AI can reveal new cell biology just by looking at images

AI learns how to recognize and classify different dog breeds from images. A new machine learning method from CZ Biohub now makes it possible to classify and compare different human proteins from fluorescence microscopy images. Credit: CZ Biohub Humans are good at looking at pictures and finding patterns or making comparisons. Take a look at a collection of dog photos, for example, and you can sort them by color, ear size, face shape, and so on. But can you compare them quantitatively? And perhaps more interestingly, can machines extract meaningful information from images that humans cannot? Now Stanford University’s Chan Zuckerberg Biohub team of scientists have developed a machine learning method to quantitatively analyze and compare images—in this case microscopic images of proteins—without any prior knowledge. As reported in Natural Method , their algorithm, dubbed “cytoself”, provides rich and detailed information about the loc

The astrophotography competition presents spectacular heavenly images

With his love of science fiction and photography, it seems that Ian Inverarity has always been destined to become involved with astrophotography. Key points: A mechanical engineer from Adelaide has won this year’s David Malin astrophotography award Amateur astrophotography is booming as a hobby as technology becomes more advanced and affordable This year’s competition entered the smartphone category for the first time Mechanical engineers have been capturing the wonders of the night sky for several years now, traveling to regional South Australia in search of the perfect shot. He said the addictive pursuit took him to Gawler, north of Adelaide, about once a month. And many nights and hours in darkness have paid off, with his photo of an old gum tree at Gawler shrouded in mist before the Milky Way picks up this year’s David Malin astrophotography award in New South Wales. “It’s relatively unusual. Out of the seven years or so I’ve been going there, I’ve only encountered fog at night,” I

Scientists capture images of atoms 'swimming' in liquid

Graphene scientists from The University of Manchester have created a new ‘nano-petri dish’ using a two-dimensional (2D) material to create a new method of observing how atoms move in a liquid. Published in the journal Nature, a team led by researchers based at the National Graphene Institute (NGI) used stacks of 2D materials such as graphene to trap liquids to better understand how the presence of liquids changes the behavior of solids. The team was able to capture images of a single atom ‘swimming’ in a liquid for the first time. These findings could have far-reaching implications for the future development of green technologies such as hydrogen production. When a solid surface comes into contact with a liquid, the two substances change their configuration in response to the proximity of the other. Such atomic-scale interactions at the solid-liquid interface regulate the behavior of batteries and fuel cells for clean electricity generation, as well as determine the efficiency of cle

The “Grandest Canyon” in the Solar System: Mars Express Captures Stunning Images of the Breathtaking Canyons of Mars

The Webb Space Telescope captures Stephan's Quintet in a mosaic of nearly 1,000 images

Image
by Jeremy Gray posted Friday, July 15, 2022 at 15:00 EDT Yesterday, we saw Webb’s incredible photos of the Southern Ring Nebula. On Wednesday, the focus was Webb’s first deep-plane image of SMACS 0723, the sharpest and deepest image of the universe captured so far. Now it’s time to take a look at Stephan’s Quintet, as imaged by the Webb Near Infrared Camera (NIRCam) and Central Infrared Instrument (MIRI). The Quintet Stephan image is a large mosaic of nearly 1,000 images. This is Webb’s big image to date and contains over 150 million pixels. You can download the full 150MB .TIFF file here. All of these details allowed researchers to investigate how interactions between galaxies drove the evolution of galaxies in the early universe.

Two images of Jupiter leaked by the James Webb Telescope team

Two interesting images of the gas giant Jupiter leaked alongside the main image from the James Webb Space Telescope (JWST) released yesterday. Informal images, full resolution images released in yesterday’s major release style, but included in a NASA commissioning documents to demonstrate that the NIRCam (Near Infrared Camera) can track moving targets. The composite shows a short wavelength image of Jupiter on the left, and a long wavelength image on the right, revealing the dramatically different types of atmospheric conditions that JWST can see. Both images were taken with a 75 second exposure and they show the gas giant moons Europa, Thebe, and Metis. NASA noted that Europa’s shadow is also visible to the left of the Great Red Spot.

Two experts decipher the first images of the James Webb Space Telescope, and explain what we've learned

Image
Today we take a look at the release of the first batch of images captured by the James Webb Space Telescope. This is something we have both been waiting for for almost 25 years. Back in those days, we analyzed the first Hubble images of the distant universe, and the details they reveal are staggering compared to anything we’ve seen in ground-based images. It seems the bar has been raised once again, and Webb is set to herald a new era for astronomy and space research. Its large mirror helps it produce images that are two to three times sharper than Hubble’s, and that go much deeper into space (which means it can see dimmer sources). Webb was also able to see far redder infrared wavelengths, opening up new views of the universe. This is particularly important for studying the early universe because of “cosmological redshift,” a process that refers to the stretching of light (with the expansion of the universe) as it travels through cosmic space. It’s also useful for studying interes

James Webb Space Telescope: An astronomer describes the first stunning and newly released images

Image
The James Webb Space Telescope Team has released the first scientific-quality images of the new telescope. It contains the oldest galaxies ever seen by the human eye, evidence of the presence of water on a planet 1,000 light years away and incredible detail showing the birth and death of stars. Webb’s goal is to explore the origins – the universe, galaxies, stars and life – and the five images released on July 12, 2022, fulfill that promise. Once the instruments on board were cool and running smoothly, astronomers wasted no time getting Webb to work. Each first image contains sufficient data to produce its own primary scientific result. Webb was designed to collect light across the red to mid-infrared spectrum – the wavelengths of light that are blocked by Earth’s atmosphere. And with giant mirrors and shielding the infrared rays emitted by the Sun, Earth and Moon, Webb can produce images with a sharpness never before achieved by other telescopes. Rumors among professional astronom

Images of the Carina Nebula from the Webb and Hubble telescopes paint a stunning view of the universe

Image
A stellar nursery discovered more than 250 years ago will teach astronomers new things about how stars come to life with the help of sharp vision from the James Webb Space Telescope. The powerful new $10 billion observatory, located in space about 1 million miles from Earth, takes new images of the star-forming region within the Carina Nebula. The image captures incredible detail previously unseen by the Hubble Space Telescope. The Carina Nebula has been a popular target for study for many years because it exhibits cosmic events lasting for a very short time – only about 50,000 to 100,000 years. The nebula lies in the Milky Way about 7,600 light-years away and is home to other well-known cosmic objects, such as the Keyhole Nebula and the unstable supergiant star, Eta Carinae. Astronomers have given its features several pet names as well, such as Mystic Mountain and Cosmic Cliffs.
