'Tug of war' tactic enhances chemical separations for critical materials

Science Daily - 04/04/2024
Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

NASA's Webb probes an extreme starburst galaxy

Science Daily - 04/04/2024
A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.

New tools reveal how genes work and cells organize

Science Daily - 04/04/2024
Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.

Large language models respond differently based on user's motivation

Science Daily - 04/04/2024
A new study reveals how large language models (LLMs) respond to different motivational states. In their evaluation of three LLM-based generative conversational agents (GAs)--ChatGPT, Google Bard, and Llama 2, scientists found that while GAs are able to identify users' motivation states and provide relevant information when individuals have established goals, they are less likely to provide guidance when the users are hesitant or ambivalent about changing their behavior.

For mining in arid regions to be responsible, we must change how we think about water

Science Daily - 04/04/2024
In an unprecedented study of the South American 'Lithium Triangle,' hydrologists discover that not all water responds the same way to environmental change and human use.

New sunflower family tree reveals multiple origins of flower symmetry

Science Daily - 04/04/2024
A new sunflower family tree used skimmed genomes to increase the number of species sampled, revealing that flower symmetry evolved multiple times independently, a process called convergent evolution, among the members of this large plant family.

Developing a vaccine for the 'zombie drug' xylazine

Science Daily - 04/04/2024
Chemical biologists design an early 'proof-of-concept' vaccine that could lead to the first effective treatment of xylazine overdose in people.

Talking politics with strangers isn't as awful as you'd expect, research suggests

Science Daily - 04/04/2024
Individuals underestimate the social connection they can make with a stranger who disagrees with them on contentious issues, a new research paper suggests.

Evolution in action? New study finds possibility of nitrogen-fixing organelles

Science Daily - 04/04/2024
A new study finds that UCYN-A, a species of nitrogen-fixing cyanobacteria, may be evolving organelle-like characteristics.

Early dinosaurs grew up fast, but they weren't the only ones

Science Daily - 04/04/2024
The earliest dinosaurs had rapid growth rates, but so did many of the other animals living alongside them, according to a new study.

Working outside the typical 9-5 in younger adulthood may be linked with worse health decades later

Science Daily - 04/04/2024
The hours you work earlier in life may be associated with worse health years later, according to a new study.

Demand for critical minerals puts African Great Apes at risk

Science Daily - 04/04/2024
A recent study shows that the threat of mining to the great ape population in Africa has been greatly underestimated.

Immunotherapy for Alzheimer's disease shows promise in mouse study

Science Daily - 04/04/2024
Scientists have shown that treating mice with an antibody that blocks the interaction between APOE proteins (white) sprinkled within Alzheimer's disease plaques and the LILRB4 receptor on microglia cells (purple) activates them to clean up damaging plaques (blue) in the brain.

Researchers discover 'neutronic molecules'

Science Daily - 04/04/2024
Researchers have discovered 'neutronic' molecules, in which neutrons can be made to cling to quantum dots, held just by the strong force. The finding may lead to new tools for probing material properties at the quantum level and exploring new kinds of quantum information processing devices.

Researchers map how the brain regulates emotions

Science Daily - 04/04/2024
A new study is among the first of its kind to separate activity relating to emotion generation from emotion regulation in the human brain. The findings provide new insights that could help inform therapeutic treatments regarding mental health and drug addiction.

'Smart swarms' of tiny robots inspired by natural herd mentality

Science Daily - 04/04/2024
Researchers gave nanorobots a trait called adaptive time delay, which allows them to better work together.

Giant phage holds promise as treatment for lung infections

Science Daily - 03/04/2024
Researchers have discovered a new bacterial killer that can target common lung infection caused by Burkholderia bacteria that has exciting potential for biotechnological applications.

Machine learning enables viability of vertical-axis wind turbines

Science Daily - 03/04/2024
Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.

Plant-based plastic releases nine times less microplastics than conventional plastic

Science Daily - 03/04/2024
A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.

Drawing inspiration from plants: A metal-air paper battery for wearable devices

Science Daily - 03/04/2024
Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.
