10 Science News Roundup #17

Here are 10 science news that I find very interesting. They cover topics that I care about.

Life’s building blocks observed in spacelike environment – Where do the molecules required for life originate? It may be that small organic molecules first appeared on earth and were later combined into larger molecules, such as proteins and carbohydrates. But a second possibility is that they originated in space, possibly within our solar system. A new study, published this week in the Journal of Chemical Physics, from AIP Publishing, shows that a number of small organic molecules can form in a cold, spacelike environment full of radiation.

3-D printed microfibers could provide structure for artificially grown body parts – Much as a frame provides structural support for a house and the chassis provides strength and shape for a car, a team of engineers believes they have a way to create the structural framework for growing living tissue using an off-the-shelf 3-D printer. Science Daily

Jupiter’s massive Great Red Spot is at least 350 kilometers deep – Jupiter’s Great Red Spot has deep roots. Data from the first pass of NASA’s Juno spacecraft over the incessant storm show that its clouds stretch at least 350 kilometers down into the planet’s atmosphere. That means the storm is about as deep as the International Space Station is high above the Earth. Science News

AI eavesdrops on dolphins and discovers six unknown click types – A new computer program has an ear for dolphin chatter. Science News

Scientists Are Investigating Whether Or Not An Alien Probe Just Passed Us By – Sometimes in science, you have to chase the longshots and take a chance on something so unlikely it feels silly to invest in it, because the payoff would be so huge if it worked. This is why the Robert C. Byrd Green Bank Telescope will be spending time examining the first known interstellar visitor to the Solar System, just in case it is an alien spacecraft. IFLScience

New Nanoparticle Technology Detects Cancer Sooner – In what scientists are calling an exciting advancement in cancer technology research, a team from Rutgers University have invented a cutting-edge method to detect and track cancerous tumors sooner than existing technologies. IFLScience

Here are 10 science news that I find interesting and important to take note.

Beating heart patch is large enough to repair the human heart – Biomedical engineers at Duke University have created a fully functioning artificial human heart muscle large enough to patch over damage typically seen in patients who have suffered a heart attack. The advance takes a major step toward the end goal of repairing dead heart muscle in human patients. Science Daily

Three to four cups of coffee a day linked to longer life – Drinking coffee is “more likely to benefit health than to harm it” for a range of health outcomes, say researchers in The BMJ today. Science Daily

‘Arrow of time’ reversed in quantum experiment – Your lukewarm cup of coffee won’t suddenly heat itself up, no matter how long you put off the trek to the microwave. But the same rule doesn’t necessarily apply to quantum systems. Like chilly air warming a mug, heat can spontaneously flow from a cold quantum particle to a hotter one under certain conditions, researchers report November 10 at arXiv.org. This phenomenon seems to reverse the “arrow of time,” the idea that natural processes run forward but not in reverse (SN: 7/25/15, p. 15). Science News

Republicans Want To Force The Critically Endangered Red Wolf Into Extinction – The red wolf, Canis rufus, currently exists only as a small population in one part of North Carolina. It’s listed under the International Union for Conservation of Nature (IUCN) as critically endangered, which means it’s one step away from being extinct in the wild. IFLScience

The Once-Deadly Scarlet Fever Is Making a Weird Comeback Around The World – After decades of decline, scarlet fever is once again on the rise in the UK and other places around the world, and doctors are scrambling to figure out why. Science Alert

Latest DNA Analysis Shows The Yeti Are Actually Just a Bunch of Bears – The Yeti of the mountains of Asia, hairy like a white ape, yet bipedal and standing taller than a man, is numbered among the world’s most beloved cryptids. Yet, for all the eyewitness accounts, physical evidence of the beast is proving tricky to pin down. Science Alert

The key to breaking down plastic may be in caterpillars’ guts – To destroy plastic, caterpillars go with their gut bacteria. Science News

Common cold viruses reveal one of their strengths – Common cold season is back, which has people wondering why we catch the same virus, year after year. Why don’t we ever develop immunity against the common cold? Professor Pierre Talbot at INRS has known about the incredible variability of coronaviruses for some time. They’re responsible for the common cold as well as many other infections, including neurological diseases. Along with his research associate Marc Desforges, Professor Talbot worked on a study recently published in Nature Communications about the ways in which coronaviruses adapt and evolve, becoming ever more effective at infecting hosts without being defeated by the immune system. Science Daily

Research Shows That Earthworms Can Thrive Even in Mars Soil – Good news, aspiring Martian farmers! The soil composition of Mars oughtn’t hinder earthworm reproduction, if experiments here on Earth are any indication. Science Alert

Powerful new cancer drugs are saving lives, but can also ignite diabetes or other autoimmune conditions – Last week, Yale University immunologist Kevan Herold spoke about a few of his newest diabetes patients to an unlikely audience: oncologists and cancer researchers. At the Society for Immunotherapy of Cancer’s annual meeting in Oxon Hill, Maryland, Herold and other speakers described how a novel class of promising cancer drugs is causing type 1 diabetes and other autoimmune diseases in some of those treated.

Here are 10 science news that I find interesting and important to take note.

Daydreaming is good: It means you’re smart – A new study from the Georgia Institute of Technology suggests that daydreaming during meetings isn’t necessarily a bad thing. It might be a sign that you’re really smart and creative. Science Daily

Transparent solar technology represents ‘wave of the future’ – See-through solar materials that can be applied to windows represent a massive source of untapped energy and could harvest as much power as bigger, bulkier rooftop solar units, scientists report in Nature Energy. Science Daily

Arsenic can cause cancer decades after exposure ends – A new paper published in the Journal of the National Cancer Institute shows that arsenic in drinking water may have one of the longest dormancy periods of any carcinogen. By tracking the mortality rates of people exposed to arsenic-contaminated drinking water in a region in Chile, the researchers provide evidence of increases in lung, bladder, and kidney cancer even 40 years after high arsenic exposures ended. Science Daily

What detecting gravitational waves means for the expansion of the universe – Ripples in spacetime travel at the speed of light. That fact, confirmed by the recent detection of a pair of colliding stellar corpses, kills a whole category of theories that mess with the laws of gravity to explain why the universe is expanding as fast as it is. Science News

Nicaragua Joins Paris Agreement Leaving America And Syria Isolated – The world reeled when President Trump announced that America would withdraw from the Paris climate change agreement earlier this year. Despite all the political, environmental, societal, and economic costs of doing so, the White House declared that it would stop all efforts to combat climate change at a federal level. IFLScience

12 Global Cities Unite In Bold Declaration To Make Streets Fossil Fuel-Free By 2030 – The mayors of London, Los Angeles, Paris, Copenhagen, Barcelona, Quito, Vancouver, Mexico City, Milan, Seattle, Auckland, and Cape Town have just committed to a bold plan to clean up their cities’ air and calm the wider threat of climate change. IFLScience

Why haven’t we had alien contact? Blame icy ocean worlds – Might ET be buried under too much ice to phone Earth? That’s what planetary scientist Alan Stern of the Southwest Research Institute in Boulder, Colorado, has concluded may be delaying our contact with alien civilizations. Most extraterrestrial creatures are likely deep inside their home planets, in subsurface oceans crusted over in frozen water ice, according to a new proposal at this year’s American Astronomy Society Division for Planetary Sciences meeting in Provo, Utah. The hypothesis could explain the lack of signals from other technologically advanced civilizations, a conundrum known as the Fermi paradox. Science

Sun’s light touch explains asteroids flying in formation behind Mars – The power of sunlight appears to be simultaneously creating and destroying families of asteroids, according to a new study of Mars’s Trojans, asteroids that accompany the planet like planes flying in formation. The result, reported yesterday at the American Astronomical Society’s Division for Planetary Sciences meeting in Provo, Utah, solves a minor mystery and could explain the creation of asteroid families in other parts of the solar system. Science

Mating with Neandertals reintroduced ‘lost’ DNA into modern humans – Interbreeding with Neandertals restored some genetic heirlooms that modern humans left behind in the ancient exodus from Africa, new research suggests. Science News

10 Science News Roundup #9

Here are 10 science news that I find interesting and important to take note.

What training exercise boosts brain power best? New research finds out – One of the two brain-training methods most scientists use in research is significantly better in improving memory and attention, Johns Hopkins University researchers found. It also results in more significant changes in brain activity. Science Daily

Brain waves reflect different types of learning – Figuring out how to pedal a bike and memorizing the rules of chess require two different types of learning, and now for the first time, researchers have been able to distinguish each type of learning by the brain-wave patterns it produces. Science Daily

A universal flu shot may be nearing reality – One of the planet’s deadliest viruses makes an annual pass through the United States with little fanfare. It rarely generates flashy headlines or news footage of health workers in hazmat suits. There’s no sudden panic when a sick person shows up coughing and feverish in an emergency room. Yet before next spring, this season’s lethal germ will probably have infected millions of Americans, killing tens of thousands. Still, it’s often referred to as just the flu. Science News

Your eyes make waste. Without it, you could go blind – One man’s trash is another man’s treasure, even at the level of the cell. That’s where—according to new research—a waste product of the retina fuels part of the eye that powers the rods and cones that help us sense light. Without this waste, that part of the eye “steals” glucose from the retina, leading to the death of retinal cells and likely vision loss. The finding could help explain why eyesight degenerates with age—and in diseases such as macular degeneration and diabetes. Science

Was this ancient person from China the offspring of modern humans and Neandertals? – When scientists excavated a 40,000-year-old skeleton in China in 2003, they thought they had discovered the offspring of a Neandertal and a modern human. But ancient DNA now reveals that the “Tianyuan Man” has only traces of Neandertal DNA and none detectable from another type of extinct human known as a Denisovan. Instead, he was a full-fledged member of our species, Homo sapiens, and a distant relative of people who today live in East Asia and South America. The work could help scientists retrace some of the earliest steps of human migration. Science

Blood Transfusions From Some Women Can Be More Dangerous For Men, Says Study – Providing a detailed medical history when donating blood could be more important than we know – and not just when it comes to screening for disease. Science Alert

An Alzheimer’s Drug Has Been Found to Help Teeth Repair Themselves in Just 6 Weeks – Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib. Developed for and trialled to treat Alzheimer’s disease, the drug also happens to promote the natural tooth regrowth mechanism in mice, allowing the tooth to repair cavities. Science Alert

In many places around the world, obesity in kids is on the rise – Over the last 40 years, the number of kids and teens with obesity has skyrocketed worldwide. In 1975, an estimated 5 million girls and 6 million boys were obese. By 2016, those numbers had risen to an estimated 50 million girls and 74 million boys, according to a report published online October 10 in the Lancet. While the increase in childhood obesity has slowed or leveled off in many high-income countries, it continues to grow in other parts of the world, especially in Asia. Science News

Having A High IQ Puts You More At Risk Of Mental Illness, Study Finds – If you look at television shows featuring a genius you very quickly see a pattern emerge. Hugh Laurie’s TV-doctor, House, is a medical genius but struggles with severe depression as well as a messiah complex. Sherlock Holmes can solve any case, but has many addictions and may just be a sociopath. Countless TV shows, films, and books all peddle the idea that highly intelligent people are prone to mental illness. IFLScience

Nine Year Study Finally Explains The Relationship Between Sugar And Cancer – Scientists have discovered the exact relationship between sugar and cancer by revealing that the way in which cancer cells break down sugar is linked to the stimulation of tumor growth. Cancer cells tend to produce energy differently from normal cells – they use a process that involves fermentation of glucose into lactate, rather than ordinary respiration. IFLScience
