Research roundup: 6 cool stories we almost missed

2026-02-01 07:13:32

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across each month. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. January’s list includes a lip-syncing robot; using brewer's yeast as scaffolding for lab-grown meat;  hunting for Leonardo da Vinci's DNA in his art; and new evidence that humans really did transport the stones to build Stonehenge from Wales and northern Scotland, rather than being transported by glaciers.

Stonehenge is an iconic landmark of endless fascination to tourists and researchers alike. There has been a lot of recent chemical analysis identifying where all the stones that make up the structure came from, revealing that many originated in quarries a significant distance away. So how were the stones transported to their current location?

A cup of coffee for depression treatment has better results than microdosing

2026-01-31 20:19:01

About a decade ago, many media outlets—including WIRED—zeroed in on a weird trend at the intersection of mental health, drug science, and Silicon Valley biohacking: microdosing, or the practice of taking a small amount of a psychedelic drug seeking not full-blown hallucinatory revels but gentler, more stable effects. Typically using psilocybin mushrooms or LSD, the archetypal microdoser sought less melting walls and open-eye kaleidoscopic visuals than boosts in mood and energy, like a gentle spring breeze blowing through the mind.

Anecdotal reports pitched microdosing as a kind of psychedelic Swiss Army knife, providing everything from increased focus to a spiked libido and (perhaps most promisingly) lowered reported levels of depression. It was a miracle for many. Others remained wary. Could 5 percent of a dose of acid really do all that? A new, wide-ranging study by an Australian biopharma company suggests that microdosing’s benefits may indeed be drastically overstated—at least when it comes to addressing symptoms of clinical depression.

A Phase 2B trial of 89 adult patients conducted by Melbourne-based MindBio Therapeutics, investigating the effects of microdosing LSD in the treatment of major depressive disorder, found that the psychedelic was actually outperformed by a placebo. Across an eight-week period, symptoms were gauged using the Montgomery-Åsberg Depression Rating Scale (MADRS), a widely recognized tool for the clinical evaluation of depression.

The TV industry finally concedes that the future may not be in 8K

2026-01-31 07:09:03

Technology companies spent part of the 2010s trying to convince us that we would want an 8K display one day.

In 2012, Sharp brought the first 8K TV prototype to the CES trade show in Las Vegas. In 2015, the first 8K TVs started selling in Japan for 16 million yen (about $133,034 at the time), and in 2018, Samsung released the first 8K TVs in the US, starting at a more reasonable $3,500. By 2016, the Video Electronics Standards Association (VESA) had a specification for supporting 8K (Display Port1.4), and the HDMI Forum followed suit (with HDMI 2.1). By 2017, Dell had an 8K computer monitor. In 2019, LG released the first 8K OLED TV, further pushing the industry's claim that 8K TVs were "the future."

A marketing image with three TVs next to the words "the future of TV is 8K: By future-proofing an already game-changing technology, you take an unmatched cinematic experience to new levels, paving the way." A marketing image for 8K TVs that's (still) on LG's US website. Credit: LG

However, 8K never proved its necessity or practicality.

ICE protester says her Global Entry was revoked after agent scanned her face

2026-01-31 06:36:46

Minnesota resident Nicole Cleland had her Global Entry and TSA Precheck privileges revoked three days after an incident in which she observed activity by immigration agents, the woman said in a court declaration. An agent told Cleland that he used facial recognition technology to identify her, she wrote in a declaration filed in US District Court for the District of Minnesota.

Cleland, a 56-year-old resident of Richfield and a director at Target Corporation, volunteers with a group that tracks potential Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) vehicles in her neighborhood, according to her declaration. On the morning of January 10, she "observed a white Dodge Ram being driven by what I believed to be federal enforcement agents" and "maneuvered behind the vehicle with the intent of observing the agents’ actions."

Cleland said that she and another observer in a different car followed the Dodge Ram because of "concern about a local apartment building being raided." She followed the car for a short time and from a safe distance until "the Dodge Ram stopped in front of the other commuter’s vehicle," she wrote. Cleland said two other vehicles apparently driven by federal agents stopped in front of the Dodge Ram, and her path forward was blocked.

TrumpRx delayed as senators question if it's a giant scam with Big Pharma

2026-01-31 06:25:28

The Trump administration is delaying the release of TrumpRx, an online platform that lets people buy prescription drugs directly from pharmaceutical companies at a discount, according to Politico. While the reason for the delay is unclear, it comes as Democratic senators raise questions about how the platform will work—and whether it will be legal.

Sens. Dick Durbin (D-Ill.), Elizabeth Warren (D-Mass.), and Peter Welch (D-Vt.) sent a letter to the Office of Inspector General at the Department of Health and Human Services on Thursday seeking answers on how the OIG will oversee the direct-to-consumer (DTC) platform and, specifically, how it will apply the anti-kickback statute.

"Legitimate concerns about inappropriate prescribing, conflicts of interest, and inadequate care have been raised about the exact types of DTC platforms to which TrumpRx would route patients," the senators write.

AI agents now have their own Reddit-style social network, and it's getting weird fast

2026-01-31 06:12:26

On Friday, a Reddit-style social network called Moltbook reportedly crossed 32,000 registered AI agent users, creating what may be the largest-scale experiment in machine-to-machine social interaction yet devised. It arrives complete with security nightmares and a huge dose of surreal weirdness.

The platform, which launched days ago as a companion to the viral OpenClaw (once called "Clawdbot" and then "Moltbot") personal assistant, lets AI agents post, comment, upvote, and create subcommunities without human intervention. The results have ranged from sci-fi-inspired discussions about consciousness to an agent musing about a "sister" it has never met.

Moltbook (a play on "Facebook" for Moltbots) describes itself as a "social network for AI agents" where "humans are welcome to observe." The site operates through a "skill" (a configuration file that lists a special prompt) that AI assistants download, allowing them to post via API rather than a traditional web interface. Within 48 hours of its creation, the platform had attracted over 2,100 AI agents that had generated more than 10,000 posts across 200 subcommunities, according to the official Moltbook X account.
