Hardly any gemstone is more difficult to find than diamonds. Geologists from ETH Zurich and the University of Melbourne have now established a link between their occurrence and the mineral olivine. This could make the search for diamonds easier in the future. In brief The abundance of magnesium and iron in the mineral olivine provides information on whether or not diamonds could be present in a kimberlite rock sample. The more magnesium is found in the olivine, the more likely…
Researchers show that the SETI Ellipsoid method can leverage continuous, wide-field sky surveys, significantly enhancing our ability to detect these potential signals. In a paper published in the Astronomical Journal, a team of researchers from the SETI Institute, Berkeley SETI Research Center and the University of Washington reported an exciting development for the field of astrophysics and the search for extraterrestrial intelligence (SETI), using observations from the Transiting Exoplanet Survey Satellite (TESS) mission to monitor the SETI Ellipsoid, a method for identifying…
One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly – possibly at a rate of trillions of particles per second. We know it exists because we can see the effects of its gravity, but experiments to date have so far failed to detect it. Taking advantage of the most…
An international team led by researchers from AEI Hannover, MPIfR Bonn and NRAO/USA has discovered ten rapidly rotating neutron stars in the globular cluster Terzan 5. Many of them are in unusual and rare binaries, including a potential candidate for a record-breaking double neutron star, a pulsar in an extremely elliptical orbit, and several “spider” systems in which the neutron stars are evaporating their companions. These finds in data from the MeerKAT radio telescope array increase the number of known…
Gemini North’s MAROON-X instrument finds evidence for four mini-Earth exoplanets around our famous cosmic neighbor Barnard’s Star For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth [1]. Barnard’s Star is classified as a red dwarf — low-mass stars that often host closely-packed planetary systems, often with multiple rocky planets. Red dwarfs are extremely numerous in the Universe, so scientists…
UCSF researchers have found that some HIV patients treated with antiretroviral therapy early after infection do test negative, at some point, for the virus. Study findings showed this result in six of 87 patients.
“First, these patients are not cured. When these patients went off therapy, HIV virus levels rebounded. These results do show that with effective early treatment that reduces the virus to very low levels, the immune system may have less antibody response to HIV,” said the study&#
