Tech to aid video search, detection of disease and of fraud.

Artificial intelligence has been the secret sauce for some of the biggest technology companies. But technology giant Alphabet Inc.’s Google is betting big on ‘democratising’ artificial intelligence and machine learning and making them available to everyone — users, developers and enterprises.

From detecting and managing deadly diseases, reducing accident risks to discovering financial fraud, Google said that it aimed to improve the quality of life by lowering entry barriers to using these technologies. These technologies would also add a lot of value to self-driving cars, Google Photos’ search capabilities and even Snapchat filters that convert the images of users into animated pictures.

Researchers have successfully used spinach leaves to build functioning human heart tissue, complete with veins that can transport blood.

To tackle a chronic shortage of donor organs, scientists have been working on growing various tissues and even whole organs in the lab. But culturing a bunch of cells is only part of the solution — they simply won’t thrive without a constant blood supply.

It’s notoriously difficult to build a working network of fine blood vessels (also called vasculature), especially when you get down to capillaries, which are only 5 to 10 micrometres wide. Blood vessels transport the oxygen and nutrients that a lab-grown tissue sample needs to grow and function.

To put it mildly, sequencing and building a genome from scratch isn’t cheap. It’s sometimes affordable for human genomes, but it’s often prohibitively expensive (hundreds of thousands of dollars) whenever you’re charting new territory — say, a specific person or an unfamiliar species. A chromosome can have hundreds of millions of genetic base pairs, after all. Scientists may have a way to make it affordable across the board, however. They’ve developed a new method, 3D genome assembly, that can sequence and build genomes from the ground up for less than $10,000.

Where earlier approaches saw researchers using computers to stick small pieces of genetic code together, the new technique takes advantages of folding maps (which show how a 6.5ft long genome can cram into a cell’s nucleus) to quickly build out a sequence. As you only need short reads of DNA to make this happen, the cost is much lower. You also don’t need to know much about your sample organism going in.

As an example of what’s possible, the team completely assembled the three chromosomes for the Aedes aegypti mosquito for the first time. More complex organisms would require more work, of course, but the dramatically lower cost makes that more practical than ever. Provided the approach finds widespread use, it could be incredibly valuable for both biology and medicine.

A fire protection and security company recently launched a new product called the “Scott Sight,” a face mask that incorporates thermal imaging with a display screen.

Tyco’s Scott Safety is bringing a big upgrade to the field of firefighting with their newly released product, the Scott Sight. This hands-free device is the first in the industry that incorporates an in-mask thermal intelligence system, according to an April 18th press release from the fire protection and security company.

Facebook is developing at least four new consumer products that could be revealed at an April event, according to a new report.

The social network last year launched a futuristic hardware division called Building 8, which is said to be similar to Google X, the experimental lab behind the search company’s self-driving cars.

One of the prototypes created by Building 8 is a “brain computer interface” that sounds a lot like a platform once hinted at by Mark Zuckerberg, which would allow users to share information telepathically.

China has signaled that its future lies with reusable rockets to reduce cost and pollution; although they won’t be copying SpaceX’s landing techniques.

SpaceX were the early pioneers of reusable rocket technology, successfully landing first stage boosters after delivering cargo into orbit, but it looks as though China are keen to follow suit with their own rockets after recognizing benefits of reusability.
