ILC 2017: New EASL clinical practice guidelines on the management of hepatitis B virus

The updated EASL guidelines provide new definitions of disease phases to guide clinicians on treatment indications. The guidelines also expanded indications for initiating treatment to prevent mother-to-child transmission and offer clear cut recommendations for special patient populations. The main goal of therapy is to improve surviva...

Building a better battery

A University of Houston graduate student has been awarded a NASA fellowship to identify new materials for next-generation batteries. He plans to use a combined computational and experimental approach to investigate solid-state electrolyte materials for lithium batteries.

Science is core to saving wildlife

The Wildlife Conservation Society emphasizes the importance of science in wildlife conservation, citing numerous examples including the prevention of American Bison extinction and forest elephant population recovery. Science informs their work through research papers, protected areas establishment, and policy development.

Keeping tabs on tau to track neurodegenerative disorder progression

Researchers have discovered an antibody that can detect tau in the serum of patients with tauopathies, a neurodegenerative disorder characterized by toxic protein clumps. The antibody, HJ8.5, has shown promise in increasing tau levels in human patients and mouse models, potentially paving the way for new treatments.

Ben-Gurion U. researchers develop membranes that remove viruses from drinking water

Ben-Gurion University researchers have developed novel ultrafiltration membranes that significantly improve virus-removal from treated municipal wastewater used for drinking. The new approach uses a special hydrogel coating to repel viruses, leading to a higher rate of removal and improved public safety in water-scarce cities.

Amino acids in diet could be key to starving cancer

Researchers found that removing serine and glycine from the diet of mice slowed lymphoma and intestinal cancer development. The special diet also made some cancer cells more susceptible to reactive oxygen species, which could boost conventional treatments' effectiveness. Next steps include clinical trials with cancer patients.

Identical twins; not-so-identical stem cells

Researchers found that even though iPSCs derived from identical twins have the same genes, they have distinct epigenetic markers, particularly near MYC binding sites. This discovery helps scientists better understand the processes involved in reprogramming cells and the differences between iPSCs and ESCs.

The foundations of parenting

Researchers found that different genes influence behaviors in males and females, and the gene for vasopressin is closely tied to nest-building behavior in mice. The study challenges the idea that experience drives parenting behavior and suggests that genetics play a significant role.

Fish cooperate for selfish reasons

African cichlid fishes evolved cooperative societies primarily due to fear of predators, which reduced their chances of being eaten. This alternative path to cooperation differs from other vertebrates, where relatedness is a key factor.

Moisture played a role in megafaunal extinctions

A recent study published in Nature Ecology and Evolution reveals that rising moisture levels may have contributed to the extinction of giant herbivores approximately 10,000 years ago. Researchers analyzed carbon and nitrogen isotopes in ancient animal bones to infer climate conditions and dietary habits of the megafauna.

A better life in the outback

New research suggests that Australia's desert region has huge potential for growth and development, particularly with investments in renewable energy, housing, and transport. The team aims to create a more livable and prosperous area for existing and new residents, in concert with the preferred lifestyles of Aboriginal peoples.
