While a Mars rover can explore where no person has gone before, a smaller robot at the University of the Sunshine Coast in Australia could climb to new heights by mimicking the movements of a lizard.

Simply named X-4, the university’s climbing has allowed a team of researchers to test and replicate how a lizard moves in the hope that their findings will inspire next-generation robotics design for disaster relief, remote surveillance and possibly even space exploration.

In a published today in Proceedings of the Royal Society B, the team states that have optimized their movement across difficult terrain over many years of evolution.

Access to clean water is a huge issue across the globe. Even in areas with water resources, a lack of infrastructure or reliable energy means purifying that water is sometimes extremely difficult.

That’s why a vapor designed by University at Buffalo and University of Wisconsin-Madison engineers could be revolutionary. Unlike other radiative vapor condensers which can only operate at night, the new design works in direct sunlight and requires no energy input.

“We have worked on solar-driven water evaporation technologies in the past years,” says Qiaoqiang Gan, Ph.D., professor of electrical engineering at UB and a leading corresponding author. “We are now addressing the second half of the water cycle, condensation.”

Data affecting more than 500 million Facebook users that was originally leaked in 2019, including email addresses and phone numbers, has been posted on an online hackers forum, according to media reports and a cybercrime expert.

“All 533000, 000 Facebook records were just leaked for free,” Alon Gal, at the Hudson Rock cybercrime intelligence firm, said Saturday on Twitter.

He denounced what he called the “absolute negligence” of Facebook.

Robot swarms have, to date, been constructed from artificial materials. Motile biological constructs have been created from muscle cells grown on precisely shaped scaffolds. However, the exploitation of emergent self-organization and functional plasticity into a self-directed living machine has remained a major challenge. We report here a method for generation of in vitro biological robots from frog (Xenopus laevis) cells. These xenobots exhibit coordinated locomotion via cilia present on their surface. These cilia arise through normal tissue patterning and do not require complicated construction methods or genomic editing, making production amenable to high-throughput projects.

Google has announced an update to its Developer Program Policy that will help to prevent applications from viewing which other apps are installed on an Android device. The company states that they consider installed apps to be private user information and therefore, aim to protect Android users by keeping this data secure.

That is to say, Google will limit which apps can request the QUERY_ALL_PACKAGES permission, presently mandatory for application targeting API level 30 (Android 11) and above that wish to query the list of application a user has installed for an Android 11 or later .

From now on, the QUERY_ALL_PACKAGES permission will only be available when the core functionality of an app in question must query any of the device’s installed applications. Therefore, in order to dispute this , developers will have to provide reasonable evidence for how querying the API of an Android devices installed applications is absolutely necessary in order for that device to properly function.

Michio Kaku is a professor of theoretical physics at City College, New York, a proponent of string theory but also a well-known populariser of science, with multiple TV appearances and several bestselling books behind him. His latest book, The God Equation, is a clear and accessible examination of the quest to combine Einstein’s general relativity with quantum theory to create an all-encompassing “theory of everything” about the nature of the universe.

The physicist on Newton finding inspiration amid the great plague, how the multiverse can unite religions, and why a ‘theory of everything’ is within our grasp.

Astronomers have announced the Uranus, the seventh planet from the Sun, is an ice giant planet in the outer Solar System. Like Jupiter and Saturn, Uranus and its rings appear to mainly produce X-rays by scattering solar X-rays, but some may also come from.

Astronomers have detected X-rays from Uranus for the first time, using NASA ’s Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.

Uranus is the seventh planet from the Sun and has two sets of rings around its equator. The planet, which has four times the diameter of Earth, rotates on its side, making it different from all other planets in the solar system. Since Voyager 2 was the only spacecraft to ever fly by Uranus, astronomers currently rely on telescopes much closer to Earth, like Chandra and the Hubble Space Telescope, to learn about this distant and cold planet that is made up almost entirely of hydrogen and helium.
