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.

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.

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.

Acute sense of touch helps hummingbirds hover near a flower without bumping into it      (via sciencedaily.com)     Original source 

Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.

Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis while sparing healthy microbes in the mouse gut. The drug, called lolamicin, also warded off secondary infections with Clostridioides difficile, a common and dangerous hospital-associated bacterial infection, and was effective against more than 130 multidrug-resistant bacterial strains in cell culture.
