	Researchers warn continuous glucose monitors can overestimate blood sugar levels Continuous Glucose Monitors (CGMs) are growing in popularity but new research, published in The American Journal of Clinical Nutrition, from the University of Bath, suggests they may not be as accurate as many believe. Originally designed to help people living with diabetes manage their blood sugar, these devices are now being used by the health-conscious to track how different foods affect their glucose levels.
	Engineers create first flat telescope lens that can capture color while detecting light from faraway stars For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be, the bulkier and heavier they become.
	Epigenetic echoes: Violence can leave genetic marks on future generations In 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence. Four decades later, rebels used the memory of the massacre to help inspire the toppling of the Assad family that had overseen the operation.
	Scientists match Earth's ice age cycles with orbital shifts Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests the onset of the next ice age could be expected in 10,000 years' time.
	Brewing tea reduces toxic heavy metals in drinking water, study finds Good news for tea lovers: That daily brew might be purifying the water, too.
	How to see rare 'planetary parade' in the sky tonight The seven other planets in our solar system will line up in the night sky on Friday evening for a rare alignment called a "planetary parade" that will not happen again until 2040.
	Mega-iceberg from Antarctica is headed toward South Georgia—here's what could happen It is no strange sight to see icebergs break off of the Antarctic ice cap and drift away, like the gigantic sheet of ice that is currently heading for the island of South Georgia. But climate change is making it happen more frequently, with ever-larger icebergs in the waters around Antarctica.
	Hydrogen becomes a superfluid at nanoscale, confirming 50-year-old prediction Hydrogen nano-clusters at low temperatures display 'superfluidity'—a quantum state of frictionless flow only previously observed in helium.
	Consumption of omega-3 weakens insulin resistance in non-obese rats, study shows A Brazilian study published in the journal Nutrients suggests that fish oil can weaken insulin resistance and reduce glucose intolerance by modulating the body's inflammatory response.
	How many languages can babies learn? Study shows how Ghanaian babies grow up speaking two to six languages Africa is a multilingual continent and many adults speak several languages fluently. An empirical study by a research team led by the Potsdam psycholinguists Prof. Dr. Natalie Boll-Avetisyan and Paul O. Omane now shows that the roots of this multilingualism can be found in infancy: In Ghana, most babies grow up multilingually, with most of them coming into contact with two to six languages and just as many regular speakers of each language.
	Physicists find unexpected crystals of electrons in new ultrathin material MIT physicists report the unexpected discovery of electrons forming crystalline structures in a material only billionths of a meter thick. The work adds to a gold mine of discoveries originating from the material, which the same team discovered only about three years ago.
	Student refines 100-year-old math problem, expanding wind energy possibilities A Penn State engineering student refined a century-old math problem into a simpler, more elegant form, making it easier to use and explore. Divya Tyagi's work expands research in aerodynamics, unlocking new possibilities in wind turbine design that Hermann Glauert, a British aerodynamicist and the original author, did not consider.
	Research suggests lovers fit into four categories Whether the binding glue of a pair is lust or companionship and commitment, people experiencing romantic love probably fit into one of four distinct categories of romantic lovers, according to the first-of-its-kind research from The Australian National University (ANU).
	Hofstadter's butterfly: Quantum fractal patterns visualized A team of scientists from Princeton University has measured the energies of electrons in a new class of quantum materials and has found them to follow a fractal pattern. Fractals are self-repeating patterns that occur on different length scales and can be seen in nature in a variety of settings, including snowflakes, ferns, and coastlines.
	Lead-208's doubly magic nucleus defies expectations with surprising shape properties In a surprising turn of events, an international team of scientists has found that lead-208 (208Pb), the heaviest known "doubly magic" nucleus, exhibits unexpected shape characteristics that current nuclear models fail to predict accurately.
	Fossil footprints reveal what may be the oldest known handcarts If you're a parent, you've probably tried, at some point, to navigate the supermarket with a trolley, and at least one child in tow. But our new study suggests there was an ancient equivalent, dating to 22,000 years ago. This handcart, without wheels, was used before wheeled vehicles were invented around 5,000 years ago in the Middle East.
	Drone captures narwhals using their tusks to explore, forage and play The narwhal (Monodon monoceros), an iconic whale of remote Arctic waters, is widely known for its long, spiral tusk, which is really an elongated tooth. The tusk, which is predominantly found in males and can grow up to 10 feet long, is one of the most fascinating traits in nature and the inspiration for myths such as the unicorn. It is believed to play a role in competition for mates, including mating displays. The tusk may have other uses and its function is still debated, primarily because few people have observed how these elusive animals use their tusks in the wild.
	High microplastic levels in bird lungs suggest widespread air pollution impact Microscopic plastic pollutants drifting through the air are lodging in the lungs of birds, a new University of Texas at Arlington study finds. Researchers worldwide are increasingly alarmed by how pervasive these harmful particles are in the air humans breathe and the food they eat.
	New theory suggests star mergers produce universe's highest-energy particles Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans. But while the existence of UHECRs has been known for 60 years, researchers have not succeeded in formulating a satisfactory explanation for their origin that explains all the observations.
	Inspired by Maxwell's demon, heat flow acts as a witness to quantum properties In a new study published in Physical Review Letters, scientists have discovered a novel approach to detecting the quantum properties of a system by simply using heat as a witness, requiring no direct measurement of the quant
