Insects are a sustainable source of protein. Now, scientists show that many insects are as good a source of iron as sirloin beef.
| Quote: | Not only is entomophagy widespread, it is also probably healthier for people and the planet than eating other animals. Compared to raising cows and chickens, insect farming requires less resources and suffers from fewer ethical considerations. Insects are also incredibly nutritious. For instance, house crickets are rich in protein, but contain only about one-third of the fat found in beef. And, as new research indicates, insects can also be a good source of iron.
In food, iron comes in two varieties: Heme iron and non-heme iron. Heme iron (which is found in hemoglobin, the molecule in red blood cells that carries oxygen) is "bioavailable," meaning that it is easily absorbed and utilized by the body. Foods containing heme iron are good dietary sources of iron. On the other hand, iron that is not found in heme cannot be easily used by the body. Therefore, any study that analyzes the bioavailability of iron in food must take this into account.

As shown, buffalo worms have more bioavailable iron than beef. The iron bioavailability in grasshoppers and mealworms was comparable to but slightly less than beef, while crickets were not a particularly good source of dietary iron. |

As the global climate warms up to 77° F, soil respiration rates increase, adding even more carbon dioxide to the atmosphere and accelerating climate change
| Quote: | | One of the greatest challenges in projecting future shifts in the global climate is understanding how soil respiration rates will change with warming. Multiple experimental warming studies have explored this response, but no consensus has been reached. Based on a global synthesis of 27 experimental warming studies spanning nine biomes, we find that although warming increases soil respiration rates, there is limited evidence for a shifting respiration response with experimental warming. We also note a universal decline in the temperature sensitivity of respiration at soil temperatures >25 °C. Together, our data indicate that future respiration rates are likely to follow the current temperature response function, but higher latitudes will be more responsive to warmer temperatures. |

New study shows LED lights attract fewer insects than other lights
| Quote: | The study, funded by the Natural Environment Research Council and UK lighting manufacturer Integral LED, used customised traps at 18 field test sites across south-west England, illuminated by a series of LED, filament and fluorescent light sources. Over 4,000 insects were carefully identified. The results showed that LEDs attracted four times fewer insects compared with the traditional incandescent lamps, and half as many as were attracted to a compact fluorescent lamp.
Notably, for biting flies (midges in the genus Culicoides, some species of which are vectors of wildlife disease), 80 percent were attracted to the filament lamp, 15 percent to the compact fluorescent and only 2-3 percent to each of the two different LED lamps. |
May have applications to help prevent diseases caused by heat-seeking insects such as mosquitos. |

Next time you guys visit KTown, I suggest you stop by a market and try some of these...
Oh, and it helps if you wash it down with some beer.

Brain Implant Eases Communication by Late-Stage A.L.S. Patient
| Quote: | The patient, Hanneke De Bruijne, a doctor of internal medicine from the Netherlands, received a diagnosis of amyotrophic lateral sclerosis, also known as A.L.S. or Lou Gehrig’s disease, in 2008. The neurons controlling her voluntary muscles were dying, and eventually she developed a condition called locked-in syndrome. In this state, she is cognitively aware, but nearly all of her voluntary muscles, except for her eyes, are paralyzed, and she has lost the ability to speak.
In 2015, a group of researchers offered an option to help her communicate. Their idea was to surgically implant a brain-computer interface, a system that picks up electrical signals in her brain and relays them to software she can use to type out words.
“It’s like a remote control in the brain,” said Nick Ramsey, a professor of cognitive neuroscience at the University Medical Center Utrecht in the Netherlands and one of the researchers leading the study. On Saturday, the research team reported in The New England Journal of Medicine that Ms. De Bruijne independently controlled the computer typing program seven months after surgery. Using the system, she is able to spell two or three words a minute.
“This is the world’s first totally implanted brain-computer interface system that someone has used in her daily life with some success,” said Dr. Jonathan R. Wolpaw, the director of the National Center for Adaptive Neurotechnologies in Albany. |

Why would eating insects instead of cattle create ethical considerations? All are raised for one objective, to be food. I see no difference.

Had the same thought. Maybe their size, being mammals and all the similarities there, being occasional pets, visible emotions (same thing as size I guess basically), and number relative to insects is what they mean.
Go science thread! Let's get some Mars and med news going. Here's my part:

Fruit news: Fijian ants began cultivating fruit millions of years ago, gathering seeds, then seeking out fissures in tree bark to plant them in before fertilizing them with their feces.
| Quote: | It lives in Fiji and has been farming plants for some 3 million years.
The ant in question is Philidris nagasau, an ordinary looking, small, black ant. It lives in and eats Squamellaria, a plant that grows in the cracks and elbows of different kinds of trees. The Squamellaria plant, which looks more like a fungus, forms lumpy, brown, bulbous protrusions from the branches of the trees it lives on.
The new study, published in Nature Plants, shows that these ants not only live inside these hollow plants, they also farm them.
I first noticed the relationship when I saw dozens of these ant-filled plants clustered in the same trees, says Guillaume Chomicki, a botanist at the Ludwig-Maximilians-University of Munich and the lead author on the study. He saw ants from a single colony moving back and forth between the plants they lived in.
He found that the ants gather Squamellaria seeds and leave them in the cracks of trees. As the plants grow, the ants fertilize them with their own poop. Once the plants produce fruits, the ants harvest the seeds, and the process starts all over again.
Every plant Chomicki checked had ants living in it. And the ants don't hang out in other plants, suggesting that the ants and plants are dependent on one another. The ants seem to work with and live in six different species of this plant. |
Ants invented agriculture. Thanks ants.

Mars News: An enormous underground ice deposit on Mars contains as much water as Lake Superior
| Quote: | Water ice makes up half or more of an underground layer in a large region of Mars about halfway from the equator to the north pole.
The amount of water in this deposit is about as much as in Lake Superior. It was assessed using a radar aboard a NASA spacecraft orbiting Mars.
This research advances understanding about Mars' history and identifies a possible resource for future astronauts. |

Dunno about ethics, but cattle are a huge environmental strain, releasing tons of methane and requiring large swaths of land and insane amounts of water to raise. Insects would likely be a far more sustainable way of receiving protein (and I guess iron).
Edit - and I see the article blurb mentioned exactly that. Bah, that's what I get for only reading the headline and not bothering with even the short blurb in the post. |

Dino News:'Once in a lifetime find': Dinosaur tail discovered trapped in amber
| Quote: | The tail of a 99-million year old dinosaur has been found entombed in amber, an unprecedented discovery that has blown away scientists.
Xing Lida, a Chinese paleontologist found the specimen, the size of a dried apricot, at an amber market in northern Myanmar near the Chinese border. |

'Star in a Jar' Fusion Reactor Works and Promises Infinite Energy
| Quote: | It works like this: Unlike a traditional fission reactor, which splits atoms of heavy elements to generate energy, a fusion reactor works by fusing the nuclei of lighter atoms into heavier atoms. The process releases massive amounts of energy and produces no radioactive waste. The "fuel" used in a fusion reactor is simple hydrogen, which can be extracted from water.
However, to achieve fusion, scientists must generate enormously high temperatures to heat the hydrogen into a plasma state. The plasma is so hot, in fact, that it would instantly burn material used to contain it. That's where the stellerator design comes in. The W7-X device confines the plasma within magnetic fields generated by superconducting coils cooled down to near absolute zero. The plasma — at temperatures upwards of 80 million degrees Celsius — never comes into contact with the walls of the containment chamber. Neat trick, that. |

Not quite but it's a step in the right direction for sure. I wonder whether we'll achieve practical fusion energy in my lifetime
