Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production

According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton. from Top Environment News -- ScienceDaily https://ift.tt/sidaY4l

Hidden in plain sight: Windshield washer fluid is an unexpected emission source

Exhaust fumes probably come to mind when considering vehicle emissions, but they aren't the only source of pollutants released by a daily commute. Researchers report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. Notably, the levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. from Top Environment News -- ScienceDaily https://ift.tt/DhcR7y9

Researchers successfully induce primate oocytes in the lab

The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates. from Top Environment News -- ScienceDaily https://ift.tt/KOVlvgq

Twisting under the stroboscope -- Controlling crystal lattices of hybrid solar cell materials with terahertz light

To overcome global energy challenges and fight the looming environmental crisis, researchers around the world investigate new materials for converting sunlight into electricity.

Deep sea surveys detect over five thousand new species in future mining hotspot

There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first 'CCZ checklist' by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% - 92% of which are entirely new to science. from Top Environment News -- ScienceDaily https://ift.tt/ZDHvIR9

African smoke over the Amazon

Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin.

The evolution of honey bee brains

Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part of the insect brain involved in learning, memory and sensory integration) of 'primitive' sawflies and sophisticated honey bees. They found that three diverse, specialized Kenyon cell subtypes in honey bee brains appear to have evolved from a single, multifunctional Kenyon cell-subtype ancestor. In the future, this research could help us better understand the evolution of some of our own higher brain functions and behaviors. from Top Environment News -- ScienceDaily https://ift.tt/SbAGjVP

Gutless marine worms on a Mediterranean diet: Animals can synthesize phytosterols

Phytosterols are good for your health, but humans and other animals are not able to make them themselves, only plants can. To acquire phytosterols, humans are increasingly turning to supplements, green smoothies, or a Mediterranean diet with plenty of plant-based foods. Researchers have now discovered that tiny gutless worms from the Mediterranean can synthesize phytosterols on their own.
