Crustacean Research Reveals Malleable Genetic System for Circadian and Circatidal Rhythms

Crustacean Research Reveals Malleable Genetic System for Circadian and Circatidal Rhythms

Scientists at UMass Chan Medical School and the Marine Biological Laboratory at Woods Hole have discovered that the four core clock genes responsible for maintaining circadian rhythms in animals—Per, Cry2, Bmal1, and Clk—also regulate circatidal behavior in the crustacean *Parhyale hawaiensis*. While these genes are shared, their transcriptional wiring, or how they interact, differs between circadian and circatidal clocks. This allows the shrimp-like creatures to maintain both a 24-hour internal clock synchronized with light and dark cycles and a 12.4-hour clock synchronized with the tides. Specifically, Victoria Louis, PhD, a postdoctoral researcher in Emery's lab, found that in circatidal neurons, CLK represses the expression of Per independently of BMAL1, a deviation from its typical role in circadian neurons. This indicates distinct transcription factors control Per expression in circatidal versus circadian neurons. These findings, published in *Current Biology*, suggest a highly adaptable genetic syst...

NYU Langone Health Study Links GLP-1 Drugs to Increased Hair Loss Risk in Genetically Predisposed Men

NYU Langone Health Study Links GLP-1 Drugs to Increased Hair Loss Risk in Genetically Predisposed Men

A new study led by researchers at NYU Langone Health indicates that men with a genetic predisposition for androgenetic alopecia, the most common form of hair loss, face an additional 7% risk of hair loss when using GLP-1 medications such as Ozempic, Wegovy, and Zepbound. These drugs are prescribed for type 2 diabetes and obesity. The study, published online on September 3 in the Journal of Investigative Dermatology, focused on the GLP1R gene, which is associated with increased levels of glucagon-like peptide-1 (GLP-1) receptor proteins. Researchers compared the presence of GLP1R genes with genes found in men with androgenetic alopecia, an inherited pattern baldness. While rapid weight loss has previously been cited as a cause for hair thinning among GLP-1 users, this study provides the first genetic link, suggesting a biological connection. The analysis accounted for other known risk factors for hair loss, including hypertension, insulin resistance, and lowered testosterone levels, yet the 7% increased ris...

Waggles Pet Resort Owner Charged After Dog Dies in Scorching Van

Waggles Pet Resort Owner Charged After Dog Dies in Scorching Van

Ross Niehaus, the owner of Waggles Pet Resort in Wheeling, Illinois, has been charged with one count of cruel treatment of animals after a 6-year-old black lab named Miller died in his company's transport van. Miller was left in the van for approximately seven hours on a day when temperatures reached into the 90s with triple-digit heat indices. Steve Serota, Miller's owner, stated that the dog was a regular client of Waggles' chauffeur service, which advertises temperature-controlled transport. Serota expressed profound heartbreak and confusion over how his 110-pound dog, positioned in the first crate, could have been overlooked for such an extended period. The incident has prompted Serota to advocate for immediate safeguards to prevent similar tragedies.

New Study Links Over 1,200 Genetic Variants to Personality Traits and Life Outcomes

New Study Links Over 1,200 Genetic Variants to Personality Traits and Life Outcomes

An international consortium of researchers, led by the Revived Genomics of Personality Consortium, has identified over 1,200 different genetic variants associated with the 'Big Five' personality traits: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. This extensive study, combining data from 46 research cohorts and over a million people globally, found that these genetic variants are linked to a wide array of life outcomes, including mental and physical health, longevity, education, and career paths. While the study confirms a genetic component to personality, it also emphasizes that environmental factors, particularly social experiences, play a more significant role than genetics in shaping an individual's personality. The findings indicate that there is no single 'personality gene,' but rather many variants each contributing a microscopic influence.

Ig Nobel Prizes Held in Zurich for First Time, Stuart West Among Honorees

Ig Nobel Prizes Held in Zurich for First Time, Stuart West Among Honorees

The Ig Nobel Prizes, an annual satirical science awards ceremony, was held outside the U.S. for the first time in its 35-year history, taking place in Zurich, Switzerland. The shift in venue was due to concerns regarding attendees' ability to obtain visas. Ten research teams were honored for their unusual and imaginative contributions to science. Among the recipients were Stuart West from the University of Oxford and Catherine F. Talbot from the Florida Institute of Technology, who were recognized for their work in reconstructing the evolutionary history of kissing. Other awarded research included studies on cockroach milk, analyzing soil health using buried underwear, and the science of nose-blowing. The ceremony maintained its tradition of audience members throwing paper airplanes towards the stage.

Sitka Brown Bear Drowns During State-Run Research Project in Alaska

Sitka Brown Bear Drowns During State-Run Research Project in Alaska

A male brown bear, known locally as Tum-Tum, drowned in late July near Redoubt Falls, Sitka, during a state-run research project conducted by the Alaska Department of Fish and Game. The incident occurred while research staff were capturing and collaring brown bears at Redoubt Lake as part of a six-year project aimed at counting the bear population on Baranof Island. State wildlife biologist Stephanie Sell confirmed that the five-year-old bear, which was highly habituated, was darted and subsequently took a trail leading to saltwater. Despite immediate and extensive efforts by the staff, including rescue breathing and CPR, the bear could not be resuscitated. Following the incident, Fish and Game staff immediately ceased all capture operations in the area. Sell described the event as a 'highly unfortunate accident,' acknowledging the inherent risks involved in wildlife management and research for both personnel and animals.

Cope's Gray Tree Frogs Exhibit Poor Mating Choices Under 'Choice Overload' Conditions

Cope's Gray Tree Frogs Exhibit Poor Mating Choices Under 'Choice Overload' Conditions

A new study on Cope's gray tree frogs in Tennessee reveals that female frogs make suboptimal mating choices when presented with too many options. Researchers tested 60 female frogs in a sound chamber, offering either two, four, or eight recorded mating calls. Females typically prefer longer calls, which are linked to better survival odds for offspring. When only two calls were available, 77% of the frogs chose the longer, more desirable call. However, this percentage dropped to about half with four options and to only one in five when eight calls were presented. The study, published in iScience, also noted that decision-making time increased, and 17% of frogs confronted with eight calls made no choice at all.
