Martian Surprise: NASA’s Perseverance Makes New Discoveries in Mars’ Jezero Crater

Using its WATSON camera, NASA’s Perseverance Mars rover took this selfie over a rock nicknamed “Rochette,” on September 10, 2021, the 198th Martian day, or sol, of the mission. Two holes can be seen where the rover used its robotic arm to drill rock core samples. Credit: NASA/JPL-Caltech/MSSS The Mars rover found that Jezero Crater’s …

Possible 'Ocean World' Discovered 100 Light-Years Away From Earth

Potential ‘Ocean World’ Discovered 100 Light-Years Away From Earth

The job of NASA’s Transiting Exoplanet Survey Satellite is simply surreal. Imagine traveling a thousand years back in time and then explaining to someone how future scientists will have a machine that detects alien worlds floating at distances beyond the capacity of human imagination.  That’s TESS. Since 2018, this space-borne instrument has literally found thousands …

NASA's Webb telescope captures first evidence of carbon dioxide on an exoplanet

NASA’s Webb telescope captures first evidence of carbon dioxide on an exoplanet

The exoplanet, WASP-39b, is a hot gas giant orbiting a sunlike star that is 700 light-years from Earth and part of a larger Webb investigation that includes two other transiting planets, according to NASA. Understanding the atmospheric makeup of planets like WASP-39b is critical for knowing their origins and how they evolved, the agency noted …

Turning Cancer Cells Into Normal Cells

Cancer of the body’s blood-forming tissues, such as the lymphatic system and bone marrow, is known as leukemia. A mechanism is discovered that explains how cancer cells transform into normal, harmless ones. A recent study explains how changing the chemical modifications, or so-called epigenetics, of a specific type of leukemia cell’s genetic material, the messenger

Lab-made mouse embryos grew brains and beating hearts, just like the real thing

Scientists coaxed mouse stem cells to grow into synthetic embryos that began developing hearts and brains, just like the real thing. The lab-made embryos, crafted without any eggs or sperm and incubated in a device that resembles a fast-spinning Ferris wheel full of tiny glass vials, survived for 8.5 days. That’s nearly half the length …

‘Levitating’ nanoparticles could push the limits of quantum entanglement

Particles of glass suspended in laser beams can be made to interact (artist’s impression).Credit: Equinox Graphics Ltd. Physicists have suspended tiny glass spheres in a vacuum and made them interact with one another at close distance. The ‘levitating’ nanoparticles have now been manipulated with enough precision to open new ways of probing the enigmatic twilight …

Rock-hunting NASA rover reveals Martian crater's surprising geology

Rock-hunting NASA rover reveals Martian crater’s surprising geology

By Will Dunham WASHINGTON (Reuters) – Core samples drilled by NASA’s Perseverance rover on the Martian surface are revealing the geology of a gaping crater scientists suspect may have harbored microbial life billions of years ago, including surprises about the nature of the rock present there. The samples, obtained by the car-sized, six-wheeled robotic rover …

Physicists develop a perfect light trap

Physicists develop a perfect light trap

The “light trap” setup is shown, consisting of a partially transparent mirror, a thin, weak absorber, two converging lenses and a totally reflecting mirror. Normally, most of the incident light beam would be reflected. However, due to precisely calculated interference effects, the incident light beam interferes with the light beam reflected back between the mirrors, …

Obesity Weight Loss Concept

Newly Identified Molecule Can Burn Body Fat

The researchers believe that their discovery could one day be used as a treatment for obesity. Researchers have discovered a new signaling molecule that forces brown fat cells to consume more energy. Typically, fat cells store energy. However, energy is lost as heat in brown fat cells, making brown fat a biological heater. This mechanism is consequently …
