ROBE Array could let small companies access popular form of AI

Posted by in categories: information science, robotics/AI, supercomputing

A breakthrough low-memory technique by Rice University computer scientists could put one of the most resource-intensive forms of artificial intelligence—deep-learning recommendation models (DLRM)—within reach of small companies.

DLRM recommendation systems are a popular form of AI that learns to make suggestions users will find relevant. But with top-of-the-line training models requiring more than a hundred terabytes of memory and supercomputer-scale processing, they’ve only been available to a short list of technology giants with deep pockets.

Rice’s “random offset block embedding ,” or ROBE Array, could change that. It’s an algorithmic approach for slashing the size of DLRM memory structures called embedding tables, and it will be presented this week at the Conference on Machine Learning and Systems (MLSys 2022) in Santa Clara, California, where it earned Outstanding Paper honors.

Maersk Earmarks $2.1 Billion for Ships That Will Run on Methanol

Posted by in categories: energy, transportation

You are looking at a methanol-fed hydrogen fuel cell that may soon be powering marine shipping around the world.


For Maersk, the 12 new ships will help it reduce CO2 emissions by 1.5 million tons annually or 4% of what the company produced in total in 2021. Maersk’s announced commitment is for all future new builds to only burn carbon-neutral fuels. That’s why fuel cells are high on its list of technologies to make that achievement possible.

Methanol Fuel Cells Are a Step Better Than Burning Methanol

Smoking Is Even More Damaging to the Heart Than Thought

Posted by in category: government

According to a new study presented at the European Society of Cardiology’s ESC Congress 2022, smokers have weaker hearts than non-smokers. [1] The research found that the more people smoked, the worse their heart function became. Fortunately, some function was restored when people kicked the habit.

Alzheimer’s Breakthrough: A New Genetic Link Confirmed

Posted by in categories: biotech/medical, genetics, neuroscience

The groundbreaking research that established the connection between Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.

Brief Exposure to Rapamycin Has the Same Anti-aging Effects as Lifelong Treatment

Posted by in categories: biotech/medical, life extension

Summary: Brief exposure to Rapamycin, a promising anti-aging drug that has positive effects on health and lifespan, has the same effect as long-term exposure to the drug in animal models. The findings pave the way for testing the effects of short-term rapamycin exposure on the lifespan of humans.

Imagine you could take a medicine that prevents the decline that come with age and keeps you healthy. Scientists are trying to find a drug that has these effects.

Marijuana use is outpacing cigarette use for the first time on record

Posted by in category: futurism

More people in the U.S. are now smoking marijuana than cigarettes, according to a Gallup poll.

Cigarette use has been trending downward during the past decades, with only 11% of Americans saying they smoke them in a poll conducted July 5 to 26, compared to 45% in the mid-1950s.

Sixteen percent of Americans say they smoke marijuana, with 48% saying they have tried it at some point in their lives. In 1969, only 4% of Americans said they smoked marijuana.

Astronomers at Western Sydney University have discovered one of the biggest black hole jets in the sky.

Spanning more than a million light years from end to end, the jet shoots away from a black hole with enormous energy, and at almost the speed of light. But in the vast expanses of space between galaxies, it doesn’t always get its own way.

New Magnet is Powerful Enough to Lift an Aircraft Carrier

Posted by in categories: military, nuclear energy

Less than a week after a Bill Gates-backed MIT startup announced it had successfully tested a massive magnet that could allow them to achieve “net energy” with their nuclear fusion reactor, scientists at France’s International Thermonuclear Experimental Reactor (ITER) received the first part of another huge magnet, an AP report explains.

That magnet is so strong that its American manufacturer claims it can lift an aircraft carrier. When it is fully assembled it will be almost 60 feet (20 meters) tall and 14 feet (over four meters) in diameter, and it could be the key to providing practically limitless energy via nuclear fusion.

Optical detection of multiple bacterial species using nanometer-scaled metal-organic hybrids

Posted by in categories: chemistry, food, nanotechnology, particle physics

Osaka Metropolitan University scientists have developed a simple, rapid method to simultaneously identify multiple food poisoning bacteria, based on color differences in the scattered light by nanometer-scaled organic metal nanohybrid structures (NHs) that bind via antibodies to those bacteria. This method is a promising tool for rapidly detecting bacteria at food manufacturing sites and thereby improving food safety. The findings were published in Analytical Chemistry.

According to the World Health Organization (WHO), every year food poisoning affects 600 million people worldwide—almost 1 in every 10 people—of which 420,000 die. Bacterial tests are conducted to detect food poisoning bacteria at food manufacturing factories, but it takes more than 48 hours to obtain results due to the time required for a bacteria incubation process called culturing. Therefore, there remains a demand for rapid testing methods to eliminate food poisoning accidents.

Responding to this need, the research team led by Professor Hiroshi Shiigi at the Graduate School of Engineering, Osaka Metropolitan University, utilized the optical properties of organic metal NHs—composites consisting of polyaniline particles that encapsulate a large number of metal nanoparticles—to rapidly and simultaneously identify food poisoning-inducing bacteria called enterohemorrhagic Escherichia coli (E. coli O26 and E. coli O157) and Staphylococcus aureus.
