Discovery of vast sex differences in cellular activity has major implications for disease treatment      (via sciencedaily.com)     Original source 

The study reveals vast differences in gene activity within the mitochondria of males compared to females. This is the first study to test effects of all 37 genes in the mitochondrial genome -- genes that copepods and humans share. The study found that males demonstrate more activity across all protein-coding mitochondrial genes than females. Although the study looks at tiny marine organisms called copepods, the findings have weighty implications for human medicine.

Robots face the future      (via sciencedaily.com)     Original source 

Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.

3D-printed chip sensor detects foodborne pathogens for safer products      (via sciencedaily.com)     Original source 

Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.

How cells boost gene expression      (via sciencedaily.com)     Original source 

The function of non-coding RNA in the cell has long been a mystery to researchers. Unlike coding RNA, non-coding RNA does not produce proteins -- yet it exists in large quantities. A research team has now discovered an important function of antisense RNA (asRNA): the researchers found that asRNA acts as a 'superhighway' in cell transport and thus accelerates gene expression.

Star clusters observed within a galaxy in the early Universe      (via sciencedaily.com)     Original source 

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to understanding it. New insights about young galaxies during the Epoch of Reionization have been revealed. Observations with the James Webb Space Telescope (JWST) of the galaxy Cosmic Gems arc (SPT0615-JD) have confirmed that the light of the galaxy was emitted 460 million years after the big bang. What makes this galaxy unique is that it is magnified through an effect called gravitational lensing, which has not been observed in other galaxies formed during that age.
