Scientists Discover Creature That Never Has Sex

Posted by in category: sex

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.

A new planet? Astronomers believe they’ve found proof

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.

Magnetic monopoles in spin ice

Posted by in categories: particle physics, quantum physics

Circa 2008


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.

Magnetricity near the speed of light

Posted by in categories: mathematics, nanotechnology, physics

Circa 2012


Faraday and Dirac constructed magnetic monopoles using the practical and mathematical tools available to them. Now physicists have engineered effective monopoles by combining modern optics with nanotechnology. Part matter and part light, these magnetic monopoles travel at unprecedented speeds.

In classical physics (as every student should know) there are no sources or sinks of magnetic field, and hence no magnetic monopoles. Even so, a tight bundle of magnetic flux — such as that created by a long string of magnetic dipoles — has an apparent source or sink at its end. If we map the lines of force with a plotting compass, we think we see a magnetic monopole as our compass cannot enter the region of dense flux. In 1,821 Michael Faraday constructed an effective monopole of this sort by floating a long thin bar magnet upright in a bowl of mercury, with the lower end tethered and the upper end free to move like a monopole in the horizontal plane.

Samsung hopes to ‘copy and paste’ the brain to 3D chip networks

Posted by in category: robotics/AI

Samsung thinks it has a better way to develop brain-like chips: borrow existing brain structures. The tech firm has proposed a method that would “copy and paste” a brain’s neuron wiring map to 3D neuromorphic chips. The approach would rely on a nanoelectrode array that enters a large volumes of neurons to record both where the neurons connect and the strength of those connections. You could copy that data and ‘paste’ it to a 3D network of solid-state memory, whether it’s off-the-shelf flash storage or cutting-edge memory like resistive RAM.

Each memory unit would have a conductance that reflects the strength of each neuron connection in the map. The result would be an effective return to “reverse engineering the brain” like scientists originally wanted, Samsung said.

The move could serve as a ‘shortcut’ to artificial intelligence systems that behave like real brains, including the flexibility to learn new concepts and adapt to changing conditions. You might even see fully autonomous machines with true cognition, according to the researchers.

Zydus Cadila: What we know about India’s new Covid vaccines

Posted by in categories: biotech/medical, genetics

The ZyCoV-D vaccine is also the world’s first DNA vaccine against Covid-19.

Like other vaccines, a DNA vaccine, once administered, teaches the body’s immune system to fight the real virus.

ZyCoV-D uses plasmids — or small rings of DNA that contain genetic information — to deliver the jab between two layers of the skin.
