Noise Cancellation for the Brain

Yeah, you read that right. This research explored a novel approach to helping people with trouble falling asleep at night. It developed a device that delivers precisely timed sound pulses to help users fall asleep faster. The technology monitors brain waves (EEG), specifically targeting alpha waves associated with wakefulness when a person's eyes are closed. The researchers obtained promising results, with the device significantly reducing the time it takes to fall asleep. The product is out now for $349.

As humanity’s data production and need for storage increases, the demand for more efficient storage methods increases. Additionally, magnetic tape, the current most employed method, is near its physical limits, further increasing the need for innovation. One solution can be found in DNA, which can store information much more efficiently than current methods and does not have the same cooling demands as magnetic tape. Think of DNA as being in base four while current storage is binary. This article suggests that you could store the entire internet –all 120 zettabytes– on a volume of DNA the size of a sugar cube. While there are many limitations, and we are not quite ready to make the DNA Drive a widespread reality, the technology is quite promising. Just as current storage methods led to a boom in information, DNA might do the same. Who knows what advancements in technology will lead to…
