Quasars as the new cosmic standard candles
In 1929, Edwin Hubble published observations that galaxies' distances and velocities are correlated, with the distances determined using their Cepheid stars. Harvard astronomer Henrietta Swan Leavitt had discovered that a Cepheid star varies periodic.....»»
Saturday Citations: All that sparkles is plastic; woke tree diversity; the gravitational basin in which we reside
This week, astronomers considered whether dark energy varies over cosmic timescales. Via neutron analysis, physicists revealed that some Early Iron Age swords were altered recently by swindlers in order to be more historically exciting. And a profess.....»»
Dark energy: Could the mysterious force we think of as constant actually vary over cosmic time?
,As I finished my Ph.D. in 1992, the universe was full of mystery—we didn't even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of these basic facts since the discovery of the cosmic.....»»
Cosmic-ray neutron rover assists in estimating mesoscale soil moisture on eastern Qinghai-Tibetan plateau
Soil water resources are crucial for hydrological processes and ecosystem functions on the Qinghai-Tibetan Plateau. However, accurately measuring soil moisture distribution in this region is challenging due to diverse ecosystems, complex terrain, and.....»»
How London’s Crystal Palace was built so quickly
New study finds it was the earliest-known building to use a standard screw thread. London's Great Exhibition of 1851 attracted some 6 million people eager to experience more than.....»»
Traces of antimatter in cosmic rays reopen the search for "WIMPs" as dark matter
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is......»»
Aqara’s new smart lock doesn’t use a deadbolt, offers Matter support
The Aqara Smart Lock U300 is a lever lock that doesn't use a deadbolt. Instead, it's a standard latch lock that can be used both indoors or outdoors......»»
New triple star system sets shortest orbital period record
Professional and amateur astronomers have made a groundbreaking discovery with the help of artificial intelligence, identifying a unique triple star system named TIC 290061484. This stellar trio was uncovered through cosmic "strobe lights" observed b.....»»
London Standard"s AI-generated review, by late art critic Brian Sewell, exposes a significant philosophical threat
For the first issue in its new weekly print edition, the London Standard has run an experiment in the form of an AI-generated review of the National Gallery's Van Gogh: Poets and Lovers exhibition, written in the style of late art critic Brian Sewell.....»»
Saturday Citations: Octopuses as shift supervisors for fish; universe confounds standard model; extremely old cheese
This week, biologists tracked down a mysterious group of orcas near Chile; Hubble spotted a black hole jet that causes stars along its trajectory to erupt; and researchers explained mysterious craters that began appearing in Siberian permafrost in th.....»»
iFixit iPhone 16 Pro teardown: New battery, Camera Control compromise, much more repairable
The iFixit iPhone 16 Pro teardown video is now up (below), and the company has highlighted some differences over last year’s model. This follows its earlier teardown of the standard and Plus models. Top of the list, and exclusive to the iPhone 1.....»»
Active Directory compromise: Cybersecurity agencies provide guidance
Active Directory (AD), Microsoft’s on-premises directory service for Windows domain networks, is so widely used for enterprise identity and access management that compromising it has become almost a standard step in cyber intrusions. “Act.....»»
Advanced data shed light on gravitational basins of attraction that shape the movement of galaxies
A new study has mapped out the gravitational basins of attraction in the local universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. The study has been published in Nature Astronomy......»»
Millennial Black women navigate when and where to express style
Millennial Black women feel they have autonomy and flexibility in navigating beauty standards in their personal lives, according to a new qualitative study. But at work, they feel compelled to adapt to a more restrictive beauty standard......»»
Building better bone grafts: Nanofibrous scaffolds to activate two main collagen receptors in bone cells
Each year, about 2.2 million bone-grafting procedures are performed worldwide, the gold standard of care being autografting, which uses the patient's own bone for tooth implantation and to repair and reconstruct parts of the mouth, face and skull......»»
Active Directory compromise: Cybersecurity agencies provde guidance

Apple iPhone 16 vs. iPhone 15: Time for an upgrade?
The iPhone 16 breathes new life into Apple's standard iPhone lineup, but is it a worthy upgrade over the iPhone 15? We walk you through the differences......»»
Murine study suggests cosmic radiation in outer space may affect long-term cognition
During missions into outer space, galactic cosmic radiation (GCR) will penetrate current spacecraft shielding and thus pose a significant risk to human health......»»
Study raises questions about validity of standard model of solar flares
Solar flares are extremely intense events that occur in the sun's atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electro.....»»
Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»
Better than blood tests? Nanoparticle potential found for assessing kidneys
In a study published July 29 in Advanced Materials, University of Texas at Dallas researchers found that X-rays of the kidneys using gold nanoparticles as a contrast agent might be more accurate in detecting kidney disease than standard laboratory bl.....»»
