Scientists unlock key to reversible, non-hormonal male birth control

Posted by in categories: biotech/medical, genetics, sex

The team found that administering an HDAC inhibitor orally effectively halted sperm production and fertility in mice while preserving the sex drive.


Researchers are grappling with the challenge of developing effective male contraceptives as existing attempts to block sperm production, maturation, or fertilization have fallen short, either offering incomplete protection or leading to severe side effects.

Now, a team of researchers at the Salk Institute in the US has developed a novel approach to halting sperm production, which is both non-hormonal and reversible, marking a significant advancement in male contraception research.

New technology can reveal what’s hidden behind objects using algorithm

Posted by in categories: information science, law enforcement, mathematics, virtual reality

The technology can reconstruct a hidden scene in just minutes using advanced mathematical algorithms.


Potential use case scenarios

Law enforcement agencies could use the technology to gather critical information about a crime scene without disturbing the evidence. This could be especially useful in cases where the scene is dangerous or difficult to access. For example, the technology could be used to reconstruct the scene of a shooting or a hostage situation from a safe distance.

Let’s build the GPT Tokenizer

Posted by in categories: health, information science, robotics/AI

W/ Andrej Karpathy


The Tokenizer is a necessary and pervasive component of Large Language Models (LLMs), where it translates between strings and tokens (text chunks). Tokenizers are a completely separate stage of the LLM pipeline: they have their own training sets, training algorithms (Byte Pair Encoding), and after training implement two fundamental functions: encode() from strings to tokens, and decode() back from tokens to strings. In this lecture we build from scratch the Tokenizer used in the GPT series from OpenAI. In the process, we will see that a lot of weird behaviors and problems of LLMs actually trace back to tokenization. We’ll go through a number of these issues, discuss why tokenization is at fault, and why someone out there ideally finds a way to delete this stage entirely.

Inexpensive device that can harvest energy from a light breeze and store it as electricity

Posted by in categories: computing, mobile phones

Researchers from Nanyang Technological University in Singapore (NTU Singapore) have created a low-cost tool that can capture power from wind energy as moderate as a light breeze.

The gadget can create a voltage of three volts and energy power of up to 290 microwatts when exposed to winds with speeds as low as 2 meters per second (m/s). This is enough to power a commercial sensor device and allow it to transfer data to a smartphone or computer.
