Researchers discover 'trojan horse' virus hiding in human parasite      (via sciencedaily.com)     Original source 

An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.

Lighting up the brain: What happens when our 'serotonin center' is triggered?      (via sciencedaily.com)     Original source 

Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, they found that serotonin from the DRN activates brain areas that affect behavior and motivation. Results show that DRN serotonin stimulation causes activation of the cerebral cortex and the basal ganglia, brain areas involved in many cognitive functions.

Mediterranean diet tied to one-fifth lower risk of early death in women      (via sciencedaily.com)     Original source 

In a new study that followed more than 25,000 initially healthy U.S. women for up to 25 years, researchers found that participants who had greater Mediterranean diet intake had up to 23% lower risk of all-cause mortality, with benefits for both cancer mortality and cardiovascular mortality.

People are altering decomposition rates in waterways      (via sciencedaily.com)     Original source 

Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.

New, modified CRISPR protein can fit inside virus used for gene therapy      (via sciencedaily.com)     Original source 

Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.

Historic iceberg surges offer insights on modern climate change      (via sciencedaily.com)     Original source 

A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.

Scientists invent 'living bioelectronics' that can sense and heal skin      (via sciencedaily.com)     Original source 

Reaserchers have created a prototype for what they call 'living bioelectronics': a combination of living cells, gel, and electronics that can integrate with living tissue. Tests in mice found that the devices could continuously monitor and improve psoriasis-like symptoms, without irritating skin.

Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years      (via sciencedaily.com)     Original source 

A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.

Indian Ocean surface temperature could help anticipate dengue outbreaks      (via sciencedaily.com)     Original source 

Although dengue outbreaks cannot be prevented, it is possible to anticipate them. Scientists have recently identified a global climate indicator that may help improve predictions about the magnitude of dengue outbreaks several months in advance. This indicator, which can be used for any world region, is based on temperature fluctuations at the surface of the Indian Ocean. Obtaining reliable long-term predictions could facilitate efforts to tackle this infection, which has been on the rise for several decades and threatens half of the world's population.

Researchers expose new symbiosis origin theories, identify experimental systems for plant life      (via sciencedaily.com)     Original source 

Research work on symbiosis -- a mutually beneficial relationship between living organisms -- is pushing back against the newer theory of a 'single-origin' of root nodule symbiosis (RNS) -- that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point--instead suggesting a 'multiple-origin' theory of sybiosis which opens a better understanding for genetically engineering crops.

A drying Salton Sea pollutes neighboring communities      (via sciencedaily.com)     Original source 

Dust particles from the Salton Sea's exposed lakebed increased air pollution in local communities, found a new study. The pollution coincides with reduced flows into the lake and diversions to San Diego.

Blood flow makes waves across the surface of the mouse brain      (via sciencedaily.com)     Original source 

Researchers have, for the first time, visualized the full network of blood vessels across the cortex of awake mice, finding that blood vessels rhythmically expand and contract leading to 'waves' washing across the surface of the brain. These findings improve the understanding of how the brain receives blood, though the function of the waves remains a mystery.

Editing without 'cutting': Molecular mechanisms of new gene-editing tool revealed      (via sciencedaily.com)     Original source 

New research has determined the spatial structure of various processes of a novel gene-editing tool called 'prime editor.' Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.
