Medicare overpayments for graduate medical education could total $1.28 billion annually

A study published in JAMA Internal Medicine found that Medicare overpaid hospitals by an estimated $1.28 billion annually for Graduate Medical Education (GME) programs. Capping GME payment rates could free up over $1 billion, potentially addressing doctor shortages and strengthening the physician workforce in underserved areas.

Ethiopian parents can't make up for effects of life shocks on children by spending more on education

New research from Lancaster University and Heriot-Watt University reveals that Ethiopian parents' attempts to level the playing field for disadvantaged children by investing more in education are ultimately ineffective. The study found that even with greater investments, low-ability outcomes persist later in childhood.

Icaros: Flight simulator home trainer

Researchers at the German Sport University explored the effects of full-body exergaming in VR on cardiovascular system and strength endurance. Results showed that VR-based training had little to no cardiovascular benefit but created incentives for increased physical activity, motivating users to take up exercise.

Early humans evolved in ecosystems unlike any found today

Researchers found that ancient plant and animal communities differed significantly from today's, with a greater diversity of megaherbivores and non-ruminant species. The study suggests that environmental changes driven by grassland expansion and arid climate pulses may have influenced human evolution.

Violence linked to social isolation, hypervigilance and chronic health problems

Exposure to violence negatively impacts physical and psychosocial health in urban adults. Social isolation and loneliness are associated with limited physical activity, poor nutrition, and increased risk of cardiovascular disease. Chronic hypervigilance also linked to increased blood pressure, memory impairment, and anxiety disorders.

The benefits of updating agricultural drainage infrastructure

A new study from Iowa State University highlights the need to update agricultural drainage infrastructure, which can benefit crop production and the environment. The research recommends installing higher capacity pipes and implementing long-term conservation practices, such as denitrification wetlands, bioreactors, and saturated buffers.

Young infants with fever may be more likely to develop infections

Researchers found that young infants with fevers are more likely to develop serious bacterial infections. Infants under eight weeks old have a doubled risk of developing such infections. Parents are encouraged to seek immediate medical attention if their child develops a fever over 100.4 degrees Fahrenheit.

The story of thalidomide continues

A recent study reveals that thalidomide causes developmental abnormalities by inducing the breakdown of two types of p63 proteins, leading to limb defects and ear damage. The findings may contribute to the re-emergence of safe, non-teratogenic thalidomide-derived drugs as cancer and inflammatory disease treatments.

Costs of natural disasters are increasing at the high end

The economic cost of natural disasters has increased disproportionately for major events like hurricanes and tornadoes, while lesser events have seen less growth. Climate change is driving these increases, with the top 1% of damages estimated to rise by $26 million annually.

New silk materials can wrinkle into detailed patterns, then unwrinkle to be 'reprinted'

Researchers at Tufts University have developed silk materials that can form highly detailed patterns in a matter of seconds, which can be erased and reformed using vapor, enabling reversible printing and thermal regulation. The technology has potential applications in optical electronic devices, biomedical materials, and smart textiles.

Predicting terror activity before it happens

A new predictive model can forecast a terror organization's future violence after just 10 attacks, allowing security forces to identify and neutralize the most destructive groups. The model, developed by Northwestern University researchers, uses data from publicly available sources like the Global Terror Database.
