Watch the moment OSIRIS-REx tagged an asteroid to collect samples

On Tuesday this week, NASA’s OSIRIS-REx spacecraft briefly touched down on the surface of asteroid Bennu to snatch a sample of the ancient pristine rock, and took off again. And now NASA has released images and video from the robot’s perspective.Contin… Continue reading Watch the moment OSIRIS-REx tagged an asteroid to collect samples

Super-white paint reflects 95.5 percent of sunlight to cool buildings

Researchers from Purdue University have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the ambient temperature. Painted on a building, the new paint could help cut cooling costs and … Continue reading Super-white paint reflects 95.5 percent of sunlight to cool buildings

Smart windows darken and become solar cells when heated

Windows are great for letting in light, but in summer months that comes with an unwanted side order of heat, causing many people to run the air conditioning non-stop. Now, researchers have developed windows that can change color automatically when heat… Continue reading Smart windows darken and become solar cells when heated

Ancient tectonic plate discovered beneath Canada, geologists claim

The face of the Earth has changed drastically over its life, with plates shifting and sinking. Now, geologists at the University of Houston claim to have found the remains of an ancient tectonic plate beneath Canada that was pushed under the surface te… Continue reading Ancient tectonic plate discovered beneath Canada, geologists claim

Calcium nanoparticles could help knock out cancer’s drug resistance

Chemotherapy remains one of our best treatments against cancer but, frustratingly, cancer cells can develop resistance to these drugs. Now, researchers at Zhengzhou University have found that bursts of calcium can weaken their defense mechanism from th… Continue reading Calcium nanoparticles could help knock out cancer’s drug resistance

LG’s rollable OLED TV finally hits the market at eye-watering price

LG has been talking about a huge rollable TV for more than two years now – and it’s finally about to hit the market. The LG Signature OLED R has a screen that can be rolled into a box when not needed, plus all the visual bells and whistles you’d expect… Continue reading LG’s rollable OLED TV finally hits the market at eye-watering price

Cells found to use toxic fat droplets to fight infection

Fat is best known for being an energy storage system, but now researchers have discovered that it plays a previously unknown role in defense against infection. A team from the Universities of Queensland and Barcelona found that cells can use fats to fi… Continue reading Cells found to use toxic fat droplets to fight infection

Betelgeuse is closer to Earth and further from exploding than we thought

The star Betelgeuse has been a bit of a drama queen lately, dimming twice in the past year. Now astronomers say they’ve found what may have caused the latest episode – and in so doing, also discovered that the star is smaller, closer to Earth and furth… Continue reading Betelgeuse is closer to Earth and further from exploding than we thought

Proposed dark matter detector watches a billion tiny pendulums swing

Despite hunting for it for decades, scientists have so far been unable to detect any definitive signs of dark matter. But a new detector design, using an array of billions of tiny pendulums, could finally break the silence by searching for the effects … Continue reading Proposed dark matter detector watches a billion tiny pendulums swing

Shortest event ever measured lasts mere sextillionths of a second

Physicists in Germany have measured the shortest timespan ever recorded. The team measured the time it takes for a photon of light to travel the length of a hydrogen molecule, and found it to occur in just trillionths of a billionth of a second.Continu… Continue reading Shortest event ever measured lasts mere sextillionths of a second
