The Milky Way will probably devour all the tiny galaxies that surround it
The rapid disruption of smaller galaxies suggests they lack a bit of dark matter. Enlarge / An infrared image of one of the Milky Way's satellite galaxies. (credit: NASA/JPL-Caltech/STScI) We are not alone—at least as.....»»
The stone-eaters that threaten Iran"s ancient Persepolis
Conservationists at Persepolis, Iran's most iconic ancient site, are waging a delicate battle against an unlikely adversary: tiny but persistent lichens eroding the millennia-old monuments......»»
Saturday Citations: Permian-Triassic mystery solved; cute baby sighted; the nine-day 2023 seismic event
This week, a billionaire made a spacewalk, archaeologists found a new, isolated Neanderthal lineage and the James Webb Space Telescope revealed the extreme outskirts of the Milky Way. And a few other things happened:.....»»
Scientists discover crude oil decimates sea otter buoyancy
Sea otters are famed for their luscious pelts, but the fur almost led to their extinction. By 1938, only a tiny population of ~50 remained clinging to the central California coast. Since then, the mammals have battled back. However, the charismatic c.....»»
James Webb trains its sights on the Extreme Outer Galaxy
A gorgeous new image from the James Webb Space Telescope shows a bustling region of star formation at the distant edge of the Milky Way......»»
Combination and summary of ATLAS dark matter searches within 2HDM+a framework
In the 1930s, Swiss astronomer Fritz Zwicky observed that the velocities of galaxies in the Coma Cluster were too high to be maintained solely by the gravitational pull of luminous matter. He proposed the existence of some non-luminous matter within.....»»
An evolutionary battleground: Plants vs. microbes
Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can grow so fast that they can d.....»»
Webb peers into the Extreme Outer Galaxy
Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For co.....»»
Multiple ways to evolve tiny knee bone could have helped humans walk upright
The evolution of bones in primates' knees could have implications for how humans evolved to walk upright, a new study has found......»»
Whales are recovering from near extinction, but industrial fishing around Antarctica competes for their sole food source
The Southern Ocean encircling Antarctica is the world's largest feeding ground for baleen whales—species like humpbacks that filter tiny organisms from seawater for food. In the 20th century, whalers killed roughly 2 million large whales in the Sou.....»»
Atomic diffusion technique could lead to mass production of metal nanowires
A group from Nagoya University in Japan has created a new technique for growing the tiny metal nanowires (NWs) that are expected to be used in next-generation electronics. Their results suggest a way to mass produce pure metal NWs, which has until no.....»»
Could alternative meat meet a growing demand?
Inside a UC Davis engineering lab, tiny round pellets swirl in a brown liquid inside a 5-liter glass tank. The tank, a bioreactor, is brewing edible fungi high in protein and designed to look and taste like meat......»»
New mass spectrometry technology could transform tiny sample analysis
Mass spectrometry is a powerful technique that allows scientists to break down and identify the building blocks of just about anything by measuring the mass of the tiny particles of which something is comprised. It has a major limitation, however—a.....»»
Ultimate Ears Miniroll speaker is tiny, waterproof, and wearable
Ultimate Ears' latest portable Bluetooth speaker is also its smallest......»»
New measurements reveal the enormous halos that shroud all galaxies in the universe
Have you ever wanted to make a $150,000 gamble? If you're right, you open a new window to the universe. But if you're wrong, you've just wasted a lot of money and time......»»
Hidden, compact galaxies in the distant universe—searching for the secrets behind the little red dots
Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA's most powerful telescope, have found a class of galaxies that challenges even the most skillful creatures in mimicry—like the mimic octopus. This creature can imp.....»»
Tiny glass beads suggest the moon had active volcanoes when dinosaurs roamed Earth
Volcanoes were still erupting on the moon when dinosaurs roamed Earth, new research suggests......»»
Massive merger: Study reveals evidence for origin of supermassive black hole at galaxy"s center
The origins of aptly named supermassive black holes—which can weigh in at more than a million times the mass of the sun and reside in the center of most galaxies—remain one of the great mysteries of the cosmos......»»
Deep imaging techniques reveal that galaxies are much much bigger than previously thought
If this galaxy is typical, then the study, published today in Nature Astronomy, indicates that our galaxy is already interacting with its closest neighbor, Andromeda......»»
Global experts present early-stage recommendations for nanomedicine development
They're tiny drug-delivery systems 1,000 times smaller than a human hair, but while nanomedicines have long been hailed as the future for treating debilitating and life-threatening diseases, their journey from lab to patient has many challenges......»»
Study shows how amateur astronomers can aid in Jupiter weather monitoring
Jupiter's striking appearance comes from its stormy atmosphere. Swirling clouds surround the gas giant, and their distribution reflects the planet's weather. Scientists have used professional observatories such as the Very Large Telescope in Chile (w.....»»
