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.

Friend or foe? Ancient partnership between moss and fungi      (via sciencedaily.com)     Original source 

Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.

Replacing animal-based foods with alternative proteins would unlock land for carbon removal      (via sciencedaily.com)     Original source 

Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.

New study sheds new light on forests' role in climate and water cycle      (via sciencedaily.com)     Original source 

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.

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.

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.

Rare 3D fossils show that some early trees had forms unlike any you've ever seen      (via sciencedaily.com)     Original source 

In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

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.

Tidal landscapes a greater carbon sink than previously thought      (via sciencedaily.com)     Original source 

Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.

Increased temperature difference between day and night can affect all life on earth      (via sciencedaily.com)     Original source 

Researchers have discovered a change in what scientists already knew about global warming dynamics. It had been widely accepted since the 1950s that global temperature rises were not consistent throughout the day and night, with greater nighttime warming being observed. However, the recent study reveals a shift in dynamics: with greater daytime warming taking place since the 1990s. This shift means that the temperature difference between day and night is widening, potentially affecting all life on Earth.

Climate change threatens older elephants most, jeopardizing African elephants' future      (via sciencedaily.com)     Original source 

A collaborative team of researchers has conducted first-of-its kind research into how global climate change affects African elephants. The work shows that older elephants will have markedly decreased chances of survival, which will not only drastically reduce the species' overall ability to weather the changing climate but will send ripple effects throughout the surrounding landscape. The team has also modeled possible mitigation scenarios.
