West makes plans to avoid panic if Russia uses nuclear bomb in Ukraine

Posted by in category: military

Its still too early for nukes. i expect some weird event to escalate into a full scale conventional war between Russia vs. Nato; Russia will attempt an invasion into europe. When that takes place China decides might as well try an invasion across asia. India will be issue in doubt. All ^ above will last 3 to 6 months. Nukes will be end of it, when it takes place, ignore Anyone tellin you to Stay Inside of a blast zone, and run.


Western officials are engaged in “prudent planning” behind the scenes to prevent chaos and panic in their home countries in the event Russia was to detonate a nuclear bomb in or near Ukraine.

Although a nuclear crisis is considered highly unlikely, the insider said officials internationally were re-examining plans to provide emergency support and reassurance to populations fearful of nuclear escalation.

Electroporation and cell killing

Posted by in category: futurism

All strength-duration curves expectedly climbed as pulse duration decreased (Fig. 9 A). The nerve stimulation thresholds rose much faster (similar to findings with H-FIRE17), thereby decreasing the ratio of cell killing and excitation thresholds for shorter pulses (Fig. 9 B). Nanosecond pulses showed a profound and unequivocal advantage over conventional 100-µs pulses: The ratio of cell killing and excitation thresholds dropped from as high as 500 for unipolar 100-µs pulses to 13 for unipolar 150-ns pulses. Engaging bipolar cancellation further decreased this ratio to only 4 for bipolar 150 ns pulses (Fig. 9 B). Thus, bipolar nanosecond pulses are the best choice for the reduction of neuromuscular stimulation from PEF ablation.

The stimulation boundaries for ablation with different pulse durations and shapes are illustrated by a hypothetical example in Fig. 10. Based on data in Fig. 9 and numerical simulations of the electric field distribution, we explored how far electrostimulation will reach from an ablation area. A tumor 0.7 cm in diameter was placed between two needle electrodes (0.5-cm diameter, 1.7-cm center-to-center distance) for ablation by PEF, and 300 pulses were delivered at the minimum amplitude needed for tumor ablation. Nerve stimulation occurred within a range of about 2 cm for bipolar 200-ns pulses, but as far as 20 cm away for unipolar 100-µs pulses.

Brain cells in a lab dish learn to play Pong — and offer a window onto intelligence

Posted by in categories: computing, entertainment, neuroscience

A dish of living brain cells has learned to play the 1970s arcade game Pong.

About 800,000 cells linked to a computer gradually learned to sense the position of the game’s electronic ball and control a virtual paddle, a team reports in the journal Neuron.

The novel achievement is part of an effort to understand how the brain learns, and how to make computers more intelligent.

Mark Zuckerberg said he missed a giant shift in social networking

Posted by in category: futurism

Meta CEO Mark Zuckerberg failed to anticipate a newer trend in social networking that contributed to the success of rival TikTok.

In an interview published Wednesday in analyst Ben Thompson’s Statechery newsletter, the Facebook founder said he “sort of missed” a newer way that people “interact with discovered content” via social networking services. People are increasingly using their social networking “feeds” to discover compelling content as opposed to viewing the media shared by the friends that they follow, he explained.

Although people still interact with content that their friends share in their feeds, the overall social networking trend has “by and large shifted to you use your feed to discover content, you find things that are interesting, you send them to your friends in messages and you interact there,” Zuckerberg said.

Experimental Cancer Drug Reverses Schizophrenia in Adolescent Mice

Posted by in categories: biotech/medical, neuroscience

O.o!!!.


Johns Hopkins researchers say that an experimental anticancer compound appears to have reversed behaviors associated with schizophrenia and restored some lost brain cell function in adolescent mice with a rodent version of the devastating mental illness.

The drug is one of a class of compounds known as PAK inhibitors, which have been shown in animal experiments to confer some protection from brain damage due to Fragile X syndrome, an inherited disease in humans marked by mental retardation. There also is some evidence, experts say, suggesting PAK inhibitors could be used to treat Alzheimer’s disease. And because the PAK protein itself can initiate cancer and cell growth, PAK inhibitors have also been tested for cancer.

Music Was Just Encoded on DNA and Retrieved for the First Time

To demonstrate this, researchers stored historic audio recordings on these molecules for the first time and then retrieved them with 100 percent accuracy. The experiment showed that DNA not only offers a place to save a dense package of information in a tiny space, but because it can last for hundreds of years, it reduces the risk that it will go out of date or degrade in the way that cassette tapes, compact discs, and even computer hard drives can.

“DNA is intrinsically and exquisitely a stable molecule,” Emily Leproust, CEO of the biotech firm Twist Bioscience, which works on DNA synthesis, told Seeker. Her company collaborated with Microsoft, the University of Washington, and the Montreux Jazz Digital Project on the DNA data feat.

Philanthropist Boris Zimin Shares His Perspective On Modern Education

Posted by in categories: education, ethics

I had quite a thought-provoking discussion on modern education with Boris Zimin, the head of the Zimin Foundation, which funds education and research.


The Zimin Foundation is a non-profit organization established by the Zimin family to aid education and science. The Foundation partners with distinguished universities and funds research and educational projects that combine academic excellence with high potential for positive, real-world impact. Since the start of the Russian invasion of Ukraine, the Zimin Foundation has been supporting researchers and students affected by the war. I spoke with philanthropist Boris Zimin, the head of the Zimin Foundation, about his perspective on modern education.

Julia Brodsky: From your experience working with various educational funds and organizations, what do you think should be the emphasis of modern education?

What lab-grown ‘mini-brains’ are revealing about this mysterious organ

Posted by in categories: biotech/medical, neuroscience

Blobs of human brain cells cultivated in the lab, known as brain organoids or “mini-brains”, are transforming our understanding of neural development and disease. Now, researchers are working to make them more like the real thing.

Neuroscientist leads unprecedented research to map billions of brain cells

Circa 2018 face_with_colon_three


Since the time of Hippocrates and Herophilus, scientists have placed the location of the mind, emotions and intelligence in the brain. For centuries, this theory was explored through anatomical dissection, as the early neuroscientists named and proposed functions for the various sections of this unusual organ. It wasn’t until the late 19th century that Camillo Golgi and Santiago Ramón y Cajal developed the methods to look deeper into the brain, using a silver stain to detect the long, stringy cells now known as neurons and their connections, called synapses.

Today, neuroanatomy involves the most powerful microscopes and computers on the planet. Viewing synapses, which are only nanometers in length, requires an electron microscope imaging a slice of brain thousands of times thinner than a sheet of paper. To map an entire human brain would require 300,000 of these images, and even reconstructing a small three-dimensional brain region from these snapshots requires roughly the same supercomputing power it takes to run an astronomy simulation of the universe.
