Researchers at Jefferson Medical College and at the Wadsworth Center in New York have identified a gene defect in mice resulting in a range of abnormalities, from cyclical hair loss and skin cancer to severe problems in normal skin development. The work may lead to improved treatments for skin injuries, including burns, and might have implications for diseases such as eczema and psoriasis, as well as certain cancers.
Linda Siracusa, Ph.D., associate professor of microbiology and immunology at Jefferson Medical College of Thomas Jefferson University in Philadelphia and at Jeffersons Kimmel Cancer Center and Bruce Herron, Ph.D., a research scientist at the Wadsworth Center of the New York State Department of Health and assistant professor in the Department of Biomedical Sciences at the State University of New York at Albany, wanted to identify the nature of an inherited genetic mutation in mice called repeated epilation (Er), and pinpoint the gene itself.
Mice carrying one copy of the mutation have cyclical hair loss, and develop skin cancer late in life. Mice carrying two copies have severe defects in skin development related to keratinocyte (skin cell) differentiation. At birth, they lack external openings – the nose and mouth are covered by skin, for example – and live only a brief time.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
