Satellites cast critical eye on coastal dead zones

A dead zone in the ocean is as bad as it sounds, and having no information about dead zones' scope and path is worse. However, scientists at Michigan State University (MSU) have discovered a birds-eye method to predict where, when, and how long dead zones could persist across large coastal regions.

What shapes the composition of microbes in a warbler's gut?

Differences among the collection of bacteria and other microorganisms that live within birds' digestive tracts—their gut microbiomes—are not primarily driven by diet diversity, contrary to a recently proposed hypothesis. Instead, a team of researchers from Penn State has found that evolution may play a larger role in explaining these differences, which could potentially have implications for...

Astrophysicists chronicle the history of mathematical cosmology

RUDN University astrophysicists have gathered the most important discoveries of modern cosmology from 1917 to our time. The collected data became an introduction to Philosophical Transactions of the Royal Society A in two parts: from 1917 to 1980 and from 1980 to our time.

Children in child protection need more say about their care, says study

New Australian Catholic University (ACU) research shows that more must be done to support children's participation in child protection to ensure they have a voice when making decisions about their protection. ACU social work lecturer and study lead Dr. Elise Woodman said the new research revealed gaps between policy and practice.

Shining a new light on the importance of a critical photosynthesis pathway in plants

Photosynthesis is one of the most important chemical reactions, not just for plants but also for the entire world. The impact and thus the importance of photosynthesis can scarcely be underestimated. Thus, it makes sense that science has long been fascinated by the reactions and physical phenomena that make photosynthesis occur. One of these phenomena is the ferredoxin/thioredoxin (Fd/Trx)...

A combination of ultrasound and nanobubbles allows cancerous tumors to be destroyed without invasive treatments

A new technology developed at Tel Aviv University makes it possible to destroy cancerous tumors in a targeted manner, via a combination of ultrasound and the injection of nanobubbles into the bloodstream. According to the research team, unlike invasive treatment methods or the injection of microbubbles into the tumor itself, this latest technology enables the destruction of the tumor in a...

Research to mend broken bones, test implantable devices, and inspire future explorers on way to ISS

While millions of Americans plan for the upcoming holidays, a variety of critical research and supplies will head to the International Space Station (ISS) as part of SpaceX's 26th Commercial Resupply Services mission (SpaceX CRS-26). The SpaceX Dragon spacecraft is scheduled for launch onboard a Falcon 9 rocket to the space station no earlier than November 22, 2022, from Launch Pad 39A at NASA's...

Mapping Lyme disease across western North America

Tick bites transmit Lyme disease. But even knowing where these ticks live doesn't necessarily mean you can predict the disease in humans. It's only one part of a broader picture which includes human behavior and the habits of the parasite's carriers.

Researchers identify last remaining steps in the biosynthesis of tropane alkaloids from coca

Tropane alkaloids are a particular class of plant-derived compounds that have been exploited by mankind since the domestication of medicinal plants. The distribution of these alkaloids is scattered amongst the flowering plants and the two most studied families include those from the Solanaceae (tomato, tobacco, potato relatives) and the Erythroxylaceae (coca). The WHO lists several tropane...

The Eocene rise of eastern Tibet drove an ancient monsoon that modernized Asian biodiversity

Today East Asia, and in particular the Hengduan Mountains and other parts of southwestern China, hosts several of Earth's great biodiversity "hotspots." A biodiversity hotspot is where very large numbers of unique species are under threat of extinction, and so are conservation priority areas. However, to understand how best to look after this diversity we need to understand what created it and how...
