Soyuz 11: Disaster in Space

Posted by in categories: media & arts, space

Soyuz 11 was the only crewed mission to board the world’s first space station, Salyut 1. The crew, Georgy Dobrovolsky, Vladislav Volkov, and Viktor Patsayev, arrived at the space station on 7 June 1971 and departed on 29 June. The mission ended in disaster when the crew capsule depressurized during preparations for reentry, killing the three-man crew. The three crew members of Soyuz 11 are the only humans known to have died in space.

Russia’s biggest lender Sberbank wants to transform into Big Tech company

Posted by in categories: finance, robotics/AI

In a major strategy shift, Sberbank, the most popular Russian lender, wants to build its own ecosystem going far beyond the world of finance and to be known not just as a bank, but also as a tech company.


During its first major online event, which was held on Thursday, Sberbank – now rebranded as Sber – presented a range of services and gadgets signaling it wants to go deeper into the tech sector. For example, the bank presented a family of “emotional” virtual assistants, called ‘Salute’, which will be incorporated into all of Sberbank’s devices and mobile apps.

There are three assistants in the Salute family, called Sber, Joy, and Athena. Unlike Apple’s Siri or Amazon’s Alexa, the company is betting on the “emotional” features of the virtual assistants, as each has its own “temper,” allowing users to choose the one they find most suitable.

Tone of voice matters in neuronal communication

Posted by in categories: biotech/medical, neuroscience

WOODS HOLE, Mass. — The dialogue between neurons is of critical importance for all nervous system activities, from breathing to sensing, thinking to running. Yet neuronal communication is so fast, and at such a small scale, that it is exceedingly difficult to explain precisely how it occurs. A preliminary observation in the Neurobiology course at the Marine Biological Laboratory (MBL), enabled by a custom imaging system, has led to a clear understanding of how neurons communicate with each other by modulating the “tone” of their signal, which previously had eluded the field. The report, led by Grant F. Kusick and Shigeki Watanabe of Johns Hopkins University School of Medicine, is published this week in Nature Neuroscience.

In 2016 Watanabe, then on the Neurobiology course faculty, introduced students to the debate over how many synaptic vesicles can fuse in response to one action potential (see this 2-minute video for a quick brush-up on neurotransmission). To probe this controversy, they used a “zap-and-freeze” imaging technology conceived by co-authors M. Wayne Davis, Watanabe and Erik Jorgensen, and built by Leica for testing in the Neurobiology course. They zapped a neuron with electricity to induce an action potential, then quickly froze the neuron and took an image. They saw multiple vesicles fusing at once at many synapses, the first novel finding of this Nature Neuroscience report.

Water where you need it

Posted by in category: futurism

In 2018, Cody Friesen, PhD ’04, trekked through the bush in Kenya’s Rift Valley to comprehend the perils the girls of the Samburu Girls Foundation faced when they went out to gather water.

Every day, girls living at the rescue organization had to walk two miles—often past men who see them as property—to the nearest water in a land where the past decade had been marked by blistering droughts.

There, on the muddy banks of a river riddled with cholera, Friesen saw the tracks of hyenas and men, reminders of what might await any girl who lingered.

Ransomware reportedly to blame for outage at US hospital chain

Posted by in categories: biotech/medical, health, mobile phones

It doesn’t appear staff or patient information was compromised.


Health care provider Universal Health Services, one of the largest chains in the US, has been hit by an apparent ransomware attack, TechCrunch reported. UHS facilities in California, Florida, North Dakota, Arizona, and other locations began noticing problems early Sunday, with some locations reporting locked computers and phone systems.

Some UHS hospitals had to use pen and paper to file patient information as a result, according to NBC News.
