Scientists boost gene-editing tools to new heights in human stem cells

Scientists have developed a new TREE method (an acronym short for transient reporter for editing enrichment, or TREE), which allows for bulk enrichment of DNA base-edited cell populations -- and for the first time, high efficiency in human stem cell lines.

Modeling study estimates spread of 2019 novel coronavirus

New modeling research estimates that up to 75,800 individuals in the Chinese city of Wuhan may have been infected with 2019 novel coronavirus (2019-nCoV) as of Jan. 25, 2020. The authors caution that given the lack of a robust and detailed timeline of records of suspected, probable, and confirmed cases and close contacts, the true size of the epidemic and its pandemic potential remains unclear.

Watching bat coronaviruses with next-generation sequencing

On January 21, the first case of the Wuhan coronavirus, named 2019-nCoV, was diagnosed in the United States. The virus has killed at least 17 people in China and sickened hundreds, primarily in Asian countries. Coronaviruses (CoVs) in bats have been linked to that outbreak, as well as outbreaks of diseases like SARS and MERS. Next-generation sequencing may be used to monitor the virus and how it spreads. This study describes a targeted NGS approach that can increase sensitivity and reduce cost. Researchers say this approach can help them maintain a library of genetic material from emerging CoVs, and track the origin and evolution of CoVs that cause outbreaks.

Could resetting our internal clocks help control diabetes?

The circadian clock system allows the organisms to adjust to periodical changes of geophysical time. Today, increasing evidence show that disturbances in our internal clocks stemming from frequent time zone changes, irregular working schedules or ageing, have a significant impact on the development of metabolic diseases including type-2 diabetes. Using a molecule extracted from lemon peel, researchers have succeeded in 'repairing' the disrupted cellular clocks.

Deciphering the sugar code

Like animals and humans, plants possess a kind of immune system. It can e.g. recognize pathogenic fungi by the chitin in their cell walls, triggering disease resistance.

Researchers now found that plants can react to a certain pattern in this chitosan, stimulating their immune system.

To reverse engineer dynamics of microbial communities, researchers construct their own

Scientific and public appreciation for microbes -- and the key role their communal actions play in environmental health, food production, and human wellness -- has grown in recent years. While initially considered to be static, uniform entities, microbial communities are highly complex and contain internal chemical swapfests that are in constant flux. Researchers have demonstrated that the dynamics of these communities can be explained and even predicted by examining the variability trait of microbial social interactions.

Reducing the risk of blood clots in artificial heart valves

People with mechanical heart valves need blood thinners on a daily basis, because they have a higher risk of blood clots and stroke. Researchers now identified the root cause of blood turbulence leading to clotting. Design optimization could greatly reduce the risk of clotting and enable these patients to live without life-long medication.

Fewer than two in every 100 packed lunches eaten by children in English primary schools meet nutritional standards, according to a major survey. Although the amount of sugary food in lunchboxes declined over 10 years it is still higher than recommended, and there has been a drop in essential vitamins and minerals. Researchers say the lack of fresh food is to blame.

Biological clock is key to reducing heart damage from radiation therapy

A new study suggests that the biological clock is involved in heart toxicity from radiation therapy and could be harnessed as part of a preventive strategy. Findings show that after receiving radiation to the heart, mice with disrupted biological clocks had significantly worse heart function than controls. They also demonstrated that Bmal1 -- a protein that drives 24-hour rhythms in the expression of many genes -- plays an important role in protecting the heart from radiation-related damage.

Calculated surprise leads to groundbreaking discovery in cognitive control research

To better understand how motivational control processes help maximize performance when faced with task challenges, researchers used functional magnetic resonance imaging (fMRI) and provide fascinating insights into the role of the dorsal anterior cingulate cortex (dACC) as a component network of brain regions that support motivated behavior. They have unified conflicting findings by discovering that the single mechanism of surprise best accounts for activity in dACC during a task requiring motivated control.
