Hydrologists diving off the coast of the Philippines have discovered volcanic seeps with some of the highest natural levels of C02 ever recorded. The scientists were working in Verde Island Passage, one of the most diverse marine ecosystems in the world and is home to thriving coral reefs.

Scientists identify gene that puts brakes on tissue growth

Added: 23.01.2020 0:20 | 17 views | 0 comments

The planarian flatworm is a simple animal with a mighty ability: it can regenerate itself from nearly every imaginable injury, including decapitation. Scientists have studied these worms for decades to better understand fundamental principles of natural regeneration and repair. One mechanism that is yet unknown is how organisms like these control the proportional scaling of tissue during regeneration. Now, molecular biologists have identified the beginnings of a genetic signaling pathway that puts the brakes on the animal's tissue growth.

Scientists have uncovered a broad diversity of large and giant viruses that belong to the nucleocytoplasmic large DNA viruses (NCLDV) supergroup. As a result, virus diversity in this group expanded 10-fold from just 205 genomes, redefining the phylogenetic tree of giant viruses.

Solving a biological puzzle: How stress causes gray hair

Added: 22.01.2020 22:20 | 11 views | 0 comments

Scientists have found evidence to support long-standing anecdotes that stress causes hair graying. Researchers found that in mice, the type of nerve involved in the fight-or-flight response causes permanent damage to the pigment-regenerating stem cells in the hair follicle. The findings advance knowledge of how stress impacts the body, and are a first step toward blocking its negative effects.

Researchers reverse HIV latency, important scientific step toward cure

Added: 22.01.2020 22:20 | 11 views | 0 comments

Overcoming HIV latency -- induction of HIV in CD4+ T cells that lay dormant throughout the body - is a major step toward creating a cure for HIV. For the first time, scientists have shown that a new approach can expose latent HIV to attack in two different animal model systems with little or no toxicity.

Mixing the unmixable: Novel approach for efficiently fusing different polymers

Added: 22.01.2020 22:20 | 18 views | 0 comments

Cross-linked polymers are structures where large molecular chains are linked together, allowing exceptional mechanical properties and chemical resistance to the final product. However, their modification is not easy. Now, scientists develop a method that allows the fusion of different polymers together easily, allowing the precise tuning of the properties of the final material by selecting appropriate base polymers and mixing them at the right proportion.
