developmental on-off switch for Streptomyces

Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines. [More]
Nasal septum cells can repair human articular cartilage defects

Nasal septum cells can repair human articular cartilage defects

Human articular cartilage defects can be treated with nasal septum cells. Researchers at the University and the University Hospital of Basel report that cells taken from the nasal septum are able to adapt to the environment of the knee joint and can thus repair articular cartilage defects. [More]

Special issue looks at how researchers use bioinformatics to understand plant form

As technology advances, science has become increasingly about data-how to gather it, organize it, and analyze it. [More]
Study compares FK506 and rapamycin for Schwann cell migration, peripheral nerve regeneration

Study compares FK506 and rapamycin for Schwann cell migration, peripheral nerve regeneration

FK506 possesses a well-studied neuroregenerative effect, stimulating neurite extension in the presence of nerve growth factor in vitro, and enhancing nerve regeneration following nerve crush injury and isografting. [More]
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 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

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]
