A highly processed diet is enriched with refined carbohydrates, saturated fats and lacks fiber. Previous studies have suggested that this diet negatively impacts brain health and cognitive function. However, mechanisms by which PD affects the aged brain are unknown. To fill this knowledge gap, scientists at the Ohio State University conducted a study on aging…
People with diabetes either need to collect blood samples or embed sensors into their skin to monitor glucose levels. Both ways are painful. Now, Penn State scientists have developed a new wearable device to measure blood sugar levels. The device is less intrusive, noninvasive, and low-cost. It is able to monitor glucose levels in sweat…
Observations by the NASA/ESA Hubble Space Telescope recently revealed water vapour in the atmosphere of Ganymede, one of Jupiter’s moons. A new analysis of archival images and spectra has now revealed that water vapour is also present in the atmosphere of Jupiter’s icy moon Europa. The analysis found that a water vapour atmosphere is present…
Small-molecule responsive protein switches are crucial components to control synthetic cellular activities. However, their repertoire is insufficient for many applications. In a new study, EPFL scientists developed new controlled proteins by using a computational protein design strategy. The proteins can be used to switch cellular activities on and off like a light bulb. Sailan Shui,…
In the crowded environment of the universe, galaxies can fly past each other. Sometimes, they can collide and merge. When such phenomena occur, it affects the dynamics and morphology of these galaxies. Galaxy fly-bys are different than galaxy mergers. During this, galaxies come close and exert a tremendous gravitational pull on each other and then…
Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile, astronomers have imaged 42 of the largest objects in the asteroid belt, located between Mars and Jupiter. Never before had such a large group of asteroids been imaged so sharply. The observations reveal a wide range of peculiar shapes, from spherical to dog-bone,…
Previously, it was thought that Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history. But, a new study using climate models suggests that the ocean never formed on Venus. The research was conducted by the team of astrophysicists led by the University…
An international team of astronomers reported that more than 1,650 fast radio bursts (FRBs) originated from a single source in space. These independent Fast Radio Bursts are coming from the source over 47 days, making them the largest-ever observed set of FRBs. Using the Five-hundred-meter Aperture Spherical Telescope (FAST) in China, the team identified the…
Around 5,000 years ago, a sloth smaller than a black bear roamed the forest floor of the Dominican Republic in the Caribbean Sea. The sloth that used to live a lowland life was different from its cousins. Now, scientists at Johns Hopkins Medicine and the Philadelphia College of Osteopathic Medicine have discovered the species of…
Are you fascinated by space? Do you want to explore? A new Virtual envoirnment will let you do that. Scientists at EPFL have developed a virtual environment that allows you to enter the most comprehensive virtual universe. Using the latest astrophysical and cosmological data, they have developed an open-source software called VIRUP, Virtual Reality Universe…
