Robots with insect brains

Posted by in categories: genetics, habitats, neuroscience, robotics/AI

It is an engineer’s dream to build a robot as competent as an insect at locomotion, directed action, navigation, and survival in complex conditions. But as well as studying insects to improve robotics, in parallel, robot implementations have played a useful role in evaluating mechanistic explanations of insect behavior, testing hypotheses by embedding them in real-world machines. The wealth and depth of data coming from insect neuroscience hold the tantalizing possibility of building complete insect brain models. Robotics has a role to play in maintaining a focus on functional understanding—what do the neural circuits need to compute to support successful behavior?

Insect brains have been described as “minute structures controlling complex behaviors” (1): Compare the number of neurons in the fruit fly brain (∼135,000) to that in the mouse (70 million) or human (86 billion). Insect brain structures and circuits evolved independently to solve many of the same problems faced by vertebrate brains (or a robot’s control program). Despite the vast range of insect body types, behaviors, habitats, and lifestyles, there are many surprising consistencies across species in brain organization, suggesting that these might be effective, efficient, and general-purpose solutions.

Unraveling these circuits combines many disciplines, including painstaking neuroanatomical and neurophysiological analysis of the components and their connectivity. An important recent advance is the development of neurogenetic methods that provide precise control over the activity of individual neurons in freely behaving animals. However, the ultimate test of mechanistic understanding is the ability to build a machine that replicates the function. Computer models let researchers copy the brain’s processes, and robots allow these models to be tested in real bodies interacting with real environments (2). The following examples illustrate how this approach is being used to explore increasingly sophisticated control problems, including predictive tracking, body coordination, navigation, and learning.

Hallucinogenic effects of LSD discovered

Posted by in categories: habitats, neuroscience

Last Friday, April 16, 1943, I was forced to interrupt my work in the laboratory in the middle of the afternoon and proceed home, being affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant, intoxicated-like condition characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away.

As more work from home, Dell unveils new BIOS shield

Posted by in categories: business, cybercrime/malcode, habitats

As millions of employees are suddenly working from home, computer security threats are on the rise. The sudden rush to set up home offices means many users working on insufficiently protected devices are exposing businesses to unprecedented new exposure to malicious hackers.

“While the world is grinding to a halt, cyber-attacks are on the rise, preying on public fear and anxiety,” says Yenni Tim, researcher of Cybersecurity at the University of New South Wales Business School in Sydney, Australia.

In an effort to combat , Dell Technologies last week released a utility that will protect one of the most sensitive components of a computer, the BIOS. Frequently the target of the most malicious malware assaults, the BIOS oversees critical computer processes, from boot-up to system configuration parameters.

NASA’s Offering Online Astronaut Training While You’re Stuck in Lockdown

Posted by in categories: habitats, space travel

Who hasn’t dreamt of escaping to the stars? Especially now, with most of us confined to limited spaces and steeped in tragic news.

NASA and the ISS National Lab are ready to help. They’ve developed a range of adventurous programs and activities for all the children stuck in home lockdown, including a training program to become a home astronaut, build a hovercraft, launch rockets, and many more.

The Next Economic Meltdown Will Transfix The Real Estate Market As We Know It

Posted by in categories: economics, finance, habitats

Are we in for the Big Short II? The cyclical nature of markets spells an eventual collapse of the real estate prices in the U.S. following the next global stock market meltdown and global recession which will be drastically different the next time around. For one, the coming collapse is about to start a secular declining trend in property values. Secondly, after the collapse, the prices of properties won’t be able to recover like they did after the previous “property market corrections.”

Why? I hope we all may agree that oil, for example, will never recover to all-time highs. Similar premises hold true for the existing home values. There are multiple major socio-economic structural changes on the horizon contributing to this permanent decline which is in the cards right now. Also, many conventional linear projections won’t even apply anymore.

THE NEXT “CYCLICAL” GLOBAL RECESSION — the world’s stock markets are the best indication of things to come in the economic milieu. The next financially engineered global recession may be the last effort by the capital-controlling elite of Wall Street to keep political and economic control over the global population and maintain the faltering capitalist system as long as possible;

Singapore could have a floating city to house 50,000 people

Posted by in categories: governance, habitats

Singapore’s floating city could be real in 10 years.

Do you feel like Singapore is getting more crowded by the day? Apartment blocks are rising quickly everywhere, yet securing a home is still difficult for many.

Our land shortage problem is an age-old conundrum and having taller buildings isn’t going to help much anymore.

All rough sleepers in England ‘to be housed’

And just like that, the homeless were given homes! ❤.

Labour have welcomed the plan but said councils “need more support” and money to achieve it.

La Maison De La Celle-Saint-Cloud’ Art Installation

Posted by in categories: habitats, space

‘La Maison de La Celle-Saint-Cloud’ is an art installation from 1974, in a house built by French artist, Jean Pierre Raynaud. Fascinated by space, uniformity and identity, he began to build this house in 1969 using entirely white tiles with black grout, creating the regular grid pattern in a rigid and geometric form. In 1974, the house was opened to the public in Paris showing the ultimate perfection and flawlessness. But then in 1988, the artist decided to closed the house to himself only and subsequently demolished it in 1993 and presented the debris in 976 surgical containers.

The life of La Maison didn’t stop there, the fragments of which, have since been exhibited in various installations, and the fashion industry has also been paying tribute to it with different ad campaigns and collections inspired by the house.
