An authentic career strategy built around sustainability involves embedding these key principles into all jobs, argues Marilyn Waite.
Three images of the Ring Nebula reveal its true shape: visible light (left), infrared (center), and a composite with contour lines (right) showcasing different details of the nebula's intricate structure.
The Ring Nebula, a bright, circular planetary nebula, is created by a dying Sun-like star. After centuries, we finally know its true shape.

Dubbed "Valeriana" by researchers, the city of 50,000 peaked around 800 AD before being swallowed by the jungle.
A collage of images shows microscopic views with arrows and lines depicting movement and velocity, displayed on a color scale, with a scale marker indicating 20 micrometers.
Motility was suggested as a promising "biosignature" as early as the 1960s, but the technology was insufficient — until now.
JWST MIRI NIRCam SMACS 0723
Since mid-2022, JWST has been showing us how the Universe grows up, from planets to galaxies and more. So, what's its biggest find of all?
An abstract geometric pattern of spirals and interlocking squares in white on a black grid background evokes the elegant precision often found at the intersection of mathematics and science.
Physicist Don Lincoln explains why mathematics is a powerful tool for scientific modeling, but is not a science itself.
proton internal structure
A proton is the only stable example of a particle composed of three quarks. But inside the proton, gluons, not quarks, dominate.
Two people in hoodies are seen from above, interacting clandestinely with a smartphone, oblivious to potential smartphone bans.
In many ways, the rising anti-phone fervor in schools mirrors moral panics of the past.

"There is so much more uncertainty and volatility in a world that is moving fast with big countries that are more at odds with each other and with fewer rules of the road that leaders, companies, and societies are adhering to."
Six mesmerizing images, bathed in red hues, reveal distant galaxies—JWST's little red dots. Each is precisely labeled: CEERS 14448, NGDEEP 4321, PRIMER-COS 10539, CEERS 20320, JADES 9186, and PRIMER-UDS 17818—alongside their corresponding redshift values.
The discovery of ultra-bright, ultra-distant galaxies was JWST's first big surprise. They didn't "break the Universe," and now we know why.
A classical statue covers its face with a hand on the left. On the right, a butterfly sits on a surface with text beneath it.
Today's philosophy students would be justified in asking, "What does any of this have to do with living?"
A supermassive black hole caught turning on reveals a mesmerizing cosmic dance, with bright streams of light and colorful gases swirling around it against a starry backdrop.
Seven years ago, an outburst in a distant galaxy brightened and faded away. Afterward, a new supermassive black hole jet emerged, but how?
A grayscale portrait of a man with short hair, wearing a collared shirt, is framed within a colorful, abstract background that symbolizes progress with less reliance on cellphones.
Yondr CEO Graham Dugoni unpacks the technological zeitgeist in this exclusive Big Think interview covering media ecology, leadership, AI, human connection, and much more.
A vibrant cosmic scene reveals a galaxy with bright jets of energy, hottest stars twinkling vividly amidst scattered stars against a dark backdrop.
Here in our Universe, stars shine brightly, providing light and heat to planets, moons, and more. But some objects get even hotter, by far.
A digitally altered image blending the flags of China and the United States with pixelated and abstract effects, symbolizing a modern digital cold war.
“Technology has always been co-opted for war, but truly intelligent AI, let alone a superintelligence, is a different beast entirely.”
A gloved hand holds a smoking test tube with tongs against a dark background.
Other plans for the tech: organ banking and deep space travel.
A bright star emits light in a field of smaller, scattered stars against a dark sky.
Most stars shine with properties, like brightness, that barely change at all with time. The ones that do vary help us unlock the Universe.
A person holds a sign reading "GLOBAL WARMING is a cruel hoax" with a dog standing nearby on a leafy ground.
Astronomer Adam Frank reflects on some responses to his recent appearance on the Lex Fridman Podcast.
Diagram of particle interactions with wavy and straight lines, illustrating how photons mediate attraction and repulsion in various Feynman diagrams in particle physics.
The electromagnetic force can be attractive, repulsive, or "bendy," but is always mediated by the photon. How does one particle do it all?
Black and white abstract design featuring swirling, concentric patterns resembling a ripple effect with a yin-yang-like motif at the center.
Despite no experimental evidence showing that gravitons exist, they remain a respectable concept in the world of professional physicists.
