Mars helicopter Ingenuity checks in from the red planet
NASA's Jet Propulsion Laboratory has shared the first update from Ingenuity, the helicopter which landed on Mars along with the Perseverance rover this week......»»
Mars analog stations investigate lichen biodiversity during simulated missions
Once you know where to look for them, lichens are everywhere. These composite organisms—fungal and photosynthetic partners joined into a greater whole—can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. The.....»»
Finely regulated luminescent Ag-In-Ga-S quantum dots with green-red dual emission toward white LEDs
Semiconductor quantum dots (QDs) materials have shown great potential for applications in lighting and display fields due to their wide color gamut, adjustable emission wavelength, high quantum efficiency, high color saturation, and low processing co.....»»
Wildlife loss is taking ecosystems nearer to collapse, new report suggests
Even for a conservation biologist numbed to bad news about nature, the biennial Living Planet report from the World Wildlife Fund (WWF) is a stark reminder of our failure to arrest the loss of biodiversity—the variety of living things and the ecosy.....»»
Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
In our opinion: Believe the storms: Climate change is real
No one should try to kill the auto industry in hopes of saving the planet. But we must also take seriously the need for the industry to be a functional partner in a solution......»»
Red milkweed beetle genome offers evolutionary insights into plant-insect interactions
Studying the secrets of how the common red milkweed beetle can safely feed on a toxic plant helps illuminate the ecological, evolutionary and economic impact of insect-plant interactions from a genomic perspective......»»
How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues
Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds or perhaps even thousands of kilometers......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
Hubble and New Horizons offer dual perspectives on Uranus to inform exoplanet research
NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study l.....»»
James Webb discovers a new type of exoplanet: an exotic ‘steam world’
Researchers using James Webb have identified a new and exotic type of planet called a steam world, with an atmosphere almost entirely composed of water vapor......»»
How academia drives sustainability: The impact of science on the UN"s Sustainable Development Goals
The role of universities in the fight for a fairer and more sustainable planet is increasingly significant. A team of researchers from ESPOL has examined how academia contributes to the UN's Sustainable Development Goals (SDGs) by analyzing scientifi.....»»
New insights into bubble interference could enhance electrode design
Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage red.....»»
BreachLock Attack Surface Analytics strengthens enterprise CTEM capabilities
BreachLock strengthens continuous threat exposure management (CTEM) capabilities for enterprise customers with its new Attack Surface Analytics feature. Time is of the essence when Fortune 500 security teams find themselves waking up to a Code Red vu.....»»
The other greenhouse gases warming the planet
While carbon dioxide, or CO2, is the best known greenhouse gas, several others, including methane and nitrous oxide, are also driving global warming and altering the Earth's climate......»»
Research suggests Earth"s oldest continental crust is disintegrating
Earth's continental configurations have changed dramatically over its billions of years' history, transforming not only their positions across the planet, but also their topography as expansion and contraction of the crust made a mark on the landscap.....»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
New study eases concerns over possible "doomsday" asteroid swarm
Astronomers have good news about potentially hazardous asteroids lurking near our planet: There aren't as many as we thought......»»
Curiosity rover provides new insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life—with evidence for widespread liquid water on the surface—to a surface that is.....»»
Nuclear rockets could travel to Mars in half the time, but designing the reactors that would power them isn"t easy
NASA plans to send crewed missions to Mars over the next decade—but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip......»»
