Some scientists believe that the ability of animals to store memory came from a virus that infected a common ancestor hundreds of millions of years ago. đ
This study is radically changing how we view the process of evolution.

Restoration of lost motor function after stroke is typically accomplished after strenuous rehabilitation therapy lasting for over months. However, new research published by a group led by Yukio Nishimura, the project leader of the Neural Prosthesis Project, Tokyo Metropolitan Institute of Medical Science showed that an artificial neural connection (ANC)*1 successfully allowed a new cortical site, previously unassociated with hand movements, to regain control of a paralyzed hand in a matter of minutes.
In this research, experimental animals regained voluntary control of a paralyzed hand about ten minutes after establishment of an ANC. Animals engaged in learning with a functional ANC showed variable levels of input signals provided by the cerebral cortex*2 as hand movement improved. Specifically, the activated area of the cortex became more focused as control of hand movements improved.
Through this training of various areas of the cerebral cortex, the research team successfully imparted a new ability to control paralyzed hands via an ANC, even if those areas were not involved in hand control prior to the stroke. Examples of such regions include areas of the cortex that controls the movement of other body parts such as the face or shoulder, and even the somatosensory cortex, which is responsible for tactile and proprioception processing and is normally not associated with motor control. This finding suggests that an ANC can impart new motor control functions to any cortical region.
This is the TMC DUMONT, which is a concept art motorcycle, designed and built by Retired F1 driver and designer Tarso Marques.
This ultra sleek, hubless wheel, motorcycle, is powered by an actual 300 hp, six-cylinder, Rolls-Royce Continental Aircraft Engine from 1960.

Superconductivity is a phenomenon where an electric circuit loses its resistance and becomes extremely efficient under certain conditions. There are different ways in which this can happen which were thought to be incompatible. For the first time, researchers discover a bridge between two of these methods to achieve superconductivity. This new knowledge could lead to a more general understanding of the phenomena, and one day to applications.
If youâre like most people, there are three states of matter in your everyday life: solid, liquid, and gas. You might be familiar with a fourth state of matter called plasma, which is like a gas that got so hot all its constituent atoms came apart, leaving behind a super hot mess of subatomic particles. But did you know about a so-called fifth state of matter at the complete opposite end of the thermometer? Itâs known as a Bose-Einstein condensate (BEC).
âA BEC is a unique state of matter as it is not made from particles, but rather waves,â said Associate Professor Kozo Okazaki from the Institute for Solid State Physics at the University of Tokyo. âAs they cool down to near absolute zero, the atoms of certain materials become smeared out over space. This smearing increases until the atoms â now more like waves than particles â overlap, becoming indistinguishable from one another. The resulting matter behaves like itâs one single entity with new properties the preceding solid, liquid or gas states lacked, such as superconduction. Until recently superconducting BECs were purely theoretical, but we have now demonstrated this in the lab with a novel material based on iron and selenium (a nonmetallic element).â
Ryu kidding?
Earlier this week it emerged that third-party giant Capcomâs internal systems had been hacked, though the company claimed that no customer data was affected. It has now emerged that the publisher was targeted by the Ragnar Locker ransomware, software designed to exfiltrate information from internal networks before encrypting the lot: at which point the victim is locked-out, contacted, and extorted.
Bleeping Computer broke the story, and managed to access the Ragnar Locker sample (a âproofâ provided to the victim by the hackers), which contains the ransom note allegedly delivered to Capcom. It reads as follows.

Summary: Researchers have discovered a two-pronged approach to restore myelin on regenerated axons in a mouse model of optic nerve damage. The findings have positive implications for the treatment of multiple sclerosis.
Source: Childrenâs Hospital of Boston
Loss of myelinâthe fatty substance that surrounds the axons of nerve cellsâis one of the reasons nerve cells fail to recover after injury and in some diseases. Myelin acts like insulation, covering the long axon threads that enable high-speed communication between neurons. Without myelin, the neurons may not be able to coordinate well, leading to less than optimal function.
Neuroscientists at University College London (UCL) have used laser beams to âswitch onâ neurons in mice, providing new insight into the hidden workings of memory and showing how memories underpin the brainâs inner GPS system.
The study, published in the journal Cell, explains how researchers harnessed an âall-opticalâ approach using twin lasers to simultaneously read and write the activity of âplace cellsâ (a type of neuron) in mice, as they navigated a virtual reality environment.
Remarkably, by stimulating the place cells, scientists were able to reactivate (or retrieve) the memory of a location where the mice obtained a reward, which in turn âmentally teleportedâ the mice, causing them to act as if they were in the rewarded place.
It seems solar power is really benefiting these chicken farmers from Australia. It allows them to slash their electricity bill.
This 10-million-bird chicken farm has slashed its power bill and reduced its CO2 emissions by 1,500 tonnes after installing one of agricultureâs most extensive solar and battery systems.
