University of Toronto researchers have designed a new composite material that is both very light and extremely strong—even at temperatures up to 500 Celsius.
The material, which is described in a paper published in Nature Communications, is made of various metallic alloys and nanoscale precipitates, and has a structure that mimics that of reinforced concrete—but on a microscopic scale.
These properties could make it extremely useful in aerospace and other high-performance industries.
Artificial light-type plant factories are an emerging agricultural innovation that enables crops to be grown year-round in precisely controlled environments. By adjusting factors such as light, temperature, humidity, carbon dioxide concentration, and nutrient delivery, these facilities can produce stable yields independent of climate conditions. They offer a promising way to reduce pesticide use and minimize the impacts of climate change.
However, legumes like edamame have long been considered difficult to cultivate in such settings because of their long growth periods, short storage periods, complex flowering, and pod-setting processes.
Against this backdrop, the research group, led by Professor Toshio Sano from the Faculty of Bioscience and Applied Chemistry, Hosei University, Japan, and Associate Professor Wataru Yamori of the Graduate School of Agricultural and Life Sciences, The University of Tokyo, Japan, had previously gained attention for successfully cultivating tomatoes under LED lighting in a plant factory.
A solution to a tricky groundwater riddle from Australia: Researchers at TU Wien have developed numerical models to simulate the movement of fluids in porous materials.
Things are complicated along the Murray–Darling River in southern Australia. Agricultural irrigation washes salt out of the upper soil layers, and this salt eventually ends up in the river. To prevent the river’s salt concentration from rising too much, part of the salty water is diverted into special basins.
Some of these basins are designed to let the salty water evaporate, others to slowly release it in a controlled manner in the underground. That keeps salt temporarily out of the river and allows better management of the river’s water—but it increases the salinity in the ground. How can we calculate how this saltwater spreads underground and what its long-term effects will be?
It’s bound to happen at a summer picnic, a peaceful walk in the woods or simply sitting in your backyard… a mosquito targets your blood for its next meal. You’ve been bitten. But how do mosquitoes find you?
Among several methods used to locate new hosts for blood-sucking, mosquitoes feature a keen ability to detect carbon dioxide. As we breathe out, we emit CO2 into the air around us, which mosquitoes can sense. But how?
Scientists have been aware of the mosquito’s ability to detect our carbon dioxide expirations but the intricate underlying physiological structures enabling these capabilities have largely remained unclear.
Questions to inspire discussion.
💰 Q: What would California’s wealth tax cost super voting shareholders like Larry Page and Sergey Brin? A: The tax multiplies voting ownership percentage by market cap to value super voting shares, resulting in a punitive tax rate of up to 50% on net worth for founders with control premiums.
🏃 Q: How much wealth could leave California if the asset seizure tax passes? A: An estimated half a trillion dollars in net worth could exit the state, creating severe budget implications for California’s social programs and general budget.
📊 Q: What should entrepreneurs do to prepare for potential wealth taxes on unrealized gains? A: Maintain a liquid safety net to cover tax bills on unrealized gains, though this is impossible to plan for if stock values later decline and bankrupt the company.

🤖 Q: Which company will become the first with more robots than humans? A: Amazon is predicted to become the first company with more robots than humans driving its bottom line by 2026 as they deploy robots while keeping human hiring flat.
Glioblastoma is one of the deadliest brain cancers, with a median survival rate of just 15 months. Despite surgery and chemotherapy, more than 1250 clinical trials over the past 20 years have struggled to improve survival rates.
Published in Nature Communications, the study shows that a small population of drug-tolerant cells known as “persister cells” rewires its metabolism to survive chemotherapy, using an unexpected ally as an invisibility cloak: a fertility gene called PRDM9.
The authors identified that chemotherapy-induced PRDM9 upregulation promotes metabolic rewiring in glioblastoma stem cells, leading to chemotherapy tolerance. Mechanistically, PRDM9-dependent H3K4me3 at cholesterol biosynthesis genes enhances cholesterol biosynthesis, which persister cells rely on to maintain homeostasis under chemotherapy-induced oxidative stress and lipid peroxidation.
PRDM9 inhibition, combined with chemotherapy, results in strong anti-cancer efficacy in preclinical glioblastoma models, significantly enhancing the magnitude and duration of the antitumor response by eliminating persisters.
Previously, PRDM9 was only known as a fertility gene, active in reproductive cells at the very start of egg and sperm formation, long before fertilisation.
The researchers are now working with Australian biotech company Syntara to develop PRDM9 inhibitors for further testing in animal models, with the hope to eventually progress to human studies.
