Algae-powered computer runs for a year on light and water

Posted by in category: computing

An algae-powered computer: Researchers from the University of Cambridge and British tech company Arm have now demonstrated a different source of power for IoT devices: algae.

For their study, published in the journal Energy & Environmental Science, the team built a container about the size of a AA battery out of aluminum and clear plastic. They then filled it with water and algae that use photosynthesis to harvest energy from sunlight.

That process produces a small electric current. An electrode in the device uses that current to power a tiny computer processor commonly used in IoT devices.

Want a Good Reason to Capture Carbon Dioxide? — Use It to Power the Electrical Grid

Posted by in category: nuclear energy

Steam turbines could be replaced by pressurized carbon dioxide (CO2) closed-loop systems to spin turbines.


Steam turbines in thermal power generation are today’s standard. But pressurized carbon dioxide (CO2) in a closed-loop system could do the job. Supercritical CO2 acting as both a liquid and a gas under extreme pressure would provide the impetus to spin a turbine. Using supercritical CO2 may prove to be far more efficient than steam to provide emissions-free power to the electrical grid. Energy input coming from renewable sources such as wind, solar, geothermal, as well as nuclear power, or even gas or coal-fired thermal energy power plants with accompanying carbon capture technology could be combined with this technology to be an effective addition to energy utilities.

Recently researchers at the Sandia National Laboratory Kirtland Air Force Base in the United States demonstrated a closed-loop Brayton Cycle engine technology as it delivered power to the electrical grid continuously. Sandia has been working with the Brayton Cycle technology for power generation for some time now because it is seen as having significant energy conversion advantages over conventional steam turbines by as much as 50%.

Mark Zuckerberg announces launch of new VR headsets costing $1000 in Oct

Posted by in category: futurism

Mark Zuckerberg has announced Meta’s new VR headset that will cost around UDS 1,000.

While speaking to Joe Rogan in his podcast, Zuckerberg announced that the new headsets will be out this October.

Zuckerberg referred to the company’s Project Cambria, a higher-end VR and mixed-reality headset than the current Quest 2 that uses advanced eye-and facial-tracking features to more naturally represent the wearer’s expressions and body language.

Scientists Grow “Synthetic” Embryo With Brain and Beating Heart — Without Eggs or Sperm

Posted by in categories: biotech/medical, neuroscience

We have arrived at Aldous Huxleys Brave new world.


Scientists from the University of Cambridge have created model embryos from mouse stem cells that form a brain, a beating heart, and the foundations of all the other organs of the body. It represents a new avenue for recreating the first stages of life.

The team of researchers, led by Professor Magdalena Zernicka-Goetz, developed the embryo model without eggs or sperm. Instead, they used stem cells – the body’s master cells, which can develop into almost any cell type in the body.

Metformin & Rapamycin Show Combined Benefits in New Study

Posted by in categories: biotech/medical, life extension

They boost each other and block side effects? (In mice)


Rapamycin and metformin are viewed by many as the two most promising anti-aging drugs, but now scientists have found that these drugs can work hand in hand and show combined benefits, boosting each other’s effectiveness and blocking side effects — or at least that’s what we’ve seen in mice.
