Machine learning model helps scientists understand deadly cone snail toxins

Marine cone snails are host to a family of dangerous neurotoxins. Very little is known about how those toxins interact with the human body, making this an area of interest for medical drug research and an area of concern in national security spaces. For the first time, a team at Los Alamos National Laboratory has successfully trained a machine learning model that predicts how alpha conotoxins bind to specific human receptor subtypes, which could help researchers develop lifesaving anti-toxins.

“Because of the diversity and complexity of natural conotoxins, it is estimated that only 2% of them have been sequenced,” said Gnana Gnanakaran, theoretical biologist at Los Alamos. “No antidotes exist for conotoxins, but by using machine learning to predict conotoxin binding, we now have the ability to develop tools to understand and respond to these threats.”

The deadly secretions issued by any one of the more than 800 cone snail species represent a conglomeration of more than 1 million natural conotoxins. The research team concentrated their machine learning work on alpha conotoxins, a particularly prevalent and deadly conotoxin family.

Magnetizing the Future of Quantum Communication: Single-Photon Emission from Defective Tungsten Diselenide

Quantum communication is one of the most exciting frontiers in secure data transmission. Now, a groundbreaking discovery by researchers at Kyoto University offers a major leap forward: a single-photon source created using defective tungsten diselenide (WSe2), enhanced under the influence of a magnetic field. The result? A powerful and controllable emitter that could revolutionize quantum information technologies.

New ChatGPT AI agent proves that it is «not a robot» — CloudFlare trusted it without CAPTCHA

It turns out that one of the most common ways to check security on the Internet is just child’s play for ChatGPT Agent. The irony is that the test requires you to prove that you «not a bot», which the OpenAI bot managed to do…

Magnetizing quantum communication: Single-photon source created using defective tungsten diselenide

As the demand for more secure data transmission increases, conventional communication technologies are facing limitations imposed by classical physics, and are therefore approaching their limits in terms of security. Fortunately, quantum communication may help us overcome these restrictions.

Flaw in Gemini CLI AI coding assistant allowed stealthy code execution

A vulnerability in Google’s Gemini CLI allowed attackers to silently execute malicious commands and exfiltrate data from developers’ computers using allowlisted programs.

The flaw was discovered and reported to Google by the security firm Tracebit on June 27, with the tech giant releasing a fix in version 0.1.14, which became available on July 25.

Gemini CLI, first released on June 25, 2025, is a command-line interface tool developed by Google that enables developers to interact directly with Google’s Gemini AI from the terminal.
