Praying mantises are one of the only invertebrates that can see in 3D. Neuroscientist Jenny Read is using tiny 3D glasses to test their depth perception, while Ronny Rosner uncovers the nerve cells responsible for this so-called stereoscopic vision.

Wow! I've often asked myself why aerospikes didn't take off. There are obvious challenges but the advantage seemed to be worth exploring. This article is the most thorough exploration of that that I've seen. H/T #space #rockets #science
Are Aerospike Engines Better Than Traditional Rocket Engines?

Sabine Hossenfelder: Backreaction: Dark matter nightmare: What if we are just using the wrong equations?


#science #cosmology #gravity
  • Needless to say, taking an average on one side of the equation requires that you also take an average on the other side. But since the gravitational part is non-linear, this will not give you the same equations that we use for the solar system: The average of a function of a variable is not the same as the function of the average of the variable. We know it’s not. But whenever we use general relativity on large scales, we assume that this is the case.*

2019 Earth Science Week photo competition winners | The Guardian

The Geological Society has announced the winners of this year’s competition, which for the first time allowed in images taken from around the world. According to the society, the photographs showcase the rich diversity of environments in which scientists, live, work and travel.
The images will appear in the society’s 2020 calendar and will also feature in a free exhibition at its London HQ to mark Earth Science Week

Artificial blood developed for patients of any blood type:The Asahi Shimbun

Japanese researchers said they have developed artificial blood that can be transfused into patients regardless of their blood type and can vastly improve the chances for survival of seriously injured people.

The artificial blood created by a team of scientists primarily from the National Defense Medical College has proved effective in experiments on rabbits.

For possible applications on humans, the artificial blood gets around problems with identifying blood types in emergency situations and overcomes limits on storing real blood from donors.

Researchers Developed a Lens that's 1000x Thinner than Regular Optics | PetaPixel

A team of researchers from the University of Utah have made a major breakthrough in optics by developing a new kind of flat lens that’s only ten microns thick, making it “a thousand times thinner than regular lenses.” And apparently, it doesn’t sacrifice performance.

Aspirin, Strangely Enough, Might Protect Our Lungs From Air Pollution | Gizmodo

A dose of aspirin can do more than just soothe your headache, a new study suggests—it might also protect your lungs from air pollution.

Air pollution harms our bodies in all sorts of ways, both short-term and long-term. One of these ways is through irritating and inflaming lung cells. So it makes sense that aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) could have a protective effect. There’s even research showing that the daily use of aspirin is linked to a reduced risk and slower progression of chronic obstructive pulmonary disease (COPD), a lung condition characterized by chronic inflammation which can be caused or worsened by air pollutants like tobacco smoke.

Two-dimensional semiconductors host high-temperature exotic state
The phenomenon of Bose-Einstein condensation is typically limited to extremely low temperatures. The effect has now been spotted at much higher temperatures for particles called excitons in atomically thin semiconductors.

What a black hole looks like up close, according to NASA

"This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole where infalling matter has collected into a thin, hot structure called an accretion disk. The black hole’s extreme gravity skews light emitted by different regions of the disk, producing the misshapen appearance."

This 1988 #Shell #report, discovered by Jelmer Mommers of De Correspondent, shines light on what the company knew about #climate #science, its own role in driving global #CO2 emissions, the range of potential political and social responses to a warming world.

The confidential report, “The #Greenhouse Effect,” was authored by members of Shell’s #GreenhouseEffect Working Group and based on a 1986 study, though the document reveals Shell was commissioning “greenhouse effect” reports as early as 1981. Report highlights include:

* A thorough review of climate science literature, including acknowledgement of fossil fuels’ dominant role in driving greenhouse gas emissions. More importantly, Shell quantifies its own products’ contribution to global CO2 emissions.
* A detailed analysis of potential climate impacts, including rising sea levels, ocean acidification, and human migration.
* A discussion of the potential impacts to the #fossilfuel sector itself, including legislation, changing public sentiment, and infrastructure vulnerabilities. Shell concludes that active engagement from the energy sector is desirable.
* A cautious response to uncertainty in scientific models, pressing for sincere consideration of solutions even in the face of existing debates.
* A warning to take policy action early, even before major changes are observed to the climate.

Researchers warn that the country’s push to hold back its deserts could strain water resources.
China has planted billions of trees over the past four decades as part of its fight against expanding deserts, mostly in its north. Each year, the country sows seedlings over an area nearly the size of Ireland. It is even sharing its desert-control methods with others as part of its massive Belt and Road trade initiative.

Low grade "journalists" and internet mob attack RMS with lies. In-depth review.

Low grade "journalism" is making another victim. Philosopher and activist Richard Matthew Stallman is having his ideas distorted and his writings taken out of context just so a "journalist" can get re-tweets from people that didn't even read their article.
Now to what actually happened. In chronological order. (Not as long as it seems. Most of it are quotations from original sources because I'm not an incompetent "journalist".)

Read it!

Chelsea Wegner was shocked when she landed in Anchorage, Alaska, in July, on her way to a research cruise in the Bering Sea. Smoke from wildfires across the state had darkened the skies, and Anchorage was in the midst of a heatwave that saw temperatures soar past 32 °C for the first time in recorded history.

Frances "Poppy" Northcutt was the first female engineer in NASA's mission control.
Poppy Northcutt’s headset crackled as a fellow mission controller again directed his colleagues to turn to a specific camera channel on their consoles.

It was 1968 and the 25-year-old Northcutt often was too busy running Apollo 8 simulations to pay this channel any heed. But on this particular day, she wasn’t quite so busy.

What she saw made her breath catch in her throat. Her male colleagues had trained a Mission Control room camera directly on her. And they had been watching it for months.

Northcutt didn’t tell anyone about the camera — or how it made her feel. As the first and only woman working in Mission Control at NASA’s Johnson Space Center in Houston, she knew the treatment could be a lot worse.
