Revolutionizing thermoelectric technology: Hourglass-shaped materials achieve a 360% efficiency boost      (via sciencedaily.com)     Original source 

A groundbreaking technology has been unveiled that improves the efficiency of thermoelectric materials, which are key in converting waste heat into electricity, by altering their geometry to resemble an hourglass. Unlike previous research that solely depended on the material properties of thermoelectric substances, this new approach is expected to have widespread applications in thermoelectric power generation.

Rethinking the dodo      (via sciencedaily.com)     Original source 

Researchers are setting out to challenge our misconceptions about the Dodo, one of the most well-known but poorly understood species of bird. Researchers have undertaken the most comprehensive review of the taxonomy of the Dodo and its closest relative, the Rodriguez Island Solitaire.

Blind cavefish have extraordinary taste buds      (via sciencedaily.com)     Original source 

A biologist studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. He looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.

Intelligent soft robotic clothing for automatic thermal adaptation in extreme heat      (via sciencedaily.com)     Original source 

As global warming intensifies, people increasingly suffer from extreme heat. For those working in a high-temperature environment indoors or outdoors, keeping thermally comfortable becomes particularly crucial. A team has now developed thermally-insulated and breathable soft robotic clothing that can automatically adapt to changing ambient temperatures, thereby helping to ensure worker safety in hot environments.

Lake Erie walleye growth is driven by parents' size, experience      (via sciencedaily.com)     Original source 

Parent size and the conditions in which actively spawning adults lived are the most influential factors affecting growth of Lake Erie walleye, a new study has found.

A belly full of jelly      (via sciencedaily.com)     Original source 

For a long time, scientists assumed that jellies (commonly known as jellyfish) were a dead-end food source for predatory fish. However, a team has now discovered that fish in Greenland waters do indeed feed on jellyfish. In two of the analyzed species, they even made up the majority of the food. The results suggest that the role of jellyfish as prey in marine food webs should be reconsidered, especially in regards to the fact that they could be profiting from climate change and spreading farther and farther north.

Ecologists put an insect group on century-old map of biodiversity      (via sciencedaily.com)     Original source 

The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used in various fields of biology.

Giant fossil seeds from Borneo record ancient plant migration      (via sciencedaily.com)     Original source 

Ancient fossil beans about the size of modern limes, and among the largest seeds in the fossil record, may provide new insight into the evolution of today's diverse Southeast Asian and Australian rainforests, according to researchers who identified the plants.

Pit-building venom mixers      (via sciencedaily.com)     Original source 

Researchers show that the adaptation of antlions to their ecological niche has also changed their venom. They compared the venom system of antlion and closely related green lacewing larvae. Antlions produce a much more complex venom from three different venom glands than lacewing larvae do. All the venom proteins identified come from the insects themselves, not from symbiotic bacteria. Some of the toxins are new and appear to be unique to antlions. Waiting for their victims in pitfall traps in the sand, antlions can use their venom to immobilize larger prey. The venom therefore plays an important ecological role in adapting to their barren habitat.

Rewriting the evolutionary history of critical components of the nervous system      (via sciencedaily.com)     Original source 

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.

Reduce, reuse, 're-fly-cle'      (via sciencedaily.com)     Original source 

Black soldier flies are now commercially used to consume organic waste -- but genetic modifications proposed by bioscientists could see the insects digesting a wider variety of refuse, while also creating raw ingredients for industry.

A new mechanism for shaping animal tissues      (via sciencedaily.com)     Original source 

A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams have now found a mechanism by which tissues can be 'programmed' to transition from a flat state to a three-dimensional shape.

New mechanism to cool buildings while saving energy      (via sciencedaily.com)     Original source 

The movement of radiant heat -- felt when a hot surface warms our bodies and homes -- between buildings and their surroundings at ground level makes buildings with less skyward-facing surfaces harder to cool. A research team has demonstrated a new passive cooling technology that coats walls and windows with materials that can better manage heat movement between buildings and their surroundings at ground level. Findings could reduce the reliance on air conditioning and provide a more environmentally friendly, low-cost and scalable option for low-income communities with limited or no access to cooling and heating systems.

Researchers make breakthrough in understanding species abundance      (via sciencedaily.com)     Original source 

The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.

New technology uses light to engrave erasable 3D images      (via sciencedaily.com)     Original source 

Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
