Back in May, China became just the third nation to land on the surface of Mars as it touched down with its Tianwen-1 probe. Packed aboard was the country’s first interplanetary rover, named Zhurong, which can be seen and heard making its very movements on the Red Planet in newly released recordings.

China’s Tianwen-1 mission set off for Mars last July and came to land on a plain in the planet’s northern hemisphere called Utopia Planitia following a 10-month journey. The Zhurong rover remained aboard the lander module for around a week surveying its surroundings and checking its instruments, before rolling down to the dusty surface to begin its explorations.

Recordings gathered by the China National Space Administration and shared by state-funded broadcaster CCTV show the rover’s start to life on Mars in intriguing new light. The first includes the first audio collected by a Chinese Mars rover, with an onboard recording device capturing the sounds as its engine was started, of the Martian winds and of the machinations of the robot as it made its way down to the surface.

A team of researchers at Tel Aviv University has developed a breakthrough RNA-based drug delivery system to target diseased cells that could improve the treatment of blood cancers, various types of solid cancers, different inflammatory diseases and viral diseases – including coronavirus.


“We are the first in the world to deliver the drug exclusively to cells that are currently relevant to the disease.”

Of the 88 neurosurgical patients, 30 showed a decrease in self-reported spiritual belief before and after neurosurgical brain tumor resection, 29 showed an increase, and 29 showed no change. Using lesion network mapping, the team found that self-reported spirituality mapped to a specific brain circuit centered on the PAG. The circuit included positive nodes and negative nodes — lesions that disrupted these respective nodes either decreased or increased self-reported spiritual beliefs.


Summary: A new study has identified a specific brain circuit centered in the periaqueductal gray that is linked to spiritual acceptance and religiosity.

More than 80 percent of people around the world consider themselves to be religious or spiritual. But research on the neuroscience of spirituality and religiosity has been sparse. Previous studies have used functional neuroimaging, in which an individual undergoes a brain scan while performing a task to see what areas of the brain light up. But these correlative studies have given a spotty and often inconsistent picture of spirituality.

“I realized that in the middle-dose group, which is the one that mattered for the no-effects level, they had conveniently left out one of the two baseline measurement days,” said Sheppard. “The outrageous thing was that the group they declared as NOEL was only that because they left out data from their analysis.” In a peer-reviewed paper published in October 2020, Sheppard and her colleagues concluded that “the omission of valid data without justification was a form of data falsification.”


In any case, bifenthrin was not the only pesticide that dodged testing to see if it presented dangers. The EPA’s pesticide office granted 972 industry requests to waive toxicity tests between December 2011 and May 2018, 89 percent of all requests made. Among the tests on pesticides that were never performed were 90 percent of tests looking for developmental neurotoxicity, 92 percent of chronic cancer studies, and 97 percent of studies looking at how pesticides harm the immune system.

By law, the companies that submit their products for review pay for these tests, and in a presentation about the waivers last year, Anna Lowit, a senior science adviser in the office, emphasized the savings to these companies: more than $300 million. Lowit also noted that animal lives were saved — a goal that the Trump administration and the chemical industry prioritized within the agency. The EPA developed the guidelines for waiving the tests along with BASF, Corteva, and Syngenta, pesticide manufacturers that all stand to benefit significantly from having their products bypass toxicity testing.

There is no replacement for these waived experiments, according to pediatrician and epidemiologist Philip Landrigan. “There is no other way to know if a chemical is toxic but to test it,” said Landrigan, who co-authored a landmark report on children’s particular vulnerability to pesticides. “If they allow chemicals to come onto the market and to be used widely in the environment and put on food crops without testing them for toxicity, then EPA is clearly not fulfilling its mandate to protect human health.”

Not everything that is true can be proven. This discovery transformed infinity, changed the course of a world war and led to the modern computer. This video is sponsored by Brilliant. The first 200 people to sign up via https://brilliant.org/veritasium get 20% off a yearly subscription.

Not just the results, but the vector used. I’ll post the paper below.


In this video we cover an experiment where gene therapies to overexpress TERT and Follistatin were used in a mouse model. The mice saw a 41 and 32% increase in median life span. The study also used a novel viral vector, cytomegalovirus for the delivery. Please note that this a preprint which is not peer-reviewed yet.

New research shows how the fundamental law of conservation of charge could break down near a black hole.

Singularities, such as those at the centre of black holes, where density becomes infinite, are often said to be places where physics ‘breaks down’. However, this doesn’t mean that ‘anything’ could happen, and physicists are interested in which laws could break down, and how.

Now, a research team from Imperial College London, the Cockcroft Institute and Lancaster University have proposed a way that singularities could violate the law of conservation of charge. Their theory is published in Annalen der Physik.

Wally Funk was one of 13 female aviators who lobbied for women to become astronauts in the early days of spaceflight.


Aviator Wally Funk wanted to be an astronaut in the earliest days of spaceflight. Sixty years later, on July 20, she’ll finally go to space with Blue Origin.

Funk was one of 13 female aviators later dubbed the Mercury 13 who, in 1961, passed all the exams necessary for admission to NASA’s astronaut corps and lobbied the federal government to send women into space. NASA and Congress demurred and women were excluded from becoming U.S. astronauts for more than a decade; Sally Ride became the first American woman to fly in space in 1983.
