'Past a point of no return': Reducing greenhouse gas emissions to zero still won't stop global warming
Even if human-caused greenhouse gas emissions can be reduced to zero, global temperatures may continue to rise for centuries afterward, according to a scientific study published Thursday.
"The world is already past a point of no return for global warming," the study authors report in the British journal Scientific Reports. The only way to stop the warming, they say, is that "enormous amounts of carbon dioxide have to be extracted from the atmosphere."
The burning of fossil fuels such as oil, coal and gas release greenhouse gases such as carbon dioxide and methane into the atmosphere, causing global temperatures to increase and sea levels to rise.
The scientists modeled the effect of greenhouse gas emission reductions on changes in the Earth's climate from 1850 to 2500 and created projections of global temperature and sea level rises.

Mystery of Denisovans, a Sister Species of Modern Humans
“This fossil represents the first discovery of Denisovans in Southeast Asia and shows that Denisovans were in the south at least as far as Laos. This is in agreement with the genetic evidence found in modern-day Southeast Asian populations.”

Size DOES matter!
Reducing the depth of penetration by an inch led to a statistically meaningful drop in the amount of pleasure experienced.
'The longer the erect penis, the less likely the rings had an impact on sexual pleasure,' they write.

'everyone knows it's wrong'
Scientists created the world's whitest paint. It could eliminate the need for air conditioning.
The paint reflects 98.1% of solar radiation while also emitting infrared heat. Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power.

WHAT'S THE MATTER WITH DARK MATTER? OBSERVATIONS SHOW WE'RE MISSING SOMETHING.
New results gathered from observations of galaxy clusters with Hubble and the Very Large Telescope have shown that the Universe — and this is a consistently irritating property of it — isn't performing as our physics thinks it should.
In this case the focus is on dark matter. When you look at all the matter in the Universe, what we think of as "normal" matter — stuff made up of electrons, neutrons, protons, and so on — is in the distinct minority. Only about one-sixth of all matter is normal; the rest is dark matter.

Why Are Smokers Being Hospitalized Less Often From Coronavirus?
The Chinese smoke. Well over half the nation's men are smokers, and the World Health Organization (WHO) estimates that one third of the planet's cigarettes are smoked in China. But earlier this year, Konstantinos Farsalinos noticed something odd: Very few of those hospitalized for the coronavirus in the country appeared to be smokers.
Farsalinos, a cardiologist and tobacco harm-reduction specialist in Greece, has since been wondering if nicotine, the chemical substance found in tobacco, could be preventing people from getting COVID-19, or stopping the symptoms from becoming worse.
While no conclusions can yet be drawn, Farsalinos' prevailing hypothesis is essentially that nicotine has certain anti-inflammatory effects. The most severe COVID-19 symptoms seem to come from an overreaction of the body's immune system known as a "cytokine storm." During that storm, the immune system targets an infection, say in the lungs, and they can become inflamed, leading to difficulty breathing. Nicotine, Farsalinos reasons, might be able to at least lessen that intensity.

Scientists edited genes inside of a live patient for the first time
For the first time ever, scientists edited the DNA inside a living human being. Doctors at Harvard edited the unruly cellular material of a live patient — who has a rare genetic disorder that causes blindness — inside the patient’s body, reported NPR. CRISPR, the technology used to edit the cellular sequence, isn’t brand new. But usually in order to use it for DNA editing, doctors first remove cells from a patient’s body, edit the genes inside them, and then put the edited genes back into the patient. Not anymore, though, apparently. CRISPR has now been used to modify DNA without first removing the cells, according to NPR.
In order to achieve this groundbreaking medical feat, doctors injected the patient’s eye with a combination of viruses and a set of CRISPR-created instructions for editing the gene, NPR reported. The viruses themselves are harmless. They are used as messengers to deliver the gene edits to the cells. The tool sent by the viruses is intended to cut out the defect that causes blindness in the patient. According to NPR, scientists hope that by cutting out the malfunctioning part of the cell, the patient’s body will respond by producing necessary proteins that prevent the death of cells in the retina and will also revitalize other cells, thus restoring vision.

A hormone found in chocolate may boost men’s sex drive
Doctors in the future may treat men suffering from low sex drive with an injection of a hormone found in chocolate.
A new study has just found kisspeptin boosted how men’s brains respond to attractive faces and scent.
It could help the one-in-three people who suffer from ‘psychosexual disorders’. These include not getting aroused or satisfied by sex.

A LAB GREW A “MINI BRAIN” FROM THIS GUY’S CELLS. THEN THINGS GOT WEIRD.
When science writer Philip Ball donated some flesh from his arm to a neuroscience lab growing “mini brains,” he originally intended to contribute to research into the biological mechanisms of dementia.
Instead, he ended up with a simplified genetic replica of his own brain growing in a petri dish — and found himself questioning what makes us human, according to a new review of Ball’s upcoming book published in Nature.

WHAT IF AIR CONDITIONERS COULD HELP SAVE THE PLANET INSTEAD OF DESTROYING IT?
EARTH’S CLIMATE IS full of terrifying feedback loops: Decreased rainfall raises the risk of wildfires, which release yet more carbon dioxide. A warming Arctic could trigger the release of long-frozen methane, which would heat the planet even faster than carbon. A lesser-known climate feedback loop, though, is likely mere feet from where you’re sitting: the air conditioner. Use of the energy-intensive appliance causes emissions that contribute to higher global temperatures, which means we’re all using AC more, producing more emissions and more warming.
But what if we could weaponize air conditioning units to help pull carbon dioxide out of the atmosphere instead? According to a new paper in Nature, it’s feasible. Using technology currently in development, AC units in skyscrapers and even your home could get turned into machines that not only capture CO2, but transform the stuff into a fuel for powering vehicles that are difficult to electrify, like cargo ships. The concept, called crowd oil, is still theoretical and faces many challenges. But in these desperate times, crowd oil might have a place in the fight to curb climate change.

SCIENTISTS SAY THEY CAN MAKE LIGHT TRAVEL 30X FASTER THAN NORMAL
Scientists at the University of Central Florida say they’ve figured out how to make pulses of light travel 30 times as fast as usual — or even backward.
“We’re able to control the speed of the pulse by going into the pulse itself and reorganizing its energy such that its space and time degrees of freedom are mixed in with each other,” researcher Ayman Abouraddy said in a statement. “We’re very happy with these results, and we’re very hopeful it’s just the starting point of future research.”
