Imagine being so greedy that you’re willing to sue someone because they aren’t as greedy as you.

Li and his colleagues found that the animals’ social ranking in the group was closely linked to the results of competition, and by examining recordings from neurons in the brains of mice in real time, the team discovered that neurons in the anterior cingulate region of the brain store this social ranking information to inform upcoming decisions.
“Collectively, these neurons held remarkably detailed representations of the group’s behavior and their dynamics as the animals competed together for food, in addition to information about the resources available and the outcome of their past interactions,” explains senior author Ziv M. Williams, MD, a neurosurgical oncologist at MGH. “Together, these neurons could even predict the animal’s own future success well before competition onset, meaning that they likely drove the animals’ competitive behavior based on whom they interacted with.”
Manipulating the activity of these neurons, on the other hand, could artificially increase or decrease an animal’s competitive effort and therefore control their ability to successfully compete against others. “In other words, we could tune up and down the animal’s competitive drive and do so selectively without affecting other aspects of their behavior such as simple speed or motivation,” says Williams.
To develop the hypersonic vehicles of the future, we need to properly understand how to predict boundary layer transition on realistic vehicle shapes and what the minute effects of turbulent flow on hypersonic vehicles are. Data from the BOLT II flight experiment will help do just that.
Both the BOLT and BOLT II vehicles have a complex, swept geometry with a concave surface to represent a real hypersonic vehicle. The aim is to produce complex, real-world data that engineers and scientists can use to improve their models for predicting transition on hypersonic vehicles.
A separate experiment is run on each side of the vehicle, with one “smooth” side and one “rough” side. The flow running length along the vehicle is 1 meter, slightly larger than the original BOLT vehicle.
BOLT II will be launched on a suborbital trajectory by a two-stage sounding rocket. During its ascent, it is planned to reach Mach 6, where an ascent flight experiment will occur. It will turn over in space and then re-enter the atmosphere, before performing a descent experiment at Mach 5.5.
Microsoft (MSFT) has confirmed it was breached by the hacker group Lapsus$, adding to the cyber gang’s growing list of victims.
In a blog post late Tuesday, Microsoft said Lapsus$ had compromised one of its accounts, resulting in “limited access” to company systems but not the data of any Microsoft customers.
Twenty Two Motors. Fifty gears. Eighty Two Hundred RPM. Hundreds of individual pieces, and one sheet of glossy paper cut into a disk. This isn’t a nightmare driven Rube Goldberg machine. Instead, it’s a Lego monstrosity created by [GazR] of [GazR’s Extreme Brick Machines!], and all of these parts are flying in formation for one Lego slicing purpose. In the video below the break, you can see what very well may be the worlds most powerful Lego and Paper table saw.
Starting out with a build that had a mere fourteen motors in a platform that looked quite a lot more like a table saw, [GazR] learned that having only fourteen motors turning a Lego based blade was not a good combination. In the next iteration, the same number of motors were used, but the gearing was increased to bring RPM up, and a Lego toy saw blade took care of cutting duties.
Seeing that higher speeds with thinner blades was a winning trend, [GazR] stepped it up to the aforementioned 8,200 RPM twenty-two motored paper whirling Lego Death Machine. Yes, [GazR] cut Lego, carrots, carpet, and paper-all with circular sheet of paper.
PC power supplies haven’t seen a whole lot of change in the last decade or two. We’ve gotten modular cables for easier routing, smaller standards for itty-bitty builds, and that’s about it. But today Intel has finalized the ATX 3.0 standard, coming soon to a full-sized PC case near you. The biggest addition announced today is a new standardized connection for graphics cards and other PCIe devices, delivering up to 600 watts on a single connector.
Currently graphics cards are in a bit of a power pinch. The maximum throughput for an 8-pin ATX rail is 150 watts, so the biggest and most power-hungry GPUs need to double or even triple up, adding extra space requirements and more complex cable routing inside the case. The new 12-pin 12VHPWR connection should be able to deliver more energy than even the most powerful graphics cards need for the next generation or two. Each pin housing is also physically smaller, with a 3.0mm pitch versus 4.2mm on current power supply rails.
Technically it’s 16 total pins (12+4), with four additional data pins squeezed in beneath the primary power pins. This is to manage DC output voltage regulation and a series of new tools designed to regulate high power output efficiently and safely, all handled intelligently by the power supply. According to Intel, the new 12VHPWR connection will be the standard for “most, if not all” PCIe cards using the 5.0 spec.
