AI Automatically Sorts Cancer Cells to determine most effective treatment

A team of researchers in Japan have devised an artificial intelligence (AI) system that can identify different types of cancer cells using microscopy images. Their method can also be used to determine whether the cancer cells are sensitive to radiotherapy. The researchers reported their findings in the journal Cancer Research. In cancer patients, there can be tremendous variation in the types of cancer cells in a single tumor. Identifying the specific cell types present in tumors can be very useful when choosing the most effective treatment. However, making accurate assessments of cell types is time consuming and often hampered by human error and the limits of human sight. To overcome these challenges, scientists led by Professor Hideshi Ishii of Osaka University, Japan, have developed an AI system that can identify different types of cancer cells from microscopy images, achieving higher accuracy than human judgement. The system is based on a convolutional neural network, a form of AI modeled on the human visual system. “We first trained our system on 8,000 images of cells obtained from a phase-contrast microscope,” said corresponding author Ishii. “We then tested [the AI system’s] accuracy on another 2,000 images and showed that it had learned the features that distinguish mouse cancer cells from human ones, and radioresistant cancer cells from radiosensitive ones.” The researchers noted that the automation and high accuracy of their system could be very useful for determining exactly which cells are present in a tumor or circulating in the body. Knowing whether or not radioresistant cells are present is vital when deciding whether radiotherapy would be effective. Furthermore, the same procedure can be applied post-treatment to assess patient outcomes. In the future, the team hopes to train the system on more cancer cell types, with the eventual goal of establishing a universal system that can automatically identify and distinguish all variants of cancer cells.

This Roomba can create its own Doom levels

Game developer and designer Rich Whitehouse gave the world an unusual present this Christmas Eve. It’s called Doomba, and it uses the popular Roomba vacuuming robots to create levels for Doom, the classic first-person shooter.

Whitehouse is a 20-year veteran of the game industry, with credits on titles such as the original Prey and Star Wars Jedi Knight 2: Jedi Outcast. Along the way, he also built a tool called Neosis, which helps game developers and designers move digital assets between different platforms. The Doomba module works on similar principles; it just takes the digital maps created by the Roomba’s own internal software and converts them into Doom levels.

So what’s your Roomba doing creating maps of the inside of your house? Many of iRobot’s modern robotic vacuums rely on VSLAM, also known as visual simultaneous localization and mapping. Rather than wandering around like slow-moving ping-pong balls, modern Roomba devices methodically sweep back and forth in long passes like they’re mowing your lawn. That makes them much more efficient than previous models.

To do the work, some Roombas use a creepy little electronic eyeball to create detailed maps of your home. Doomba takes that map and makes it into a level of Hell.

As Whitehouse explains, it was fairly short work to turn his creation toward evil.

“I soon realized that there was a clear opportunity to serve the Dark Lord by conceiving a plethora of unholy algorithms in service to one of the finest works ever created in his name,” Whitehouse writes on his personal blog. “Simultaneously, I would be able to unleash a truly terrible pun to plague humankind. Now, the fruit of my labor is born. I bring forth DOOMBA, a half-goat, half-script creature, with native binary backing for the expensive parts, to be offered in place of my firstborn on this fine Christmas Eve.”

In Blow to Amazon and Walmart, India Bans a Key Part of Their Business Strategy

The Indian government sent a strong screw you to Amazon and the Walmart-owned Flipkart on Wednesday, banning e-commerce companies from selling products from companies that they have an equity interest in or “entering into exclusive agreements with sellers,” CNBC reported.

India already bans e-commerce sites from selling products directly, per the New York Times, which has led to them acquiring stakes in affiliate companies that serve much the same purpose at arm’s length. At issue is the power of e-commerce companies to make bulk purchases of goods that they then sell to “select sellers, such as their affiliates or other companies with which they have agreements,” CNBC wrote. The strategy allows giants like Amazon to offer products at low prices that smaller competitors often find hard to match.

In a statement to CNBC, India’s commerce ministry said the new rules would go into effect on Feb. 1, 2019, adding the new rules specify that: “An entity having equity participation by e-commerce marketplace entity or its group companies, or having control on its inventory by e-commerce marketplace entity or its group companies, will not be permitted to sell its products on the platform run by such marketplace entity.”

The move could mean Amazon would be forced “to stop competing with independent sellers and end its offerings of proprietary products like its Echo smart speakers in India, its top emerging market,” the Times wrote. It’s also a blow to Walmart, which bought a 77 percent stake in Flipkart for $16 billion this year, and may be forced to stop selling products produced by companies it owns. As the paper noted, both companies’ competitive strategies rely on highly efficient supply chains and pressuring retailers to comply with their requirements, so this is not a good sign for their Indian ambitions.

The Times wrote that the decision appears to have been motivated by concerns from India’s prime minister, right-wing populist culture warrior Narendra Modi, that his party is losing ground ahead of upcoming elections:

Prime Minister Narendra Modi of India initially courted foreign companies to invest more in the country after his 2014 election victory, but his administration has turned protectionist as his party’s re-election prospects have dimmed in recent months. Mr. Modi has increasingly sought to bolster Indian firms and curb foreign ones through new policies, including one that requires foreign companies like Visa, Mastercard and American Express to store all data about Indians on computers inside the country. The government has also declared its intention to impose tough new rules on the technology industry.

According to CNBC, beneficiaries of the move will likely include owners of small businesses like farms and corner stores, the latter of which “dominate Indian retailing,” who believe that U.S.-based tech giants are trying to undermine their economic position. The site added that the Confederation of All India Traders issued a statement saying that tech giants will no longer to be able to commit “malpractices, predatory pricing policies and deep discounting.”

However, the law was vaguely written and contains some sections that appear to contradict each other, lawyer Salman Waris of New Delhi’s TechLegis told the Times, which means that its ultimate impact remains unclear. The paper also noted that Amazon is well-known for navigating Indian law to remain in compliance without losing its ability to steer markets, though Walmart’s decision to acquire Flipkart has already been questioned by analysts as a potentially unwise financial move.
