Combining self-assembly techniques from across scientific disciplines could allow us to precisely build any material structure.

Nanocars are an impressive achievement – but nanoarchitectonics can unlock a far greater range of material structures.

In a lecture at the American Physical Society in 1959 titled ‘There’s Plenty of Room at the Bottom’, Richard Feynman argued that huge possibilities come from working in the world of molecules and atoms. He dreamed of ultra-small computers, cars running under a microscope, and medical machines working in our body.

These dreams are now coming true. In 2017, we had the first World Nanocar Race in Toulouse, France. Six teams from around the world manipulated nanometre-size cars to run on a metal surface under a scanning tunnelling microscope. A nanocar is 2 billion times smaller than a usual car, corresponding to the size difference between a rice grain and the Earth. Feynman only imagined cars 4000 times smaller than normal. However, few of the nanocars resembled cars, and none were powered by their own motors. There’s still plenty of room for improvement.

Einstein, who was not involved in the study, noted that the number of LEEP procedures performed per year in the U.S. — approximately 500000 — indicates the scope of the disease. Additionally, he pointed out that due to the association between LEEP and preterm births, “it is truly important to explore these nonsurgical agents.”

Imiquimod directly activates innate immune cells through Toll-like receptors 7 and 8, resulting in production of cytokines and interferons.

Fonseca and colleagues evaluated the histologic response of cervical HSIL — defined as regression to cervical intraepithelial neoplasia (CIN) 1 — after topical application of 5% imiquimod cream.

Today we discuss Mars surface conditions with the villain from a 90s Kid’s movie. I also get mad (but not in a technical way). Apologies for this one.

The next one will be on Space Guns and Jules Verne which is more fitting for the channel.

Transition footage and thumbnail image are from the Jet Propulsion Laboratory. Perseverance and Ingenuity are nifty.

Last month, the United States Air Force successfully test flew an unmanned aerial vehicle (UAV) called Skyborg, operating on an autonomous hardware/software suite, for the very first time.

The military aims for this UAV to fuel collaboration among manned and . For its first test run, the Skyborg suite flew aboard a Kratos UTAP-22 Mako air vehicle in the first step of what’s known as the Autonomous Attritable Aircraft Experimentation Campaign.

By and large, the US Air Force Research Laboratory seeks a UAV solution that can carry out all of the functions of a manned aerial vehicle but also with the option of manned operation.

Wines and table grapes exist thanks to a genetic exchange so rare that it’s only happened twice in nature in the last 6 million years. And since the domestication of the grapevine 8000 years ago, breeding has continued to be a gamble.

When today’s growers cultivate new varieties – trying to produce better-tasting and more disease-resistant grapes – it takes two to four years for breeders to learn whether they have the genetic ingredients for the perfect flower.

Females set fruit, but produce sterile pollen. Males have stamens for pollen, but lack fruit. The perfect flower, however, carries both sex genes and can self-pollinate. These hermaphroditic varieties generally yield bigger and better-tasting berry clusters, and they’re the ones researchers use for additional cross-breeding.

Scientists at UC Santa Cruz led a team of researchers from 30 institutions across North America in analyzing data from 3212 camera traps to show how human disturbance could be shifting the makeup of mammal communities.

The new study, published in the journal Global Change Biology, builds upon the team’s prior work observing how wildlife in the Santa Cruz Mountains respond to human disturbance. Local observations, for example, have shown that species like pumas and bobcats are less likely to be active in areas where humans are present, while deer and wood rats become bolder and more active. But it’s difficult to generalize findings like these across larger because human-wildlife interactions are often regionally unique.

So, to get a continent-wide sense for which species of mammals might be best equipped to live alongside humans, the team combined their local camera trap data with that of researchers throughout the U.S., Canada, and Mexico. This allowed them to track 24 species across 61 regionally diverse camera trap projects to see which larger trends emerged.
