Amazon Pulls 2 Books That Promote Unscientific Autism ‘Cures’

Posted by in categories: biotech/medical, neuroscience, sex

Good for Amazon.


Amazon has removed the online listings for two books that claim to contain cures for autism, a move that follows recent efforts by several social media sites to limit the availability of anti-vaccination and other pseudoscientific material.

The books, “Healing the Symptoms Known as Autism” and “Fight Autism and Win,” which had previously been listed for sale in Amazon’s marketplace, were not available on Wednesday. The company confirmed that the listings had been removed, but declined to discuss why or whether similar books would be taken down in the future.

Serotonin can regulate gene expression inside neurons

Posted by in categories: biotech/medical, neuroscience

“Our findings represent a dramatic divergence from the current dogma, which works primarily on the premise that neurotransmitters like serotonin and dopamine act solely through the activation of their membrane receptors in the brain to regulate brain cell activity,” says Ian Maze, PhD, Assistant Professor of Neuroscience, and Pharmacological Sciences, at the Icahn School of Medicine at Mount Sinai, and senior author of the paper. “We found actions of these brain chemicals that are independent of neurotransmission but critically important to their overall signaling, suggesting that our current understanding of these molecules is incomplete and requires further investigation.”


Findings could fundamentally change how scientists interpret the biological activities of serotonin.

UDrone: Drone with Brain & Gesture Control

Posted by in categories: drones, neuroscience

Meet the UDrone: a clever quadcopter that you can control with your thoughts or simple hand gestures. You can activate its camera by blinking or making the “V” hand gesture. The drone has subject & facial tracking, 3 adjustable speed settings, and an auto-flight control system.

The UDrone is easy to use: simply imagine it taking off and once you are concentrated enough, the drone will take off. It has mobile app control too.

Axolotl’s Regeneration Genes Also Present in Humans

Posted by in categories: biological, neuroscience

Scientists at the Marine Biological Laboratory (MBL) have identified gene “partners” in the axolotl salamander that, when activated, allow the neural tube and associated nerve fibers to functionally regenerate after severe spinal cord damage. Interestingly, these genes are also present in humans, though they are activated in a different manner. Their results are published this week in Nature Communications Biology.

Electrically syncing up brain regions improves depression in first-of-its-kind study

Posted by in categories: biotech/medical, neuroscience

In a first-of-its-kind study from researchers at the University of North Carolina (UNC) School of Medicine, a new kind of non-invasive electrical brain stimulation has been trialed in patients with major depression. The results show this new technique to be extraordinarily promising in reducing depressive symptoms, with larger trials set to explore this novel treatment in greater detail.

A Drone You Control With Your Mind Is About to Hit Kickstarter

Posted by in categories: drones, neuroscience

A Kickstarter campaign is launching on Tuesday for a drone you control with your mind.

The mind-controlled drone is the work EEGSmart, a Chinese company focused on the development of brain-machine interface (BMI) technology — and according to New Atlas writer Loz Blain, who got a chance to test the device, “It’s not perfect, but it does give a glimpse of a mind-controlled future.”

Promising compound selectively kills brain cancer stem cells

Posted by in categories: biotech/medical, neuroscience

Scripps Research scientists have discovered a compound that potently and selectively kills the stem-like cells that make glioblastoma brain cancers so deadly.

In a study published this week in The Proceedings of the National Academy of Sciences, the Scripps Research scientists found that the new compound, which they dubbed RIPGBM, kills stem-like cells cultured from patients’ tumors with more than 40 times the potency of the standard GBM drug . They found too that RIPGBM is highly selective, sparing other types of cells, and that it powerfully suppresses the growth of GBM tumors in a mouse model of the disease.

“Our discovery of this compound and the cellular pathways it affects offers a promising new strategy for treating glioblastoma,” says principal investigator Luke Lairson, PhD, an assistant professor of chemistry at Scripps Research.

Alzheimer’s disease can be spotted through simple eye test

Posted by in categories: biotech/medical, neuroscience

Alzheimer’s disease may soon be spotted through a simple eye test, after scientists discovered tell-tale alterations in the retina and blood vessels when dementia is present.

Currently diagnosing Alzheimer’s is tricky, requiring an expensive brain scan, a risky spinal tap or in most cases a behavioural assessment by a doctor based on symptoms.

But US scientists at the Duke Eye Centre in North Carolina, wondered if changes might also be visible in the retina, which is an extension of the brain and so could offer a window into what is happening behind the skull.

FDA Approves New Fast-Acting Ketamine-Derived Antidepressant Spray

Posted by in categories: biotech/medical, neuroscience

A nasal spray that could alleviate symptoms of depression in just a few hours has been approved by the US Food and Drug Administration (FDA) – though the decision has attracted its share of criticism and controversy. The new drug, called esketamine, is a molecular variation of ketamine, which is already being used as an anesthetic, an antidepressant, and a party drug.

Esketamine will be sold as a spray called Spravato and is intended for patients with treatment-resistant depression, meaning they have failed to respond to at least two other types of antidepressant. Because of ketamine’s mind-altering effects and high potential for abuse, patients will be required to take Esketamine in a doctor’s office or clinic and remain under medical supervision for two hours after administration.

Most people with a diagnosis of depression are prescribed selective serotonin reuptake inhibitors (SSRIs) such as Prozac. These ensure that neurons have access to an increased amount of the neurotransmitter serotonin, which is a key emotional regulator. However, it is thought that around one-third of people with major depressive disorder (MDD) do not respond to conventional medications for the condition, which is why researchers are hunting for alternative treatments.
