Leaving small kidney stones behind causes problems later

When surgeons remove patients' kidney stones, they typically leave behind small stones that appear not to be causing problems. However, a new randomized controlled study has shown that leaving these asymptomatic stones behind significantly increases the risk of a patient's relapse in the following five years.

Study uncovers what happens inside artery plaque to trigger strokes

Researchers have genetically sequenced carotid plaque tissue collected from patients within days after a stroke. When compared to stable plaque, researchers discovered the tissues from recent stroke victims contained messenger RNA that can cause inflammation and processes that degrade a key portion of the plaque that protects against rupture.

Hubble sees red supergiant star Betelgeuse slowly recovering after blowing its top

The star Betelgeuse appears as a brilliant, ruby-red, twinkling spot of light in the upper right shoulder of the winter constellation Orion the Hunter. But when viewed close up, astronomers know it as a seething monster with a 400-day-long heartbeat of regular pulsations. This aging star is classified as a supergiant because it has swelled up to an astonishing diameter of approximately 1 billion...

Simplified voice box enriches human speech

The evolution of the human larynx contributed to the stable voices we use to communicate. The morphological changes do not include the addition of structures but rather the loss of specific vocal folds or cords in the larynx, providing a stable voice quality and controllable voice pitch used when singing or speaking.

Broadly neutralizing antibody that protects Syrian hamsters against SARS-CoV-2 Omicron variants

Researchers have demonstrated that ZCB11, a broadly neutralizing antibody derived from a local mRNA-vaccinee against the spreading Omicron variants of SARS-CoV-2, displays potent antiviral activities against all variants of concern (VOCs), including the dominantly spreading Omicron BA.1, BA1.1 and BA.2. Critically, either prophylactic or therapeutic ZCB11 administration protects lung infection...

How an urban bat differs from a rural bat

Some bat species are more likely to be found in cities than in the countryside. A scientific team has now investigated which characteristics are typical for urban and rural bats. The team found that bat species with higher affinity to cities are characterized by relatively low frequencies and long durations of their echolocation calls, a small body size and flexibility in the choice of their...

Building the best zeolite

A professor of chemical and biomolecular engineering has summarized methods of making zeolites in the lab and examined how the emergence of data analytics and machine learning are aiding zeolite design.

Safe havens for cooperation

Whether networks with a high level of cooperation emerge in a community depends on how quickly individuals leave -- for example, because they are exploited by others. Researchers investigated this problem by modeling a well-known cooperation game. They consider a spatial network, where players can relocate between different patches if they judge the local conditions to be unfavorable.
