Does Private Equity Investment in Healthcare Benefit Patients? Evidence from Nursing Homes

The summary of a study by National Bureau of Economic Research: The past two decades have seen a rapid increase in Private Equity (PE) investment in healthcare, a sector in which intensive government subsidy and market frictions could lead high-powered for-profit incentives to be misaligned with the social goal of affordable, quality care. This paper studies [PDF] the effects of PE…

Scientists image a bright meteoroid explosion in Jupiter’s atmosphere

From aboard the Juno spacecraft, a Southwest Research Institute-led instrument observing auroras serendipitously spotted a bright flash above Jupiter’s clouds last spring. The Ultraviolet Spectrograph (UVS) team studied the data and determined that they had captured a bolide, an extremely bright meteoroid explosion in the gas giant’s upper atmosphere.

Scientists claim that all high-energy cosmic neutrinos are born by quasars

Scientists of the P. N. Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), the Moscow Institute of Physics and Technology (MIPT) and the Institute for Nuclear Research of RAS (INR RAS) have studied the arrival directions of astrophysical neutrinos with energies more than a trillion electronvolts (TeV) and came to an unexpected conclusion: all of them are born…

New storage medium uses physical properties of antiferromagnetic material

Using nanoscale quantum sensors, an international research team has succeeded in exploring certain previously uncharted physical properties of an antiferromagnetic material. Based on their results, the researchers developed a concept for a new storage medium published in the journal Nature Physics. The project was coordinated by researchers from the Department of Physics and the Swiss Nanoscience Institute at the University of…

Astronomers see star with dust disc that is being fed by surrounding material

An international team of astronomers including Leiden scientists publishes the image of a young star with a surrounding dust disk that is still being fed from its surroundings. The phenomenon around the star SU Aur may explain why so many exoplanets are not neatly aligned with their star. The European Southern Observatory (ESO) has declared the image “Photo of the Week.”…

Research reveals stellar kinematics of the galactic disc

By using a sample of 118945 red giant branch (RGB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, Dr. Wu Yaqian from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) investigated the stellar kinematics of the galactic disc in 7 Source: https://phys.org/news/2021-02-reveals-stellar-kinematics-galactic-disc.html…

Can air pollution help us find alien life?

To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres. Source: https://earthsky.org/space/can-pollution-help-us-find-alien-life…

Repotting Plants Without Killing Them

Repotting plants can seem like an intimidating or messy task, but with the right information, and a little practice, it is a rather fun activity for you and your plants. In this article: What Does Repotting Plants Mean? Why Is It Important to Repot Plants? What Are the Signs That Plants Need Repotting? When Is…Continue Reading
