Micro-Lisa! Making a mark with novel nano-scale laser writing      (via sciencedaily.com)     Original source 

High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.

Bees need food up to a month earlier than provided by recommended pollinator plants      (via sciencedaily.com)     Original source 

Plant species which are recommended as 'pollinator friendly' in Europe begin flowering up to a month too late for bees, resulting in low colony survival and low production of queens. This research has quantified the decline in colony survival and queen production due to a shortage of early season food. Enhancing existing hedgerows with early blooming species has the potential to increase the probability that a bee colony survives from 35% to 100%.

Rays were more diverse 150 million years ago than previously thought      (via sciencedaily.com)     Original source 

Scientists have explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity -- including a new ray species. This study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.

N-channel diamond field-effect transistor      (via sciencedaily.com)     Original source 

A research team has developed an n-channel diamond MOSFET (metal-oxide-semiconductor field-effect transistor). The developed n-channel diamond MOSFET provides a key step toward CMOS (complementary metal-oxide-semiconductor: one of the most popular technologies in the computer chip) integrated circuits for harsh-environment- applications as well as the development of diamond power electronics.

Species diversity promotes ecosystem stability      (via sciencedaily.com)     Original source 

What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? A new study suggests an answer to this question that has been a subject of debate among ecologists for half a century.

Cleaning up environmental contaminants with quantum dot technology      (via sciencedaily.com)     Original source 

The 2023 Nobel Prize in Chemistry was focused on quantum dots -- objects so tiny, they're controlled by the strange rules of quantum physics. Quantum dots used in electronics are often toxic, but their nontoxic counterparts are being explored for uses in medicine and in the environment, including water decontamination. One team of researchers has specially designed carbon- and sulfur-based dots for these environmental applications.

Recyclable reagent and sunlight convert carbon monoxide into methanol      (via sciencedaily.com)     Original source 

Scientists have demonstrated the selective conversion of carbon dioxide (CO2) into methanol using a cascade reaction strategy. The two-part process is powered by sunlight, occurs at room temperature and at ambient pressure, and employs a recyclable organic reagent that's similar to a catalyst found in natural photosynthesis.

Toxic metal particles can be present in cannabis vapes even before the first use, study finds      (via sciencedaily.com)     Original source 

Though vapes have been heralded as a 'safer' way to consume either nicotine or cannabis, they present their own suite of risks that are being revealed through increasing regulation. Now, scientists have discovered that nano-sized toxic metal particles can be present in cannabis vaping liquids even before any heating occurs, and the effect is worse in illicit products.

Molecular crystal motors move like microbes when exposed to light      (via sciencedaily.com)     Original source 

At first glance, Rabih Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're made from crystallized molecules that perform coordinated movements when exposed to light. With continued development, these tiny machines could be used as drug-delivery robots or engineered into arrays that direct the flow of water around submarines.
