Bee honey could be the unlikely key to unlocking the next era of computing

Neuromorphic computing that mimics the human brain is one step closer to reality as researchers from Washington State University have built a crucial circuit for this new type of computing using an unlikely pure substance.

Using bee-sourced honey, the researchers have built a proof-of-concept memory resistor or memristor. To accomplish this feat, they first turned the honey into a solid form and then held it between two metal electrodes in a similar way to how the brain’s synapses lay between pairs of neurons.

Following its creation, Washington State University researchers tested the device’s ability to quickly switch on and off at speeds ranging between 100 and 500 nanoseconds. The tests were successful and the researchers hope that their new memristor can help pave the way for biodegradable, sustainable and organic-based computing systems going forward.

In a press release announcing the discovery, associate professor of WSU’s School of Engineering and Computer Science, Feng Zhao provided further insight on honey’s potential in the creation of brain-like computer chips, saying:

“This is a very small device with a simple structure, but it has very similar functionalities to a human neuron. This means if we can integrate millions or billions of these honey memristors together, then they can be made into a neuromorphic system that functions much like a human brain.”

Neuromorphic computing

Conventional computer systems like those found in business computers and mobile workstations are based on the von Neumann architecture which involves an input such as a keyboard and mouse as well as an output like a monitor along with a CPU and RAM.

Link: The start of this link looks broken.echanisms from input to processing to memory to output takes a lot more power when compared to the human brain. For instance Fujitsu’s Fugaku supercomputer uses 28 million watts in order to run while the human brain uses only around 10 to 20 watts. This is why companies like Intel and IBM are working on neuromorphic chips that mimic how the human brain functions.

The human brain has over 100bn neurons with more than 1,000tn synapses or connections among them. As each neuron can both process and store data, the brain is much more efficient than a traditional computer.

At the same time, conventional computer chips are built using nonrenewable and toxic materials while neuromorphic chips, like the one created by researchers at Washington State University, can be made using biodegradable materials instead.

Going forward, Zhao’s team aims to shrink the size of its honey memristors from a microscale that is about the size of a human hair to a nanoscale which is about 1/1000 of a human hair. By doing so, the researchers will be able to bundle millions or even billions of honey memristors together to make a full neuromorphic computing system.

Revealed: iOS 18 Will Be Compatible With These iPhone Models

iOS 18 will be compatible with the same iPhone models as iOS 17, according to a post on X today from a private account with a proven track record of sharing build numbers for upcoming iOS updates. iOS 18 will be compatible with the iPhone XR, and hence also the iPhone XS and iPhone XS Max models with the same A12 Bionic chip, but older iPhone models will miss out. Here is the full compatibility list for iOS 18: iPhone 15 iPhone 15 Plus iPhone 15 Pro iPhone 15 Pro Max iPhone 14 iPhone 14 Plus iPhone 14 Pro iPhone 14 Pro Max iPhone 13 iPhone 13 mini iPhone 13 Pro iPhone 13 Pro Max iPhone 12 iPhone 12 mini iPhone 12 Pro iPhone 12 Pro Max iPhone 11 iPhone 11 Pro iPhone 11 Pro Max iPhone XS iPhone XS Max iPhone XR iPhone SE (2nd generation) iPhone SE (3rd generation) Apple is expected to announce iOS 18 at its Worldwide Developers Conference, which begins June 10, and the update should be released to all users with a compatible iPhone in

U.S. Government Sues Adobe for Hidden Termination Fees When Canceling Subscription

The United States Department of Justice and the Federal Trade Commission today levied a lawsuit against Adobe [ PDF ] for imposing a hidden termination fee on subscribers who want to cancel their Adobe plans. Adobe is accused of forcing subscribers to "navigate a complex and challenging cancellation process designed to deter them from cancelling subscriptions they no longer wanted." Adobe offers its Creative Cloud products on a subscription basis, with fees that are paid monthly. A monthly payment suggests that it's possible to cancel anytime, but that's not how Adobe works because most customers are actually locked into a hidden annual agreement. Customers who sign up for a free trial and are then charged and signed up to the default Creative Cloud plan, which is actually an annual contract. Canceling the annual contract requires customers to pay a lump sum of 50 percent of the "remaining contractual obligation" to cancel, despite the fact that servic

iOS 18 Introduces More Charging Limit Options on iPhone 15 Models: 85%, 90%, and 95%

All four iPhone 15 models feature a setting that prevents the devices from charging beyond 80% while toggled on, which can potentially improve an iPhone battery's lifespan by reducing the time that the battery is fully charged. And with iOS 18, Apple has taken this feature a step further by adding new 85%, 90%, and 95% charging limit options. Screenshot: Aaron Perris The feature can be found in the Settings app under Battery → Charging. The charging limit feature remains exclusive to the iPhone 15 lineup on the first iOS 18 beta, with the option not found on the iPhone 14 Pro or older. The first iOS 18 beta is now available for Apple Developer Program members, and a public beta will follow in July. Following beta testing, the update should be widely released to all users with an iPhone XS or newer in September.
