Scientists Freeze Atoms to Near Absolute Zero
Posted by Quinn Sena in categories: food, particle physics, quantum physics
:oo.
We usually think of microwaves as waves that heat things up, usually leftover food, but did you know that they can also cool things down? For example, physicists recently decided to use them to freeze atoms, and attempts have been very successful: They managed to cool them down to within a millionth of a degree of absolute zero (–273.15°C or −459.67°F).
The University of Sussex team, led by Winifried Hensinger, had their results published in Physical Review Letters.

Environmentalists are Wrong: Nature Isn’t Sacred and We Should Replace It
Posted by Zoltan Istvan in categories: biotech/medical, ethics, food, information science, life extension, robotics/AI, space, sustainability, transhumanism
Environmentalism and climate change are increasingly being pushed on us everywhere, and I wanted to write the transhumanism and life extension counter argument on why I prefer new technology over nature and sustainability. Here’s my new article:
On a warming planet bearing scars of significant environmental destruction, you’d think one of the 21st Century’s most notable emerging social groups—transhumanists—would be concerned. Many are not. Transhumanists first and foremost want to live indefinitely, and they are outraged at the fact their bodies age and are destined to die. They blame their biological nature, and dream of a day when DNA is replaced with silicon and data.
Their enmity of biology goes further than just their bodies. They see Mother Earth as a hostile space where every living creature—be it a tree, insect, mammal, or virus—is out for itself. Everything is part of the food chain, and subject to natural law: consumption by violent murder in the preponderance of cases. Life is vicious. It makes me think of pet dogs and cats, and how it’s reported they sometimes start eating their owner after they’ve died.

A mysterious E. coli outbreak has infected 72 people and counting
Posted by Quinn Sena in categories: biotech/medical, food
This post has been updated.
We’ve all just barely forgotten about the great American lettuce contamination of 2018, in which we were forced to forgo romaine over Thanksgiving, and another E. coli outbreak has already hit. The Centers for Disease Control released a notice of an ongoing outbreak centralized around Kentucky earlier this month, but at the time they weren’t sure what foods were to blame for the 72 illnesses and eight hospitalizations. Nearly half of those infections were in Kentucky, with the rest in Tennessee, Georgia, Ohio, and Virginia.
On April 12 the CDC posted an update: 109 people have been sickened by E. coli so far (that the CDC is aware of), and cases have cropped up in a sixth state (Indiana). Seventeen people have gone to the hospital, but no deaths are reported at this time.

A Moss Can Naturally Clean Harmful Arsenic From Water
Posted by Quinn Sena in categories: biotech/medical, food, sustainability
If you happen to be thirsty in the woods, there are a lot of things you can stick in your canteen to help clean up your drinking water. There are chlorine pills and filters (not crystals — never crystals). And now scientists have identified a certain kind of moss that could do it, too.
The moss is called Warnstorfia fluitans. It grows in Swedish wetlands contaminated with the toxic arsenic from nearby mining operations. Researchers found that the moss brought the arsenic levels of water down to drinkable levels surprisingly quickly, according to research published in the journal Environmental Pollution.
In northern Sweden, iron mines have contaminated much of the water with arsenic, a metal that is also toxic to humans. That harmful combination works its way into agricultural products like rice, traveling throughout the food web.

Bacteria flip an electric switch to worsen food poisoning
Posted by Quinn Sena in category: food
;-;
Salmonella bacteria flip an electric switch as they hitch a ride inside immune cells, causing the cells to migrate out of the gut toward other parts of the body, according to a new study publishing on April 9 in the open-access journal PLOS Biology by Yaohui Sun and Alex Mogilner of New York University and colleagues. The discovery reveals a new mechanism underlying the toxicity of this common food-borne pathogen.
Salmonella are among the commonest, and deadliest, causes of food poisoning, causing over 400,000 deaths every year. Many of those deaths result when the bacteria escape the gut inside immune cells called macrophages. Macrophages are drawn to bacteria in the gut by a variety of signals, most prominently chemicals released from the site of infection. Once there, they engulf the bacteria as a regular part of their infection-fighting job. However, rather than remaining there, bacteria-laden macrophages often leave the site and enter the bloodstream, disseminating the bacteria and greatly increasing the gravity of the infection.
