Science X Newsletter Week 39

Dear Reader ,

Here is your customized Science X Newsletter for week 39:

	Common weed killer linked to bee deaths The world's most widely used weed killer may also be indirectly killing bees. New research from The University of Texas at Austin shows that honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria.
	People can die from giving up the fight People can die simply because they've given up, life has beaten them and they feel defeat is inescapable, according to new research.
	Rough waters for California's not so public beaches The sandy cove along California's picturesque coast beckons visitors to what is supposed to be a public beach. But the imposing gate, the security guard and the annual $100 access fee tell a different story.
	Molecule capable of halting and reverting neurodegeneration caused by Parkinson's disease identified The small SynuClean-D molecule interrupts the formation of the alpha-synuclein amyloid fibres responsible for the onset of Parkinson's disease, and reverts the neurodegeneration caused by the disease. The study, headed by Universitat Autònoma de Barcelona researchers, was published in PNAS.
	World's first human case of rat disease found in Hong Kong A Hong Kong man has developed the world's first ever human case of the rat version of the hepatitis E virus, according to new research from one of the city's leading universities.
	Scientists discover new mechanism for information storage in one atom Scientists at Radboud University discovered a new mechanism for magnetic storage of information in the smallest unit of matter: a single atom. While the proof of principle was demonstrated at very low temperatures, this mechanism shows promise for room temperature operation. In this way, it will be possible to store a thousands of times more information than in current hard drives. Their findings are published today in Nature Communications.
	Unprecedented study confirms massive scale of lowland Maya civilization Tulane University researchers, documenting the discovery of dozens of ancient cities in northern Guatemala through the use of jungle-penetrating Lidar (light detection and ranging) technology, have published their results in the prestigious journal Science.
	Limiting children's recreational screen time to less than two hours a day linked to better cognition Only one in 20 US children in the study met the full recommended guidelines on recreational screen time, physical activity and sleep.
	Team names world's largest ever bird—Vorombe titan After decades of conflicting evidence and numerous publications, scientists at international conservation charity ZSL's (Zoological Society of London) Institute of Zoology, have finally put the 'world's largest bird' debate to rest. Published today (26 September 2018) in Royal Society Open Science—Vorombe titan (meaning 'big bird' in Malagasy and Greek), has taken the title reaching weights of up to 800 kg and three metres tall, with the research also discovering unexpected diversity in these Madagascan creatures.
	Evidence that addictive behaviors have strong links with ancient retroviral infection New research from an international team led by Oxford University's Department of Zoology and the National-Kapodistrian University of Athens, published today in Proceedings of the National Academy of Sciences (PNAS), shows that an ancient retrovirus—HK2—is more frequently found in drug addicts and thus is significantly associated with addiction.
	3-D bioPen: A hydrogel injection to regenerate cartilage Highly specialized cartilage is characteristically avascular and non-neural in composition with low cell numbers in an aliphatic environment. Despite its apparent simplicity, bioengineering regenerative hyaline cartilage in a form effective for implantation remains challenging in musculoskeletal tissue engineering. Existing surgical techniques including autologous chondrocyte implantation (ACI) and matrix-induced autologous chondrocyte implantation (MACI) are considered superior to self-repair induction techniques. However, both MACI and ACI are complex, multistage procedures that require a double operation; first for surgical excision of native cartilage, followed by expansion of adult chondrocytes in vitro prior to implantation by a second operation.
	Psychologists define the 'dark core of personality' Egoism, Machiavellianism, narcissism, psychopathy, sadism, spitefulness and others are among the traits of the malevolent side of human personality. As results from a recently published German-Danish research project show, these traits share a common "dark core." People with one of these tendencies are also likely to have one or more of the others.
	The warm glow of kindness is real, study confirms Psychologists at the University of Sussex have confirmed that the warm glow of kindness is real, even when there's nothing in it for you. In their study, published in NeuroImage, they undertook a major analysis of existing research showing the brain scans relating to over 1000 people making kind decisions. For the first time, they split the analysis between what happens in the brain when people act out of genuine altruism—where there's nothing in it for them—and when they act with strategic kindness—when there is something to be gained as a consequence.
	Hyper Suprime-Cam survey maps dark matter in the universe Today, an international group of researchers, including Carnegie Mellon University's Rachel Mandelbaum, released the deepest wide field map of the three-dimensional distribution of matter in the universe ever made and increased the precision of constraints for dark energy with the Hyper Suprime-Cam survey (HSC).
	Reclassification recommendations for drug in 'magic mushrooms' In an evaluation of the safety and abuse research on the drug in hallucinogenic mushrooms, Johns Hopkins researchers suggest that if it clears phase III clinical trials, psilocybin should be re-categorized from a schedule I drug—one with no known medical potential—to a schedule IV drug such as prescription sleep aids, but with tighter control.
	Ancient Mars had right conditions for underground life, new research suggests A new study shows evidence that ancient Mars probably had an ample supply of chemical energy for microbes to thrive underground.
	Ice age discovery may reveal early migration route of first Americans A group of researchers have discovered the retreat of an ancient ice sheet from the western coast of Canada occurred earlier than previously thought.
	Ledumahadi mafube—South Africa's new jurassic giant A new species of a giant dinosaur has been found in South Africa's Free State Province. The plant-eating dinosaur, named Ledumahadi mafube, weighed 12 tonnes and stood about four metres high at the hips. Ledumahadi mafube was the largest land animal alive on Earth when it lived, nearly 200 million years ago. It was roughly double the size of a large African elephant.
	Has one of math's greatest mysteries, the Riemann hypothesis, finally been solved? Over the past few days, the mathematics world has been abuzz over the news that Sir Michael Atiyah, the famous Fields Medalist and Abel Prize winner, claims to have solved the Riemann hypothesis.
	Schoolyard tree cover predicts math performance in high-poverty urban schools What if improving academic performance in some of the nation's most disadvantaged and lowest-achieving schools was as easy as planting trees in the schoolyard? It's not that simple, of course, but a new study from the University of Illinois suggests school greening could be part of the solution.
