Two intermediate polars investigated by astronomers
By analyzing the long-term, high-cadence continuous photometry from NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have investigated UU Columbae and Swift J0939.7-3224—two intermediate polars. Results of the study, presented July.....»»
Saturday Citations: The first Goldilocks black hole; Toxoplasma gondii metabolism; pumping at the speed of muscle
This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard......»»
How astronomers work out the size of the solar system
The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity and magnetism......»»
Hubble finds evidence for rare black hole in Omega Centauri
An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster i.....»»
Hubble finds mysterious and elusive black hole
For years, astronomers have been searching for elusive intermediate-mass black holes. Now, Hubble has found evidence of one in Omega Centauri......»»
Researchers develop model to study heavy-quark recombination in quark-gluon plasma
Researchers from the HEFTY Topical Collaboration investigated the recombination of charm and bottom quarks into Bc mesons in the quark-gluon plasma (QGP). They have developed a transport model that simulates the kinetics of heavy-quark bound states t.....»»
Astronomers discover dozens of double-lined double white dwarf binaries
An international team of astronomers reports the discovery of 34 rare double-lined double white dwarf binary systems using the Intermediate-dispersion Spectrograph and Imaging System (ISIS) on the William Herschel Telescope (WHT). The finding was det.....»»
Light Is How Astronomers Read the Story of the Universe
Almost everything we know about the cosmos is conveyed by photons traveling across vast distances.....»»

Unexpected phage protein function discovered in bacteria battle
An unexpected find has enabled important progress to be made in the battle against harmful bacteria. An international team of researchers, led by Professor Peter Fineran from the University of Otago, investigated a particular protein used by bacteria.....»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
Astronomers suggest up to 60% of near-Earth objects could be dark comets
Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a University o.....»»
Study investigates the nature of very-high energy gamma-ray source TeV J2032+4130
Using the High-Altitude Water Cherenkov (HAWC) observatory, an international team of astronomers has observed a very-high energy gamma-ray source designated TeV J2032+4130. Results of the observational campaign, presented July 3 on the preprint serve.....»»
Pigs are social but only dogs are attached, companion animal study finds
Researchers at the ELTE Department of Ethology in Budapest investigated whether an infant-mother analog attachment bond arises in intensively human-socialized companion pigs towards their owners similar to companion dogs......»»
Evidence of water vapor detected in the atmosphere of Smertrios
Using the CARMENES spectrograph, astronomers have found evidence of water vapor in the atmosphere of a hot Saturn exoplanet designated HD 149026 b, dubbed Smertrios. The finding, reported in a research paper published on the preprint server arXiv, co.....»»
Astronomers find surprising ice world in the habitable zone with JWST data
A team of astronomers has identified a temperate exoplanet as a promising super-Earth ice or water world......»»
Low-cost depth imaging sensors achieve 97% accuracy in rapid plant disease detection
A research team has investigated low-cost depth imaging sensors with the objective of automating plant pathology tests. The team achieved 97% accuracy in distinguishing between resistant and susceptible plants based on cotyledon loss. This method ope.....»»
Study reveals key gene in Delphinium petal differentiation
A recent study investigated the role of the APETALA3–3 ortholog in shaping the diverse morphologies of petals in Delphinium anthriscifolium. This gene, previously known for its function in petal identity, is now revealed to be a key player in the i.....»»
Two new variable stars detected in globular cluster NGC 6558
An international team of astronomers has conducted a survey of variable stars in the field of a globular cluster known as NGC 6558. As a result, they identified dozens of variables, out of which two turned out to be new cluster members. The finding w.....»»
Scientists investigate fast reaction dynamics in synthetic molecules immobilized in porous protein cages
Immobilizing small synthetic molecules inside protein crystals proves to be a promising avenue for studying intermediate compounds formed during chemical reactions, report scientists from Tokyo Tech. By integrating this method with time-resolved seri.....»»
Whether children lie depends on the social environment, says study
Everyone lies—some more, some less. Children are no different. An international team of economists has now investigated the influence of the parental home and upbringing on a child's propensity to lie......»»
