The phenomenon of regeneration was discovered over 200 years ago in the freshwater polyp Hydra. Until now, however, it was largely unclear how the orderly regeneration of lost tissues or organs is activated after injury. In its investigations of Hydra,…

Men with low testosterone who develop COVID-19 are at elevated risk of becoming seriously ill and ending up in the hospital, according to a new study.

New research reveals private equity firms that acquire physician-owned medical practices appear to be imposing measures to squeeze out more profits. It’s not clear whether these practices hurt clinical outcomes for patients. However, the findings raise…

New research has mapped the DNA from more than 150 species of native rodents from across Australia, New Guinea and Melanesian islands, painting a clearer picture of how they’re related and how they ended up spreading across the Pacific.

Be it magnets or superconductors: materials are known for their various properties. However, these properties may change spontaneously under extreme conditions. Researchers have discovered an entirely new type of such phase transitions. They display th…

Today, when an algorithm identifies a tumor in a tissue sample, it doesn’t reveal how it arrived at this result. And that does not inspire trust. Researchers are therefore pursuing a new approach.

Did the first ancestors of whales pick up where the mosasaurs left off 66 million years ago, after the extinction of all the large predatory marine reptiles? A study has looked into the possible convergences in morphology and behavior that may exist be…

A large amount of lungs donated cannot be used for transplantation. Researchers have conducted an animal study bringing hope that more donor lungs could be used in the future. The researchers have launched a pilot study to investigate whether the treat…

Scientists use genomic data to resolve the phylogeny of zygnematophyte algae and pinpoint several emergences of multicellularity in the closest known relatives of terrestrial plants.

The pandemic has impacted our lives in a multitude of ways, many of which will no doubt be felt for years to come. While many of those effects are clearly negative, researchers have identified at least one positive impact — our perception of natural s…

A molecular atlas of an Australian dragon’s brain sheds new light on over 300 million years of brain evolution.

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identif…

In the young population, arterial stiffness, an emerging risk factor for hypertension, indirectly raises blood pressure via an increase in insulin resistance but not via an increase in body fat, a new article concludes.

Researchers have partners detected unique fluorescence blinking patterns in experiments of electron transfer to single DNA molecules. They used these patterns to identify mRNA glioma point mutations in cell culture. The results of this work could help …

Researchers have characterized the new omicron variant BA.2.75, comparing its ability to evade antibodies against current and previous variants. The study suggests that BA.2.75 is not more resistant to antibodies than the currently dominating BA.5, whi…

A new platform takes on Huntington’s disease via an innovative approach.

Rsearchers who conducted their experiment in a Brisbane backyard have found an unprecedented methodology for the production of microspheres.

When researchers tested a large number of old toys and dress-up items made of plastic, 84 per cent of the items were found to contain toxins that can disrupt growth and development and reproductive capacities in children. These toxins are an obstacle f…

Researchers have used computer simulations to show that stable aromatic molecules can become reactive after absorbing light. The results may have long-term applications in such areas as the storage of solar energy, pharmacology, and molecular machines.

Astronomers have used NASA’s James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. The image shows how Webb’s powerful infrared …
