At-risk middle schoolers: A good investment

A three-year course in the stock market and investing resulted in improved attendance and academic performance among at-risk middle school students. The program, which allowed students to buy shares of stock by improving their grades and attendance, showed statistically significant gains in vocabulary, reading comprehension, and applie...

Carnegie Mellon and U. of Pittsburgh create tool to understand neuron rhythms, learning

Researchers at Carnegie Mellon and University of Pittsburgh have created a new method to calculate the phase-resetting curve (PRC) of living neurons, which can help elucidate mechanisms for neural synchrony and study learning. The tool combines computational and experimental approaches to simplify complex dynamics of single neurons.

Research shows overfishing of sharks key factor in coral reef decline

A new study reveals that overfishing of sharks triggers a domino effect of changes in abundance, contributing to the degradation of Caribbean reefs. The researchers found that sharks play a crucial role in maintaining the stability of the ecosystem, and their removal can lead to a decline in plant-eating fish populations.

Sacred constant might be changing

Research by Dr. Michael Murphy suggests that the fine structure constant, governing electromagnetic forces, may have changed over time by about one part in two-hundred-thousand during the last 10 billion years. This finding challenges existing knowledge and could have significant implications for our understanding of the universe.

Liver may be source of 'good' cholesterol

Researchers at Wake Forest University School of Medicine have found that the liver is the main source of high-density lipoprotein (HDL), or 'good' cholesterol. This discovery could lead to new treatments for raising HDL levels, particularly in individuals with less severe cholesterol disorders.

'Born-again' stars reveal how the earth was created

A recent study led by Professor Albert Zijlstra has found that up to 0.1% of a star's mass can be expelled during re-ignition, equivalent to 300 times the mass of Earth. This discovery suggests that part of the carbon in the universe may have come from these events, providing new insights into the formation of our planet.
