Professor Matei Ciocarlie wins Young Investigator Program grant for hands-on research

Professor Matei Ciocarlie has received a three-year Young Investigator Program grant to develop collaborative manipulation systems for human-robot teams. His research aims to create novel mechanisms that combine mechanical and computational intelligence, enabling robots to perform versatile tasks in cluttered or occluded settings.

Your handshake tells the story of your health

A study published in The Lancet found that firmness of hand grip is a better indicator of health than blood pressure. Researchers analyzed data from over 140,000 adults and found that reduced muscular strength measured by grip strength was consistently linked to early death, disability, and illness.

Game intelligence can be learned

Researchers at Chalmers University of Technology developed a mathematical theory on game intelligence in team sports. They studied former NHL player Nicklas Lidström's moves during games and found that he used principles such as minimizing the opponents' best alternative to gain an edge.

Octopus arm inspires future surgical tool

A robotic arm inspired by an octopus's flexible arms can bend, stretch and squeeze through cluttered environments, enabling surgeons to access remote areas of the body. The device manipulates soft organs without damaging them, reducing the need for multiple instruments.

Mining pollution alters fish genetics in southwest England

New research reveals that mining pollution has led to a significant reduction in the genetic diversity of brown trout populations in southwest England. The study found that these fish have adapted to live in water with high levels of metal contaminants, but this adaptation comes at the cost of reduced genetic variation.

College readiness declines when school's focus is improving test scores, study finds

A new study found that accountability sanctions in Texas led to a decline in college readiness, as schools focused on improving test scores rather than academic rigor. The researchers discovered that students were stigmatized by their school's negative reputation and faced limited social support from inexperienced teachers.

Survival from rare bone cancer remains low

A Loyola University Medical Center study found that among 205 cases of mesenchymal chondrosarcoma, more than half survived at least five years and 43 percent survived at least 10 years. Survival rates varied depending on tumor location, with axial tumors showing worse outcomes.

Can diet and exercise prevent muscle loss in old age?

A recent review of combined diet and exercise training trials found that the effects differ across studies, suggesting more research is needed to determine their benefits for older people. Exercise training and diet supplementation have been shown to be effective in preventing muscle loss, but little is known about their combined effects.

Political talk on Facebook mirrors political talk offline

A study published in Political Research Quarterly found that social media platforms don't break new ground among political discussion forums. Users with strong social connections tend to prefer like-minded discussions and tailor their privacy settings accordingly. In contrast, users who facilitate connections between different groups a...

Wetlands continue to reduce nitrates

Researchers found that wetlands created between tile-drained agricultural fields and rivers can remove 62% of nitrates from water. The slow flow of water through the wetland allows microbes to eliminate nitrate, reducing its emission as a greenhouse gas. Building a wetland is an effective long-term solution for reducing nitrate runoff.
