Manufacturing microscopic octopuses with a 3D printer

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

Although just cute little creatures at first glance, the microscopic geckos and octopuses fabricated by 3D laser printing in the molecular engineering labs at Heidelberg University could open up new opportunities in fields such as microrobotics or biomedicine.

The printed microstructures are made from —known as smart polymers—whose size and can be tuned on demand and with high precision. These “life-like” 3D microstructures were developed in the framework of the “3D Matter Made to Order” (3DMM2O) Cluster of Excellence, a collaboration between Ruperto Carola and the Karlsruhe Institute of Technology (KIT).

“Manufacturing programmable materials whose mechanical properties can be adapted on demand is highly desired for many applications,” states Junior Professor Dr. Eva Blasco, group leader at the Institute of Organic Chemistry and the Institute for Molecular Systems Engineering and Advanced Materials of Heidelberg University.

How the metaverse (and quantum physics) could prove our universe is a fake

Posted by in category: quantum physics

Our universe is a ridiculous place. It’s where all the silliest things we’re aware of happen. And chief among the silliness is the wacky idea of…

65 years ago, “simple satellite” Sputnik redefined space science — and sent a sinister message

Posted by in categories: military, satellites, science

There was more to this launch than met the eye.


Earth’s first-ever artificial satellite Sputnik launched on October 4, 1957. In that moment, which occurred sixty-five years ago, the Cold War between the United States and the Soviet Union transformed into a race to dominate not only Earth but also space.

But there was more to the launch than met the eye — behind the development of satellites to orbit Earth was a more nefarious purpose.

Largest combined wind/solar/battery plant opens in U.S.

Posted by in categories: energy, sustainability

Portland General Electric (PGE), a public utility, has partnered with NextEra Energy Resources to create a 350 megawatt (MW) clean energy project that combines wind, solar, and battery storage. Wheatridge Renewable Energy Facility, located at the northern edge of Oregon, has the capacity to serve 100,000 homes.

Although great progress is being made with scaling up renewables, intermittency remains a significant issue – since wind does not always blow, and the Sun does not always shine. Falling costs and improvements in technology mean that batteries are increasingly a realistic option for utilities, but we are still a long way from such systems being able to fully handle the demands of national electrical grids.

The newly operational Wheatfield facility is among the most notable advances in battery storage to date in the U.S. It consists of 120 turbines (a mix of 2.3 MW and 2.5 MW machines) generating 300 MW, alongside a 50 MW photovoltaic solar array, for a total of 350 MW. An accompanying battery storage facility is charged using power from the grid and provides 30 MW of continuous power for four hours, i.e. 120 megawatt-hours (MWh). When combined, this is enough to supply nearly 60% of the power generated by the Boardman Coal Plant, which became the last coal-fired plant in Oregon before its demolition a few weeks ago.

A breakthrough in metastasis could lead to better cancer treatments

Posted by in categories: biotech/medical, genetics

Understanding how metastasis works.

In the universal fight against cancer, metastasis is one of the most unpleasant factors that could make matters even worse; and there is still much to comprehend in the spread process. Cambridge scientists might have unveiled a breakthrough in understanding how metastasis works.

The research has been published in the journal Nature Genetics.

Stanford researchers produce a groundbreaking cancer-fighting compound

Posted by in categories: biotech/medical, chemistry

The researchers brilliantly demonstrated, for the very first time, how to chemically transform an abundant, plant-based starting material into EBC-46.

In what can be called a major scientific breakthrough, Stanford researchers have discovered a “rapid and sustainable” way to synthetically produce a promising cancer-fighting compound, designated EBC-46, right in the lab, according to a press release published by the institution.

This was “something many people had considered impossible,” as the compound’s only currently known source is a single plant species that grows solely in a small rainforest region of Northeastern Australia.
