Solar energy 'breakthrough' could replace fossil fuels in some industries
If solar energy is truly going to take over from fossil fuels, it needs to be hot enough for not only generating power, but replacing industrial processes outright -- and even the 1,049F of the best solar concentrator systems wouldn't cut it. Heliogen, however, may have finally cracked that barrier. The Bill Gates-backed startup has successfully concentrated solar energy at "breakthrough" temperatures above 1,832F, making it toasty enough to replace fossil fuels for industrial tasks like producing cement or steel.The trick is the use of computer vision (aka a form of AI) to align a large array of mirrors as they reflect sunlight on a solitary target.

Toxoplasma gondii is a tiny organism that lives inside cells. It might well live inside your cells – the parasite is thought to infect up to 50% of the world’s There was also no evidence that was linked to ‘poor impulse control ’, e.g. criminal convictions, driving offenses, and accident claims on insurance.
There's a fairly good chance you're infected with a mind-altering parasite. And if not you... then maybe your cat. The parasite, known as Toxoplasma gondii, is one of the most prolific proliferators on the planet, with an ability to infect basically any warm-blooded animal on Earth. Scientists think it may have infected upwards of 3 billion human hosts.
But it's okay! There's no real reason to flip out -- it's mostly harmless.
Toxoplasma is a remarkable single-celled organism in the same category as the malaria parasite and has. Studies have shown rodents infected with Toxoplasma are more fearless and some researchers have connected infection in .
National Board of Review Names 'The Irishman' the Year's Best Film
The National Board of Review has named Martin Scorsese's "The Irishman" the best film of 2019. Scorsese and two of the film's stars, Robert De Niro and Al Pacino, will also receive the organization's inaugural Icon Award.
Toxoplasma gondii is a tiny organism that lives inside cells. It might well live inside your cells – the Among other organs, the parasite infects the brain, and it has been blamed for making people more Sugden et al. examined the Dunedin Longitudinal Study , a sample of over 1,000 people born in New
Are you really in control of yourself? 33-50% of all human carry a mind altering parasite called Toxoplasma gondii.
In most warm-blooded mammals, the parasite is basically inert and forms protective cysts to survive, including in brain tissue. The cysts remain in the body for life, slumbering away within the host (unless they have a weakened immune system, in which case, toxoplasma can be bad news).
But in a cat's gut, it's a different story. That's where the parasite gets down to business. Toxoplasma's life goal is singular: Get inside a cat, mature and reproduce. Once the toxoplasma "children" are born, the cat excretes them -- and the cycle starts anew.
To get into the cat, the standing theory suggests Toxoplasma changes rodent behavior by using a form of "mind control". Instead of being repelled by cat odors or hiding away, the rodents are more likely to face a feline. It seems to decrease anxiety and make the rodents more courageous. That increases their chances of being eaten, giving Toxoplasma the best chance to sneak inside its preferred host. The rodents are furry Trojan horses, bursting with a battalion of parasites waiting to get inside a cat.
The FDA is fast-tracking an algorithm that screens for heart failure
Today, the FDA granted "breakthrough status" to an algorithm that could make screening for heart failure more accessible -- both in traditional clinics and telehealth settings. The algorithm uses a deep neural network developed by digital health company Eko and Mayo Clinic. With as little as 15 seconds of electrocardiogram (ECG) data, it can identify Left Ventricular Ejection Fraction (LVEF), a measure that's commonly used to diagnose patients with heart failure.The algorithm was introduced in a study published in Nature Medicine in January 2019. It was trained on 44,959 patients and tested on 52,870 patients. In those initial tests, it showed 87.
Mind Control by Parasites . Half of the world's human population is infected with Toxoplasma , parasites in the body—and the brain. Since cats don't want to eat dead, decaying prey, Toxoplasma takes the evolutionarily sound course of being a "good" parasite , leaving the rats perfectly healthy.
This weeks video looks at the protozoan parasite Toxoplasma Gondii. We look at how this organism uses the host such as the cat to reproduce in its gut
However,. Studies have shown the organism does affect behavior in mice, but how the parasite achieves this remains unknown. Is it an adaptive mechanism spurred by evolution? Does it manipulate host brain directly, bending it to its will? Or does the infection cause the host's immune response to go haywire, causing inflammation in the brain that leads to behavioral changes?
New research,, attempts to answer those questions. Researchers examined behavioral changes in mice as a result of Toxoplasma infection, subjecting the rodents to an array of behavioral tests to determine if they were less fearful of predator odors and open spaces. Then they dug into the brain, focusing their attention on parasitic cysts and genetic markers of inflammation, to determine if tangible physiological changes contributed to mice behavior.

Can a parasite control your mind ? A Toxoplasma gondii tissue cyst. The parasite can move from its feline host to humans, most commonly through contact with cat feces. And while the parasite typically only causes mild infection (people may have flulike symptoms), in people with weakened
There is a single-celled parasite called Toxoplasma gondii, which is found in domestic cats, and is estimated to infect 350,000 people a year in Britain. We've not looked at behavioral changes in people infected with toxoplasma , as that's been dealt with by previous studies ," says Dr Barragan.
"There has been a lot of controversy around the question of whether general anxiety is lowered or not," says PhD student Madlaina Boillat, neurogeneticist at the University of Geneva and co-first author on the paper. "Studies have reported either no change in anxiety upon infection, increased anxiety or lowered anxiety, depending on variables such as the behavioral assay that was used and on infection level, which is highly dependent on mouse strain and parasite strain."
In one behavioral test, mice were placed in an X-shaped "maze". Two arms of the X were bordered by large walls and two arms were completely open. Non-infected mice usually stick to the arms containing border walls for safety, but mice infected with the parasite spent a lot more time exploring the open arms. Another test, Boillat explains, showed infected individuals were willing to sniff out fox and guinea pig odors just as readily.
This new finding is particularly important because it demonstrates the parasite does not selectively manipulate host behavior to be less fearful of cats as the so-called theory of "fatal attraction" suggests. The rodents don't perform a scan specifically seeking out cats. Instead, it appears the parasite likely tinkers with more generalized anxiety pathways in the brain and causing an increase in curiosity.

Mind alteration in animals infected by parasites is a relatively new field of study . And what easier way than to just take control of your host by changing their behavior mentally? The concern began when people realized that what altered rodent behavior might change human behavior, too.

The physiological response is telling.
"Our RNA-sequencing experiment shows there are major changes occurring in the brain [of] infected mice," says Boillat. "Highly infected mice show signs of immunopathology, such as neuronal death and excitotoxicity."
The severity of these symptoms were related to how many ball-like cysts formed and how much inflammation was seen in mouse brains. It follows then that Toxoplasma doesn't directly mess with brain cells, somehow pulling the strings in a rodent's grey matter for its own benefit, but rather drives inflammation. This follows: When cysts and inflammation increased, so did the activity level of infected mice.
Rather than the (admittedly very cool) idea the parasite is performing some sort of mind control, it seems likely the immune response is driving the unusual -- and potentially fatal -- behaviors. Such a finding could have far-reaching implications if it holds up in humans, too.
"It is known that an inflammation in the brain, whether it is induced by Toxoplasma gondii or other pathogens, can act as a trigger for mental illnesses in humans," Boillat notes. However, she suggests we should be "very cautious" in interpreting the results. Yes, the team observed strong correlations between infection, gene expression in the brain and behavior but they cannot provide any causative explanations, yet.
Moreover, , making it difficult to draw direct comparisons between species.
The team's next challenge is to understand how inflammation in the brain can drive behavioral changes in the mouse. Is it because brain cells are being over-stimulated in some way or are the molecular signals going haywire? Does the parasite's presence change the way the brain responds to stimuli?
Answering those questions will shed further light on Toxoplasma's purported mind-control techniques and, as an aside, help me look at the neighborhood tabby without being terrified.
“Parasite” could (also) be adapted as a series
Definitely, theat the never ceases to be talked about. Praised by critics and the general public around the world and with an undeniable success at the box office, the film Bong Joon-ho no longer seems to be able to stop its mad rush. While was mentioned last July (and is still under study at the moment), we have learned that the feature film could this time be adapted in series.
According to, the HBO channel is currently in talks with the Korean director as well as with his American colleague , to make a mini-series. Like Bong Joon-ho, McKay is one of the most prominent directors of the moment: acclaimed for The Big Short and Vice, he has just won the for the best drama series for . As for the Korean filmmaker, many predict him a brilliant victory at the , in the category best international film but also best director, best screenplay or even best film. In short, you haven't finished hearing about Parasite.
