Science X Newsletter Week 27

Dear Reader ,

Here is your customized Science X Newsletter for week 27:

	Global warming may be twice what climate models predict A new study based on evidence from past warm periods suggests global warming may be double what is forecast.
	Feeling young could mean your brain is aging more slowly While everyone gets older, not everyone feels their age. A recent study finds that such feelings, called subjective age, may reflect brain aging. Using MRI brain scans, researchers found that elderly people who feel younger than their age show fewer signs of brain aging, compared with those who feel their age or older than their age. Published in open-access journal Frontiers in Aging Neuroscience, this study is the first to find a link between subjective age and brain aging. The results suggest that elderly people who feel older than their age should consider caring for their brain health.
	Study finds no strong evidence that cannabis reduces chronic pain A four-year study suggests medicinal cannabis is not as effective at relieving chronic non-cancer pain as commonly assumed.
	Metformin reverses established lung fibrosis Researchers at the University of Alabama at Birmingham have shown—for the first time—that established lung fibrosis can be reversed using a drug treatment that targets cell metabolism.
	Nuts may boost male fertility: study Eating nuts "significantly" boosted the number and health of sperm in young men in a scientific trial, researchers said Wednesday.
	First confirmed image of newborn planet caught with ESO's VLT Astronomers led by a group at the Max Planck Institute for Astronomy in Heidelberg, Germany have captured a spectacular snapshot of planetary formation around the young dwarf star PDS 70. By using the SPHERE instrument on ESO's Very Large Telescope (VLT)—one of the most powerful planet-hunting instruments in existence—the international team has made the first robust detection of a young planet, named PDS 70b, cleaving a path through the planet-forming material surrounding the young star.
	Neuroscientists uncover secret to intelligence in parrots University of Alberta neuroscientists have identified the neural circuit that may underlie intelligence in birds, according to a new study. The discovery is an example of convergent evolution between the brains of birds and primates, with the potential to provide insight into the neural basis of human intelligence.
	'Cataclysmic' collision shaped Uranus' evolution Uranus was hit by a massive object roughly twice the size of Earth that caused the planet to tilt and could explain its freezing temperatures, according to new research.
	Einstein gets it right again—weak and strong gravity objects fall the same way Einstein's understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their mass or composition. This theory has passed test after test here on Earth, but does it still hold true for some of the most massive and dense objects in the known universe, an aspect of nature known as the Strong Equivalence Principle? An international team of astronomers has given this lingering question its most stringent test ever. Their findings, published in the journal Nature, show that Einstein's insights into gravity still hold sway, even in one of the most extreme scenarios the Universe can offer.
	Novel HIV vaccine candidate is safe and induces immune response in healthy adults and monkeys New research published in The Lancet shows that an experimental HIV-1 vaccine regimen is well-tolerated and generated comparable and robust immune responses against HIV in healthy adults and rhesus monkeys. Moreover, the vaccine candidate protected against infection with an HIV-like virus in monkeys.
	Water compresses under a high gradient electric field Modern civilization relies on water's incompressibility—it's something we take for granted. Hydraulic systems harness the virtual non-compressibility of fluids like water or oil to multiply mechanical force. Bulldozers, cranes, and other heavy machinery exploit the physics of hydraulics, as do automobile brakes, fire sprinkler systems, and municipal water and waste systems. It takes extraordinary pressure to compress water. Even at the bottom of the deepest oceans, two and a half miles under the surface, where pressure is equal to about 1000 atmospheres, water is compressed by only 5 percent.
	World's first animals caused global warming The evolution of Earth's first animals more than 500 million years ago caused global warming, new research shows.
	Researchers see beam of light from first confirmed neutron star merger emerge from behind sun A research team led by astronomers at the University of Warwick had to wait over 100 days for the sight of the first of confirmed neutron star merger to remerge from behind the glare of the sun.
	Einstein's theory of gravity holds – even in extreme conditions Drop a marble and a cannon ball off the Leaning Tower of Pisa at the same time and they will hit the ground at the same time. That fact is explained by Albert Einstein's theory of gravity—general relativity—which predicts that all objects fall in the same way, regardless of their mass or composition.
	Fresh grounds for coffee: Study shows it may boost longevity (Update) Go ahead and have that cup of coffee, maybe even several more. New research shows it may boost chances for a longer life, even for those who down at least eight cups daily.
	'Skinny fat' in older adults may predict dementia, Alzheimer's risk A new study has found that "skinny fat—the combination of low muscle mass and strength in the context of high fat mass—may be an important predictor of cognitive performance in older adults. While sarcopenia, the loss of muscle tissue that is part of the natural aging process, as well as obesity both negatively impact overall health and cognitive function, their coexistence poses an even higher threat, surpassing their individual effects.
	Rising sea levels could cost the world $14 trillion a year by 2100 Failure to meet the United Nations' 2ºC warming limits will lead to sea level rise and dire global economic consequences, new research has warned.
	Spiders go ballooning on electric fields The aerodynamic capabilities of spiders have intrigued scientists for hundreds of years. Charles Darwin himself mused over how hundreds of the creatures managed to alight on the Beagle on a calm day out at sea and later take-off from the ship with great speeds on windless day.
	Study suggests dogs have lost ability to reconcile after violent conflicts A team of researchers with the University of Vienna's Messerli Research Institute has found that wolves tend to reconcile shortly after conflicts but dogs do not. In their paper published in the journal Royal Society Open Science, the group describes their study of captive wolf packs and dogs from a rescue shelter and what they learned.
	Game changing invention to revolutionise cybersecurity Cyberattacks may become impossible with the creation of the first practical quantum random number generator.
