Computable species descriptions: Scientists develop a new computer language to model organismal traits      (via sciencedaily.com)     Original source 

Understanding organismal traits and learning how they evolve and adapt to different environments is crucial for biologists and the battle against biodiversity loss. To be truly efficient, however, the researchers need to use huge amounts of data, including physical traits and DNA. Furthermore, those different data types need to be accurately linked to each other, so that computers and next-age AI technology can correctly process it. Currently, this process of accurate linking is extremely difficult and largely inefficient. To solve this problem, researchers created a brand new computer language called Phenoscript.

Previously uncharacterized parasite uncovered in fish worldwide      (via sciencedaily.com)     Original source 

Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.

Quantum entanglement measures Earth rotation      (via sciencedaily.com)     Original source 

Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.

A new weapon in the battle against antibiotic resistance: Temperature      (via sciencedaily.com)     Original source 

Scientists have shown in laboratory experiments that an increase in temperature from 37 to 40 degrees Celsius increased the resistance rate for two antimicrobials, while for a third antimicrobial, the higher temperature reduced the resistance rate. If these results can be replicated in human patients, fever control could be a new way to mitigate the emergence of antibiotic resistance.

The genetic 'switches' of bone growth      (via sciencedaily.com)     Original source 

In mammals, only 3% of the genome consists of coding genes which, when transcribed into proteins, ensure the biological functions of the organism and the in-utero development of future individuals. But genes do not function alone. They are controlled by other sequences in the genome, called enhancers, which, like switches, activate or deactivate them as required. A team has now identified and located 2700 enhancers -- among millions of non-coding genetic sequences -- that precisely regulate the genes responsible for bone growth. This discovery sheds light on one of the major factors influencing the size of individuals in adulthood, and explains why their failure could be the cause of certain bone malformations.

Infectious H5N1 influenza virus in raw milk rapidly declines with heat treatment      (via sciencedaily.com)     Original source 

The amount of infectious H5N1 influenza viruses in raw milk rapidly declined with heat treatment in laboratory research. However, small, detectable amounts of infectious virus remained in raw milk samples with high virus levels when treated at 72 degrees Celsius (161.6 degrees Fahrenheit) for 15 seconds -- one of the standard pasteurization methods used by the dairy industry. The authors of the study stress, however, that their findings reflect experimental conditions in a laboratory setting and are not identical to large-scale industrial pasteurization processes for raw milk.

A conservation market could incentivize global ocean protection      (via sciencedaily.com)     Original source 

Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.

Can engineered plants help make baby formula as nutritious as breast milk?      (via sciencedaily.com)     Original source 

New research may help close the nutrition gap between infant formula and human breast milk. The study shows how plants can be programmed to produce a diverse array of beneficial sugars found in human breast milk. The findings could lead to healthier and more affordable formula for babies, or more nutritious non-dairy plant milk for adults.

Modifying genomes of tardigrades to unravel their secrets      (via sciencedaily.com)     Original source 

Some species of tardigrades are highly and unusually resilient to various extreme conditions fatal to most other forms of life. The genetic basis for these exceptional abilities remains elusive. Researchers have now successfully edited genes using the CRISPR technique in a highly resilient tardigrade species previously impossible to study with genome-editing tools. The successful delivery of CRISPR to an asexual tardigrade species directly produces gene-edited offspring. The design and editing of specific tardigrade genes allow researchers to investigate which are responsible for tardigrade resilience and how such resilience can work.

Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate      (via sciencedaily.com)     Original source 

The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.
