Scientists think they’ve detected radio emissions from an alien world

Scientists may have detected radio emissions from a planet orbiting a star beyond our sun for the first time.

The astronomers behind the new research used a radio telescope in the Netherlands to study three different stars known to host exoplanets. The researchers compared what they saw to observations of Jupiter, diluted as if being seen from a star system dozens of light-years away. And one star system stood out: Tau Boötes, which contains at least one exoplanet. If the detection holds up, it could open the door to better understanding the magnetic fields of exoplanets and therefore the exoplanets themselves, the researchers hope.

“We present one of the first hints of detecting an exoplanet in the radio realm,” Jake Turner, an astronomer at Cornell University and lead author of the new research, said in a statement. “We make the case for an emission by the planet itself. From the strength and polarization of the radio signal and the planet’s magnetic field, it is compatible with theoretical predictions.”

France Says It’s Developing Bionic Supersoldiers Because “Everyone Else Is Doing It”

A report published last Tuesday by the French Military Ethics Committee has indicated that the country has begun to develop technology for bionically enhanced soldiers. The report discussed conditions in which devices like implants can be used to improve soldier performance on the battlefield.

“Human beings have long sought ways to increase their physical or cognitive abilities in order to fight wars. Possible advances could ultimately lead to capacity enhancements being introduced into soldiers’ bodies,” the report said, according to the BBC.

The report said that maintaining clear ethical lines would be important in the development of bionic soldiers. The report called for eugenic or genetic applications of the technology to be banned, as well as anything “that could jeopardise the soldier’s integration into society or return to civilian life”.

The country’s military leaders believe that it is necessary to develop this technology because not doing so would allow other countries to get ahead and gain a military advantage.

In a speech last week, Defence Minister Florence Parly, said that the country’s military doesn’t plan on developing anything extremely “invasive” right away, but said that this could be an option in the future because other countries will be pushing the technology as far as they can.

“We must face the facts. Not everyone shares our scruples and we must be prepared for whatever the future holds,” Parly said.

Parly went on to promise that the French government would seek to find a balance, and will find “ways to maintain our operational superiority without turning our backs on our values.”

Parly also pointed out that similar technologies, such as neural implants, have already been introduced to civilian fields without much controversy.

The Strangely Unscientific Masking Of America

I remember vividly the day, at the tail end of March, when facemasks suddenly became synonymous with morality: either one cared about the lives of others and donned a mask, or one was selfish and refused to do so. The shift occurred virtually overnight. 

Only a day or two before, I had associated this attire solely with surgeons and people living in heavily polluted regions. Now, my friends’ favorite pastime during our weekly Zoom sessions was excoriating people for running or socializing without masks in Prospect Park. I was mystified by their certitude that bits of cloth were the only thing standing between us and mass death, particularly when mere weeks prior, the message from medical experts contradicted this new doctrine.

Scientists Accidentally Created A Hybrid Of Two Fish That Last Shared An Ancestor In The Jurassic Period

With a little help from Hungarian scientists, the seemingly impossible just occurred — the birth of long-nosed, spiky-finned hybrids of Russian sturgeons and American paddlefish. Though the results were accidental, about 100 of these so-called “sturddlefish” are now in captivity.

According to LiveScience, the Research Institute for Fisheries and Aquaculture in Hungary scientists didn’t intend to birth this entirely new species. After all, 184 million years of evolution on separate continents made it seem clear that these two kinds of fish were sexually incompatible.

After placing sperm from an American paddlefish near eggs from a Russian sturgeon, however, they were proven wrong. According to ScienceAlert, the eggs reproduced asexually through gynogesis, a process that requires the presence of sperm but not the actual introduction of its DNA.

How Universities Cover Up Scientific Fraud

One in fifty scientists fakes research by fabricating or falsifying data. They make off with government grant money, which they share with their universities, and their made-up findings guide medical practice, public policy and ordinary people’s decisions about things like whether or not to vaccinate their children. The fraudulent science we know about has caused thousands of deaths and wasted millions in taxpayer dollars. That is only scratching the surface, however—because most fraudsters are never caught. As Ivan Oransky notes in Gaming the Metrics, “the most common outcome for those who commit fraud is: a long career.”

Scientists splice human genes into monkey brains to make them bigger, smarter

What could go wrong?

Scientists made monkey brains double in size by splicing them with human genes in a “Planet of the Apes”-style experiment.

During the study, Japanese and German researchers injected a gene called ARHGAP11B — which directs stem cells in the human brain — into the dark matter of marmoset fetuses, according to a release about the research.

They found that the primates’ brains soon became more human-like by developing larger, more advanced neocortexes — the area that controls cognition and language, according to the study published in the journal Science in June.

According to images released by the researchers, the modified monkey brains nearly doubled in size at around 100 days into gestation.
