The wild can be a 'death trap' for rescued animals‎

A new study has found that the wild can be a "death trap" for animals that are released from captivity after previously being rescued. The research, published in the journal Global Ecology and Conservation, involved Anglia Ruskin University primatologist Professor Anna Nekaris OBE and colleagues from the NGO Plumploris e.V. and the University of Western Australia, who studied the outcome of Bengal slow lorises (Nycticebus bengalensis) released in Bangladesh.

Nano-cage removes up to 98% of PFAS in tap water tests‎

Contamination of ground, surface and drinking water by perfluoroalkyl and polyfluoroalkyl substances (PFAS) affects millions of people worldwide. A promising new method developed by Flinders University scientists paves the way to help remove the most difficult-to-capture variants of these persistent pollutants from water.

A world first at the microscopic scale: Metamaterials that can shrink and expand on their own‎

Leiden physicists Daniela Kraft and Julio Melio have created soft structures that can take on different shapes without any external drive in their lab. They present their research on microscale metamaterials in Nature—a breakthrough that opens the door to smart, reconfigurable materials and microscopic robots.

Hidden architecture inside cellular droplets reveals new targets for cancer and neurodegeneration‎

Cells rely on biomolecular condensates to coordinate essential biological processes without surrounding membranes. These droplet-like dynamic assemblies control the way in which DNA is turned into proteins, help clear cellular waste to prevent toxicity and disease, and can even suppress cancerous tumors. Because they behave like liquids, able to merge, flow and rapidly exchange their contents, scientists had long assumed condensates lacked internal organization and functioned as a simple liquid.

'Lock-and-key' chemistry keeps cancer drugs inactive until they reach tumor sites‎

Many therapeutic molecules used in cancer treatments are highly toxic, often harming healthy tissues and causing significant side effects. This creates a critical need for strategies that localize their toxic activity to tumors. What if cancer drugs could stay dormant until they reach cancer cells? A new study by Syracuse University researchers demonstrates a promising chemistry-based strategy that could do just that.

Why plants may bloom earlier: Tiny dew droplets are triggering early flowering in plants‎

Plants around the world are flowering earlier in the year, a trend attributed to climate change. But there could be another hitherto hidden trigger. Scientists led by researchers at the Chinese Academy of Sciences suggest a cause may be morning dew drops, as explained in a paper in the journal Proceedings of the National Academy of Sciences.

Ultrasound-activated molecules show potential for killing antibiotic-resistant bacteria‎

Researchers from the Indian Institute of Technology Gandhinagar (IITGN) have recently demonstrated the feasibility of using estrone-linked BODIPYs sonosensitizers for antimicrobial sonodynamic therapy (SDT). Their initial findings are published in Chemistry—An Asian Journal.

A robust new telecom qubit identified in silicon‎

Quantum technologies are anticipated to transform computing, communication, and sensing by harnessing the unusual behavior of matter at the atomic scale. Translating quantum's promise into practical devices will require physical systems that have desirable quantum properties and can be easily manufactured. Silicon, the material behind today's computer chips, is highly attractive as a platform because it plays to the strengths of the trillion-dollar semiconductor industry that has already been built. Identifying quantum building blocks—qubits—in silicon is, therefore, an important frontier research area.

Scientists discover 10 new species of Hawaiian moths‎

University of Hawaiʻi at Mānoa researchers identified 10 new species and seven new groups (genera) of Hawaiian leaf-roller moths. While new species are frequently discovered, the description of a new genus of insects is a much rarer event; seven groups at once is almost unheard of. Discovered by College of Tropical Agriculture and Human Resilience (CTAHR) graduate student Kyhl Austin and Professor Daniel Rubinoff, this research highlights how much Native Hawaiian biodiversity remains a mystery.

Alcohol-free drinks uncover alcohol pricing secrets‎

Alcohol pricing is often analyzed using sophisticated computer models to understand how policy changes, such as adjustments to excise, might affect drinking behavior and public health. But the growth of no and low alcohol drinks that closely resemble well-known beer, wine and spirits products—"nolo" look-alikes—means alcohol companies themselves now provide useful real world points of comparison for alcohol pricing.
