Engineers develop miniaturized ‘warehouse robots’ for biotechnology applications

Posted by in categories: biotech/medical, robotics/AI

UCLA engineers have developed minuscule warehouse logistics robots that could help expedite and automate medical diagnostic technologies and other applications that move and manipulate tiny drops of fluid. The study was published in Science Robotics.

The robots are disc-shaped magnets about 2 millimeters in diameter, designed to work together to move and manipulate droplets of blood or other fluids, with precision. For example, the robots can cleave one large droplet of fluid into smaller drops that are equal in volume for consistent testing. They can also move droplets into preloaded testing trays to check for signs of disease. The research team calls these robots “ferrobots” because they are powered by magnetism.

Stanford’s AI Index Report: How Much Is BS?

Posted by in categories: economics, engineering, health, information science, law, mobile phones, robotics/AI, sustainability, transportation

Another important question is the extent to which continued increases in computational capacity are economically viable. The Stanford Index reports a 300,000-fold increase in capacity since 2012. But in the same month that the Report was issued, Jerome Pesenti, Facebook’s AI head, warned that “The rate of progress is not sustainable…If you look at top experiments, each year the cost is going up 10-fold. Right now, an experiment might be in seven figures but it’s not going to go to nine or 10 figures, it’s not possible, nobody can afford that.”

AI has feasted on low-hanging fruit, like search engines and board games. Now comes the hard part — distinguishing causal relationships from coincidences, making high-level decisions in the face of unfamiliar ambiguity, and matching the wisdom and commonsense that humans acquire by living in the real world. These are the capabilities that are needed in complex applications such as driverless vehicles, health care, accounting, law, and engineering.

Despite the hype, AI has had very little measurable effect on the economy. Yes, people spend a lot of time on social media and playing ultra-realistic video games. But does that boost or diminish productivity? Technology in general and AI in particular are supposed to be creating a new New Economy, where algorithms and robots do all our work for us, increasing productivity by unheard-of amounts. The reality has been the opposite. For decades, U.S. productivity grew by about 3% a year. Then, after 1970, it slowed to 1.5% a year, then 1%, now about 0.5%. Perhaps we are spending too much time on our smartphones.

Are Infants Born Kind? New Research Says Yes

Posted by in category: futurism

If human infants show apparent intellectual qualities like compassion earlier than we might have expected but chimpanzees don’t, we must accept that humans are fundamentally different from chimpanzees. Conflicting definitions of altruism cloud the picture.

Why Pioneer Neurosurgeon Wilder Penfield Said the Mind Is More Than the Brain

Posted by in categories: biotech/medical, neuroscience

The patients always knew that when he stimulated their arm, it was him doing it, not them. And when they stimulated their arm, they were doing it, not him. So Penfield said, he couldn’t stimulate the will. He could never trick the patients into thinking it was them doing it. He said, the patients always retained a correct sense of agency. They always know if they did it or if he did it.

So he said the will was not something he could stimulate, meaning it was not material.

Big Tech’s honeymoon with the world’s second-largest internet market is ending

Posted by in categories: government, internet

With nearly 700 million internet users and almost an equal number of people yet to come online for the first time, India is too big a market to ignore. But the tightening of restrictions on foreign tech companies and government intervention in controlling the internet are sparking concerns that the world’s largest democracy is becoming increasingly China-esque.


In the 2010s, India’s internet exploded. More than half a billion Indians came online in the 10 years to September 2019, according to the latest government data, and the country now has twice as many internet users as the entire population of the United States.

And Big Tech rushed to cash in. Facebook ( FB ) CEO Mark Zuckerberg and Twitter ( TWTR ) CEO Jack Dorsey both visited India and met the country’s Prime Minister Narendra Modi, as did Google ( GOOGL ) CEO Sundar Pichai and Microsoft ( MSFT ) CEO Satya Nadella, both of whom were born and grew up in India. Nadella and Amazon’s Jeff Bezos both made their second visits to the country as tech CEOs earlier this year.

Human brains have ‘time cells’ that let us recall when events happened

Posted by in categories: biotech/medical, neuroscience

We have finally found time cells in the human brain – they help explain how we recall when events happened, and they could be a target for Alzheimer’s therapies.

Rare Isaac Newton manuscript discovered in Corsican library

Posted by in category: physics

A first-edition copy of Isaac Newton’s groundbreaking book laying out his three laws of motion, which became the foundation for modern physics, has been found at a library on the French island of Corsica.

Vannina Schirinsky-Schikhmatoff, director of conservation at the Fesch public heritage library in Ajaccio, said she discovered the copy of the 17th-century work while studying an index from the library’s founder Lucien Bonaparte—one of Napoleon’s brothers.

“I found the Holy Grail in the main room, hidden in the upper shelves,” she told AFP this week.

Blue Origin shows off the finished massive nose cone for its future New Glenn rocket

Posted by in category: satellites

Jeff Bezos’ aerospace company Blue Origin has completed the first nose cone of its future orbital rocket, the New Glenn — and new video of the hardware shows the true enormity of this piece of equipment. With a diameter of 7 meters, or 22 feet, the cavernous nose cone is so giant that it can completely house Blue Origin’s smaller New Shepard rocket.

The nose cone, or payload fairing, is a crucial piece of any rocket heading to space. It sits on top of the vehicle and surrounds whatever payload or satellite the rocket is carrying, acting as a shield during the ascent through the atmosphere. Once in space, the payload breaks away and exposes the satellite so that the payload can be deployed by the rocket.

Scientists discover new repair mechanism for alcohol-induced DNA damage

Posted by in category: biotech/medical

Researchers of the Hubrecht Institute (KNAW) in Utrecht, The Netherlands, and the MRC Laboratory of Molecular Biology in Cambridge, United Kingdom, have discovered a new way in which the human body repairs DNA damage caused by a degradation product of alcohol. That knowledge underlines the link between alcohol consumption and cancer. The research groups of Puck Knipscheer and Ketan J. Patel worked together on this study and published the results in the scientific journal Nature on the 4th of March.

Our DNA is a daily target for a barrage of damage caused by radiation or toxic substances such as alcohol. When alcohol is metabolized, acetaldehyde is formed. Acetaldehyde causes a dangerous kind of DNA damage—the interstrand crosslink (ICL)—that sticks together the two strands of the DNA. As a result, it obstructs and protein production. Ultimately, an accumulation of ICL damage may lead to cell death and cancer.
