Scientists have discovered rare earth metal terbium in the atmosphere of KELT-9b, an exoplanet located approximately 670 light-years away. This is the first time that the extremely rare element has been found on a distant planet. KELT-9b is known as a hot Jupiter, a gas giant that orbits a blue supergiant star on an extremely

Dementia is a brain disease that affects approximately 55 million people worldwide, leading to the loss of cognitive functions. While early signs of dementia may be subtle, researchers have identified other noticeable changes to the body that can indicate dementia risk. A recent study suggests that hearing difficulties may be a warning sign of dementia
Scientists from SLAC National Accelerator Laboratory have used two ultrafast X-ray spectroscopy techniques to capture the movement of a molecule called ferricyanide. This is the first time that the movement has been recorded in this way, and the team thinks that their approach could help map more complex chemical reactions, such as oxygen transportation in
Chemists at the University of California, Los Angeles have discovered that 1,2,3-cyclohexatriene, a benzene isomer, has the potential to be a useful reagent in organic synthesis. Although it has been considered too unstable to be of use for many years, it is substantially higher in energy than benzene, making it a promising candidate for synthesizing
Astronomers have observed a flare of light as a dying star engulfs and destroys one of its orbiting planets, providing valuable insight into what happens to a planetary system as a star enters its death throes. This is the first time such an event has been observed, despite being theorized for some time. Process of
The Grand Canyon is visited by millions of people every year, but despite this, not all of its rock layers have been named or studied. In a new report published in the journal Geosphere, a UNLV-led research team has identified and named a previously unexplored 500 million-year-old rock formation in the Grand Canyon. The newly
Researchers have been trying to develop more energy-efficient and faster machine learning systems that can replicate the versatile computational abilities of biological neurons for decades. One promising approach has been the use of memristors – electronic components that can store a value by modifying their conductance and then use that value for in-memory processing. However,
New research has shown that significant changes in gut microbiota happen in the early stages of Parkinson’s disease and can begin before the onset of symptoms. Scientists from China and Germany studied the bacteria in the guts of individuals with early Parkinson’s disease, REM sleep behavior disorder (RBD), their close relatives, and healthy people. The
Volcanic eruptions can have severe global impacts, but accurately measuring the size of such eruptions can be challenging. To classify the size of volcanic eruptions, volcanologists estimate the magma volume and deposition volume. However, it is often difficult to determine these values accurately, making it challenging to infer the actual volume of magma and measure
The production of medication requires the isolation of active pharmaceutical ingredients from suspensions and drying them. This process relies on a human operator to monitor the industrial dryer, agitate the material, and observe the compound’s properties to ensure it is suitable for compression into medicine. However, this process is subjective and depends heavily on the
Astronomers have detected the chemical imprints of the first stars to exist in the universe, which exploded billions of years ago. The remains of these stars are difficult to find as they exploded too far away to detect with current instruments. However, the material they left behind during their explosions, such as carbon, oxygen and
Factorizing large numbers is a difficult task that requires a significant amount of computational effort. However, physicists at the University of Innsbruck, Austria, have created a new blueprint for a quantum computer that can solve the factorization problem. This is a significant development as factorization is a cornerstone of modern cryptography. Current Computing Methods Today’s
In the field of physics, it is common to encounter different scales that can be separately described. For instance, the movement of an elephant walking in a zoo does not affect the Earth’s orbit around the sun. Similarly, the behavior of particles in materials research can be described on different scales. However, finding out which
Proteins play a vital role in carrying out various biological functions through interactions, such as the formation of protein complexes. The localization and microenvironments within cells are crucial for maintaining the structure and function of these complexes. Chemical cross-linking mass spectrometry (CXMS) is a technique used for analyzing protein complexes in living cells. However, it
Researchers have developed an algorithm that can locate any point on Earth using signals from multi-constellation Low Earth Orbit (LEO) satellites. The algorithm can exploit signals broadcast by Starlink, OneWeb, Orbcomm, and Iridium satellites, without assistance from the satellite operators. The Study Led by Zak Kassas, a professor of electrical and computer engineering at The
