Enzyme that breaks down amino acids may promote aging

Kobe University

Permanently arrested cell growth is known as "cellular senescence", and the accumulation of senescent cells may be one cause of aging in our bodies. Japanese researchers have discovered that a certain enzyme in our bodies promotes cellular senescence by producing reactive oxygen species. Drugs that target this enzyme could potentially suppress this process, and inhibit aging and aging-related illnesses.

Body-Painting Protects Against Bloodsucking Insects

Lund University

A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne diseases.

Individual lichens can have up to three fungi, study shows

University of Alberta

EDMONTON (EMBARGOED UNTIL Thursday, January 17 at 11 a.m. EST)—Individual lichens may contain up to three different fungi, according to new research from an international team of researchers. This evidence provides new insight into another recent discovery that showed lichen are made up of more than a single fungus and alga, overturning the prevailing theory of more than 150 years.

Researchers Create ‘Shortcut’ to Terpene Biosynthesis in E. coli

North Carolina State University

Researchers from North Carolina State University have developed an artificial enzymatic pathway for synthesizing isoprenoids, or terpenes, in E.coli. This shorter, more efficient, cost-effective and customizable pathway transforms E. coli into a factory that can produce terpenes for use in everything from cancer drugs to biofuels.

Fever alters immune cells so they can better reach infections

Cell Press

Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to travel via blood vessels to reach the site of infection. Their work appears on January 15 in the journal Immunity.

Engineered T cells promote long-term organ transplant acceptance

University of Basel

Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening infections. Researchers at the University of Basel's Biozentrum have now discovered a molecular approach preventing rejection of the transplanted graft while simultaneously maintaining the ability to fight against infections.

The algae's third eye

University of Würzburg

Just like land plants, algae use sunlight as an energy source. Many green algae actively move in the water; they can approach the light or move away from it. For this they use special sensors (photoreceptors) with which they perceive light.

Viral production is not essential for deaths caused by food-borne pathogen

PLOS

The replication of a bacterial virus is not necessary to cause lethal disease in a mouse model of a food-borne pathogen called Enterohemorrhagic Escherichia coli (EHEC), according to a study published January 10 in the open-access journal PLOS Pathogens by Sowmya Balasubramanian, John Leong and Marcia Osburne of Tufts University School of Medicine, and colleagues. The surprising findings could lead to the development of novel strategies for the treatment of EHEC and life-threatening kidney-related complications in children.
