Science X Newsletter Week 20

Dear Reader ,

Here is your customized Science X Newsletter for week 20:

	415.26 parts per million: CO2 levels hit historic high Scientists in the United States have detected the highest levels of planet-warming carbon dioxide in Earth's atmosphere since records began, sounding new alarm over the relentless rise of man-made greenhouse gas emissions.
	Groundbreaking genetic discovery shows why Lupus develops In a world first, researchers from The Australian National University (ANU) have shown previously ignored rare genetic mutations are a major cause of lupus.
	Natural compound found in broccoli reawakens the function of potent tumor suppressor Your mother was right: Broccoli is good for you. Long associated with decreased risk of cancer, broccoli and other cruciferous vegetables—the family of plants that also includes cauliflower, cabbage, collard greens, Brussels sprouts and kale—contain a molecule that inactivates a gene known to play a role in a variety of common human cancers. In a new paper published today in Science, researchers, led by Pier Paolo Pandolfi, MD, Ph.D., Director of the Cancer Center and Cancer Research Institute at Beth Israel Deaconess Medical Center, demonstrate that targeting the gene, known as WWP1, with the ingredient found in broccoli suppressed tumor growth in cancer-prone lab animals.
	US journalism has become more subjective: study U.S.-based journalism has gradually shifted away from objective news and offers more opinion-based content that appeals to emotion and relies heavily on argumentation and advocacy, according to a new RAND Corporation report.
	Common food additive E171 found to affect gut microbiota University of Sydney research provides new evidence that nanoparticles, which are present in many food items, may have a substantial and harmful influence on human health.
	It's in the weeds: Herbicide linked to human liver disease Glyphosate, the primary ingredient in Monsanto's popular weed killer Roundup, has been linked to liver disease in animal models. In a new study, the first of its kind, researchers at the University of California San Diego School of Medicine report an association between the herbicide and negative effects upon the human liver.
	Study finds scientific reproducibility does not equate to scientific truth Reproducible scientific results are not always true and true scientific results are not always reproducible, according to a mathematical model produced by University of Idaho researchers. Their study, which simulates the search for that scientific truth, will be published Wednesday, May 15, in the journal PLOS ONE.
	Energy-free superfast computing invented by scientists using light pulses Superfast data processing using light pulses instead of electricity has been created by scientists.
	Researchers shed new light on atomic 'wave function' Physicists have demonstrated a new way to obtain the essential details that describe an isolated quantum system, such as a gas of atoms, through direct observation. The new method gives information about the likelihood of finding atoms at specific locations in the system with unprecedented spatial resolution. With this technique, scientists can obtain details on a scale of tens of nanometers—smaller than the width of a virus.
	China's Chang'E 4 mission discovers new 'secrets' from the far side of the moon A lunar lander named for the Chinese goddess of the moon may have lessened the mystery of the far side of the moon. The fourth Chang'E probe (CE-4) was the first mission to land on the far side of the moon, and it has collected new evidence from the largest crater in the solar system, clarifying how the moon may have evolved. The results were published on May 16, 2019, in Nature.
	Oldest Scandinavian human DNA found in ancient chewing gum The first humans who settled in Scandinavia more than 10,000 years ago left their DNA behind in ancient chewing gum, masticated lumps made from birch bark pitch. This is shown in a new study conducted at Stockholm University and published in Communications Biology.
	Quantum world-first—researchers reveal accuracy of two-qubit calculations in silicon For the first time ever, researchers have measured the fidelity—that is, the accuracy—of two-qubit logic operations in silicon, with highly promising results that will enable scaling up to a full-scale quantum processor.
	Sugary drinks and fruit juice may increase risk of early death (HealthDay)—Most folks know that sugary drinks aren't healthy, but a new study finds fruit juices are not much better.
	NASA dubs 2024 Moon mission 'Artemis,' asks for $1.6 billion NASA's next mission to the Moon will be called Artemis, the US space agency announced Monday, though it's still looking for the money to make the journey happen by its accelerated 2024 deadline.
	New research reveals what was on the menu for medieval peasants Scientists from the University of Bristol have uncovered, for the first time, definitive evidence that determines what types of food medieval peasants ate and how they managed their animals.
	After the Moon, people on Mars by 2033... or 2060 On December 11, 2017, US President Donald Trump signed a directive ordering NASA to prepare to return astronauts to the Moon "followed by human missions to Mars and other destinations."
	First smartphone app that can hear ear infections in children Ear infections are the most common reason that parents bring their children to a pediatrician, according to the National Institutes of Health.
	Neanderthals and modern humans diverged at least 800,000 years ago Neanderthals and modern humans diverged at least 800,000 years ago, substantially earlier than indicated by most DNA-based estimates, according to new research by a UCL academic.
	It's not just fish, plastic pollution harms the bacteria that help us breathe Ten per cent of the oxygen we breathe comes from just one kind of bacteria in the ocean. Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a study published in Communications Biology.
	Generating high-quality single photons for quantum computing MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers.
