Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years      (via sciencedaily.com)     Original source 

A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.

How to use AI for discovery -- without leading science astray      (via sciencedaily.com)     Original source 

In the same way that chatbots sometimes 'hallucinate,' or make things up, machine learning models designed for scientific applications can sometimes present misleading or downright false results. Researchers now present a new statistical technique for safely using AI predictions to test scientific hypotheses.

Liquid metals shake up century-old chemical engineering processes      (via sciencedaily.com)     Original source 

Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.

Yeast with an over half synthetic genome is created in the lab      (via sciencedaily.com)     Original source 

Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.

Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks      (via sciencedaily.com)     Original source 

Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.

Infection with common cat-borne parasite associated with frailty in older adults      (via sciencedaily.com)     Original source 

A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gondii has previously been associated with risk-taking behavior and mental illness.

Charged 'molecular beasts' the basis for new compounds      (via sciencedaily.com)     Original source 

Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules.

Large herbivores such as elephants, bison and moose contribute to tree diversity      (via sciencedaily.com)     Original source 

Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.

New secrets about cat evolution revealed      (via sciencedaily.com)     Original source 

By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.

Research outlines how sex differences have evolved      (via sciencedaily.com)     Original source 

Researchers have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.

Self-powered microbial fuel cell biosensor for monitoring organic freshwater pollution      (via sciencedaily.com)     Original source 

Biodegradable waste from plant and animal sources released into freshwater ecosystems is a significant environmental concern. Nonetheless, current methods for assessing water quality seem more or less impractical due to their complexity and high costs. In a promising development, a team of researchers has successfully constructed a self-sustaining and buoyant biosensor using inexpensive carbon-based materials for monitoring water quality at the inlets of freshwater lakes and rivers.
