Heat-Loving Microbes, Once Dormant, Thrive Over Decades-Old Fire
In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.
The earth vents steam in Centralia, Pennsylvania, a town that was largely abandoned because of subterranean fires that have burned for decades. In places, the soil gets scorchingly hot, but some microbial life that was dormant at more normal temperatures now flourishes there.

Israeli scientists manage to print artificial heart with patient's cells for the first time ever

The process of creating the heart started with a biopsy of fatty tissue taken from patients. The cellular material from the tissues was used as the "ink" for the print job. That allowed researchers to create complex tissue models including cardiac patches and eventually an entire heart. It should be noted that the heart isn't very big -- it's only about the size of a rabbit's heart. But the technology that made it possible could eventually lead to the production of a human-sized organ. Currently, the hearts can only contract but researchers plan on culturing the 3D printed hearts and teaching them how to operate like the real deal. Once that process is complete, they will attempt to transplant them into animal models.

Sleep myths 'damaging your health' | BBC News

Widely held myths about sleep are damaging our health and our mood, as well as shortening our lives, say researchers.
A team at New York University trawled the internet to find the most common claims about a good night's kip.
Then, in a study published in the journal Sleep Health, they matched the claims to the best scientific evidence.
They hope that dispelling sleep myths will improve people's physical and mental health and well-being.

Baby with DNA by three parents successfully born

After four cycles of in vitro fertilization failed to result in a pregnancy, the Greek couple enrolled in a clinical trial for mitochondrial replacement therapy (MRT) — meaning doctors placed the nucleus from the mother’s egg into a donor egg that had its nucleus removed. Then they fertilized the egg with sperm from the father and implanted it into the mother.

“Our excellent collaboration and this exceptional result will help countless women to realise their dream of becoming mothers with their own genetic material,” Nuno Costa-Borges, co-founder of Embryotools, one of the companies behind the trial, said in a statement.

Scientists have implemented human genes in monkey's brain

Now scientists in southern China report that they’ve tried to narrow the evolutionary gap, creating several transgenic macaque monkeys with extra copies of a human gene suspected of playing a role in shaping human intelligence.

According to their findings, the modified monkeys did better on a memory test involving colors and block pictures, and their brains also took longer to develop—as those of human children do. There wasn’t a difference in brain size.
Hasn't it already been proven that the actual size of a brain doesn't determine its power, its efficiency or someone's overall intelligence? I may recall having heard something like this.
Instead, several Western scientists, including one who collaborated on the effort, called the experiments reckless and said they questioned the ethics of genetically modifying primates, an area where China has seized a technological edge.
The everlasting ethics debate in sicence...
Su’s monkeys raise some unusual questions about animal rights. In 2010, Sikela and three colleagues wrote a paper called “The ethics of using transgenic non-human primates to study what makes us human,” in which they concluded that human brain genes should never be added to apes, such as chimpanzees, because they are too similar to us.

Archaeologists discover new human species

The small-bodied hominin, named Homo luzonensis, lived on the island of Luzon at least 50,000 to 67,000 years ago. The hominin—identified from a total of seven teeth and six small bones—hosts a patchwork of ancient and more advanced features. The landmark discovery, announced in Nature on Wednesday, makes Luzon the third Southeast Asian island in the last 15 years to bear signs of unexpectedly ancient human activity.

“This new discovery made me thrilled,” Yousuke Kaifu, a paleoanthropologist at Tokyo's National Museum of Nature and Science who was not part of the new study, says via email. “It further highlights remarkable diversity of archaic (primitive) hominins once present in Asia, in a way beyond my expectation.”

“ [If]in the future, colleagues are able to show that we were wrong because the fossils can enter one of the already known hominin species, we will just lump it and forget about it, but in the meantime, I am convinced it is the way we had to do it,” he says via email.

The Center Cannot Hold by Elyn R. Saks

I am seven, or eight, standing in the cluttered living room of our comfortable house, looking out at the sunny day.
“Dad, can we go out to the cabana for a swim?”
He snaps at me, “I told you I have work to do, Elyn, and anyway it might rain. How many times do I have to tell you the same thing? Don’t you ever listen?”
My heart sinks at the tone of his voice: I’ve disappointed him.

And then something odd happens. My awareness (of myself, of him, of the room, of the physical reality around and beyond us) instantly grows fuzzy. Or wobbly. I think I am dissolving. I feel—my mind feels—like a sand castle with all the sand sliding away in the receding surf. What’s happening to me? This is scary, please let it be over! I think maybe if I stand very still and quiet, it will stop.
This experience is much harder, and weirder, to describe than extreme fear or terror. Most people know what it is like to be seriously afraid. If they haven’t felt it themselves, they’ve at least seen a movie, or read a book, or talked to a frightened friend—they can at least imagine it. But explaining what I’ve come to call “disorganization” is a different challenge altogether. Consciousness gradually loses its coherence. One’s center gives way. The center cannot hold. The “me” becomes a haze, and the solid center from which one experiences reality breaks up like a bad radio signal. There is no longer a sturdy vantage point from which to look out, take things in, assess what’s happening. No core holds things together, providing the lens through which to see the world, to make judgments and comprehend risk. Random moments of time follow one another. Sights, sounds, thoughts, and feelings don’t go together. No organizing principle takes successive moments in time and puts them together in a coherent way from which sense can be made. And it’s all taking place in slow motion.

Of course, my dad didn’t notice what had happened, since it was all happening inside me. And as frightened as I was at that moment, I intuitively knew this was something I needed to hide from him, and from anyone else as well. That intuition—that there was a secret I had to keep—as well as the other masking skills that I learned to use to manage my disease, came to be central components of my experience of schizophrenia.

First photo of a black hole taken in Messier 87 galaxy

“We have seen what we thought was unseeable. We have seen and taken a picture of a black hole,” Sheperd Doeleman, EHT Director and astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., said April 10 in Washington, D.C., at one of seven concurrent news conferences. The results were also published in six papers in the Astrophysical Journal Letters.

That's because black holes are notoriously hard to see. Their gravity is so extreme that nothing, not even light, can escape across the boundary at a black hole's edge, known as the event horizon. But some black holes, especially supermassive ones dwelling in galaxies’ centers, stand out by voraciously accreting bright disks of gas and other material. The EHT image reveals the shadow of M87’s black hole on its accretion disk. Appearing as a fuzzy, asymmetrical ring, it unveils for the first time a dark abyss of one of the universe’s most mysterious objects.

“Black hole environments are a likely place where general relativity would break down,” says EHT team member Feryal Özel, an astrophysicist at the University of Arizona in Tucson. So testing general relativity in such extreme conditions could reveal deviations from Einstein’s predictions.
