Engineering viruses to kill deadly pathogens      (via sciencedaily.com)     Original source 

Antimicrobial resistance is an urgent and growing global crisis. Researchers are exploring phages, viruses that infect bacteria, as a possible solution. In the new study, researchers successfully modified DNA from four types of phages to kill a deadly pathogen. The process can also be used to produce more phage variants for further exploration.

Cosmic building blocks of life discovered through the electron microscope      (via sciencedaily.com)     Original source 

Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons -- without applying any chemical treatment and by using a new type of detector design.

How obesity dismantles our mitochondria      (via sciencedaily.com)     Original source 

Researchers found that when mice were fed a high-fat diet, mitochondria within their fat cells broke apart and were less able to burn fat, leading to weight gain. They also found they could reverse the effect by targeting a single gene, suggesting a new treatment strategy for obesity.

Researchers map genome for cats, dolphins, birds, and dozens of other animals      (via sciencedaily.com)     Original source 

Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.

Use it or lose it: How seagrasses conquered the sea      (via sciencedaily.com)     Original source 

Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.

How HIV smuggles its genetic material into the cell nucleus      (via sciencedaily.com)     Original source 

Around one million individuals worldwide become infected with HIV, the virus that causes AIDS, each year. To replicate and spread the infection, the virus must smuggle its genetic material into the cell nucleus and integrate it into a chromosome. Research teams have now discovered that its capsid has evolved into a molecular transporter. As such, it can directly breach a crucial barrier, which normally protects the cell nucleus against viral invaders. This way of smuggling keeps the viral genome invisible to anti-viral sensors in the cytoplasm.

How macrophages regulate regenerative healing in spiny mice      (via sciencedaily.com)     Original source 

A team of researchers is delving deeper into the science behind how spiny mice can regenerate lost tissue and using what they learn to trigger regeneration in other types of mice -- advances which one day may be translated into humans. Whereas adult laboratory mice heal injuries with scar tissue, spiny mice have the unique ability to regrow lost skin and regenerate musculoskeletal tissues in their body.
