Childhood lead exposure remains an unresolved issue across the US, particularly from lead paint in older homes. Should we be worried about our health if we live in a house with lead-based paint?

The periodic table of elements is widely recognized, but there are hundreds of beautiful and different periodic table reinterpretations.

[This is a transcript of the video embedded below. Some of the explanations may not make sense without the animations in the video.] Cold fusion could save the world. It'd be a basically unlimited, clean, source of energy. It sounds great. There's just one problem: it's not working. Indeed, most physicists think it can't work even in theory. And yet, the research is making a comeback. So, what's going on? What do…

An international research team gained new insights into the chemical properties of the superheavy element flerovium—element 114—at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The measurements show that flerovium is the most volatile metal in the periodic table. Flerovium is thus the heaviest element in the periodic table that has been chemically studied.

A team of researchers from the University of Toronto's Faculty of Applied Science & Engineering has leveraged quantum mechanics to optimize the active layer within a device known as an inverted perovskite solar cell—a technology that could one day result in mass-market solar cells that a fraction of those currently on the market.

For the first time, Stanford researchers have found a way to create and stabilize an extremely rare form of gold that has lost two negatively charged electrons, denoted Au2+. The material stabilizing this elusive version of the valued element is a halide perovskite—a class of crystalline materials that holds great promise for various applications including more-efficient solar cells, light sources, and electronics…

Calculations provide a glimpse inside carbon nuclei, revealing the presence of three clusters resembling helium nuclei

Physicists have achieved a record-setting level of electron mobility in a thin film of ternary tetradymite. Materials like this will be essential for more efficient and sustainable electronic devices that can do more work with less power.

Scientists led by an Oregon State University chemistry researcher are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.

Heavy elements like gold and silver are believed to be created when neutron stars collide, but new research suggests these collisions may also spur nuclear...

LK-99 is the name of the material that is being hotly debated around the world these days: A Korean research group published results at the end of July 2023 on the preprint server arXiv suggesting that it could be a superconductor even at room temperature and normal atmospheric pressure. Superconductors known to date retain their properties only when either cooled to very low temperatures or subjected to extremely…

The recent report of superconductivity in nitrogen-doped lutetium hydride at near-ambient pressures and temperatures has attracted great attention but also continuing controversy. Several experimental groups have reported no observation of superconductivity at these conditions in Lu-N-H samples they have prepared. To address this issue, we have carried out a series of studies of phases in the Lu-N-H system using a…

In this free webinar, learn how the trajectory of the drug discovery landscape is changing in response to the emerging, next generation technologies. Attendees will gain insights into how data-informed and AI-guided chemical library design opens the door for small molecules to address "undruggable" targets and novel modalities. The featured speakers will discuss how leading-edge machine learning and cheminformatics…

ChatGPT and Generative AI have become, seemingly overnight, two of the hottest topics being discussed in tech circles. Some of...

Iron meteorites of the solar system are composed of parent cores belonging to the earliest credited bodies of the environment. The cores are formed in two isotopically distinct reservoirs including non-carbonaceous and carbonaceous types in the inner and outer solar system. In a new report now published in Science Advances, Bidong Zhang and a team of scientists in Earth, Planetary and Space Sciences, at the…

Magnets produce magnetic fields and attract metals like iron, nickel and cobalt. They're used in all sorts of applications but how are they made and how do they work?

Skipping ahead in a line is rude, but sometimes it's acceptable. Especially for salt.

Nuclear fission is a substantial part of the world's energy mix, but out in the broader universe, fission is much harder to come by. Until now.

In new research, Los Alamos National Laboratory theoretical physicist Matthew Mumpower and his colleagues analyzed r-process element abundances previously observed in stars.

An international team that includes researchers from the University of Toronto's Faculty of Applied Science & Engineering has created a perovskite solar cell that can stand up to high temperatures for more than 1,500 hours—a key milestone as this emerging technology moves closer to commercial application.
