Measuring dark matter halos around ancient quasars
At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are activated by the presence of massive dark matter halos (D.....»»
Integrated space-ground technologies empower archaeological research into ancient tombs
A team of international researchers has employed an integrated approach to uncover the mysteries of the Eastern Mausoleum of Qin State, an ancient royal burial site from China's Warring States period......»»
Investigating the impact of ultralight dark matter on gravitational wave signals
A recent study in Physical Review Letters explores the effects of ultralight dark matter in extreme-mass-ratio inspirals (EMRIs), which could be detected by future space-based gravitational wave detectors like LISA (Laser Interferometer Space Antenna.....»»
MechWarrior 5: Clans is supposed to be newbie-friendly, and I put it to the test
All the kit balancing, squad leading, and lore you could want, if you want it. It is a matter of settled law on the Judge John Hodgman podcast that people like what they like, and.....»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»
First results from the Axion Dark-Matter Birefringent Cavity experiment establish a new technique for axion search
Researchers at MIT recently published the first results of an experiment aimed at searching for axion dark matter by probing the axion-induced birefringence of electromagnetic waves. While these findings, published in Physical Review Letters, did not.....»»
Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
Plankton balloon to six times their size in newly discovered mode of oceanic travel
Many plankton journey from the cold, dark depths of our oceans to the surface, only to eventually drift down again into the darkness in a perpetual rhythm. Yet, how single-celled phytoplankton, most of which have no appendages to help them swim, make.....»»
In search of evidence of ancient human existence, researchers traverse the inhospitable Namib desert
Strewn across the Namib desert is a treasure trove of stone tools of which little is known because getting to them is so difficult. There are few roads and vehicles have limited access in this protected area that lies in the desert of western Namibia.....»»
New method for measuring luminescence lifetime offers versatility in scientific imaging
Oxygen is a key molecule for life, and in order to understand ecosystem dynamics it can be important to follow its ways in much detail. Optical sensors that use luminescent dyes have long been used to map oxygen levels in marine systems. Oxygen reduc.....»»
Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
New technique enhances precision in measuring short-lived atomic nuclei
Researchers at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) have introduced a technique, Tune-IMS, designed to improve the precision of isochronous mass spectrometry (IMS) in measuring short-lived atomic nuclei. The development offers refin.....»»
Ancient ‘Age of Dinosaurs’ Seafloor Found beneath Pacific Ocean
A vast, ancient slab of seafloor plunged beneath the Pacific Ocean and has hovered in Earth’s mantle for more than 120 million years, a new study suggests.....»»
Study claims ‘Jedi’ rodents can move matter without touching it
A new study seems to suggest that “Jedi” rodents don’t actually vocalize just to make noises. Instead, the study claims that they vocalize to “shake … The post Study claims ‘Jedi’ rodents can move matter without touching it appeared.....»»
Biochar nanocomposite enhances detection of acetaminophen and uric acid in urine
In recent years, the excessive use of acetaminophen (APAP) has become a significant human hazard and social burden. Rapid and automated electrochemical detection has emerged as a crucial method for measuring APAP concentration in human urine......»»
Electrophysiology study shows how ant toxin causes extreme pain
University of Queensland researchers have uncovered the workings of ant venom by measuring electric currents through individual channels in cells to understand how it causes pain......»»
Stephen King’s Fairy Tale will now be a 10-episode A24 TV series, not a movie

The neutron lifetime problem—and its possible solution
Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes.....»»
