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.

MIT researchers unveil a revolutionary smart glove integrating tactile feedback for enhanced learning, robotics, and virtual reality interactions.

Discover how MIT’s new smart glove is transforming education, robotics, and virtual reality experiences with personalized tactile feedback.

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.

The compound showed enhanced heat absorption due to quicker evaporation, superior cooling in suppressing TR propagation, and high water content with low conductivity.

Researchers propose ‘dry water’ as the breakthrough solution for extinguishing lithium-ion battery fires, easing global fire department concerns.

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.

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.

This study reveals a mechanism by which the environment, diet in this case, can influence cancer risk.

“With the world growing more crowded, the great powers strive to conquer other planets. The race is on. The interplanetary sea has been charted; the first caravelle of space is being constructed. Who will get there first? Who will be the new Columbus?” A robot probe is being readied to explore the secrets of the red planet, Mars. The only component lacking: a human brain. No body. Just the brain. It is needed to deal with unexpected crises in the cold, dark depths of space. The perfect volunteer is found in Colonel Barham, a brilliant but hot-tempered astronaut dying of leukemia. But all goes awry as, stripped of his mortal flesh, Barham — or rather his disembodied brain — is consumed with a newly-found power to control…or destroy. Project psychiatrist Major McKinnon (Grant Williams) diagnoses the brain as having delusions of grandeur…but, just perhaps, Col. Barham has achieved grandeur.

Largest polyatomic molecule created and stabilised at just above absolute zero provides new insights into quantum chemistry.
