Everyone has heard of Kaggle, but have you heard of London-based Google DeepMind? Their researchers build deep learning algorithms to conquer everything from Pong and the ancient game of go to blindness caused by diabetic retinopathy. If the latter sounds particularly familiar, you may be recalling the Diabetic Retinopathy Detection competition which ran on Kaggle from February 2015 to July 2015. In this blog post, I interview Jeffrey De Fauw who came in 5th place in this competition using convolutional neural networks and is first author of Google DeepMind's study spearheading efforts to automate analysis of ophthalmic images using machine learning in order to help clinicians diagnose sight-threatening diseases. He explains how he got started on Kaggle, how it led him to his current role at DeepMind, and what he's learned along the way.

The classifiers can be represented as discrimination maps, where a red color indicates that the intensity at that location contributes to the likelihood of the images belonging to the more advanced stage, and a blue color to the likelihood of belonging to the less advanced stage. Weights are shown inside the mask that resulted in the highest accuracies for each classification: A: Alzheimer's disease (AD) vs. subjective cognitive decline (SCD); B: AD vs. mild cognitive impairment (MCI); C: MCI vs. SCD. At the VU University Medical Center Amsterdam researchers are harnessing the power of artificial intelligence to be able to detect early signs of Alzheimer's on MRI scans. The parenchyma exhibits small incremental changes on the scan as the disease develops, but these are difficult to spot in new patients. Only once the disease is at a later stage clinicians are able to identify the disease from the scans, but by then it's usually already exhibiting well known symptoms.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

This week, a relatively young cybersecurity company called Darktrace announced that it has raised an additional 65 million ( 50 million) at a suspected valuation of over 400 million ( 308 million). No other UK tech startup has announced a funding round anywhere near that size since the UK voted for Brexit. We caught up with Mike Lynch -- the billionaire founder of enterprise software firm Autonomy and Darktrace's first big name investor -- to find out why he decided to put his money into the company. "The reason I liked it was that it was a completely new approach," said Lynch during a phone call with Business Insider on Wednesday. "Most of what's out there in cybersecurity is based on knowing what you're looking. So things like anti-virus and that sort of stuff or trying to build a big wall around the outside of your company, a boundary. "The problem is that the world's moved on and the attacks no longer have signatures.

DEEPMIND, Google's London-based artificial intelligence company, has started training neural networks to recognise the signs of eye disease in medical images. A partnership with Moorfields Eye Hospital in London has given the company access to about a million anonymised retinal scans, which DeepMind will feed into its artificial intelligence software. The project will target two of the most common eye diseases – age-related macular degeneration and diabetic retinopathy. More than 100 million people around the world have these conditions. Moorfields is providing scans of the back of people's eyes, as well as more detailed scans known as optical coherence tomography (OCT). The idea is that the images will let DeepMind's neural networks learn to recognise subtle signs of degenerating eye conditions that even trained clinicians have trouble spotting.

"Flint seeks to invest in ground-breaking technologies that directly improve human life," said Flint Capital Partner Artem Burachenok. "Findo's ability to mitigate the growing challenge of massive data in everyone's inbox, cloud and storage solution is a game changer." Findo's smart search engine helps users quickly find information buried in a wide array of documents, slides, audio files, images, or any other information from sources as varied as Dropbox, Google Drive, Evernote and Gmail, Exchange and Outlook. Findo search bots can search from Slack, Telegram, Facebook Messenger and Skype and deliver results right to the messenger. "We are excited to have Flint as one of our investors," said Gary A. Fowler, Co-Founder and CEO of Findo.

WASHINGTON – Congress passed an aviation bill Wednesday that attempts to close gaps in airport security and shorten screening lines, but leaves thornier issues unresolved. The bill also extends the Federal Aviation Administration's programs for 14 months at current funding levels. It was approved in the Senate by a vote of 89 to 4. The House had passed the measure earlier in the week and it now goes to President Barack Obama, who must sign the bill by Friday when the FAA's current operating authority expires to avoid a partial agency shutdown. Responding to attacks by violent extremists associated with the Islamic State group on airports in Brussels and Istanbul, the bill includes an array of provisions aimed at protecting "soft targets" outside security perimeters. Other provisions designed to address potential "insider threats" would toughen vetting of airport workers and other employees with access to secure areas, expand random employee inspections and require reviews of perimeter security.

Newspapers and politicians around the world have been reacting to Boris Johnson's appointment as UK foreign secretary. Many were surprised, citing his history of faux pas including insulting the president of Turkey and commenting on the US president's ancestry. Here we take a look at the response in countries where Mr Johnson will now represent the UK. The Washington Post publishes a round-up of "undiplomatic" things Mr Johnson has said during his time in public life. Washington Post writer Ishaan Tharoor also writes that Mr Johnson "has controversially bucked the Western trend and praised Syrian President Bashar al-Assad for battling the Islamic State, no matter its parallel campaign of violence on Syria's civilian population".

An anonymous reader quotes a report from Reuters: A former Google engineer, whose speech recognition software is used in more than a billion Android smartphones, has launched a company that uses blockchain technology to build a new operating system for banks. Paul Taylor, a Cambridge University academic with an expertise in artificial intelligence, speech synthesis and machine learning, started working on the system, called Vault OS, two years ago in a basement in London's Shoreditch district, known for being a tech start-up hub. The technology, which underpins the digital currency bitcoin, creates a shared database in which participants can trace every transaction ever made. The ledger is tamper-proof and transparent, meaning that transactions can be processed without the need for third-party verification. The system also negates the need for costly in-house data centers, as it uses cloud-based systems, which banks can use on a "pay-as-you-go" basis, which means that there is no single point of failure.
