Pattern of brain damage is pervasive in Navy SEALs who died by suicide
David Metcalf’s last act in life was an attempt to send a message — that years as a Navy SEAL had left his brain so damaged that he could barely recognize himself. He died by suicide in his garage in North Carolina in 2019, after nearly 20 years in the Navy. But just before he […]
How the 1904 Marathon Became One of the Weirdest Olympic Events of All Time
Karen Abbott; Updated by Ellen Wexler America’s first Olympics may have been its worst, or at least its most bizarre. Held in 1904 in St. Louis, the games were tied to that year’s World’s Fair, which celebrated the centennial of the Louisiana Purchase while advancing, as did all such turn-of-the-century expositions, the notion of American imperialism. Although there […]

The cutest monopoly: Koala Kare
In the age of antitrust, why has Koala Kare, Big Baby Change Station, flown under the radar?
An Analog Network of Resistors Promises Machine Learning Without a Processor
Researchers from the University of Pennsylvania have come up with an interesting approach to machine learning that could help to address the field’s ever-growing power demands: taking the processor out of the picture and working directly on an analog network of resistors. “Standard deep learning algorithms require differentiating large non-linear networks, a process that is […]
Duff’s Device and Coroutines (2008)
At first glance, Duff’s Device is one of the most mysterious pieces of C code you’ll ever see: void send(short *to, short *from, int count) { int n=(count+7)/8; switch(count%8){ case 0: do{ *to = *from++; case 7: *to = *from++; case 6: *to = *from++; case 5: *to = *from++; case 4: *to = *from++; case 3: *to = *from++; case 2: *to = *from++; case 1: *to = *from++; }while(–n>0); } } It’s an 8x-unrolled while loop interlaced with a switch statement. The switch jumps into the middle of the while loop to […]
Anti-aging molecule successfully restores multiple markers of youth
In pre-clinical trials, a small molecule effectively regrew neurons, reduced inflammation, and improved memory, speed, coordination, grip strength, and more. The finding could have a profound impact on aging and the diseases that accompany it. In conducting the research, scientists at the University of Texas MD Anderson Cancer Center, turned their focus to telomerase reverse […]
An unexpected journey into Microsoft Defender’s signature World
Introduction Microsoft Defender is the endpoint security solution preinstalled on every Windows machine since Windows 7. It’s a fairly complex piece of software, addressing both EDR and EPP use cases. As such, Microsoft markets two different products. Microsoft Defender for Endpoint is a cloud based endpoint security solution that combines sensor capabilities with the advantages […]
Weekend projects: getting silly with C
C is beautiful yet full of horrors. Here’s to uncovering its hidden depths. For all its warts, the C language is a marvelous thing. It is remarkably simple, yet somehow expressive enough to allow entire operating systems to be written with ease. Just as curiously, its terse, minimalistic syntax became the way to structure code […]
NASA rover discovers mysterious Mars boulder unlike any others
If looking at this Mars vista conjures up childhood memories of the song, “One of these things is not like the others,” NASA scientists are right there with you. Perseverance, a car-size lab on six wheels, traveled into the Red Planet’s Neretva Vallis last week. Though this region may look like a barren desert, it […]
