First week after birth is critical for development of senses      (via sciencedaily.com)     Original source 

Researchers have found that the maturation of the senses for smell and touch is closely linked in mice and that this strong interaction takes place within a narrow developmental time window. These findings not only underline the importance of environmental stimuli for brain assembly in early life, but also the interdependent development of the senses.

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.

Lung organoids unveil secret: How pathogens infect human lung tissue      (via sciencedaily.com)     Original source 

How do pathogens invade the lungs? Using human lung microtissues, a team has uncovered the strategy used by a dangerous pathogen. The bacterium targets specific lung cells and has developed a sophisticated strategy to break through the lungs' line of defense.

Gut microbes from aged mice induce inflammation in young mice, study finds      (via sciencedaily.com)     Original source 

When scientists transplanted the gut microbes of aged mice into young 'germ-free' mice -- raised to have no gut microbes of their own -- the recipient mice experienced an increase in inflammation that parallels inflammatory processes associated with aging in humans. Young germ-free mice transplanted with microbes from other young mice had no such increase.

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.

Bartonella DNA Found in Blood of Patients With Psychosis      (via sciencedaily.com)     Original source 

A new study has found that patients diagnosed with schizophrenia or another psychotic disorder are three times more likely to have Bartonella DNA in their blood than adults without these disorders. The work further supports the idea that pathogens -- particularly vector-borne pathogens -- could play a role in mental illness.

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.
