A new species of Australian bush tomato described from the Garrarnawun Lookout in Judbarra National Park provides a compelling example of the need to provide equal and safe access to natural places. Bucknell University postdoctoral fellow Tanisha Williams and biology professor Chris Martine led the study following a chance encounter with an unusual population of plants during a 2019 research expedition to the Northern Territory.

A dilemma for policymakers: The world needs to start preparing for the weather-related disasters happening with increasing frequency and intensity due to climate change. World leaders are proposing measures to quickly reduce emissions and build resilience. Yet, many voters oppose spending on measures to prevent or mitigate disaster.

Have you ever eaten chicken feet? If you haven't, you might be surprised to learn there's actually quite a bit of flesh down there. And scales too! They're wonderful—and informative—pieces of engineering.

Among domestic mushroom pickers in Germany it goes without saying that many edible mushrooms in our forests are still contaminated with radionuclides as a result of the 1986 Chernobyl nuclear disaster. Less well known is that mushrooms can also accumulate other heavy metals.

Classical mechanics is the framework for studying motion of objects under the influence of forces. Its domain of applicability is limited to the macroscopic world (i.e., not applicable in the atomic/subatomic world) and to motion of objects with speeds much smaller than the speed of light.

Surface solar radiation (Rs) data is essential information for the development of solar power usage to mitigate the ongoing climate change. To meet China's carbon neutrality goal, China has invested and planned heavily in solar photovoltaic systems.

After over three years of upgrade and maintenance work, the Large Hadron Collider began its third period of operation (Run 3) in July 2022. Since then, the world's most powerful particle accelerator has been colliding protons at a record-breaking energy of 13.6 TeV. The ATLAS collaboration has just released its first measurements of these record collisions, studying data collected in the first half of August 2022.

The Earth's deep-sea trenches are some of the least explored places on Earth—as they are very difficult to access, are pitch black and the pressure is extremely high. Collecting samples and making reliable measurements of the processes that regulate the turnover of organic material in the deep is therefore difficult.

A major impediment to industrial urea synthesis is the lack of catalysts with high selectivity and activity. Prof. Yuliang Li (Institute of Chemistry, Chinese Academy of Sciences) and coworkers reported a new catalyst system suitable for the highly selective synthesis of industrial urea by in-situ growth of graphdiyne on the surface of cobalt-nickel mixed oxides.

Making an intentional effort to recognize positive life events and achievements while gathering for food and drink will leave you feeling more socially supported, new research shows.

A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But its potential has faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to embrace it. With silicon nearly maxed out in its ability to accommodate faster computing, the next big nanoelectronics platform is needed now more than ever.

People who turn to social media to escape from superficial boredom are unwittingly preventing themselves from progressing to a state of profound boredom, which may open the door to more creative and meaningful activity, a new study of the COVID pandemic shows.

The abundant carbon on Earth might offer a rich, renewable resource for clean, sustainable energy. The technology—called carbon-based electrochemical catalysis—that could make green energy conversion possible exists, according to an international collaboration investigating recent advancements, but is not ready for broad application.

Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single-celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot.

Researchers from Rollins College, University of Cambridge, and Harvard University published a new Journal of Marketing article that examines the timing effects of payment requests in pay-what-you-want pricing situations.

Here it is again: the merry, festive Christmas season with its glitter balls, tinsel and the typical "Ho Ho Ho!" Holding onto his red belly, Santa grins and laughs at us from everywhere. Like Halloween pumpkins and clowns, Santa is one of our most popular cultural symbols associated with laughter.

A collaboration of scientists from RMIT, ANSTO and the CSIRO has published pioneering research that brings new insights into intrinsically disordered proteins and protein regions (IDPs)/ (IDRs) and how they behave under various physiological processes.

Mothers in the samples from the U.K. and Uganda have different attitudes toward parenting, but while on a group level the experience and development of their infants sometimes aligns with parenting attitudes, surprisingly, it did not always show such variation, according to a new study published this week in the open-access journal PLOS ONE by Eve Holden and Katie Slocombe of University of York, U.K., and colleagues.

A new study from North Carolina State University finds that biology textbooks have done a poor job of incorporating material related to climate change. For example, the study found that most textbooks published in the 2010s included less information about climate change than they did in the previous decade—despite significant advances in our understanding of how climate change is influencing ecosystems and the environment.

In experiments using made-up tweets, participants rated the trustworthiness of faces paired with positive news headlines more highly than faces paired with negative headlines.

A study published in Science Advances by an international team of scientists provides clear evidence that marine phytoplankton are much more resilient to future climate change than previously thought.

In the largest ever review of teacher expertise, including data from over 1,000 teachers from around the world in primary and secondary school education, 73 features common to many expert teachers have been identified.

Snow cover is a vital source of water for industry, agriculture and human consumption. Records show that last winter's snow cover in the Alps was less than it has been since 2001. This Copernicus Sentinel-3 image captured on December 18, 2022 shows the wide-coverage of snowfall which hopefully bodes well for the coming year.

Since it launched on December 25th, 2021, the James Webb Space Telescope (JWST) has taken the sharpest and most detailed images of the universe, surpassing even its predecessor, the venerable Hubble Space Telescope. But what is especially exciting are the kinds of observations we can look forward to, where the JWST will use its advanced capabilities to address some of the most pressing cosmological mysteries. For instance, there's the problem presented by high-redshift supermassive black holes (SMBHs)... Читать дальше...

Here's a thorny problem: What if life doesn't always appear on planets that can support it? What if we find more and more exoplanets and determine that some of them are habitable? What if we also determine that life hasn't appeared on them yet?
