 Dear olivier hartmanshenn,

	Physicists find a new way to represent π While investigating how string theory can be used to explain certain physical phenomena, scientists at the Indian Institute of Science (IISc) have stumbled upon on a new series representation for the irrational number π. It provides an easier way to extract π from calculations involved in deciphering processes like the quantum scattering of high-energy particles.
	NASA again delays Boeing Starliner's return home NASA said June 14 that the Boeing Starliner and its crew will now return to Earth from the International Space Station no earlier than Saturday, June 22.
	Researchers find wave activity on Titan may be strong enough to erode the coastlines of lakes and seas Titan, Saturn's largest moon, is the only other planetary body in the solar system that currently hosts active rivers, lakes, and seas. These otherworldly river systems are thought to be filled with liquid methane and ethane that flows into wide lakes and seas, some as large as the Great Lakes on Earth.
	A black hole of inexplicable mass: JWST observations reveal a mature quasar at cosmic dawn The James Webb Space Telescope observed a galaxy in a particularly young stage of the universe. Looking back into the past, it became clear that the light from the galaxy called J1120+0641 took almost as long to reach Earth as the universe has taken to develop to the present day. It is inexplicable how the black hole at its center could have weighed over a billion solar masses back then, as independent measurements have shown. The findings are published in the journal Nature Astronomy.
	Groundbreaking discovery: How researchers found remnants of Earth's primordial crust near Perth Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of.
	Researchers create new class of materials called 'glassy gels' Researchers have created a new class of materials called "glassy gels" that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.
	Einstein's other theory of gravity could have the recipe to relieve 'Hubble trouble' A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can't.
	Study finds link between genetics and coffee intake It's 9 a.m. and coffee shops are bustling with the line for the drive-thru wrapped around the building. This is a common occurrence around the globe as coffee is one of the most widely consumed beverages.
	Restored rat-free islands could support hundreds of thousands more breeding seabirds Hundreds of thousands more breeding pairs of seabirds could return to remote island archipelagos if invasive rats were removed and native vegetation restored, a new paper finds.
	Astronomers find black holes created in mergers carry information about their ancestors Astronomers believe that at the heart of most, if not all, galaxies sits a titanic black hole with a mass that is millions or even billions of times that of our sun. These supermassive black holes cannot be directly created through the collapse of a massive star, as is the case with stellar mass black holes with masses tens of times that of the sun, as no star is large enough to birth such a huge object.
	High-temperature superconductivity: Exploring quadratic electron-phonon coupling A new study published in Physical Review Letters (PRL) explores the potential of quadratic electron-phonon coupling to enhance superconductivity through the formation of quantum bipolarons.
	A method to reversibly control Casimir forces using external magnetic fields The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short distance apart. Studies have shown that this force can be either be attractive or repulsive, depending on the dielectric and magnetic properties of the materials used in experiments.
	New analysis determines ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere—a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa.
	Scientists investigate the origins of the Crab Nebula with James Webb Space Telescope A team of scientists used the NASA/ESA/CSA James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope's MIRI (Mid-Infared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that are helping to clarify the Crab Nebula's history.
	Satellites find that snow didn't offset southwestern US groundwater loss Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data.
	The ornate horns of ancient marvel Lokiceratops point to evolutionary insights What do you get when you cross Norse mythology with a 78-million-year-old ancestor to the Triceratops? Answer: Lokiceratops rangiformis, a plant-eating dinosaur with a very fancy set of horns.
	New simulations reveal hot neutrinos trapped during neutron star collisions When stars collapse, they can leave behind incredibly dense but relatively small and cold remnants called neutron stars. If two stars collapse in close proximity, the leftover binary neutron stars spiral in and eventually collide, and the interface where the two stars begin merging becomes incredibly hot.
	Many more bacteria produce greenhouse gases than previously thought, study finds Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas nitrous oxide (N2O) as a byproduct, the third-most potent greenhouse gas, after carbon dioxide and methane.
	Researchers invent 100% biodegradable 'barley plastic' A biofriendly new material made from barley starch blended with fiber from sugarbeet waste—a strong material that turns into compost should it end up in nature—has been created at the University of Copenhagen. In the long term, the researchers hope that their invention can help put the brakes on plastic pollution while reducing the climate footprint of plastic production.
	Study finds US does not have housing shortage, but shortage of affordable housin
