New Mygatt-Moore quarry research leads to prehistoric climate finds

Researchers analyzed over 2,300 fossil bones and found over 400 marks left by insects and snails, shedding light on paleo diversity and climate of the Jurassic period. The high number of insect traces suggests that dinosaur carcasses remained unburied for an extended period, providing valuable insights into prehistoric stench.

Two studies suggest strategies to help students at community colleges and broad access institutions

Research suggests that brief reading and writing exercises can alleviate concerns about sense of belonging, leading to increased continuous enrollment among socially disadvantaged students at broad-access institutions. These interventions may also help build up the resources and skills needed for college success.

Shaking light with sound

Scientists combine piezoelectric aluminium nitride with ultralow-loss silicon nitride integrated photonics to create a hybrid circuit for on-chip acousto-optic modulation. The technology enables wideband actuation with ultralow electrical power, opening up new possibilities for precision-demanding applications.

HIV alone not a risk factor for cavities in children

A Rutgers researcher has found that a weakened immune system, rather than HIV itself, contributes to the prevalence of dental cavities in children. The study, published in Scientific Reports, sampled nearly 300 children and found that those with normal immunity levels had lower cavity rates, regardless of HIV status

Polycatenanes in mesoscale

A Japanese research group led by Professor Shiki Yagai has successfully created polycatenanes, self-assembled molecule rings that can be observed under a microscope. By using atomic force microscopy, they confirmed the structure of poly[22]catenane made up of as many as 22 connected rings, reaching up to 500 nm in length.

Research raises concerns about firearm access for people with dementia

Research reveals that many caregivers of individuals with Alzheimer's and Related Dementias (ADRD) lack guidance on firearm safety, despite high rates of accidental shootings. The study emphasizes the need for healthcare providers to address firearm safety in the context of ADRD, providing routine counseling and access to resources.

SNMMI Image of the Year: Super-agers show resistance to tau and amyloid accumulation

Research at SNMMI 2020 Annual Meeting found super-agers have lower tau and amyloid pathology associated with neurodegeneration. This enables them to maintain their cognitive skills even at advanced ages. The study suggests a potential pathway for successful aging and developing novel treatments to tackle age-related diseases.

Prediabetes linked to increased risk of heart disease and death

A review of available evidence suggests that prediabetes is associated with a higher risk of all-cause mortality and cardiovascular disease in both the general population and patients with a history of heart disease. Screening and proper management of prediabetes may contribute to primary and secondary prevention of CVD.

Only a third of pediatricians fully follow guidelines on peanut allergy prevention

A study published in JAMA Network Open found that only 30% of US pediatricians fully implement recommended practices for preventing peanut allergy, with common barriers including lack of clinic time and parental fear. The 2017 guidelines aim to introduce peanut-containing foods at 4-6 months to reduce prevalence.

Early life stress is associated with youth-onset depression for some types of stress but not others

A meta-analysis of 62 studies and 44,000 participants reveals that eight specific types of early life stress are associated with an increased risk of developing depression in youth. These include emotional abuse, poverty, and death of a family member, while others like sexual abuse and physical abuse show stronger links to the condition.

Hyksos, 15th Dynasty rulers of Ancient Egypt, were an internal takeover

A study using chemical analysis reveals that the Hyksos rulers of Ancient Egypt were a multi-cultural group who rose to power from within. The research found that a large percentage of the population in the ancient capital city were non-locals who immigrated from various places, contradicting the common story of a sudden invasion.

COVID-19 'price gouging' could be prevented

A new paper from the University of Portsmouth argues that excessive pricing due to COVID-19 can be prevented by enforcing EU competition law and applying price controls. The research suggests that imposing fines may not be effective in addressing price gouging, as companies may continue to raise prices in the future.
