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.

Graphene gets cleaned up      (via sciencedaily.com)     Original source 

Engineers establish the link between oxygen and graphene quality and present an oxygen-free chemical vapor deposition method (OF-CVD) that can reproducibly create high-quality samples for large-scale production. The graphene they synthesized with their new method proved nearly identical to exfoliated samples and was capable of producing the fractional quantum Hall effect.

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.

New antibiotic kills pathogenic bacteria, spares healthy gut microbes      (via sciencedaily.com)     Original source 

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.

The case of the missing black holes      (via sciencedaily.com)     Original source 

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.

AI helps medical professionals read confusing EEGs to save lives      (via sciencedaily.com)     Original source 

Researchers have developed an assistive machine learning model that greatly improves the ability of medical professionals to read the electroencephalography (EEG) charts of intensive care patients. Because EEG readings are the only method for knowing when unconscious patients are in danger of suffering a seizure or are having seizure-like events, the computational tool could help save thousands of lives each year.

Electrochromic films -- like sunglasses for your windows?      (via sciencedaily.com)     Original source 

Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.

Chocolate's tasty flavors might pose a risk in other desserts      (via sciencedaily.com)     Original source 

What makes chocolate taste and smell so delicious? Chemistry, of course! A variety of molecules work together to create that unmistakable aroma, but those same molecules might carry some unwanted health effects if there are too many around. While many of the compounds appeared in chocolate in low enough concentrations to be safe, higher amounts were found in some baked sweet treats.

Risky path to meeting climate targets for Stockholm      (via sciencedaily.com)     Original source 

The Swedish capital Stockholm aims to capture more carbon dioxide than is emitted by 2030. Therefore, the city is investing in new technology at a combined heat and power plant. But it is a strategy that has been adopted without sufficient discussion of the risks.
