University of Edinburgh tested 1000 people aged 70 for memory, problem solving, thinking speed and general thinking ability — the same people were tested every three years until they reached 79.
LONDON (AP) — Four African countries have reported new cases of polio linked to the oral vaccine, as global health numbers show there are now more children being paralyzed by viruses originating in vaccines than in the wild.
In a report late last week, the World Health Organization and partners noted nine new polio cases caused by the vaccine in Nigeria, Congo, Central African Republic and Angola. Seven countries elsewhere in Africa have similar outbreaks and cases have been reported in Asia, including the two countries where polio remains endemic, Afghanistan and Pakistan.
In rare cases, the live virus in oral polio vaccine can mutate into a form capable of sparking new outbreaks. All the current vaccine-derived polio cases have been sparked by a Type 2 virus contained in the vaccine. Type 2 wild virus was eliminated years ago.
New research in mice finds that blocking a key molecule can slow the progression of multiple sclerosis. The findings pave the way for new treatments.
Tim Berners-Lee, the inventor of the world wide web, has officially launched the Contract for the Web, a set of principles designed to “fix” the internet and prevent us from sliding into a “digital dystopia,” The Guardian reports. The contract lists nine core principles for governments, companies, and individuals to adhere to, including responsibilities to provide affordable, reliable internet access and to respect civil discourse and human dignity.
At launch, the initiative has received the backing of over 150 organizations, including tech companies such as Microsoft, Google, DuckDuckGo, and Facebook, and nonprofit groups such as the Electronic Frontier Foundation. The Guardian initially reported that Amazon and Twitter were absent from the list of backers, however as of November 25th, Twitter’s logo has appeared on the Contract’s homepage. Twitter’s increasing role in political discourse was recently brought into sharp focus after it chose to ban political ads on its platform, citing the “challenges to civic discourse” that they create.
The contract’s launch comes as tech companies such as Facebook and Google have faced mounting pressure around both the amount of user data they collect, and the ways in which they collect it. The Contract for the Web includes principles designed to prevent this, including a requirement for companies to respect people’s privacy and personal data. If companies do not show that they are working to support these aims they risk being removed from the list of the project’s endorsers.
Park Las Vegas, sponsored by Bleutech Park Properties, Inc. is breaking ground in the Las Vegas Valley in December 2019 as the first city in the world to boast a digital revolution in motion, redefining the infrastructure industry sector. This $7.5 billion, six year project, will be constructed of net-zero buildings within their own insular mini-city, featuring automated multi-functional designs, renewable energies from solar/wind/water/kinetic, autonomous vehicles, artificial intelligence (AI), augmented reality, Internet of Things (IoT), robotics, supertrees, and self-healing concrete structures.
Bleutech Park’s mixed-use environment featuring workforce housing, offices, retail space, ultra-luxury residential, hotel and entertainment will introduce a new high-tech biome to the desert valley.
Two security sleuths last month discovered an enormous amount of data that was left exposed on a server. Data found on the server belonged to around 1.2 billion people.
Kartikay Mehrotra wrote about it on Friday for Bloomberg, in a story, along with one from Wired, that was frequently quoted over the weekend. The data was left unprotected on a Google Cloud server.
The FBI were contacted and the server was shut down. Not trivial. Wired referred to the situation as a “jumbo” data leak. Wired said the information was sitting exposed and easily accessible on an unsecured server.
An international team led by researchers at Princeton University has directly observed a surprising quantum effect in a high-temperature iron-containing superconductor.
Superconductors conduct electricity without resistance, making them valuable for long-distance electricity transmission and many other energy-saving applications. Conventional superconductors operate only at extremely low temperatures, but certain iron-based materials discovered roughly a decade ago can superconduct at relatively high temperatures and have drawn the attention of researchers.
Exactly how superconductivity forms in iron-based materials is something of a mystery, especially since iron’s magnetism would seem to conflict with the emergence of superconductivity. A deeper understanding of unconventional materials such as iron-based superconductors could lead eventually to new applications for next-generation energy-saving technologies.
As genetic sequencing becomes more widespread, a disconnect is emerging between what individual patients expect to get back and what scientists are willing and able to tell them. WSJ visited MIT’s Broad Institute to learn about the murky world of genomic research data.

Sugar poses one of the most pressing health problems in the modern world – not least because it’s just so delicious. Rather than quitting sweets cold turkey, low-calorie alternatives to sucrose could make tasty treats that are at least less bad for us. And now, researchers from Tufts University have developed a more efficient method for producing one such sweetener, using farms of bacteria.
The sugar in question is called tagatose, which the FDA says is “generally regarded as safe.” It’s 92 percent as sweet as sucrose – regular old table sugar – but because the human digestive system doesn’t metabolize as much of it, it only has 38 percent of the calories. That, in turn, means tagatose has a much smaller effect on blood glucose and insulin, making it safe for diabetics. And to cap it off, tests show that it doesn’t contribute to cavities or tooth decay.
But, of course, there’s a catch – tagatose is a little complicated to produce. Normally, it’s done by hydrolyzing lactose to make galactose, which is then isomerized into tagatose, which then needs to be purified and crystallized into a solid, usable form. Yields from this process are low, at less than 30 percent.
