Shooting Star
The European Space Agency's Facebook page shows a sped-up timelapse of the module, called Pirs, meeting its fiery demise Monday (July 26) under the watch of Thomas Pesquet.
"Atmospheric reentry without a heat shield results in a nice fireball," Pesquet wrote in the post, which also included a French description. "You clearly see smaller pieces of melting metal floating away and adding to the fireworks." READ MORE

Backside of Black Hole
Einstein's 1915 Theory of General Relativity predicted that the gravitational pull of black holes is so large that black holes warp the fabric of space, according to The Telegraph.
As reported by The Telegraph, a new Nature report proves Einstein's theory correct.
"Fifty years ago, when astrophysicists started speculating about how the magnetic field might behave close to a black hole, they had no idea that one day we might have the techniques to observe this directly and see Einstein's general theory of relativity in action," Standford University professor and research report co-author, Roger Blandford, said.
Einstein's theory stated that because of how black holes warp the space fabric around them, it should be possible to see light waves ejected out of a black hole's backside as the twisted magnetic fields act as a mirror for the black hole.

Living With Cancers & Heart Disease
For the last 13 (almost 14 years) I have been dealing with heart disease from the standpoint of having a heart attack from 3 blocked heart arteries and 5 stents inserted. Results are that my heart is working normally but I have to be really careful with what I am eating and really careful with my physical exertion so as not to overdo it. I have handicapped liscense plates because I can no longer walk very far without being out-of-breath.
For the last 13 (almost 14 years) I have been dealing with preventing two types of cancers from simultaneously growing in my body and for the first 10 years was not that successful but for the last 3 years have been relatively successful...
During the last 13 years, I have experienced surgery, chemotheraphy, immunotherapy, and radiation. My treatments have caused me to experience nausea, fatigue, anemia, and a destroyed immune system along with damaging my thyroid.
The treatments that I took to suppress my Lymphoma caused me to contract Melanoma which from the getgo was very aggressive and moved from my foot to my groin to my neck... however, once it got to my neck and was surgically removed, the cancer cells were all dead.
I get a PET scan or a CT scan every 3 months to see if my cancers are displaying any metabolic activity. My next scan is this coming Monday or in two days.
Other than having cancers hanging over your head and having to watch what you eat, and how you must dress when out in the sun, I am living a relatively normal life.
I don't eat red meat except for maybe once or twice a year. I don't eat fried foods except for maybe once or twice a year. I stay away from sugar but that is not as easy as it sounds.
I eat veges, chicken, veal, a variety of beans, and fish mainly. The fish I prefer is Salmon, Cod, and Flounder.
Giant Vampire Bat
First described in 1988, its fossils are known from Argentina, Mexico, Ecuador, Brazil, Venezuela, Belize, and Bolivia.
Desmodus draculae had a wingspan of up to 50 cm (20 inches) and a body mass of 60 g, making it the largest known vampire bat of all time.
It belongs to the subfamily Desmodontinae (vampire bats), which also includes three extinct and three living species.
“The size of Desmodus draculae was larger than that of a computer keyboard and significantly larger than that of its living relatives,” said Dr. Santiago Brizuela, a paleontologist at the Universidad Nacional de Mar del Plata and CONICET.
The food source of Desmodus draculae and other vampire bats is blood, a dietary trait called hematophagy. READ ENTIRE ARTICLE

Dopamine
From the thrill of hearing an ice cream truck approaching to the spikes of pleasure while sipping a fine wine, the neurological messenger known as dopamine has been popularly described as the brain’s “feel good” chemical related to reward and pleasure.
A ubiquitous neurotransmitter that carries signals between brain cells, dopamine, among its many functions, is involved in multiple aspects of cognitive processing.

Life in the Valley
BLM Accomplished NOTHING
We are in the process of ending another week... and, I am looking at the last weekend before the next week begins and I find myself with 4 medical appointments... a CT scan, fasting blood work, an IVIG infusion, and an Opdivo Infusion... then, there is another complete week before we leave, two weeks from today, for Myrtle Beach...
The morning news is always the same ole shit from the day before just reheated a little like leftovers. The immigrants coming into our souther border is out-of-control... There is an increase in violence in many of our major cities... the Democrats want to spend money faster than a daily bowel movement... and, we still cannot decide whether to wear facemasks or not or if students should return to school...
ALL I CAN SAY TO ALL OF THIS IS WTF???
I look back on this last year and the focus that has been given on BLACK LIVES MATTER, tearing down confederate statues, renaming buildings, taking money away from law enforcement, and making the claim that America is a RACIST country and we should be ashamed to live here because of our heritage and past history.
Has the Black Lives Matter movement really changed anything?
I don't believe anything in the black communities has changed at all...
I know nothing has changed in whte communities...
But, isn't it interesting that I say describe life in the USA like that as if it is as normal as can be... white and black communities... how in the world are we supposed to change our racist beliefs if we still continue to live in those two completely different types of communities???
Because of all the media coverage as to how bad the white man is, I am not only offended by the implications of that statement but now I am going to bend over backwards to never have anything to do with BLACK PEOPLE... If I am so bad, let them stay away from me... and, I will stay away from them!!!
Black Lives Matter will always be associated with marches, violence, protests, burning, and looting... IT WILL NEVER BE ASSOCIATED WITH CHANGE...
Remote Working Employees
The COVID-19 pandemic forced these companies to operate with mostly remote workforces for months straight.
But thousands of high-paid workers at these companies aren't having it. Many of them don't want to go back to the office full time, even if they're willing to do so a few days a week.
Disk Around Exoplanet
ANDY TOMASWICK, UNIVERSE TODAY 26 JULY 2021
Planetary formation is a complicated, multilayered process. Even with the influx of data on exoplanets, there are still only two known planets that are not yet fully formed.
Known as PDS 70b and PDS 70c, the two planets, which were originally found by the Very Large Telescope, are some of the best objects we have to flesh out our planetary formation models.
Optical Illusions
Titled They Can Disappear, this illusion by Russian artist Ilja Klemencov was created for the World Wildlife Fund for Nature (WWF), and features the organisation's iconic panda logo (arguably one of the best logos around) – you'll just have to squint to see it.

Stare at those zigzag lines for long enough, and you might eventually be able to make out the shape of the Panda. Klemencov's design is an example of an illusion known as the McCollough effect. Discovered in 1965 by Celeste McCollough, the illusion is a "phenomenon of human visual perception in which colourless gratings appear colored contingent on the orientation of the gratings," (thanks, Wikipedia).
Brain Cancer and Mitochondria
One in Five Brain Cancers Fueled by Overactive Mitochondria
Mitochondria are responsible for creating the energy that fuels all cells. Though they are usually less efficient at producing energy in cancer, tumor cells in this newly identified type of glioblastoma rely on the extra energy provided by overactive mitochondria to survive.
The study, by cancer scientists at Columbia University’s Vagelos College of Physicians and Surgeons and Herbert Irving Comprehensive Cancer Center, was published in Nature Cancer.
The study also found that drugs that inhibit mitochondria—including a currently available drug and an experimental compound that are being tested in clinical trials—had a powerful anti-tumor effect on human brain cancer cells with overactive mitochondria. (Follow-up, unpublished work found that the same drugs are also active against mitochondrial tumors in glioblastomas growing in mice).
Such drugs are being tested in patients who have a rare gene fusion—previously discovered by the same researchers—that also sends mitochondria into overdrive.
“We can now expand these clinical trials to a much larger group of patients, because we can identify patients with mitochondria-driven tumors, regardless of the underlying genetics,” says Antonio Iavarone, MD, professor of neurology, who led the study with Anna Lasorella, MD, professor of pediatrics. Both are members of Columbia’s Institute for Cancer Genetics.
Study finds four types of brain cancer

The study found that all brain cancers fall into one of four groups, including the mitochondrial subtype.
By classifying brain cancers based on their core biological features, and not just genetic alterations or cell biomarkers, the researchers have gained new insights into what drives each subtype and the prognosis for patients.
“Existing classifications for brain cancer are not informative. They don’t predict outcomes; they don’t tell us which treatments will work best,” Lasorella says.
The importance of an accurate classification system is best illustrated by the example of breast cancer. Breast cancers have very well-defined subtypes that led to the development of therapies that target the key hallmarks, such as estrogen receptors or HER2, that sustain specific subtypes.
“We feel that one of the reasons therapeutic progress in brain cancer has been so slow is because we don't have a good way to classify these tumors,” Iavarone says.
Glioblastoma is the most common—and most lethal—primary brain tumor in adults. Median survival for individuals with glioblastoma is only 15 months.
The new study showed that glioblastoma can be classified in four biological groups. Two of them recapitulate functions active in the normal brain, either stem cells or neurons, respectively. The two other groups include mitochondrial tumors and a group of tumors with multiple metabolic activities (“plurimetabolic”) that are highly resistant to current therapies.
Patients with the mitochondrial tumors had a slightly better prognosis—and lived for a few more months—than patients with the other three types.
“We are excited about the mitochondrial group, because we have drugs for that group in clinical trials already,” Lasorella says, “but the classification now gives us ideas about how to target these other three and we are starting to investigate these more intensely.”
“We’re going beyond one mutation, one drug concept,” she says. “Sometimes it’s possible to get a response that way. But it’s time to target tumors based on the commonalities of their core biology, which can be caused by multiple different genetic combinations.”
Single-cell analyses opens new view of brain cancer
The new findings were only possible by utilizing recent advances in single-cell analyses, which allowed the scientists to understand—cell by cell—the biological activity of thousands of cells from a single tumor.
Overall, the scientists characterized the biological properties of 17,367 individual cells from 36 different tumors.
In addition to analyzing each cell’s genetic mutations and levels of gene activity, the researchers looked at other modifications made to the cells’ genomes and the proteins and noncoding RNAs made by each cell.
Using the data, the researchers devised a computational approach to identify core biological processes, or pathways, in the cells rather than the more common approach of identifying gene signatures. “In this way, we can classify each individual tumor cell based on the real biology that sustains them,” Iavarone says.
Most tumors, the researchers found, were dominated by cells from one of the four subtypes, with a smattering of cells from the other three.
Applying same techniques to other cancers
Lasorella and Iavarone are now applying the same techniques to multiple different aggressive cancers.
This “pan-cancer” approach, they say, should identify commonalities among different types of cancer regardless of the tumor’s origin. If such common pathways exist, drugs that treat mitochondrial brain cancer may also be able to treat mitochondrial types of lung cancer, for example.
“When we classify based on the cell’s core biological activities, which all cells rely on to survive and thrive, we may find that cancers share more in common than was previously apparent by just looking at their genes,” Lasorella says.
