New research delves into the intricate defense mechanisms of tomatoes against the notorious bacterial pathogen, Pseudomonas syringae pv. tomato (Pst). It's a classic tale of nature's arms race: as pathogens evolve to outsmart plant defenses, plants counter with more sophisticated immune responses.

People who own electric vehicles (EVs) are more likely to go a step further and add solar panels to their home, according to an analysis of a behavioral study. Conversely, the impact of owning solar panels also has a bearing on whether a homeowner buys an electric vehicle but not as strongly.

A study has found that green ammonia could be used to fulfill the fuel demands of over 60% of global shipping by targeting just the top 10 regional fuel ports. Researchers looked at the production costs of ammonia which are similar to very low sulphur fuels, and concluded that the fuel could be a viable option to help decarbonize international shipping by 2050.

As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.

A new study identifies, in mice, a critical communication pathway connecting the brain and the body's fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.

Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside the bacterium transports the substance to the 'elevator' and unloads its cargo there. The freight elevator transports it to the inside of the cell, in other words to another floor.

Mycelial fibers, the fibrous cells found in fruiting mushroom bodies, have gained momentum as a sustainable material for making faux-leather and packaging owing to their excellent formability. Recently, a team of researchers has found a simple way of obtaining mycelial fibers, called 'mycelial pulp,' from fruiting mushroom bodies and bleaching them using sunlight while keeping their mycelial structures intact.

Spin-orbit torque (SOT), an important phenomenon for developing ultrafast and low-power spintronic devices, can be enhanced through Berry phase monopole engineering at high temperatures. In a new study, the temperature dependence of the intrinsic spin Hall effect of TaSi2 was investigated. The results suggest that Berry phase monopole engineering is an effective strategy for achieving high-temperature SOT spintronic devices.

With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers have drawn inspiration from this natural wonder to develop a technological platform with similar capabilities for use in a variety of fields, including the military, medicine, robotics and sustainable energy.

Engineers have succeeded in implementing a stretchable organic solar cell by applying a newly developed polymer material that demonstrated the world's highest photovoltaic conversion efficiency (19%) while functioning even when stretched for more than 40% of its original state. This new conductive polymer has high photovoltaic properties that can be stretched like rubber. The newly developed polymer is expected to play a role as a power source for next-generation wearable electronic devices.
