Nature is particularly beneficial for people on lower income      (via sciencedaily.com)     Original source 

Data from a representative sample of the Austrian population suggests that the relationship between nature contact and well-being is consistently stronger for people on lower than higher incomes. However, this pattern was only found when people actively visited nature and not when they merely lived near greenspaces. Findings suggest the availability, accessibility and use of green and blue spaces can play an important role in reducing income-related health inequalities.

Inexpensive, carbon-neutral biofuels are finally possible      (via sciencedaily.com)     Original source 

When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.

New approach for fast and cost-effective pathogen detection      (via sciencedaily.com)     Original source 

The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.

Japan's electric vehicle transition by 2035 may be insufficient to combat the climate crisis, but there are solutions      (via sciencedaily.com)     Original source 

Researchers report that Japan's policy of banning the sale of new gas vehicles by 2035 may be insufficient to reduce the country's CO2 emissions. The team's analysis showed that to effectively reach their climate goals, Japan must also implement policies that extend vehicle lifetime, implement more renewable energy into its energy sector, and decarbonize the manufacturing process of vehicles.

New approach to tackling bacterial infections identified      (via sciencedaily.com)     Original source 

Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.

Researchers reveal elusive bottleneck holding back global effort to convert carbon dioxide waste into usable products      (via sciencedaily.com)     Original source 

Think of it as recycling on the nanoscale: a tantalizing electrochemical process that can harvest carbon before it becomes air pollution and restructure it into the components of everyday products. The drive to capture airborne carbon dioxide from industrial waste and make it into fuel and plastics is gaining momentum after a team of researchers uncovered precisely how the process works and where it bogs down.

Researchers discover key to molecular mystery of how plants respond to changing conditions      (via sciencedaily.com)     Original source 

A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.

Complex tree canopies help forests recover from moderate-severity disturbances      (via sciencedaily.com)     Original source 

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.

Mystery of novel clove-like off-flavor in orange juice solved      (via sciencedaily.com)     Original source 

A research team has solved the mystery of a novel clove-like off-flavor in orange juice, the cause of which was previously unknown. The study proves for the first time that the undesirable flavor note is due to the odorant 5-vinylguaiacol. As the results of the study show, the substance is mainly produced during the pasteurization process when residues of a cleaning agent react with a natural orange juice component under the influence of heat.

Improving fuel cell durability with fatigue-resistant membranes      (via sciencedaily.com)     Original source 

In hydrogen fuel cells, electrolyte membranes frequently undergo deformation and develop cracks during operation. A research team has recently introduced a fatigue-resistant polymer electrolyte membrane for hydrogen fuel cells, employing an interpenetrating network of Nafion (a plastic electrolyte) and perfluoropolyether (a rubbery polymer). This innovation will not only improve fuel cell vehicles but also promises advancements in diverse technologies beyond transportation, spanning applications from drones to desalination filters and backup power sources.
