LastPass Breach

Wired: "Yes, It's Time to Ditch LastPass"

WIRED recommends 1Password and the free service Bitwarden, along with some alternatives. We haven't recommended LastPass since the company scaled back its free offerings a couple of years ago, given that LastPass had suffered an array of past security incidents before this latest, most dire breach was even revealed.

“One hundred percent, yes, people should switch to other password managers,” says one senior security engineer, who asked not to be named because of professional relationships with people on the LastPass security team. “They failed to do the one thing they are supposed to provide—cloud-based secure credential storage.”

"Wakanda Forever, Starring MIT":

If you’ve seen Black Panther: Wakanda Forever, you already know that MIT is featured in the film. Spoiler alert: Don’t continue reading if you haven’t seen the film, as details are covered below...

The movie, released November 11, features scenes from around campus and Cambridge, including outside the Stratton Student Center near the Kresge Oval, a dorm room in Simmons Hall, and a fight/chase scene on the Massachusetts Avenue bridge...

Why film at MIT? Not to give away too many details, but Stark isn’t the only superhero to attend the Institute. In this latest box office hit, 19-year-old MIT student Riri Williams finds herself and one of her inventions (a school project on steroids) at the center of an international crisis. In an effort to avert disaster, two people from Wakanda (a fictional East African country) travel to Cambridge to find her...

Nonstandard Ages In South Korea

"How Old Are You? South Korea Tries to Simplify What Should Be a Simple Question": 

South Koreans have counted their ages in three different ways for decades. In everyday life, they are a year old at birth and count up every New Year’s Day. In some contexts -- when determining one’s eligibility to drink, smoke or serve in the military, for example -- they simply subtract their birth year from the current year. And for most legal and official purposes, they follow the rest of the world: People start from 0 and add a year on every birthday. 

Once the bill is signed into law, the government would follow the international approach. Babies under a year old will have their age counted in months...

Mouse Neuron Data

"Huge new dataset pushes limits of neuroscience":

At the Allen Institute, a nonprofit research institute started by Microsoft cofounder Paul Allen, they used six Neuropixels probes to record simultaneously from eight different regions of the mouse visual system. In August, the institute released data from 81 mice—comprising the activity of around 300,000 neurons. The data is freely available to any researchers who might want to use it.

As the largest data set of this kind ever collected—three times as big as the previous record holder—the release lets researchers observe enormous groups of neurons acting in concert. That unprecedented scale may unlock opportunities to understand parts of cognition that have previously evaded the scientific community’s grasp. “We want to understand how we think and see and make decisions,” says Shawn Olsen, an investigator at the Allen Institute who played a central role in the project. “And it just does not happen at the level of single neurons.”

The challenge now is figuring out just how to parse all that data...

The machine’s movements are accomplished by using a custom technology that translates electrical signals from the plant into real-time motion. Embedded patch sensors pick up electric signals from the leaves and transmit them to the machine that contains several joints that determine how the machete swings, jabs, slices, and interacts in space.

Key excerpts of the first article:

[T]he revelation that thousands of agents have access to a searchable database without public oversight is a new development in what privacy advocates and some lawmakers warn could be an infringement of Americans’ Fourth Amendment rights against unreasonable searches and seizures.

In a 2018 filing, a CBP official said an officer could access any device, including in cases where they have no suspicion the traveler has done anything wrong, and look at anything that “would ordinarily be visible by scrolling through the phone manually,” including contact lists, calendar entries, messages, photos and videos.

If officers have a “reasonable suspicion” that the traveler is breaking the law or poses a “national security concern,” they can run an “advanced search,” connecting the phone to a device that copies its contents. That data is then stored in the Automated Targeting System database, which CBP officials can search at any time.

Here are some tips on how best to protect your data privacy at the border crossing.

"Plaintiff Jane Doe, a sexual assault survivor, was re-victimized by this unconstitutional practice," alleged the lawsuit filed Monday in US District Court for the Northern District of California. "In 2016, she provided a DNA sample to the San Francisco Police Department as part of its investigation into her sexual assault. However, she never consented to it to be stored or used for any other purpose. Nevertheless, the Department maintained Plaintiff Doe's DNA in the database for more than six years."

According to the lawsuit, Jane Doe was arrested on burglary charges in 2021 after DNA from a crime scene apparently matched the DNA she provided five years earlier. The charges were eventually dropped...

Not A Star

"French scientist Etienne Klein apologises after 'James Webb Telescope' image revealed as slice of chorizo". As friend SDW quipped, "Goes well with a moon made of cheese.":

Etienne Klein, a director at France's Atomic Energy Commission, posted a picture purportedly showing Proxima Centauri, the closest star to our sun...

However, Professor Klein has now admitted that the glowing celestial body shown was in fact nothing more than a slice of Spanish chorizo sausage.

TikTok Vigilantism?

NYT: "A Stranger Filmed Her on the Train. TikTok Users Decided She Had Monkeypox."

Summary: A woman with neurofibromatosis (a non-infectious disease than can cause skin lesions) is filmed by stranger while she is on NYC subway. The video is posted to TikTok with strong implication that she has monkey pox, and the woman receives many reactions including threats of physical violence.

This is one of the downsides of the widespread use of personal cameras. (There are many good aspects as well.)

The article correctly notes that the filming was legal, given that it was in a public setting with reduced "reasonable expectation of privacy."

Hazing And Solidarity

"Does hazing actually increase group solidarity? Re-examining a classic theory with a modern fraternity"

Using an American social fraternity, we report a longitudinal test of the relationship between hazing severity and group solidarity. We tracked six sets of fraternity inductees as they underwent the fraternity's months-long induction process. Our results provide little support for common models of solidarity and suggest that hazing may not be the social glue it has long been assumed to be.

Farritor and Rachael Wagner, an engineering graduate student, will write software, configure MIRA to fit inside a space station experiment locker and exhaustively test the device to make sure it’s robust enough to survive launch and its systems will perform as anticipated in space.

Contactless Fabrication Using Acousic Levitation

Video: "Contactless Fabrication using Full Acoustic Trapping of Elongated Parts"

LeviPrint is a system for assembling objects in a contactless manner using acoustic levitation. We explore a set of optimum acoustic fields that enables full trapping in position and orientation of elongated objects such as sticks. We then evaluate the capabilities of different ultrasonic levitators to dynamically manipulate these elongated objects. The combination of novel optimization algorithms and levitators enable the manipulation of sticks, beads and droplets to fabricate complex objects.

Here's the academic paper (warning -- lots of math).

The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which includes a new type of tetraquark. The findings, presented today at a CERN seminar, add three new exotic members to the growing list of new hadrons found at the LHC. They will help physicists better understand how quarks bind together into these composite particles.
