Moderate aerobic exercise in older adults shown to improve memory

A new study led by the University of Illinois at Urbana-Champaign found that one year of moderate physical exercise can increase the size of the brain's hippocampus in older adults. The increased hippocampal size is associated with improved spatial memory function. The researchers also discovered a correlation between increased hippoca...

Researchers discover giant crayfish species right under their noses

Researchers have discovered a new species of giant crayfish, Barbicambarus simmonsi, in Tennessee and Alabama, which is at least twice the size of its closest relative. The species was found under rocks in a creek and has distinctive 'bearded' antennae with setae that enhance sensory function.

Chemists document workings of key staph enzyme -- and how to block it

Scientists have determined the structure and mechanism of a key enzyme in Staphylococcus aureus that produces cholesterol and a virulence factor. This breakthrough could lead to new cholesterol-lowering drugs and antibiotics against staph infections, as well as treatments for parasitic diseases.

Researchers show how 1 gene becomes 2 (with different functions)

A team of researchers has successfully demonstrated the molecular evolution of two competing functions from a single gene, AFP III, which helps Antarctic fish survive in frigid waters. The study confirms the ancestry of antifreeze proteins and validates a decades-old hypothesis about gene duplication.

Large-scale study reveals major decline in bumble bees in the US

A large-scale study has found major declines in US bumble bee populations, with four species experiencing a 96% drop in relative abundance and a 23-87% loss of geographic range. The researchers attributed the decline to low genetic diversity, high infection rates with the parasite pathogen, and climate change.

Strategy, court specialization driving increase in smart-phone litigation

Research reveals that technology companies are targeting the US International Trade Commission (ITC) over federal district courts for smart-phone patent disputes due to its speed and expertise. The ITC's specialization in patent issues and streamlined procedure make it an attractive option for companies seeking a quick decision.

Study: Employers, workers may benefit from employee reference pool

A centralized reference pool could help employers and workers by providing a legal safe harbor for employees and allowing them access to references while also enabling recourse through a neutral third party. This system would promote the flow of accurate information with low transaction costs, making labor markets more efficient.

Microsensors offer first look at whether cell mass affects growth rate

University of Illinois researchers developed microsensors that can track individual cells' masses and divisions over time. They found that cells grow faster as they grow heavier, rather than at a fixed rate throughout the cell cycle. The sensors also allow for imaging and tracking of cellular processes in conjunction with changes in mass.

Long-extinct passenger pigeon finds a place in the family tree

Researchers used DNA from century-old specimens to identify the passenger pigeon's closest living relatives, revealing a unique bird with a distinct place in the evolutionary history of pigeons and doves. The study found that the passenger pigeon was not closely related to the mourning dove as previously thought.

New findings about wind farms could lead to expanding their use

Researchers have found wind farms' effects on local temperatures and proposed strategies for mediating those effects, increasing the potential to expand wind farms. The study identified two possible mediation strategies: low-turbulence rotors or locational deployment in regions with natural mixing in the atmosphere.

Study: Small firms need more access to credit during financial troubles

Research by University of Illinois finance professors Murillo Campello and Heitor Almeida finds that small firms face higher costs of financing when economic conditions worsen. They often re-invest profits before paying off creditors, leading to increased debt and potential financial distress.

A shot to the heart: Nanoneedle delivers quantum dots to cell nucleus

University of Illinois researchers have created a tiny needle that can deliver quantum dots directly into a cell's nucleus, allowing for the study of internal environments and cellular processes. This breakthrough technique uses electrical potential to control the release of molecules and offers precise monitoring capabilities, opening...

Pediatric vaccine stockpile policies need to be revisited, researcher says

Research suggests that the current six-month rotating vaccine stockpile policy may not be optimal for achieving herd immunity. A new stochastic model proposes flexible policies to minimize vaccine shortage risks while maintaining coverage rates. The study's findings highlight the need for differentiated stockpile levels based on diseas...

Economic status, genetics together influence psychopathic traits

Researchers found that children with a specific serotonin transporter gene variant are more likely to exhibit psychopathic traits if they grow up poor. These traits include lack of empathy, arrogance, and deceitfulness. The study suggests that socioeconomic environment influences the expression of this genetic trait.
