When the boss burns out, the whole team loses energy, trust and performance‎

The well-being of a supervisor is reflected through supervisor-subordinate relationships in employee motivation and performance, and consequently, in the company's competitiveness. In his doctoral research at the University of Vaasa, Project Researcher Jussi Tanskanen demonstrates that an exhausted leader lacks the resources to maintain high-quality relationships with subordinates, leading to a collapse in employee dedication. This phenomenon is particularly pronounced in today's intensive work environment and remote work settings.

Free online lipid network aims to unite researchers and speed collaboration worldwide‎

Lipid research investigates the structure, function and metabolism of fats, covering their roles in industrial processes, the environment and health. Emerging research areas include nutrient regulation, cardiovascular health, lipidomics and biomarker discovery to understand, prevent or treat malfunction in diverse settings. An initiative led by Flinders University is building links between researchers, clinicians and industry professionals working across the diverse and rapidly evolving field of lipid science.

Predictably unpredictable: Building resilient crops for a changing world‎

An unusually mild winter followed by a wet spring made last year one of the worst in a decade for Pennsylvania soybean growers. It wasn't the soybeans that were the problem; it was the slugs. The pests survived the warm winter to lay a second round of eggs, and twice as many slugs hatched in the spring of 2024 as the year before. The slugs ate so many seedlings that some growers had to replant three times.

New research exposes the deadly exploitation of migrant fishers in poorly regulated waters‎

Isolated on a Taiwanese fishing vessel, eight days from the nearest landmass, 22-year-old Indonesian fisherman Sugiama was found dead in his bunk in 2019. His death followed an 18-hour shift and an assault the night before, when he was hit across the head for not working fast enough.

Envisioning just futures: Framework can make distributive justice explicit in global emission scenarios‎

Rising living costs, energy insecurity, widening inequality, and escalating climate impacts are fueling discussions on fairness and justice in climate policy. Yet, assumptions in global emission scenarios that determine who benefits and who bears the costs are often only made implicitly. A new IIASA-led study addresses this gap by offering a practical way to assess and design emission scenarios that explicitly account for distributive justice. The research is published in the journal npj Climate Action.

How hidden soil fungi 'steal' bacterial DNA to control the rain‎

Tiny organisms on the ground—bacteria and fungi—have a "superpower" that allows them to reach up into the atmosphere and pull down the rain, according to a recent study.

New 'molecular handle' uses common amino acid to build complex medicines‎

In a new study published in Nature Communications, a team of chemists has unveiled a radically simple way to attach a highly sought-after "molecular handle," known as the dichloromethyl group, onto complex compounds. Instead of relying on the aggressive, heavy-metal or radiation-heavy techniques of the past, the team used a common, naturally occurring amino acid called proline to gently choreograph the assembly.

Building 'green' protection for fragile enzymes‎

Enzymes are nature's tiny powerhouses, helping with everything from digesting food to making it quicker and safer to produce medicines, food and renewable fuels. While they can enhance chemical reactions, their fragile nature makes it difficult to use them in typical industrial processes.

Low-cost robotic chemistry system can be built and deployed in any lab‎

In a paper just out in Nature Synthesis, researchers led by Prof. Timothy Noël of the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences presented a breakthrough in autonomous laboratory systems for synthesis optimization. With an estimated cost of a mere $5,000, a versatile, modular design and the option for "human in the loop" analytics, RoboChem Flex caters to all synthesis laboratories, large or small. The paper provides all the information to build their own system.

A new fruit wash removes pesticides and extends shelf life‎

University of British Columbia researchers have developed a natural, biodegradable wash that removed up to 96% of pesticide residue from fruit and slowed browning and moisture loss. This could mean safer apples, grapes and other fruit that also stays fresh and crisp for days longer. With rising food prices and nearly half of all fresh produce wasted worldwide each year, finding a way to cut pesticide exposure and reduce spoilage could have a big impact. The findings are published in ACS Nano.
