If Earth were an exoplanet, JWST would know there"s an intelligent civilization here
If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules su.....»»
Illuminating new horizons: Navigating nonlinear scattering with precision
In the intricate world of light, a journey through inhomogeneous media often leads to distortions in space, time, spectrum, and polarization. These distortions, detrimental to applications like optical manipulation, imaging, and communication, have l.....»»

The Top Programming Languages 2023
Welcome to IEEE Spectrum’s 10th annual rankings of the Top Programming Languages. While the way we put the TPL together has evolved over the past decade, the basics remain the same: to combine multiple metrics of popularity into a set of rankings.....»»
Exploring Io"s volcanic activity via Hubble and Webb telescopes
The two most powerful space telescopes ever built, NASA's James Webb Space Telescope (JWST) and Hubble Space Telescope, are about to gather data about the most volcanically body in the entire solar system, Jupiter's first Galilean moon, Io......»»
JWST plucks one single star out of a galaxy seen 12.5 billion years ago
After years of build-up and anticipation, the James Webb Space Telescope finally launched into orbit on December 25th, 2021 (what a Christmas present, huh?). Since then, the stunning images and data it has returned have proven beyond a doubt that it.....»»
How old is the universe exactly? A new theory suggests that it"s been around for twice as long as believed
Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models. These models estimate the universe to be 13.8 billion years in age, based on the big-bang expanding universe concept......»»
New type of visible-light responsive photocatalyst is efficient, stable and very economical
Researchers at the University of Johannesburg have developed a new type of photocatalyst that harnesses the visible portion of the sunlight spectrum. Currently, economical and environmentally-friendly photocatalysts only 'use' the UV spectrum of sunl.....»»
SARS-CoV-2: How the history of human populations influences their immune response
During the COVID-19 pandemic, the clinical spectrum observed among people infected with SARS-CoV-2 ranged from asymptomatic carriage to death. Researchers at the Institut Pasteur, the CNRS and the Collège de France, in collaboration with researchers.....»»
TESS has found thousands of possible exoplanets: Which ones should JWST study?
There are more than 5,000 confirmed exoplanets in our galaxy. That number is going to rise significantly in the next decade. The Transiting Exoplanet Survey Satellite (TESS) has already cataloged more than 4,000 candidate exoplanets, and the PLAnetar.....»»
Greenhouse gases are changing air flow over the Pacific Ocean, raising Australia"s risks of extreme weather
After a rare three-year La Niña event brought heavy rain and flooding to eastern Australia in 2020-22, we're now bracing for the heat and drought of El Niño at the opposite end of the spectrum......»»
Researchers suggest the most compelling places to search for life will look like "anomalies"
In the past two and a half years, two next-generation telescopes have been sent to space: NASA's James Webb Space Telescope (JWST) and the ESA's Euclid Observatory. Before the decade is over, they will be joined by NASA's Nancy Grace Roman Space Tele.....»»
AT&T Customers Also Getting C-Band Speed Boost
Earlier in the week, Verizon announced that customer 5G UWB data speeds would see an increase thanks to full access to the total amount of 5G C-band spectrum it bought back in 2021. Following that news, AT&T has confirmed the exact same, meaning more.....»»

Competition for food? Jaw analyses show what cave bears and brown bears ate
The differences are in the details: Special 3D shape analyses of the jaws and dentitions of cave bears and brown bears living at the same time from the fossil site in the caves of Goyet in Belgium show their clearly different food spectrum......»»
New low-mass quiescent galaxy discovered
By analyzing the data from the JWST Advanced Deep Extragalactic Survey (JADES), an international team of astronomers has discovered a new quiescent galaxy. The newfound system, designated JADES-GS+53.12365-27.80454, turns out to be the least massive.....»»
