The mystery of consciousness shows there may be a limit to what science alone can achieve
The progress of science in the last 400 years is mind blowing. Who would have thought we'd be able to trace the history of our universe to its origins 14 billion years ago? Science has increased the length and the quality of our lives, and the techno.....»»
Largest-ever map of universe"s active supermassive black holes released
Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objec.....»»
The cosmic neutrino background would tell us plenty about the universe, says researcher
Readers of Universe Today are probably already familiar with the concept of the cosmic microwave background (CMB). Its serendipitous discovery by a pair of radio astronomers at Bell Labs is the stuff of astronomical legend. Over the past decades, it.....»»
Engineers manage a first: Measuring pH in cell condensates
Scientists trying to understand the physical and chemical properties that govern biomolecular condensates now have a crucial way to measure pH and other emergent properties of these enigmatic, albeit important, cellular compartments......»»

Researchers develop a new type of frequency comb that promises to further boost the accuracy of timekeeping
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication......»»
Apple looks beyond health for a large array of future Apple Watch sensors
Apple has been researching what more sensors can possibly be fitted into an Apple Watch, and specifically ones that are not related to health.Apple Watch already has many health sensors, but now it may be looking to measure moreIt's practically an in.....»»
Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»
AI for astrophysics: Algorithms help chart the origins of heavy elements
The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time......»»
New method finds higher carnivorous dinosaur biodiversity in Kem Kem beds of Morocco
An international team of paleontologists from The Netherlands, the UK, Argentina, Germany and Belgium applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phyl.....»»
Condor telescope reveals a new world for astrophysicists
A new telescope called the "Condor Array Telescope" may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical Society (MNRAS) this month,.....»»
Archeoastronomy uses the rare times and places of previous total solar eclipses to help us measure history
In 648 BCE, the Greek poet Archilochus wrote that "nothing can be surprising any more or impossible or miraculous, now that Zeus, father of the Olympians has made night out of noonday, hiding the light of the gleaming sun.".....»»
Study: Conflicting values for Hubble Constant not due to measurement error
Something else is influencing the expansion rate of the Universe. Enlarge / This image of NGC 5468, about 130 million light-years from Earth, combines data from the Hubble and Webb space telescopes. (credit: NASA/ESA/CSA/STScI/A.....»»
Giving particle detectors a boost: New device acts like a superconductivity switch
In particle colliders that reveal the hidden secrets of the tiniest constituents of our universe, minute particles leave behind extremely faint electrical traces when they are generated in enormous collisions. Some detectors in these facilities use s.....»»
The expansion rate of the universe still has scientists baffled
The question of how fast the universe is expanding confounds scientists, and new research using James Webb and Hubble doesn't make the answer any clearer......»»
