Hashima Hasan is a highly accredited NASA program scientist and the first female program scientist for the James Webb Space Telescope. Read her inspirational journey and career highlights from NASA!

The story starts in October 1957, when I was 7 years old, and my grandmother ordered the entire family, including my 3-year-old sister, all the servants and their families, to collect at dawn in the backyard of the home and watch Sputnik pass by the clear night skies of Lucknow.

That morning, as I saw Sputnik and the dark, starry sky, I dreamt the impossible dream that one day I would be a space scientist. The path was not easy. With determination and encouragement from my mother and school teachers, I forged ahead, won a scholarship to the University of Oxford, from where I earned a doctorate in theoretical nuclear physics in 1976. The path to a traditional academic career for a female scientist was fraught with challenges, exacerbated by social pressures. After pursuing post-doctoral research, a university faculty position, crisscrossing three continents and making a home across the Atlantic three times, I found myself again on the shores of the U.S. (1985) ― this time with a husband and two infant sons.

If you are in NYC you have tromped over your fair share of questionable snow piles. The dumping the east coast got in January followed by an extended Arctic plunge gave these mountains time to accumulate some…extra bits. The grey-black blobs are about as unsanitary as they look – full of bacteria and heavy metals.

All the more reason to breathe a cautious sigh of relief as glaciers of grossness finally begin to recede.

Gothamist sampled 3 different sites to test for bacteria and metals. Ultimately the snow is just a reflection of what is already part of the city environment; so good hygienic practices should always be observed.

“It really teaches us a lesson about urban sanitation and health,” said Jack Caravanos, an environmental public health professor at NYU. He added that the snow poses no greater risk to public health than what’s always in New York City’s air and in the ground — as long as you leave it alone.

Our Jackson Heights sample also contained the highest concentration of Enterococcus, a type of bacteria found in the feces of warm-blooded animals like dogs or, God forbid, humans. You’ve also likely noticed a preponderance of poop on the snow-covered sidewalks.

Researchers at McMaster University collected sleep and activity data from 93 adults across Canada who had previously recovered from depression. Utilizing a research-grade actigraphy wearable device, over 32,000 days of data was generated. Their research was published in JAMA Psychiatry.

The new research highlights a simple, yet powerful way to passively monitor relapse risk in people living with major depressive disorder (MDD), often detecting the probability of a relapse weeks or months before the episode occurs. Approximately 60 per cent of people with MDD relapse within five years, even with treatment.

backblaze.com marks 13 years of collecting Hard Drive Stats data. Statistics such as these provide folks who may not be keeping such detailed records to have a statistical approximation as to how and when their own hard drives might develop faults.

As of the end of 2025, Backblaze was monitoring 341,664 drives used to store data. For our evaluation, we removed from consideration 4,013 boot drives and 459 hard drives, as they did not meet the criteria to be included. Removing these drives leaves us with 337,192 hard drives to analyze.

See Backblaze’s detailed report on their disk inventory in the post here.

Top of the CircuitPython Tiny Wiki home page with details about basic usage along with a photo of the Adafruit Fruit Jam device it runs on.

Tiny Wiki is a small webserver that runs on a microcontroller and hosts a minimal Wiki system backed by markdown files. It was originally created by Kevin McAleer for Micropython devices. You can create and edit pages, linking them together to form a Wiki structure. This guide features a CircuitPython port of the Tiny Wiki project. It is built using the CircuitPython HTTPServer and TemplateEngine libraries. It was designed for the Adafruit Fruit Jam, but could be adapted for other CircuitPython devices with access to WiFi and a microSD card.

Kris Slyka has a bit of an obsession with vintage analogue video cameras.

A few weeks ago I felt like it was finally time to take the next step and get myself one of those “televisions” I had heard so much about. Stop feeding those pristine analogue signals into a digital capture card and instead enjoy them fully analogue, end to end, crt to crt.

Turns out that one of the reasons this TV was so cheap was because it doesn’t have any video input besides an antenna. And it’s black and white. Both of which are deeply disappointing to gamers. And since analogue video broadcasts around here have stopped like a decade ago I couldn’t even enjoy our high quality domestic TV programming, let alone connect any of my weird cameras.

So, there’s two options here, basically: Either, mod the TV for composite video input (not too hard) or just get an RF modulator (easy).

After realizing that broadcast television uses negative modulation I was able to hack together a little inverter and amplifier circuit, hook up one of my cameras and get beautifully bad looking low latency video, no computers involved! Easy!

See how Kris performed this electronic magic in the post here.
