Harpoon heads, sweeping tails: How predatory mosquito larvae capture prey

Predatory mosquito larvae employ two distinct methods to capture prey: one involves a harpoon-like head-propulsion action, while the other uses a sweeping tail to snare insects. This new research provides insight into the behavior of these tiny predators and their ability to feed on other aquatic insects.

Orthopedic surgery patients do fine without opioid painkillers

A McMaster University study found that switching to non-opioid painkillers after surgery can significantly reduce opioid consumption and improve patient outcomes. The six-week study enrolled 193 patients who received either standard opioid-based painkillers or a combination therapy of naproxen, acetaminophen, and pantoprazole.

Study: Decreased proteins, not amyloid plaques, tied to Alzheimer’s disease

Researchers from the University of Cincinnati found that low levels of soluble amyloid-beta protein in the brain, rather than its buildup into plaques, are associated with cognitive decline and Alzheimer's disease. Patients with high levels of soluble amyloid-beta showed improved cognitive outcomes, contradicting previous theories.

Driving high? Chemists make strides toward a marijuana breath analyzer

A UCLA team has made strides toward developing a handheld tool similar to an alcohol Breathalyzer that can detect THC on a person's breath after they've smoked marijuana. The device uses oxidation to create an electric current, with the strength of the current indicating how much psychoactive compound is present.

Bad roads reduce trade volumes by 18%

A study published in Journal of Urban Economics found that bad roads in border regions increase travel time and cost, reducing international trade volumes by 18%. Underinvestment in transport infrastructure also leads to a 'border effect', where trade between regions in different countries is lower than within the same country.

Finding an RNA target and tool to fight premature aging

Scientists have identified long interspersed nuclear element-1 (L1) RNA as a promising new target for treating progeroid syndromes. Increased L1 RNA expression in cells from patients with these disorders led to deactivation of an enzyme, causing cell aging.

Ancient ice age valleys offer clues to future ice sheet change

A new study found that ancient ice age valleys in the North Sea formed rapidly, within hundreds of years, and transported vast amounts of meltwater away from under the ice. This process has implications for how glaciers may respond to climate warming today.
