Researchers create virtual smells by electrocuting your nose – TechCrunch

Published

on

The IEEE has showcased one of the coolest research projects I’ve seen this month: virtual smells. By stimulating your olfactory nerve with a system that looks like one of those old-fashioned kids electronics kits, they’ve been able to simulate smells.

The project is pretty gross. To simulate a smell, the researchers are sticking leads far up into the nose and connecting them directly to the nerves. Senior research fellow at the Imagineering Institute in Malaysia, Kasun Karunanayaka, wanted to create a “multisensory Internet” with his Ph.D. student, Adrian Cheok. Cheok is Internet famous for sending electronic hugs to chickens and creating the first digital kisses.

The researchers brought in dozens of subjects and stuck long tubes up their noses in an effort to stimulate the olfactory bulb. By changing the intensity and frequency of the signals, they got some interesting results.

The subjects most often perceived odors they described as fragrant or chemical. Some people also reported smells that they described as fruity, sweet, toasted minty, or woody.

The biggest question, however, is whether he can find a way to produce these ghostly aromas without sticking a tube up people’s noses. The experiments were very uncomfortable for most of the volunteers, Karunanayaka admits: “A lot of people wanted to participate, but after one trial they left, because they couldn’t bear it.”

While I doubt we’ll all be wearing smell-o-vision tubes up our noses any time soon, this idea is fascinating. It could, for example, help people with paralyzed senses smell again, a proposition that definitely doesn’t stink.

Hubble Snaps Stunning Pictures Of Colliding Galaxies

Published

In its latest exploratory hunt covering the Arp-Madore territory, the Hubble telescope found something remarkable in the Arp-Madore 417-391 collision event. What is truly noteworthy is the intensity of the galactic interaction and the strong gravitational forces at play here. The pair of galaxies have contorted each other, a forming a ring-like structure, while their cores sit side by side. Personally, I think the cosmic duo looks more like a pair of wireless over-the-ear headphones like Sony’s acclaimed WH-1000 XM4 cans.

The formation of ring-like structures at a galactic scale, especially in the events of merger between two galaxies, is quite rare. According to estimates, there are only a few hundred documented in Earth’s cosmic neighborhood. A ring formation at such a massive scale is nothing short of a chance event, because the interacting galaxies have to collide at just the right angle and orientation to form such a structure (via LiveScience).

The ring’s outline is usually made up of young blue stars, serving somewhat like an elongated genesis chamber of stars. However, rings generated from galactic collisions are rather short-lived (on a cosmic time scale, that is), and usually lose their distinct structure a few hundred million years.

Today’s Wordle Answer #526 – November 27, 2022 Solution And Hints

Published

on

The solution to today’s Wordle puzzle ( #526 – November 27, 2022) is “happy.” Its most popular meaning is to be glad or pleased, but the root word “hap” means chance or fortune, and that’s why the word “happy” is also used to mean lucky, fortunate or providential circumstances or unforeseen success (via Merriam-Webster).

We solved the puzzle in four tries today — the first two guesses, ounce and plait, were an attempt to eliminate all the vowels early on, which is our preferred Wordle-solving strategy. Those two whittled down the possible answers from 383 to just eight, and the third guess, debug, reduced that further to three. The word happy was our lucky fourth guess, and what made us even happier is that it took WordleBot the same number of tries to solve the puzzle. We hope you do it even faster, and if you’re looking for more puzzles to try your hand at, check out these other games like Wordle.

Orion Capsule Breaks Record Of Farthest Spacecraft Traveled From Earth

Published

on

“It just so happened that with that really large orbit, high altitude above the moon, we were able to pass the Apollo 13 record,” Jim Geffre, Orion vehicle integration manager at NASA, said of the Orion’s record-breaking journey. On Monday, Nov. 28, Orion will reach a peak distance of 268,553 miles before the orbital manoeuvring system engine kicks in and propels it toward another close flyby with the Moon in the first week of December. Six days later, the vehicle is expected to return home.

According to NASA, the Orion is “built to take humans farther than they’ve ever gone before.” The Orion capsule has been co-engineered with Lockheed Martin, and it is touted to be the only vehicle capable of manned deep space mission and returning back to Earth at high speed from targets such as the Moon and beyond. With the Artemis project, NASA is actually aiming for the first crewed visit to the Mars, as well.

Capable of carrying four crew members, the capsule employs a total of 355,056 parts and can support missions lasting up to 21 days in its current state (via NASA). The capsule has systems for monitoring and maintaining aspects like humidity, carbon dioxide, oxygen, and radiation shielding, among other vital elements. Interestingly, the Orion’s base also features the world’s largest ablative heat shield that measures 16.5-feet in diameter and will protect the vehicle when it makes high-speed entry into Earth’s atmosphere.
