Virus-like nanoparticles control the multicellular organization and reproduction of host bacteria      (via sciencedaily.com)     Original source 

Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.

Scientists unlock secrets of how archaea, the third domain of life, makes energy      (via sciencedaily.com)     Original source 

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.

Early life exposure to weed pollen could increase childhood asthma risk      (via sciencedaily.com)     Original source 

A study has found children who are exposed to tree and weed pollen in urban environments are at increased risk of respiratory health problems, including asthma. While green areas in urban settings decrease exposure to air pollution, allow kids to be active, and offer positive contact to a diverse microbiota -- which in turn may help the positive development of a child's immune system -- they can also lead to the development of childhood asthma. Thankfully, trees can help mitigate this effect to some degree, thanks to their canopy.

How human derived RNA fragments help the Hepatitis E virus      (via sciencedaily.com)     Original source 

Why does Hepatitis E become chronic in some patients, and why do medications not work? To find out, an international research team led by scientists from Bochum observed a patient with chronic Hepatitis E infection over a year. Repeated sequencing of the virus RNA showed that the virus incorporated various parts of the host's messenger RNA into its genome. This resulted in a replication advantage, which may have contributed to the infection becoming chronic.

Novel Genetic Clock discovers oldest known marine plant      (via sciencedaily.com)     Original source 

An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.

A protein that enables smell--and stops cell death      (via sciencedaily.com)     Original source 

While smell plays a considerable role in the social interactions of humans -- for instance, signaling fear or generating closeness -- for ants, it is vitally important. Researchers have found that a key protein named Orco, essential for the function of olfactory cells, is also critical for the cells' survival in ants.

Changes Upstream: RIPE team uses CRISPR/Cas9 to alter photosynthesis for the first time      (via sciencedaily.com)     Original source 

Scientists used CRISPR/Cas9 to increase gene expression in rice by changing its upstream regulatory DNA. While other studies have used the technology to knock out or decrease the expression of genes, this study, is an unbiased gene-editing approach to increase gene expression and downstream photosynthetic activity. The approach is more difficult than transgenic breeding, but could potentially preempt regulatory issues by changing DNA already within the plant, allowing the plants to get in the hands of farmers sooner.

Basic income can double global GDP while reducing carbon emissions      (via sciencedaily.com)     Original source 

Giving a regular cash payment to the entire world population has the potential to increase global gross domestic product (GDP) by 130%, according to a new analysis. Researchers suggest that charging carbon emitters with an emission tax could help fund such basic income program while reducing environmental degradation.
