National Institute on Aging (NIA) researchers have discovered a new gene, FANCM, which sheds light on an important pathway involved in the repair of damaged DNA. Specifically, mutation in this gene is responsible for one of the forms of Fanconi anemia (FA), a rare genetic disorder that primarily affects children. Like many rare, inherited diseases, understanding this gene’s role in the development of FA provides insights into other medical problems -- in this case, age-related conditions including ovarian and pancreatic cancers, as well as leukemia, the researchers said. Discovery of this gene and its protein provides a potential target for the development of drugs that can prevent or alleviate FA and a variety of cancers.
The finding is scheduled for advanced online publication in Nature Genetics during the week of August 21, 2005.* The report also will be published in the journal’s September 2005 print edition. The NIA is a component of the National Institutes of Health (NIH) at the U.S. Department of Health and Human Services.
"FA is a disease that appears to be the result of a breakdown in vital DNA repair mechanisms," said Weidong Wang, Ph.D., a senior investigator in the NIA’s Laboratory of Genetics, who led the study. "Some scientists theorize that DNA damage, which gradually accumulates as we age, leads to malfunctioning genes and deteriorating tissues and organs as well as increased risk of cancer. We believe that this new gene, FANCM, may be a potent cog in the DNA repair machinery," Wang said. "It is possible that we could learn how to promote the function of DNA repair complexes and thereby prevent the age-related accumulation of DNA damage."

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
