Science X Newsletter Week 44

Dear Reader ,

Here is your customized Science X Newsletter for week 44:

	Bacterial Fats, not dietary ones, may deserve the blame for heart disease Heart disease and fatty clogs in the arteries go hand in hand. But new evidence suggests the fatty molecules might come not only from what you eat, but from the bacteria in your mouth, report UConn scientists in the 16 August issue of the Journal of Lipid Research. The research may explain why gum disease is associated with heart trouble.
	Your bones affect your appetite—and your metabolism Your skeleton is much more than the structure supporting your muscles and other tissues. It produces hormones, too. And Mathieu Ferron knows a lot about it. The researcher at the Montreal Clinical Research Institute (IRCM) and professor at Université de Montréal's Faculty of Medicine has spent the last decade studying a hormone called osteocalcin. Produced by our bones, osteocalcin affects how we metabolize sugar and fat.
	It's mathematically impossible to beat aging, scientists say Aging is a natural part of life, but that hasn't stopped people from embarking on efforts to stop the process.
	Aliens may be more like us than we think Hollywood films and science fiction literature fuel the belief that aliens are other-worldly, monster-like beings, who are very different to humans. But new research suggests that we could have more in common with our extra-terrestrial neighbours, than initially thought.
	Scientists identify mechanism that helps us inhibit unwanted thoughts Scientists have identified a key chemical within the 'memory' region of the brain that allows us to suppress unwanted thoughts, helping explain why people who suffer from disorders such as anxiety, post-traumatic stress disorder (PTSD), depression, and schizophrenia often experience persistent intrusive thoughts when these circuits go awry.
	Physicists make rapid progress in bounding the speed of gravity (Phys.org)—Recent gravitational wave detections have allowed physicists to confirm with greater and greater precision what Einstein predicted over 100 years ago in the theory of general relativity: that gravity does not act instantaneously as Newton thought, but instead propagates at the speed of light.
	Scientists discover hidden chamber in Egypt's Great Pyramid Scientists say they have found a hidden chamber in Egypt's Great Pyramid of Giza, in what would be the first such discovery in the structure since the 19th century and one likely to spark a new surge of interest in the pharaohs.
	Researchers design synthetic beta cells to secrete insulin in response to high blood sugar Treating type 1 diabetes and some cases of type 2 diabetes has long required painful and frequent insulin injections or a mechanical insulin pump for insulin infusion. But researchers from the University of North Carolina and NC State have now developed what could be a much more patient-friendly option: artificial cells that automatically release insulin into the bloodstream when glucose levels rise.
	Neutron star merger confirms decades of predictions On Aug. 17, the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the fifth fingerprint of a massive disturbance in spacetime since LIGO began operations in September 2015. Unlike the first four sets of ripples, which reflected collisions between two black holes, the shape of these spacetime distortions suggested a collision between two neutron stars.
	System for performing 'tensor algebra' offers 100-fold speedups over previous software packages We live in the age of big data, but most of that data is "sparse." Imagine, for instance, a massive table that mapped all of Amazon's customers against all of its products, with a "1" for each product a given customer bought and a "0" otherwise. The table would be mostly zeroes.
	Solar greenhouses generate electricity and grow crops at the same time The first crops of tomatoes and cucumbers grown inside electricity-generating solar greenhouses were as healthy as those raised in conventional greenhouses, signaling that "smart" greenhouses hold great promise for dual-use farming and renewable electricity production.
	Promise seen in possible treatment for autism spectrum disorder Human chromosome 16p11.2 deletion syndrome is caused by the absence of about 27 genes on chromosome 16. This deletion is characterized by intellectual disability; impaired language, communication, and socialization skills; and autism spectrum disorder or ASD.
	Anthropologist group suggests first humans to the Americas arrived via the kelp highway (Phys.org)—A team of anthropologists from several institutions in the U.S. has offered a Perspective piece in the journal Science outlining current theories regarding the first humans to populate the Americas. In their paper, they scrap the conventional view that Clovis people making their way across a Bering land bridge were the first to arrive in the Americas—more recent evidence suggests others arrived far earlier, likely using boats to travel just offshore.
	Alzheimer's disease might be a 'whole body' problem Alzheimer's disease, the leading cause of dementia, has long been assumed to originate in the brain. But research from the University of British Columbia and Chinese scientists indicates that it could be triggered by breakdowns elsewhere in the body.
	Fluidic transistor ushers the age of liquid computers Transistors, those tiny electrical switches that process signals and data, are the brain power behind every electronic device – from laptops and smartphones to your digital thermostat. As they continue to shrink in size, computers have become smaller, more powerful, and more pervasive. However, as we look to build squishy, human-friendly machines that have the look and feel of soft natural organisms, we need to look beyond the rigid materials used to create electrical switches and circuits.
	Strength exercise as vital as aerobic, new research finds Push ups and sit ups could add years to your life according to a new study of over 80,000 adults led by the University of Sydney.
	Egypt archaeologist criticises pyramid void 'discovery' An Egyptian archaeologist overseeing a project to scan a pyramid for voids on Saturday criticised the announcement of a discovery of a passenger plane-sized cavity in the Great Pyramid.
	Cancer cells destroyed with metal from the asteroid that killed the dinosaurs Cancer cells can be targeted and destroyed with the metal from the asteroid that caused the extinction of the dinosaurs, according to new research by an international collaboration between the University of Warwick and Sun Yat-Sen University in China.
	Oldest recorded solar eclipse helps date the Egyptian pharaohs Researchers have pinpointed the date of what could be the oldest solar eclipse yet recorded. The event, which occurred on 30 October 1207 BC, is mentioned in the Bible, and could have consequences for the chronology of the ancient world.
	Colon cancer breakthrough could lead to prevention – and the foods that can help Colon cancer, Crohn's, and other diseases of the gut could be better treated – or even prevented – thanks to a new link between inflammation and a common cellular process, established by the University of Warwick.
