In the search for happiness, having a good day every day is surely crucial. But when there are so many pursuits competing for our attention, sometimes it's difficult to know how much time to allocate for each one. Now, scientists in Canada claim to cracked the code for the perfect day – and surprisingly, it includes a short shift at work. According to the experts, the formula for the perfect day is six hours of family time, two hours spent with friends, 1.5 hour socialising, two hours exercising and one hour eating and drinking. Additionally, the perfect day should involve no more than six hours of work and less than 15 minutes commuting.

Chatbots could take over eight million jobs in the UK - and women will be worst affected, a leading think tank has warned. Analysis has found nearly two-thirds of tasks carried out by workers could be automated by AI, with admin and entry-level jobs most at risk. But the Institute for Public Policy Research (IPPR) claims the'jobs apocalypse' is not inevitable if the Government acts fast to ensure humans are not replaced. With the right regulation and fiscal incentives, it has estimated AI could instead boost the UK economy by 306bn - and even increase salaries for some by over a third. The report is the first of its kind to look at the impact of generative AI - the technology that mimics the human brain in generating text, images, and videos from scratch - on the UK labour market.

Zapping the brain could help people who struggle with maths get better at arithmetic. Researchers gave 102 people a set of tricky arithmetic problems, which each involved multiplying a double-digit number by a single-digit number, like 16 x 3 48. Half of the people in the study had their brain zapped with a mild electric current to stimulate their brain cells. People given the brain stimulation, and also tested under more difficult learning conditions, answered the questions in about half the time, compared to people whose brains were not zapped, researchers claim. They reportedly got the answers 52 per cent quicker.

A model human embryo with a heartbeat and traces of blood has been created by scientists in a move that could offer insights into the first weeks of life. The synthetic structure was created from human stem cells without the need for eggs, sperm or fertilisation. It replicates some of the cells and structures that would usually appear in the third and fourth weeks of pregnancy, but was designed to never have the ability to develop into a foetus. Despite the heartbeat, the structure does not have the tissues that go on to form the placenta and yolk sac in a natural embryo. 'I'd like to emphasise that these are neither embryos nor are we trying to make embryos,' said Dr Jitesh Neupane, from the University of Cambridge's Gurdon Institute.

Artificial intelligence software is poised to drastically slash NHS cardiology waiting lists and give heart patients a faster diagnosis. The program can carry out complicated measurements in less than a minute that normally take doctors about 20 minutes. Patients with heart problems usually undergo MRI scans to determine how enlarged the chambers of the organ are – a sign that it is under strain – and whether they will need invasive surgery or can be treated with medication. The scan captures about ten different images of the heart, each from a slightly different angle, to create a full picture. Doctors then have to print out these scans and painstakingly measure the size of the chambers by physically drawing on them.

FILE photo - Texas sued Meta on Monday over misuse of biometric data, the latest round of litigation between governments and the company over privacy. FILE photo - Texas sued Meta on Monday over misuse of biometric data, the latest round of litigation between governments and the company over privacy. Texas sued Facebook parent company Meta for exploiting the biometric data of millions of people in the state - including those who used the platform and those who did not. The company, according to a suit filed by state Attorney General Ken Paxton, violated state privacy laws and should be responsible for billions of dollars in damages. The suit involves Facebook's "tag suggestions" feature, which the company ended last year, that used facial recognition to encourage users to link the photo to a friend's profile.

Trying to identify a wild bird while frantically leafing through a bird-spotters' guide is no easy task. But modern technology has come to the rescue, with artificial intelligence trained to help out amateur twitchers. Where people may be confused by two similar looking birds, or a juvenile which does not yet have its adult plumage, AI has been found to identify birds with up to around 90 per cent accuracy. The technology was trained using pictures of wild great tits and sociable weavers, as well as captive zebra finches. It works in a similar way to the face-recognition programmes used to identify people in crowds.

Seaborne robots have made a startling discovery beneath a 20-mile glacier in Alaska. The technology found the massive rivers of ice may be melting under the LeConte Glacier much faster than previously thought. Scientists programmed autonomous kayaks to swim near the icy cliffs of the glacier to measure the'ambient meltwater intrusions', which shows how much fresh water is flowing into the ocean from underneath the glacier. The study found ambient melting was 100 times higher than models had estimated. This is the first time experts have been able to analyze plumes of meltwater - the water released when snow or ice melts, where glaciers meet the ocean- because the feat is far too dangerous for ships due to falling ice of slabs from the glacier.

A new iOS update may be quietly patching up a software flaw that sent some of Apple's smart speakers spiraling out of commission. As reported by MacRumors, Apple has introduced yet another update to its iOS - the third update since it was release in September. Notably, however, the only change appears to be relating to software for the its Homepod, the company's only smart speaker. Apple hasn't said outright that this new software will correct the issue, but as noted by The Verge, it's unlikely the company would roll out any updates without correcting flaws in previous software. Apple's Homepod encountered an update issue that rendered the device unusable.

Researchers successfully sneaked malicious apps behind the defenses of two major smart speaker companies in a test on their security practices. Experts at Security Research Labs say the apps were design to target personal data like voice-recordings and passwords of both Google Home and Amazon Echo users by posing as software that reads horoscopes through voice-commands. The apps were only removed once researchers made the company aware of their test. All eight of the apps designed by the researchers were able to bypass Amazon and Google defenses and were approved by the companies' moderation teams - a lapse that experts say invites even greater scrutiny on smart devices' privacy and safety standards. 'As the functionality of smart speakers grows so too does the attack surface for hackers to exploit them,' write the researchers in their report.
