The Beginning of Fashion: Paleolithic Eye Needles and the Evolution of Clothing

by

Artist’s impression of decorated, custom-made clothing in the Upper Paleolithic. Credit: Mariana Ariza A team of researchers led by an archaeologist from the University of Sydney is the first to suggest that eye needles are a new technological innovation used to decorate clothing for social and cultural purposes. This marks the major shift from clothing … Read more

New computational microscopy technique offers a more direct route to sharp images

Concept of angular ptychographic imaging with closed-form method (APIC) and comparison between the reconstruction process of APIC and Fourier ptychographic microscopy (FPM). Credit: Nature communication (2024). DOI: 10.1038/s41467-024-49126-y For hundreds of years, the brightness and magnification of microscopes were ultimately limited by the physical properties of their optical lenses. Microscope makers pushed those limits by … Read more

Tiny bright objects discovered at dawn of universe stun scientists

by

Researchers investigated three mysterious objects in the early universe. Shown here are their color images, compiled from three NIRCam filter bands aboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (giving them the name “little red dots”), with some evidence of spatial structure at blue wavelengths.

New method for generating monochromatic light in storage rings

by

A pulsed laser co-propagates with the electron beam through the MLS U125 undulator and imposes an energy modulation. The same undulator serves as a radiator in the subsequent passes of the electron beam. The undulator radiation is detected by a fast photodiode, while the laser pulse is blocked from the detection path using an electro-optical … Read more

Research into recently discovered hydrothermal vents at a depth of 3,000 meters off the coast of Spitsbergen

by

The temperature reading at the outlet of the black smoker showed fluid temperatures in excess of 300°C. Credit: University of Bremen Hydrothermal vents are found all over the world at the intersections of floating tectonic plates. But there are still many hydrothermal fields yet to be discovered. During a 2022 MARIA S. MERIAN expedition, the … Read more

Astronomers discover two new satellite galaxies of the Milky Way

New NOvA results increase mystery surrounding neutrinos

by

Probability distributions for the value of the larger neutrino mass quadratic splitting of NOvA data when including antineutrino measurements at nuclear reactors. The normal (blue) mass ordering is preferred over the inverse (red) by a factor of 7:1.

Climate change is causing tropical rains to shift north, computer modeling suggests

by

Source: Pixabay/CC0 Public Domain A study led by a UC Riverside atmospheric scientist predicts that uncontrolled carbon emissions will cause tropical rainstorms to move north in the coming decades. This would have a major impact on agriculture and economies in the equatorial areas. The northward rainfall shift would be caused by complex changes in the … Read more

Asteroid rocks begin to reveal the origins of our solar system
