New research shows that the brain‘s neuroplasticity isn’t as flexible as previously thought.

One of the brain’s mysteries is how exactly it reorganizes new #information as you learn new tasks. The standard to date was to test how neurons learned new behavior one #neuron at a time.

Carnegie Mellon University and the University of Pittsburgh decided to try a different approach. They looked at the population of neurons to see how they worked together while #learning a new behavior. Studying the intracortical population activity in the primary motor cortex of rhesus macaques during short-term learning in a brain–computer interface (BCI) task, they were able to study the reorganization of population during learning.

Re-created viruses, toxic bacteria top new ranking of risks.

Investigators at Harvard Medical School have identified the key cellular mechanisms behind vascular aging and its effects on muscle health, and they have successfully reversed the process in animals.

The scientists used a chemical compound that’s an NAD+ booster called NMN which plays a critical role in repairing cellular DNA as well as maintaining cell vitality to test what would happen.

Could reversing the aging of blood vessels hold the key to restoring youthful vitality? If the old adage “you are as old as your arteries” reigns true then the answer is yes, at least in mice.

What does it mean to fall in love in the 21st century? Originally, the number of people you could fall in love with were limited to the amount that lived within relative close proximity of you (a few miles, at best). In today’s world, however, it isn’t that uncommon for people to fall in love online.

As we move forward into a future of VR and AI, how might our abilities to fall in love change in a world where non-biological life is teeming just as much as biological life?

Using mock burglaries, researchers investigate a way to catch criminals using the microbes they leave behind. Could your microbiome give you away?

The Neurogenesis Debate

Written by Nicholi Avery

On March 7 2018, a study was published in the highly esteemed journal Nature by an international team of scientists claiming that #neurogenesis starts to rapidly decline in the #human brain as early as 13 years old and becomes undetectable in adults. This rocked the scientific community as there has been a long-established theory that neurogenesis takes place throughout the course of life in the mammalian #brain. Until the 1990s, neurologists were practicing their profession under the doctrine established in the late 19th to early 20th century by the prominent histologist Ramon y Cajal, often referred to as a god of neuroscience;

It was a good week for physics as a team with members from Australia and Switzerland invented a flux capacitor able to break time-reversal symmetry. They proposed a device based on quantum tunneling of magnetic flux around a capacitor. And another team with members from across the U.S. reported on a gravitational wave event that likely signaled the creation of a black hole—the merger of two neutron stars.

In biology news, a team of engineers led by Sinisa Vukelic invented a noninvasive technique to correct vision. Like LASIK, it uses lasers but is non-surgical and has few side-effects. And an international team of researchers found what they describe as the mother of all lizards in the Italian Alps, the oldest known lizard fossil, from approximately 240 million years ago. Also, a team at the University of Sydney found that walking faster could make you live longer. People do not even need to walk more, the team reported, they just need to pick up the pace of their normal stride to see an improvement in several health factors. And a team from Cal Poly Pomona discovered how microbes survive clean rooms and contaminate spacecraft—and it involved the cleaning agents themselves.

In other news, a team of researchers from the University of California and the University of Southern Queensland announced that they had identified 121 giant planets that may have habitable moons. And a team at Stanford University found that wars and clan structure might explain a strange biological event that occurred 7,000 years ago—male genetic diversity appeared to collapse for a time. Also, a team of researchers from MIT and Harvard University report the development of a 3D printer that can print data sets as physical objects—offering far more realistic, nearly true-color renderings.

I’ll be speaking at the exciting Future Flux Festival on the Heroes of Innovation program section on June 15 in the Netherlands. Come join me! https://www.futurefluxfestival.nl/…/heroes-of-innovation-z…/ #transhumanism

Transhumanism is the field of merging human beings with machines and radical science. The field has grown from fringe to a nearly mainstream social movement. Today, there are tens of millions of transhumanists around the world, many who are scientists and technologists focusing on overcoming biological death with innovation. The movement got a major push when Zoltan Istvan, a former journalist for National Geographic, published his bestselling philosophical novel The Transhumanist Wager. In 2016 Zoltan ran for the Presidency of the United States as the nominee of the Transhumanist Party. His campaign was broadly covered in major media for nearly two years, and it helped spearhead the transformation of transhumanism into a thriving worldwide phenomenon. Always wanted to know more about transhumanism? See you at the Future Flux Festival!

Zoltan Istvan is also part of our Heroes of Innovation panel. After their presentations you can ask our panel anything. Take a deep dive into the minds of these great innovators!

You may have forgotten about the nucleolus since you took biology class, but scientists think this structure inside every cell in your body may play an important role in aging.
