A metabolic enzyme that has been studied for more than 70 years has a hidden second function – unwinding RNA and promoting cell cycle progression – beyond its role in energy production, according to new research led by the University of Surrey. Phosphofructokinase (PFK) is the “gatekeeper” of glycolysis, an ancient and evolutionarily conserved metabolic pathway that breaks down sugars to produce energy. In the yeast Saccharomyces cerevisiae, PFK is composed of two subunits, Pfk1 (α) and Pfk2 (β). Although both have long been understood as metabolic partners, Sally and her team discovered that Pfk2 has entirely different abilities. It…

Routine newborn screening (NBS) has revolutionized early detection of disease. However, traditional biochemical tests are limited in the range of symptoms that can be identified at birth. Next-generation sequencing is being investigated as a complementary screening tool. Reviews published in pediatric survey examines how next-generation sequencing can extend NBS from a single-disease assay to a genome-enabled multi-disease screening approach. Each year, millions of newborns undergo routine screening as a preventive strategy to detect genetic disorders before symptoms appear. Newborn screening (NBS) programs have traditionally relied on biochemical markers to identify specific groups of treatable conditions and have achieved remarkable success…

For more than 20 years, scientists have been studying a class of anti-cancer drugs known as CD40 agonist antibodies. Early experiments suggested that these treatments powerfully activate the immune system and may help destroy cancer cells. But people’s results were disappointing. Clinical trials showed only modest efficacy, and the drugs often caused severe side effects, including widespread inflammation, dangerously low platelet levels, and liver damage. These reactions occurred even at relatively low doses. In 2018, researchers led by Jeffrey V. Ravetch of Rockefeller University reported a potential groundbreaking discovery. The research team redesigned the CD40 agonist antibody to improve efficacy…

Undersecretary Robert F. Kennedy Jr. introduced several high-profile changes to U.S. vaccine regulations and recommendations, often met with fierce opposition from the medical community and others. After the U.S. government took the surprising action earlier this year to eliminate routine recommendations for six vaccines in childhood immunization schedules, and following several controversial developments last year, lawsuits from the American Academy of Pediatrics (AAP) and others have dealt a blow to HHS’ attempts to upend immunization practices in the United States. In a preliminary ruling, a federal judge in Boston blocked key parts of HHS’ vaccination program, finding that the agency…

Recent case reports published in Sexual medicine journal This paper details the experiences of two men who were relieved of a rare debilitating condition caused by ejaculation. Patients who suffered from severe flu-like cognitive symptoms after orgasm experienced significant improvement after taking antidepressants. These discoveries provide potential treatment options for diseases for which there are currently no standard treatments. Post-orgasmic illness syndrome is a medical condition characterized by physical and cognitive symptoms that occur immediately after experiencing an orgasm. People with this condition often report extreme fatigue, muscle weakness, fever, and difficulty concentrating. These symptoms usually last between 2 and…

A new study from UCLA Health reports that long-term exposure to the pesticide chlorpyrifos in residential areas is associated with a significantly increased risk of Parkinson’s disease. People living in areas with continuous exposure were more than 2.5 times more likely to develop the condition. Research published in journals molecular neurodegenerationcombines extensive human data with laboratory experiments showing how pesticides damage brain cells that produce dopamine. Taken together, these results provide biological evidence supporting an association between chlorpyrifos exposure and Parkinson’s disease. Nearly 1 million people in the United States have Parkinson’s disease. Parkinson’s disease is a progressive neurological disease…

Recent research published in journals deviant behavior Mapping the warning signs and organizational flaws that precede a deadly attack by a man who identifies as an involuntary bachelor. Researchers worked backwards from four different tragedies to identify a chain of severe social isolation, untreated mental health problems, and missed opportunities for intervention. These insights provide a roadmap for recognizing the red flags of misogynistic extremism and deterring future acts of mass violence. The Internet is home to a vast number of communities, some of which are united by common grievances. One such group is the “incel” subculture. This is a…

A federal judge in Boston on Monday stalled a key part of Health Secretary Robert F. Kennedy Jr.’s campaign to reshape U.S. vaccine policy, saying the Trump administration likely violated the law. Judge Brian E. Murphy issued a preliminary ruling that President Kennedy’s reconstitution of a key vaccine advisory committee and changes to the childhood vaccination schedule made in January were likely illegal. Specifically, the court ruled that these policy changes violated the Administrative Procedure Act, which governs how federal agencies should consider and implement policy changes. The decision is not final, but it is a blow to the Trump…

A longitudinal study of infants aged 12 to 18 months found that higher skin carotenoid concentrations at the start of the study predicted trends in improved cognitive development by 30 months. These infants also showed significant improvements in fine motor skills throughout the 12-month period, and improved ability to understand spoken language later in this period. The study was published in the Journal of Cognitive Enhancement. Skin carotenoids are natural pigments that accumulate in human skin after being ingested in the diet. They are primarily obtained from fruits and vegetables rich in carotenoids, such as carrots, sweet potatoes, spinach, and…

A compound in cannabis may help reduce alcohol dependence and withdrawal symptoms, a new study in animals suggests that the substance can protect the brain from damage caused by heavy drinking. This study was published in the journal neuropsychopharmacology. Alcoholism remains a serious global health problem. People with alcohol use disorders often struggle with uncontrolled drinking and experience severe withdrawal symptoms when they try to quit. Several medications exist to help treat alcohol dependence, but many have limited effectiveness or cause unwanted side effects. A potential alternative is cannabidiol (CBD), a natural compound found in the cannabis plant. Unlike THC,…
