Synthesis gas and battery power from sunlight energy      (via sciencedaily.com) 

Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.

Jellyfish size might influence their nutritional value      (via sciencedaily.com) 

Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.

'Green' hydrogen: How photoelectrochemical water splitting may become competitive      (via sciencedaily.com) 

Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical and pharmaceutical industries. The energy payback time of photoelectrochemical 'green' hydrogen production can be reduced dramatically, the study shows.

Muscle health depends on lipid synthesis      (via sciencedaily.com)     Original source 

Muscle degeneration, the most prevalent cause of frailty in hereditary diseases and aging, could be caused by a deficiency in one key enzyme in a lipid biosynthesis pathway. Researchers now characterize how the enzyme PCYT2 affects muscle health in disease and aging in laboratory mouse models.

An elegant new orchid hiding in plain sight      (via sciencedaily.com) 

It is extremely rare for a new plant species to be discovered in Japan, a nation where flora has been extensively studied and documented. Nevertheless, botanists recently uncovered a stunning new species of orchid whose rosy pink petals bear a striking resemblance to glasswork. Interestingly, it can be found in familiar environments such as lawns and parks, and even in private gardens and on balconies. This research suggests that other new species may be hiding in common places.

Discovery of an unexpected function of blood immune cells: Their ability to proliferate      (via sciencedaily.com) 

The ability of a cell to divide, to proliferate, is essential for life and gives rise to the formation of complex organisms from a single cell. It also allows the replacement of used cells from a limited number of 'stem' cells, which then proliferate and specialize. In cancer, however, cell proliferation is no longer controlled and becomes chaotic. Researchers have discovered that, in a healthy individual, certain blood immune cells, the monocytes, also have this ability to proliferate, with the aim to replace tissue macrophages, which are essential for the proper functioning of our body.

An extra X chromosome-linked gene may explain decreased viral infection severity in females      (via sciencedaily.com) 

It has long been known that viral infections can be more severe in males than females, but the question as to why has remained a mystery -- until possibly now. Researchers have found that female mouse and human Natural Killer cells have an extra copy of an X chromosome-linked gene called UTX. UTX acts as an epigenetic regulator to boost NK cell anti-viral function, while repressing NK cell numbers.

Loss of Menin helps drive the aging process, and dietary supplement can reverse it in mice      (via sciencedaily.com) 

Decline in the hypothalamic Menin may play a key role in aging, according to a new study. The findings reveal a previously unknown driver of physiological aging, and suggest that supplementation with a simple amino acid may mitigate some age-related changes.

Compressive stress shapes the symmetry of Arabidopsis root vascular tissue      (via sciencedaily.com) 

A cytokinin-mediated, proliferation-based mechanism is involved in the generation and maintenance of cell-type specific tissue boundaries during vascular development in Arabidopsis roots. Specifically, the HANABA-TARANU transcription factor forms a feed-forward loop to cytokinin signaling, which in turn regulates the position and frequency of cell proliferation of proto-vascular cells such that mechanical stress of the surrounding tissues guides growth in an apical-oriented manor, maintaining cell patterning throughout the tissue section.

Where the HI-Virus sleeps in the brain      (via sciencedaily.com) 

The human immunodeficiency virus HIV-1 is able to infect various tissues in humans. Once inside the cells, the virus integrates its genome into the cellular genome and establishes persistent infections. The role of the structure and organization of the host genome in HIV-1 infection is not well understood. Using a cell culture model based on brain immune microglia cells, an international research team has now defined the insertion patterns of HIV-1 in the genome of microglia cells.

Cellular waste removal differs according to cell type      (via sciencedaily.com) 

'Miniature shredders' are at work in each cell, disassembling and recycling cell components that are defective or no longer required. The exact structure of these shredders differs from cell type to cell type, a study now shows. For example, cancer cells have a special variant that can supply them particularly effectively with building blocks for their energy metabolism.
