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.

Sabine Hossenfelder: Backreaction: Dark matter nightmare: What if we are just using the wrong equations?
#science #cosmology #gravityhttp://backreaction.blogspot.com/2019/10/dark-matter-nightmare-what-if-we-just.html
- 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.*

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.http://www.asahi.com/ajw/articles/AJ201909290001.html
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.

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.#science #medicine #health #aspirin #pollution #COPD
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.

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.China’s tree-planting drive could falter in a warming world

Dangerous liaisons as tumour cells form synapses with neurons
Why brain tumours progress rapidly is unclear. The finding that such cancer cells form synaptic connections with neurons uncovers an interaction that accelerates tumour growth rate and lethality.

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.https://www.houstonchronicle.com/local/space/mission-moon/article/Blazing-a-trail-First-woman-at-Mission-Control-14055864.php
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.
