Geological evidence suggests that rivers and oceans may have been prominent features of Mars’s early history. The Red planet is smaller than the earth, with less gravity and a thinner atmosphere. The theory suggests that over time, as liquid water evaporated, more and more of it escaped into space. A new study based on data…

Jupiter’s auroras are the most powerful in the solar system. What’s puzzling is, despite the magnitudes of these potentials at Jupiter, they are observed only sometimes and are not the source of the most intense auroras, as they are on Earth. At Jupiter, the brightest auroras are caused by some turbulent acceleration process that remains…

Our Universe is continually expanding. The reason behind this expansion is still unknown. Scientists at the Dark Energy Survey (DES) have a way to find out the reason. By combining measurements of the distribution of matter, galaxies, and galaxy clusters, it is possible to determine what is going on. Achieving this goal is quite tricky.…

A neutron star can rotate several times per second, and its whirling magnetic field prompts beams of radio waves, visible light, X-rays, and gamma rays. When these beams sweep past Earth, astronomers observe clock-like pulses of emission and classify the object as a pulsar. Until now, astronomers have observed 2,800 pulsars. Among all observed pulsars,…

One out of three women is affected with heavy menstrual bleeding. Although common and debilitating, its causes are poorly understood.  Due to heavy periods, women are less likely to go outside. In extreme cases, women require blood transfusion as problematic menstrual bleeding can have far negative impacts on quality of life.  In a new study,…

First results from the Muon g-2 experiment at Fermilab have strengthened evidence of new physics. The centerpiece of the experiment is a 50-foot-diameter superconducting magnetic storage ring, which sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the precession…

Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy, and despite improvements in genetic and pharmacological pathology, its management remains a significant challenge. In a new study, scientists have sown that supplementing mice with Urolithin A can delay Duchenne Muscular Dystrophy’s progression (DMD). The discovery offers unique treatments for DMD and highlights the critical…

In a new study appearing in the Astronomical Journal, scientists reported the three fastest-spinning brown dwarfs ever found. The discovery was made using data from NASA‘s Spitzer Space Telescope. In the study, scientists made new speed measurements of these quasars. They also argued that these three rapid rotators could be approaching a spin speed limit…

Peering back 10 billion years into the universe’s past, NASA’s Hubble Space Telescope detected a pair of quasars that are so close to each other. Because of their proximity, they appear as a single object. According to scientists, the reason behind this proximity is that they reside in the cores of two merging galaxies. The…

Using metasurfaces, infrared light and artificial intelligence, EPFL scientists have come up with AI-powered nanosensors that can observe all major biomolecule classes of the nanoworld without disturbing them. Hatice Altug, the head of the Bionanophotonic Systems Laboratory said, “Tuning into this tiny world and being able to differentiate between proteins, lipids, nucleic acids and carbohydrates…

The rise of atmospheric oxygen fundamentally changed the chemistry of surficial environments and the nature of Earth’s habitability. Previously it was believed that atmospheric oxygen significantly raised about 2.43 billion years ago. A new study suggests that great oxidation episodes started 100 million years later than previously thought. For this study, an international research team,…

The Sun emits the energy required to sustain life on Earth and drive our planet’s atmospheric circulation. However, establishing a solid physical connection between solar and tropospheric variability has posed a considerable challenge. North Atlantic Oscillation (NAO) or the El Nino Southern Oscillation events are little more than anecdotal. These events have several seasonal climate…
