Many plastic products are designed to be used only once, yet the material itself lasts for years. But a new strategy is addressing this problem by creating products that self-destruct on command, known as living plastics. These materials incorporate activatable, plastic-degrading microbes alongside the polymers. One team reporting in ACS Applied Polymer Materials used two bacterial strains that worked together and completely broke down the material within just six days, without making microplastics.
Why scientists are rethinking plastics Zhuojun Dai, a corresponding author on the paper, explains that “the realization that traditional plastics persist for centuries, while many applications, like packaging, are short-lived, led us to ask: Could we build degradation directly into the material’s life cycle?”
Many microbes can break long polymeric chains into smaller pieces using enzymes. Because plastics are polymers, these enzymes or the microbes that make them could be incorporated into living plastics.
In October 2024, the US Department of Energy (DOE) — under the Joe Biden administration — opened applications for funding to support the initial domestic deployment of Generation III+ small modular reactor (SMR) technologies, with up to USD800 million to go to two “first-mover” teams, with an additional USD100 million to address so-called gaps that have hindered plant deployments. According to the solicitation documentation, a Gen III+ SMR is defined as a nuclear fission reactor that uses light water as a coolant and low-enriched uranium fuel, with a single-unit net electrical power output of 50–350 MWe, that maximises factory fabrication approaches, and the same or improved safety, security, and environmental benefits compared with current large nuclear power plant designs.
The solicitation was re-issued by the DOE in March 2025 to better align with President Donald Trump’s agenda on unleashing American energy and AI dominance.
In December last year, the DOE selected Tennessee Valley Authority (TVA) and Holtec Government Services to each receive USD400 million in federal cost-shared funding to support early deployments of advanced light-water small modular reactors in the USA. TVA’s application was selected for funding to accelerate the deployment of a GE Vernova Hitachi BWRX-300 at its Clinch River site in East Tennessee. Holtec plans to deploy two SMR-300 reactors — named Pioneer 1 and 2 — at the Palisades Nuclear Generating Station site in Michigan.
Can we have higher yields and better taste? Using a natural extract from the fungus Pseudozyma aphidis, this method improves the firmness and natural sugar content of crops like tomatoes and melons while significantly boosting production. This discovery offers a practical path to meeting global food demands without compromising the health of the planet or produce quality. Furthermore, because the approach uses stable microbial secretions instead of live cultures, it ensures consistent and reliable performance across various agricultural environments and climates.
Researchers at the Hebrew University of Jerusalem have identified a natural, eco-friendly way to significantly increase agricultural yields while also improving the quality and taste of produce. The study, led by Professor Maggie Levy alongside researchers Anton Fennec and Neta Rotem, focuses on an extract derived from the yeast-like fungus Pseudozyma aphidis.
As the global population continues to grow, the demand for higher agricultural output has historically led to the heavy use of synthetic fertilizers and pesticides. These chemicals often contribute to soil and water pollution and increase greenhouse gas emissions. The new research, published in the journal Plant Physiology, suggests that beneficial micro-organisms can offer a sustainable alternative to these traditional agricultural inputs.
It is hypothesized that environmental contamination by per-and polyfluoroalkyl substances (PFAS) defines a separate planetary boundary and that this boundary has been exceeded. This hypothesis is tested by comparing the levels of four selected perfluoroalkyl acids (PFAAs) (i.e., perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid (PFHxS), and perfluorononanoic acid (PFNA)) in various global environmental media (i.e., rainwater, soils, and surface waters) with recently proposed guideline levels. On the basis of the four PFAAs considered, it is concluded that levels of PFOA and PFOS in rainwater often greatly exceed US Environmental Protection Agency (EPA) Lifetime Drinking Water Health Advisory levels and the sum of the aforementioned four PFAAs (Σ4 PFAS) in rainwater is often above Danish drinking water limit values also based on Σ4 PFAS; levels of PFOS in rainwater are often above Environmental Quality Standard for Inland European Union Surface Water; and atmospheric deposition also leads to global soils being ubiquitously contaminated and to be often above proposed Dutch guideline values. It is, therefore, concluded that the global spread of these four PFAAs in the atmosphere has led to the planetary boundary for chemical pollution being exceeded. Levels of PFAAs in atmospheric deposition are especially poorly reversible because of the high persistence of PFAAs and their ability to continuously cycle in the hydrosphere, including on sea spray aerosols emitted from the oceans. Because of the poor reversibility of environmental exposure to PFAS and their associated effects, it is vitally important that PFAS uses and emissions are rapidly restricted.
Researchers at the São Carlos Institute of Physics at the University of São Paulo (IFSC-USP) in Brazil, led by Paulo Augusto Raymundo-Pereira, have created biodegradable, “wearable” sensors for plants to monitor their health, including the presence of pesticides. The sensors are made from carbon ink and are screen-printed onto transparent cellulose acetate bioplastics.
The study was published in Biosensors and Bioelectronics: X. The World Economic Forum selected wearable sensor engineering as one of the top ten emerging technologies of 2023 for its potential to improve plant health and increase agricultural productivity.
However, most wearable devices today are made from nonrenewable plastic polymers derived from petroleum and have poor adhesion to uneven, wavy, and curved surfaces.
Breakthrough in brain medicine: a new way to deliver CBD!
Cannabidiol (CBD) has incredible potential to fight brain inflammation, but it has always faced a major roadblock: it struggles to dissolve and cross the blood-brain barrier. Researchers have just developed an ingenious solution using glucose-coated nanoparticles to get CBD exactly where it needs to go.
Here’s why it’s a game-changer: 🔬 Sneaky Delivery: The glucose coating helps the particles “hitch a ride” on the brain’s natural glucose transporters, successfully smuggling the CBD across the blood-brain barrier. 🎯 Smart Release: Once inside the brain, the nanoparticles target immune cells (microglia) and only release the CBD when they detect the chemical stress of active inflammation. 🐁 Promising Results: In mouse models of Parkinson’s disease and depression, this new delivery method drastically reduced inflammation, protected neurons, and improved behavioral recovery compared to standard CBD.
This targeted approach could be a massive step forward in treating chronic neuroinflammatory diseases! 🧬✨

Glucose-coated nanoparticles carry CBD across the blood-brain barrier, trigger release in inflamed tissue, and reduce neuroinflammatory signs in mice.
Not all pulmonary emboli are thrombotic. NTPE spans septic, tumor, fat, air, and iatrogenic causes, often mimicking PE but requiring different management. Recognizing key imaging clues + clinical context is critical for timely, lifesaving diagnosis.
Nonthrombotic pulmonary artery embolism (NTPE) involves occlusion of pulmonary arteries by nonthrombotic material, such as septic emboli, tumor cells, fat, air, or foreign substances. NTPE is less common than thrombotic pulmonary embolism (PE) and may be misdiagnosed as PE. Although the clinical manifestation mimics that of PE, NTPE has distinct pathophysiologic mechanisms that necessitate different management. Diagnosis requires a high index of clinical suspicion and knowledge of imaging findings. The authors provide an overview of the various causes of NTPE, including infectious, neoplastic, iatrogenic or exogenous, and miscellaneous entities, and highlight their key imaging findings. Early and accurate diagnosis is essential for appropriate management.

Weather forecasting is another aspect of modern life that artificial intelligence is transforming. Models like GraphCast, Pangu-Weather, and Fuxi are already better than traditional physics-based climate models at predicting some daily weather conditions. However, they are far from perfect. A new study published in the journal Science Advances reports that AI often fails to predict record-breaking extreme weather events.
Thanks to our changing climate, extremes such as record heat waves and windstorms are becoming more frequent. Accurate warnings are vital to help protect lives, property, and infrastructure. However, the unprecedented nature of these events poses a problem for AI.
To understand why, scientists pitted leading AI models against HRES (High Resolution Forecast), considered one of the world’s leading physics-based weather prediction systems. They first built a large database of record-breaking heat, cold, and wind events from 2018 and 2020. The researchers then checked the forecasts that HRES and the AI models had already made for those years to see which system got closest to the real-world outcomes.
From smartphone charging to hydrogen production, the fundamental principles of energy technology have been revealed. Korean researchers have, for the first time, identified how molecular structures change within the ultra-small space called the “electric double layer.” The study, published in the journal Nature Communications, opens a new path to simultaneously improve efficiency and performance in battery, hydrogen, and carbon-neutral technologies by reducing energy loss and selectively inducing desired reactions.
A research team led by Professor Hyungjun Kim from the Department of Chemistry, in collaboration with Professor Chang Hyuck Choi from POSTECH and Professor Seung-Jae Shin from UNIST, has identified structural phase transitions (phenomena in which the state or arrangement of matter changes) occurring within the electric double layer.
In particular, they revealed at the molecular level the cause of the phenomenon in which the pattern of electrical storage capacity (capacitance) changes from a camel shape to a bell shape depending on electrolyte concentration.
