The world needs to dig up far more minerals to meet climate goals. But mining poses environmental dangers that are bitterly dividing communities.
A new study found that, out of 180 apps examined, 45 collect photos, and 12 gather videos — and most of these apps belong to top apparel giants.
Color mixing is the process of combining two or more colors: red and green make yellow, blue and red make purple, red and green and blue make white. This process of mixing colors is the basis for the future of solid-state lighting. While currently white light is achieved by phosphor down-conversion, LED color mixing actually has a higher theoretical maximum efficiency, which is needed in order to achieve the 2035 DOE energy efficiency goals.
Despite the potential efficiency of color-mixed LED sources, there exists one significant challenge: green. The “green gap” is described as the lack of suitable green LEDs. Current green LEDs are made from state-of-the-art hexagonal III-nitride but only reach one third of the efficiency goals laid out in the 2035 DOE roadmap.
In a new study, researchers at the University of Illinois Urbana-Champaign have found a potential path to fill the green gap and report a green-emitting cubic III-nitride active layer with 32% internal quantum efficiency (IQE), which is more than 6 times higher efficiency than what is reported in the literature for conventional cubic active layers.
Microscopic water bears can enter a near-invincible ‘tun’ state when stressed, enabling them to survive in the harshest conditions — including the vacuum of space. Now we know how.
In this clip from our 2017 event titled ‘Evolution of the Mind, Consciousness and AI,’ the esteemed philosopher and cognitive scientist, Daniel Dennett is joined by a group of panellists to explore how much we understand about the human mind, and what the creation of artificial consciousness means for our future. Watch and let us know in the comments if you think Dennett’s theories still hold true in light of the rapid developments in AI since he joined us.
See the full session here: • Daniel Dennett on the Evolution of th…

The first vertical takeoff and landing test (VTVL) for the Zhuque-3 reusable methane-powered carrier rocket was successfully conducted in the Gobi Desert in northwestern China on Friday afternoon, according to its developer LandSpace, a Chinese commercial aerospace company.
The company said that the test flight lasted for about 60 seconds, with the trial rocket reaching a height of approximately 350 meters above the ground. The rocket landed 100 meters away from the liftoff point with a precision of about 2.4 meters.
The company said that the full-sized trial rocket prototype verified the key technologies for the first stage of Zhuque-3, which is set to be launched in 2025. These technologies include variable-thrust technology with a wide range and landing guidance and control.
