Orthostatic hypotension is the technical term for a temporary drop in blood pressure when a person stands up after sitting or lying down because blood rushes to the feet, away from the brain. Dizziness or fainting due to changes in blood flow can occur after lengthy bed rest, among people with certain health disorders or, in the case of astronauts, being in a low-gravity environment.
Why? In the case of lung cancer, it may be because over half of lung cancers are caused by smoking and even more are statistically linked to smokers (second-hand smoke) but it still carries a stigma. Liver cancer may be associated with alcoholics. Both of those are lifestyle diseases and not genetic bad luck.
Weather Channel Meteorologists Jim Cantore & Tevin Wooten Go Immersive Mixed Reality To Highlight Apollo 11
You may have seen it in the past, during coverage of a flood, when they had everything from televisions to fish floating as their pundits exaggerated the effects of water rising. While the hyperbolic claims they made were ridiculous, they were no more ridiculous than what other media outlets did to grab viewers, and the technology was outstanding.
To adults it is recognized as somewhat ridiculous but at least there is the pretense of mature consent, that it is only being shared with trusted romantic partners, while with teens there is concern these images will find their way into the hands of others and follow them throughout their early lives at a time when everything is already dramatic.
A new video, created at Arizona State University's School of Earth and Space Exploration, shows what Armstrong saw out his window as the lander descended — and that means we can see for yourself why he took control. They used the crew's voice recording, the timings, a video taken on film and images taken from lunar orbit by the LROC over the last 10 years.
Optogenetics biotechnology, using light to manipulate neurons so that they can be turned on or off, has led to a device that replicates the way the brain stores and loses information.
The new chip is based on an ultra-thin material that changes electrical resistance in response to different wavelengths of light, enabling it to mimic the way that neurons work to store and delete information in the brain.
New Efforts by the FDA and coastal cities to kill off e-cigarettes with bans and restrictions will drive existing users to smoke more cigarettes, according to new research from Duke Health.
The findings, from a survey of 240 young U.S. adults who use both e-cigarettes and traditional tobacco cigarettes, are scheduled to be published July 15 in the journal Substance Use & Misuse.
"The FDA now has regulatory authority over all tobacco products, including e-cigarettes and we know that some communities have taken action to ban flavored e-cigarette products," said Lauren Pacek, Ph.D., the study's lead author and an assistant professor in psychiatry and behavioral sciences at Duke.
While some in media will use that to sound this week's 'science is killing us' alarm, the reality is that something that is not a concern is being linked to something else not a concern.
The specimen was found by and named after Chris Haefner, and is set to be "unveiled" this September at a conference in Moscow, Russia.

Why 500,000 Naruto Runners Can't Storm Area 31 By Running With Hands Trailing 'faster Than A Bullet' Across 26 Miles Of Desert
This is an internet joke event. Lots of people saying they will go just for the fun of it. Doesn't mean they will turn up, out of those 500,000 or more, it would be a surprise if 50 actually turn up.. Very very silly and not a serious threat to the base. These people are just going to run towards it in a crowd if anyone turns up, over 26 miles of hot desert and rough terrain with their arms behind their backs.
This is what they plan to do, a Naruto run (the bit at the end of this video about anime being illegal is a joke).
No Asteroid Warning For 2007 FT3 - And What NASA'S Sentry Table Really Says In Words - For Those Scared By Fake Asteroid News
This may help with this and other fake asteroid news. First, it can't change its direction (or only minutely e.g. due to pressure of its emitted heat radiation as it spins).
What happens is that they don't know its orbit well. There is a very remote chance it could hit, but they would know well before and warn everyone affected. They remove dozens of “No Hazard” asteroids like this from the table every year. Since 2002, they have already removed well over 2000 of them and there is no reason at all for the public to get scared of this one.
They have already removed 83 “No hazard” objects from the table for 2019, with 25 left to remove.
For instance in the last four years the numbers removed are:
What Will My City Be Like In 2050? E.g. London Like Barcelona (at 2°C) - Easier To Understand With Climates Someone Already Has
This is being reported in a way that scares some people But this is not new climate research, and changes nothing about the 2018 IPCC report. It is just a public education paper, helping people to understand the consequences of climate change, and evaluate environmental policies. It could have been written any time in the last decade and would have been essentially the same with minor tweaks.
