Scientists create remote-controlled flies by hacking their brains – Yahoo Finance UK

NFTs have become a powerful tool with their ability to exist beyond the control of centralised authorities
Scientists have figured out how to hack the brains of fruit flies in order to control them wirelessly.
A team of neuroengineers led by Rice University were able to use magnetic signals to activate targeted neurons that control the body position and movement of the flies.
The remote-controlled insects represent the “holy grail” of neurotechnologies, according to Rice University’s Jacob Robinson, as the science could be used in everything from treating diseases, to developing brain-machine interfaces.
To achieve the feat, the research team brought together experts in genetic engineering, nanotechnology and electrical engineering. They began by genetically engineering the flies to express a certain heat-sensitive ion channel in their neurons.
By injecting iron oxide nanoparticles into their brains to act as a heat trigger, the researchers were able to use a magnetic field to heat up the particles and activate the neuron.
The specific neuron they chose was one that caused the insects to spread their wings, which is a common mating gesture.
A demonstration of the technique, published in the scientific journal Nature Materials, showed that it was able to activate neural circuits 50 times faster than any previous technology.
“To study the brain or to treat neurological disorders, the scientific community is searching for tools that are both incredibly precise, but also minimally invasive,” said Robinson, an associate professor in electrical and computer engineering at Rice University and one of the study’s authors.
“Remote control of select neural circuits with magnetic fields is somewhat of a holy grail for neurotechnologies. Our work takes an important step towards that goal because it increases the speed of remote magnetic control, making it closer to the natural speed of the brain.”
Scientists have invented a solar-powered fuel production system that they claim could help the aviation industry become carbon neutral. The innovative tower design uses the Sun’s energy to facilitate the process of converting water (H20) and carbon dioxide (CO2) into liquid hydrocarbons like kerosene. “We are the first to demonstrate the entire thermochemical process chain from water and CO2 to kerosene in a fully-integrated solar tower system,” said Professor Aldo Steinfeld from ETH Zurich.
An Englishman based in York filmed his “pool desk deluxe” setup on July 19, amid a record-breaking heatwave in the UK.Jay Commins told Storyful that the concept started out “as a bit of fun,” before he realised that the idea was a genius way to beat the heat.In the video, originally published to TikTok, Commins can be seen stepping into a pool to sit at his desk. The “deluxe” set up also included a parasol, coffee maker, sunscreen, desk fan, and defibrillator.The footage came as a response to an earlier video which only featured the laptop and desk. Commins said, “People commented that there might be a risk of electrocution from the laptop, hence the tongue-in-cheek ‘defibrillator’ being added in the second video.”Temperatures in York reached 38 degrees Celsius (100 degrees Fahrenheit) on July 19.

A golden retriever amused his owners as he tried to climb into the back of a pickup truck in Wyoming.Amber Avery, who recorded this video on June 20, told Storyful she and her husband Kyle have been trying to teach their 1-year-old dog, Jeter, to hop into the back of the vehicle.The video shows the sweet pup attempting to climb on while Kyle coaxes him from the bed of the truck.“He prefers to be lifted,” Amber told Storyful. “He still will not jump. As you can see, he will only use that step!” Credit: Amber Avery via Storyful
Bluebell Capital Partners wants Swiss luxury goods group Richemont to concentrate on jewellery and watches, the activist fund manager told Reuters on Wednesday, saying such a move could double its share price in the medium term. "We would like them to focus on what they are good at, which is hard luxury — jewellery and watches," Bluebell partner Marco Taricco said in a telephone interview, a day after it emerged that the fund was seeking board changes at Richemont. Sharpening its focus would help Richemont narrow the discount in valuation to French group Hermes, Taricco said, suggesting Richemont rename itself the Cartier group to capitalise on its "fantastic, iconic brand".

Bitcoin rebounded after a brief sell-off late on Wednesday sparked by news that electric carmaker Tesla Inc had sold about 75% of its holdings of the virtual token. Tesla Chief Executive Elon Musk cited concerns about his company's "overall liquidity" as the reason for the sale.

PROFESSIONAL investors are sitting on the sidelines nervous about the economy and wobbling markets, but the amateurs are still piling in, figures from two top City firms today suggest. IG and AJ Bell both said customers numbers are rising as clients they gained during lockdown keep on punting. While big fund managers have seen outflows of cash due to fading performance and investor nerves, AJ Bell said assets in the last year are up a bit at £63.5 billion, “strong growth…in what is an uncertain economic environment”, it said.

There should be no need for a costly prospectus for most secondary fundraisings by companies, a government-backed review recommended on Tuesday as part of Britain's efforts to make its financial sector more globally attractive. The review by Freshfields Bruckhaus Deringer lawyer Mark Austin said that materially raising the threshold at which a prospectus should be required for an admission to trading on markets would speed up secondary fundraising. A prospectus is needed if a secondary raising is more than 20% of the existing share capital, but the review recommends raising this to 75% given that prospectuses are "inherently duplicative of a company's existing market disclosure", the review said.
