Hepatitis therapy: Kupffer cells adjust the balance between pathogen control and hepatocyte regenera

(Elsevier) Scientists from TWINCORE have now published new insights on the processes involved in liver inflammation in the Journal of Hepatology: Type I interferons, on the one hand, limit viral replication and thereby help the immune cells to control the viral pathogen. On the other hand, type I interferons delay the regeneration of immune cells, which are important to adjust and maintain the imm...

Timothy Ray Brown, cured of HIV, rallies public to support research funding

(Mary Ann Liebert, Inc./Genetic Engineering News) In the 10th anniversary year since a bone marrow stem cell transplant cured Timothy Ray Brown of his HIV infection, despite disappointment over decreasing public desire to find a cure for HIV, Timothy Ray Brown remains optimistic that the scientific and medical communities can and will achieve this if properly funded.

Mantis shrimp size each other up before ceding a fight

(Duke University) To a mantis shrimp, walking away from a fight doesn't mean being a wimp. It means recognizing who they're up against and knowing when to bail rather than drag out a doomed battle, Duke University researchers say. Mantis shrimp use sparring matches to decide when to fight and when to fold, finds a study published Jan. 17 in the journal Proceedings of the Royal Society B.

California sea lion population rebounded to new highs

(NOAA Fisheries West Coast Region) California sea lions have fully rebounded under the protection of the Marine Mammal Protection Act, with their population on the West Coast reaching carrying capacity in 2008 before unusually warm ocean conditions reduced their numbers, according to the first comprehensive population assessment of the species.

Coping with climate stress in Antarctica

(University of California - Davis) Some Antarctic fish living in the planet's coldest waters are able to cope with the stress of rising carbon dioxide levels the ocean. They can even tolerate slightly warmer waters. But they can't deal with both climate change stressors at the same time, according to a study from the University of California, Davis.

New research to help reduce number of algae blooms that form annually

Review examines the pros and cons of surgery to reduce the risk of cancer

(Wiley) Genetic testing is commonplace for many inheritable cancer syndromes, and with that comes the knowledge of being a gene carrier for some patients. Many guidelines recommend that gene carriers take certain steps, such as surgery, to reduce their risk of developing cancer. A new BJS (British Journal of Surgery) review explores the quality-of-life consequences of genetic testing and risk-redu...

New research could significantly accelerate drug discovery

(University of Maryland School of Medicine) Many drugs work by inhibiting protein enzymes associated with a particular disease. Unfortunately, the same drugs can inhibit protein enzymes unrelated to the disease, resulting in harmful side effects. Computational biologists have a way to identify the features that distinguish one enzyme from similar enzymes. This research has the potential to signifi...

Lessons in nature boost classroom engagement afterward, researchers report

(University of Illinois at Urbana-Champaign) Third-graders who spend a class session in a natural outdoor setting are more engaged and less distracted in their regular classroom afterward than when they remain indoors, scientists found in a new study.
