Common Plastic Additive Linked to Autism And ADHD, Scientists Discover

The number of kids being diagnosed with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) has risen sharply in recent decades, and a new study points to the common plastic additive bisphenol A (BPA) as a potential reason why.

BPA is used in a lot of plastics and plastic production processes, and can also be found inside food and drink cans. However, previous research has also linked it to health issues involving hormone disruption, including breast cancer and infertility.

In this new study, researchers from Rowan University and Rutgers University in the US looked at three groups of children: 66 with autism, 46 with ADHD, and 37 neurotypical kids. In particular, they analyzed the process of glucuronidation, a chemical process the body uses to clear out toxins within the blood through urine.

Researchers develop 3D printing method that shows promise for repairing brain injuries

A breakthrough technique developed by University of Oxford researchers could one day provide tailored repairs for those who suffer brain injuries. The researchers have demonstrated for the first time that neural cells can be 3D-printed to mimic the architecture of the cerebral cortex. The results have been published in the journal Nature Communications.

Brain injuries, including those caused by trauma, stroke, and surgery for tumors, typically result in significant damage to the cerebral cortex (the outer layer of the human brain), leading to difficulties in cognition, movement and communication. For example, each year, around 70 million people globally suffer from traumatic brain injury (TBI), with 5 million of these cases being severe or fatal. Currently, there are no effective treatments for severe brain injuries, leading to serious impacts on quality of life.

Tissue regenerative therapies, especially those in which patients are given implants derived from their own , could be a promising route to treat brain injuries in the future. Up to now, however, there has been no method to ensure that implanted stem cells mimic the architecture of the brain.

Gboard CAPS: the cool new way to type without your fingers

“As I was racking my brains for a way to make keyboards more portable and fashionable, I had an aha moment. Carrying around a keyboard was a closed-minded idea.”

In yet another episode of “Cool stuff the Japanese come up with”, Google Japan has once again taken a playful detour from the mundane with its latest creation: the Gboard CAPS.

While this head-mounted keyboard integrated into a baseball hat may sound like the stuff of sci-fi or the whimsical fantasies of keyboard enthusiasts, the Gboard CAPS project is real, and designed with a delightful touch of humor.

How smell affects the colors we see

It turns out there is a correlation between odors and colors that is quite commonplace.

An example of synesthesia, a perceptual phenomena when activation of one sensory or cognitive pathway results in involuntary experiences in another, is the idea of “smell color” or connecting odors with colors. In this situation, those who experience “smell-color synesthesia,” a particular form of synesthesia, may think that odors have corresponding colors.
