From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years. But the ice sheet can be thousands of meters deep at its thickest, and it hides hundreds of meltwater lakes where its base meets the continent’s bedrock. Deep below the surface, some of these lakes fill and drain continuously through a system of waterways that eventually drain into the ocean.

Now, with the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have improved their maps of these hidden lake systems under the West Antarctic ice sheet—and discovered two more of these active subglacial lakes.

The new study provides critical insight for spotting new subglacial lakes from space, as well as for assessing how this hidden plumbing system influences the speed at which ice slips into the Southern Ocean, adding freshwater that may alter its circulation and ecosystems.

Methane at Enceladus: biotic or abiotic origin?

Here we go again: biology or unknown abiotic process?

Physicists have verified a key prediction of Albert Einstein’s special theory of relativity with unprecedented accuracy. Experiments at a particle accelerator in Germany confirm that time moves slower for a moving clock than for a stationary one.

The work is the most stringent test yet of this ‘time-dilation’ effect, which Einstein predicted. One of the consequences of this effect is that a person travelling in a high-speed rocket would age more slowly than people back on Earth.

Hexagonal boron nitride (h-BN) is officially the iron man of two-dimensional materials, beating graphene in toughness by 10 times.

These spring-loaded screws turn your entire drywall into a sound deadening structure that can reduce perceived noise levels by nearly half. They’re pricey for screws, says the Swedish scientist behind them, but very cheap for sound insulation. Known as the Revolutionary Sound Absorbing Screw (or the Sound Screw for short), the device was created by a team at Malmö University, led by senior lecturer Håkan Wernersson. It consists of a threaded section at the bottom, a coil spring in the middle, and a section with a flat head at the top.

Nobody likes hearing their neighbors’ music, TV shows or loud conversations. Soundproof wall materials, however, can be quite thick and expensive. Swedish scientists have developed a thinner, less costly alternative, in the form of a spring-loaded sound-damping screw.

The US Defense Advanced Research Projects Agency (DARPA) has selected three teams of researchers led by Raytheon, BAE Systems, and Northrop Grumman to develop event-based infrared (IR) camera technologies under the Fast Event-based Neuromorphic Camera and Electronics (FENCE) program. It is designed to make computer vision cameras more efficient by mimicking how the human brain processes information. DARPA’s FENCE program aims to develop a new class of low-latency, low-power, event-based infrared focal plane array (FPA) and digital signal processing (DSP) and machine learning (ML) algorithms. The development of these neuromorphic camera technologies will enable intelligent sensors that can handle more dynamic scenes and aid future military applications.

New intelligent event-based — or neuromorphic — cameras can handle more dynamic scenes.

A new DIY robot called PetBot is a unique development that will help to recycle ordinary plastic bottles. The process is not yet fully automated, and the device does not claim to be used for commercial purposes, but the benefits of its operation are obvious. Built by JRT3D, the PetBot automates the plastic recycling process by cutting PET bottles into the tape and then turning them into filament. The robot combines several mechanics, each of which performs its part of the task. It carries out the two separate processes at the same time using the same stepper motor.

AI taking over voice acting is just the beginning. Why cant the AI render and generate the game world all by itself. Why cant it generate the models, and actors for the game from scratch; and then use deepfake type animation to animate characters. And, then write an original script for the story. These things are all possible now. Only a matter of time before someone has the idea to put it all together.

Voice actors are rallying behind Bev Standing, who is alleging that TikTok acquired and replicated her voice using AI without her knowledge.
