Even a small temperature drop in the tropical climate of Singapore increases the risk of heart attack among people aged 65 and above.

An updated analysis of American COVID-19 deaths throughout 2021 highlights a continued drop in overall life expectancy as well as persistent disparities by race and ethnicity.
What goes on inside planets like Neptune and Uranus? To find out, an international team conducted a novel experiment. They fired a laser at a thin film of simple PET plastic and investigated what happened using intensive laser flashes. One result was that the researchers were able to confirm their earlier thesis that it really does rain diamonds inside the ice giants at the periphery of our solar...
Researchers have developed a novel method of using artificial intelligence and machine learning to make monitoring soil moisture more energy and cost efficient. The software learns over time how to make the best use of available network resources, which helps produce power efficient systems at a lower cost for large scale monitoring compared to the existing industry standards.
An unusual protein structure known as a 'rippled beta sheet,' first predicted in 1953, has now been created in the laboratory and characterized in detail using x-ray crystallography. The new findings may enable the rational design of unique materials based on the rippled sheet architecture.
A comprehensive historical assessment of knowledge and beliefs about disease transmission sheds light on why influential institutions worldwide took too long to recognize that COVID-19 is primarily airborne. The authors trace this deadly resistance one hundred years back in history, to the rejection of sickly air called 'miasma,' the rise of germ theory and our own stubborn tendency to retain...
Researchers have discovered that the motion of chromatin, the material that DNA is made of, can help facilitate effective repair of DNA damage in the human nucleus -- a finding that could lead to improved cancer diagnosis and treatment.
Many transgender parents with children between one-and-a-half and six years of age hesitate to label their child's gender identity, according to new research. In addition, the results suggest that many children with transgender parents play in ways that conform to gendered societal expectations, while others play in more gender-expansive ways.
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, an interdisciplinary research team was able to show how wound healing signals released upon injury are converted into specific signals of pattern...
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 concerning parallels with the rapid growth of private equity acquisition of nursing homes and hospital systems.
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 the phenomenon of quantum entanglement involving many atoms, which previously has only been observed in the realm of few atoms.
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 between these two groups of large marine predatory animals.
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 treatment will have the same positive effects on human beings.
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 spaces changed.
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 identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool for...
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 simplify surgical biopsies, enable real-time targeted therapy, and advance scientific understanding of cancer progression.
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, which is positive news.
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.
