Warmer wetter climate predicted to bring societal and ecological impact to the Tibetan Plateau      (via sciencedaily.com)     Original source 

According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.

Investigating the origin of circatidal rhythms in freshwater snails      (via sciencedaily.com)     Original source 

While most organisms have biological clocks synchronized with the day-night cycle (circadian rhythms), marine animals in tidal areas have also developed circatidal rhythms to align with the tidal cycle. Comparing the activity and genetic expression of snails from tidal and non-tidal areas, researchers demonstrate that circatidal rhythms develop as snails adapt to tidal environments. These findings highlight the flexibility of biological clocks, enabling organisms to adjust their rhythms according to the environment.

Entomologist sheds light on 250-year-old mystery of the German cockroach      (via sciencedaily.com)     Original source 

Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.

Controlling water, transforming greenhouse gases      (via sciencedaily.com)     Original source 

Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.

Observing mammalian cells with superfast soft X-rays      (via sciencedaily.com)     Original source 

Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.

Breakthrough discovery uses engineered surfaces to shed heat      (via sciencedaily.com)     Original source 

Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface. The temperature at which this phenomenon, called the Leidenfrost effect, occurs is predictable, usually happening above 230 degrees Celsius. A team has now discovered a method to create the aquatic levitation at a much lower temperature.

Innovative material for sustainable building      (via sciencedaily.com)     Original source 

Researchers introduce a polymer-based material with unique properties. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future.

Key role of plant-bacteria communication for the assembly of a healthy plant microbiome supporting sustainable plant nutrition      (via sciencedaily.com)     Original source 

In an interdisciplinary study, researchers discovered that symbiotic bacteria communicate with legume plants through specific molecules and that this communication influences which bacteria grow near the plant roots. The findings provide insights into how plants and soil bacteria form beneficial partnerships for nutrient uptake and resilience. These results are a step towards understanding how communication between plants and soil bacteria can lead to specific beneficial associations providing plants with nutrients.

New approach to Epstein-Barr virus and resulting diseases      (via sciencedaily.com)     Original source 

The Epstein-Barr virus can cause a spectrum of diseases, including a range of cancers. Emerging data now show that inhibition of a specific metabolic pathway in infected cells can diminish latent infection and therefore the risk of downstream disease.

Psychedelic drug-induced hyperconnectivity in the brain helps clarify altered subjective experiences      (via sciencedaily.com)     Original source 

A new study shows that the use of psilocybin, a compound found in the widely known 'magic mushrooms,' initiates a pattern of hyperconnectivity in the brain linked to the ego-modifying effects and feelings of oceanic boundlessness. The findings help explain the so-called mystical experiences people report during the use of psychedelics and are pertinent to the psychotherapeutic applications of psychedelic drugs to treat psychiatric disorders such as depression.

Birdsong and human voice built from same genetic blueprint      (via sciencedaily.com)     Original source 

Humans have been long fascinated by bird song and the cacophony of other avian sounds -- from coos and honks to quacks and peeps. But little is known about how the unique vocal organ of birds -- the syrinx -- varies from species to species or its deeper evolutionary origins. A trio of recent studies is changing that. The studies include high-resolution anatomical scans of syrinxes from hummingbirds and ostriches -- the world's smallest and largest bird species -- and the discovery that the syrinx and larynx, the vocal organ of reptiles and mammals, including humans, share the same developmental programming.

Novel approach to interrogate tissue-specific protein-protein interactions      (via sciencedaily.com)     Original source 

Multicellular organisms, like animals and plants, have complex cells with diverse functions. This complexity arises from the need for cells to produce distinct proteins that interact with each other. This interaction is crucial for cells to carry out their specific tasks and to form complex molecular machinery. However, our current understanding of such protein-protein interactions often lacks cellular contexts because they were usually studied in an in vitro system or in cells isolated from their tissue environment. Effective methods to investigate protein-protein interactions in a tissue-specific manner are largely missing.
