Joro spiders well-poised to populate cities      (via sciencedaily.com)     Original source 

The Joro spider was first spotted stateside around 2013 and has since been spotted across Georgia and the Southeast. New research has found more clues as to why the spider has been so successful in its spread. The study found the invasive orb-weaving spider is surprisingly tolerant of the vibrations and noise common in urban landscapes. In this new study, researchers examined how Joro spiders can live next to busy roads, which are notably stressful environments for many animals.

Global deforestation leads to more mercury pollution      (via sciencedaily.com)     Original source 

Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.

How electron spectroscopy measures exciton 'holes'      (via sciencedaily.com)     Original source 

Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the bond between electrons and holes, they were able to gain a microscopic insight into charge transfer processes across a semiconductor interface.

Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets      (via sciencedaily.com)     Original source 

Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.

Alien invasion: Non-native earthworms threaten ecosystems      (via sciencedaily.com)     Original source 

Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.

Smart earrings can monitor a person's temperature      (via sciencedaily.com)     Original source 

Researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user's earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.

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 study finds 'sweet spot' for length of yarn-shaped supercapacitors      (via sciencedaily.com)     Original source 

Researchers have identified a 'sweet spot' at which the length of a threadlike energy storage technology called a 'yarn-shaped supercapacitor' (YSC) yields the highest and most efficient flow of energy per unit length.

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.

Apex predators not a quick fix for restoring ecosystems      (via sciencedaily.com)     Original source 

An experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return -- at least, not for a very long time. The study challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.

Microbial division of labor produces higher biofuel yields      (via sciencedaily.com)     Original source 

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.

How food availability could catalyze cultural transmission in wild orangutans      (via sciencedaily.com)     Original source 

The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?

Plant groupings in drylands support ecosystem resilience      (via sciencedaily.com)     Original source 

Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new article focused on the spatial patterns found in drylands offers important empirical evidence validating the models.

Scammed! Animals 'led by the nose' to leave plants alone      (via sciencedaily.com)     Original source 

Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.

Photonics-based wireless link breaks speed records for data transmission      (via sciencedaily.com)     Original source 

Researchers demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.
