What can be done to prevent another CRISPR crisis?

A new article recommends explicit management of conflict of interests, banning exclusive rights to research results, and enhanced informed consent to guide germline gene editing. The author argues that regulation and penalties are necessary to ensure public trust in science.

Increased screen time in preschool is linked to inattention

Children with more than two hours of screen time per day were five times more likely to report clinically significant externalizing problems and had a significantly increased risk of attention-deficit/hyperactivity disorder. In contrast, children who engaged in organized sports showed fewer behavioral problems.

Oxytocin could help treat alcohol use disorder

A study published in PLOS Biology found that oxytocin administration can block excess drinking in alcohol-dependent rats, suggesting a potential novel pharmaceutical intervention for treating alcohol-use disorder. Oxytocin also blocked altered GABA signaling in the brain region affected by alcohol dependence.

Case of tick-borne relapsing fever in Mexico

A case of tick-borne relapsing fever was reported in Sonora, Mexico, where the disease gets little attention. The patient's symptoms improved with doxycycline treatment, and spirochetes were detected in her blood, supporting the identification of an endemic focus for the disease.

Bacteria flip an electric switch to worsen food poisoning

A new study reveals how Salmonella bacteria flip an electric switch within immune cells, causing them to migrate out of the gut and into the bloodstream. This mechanism contributes to the severity of food-borne illnesses, with over 400,000 deaths worldwide each year.

Disposable parts of plants mutate more quickly

A new study published in PLOS Biology found that plant parts with longer lifespans, such as stems and roots, have lower mutation rates compared to those with shorter lifespans, like leaves and petals. The researchers also discovered that plants with more future prospects for mutations tend to have lower relative mutation rates.

Sunscreen application has better face coverage than SPF moisturizers

A study published in PLOS ONE found that SPF moisturizer users incompletely cover their eyelid regions during application. The researchers compared sunscreen and moisturizer application and found significantly better coverage with sunscreen. This highlights the importance of using sunscreen for optimal sun protection.

Modelled climate change impact on mosquito-borne virus transmission

A study predicts climate change will lead to increased and new exposures to humans of diseases carried by mosquito vectors, with poleward shifts in Aedes-borne virus distributions. The model suggests a middle-of-the-road temperature increase could produce the greatest expansion in viral transmission by Ae. albopictus.

Two-step path to shrinking worker bee gonads

Researchers used CRISPR/Cas9 to selectively shut off a gene for female development, finding that diet has no effect on gonad size when the gene is turned off. This suggests that a specific genetic program must be switched on to permit nutrient level to affect gonad size.

New short-tailed whip scorpion species discovered in Amazon

A new species of Surazomus, a rare arachnid found in the Amazon, has been discovered with unique characteristics that provide insight into its mating habits. The species' male flagellum and female chelicerae anchor onto each other during copulation, offering clues about evolutionary changes within the genus.

North Africans were among the first to colonize the Canary Islands

A new study published in PLOS ONE found that people from North Africa were among the first to colonize the Canary Islands, arriving by 1000 CE. The researchers analyzed ancient mitochondrial genomes and identified lineages consistent with radiocarbon dating evidence, suggesting a complex and heterogeneous process of colonization.

Vaccine study confirms sensitivity of cholera test

A recent study using a cholera vaccine cluster trial found that conventional fecal microbiological cultures identified only 66% of patients with cholera, suggesting widespread underestimation of global cases. The study supported the sensitivity of these culture methods, but no evidence of protection was found.

Protected areas could help large herbivores bounce back after war

A new study reveals that protected areas can help large herbivores rapidly recover from war-induced declines. The study found that total biomass has substantially recovered since 1994, but species composition has shifted dramatically, with formerly dominant herbivores now outnumbered by smaller antelopes.
