A DNA robot that can walk across biological cell membranes is the first one that can control living cells’ behaviour. The researchers who made the robot hope that it could improve cell-based precision medicine.

A team led by Hong-Hui Wang and Zhou Nie from Hunan University, China, has created a synthetic molecular robot that walks along the outer membrane of biological cells. The robot, powered by an enzyme’s catalytic activity, traverses across receptors that act as stepping stones on the cell surface. With each step, the robot activates a signal pathway that regulates cell migration. Driven by the robot’s movement, the cells can reach speeds of 24 μm/hour.

The researchers write that the DNA robot offers, for the first time, an opportunity to accurately and predictably control the nanoscale operations that power a live cell. They suggest that similar molecular machines that guide cell behaviours could play a role in cell-based therapies and regenerative medicine.

Every time I see a Bill Faloon vid I feel like it’s the most important post I make all year. A lot of information here. Plasma, transcription, stem cell human experiment, billionaires, c. elegans pathways, and and on. If you want hope about living a long time, here it is.

Basically this was found out in the 1980s and this allows for teleportation in real life 😳 😅 🙃

Wave functions for four identical spin‐one‐half fermions with total spin 0 1, and 2 are constructed. Lower bounds on the ground state energies of these spin states are derived. The results are illustrated with an.

In preparation for his journey, Stibbe was asked to choose personal items he would like to take with him into space. What he chose: A 3D-scale model of the Japanese Peace Bell.

Please be sensitive to any artificial intelligence you encounter today. A UK appeals court just ruled that AI systems cannot submit or hold patents, as software is not human and therefore lacks human rights. Several courtrooms around the world have come to the same conclusion, despite the efforts of a very enthusiastic inventor.

Dr. Stephen Thaler has repeatedly filed patents on behalf of his AI, called DABUS. He claims that this AI should be credited for the inventions that it’s helped to produce. But patent offices disagree. After Dr. Thaler refused to resubmit his patents under a real name, the UK Intellectual Property Office pulled him from the registration process.

No, but centaurs might.

Researchers have discovered how an ancient species of beetle has survived without having sex.

The Oppiella nova is a species of all female “ancient asexual” beetle mites, according to a press release from the University of Cologne. For years, scientists have struggled to figure out how exactly the creatures reproduce and survive despite not having sex. At one point, they hypothesized that the beetle mites occasionally produce a reproductive male by accident (a la “Jurassic Park”).

Now, they have cracked the elusive puzzle: the beetles can create clones of itself.

BATYGIN

Astronomer Michael Brown and astrophysicist Konstantin Batygin, both professors at the California Institute of Technology, have after years of observations completed a study postulating that an unknown new planet might exist beyond the orbit of Neptune.

A theoretical study proposes that magnetic monopoles may appear not as elementary but as emergent particles in complex, strongly-correlated magnetic systems such as spin ice, in analogy to fractional electric charges in quantum Hall systems. This theory explains a mysterious phase transition in spin ice that has been observed experimentally.
