A new photo of Magic Leap 2 appears to show the device’s controller equipped with cameras for inside-out tracking which would be the first time we’ve seen the approach employed in a commercial XR headset.

Though we learned plenty of interesting details about the forthcoming Magic Leap 2 AR headset back in January, it looks like there’s still some secrets left to uncover.

A recent photo of Magic Leap 2 posted by Peter H. Diamandis is, as far as we know, the first time we’ve gotten a clear look at the front of the Magic Leap 2 controller. The photo clearly shows what appear to be two camera sensors on the controller, indicating a high likelihood it will have on-board inside-out tracking.

Drugs are polluting rivers and adding to the resistance crisis as well as affecting riverine ecosystems.

Pharmaceutical pollution in the world’s rivers is threatening environmental and human health and the attainment of UN goals on water quality, with developing countries the worst affected, a global study warns.

Active pharmaceutical ingredients (APIs) could be contributing to antimicrobial resistance in microorganisms, and may have unknown long-term effects on human health, as well as harming aquatic life, according to the report published in Proceedings of the National Academy of Sciences.

APIs – the chemicals used to make pharmaceutical drugs – can reach the natural environment during their manufacture, use and disposal, according to the study.

Using corn for fuel seems like a dumb idea in light of new research.

Ethanol makes up 10% of most of the gasoline sold in the United States. A large part of why Ethanol is so prevalent is that the Renewable Fuel Standard, created in 2005, wanted to reduce the emissions of the fuels we use. Ethanol created from corn is renewable, because the corn takes carbon from the atmosphere to grow, creating a cycle that minimizes how much carbon is added to the atmosphere. At least, that’s the story we were told.

New research out of University of Wisconsin — Madison, suggests that “the carbon intensity of corn ethanol is no less than gasoline and likely at least 24% higher.” What’s the solution? We need to choose options that have a greater percentage of net emissions reductions, so that we don’t unintentionally increase emissions if regulators estimated predictions are incorrect.

A nuclear reactor at an Illinois energy plant is helping University of Chicago scientists learn how to catch and understand the tiny, elusive particles known as neutrinos.

At Constellation’s (formerly Exelon) Dresden Generating Station in Morris, Illinois, the team took the first measurements of coming off a with a tiny detector. These particles are extremely hard to catch because they interact so rarely with matter, but power reactors are one of the few places on Earth with a high concentration of them.

“This was an exciting opportunity to benefit from the enormous neutrino production from a reactor, but also a challenge in the noisy industrial environment right next to a reactor,” said Prof. Juan Collar, a particle physicist who led the research. “This is the closest that neutrino physicists have been able to get to a commercial reactor core. We gained unique experience in operating a detector under these conditions, thanks to Constellation’s generosity in accommodating our experiment.”

A good article on how to understand peer review and its importance in the advancement of science.

Peer review is the lifeblood of good science. But understanding the process can take time, and gaining review experience can be daunting. Marc Gillett explains the key elements of this critical component of science.

Early career research.

Research management.

An experimental new type of cancer treatment has yielded some impressive results in mice: the eradication of advanced-stage ovarian and colorectal cancer in the animals as little as six days.

The new therapy has only been tested in mice so far, so let’s not get too excited just yet. However, the early signs are promising, and human clinical trials could be underway by the end of the year.

The treatment involves tiny ‘drug factory’ beads that are implanted into the body and deliver a continuous, high dose of interleukin-2 (IL2) – a natural compound that enlists white blood cells in the fight against cancer.

Mozilla has pushed out-of-band software updates to its Firefox web browser to contain two high-impact security vulnerabilities, both of which it says are being actively exploited in the wild.

Tracked as CVE-2022–26485 and CVE-2022–26486, the zero-day flaws have been described as use-after-free issues impacting the Extensible Stylesheet Language Transformations (XSLT) parameter processing and the WebGPU inter-process communication (IPC) Framework.

Details have emerged about a now-patched high-severity vulnerability in the Linux kernel that could potentially be abused to escape a container in order to execute arbitrary commands on the container host.

The shortcoming resides in a Linux kernel feature called control groups, also referred to as cgroups version 1 (v1), which allows processes to be organized into hierarchical groups, thereby making it possible to limit and monitor the usage of resources such as CPU, memory, disk I/O, and network.

Tracked as CVE-2022–0492 (CVSS score: 7.0), the issue concerns a case of privilege escalation in the cgroups v1 release_agent functionality, a script that’s executed following the termination of any process in the cgroup.
