Is magnesium the sleeping potion that enables sandhoppers to survive cold winters?      (via sciencedaily.com)     Original source 

A new study has shown for the first time that when sandhoppers want to enter a period of deep sleep each winter they have the means through which to increase the magnesium levels in their bodies -- in some instances more than doubling them. Essentially acting as a natural narcotic, the magnesium puts the sandhopper into a torpid state and this enforced rest means that the creatures can stay hidden in burrows up to 30cm beneath the beach surface, to some extent buffered from wintry conditions.

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.

Early Homo sapiens facilitated the establishment of the Bonelli's eagle in the Mediterranean 50,000 years ago      (via sciencedaily.com)     Original source 

Scientists have unraveled the ancestral history of one of the most iconic birds of prey in the current Iberian fauna: the Bonelli's eagle (Aquila fasciata). The study combines evidence from several disciplines, including palaeontology, genetics and ecology, to answer questions about when and why the Bonelli's eagle, a species primarily found in tropical and subtropical areas, colonized the Mediterranean Basin.

Tiny New Zealand bird delivers a lesson in birdsong evolution      (via sciencedaily.com)     Original source 

Scientists are rethinking the evolution of vocal learning in birds. New Zealand's smallest bird, the rifleman or titipounamu, may have a rudimentary version of the talent possessed by parrots, hummingbirds and songbirds.

Fasting primes the immune system's natural killer cells to better fight cancer, new study in mice finds      (via sciencedaily.com)     Original source 

A team of researchers has shown for the first time that fasting can reprogram the metabolism of natural killer cells, helping them to survive in the harsh environment in and around tumors, while also improving their cancer-fighting ability.

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.

Sweaty cattle may boost food security in a warming world      (via sciencedaily.com)     Original source 

Climate change is making it more difficult to raise cattle -- growth and reproduction are affected by heat -- so it's critical to breed cattle better adapted to a hotter and longer summer. A new study shows it's possible to identify the genes within breeds of cattle that would lead to the sweatiest, heat-tolerant offspring.

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.

Only one in 20 therapies tested in animals reach approval for human use      (via sciencedaily.com)     Original source 

An analysis of reviews of translational biomedical research reveals that just 5% of therapies tested in animals reach regulatory approval for human use. The umbrella review summarizes other systematic reviews and provides high level evidence that while the rate of translation to human studies is 50%, there is steep drop off before final approval.

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.

Outdoor recreation noise affects wildlife behavior and habitat use, study finds      (via sciencedaily.com)     Original source 

We may go to the woods seeking peace and quiet, but are we taking our noise with us? A recent study indicates that the answer is yes -- and that this noise can trigger a fear response, as if escaping from predators. This new science calls into question whether otherwise high-quality habitat truly provides refugia for wildlife when recreationists are present and underscores the challenges land managers face in balancing outdoor recreational opportunities with wildlife conservation.
