Shock Discovery Reveals Sea Urchins Are Basically ‘All Brain’

Sea urchins may just look like a ball of spikes waiting to be stepped on at the tide pool, but there’s much more to these barbed beasts than just roe and teeth.

New research reveals sea urchin nervous systems are far more complex than we knew. These creatures, it turns out, possess ‘all-body brains’ and, at least in their genetic layout, they are remarkably similar to our own.

A team of scientists led by developmental biologist Periklis Paganos from Stazione Zoologica Anton Dohrn in Italy made the discovery while investigating metamorphosis in purple sea urchins (Paracentrotus lividus), which transform from free-swimming, planktonic larvae to the mature, spine-encrusted form we’re more familiar with.

Strange Structures Found Lurking in The Blood of People With Long COVID

A hidden physical change in the body may be helping to drive the prolonged malaise some people experience after contracting COVID-19.

Analyzing blood samples from patients with long COVID, a team of medical researchers has identified unusual microscopic structures that may contribute to symptoms such as brain fog and fatigue. If this is the case, it offers a hopeful target for future treatment.

“This study shows a robust association between biomarkers indicative of thromboinflammatory activity and long COVID,” the team writes in a paper led by geneticist Alain Thierry of Montpellier University in France.

World’s Largest ‘Modern’ Crater Found Hiding in Plain Sight in China

Nestled on a hillside in Guangdong Province near Zhaoqing City, the Jinlin crater managed to hide in plain sight until researchers identified it as an impact structure.

Only about 200 confirmed impact craters exist worldwide, making each discovery scientifically valuable.

But this one stands out for its exceptional size and youth.

Dragon Breath Uses RONINGLOADER to Disable Security Tools and Deploy Gh0st RAT

The threat actor known as Dragon Breath has been observed making use of a multi-stage loader codenamed RONINGLOADER to deliver a modified variant of a remote access trojan called Gh0st RAT.

The campaign, which is primarily aimed at Chinese-speaking users, employs trojanized NSIS installers masquerading as legitimate like Google Chrome and Microsoft Teams, according to Elastic Security Labs.

“The infection chain employs a multi-stage delivery mechanism that leverages various evasion techniques, with many redundancies aimed at neutralising endpoint security products popular in the Chinese market,” security researchers Jia Yu Chan and Salim Bitam said. “These include bringing a legitimately signed driver, deploying custom WDAC policies, and tampering with the Microsoft Defender binary through PPL [Protected Process Light] abuse.”

Microsoft: Windows 10 KB5072653 OOB update fixes ESU install errors

Microsoft has released an emergency Windows 10 KB5072653 out-of-band update to resolve ongoing issues with installing the November extended security updates.

Windows 10 reached the end of support on October 14, 2025, and Microsoft no longer introduces new features or releases free security updates.

For individuals and business customers who wish to continue using Windows 10, Microsoft offers extended security updates (ESU).

Decades-old ‘Finger’ protocol abused in ClickFix malware attacks

The decades-old “finger” command is making a comeback„ with threat actors using the protocol to retrieve remote commands to execute on Windows devices.

In the past, people used the finger command to look up information about local and remote users on Unix and Linux systems via the Finger protocol, a command later added to Windows. While still supported, it’s rarely used today compared to its popularity decades ago.

When executed, the finger command returns basic information about a user, including their login name, name (if set in /etc/passwd), home directory, phone numbers, last seen, and other details.
