Largest genetic study of epilepsy to date provides new insights on why epilepsy develops and potential treatments

A massive genetic study has identified specific DNA changes that increase the risk of developing epilepsy. The research found 26 distinct areas in our DNA involved in epilepsy and proposed alternative drugs targeting these genes. The findings may inform better diagnosis, classification, and treatment strategies for epilepsy.

Student engagement improves calculus class outcomes among undergraduates

A randomized trial involving 811 undergraduate students found that collaborative learning and student engagement significantly improved calculus concept understanding and grades. The study, conducted over three semesters, used an engagement model that cultivates mathematical habits of mind, resulting in a 11% increase in pass rates.

Study: ‘Suicidal’ mechanism discovered in ion channel receptors enables the sensing of heat and pain

University at Buffalo researchers have unraveled the complex biological phenomena underlying human temperature and pain sensitivity. They found a previously unknown 'suicidal' reaction in ion channel receptors that enables them to sense heat and pain, leading to potential breakthroughs in pain management.

How little things can reduce hip fractures

A new Australian study found that implementing simple bone-strengthening strategies throughout the community can lead to a substantial decrease in hip fractures. The study analyzed data from over 3000 individuals aged 60+ and showed a 45% decline in hip fractures despite only a 3% increase in bone mineral density.

Evolving chemical system changes its environment

Researchers from the University of Groningen created a synthetic system that exhibits eco-evolutionary dynamics, where replicators adapt to their environment and undergo natural selection. The system consists of two different ring sizes that compete for a common building block, with one replicator emerging as dominant in certain enviro...

Geisel School of Medicine receives $16.2 million grant to study healthcare inequity in Alzheimer’s disease

A team of researchers at Dartmouth's Geisel School of Medicine has been awarded a $16.2 million grant to study inequities in healthcare for adults with Alzheimer’s disease and related dementias, with a focus on racialized and marginalized populations. The five-year renewal grant will explore how intersecting identities affect treatment...

Sylvester researchers help identify mechanisms by which multiple myeloma escapes targeted immunotherapy

Researchers at the University of Miami Miller School of Medicine identified distinct genomic events responsible for resistance to anti-BCMA and anti-GPRC5D immunotherapies in multiple myeloma. Mutations in the extracellular domain of BCMA impede T-cell binding without affecting protein expression or downstream signaling.

Large proportion of Michigan’s C. jejuni infections are caused by antibiotic resistant strains

Researchers at Michigan State University have found that over half of Campylobacter jejuni infections in Michigan are caused by antibiotic-resistant strains, which can lead to severe complications and death. The study's findings highlight the importance of food hygiene and safety, particularly in rural areas where exposure to animals a...

Researchers predict film scores by the activity of facial muscles

A study published in Frontiers in Neuroscience found that the activity of zygomaticus major, heart rate variability, and EEG indicators can predict film scores. The researchers used a machine learning model to analyze physiological data from 21 participants who watched short films and rated them on a scale from 1 to 10.
