Can you imagine if we had computer/brain interfaces what would happen? We’ll need brain firewalls and antivirus.

Android apps digitally signed by China’s third-biggest e-commerce company exploited a zero-day vulnerability that allowed them to surreptitiously take control of millions of end-user devices to steal personal data and install malicious apps, researchers from security firm Lookout have confirmed.

The malicious versions of the Pinduoduo app were available in third-party markets, which users in China and elsewhere rely on because the official Google Play market is off-limits or not easy to access. No malicious versions were found in Play or Apple’s App Store. Last Monday, TechCrunch reported that Pinduoduo was pulled from Play after Google discovered a malicious version of the app available elsewhere. TechCrunch reported the malicious apps available in third-party markets exploited several zero-days, vulnerabilities that are known or exploited before a vendor has a patch available.

One of the largest mysteries of science is that humans have conscious awareness of their complex subjective experiences – or what we call “qualia” – such as being aware of what it’s like to delight in the color of a flower, melt into the comfort of a bed, or to feel sharp pain. Why and how qualia could emerge from physical matter and be a part of the human experience is unknown, and this is called the ‘hard problem’ of consciousness. Related to qualia is the mystery of why humans feel like they have free will, or the ability to intentionally choose and execute actions.

The ‘easy’ problem of consciousness is mapping these mind states to brain states, such as identifying which brain regions are active during a certain experience, such as smelling a flower. Despite advances in classical physics and neuroscience, many aspects of the mind-brain relationship, such as qualia, remain unresolved. New theories of mind are required to address this perennial mystery.

In a new paper, we propose that some aspects of mind are quantum and can play an active role in the physical world, explaining some of the unexplainable.

The journal Nature published a groundbreaking new study by world-renowned Stanford neuroscientist Sergiu Pasca involving the transfer of human brain organoids into the brains of rats. Insoo Hyun, Director of the Center for Life Sciences and Public Learning at the Museum of Science, speaks candidly with Dr. Pasca about his research. Why did he do it? How might this uncover the mysteries of psychiatric disorders? And the Big Question we are all wondering about – can these rats ever develop “human-like” consciousness? Together they demystify the science.

Brain function is important for a good quality of life. Pyrroloquinoline quinone disodium salt (PQQ) has been proven to improve brain function and cognition in older adults (above 45 years). In this double-blind, placebo-controlled study, we investigated the effects of PQQ on cognitive function in adults aged between 20 and 65 years. PQQ (20 mg per day) was administered for 12 weeks to the participants. After 12 weeks, the participants showed improvements in composite memory and verbal memory. A further age-stratified analysis was performed. In younger adults (aged 20–40 years), PQQ improved cognitive function (cognitive flexibility, processing speed, and execution speed) after 8 weeks. Only older adults (aged 41–65 years) showed improvements in complex and verbal memory after 12 weeks. In the logistic regression analysis that included the results of all cognitive tests, the changes due to PQQ intake were observed at 8 and 12 weeks in the young and old groups, respectively.

Neurosity’s headset uses electroencephalogram technology, or EEG, to measure brain activity by placing small metal electrodes on a person’s scalp. If the electrodes detect decreased electrical activity in the brain, the Crown plays music and sounds, or pulses vibrations, hoping those actions will help the user focus.

But some developers, it seems, have taken Neurosity’s tech a step further, turning the Crown into a more traditional brain computer interface that can allow users to control a computer using only their mind.

One owner of the gadget claimed they’ve used it to drive a Tesla, moving the electric car short distances by doing some mental math, which signals to the device that the person wearing it is exerting a lot of cognitive effort.

I used to listen to classical music more. I’m going to start again. I was searching for an article that said music helps heal brain injury but I can only find ones where it’s playing instruments that does that. But the Mozart effect is healthy and relaxing.

Just another example of how much you gain by listening.

Using music to heal the brain. If you have a TBI or know someone with one like myself, music is very therapeutic. Get some nice earbuds or over the way headphones. Wired is best or get some with long battery life. I find I feel peace and relief when I listen to certain types of music.

Why neurologic music therapy should be part of standard rehabilitation care.

Who would have thought that video games are good for TBI? I play them sometimes. Time for that, and not just music.

Video games may help TBI patients recover their physical and cognitive abilities faster than traditional therapy, according to recent research.

Although they might seem like just a pleasant distraction, video games engage several parts of the brain at once and can even promote neuroplasticity.
