Scientists create diamonds at room temperature in minutes

Diamonds might be forever, but that doesn't mean they have to take eons to form. The gemstones are usually created after carbon is crushed and heated far beneath the Earth's surface over billions of years -- which is what makes them so coveted. Now, scientists in Australia say they have sped up the process into just a matter of minutes -- and at room temperature. An international team of researchers led by the Australian National University (ANU) and RMIT University in Melbourne, Australia said Wednesday they have created two types of diamond at room temperature by using high pressure equivalent…

With this scientific breakthrough, ageing is now optional

Scientists claim they have successfully reversed the human ageing process in a group of elderly adults in a breakthrough study. Oxygen treatment altered the elderly people's bodies at a cellular level to how they were 25 years earlier, researchers claimed. In a unique study, scientists used oxygen therapy to reverse two key indicators of biological ageing - telomere shortening and an accumulation of malfunctioning senescent cells. As humans age, their bodies experience the shortening of telomeres - the protective caps on chromosomes - which leads to illnesses including cancer, Alzheimer's and Parkinson's. Senescent cells, or so-called zombie cells, prevent regeneration…

Waste not, want not: Students build electric car from plastic, other waste materials

Dutch students have created a fully functioning electric car made entirely out of waste, including plastics fished out of the sea, recycled PET bottles and household garbage. The bright yellow, sporty two-seater which the students named ‘Luca’, can reach a top speed of 90 kilometres (56 miles) per hour and has a reach of 220 kilometres when fully charged, the Technical University of Eindhoven said. “This car is really special, because it’s made all out of waste”, project manager Lisa van Etten told Reuters. “Our chassis is made out of flax and recycled PET bottles. For the interior we also…

New Covid-19 vaccine promises 95 percent protection

A new vaccine that protects against Covid-19 is nearly 95% effective, early data from US company Moderna shows. The results come hot on the heels of similar results from Pfizer, and add to growing confidence that vaccines can help end the pandemic. Both companies used a highly innovative and experimental approach to designing their vaccines. Moderna says it is a "great day" and they plan to apply for approval to use the vaccine in the next few weeks. However, this is still early data and key questions remain unanswered. How good is it? The trial involved 30,000 people in the…

Pfizer vaccine trial success signals breakthrough in pandemic battle

Pfizer Inc's (PFE.N) exnperimental Covid-19 vaccine is more than 90% effective based on initial trial results, the drugmaker said on Monday, a major victory in the war against a virus that has killed over a million people and battered the world's economy. Scientists, public health officials and investors welcomed the first successful interim data from a large-scale clinical test as a watershed moment that could help turn the tide of the pandemic if the full trial results pan out. However, mass roll-outs, which needs regulatory approval, will not happen this year and several vaccines are seen as necessary to meet…

8 new uses for your old smartphone

Just because you got a nifty new phone doesn’t mean you have to ditch your old one The excitement of getting a new phone is often tempered by nagging regret. A lot of times, it’s not like there was anything really wrong with the old phone (unless there was — a bulging battery or a shattered screen is always a bad look). If it was a breakup, the conversation with an old phone would start, “You’re terrific. It’s not you. It’s me. I just wanted a newer model.” Ashamed of yourself? Don’t be. There’s no need to stick the old…

WhatsApp is introducing ‘disappearing messages’. This is how it’ll work

WhatsApp is introducing a "disappearing messages" option that will erase chats from the phone of both the sender and recipient after seven days. The Facebook-owned app, which has two billion users worldwide, said the setting would help keep chats private. But it said recipients would still be able to screenshot or forward any messages, photos or videos that they wanted to keep. The option will appear for WhatsApp users by the end of November. In a blog, the company said messages could be set to expire after seven days to offer "peace of mind that conversations aren't permanent, while remaining…

Scientists provide reasons why people in some countries are taller than those in others

Poor diets for school-age children may contribute to an average height gap of 20cm (7.9in) between the tallest and shortest nations, an analysis suggests. It reports that in 2019 the tallest 19-year-old boys lived in the Netherlands (183.8cm or 6ft) and the shortest lived in Timor Leste (160.1cm or 5ft 3in). Meanwhile the UK's global height ranking fell, with 19-year-old boys being 39th tallest in 2019 (1.78m or 5ft 10in) from 28th tallest in 1985. The study appears in The Lancet. Researchers say tracking changes in the height and weight of children across the world and over time is important…

The most popular painkiller on the planet has been poisoning people

5-storey building in Shanghai 'walks' to a new location

Shanghai residents passing through the city's eastern Huangpu district earlier this month might have stumbled upon an unusual sight: a "walking" building. An 85-year-old primary school has been lifted off the ground -- in its entirety -- and relocated using new technology dubbed the "walking machine." In the city's latest effort to preserve historic structures, engineers attached nearly 200 mobile supports under the five-story building, according to Lan Wuji, chief technical supervisor of the project. The supports act like robotic legs. They're split into two groups which alternately rise up and down, imitating the human stride. Attached sensors help control…

MTN, 9mobile get nod for national roaming

Nigerian Communications Commission (NCC) has granted two mobile network operators MTN and 9mobile approval to carry out trial on National roaming services. Roaming Service enables a mobile subscriber to automatically make and receive voice calls, send and receive data, or access other services when travelling outside the coverage of a particular network geographical area by utilising the network coverage of other networks. National roaming services means that subscribers in Nigeria can seamlessly make calls in areas of the country their Network operators do not cover because such networks have entered into agreement with other operators that have services in those…

Google hit by landmark competition lawsuit in US over search
