According to scientists at MIT and elsewhere, there was a mysterious gap within the protoplanetary disk in the early solar system around 4.567 billion years ago, near the region where the asteroid belt resides today. This protoplanetary disk was used to rotate around the sun in the early solar system. Benjamin Weiss, professor of planetary…
NASA/ESA Hubble Space Telescope recently shared the image of a majestic spiral galaxy called NGC 4666. Located about 80 million light-years away in the constellation Virgo, the galaxy is a type of starburst galaxy, where a burst of star formation happens. The galaxy is originally discovered in 1784 by the German-born astronomer William Herschel. It…
How long, on average, a free neutron lives outside the confines of atomic nuclei? To find out the answer, an international team of physicists led by Indiana University conducted an experiment that captured neutrons. The temperatures of these neutrons are lowered to nearly absolute zero inside a “bathtub” lined with about 4,000 magnets. After waiting…
Radio waves contain noise that emerges from the random motion of the atoms in the things they are emitted from. One way to reduce this noise is to cool down the radio waves. Using a circuit analogous laser cooling technique, scientists at the Delft University of Technology have discovered a new way to cool radio…
Using W. M. Keck Observatory on Maunakea in Hawaii, astronomers have discovered a planetary system consisting of a Jupiter-like planet with a Jupiter-like orbit revolving around a white dwarf star. Lies about a quarter of the way towards the center of our Milky Way galaxy, the gas giant planet within the system just survived the…
A team of international scientists suggests that global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in unless there is a significant drop in CO2 emissions. The study was conducted using global climate model projections. These projections were based on time-dependent projections of atmospheric greenhouse…
MIT and Sweden scientists have developed a new kind of fiber called OmniFibers, that when used in garments, can sense how much it is being stretched or compressed. It then gives tactile feedback in the form of pressure, lateral stretch, or vibration. The fluid channel within the center of the fiber controls the fibers’ geometry.…
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…
