During routine navigation in daily life, our brains use spatial mapping and memory to guide us from point A to point B. Just as routine: making a mistake in navigation that requires a course correction.

Now, researchers at Harvard Medical School have identified a specific group of neurons in a brain region involved in navigation that undergo bursts of activity when mice running a maze veer off course and correct their error.

The findings, published July 19 in Nature, bring scientists a step closer to understanding how navigation works, while raising new questions. These questions include the specific role these neurons play during navigation, and what they are doing in other brain regions where they are found.

Sometime during the Cretaceous Period, 125 million years ago, a feisty mammal the size of a domestic cat encountered a dinosaur three times its size and thought it looked like a tasty meal.

A fossil unearthed in northeastern China captures the two creatures — a badgerlike animal called Repenomamus robustus and a species of plant-eating dinosaur known as Psittacosaurus — forever locked in mortal combat.

It’s a dramatic instant in time that challenges the idea that the earliest mammals lived in the shadows of dinosaurs, said paleobiologist Jordan Mallon, a research scientist at the Canadian Museum of Nature.

For many people, when they hear China and genetic engineering in the same sentence, it is often synonymous with scandal, and gene-edited babies may spring to mind.

And, although it is true that nearly five years ago, researcher He Jiankui infamously claimed he had created the first ever gene-edited babies, before going to prison for three years, China has continued to pour a lot of money into genetic engineering research, and aims to become a global leader in the field.

“The accumulative amount of financing in the gene therapy field in China has exceeded $3.3 billion. Also, according to a Frost & Sullivan study, it is estimated that by 2025, gene therapy will reach a scale of nearly $17.89 billion in China,” said Fiona Gao, founding partner of Chinsiders.

Various reports say the claim is far from true.

Russian scientists are claiming that they have created the most powerful quantum computer in the history of their nation. They even presented the computer to Russian President Vladimir Putin, who visited the exhibition of quantum technology achievements by Rosatom, the State Nuclear Energy Corporation.

But as per a report, the claim is far from true and the computer won’t be breaking modern encryption codes anytime soon.

It is believed that Apple is creating its large language model in competition with OpenAI’s GPT-3 and GPT-4, Google’s Bert and LaMDA, Meta’s LLaMa-1 and LLaMa-2, among others.

Whenever Apple launches a new product, its competitors, developers, and starry-eyed consumers take it very seriously. And with the veritable craze over artificial intelligence (AI) tools, it was only a matter of time before the iPhone creator came up with something explosive.

It is believed that Apple is creating its large language model (LLM) in competition with OpenAI’s GPT-3 and GPT-4, Google’s Bert and LaMDA, Meta’s LLaMa-1 and LLaMa-2, among others. It is also being learned that Apple has created a chatbot service… More.

The estimate of 400 rogue planets comes from a nine-year-long survey called Microlensing Observations in Astrophysics (MOA).

The Nancy Roman Grace Telescope, an upcoming space observatory, might aid in the discovery of hundreds of rogue exoplanets.

Planets of this sort float freely through galaxies and are not gravitationally tied to any star system.
