This Wild New Study Says Mars Didn’t Form Where We Thought It Did – Mars and Earth are widely thought to have formed into planets in the same region of the early Solar System, but if that’s the case, why are their compositions so different? A new study might have the answer. Science Alert

In The First Months Of Pregnancy Natural Killer Cells Actually Nurture The Fetus – Natural killer cells are part of the body’s defense system, ruthless destroyers of invading armies of bacteria or viruses. Yet in the first trimester of pregnancy they show another side, gentle and nurturing. Far from attacking the fetus as a foreign object, as the immune system can sometimes do, they ensure it gets the nutrients it needs to grow. The team that discovered this trait have taken the first steps to harnessing it to combat nutrient starvation of the fetus. IFLScience

Could cognitive interventions be useful in treating depression? – A new study has examined whether cognitive bias modification (CBM) for facial interpretation, a digital health intervention that changes our perception for emotional expressions from negative to positive, might be useful in treating depression. Science Daily

Lyme bacteria survive 28-day course of antibiotics months after infection – Lyme bacteria can survive a 28-day course of antibiotic treatment four months following infection by tick bite, according to a new study using a primate model for the disease. Despite testing negative for Lyme disease, some subjects were infected with Lyme bacteria in heart, brain and other organs. Science Daily

To sleep or not: Researchers explore complex genetic network behind sleep duration – Scientists have identified differences in a group of genes they say might help explain why some people need a lot more sleep — and others less — than most. The study, conducted using fruit fly populations bred to model natural variations in human sleep patterns, provides new clues to how genes for sleep duration are linked to a wide variety of biological processes. Science Daily

These weather events turned extreme thanks to human-driven climate change – For the first time, scientists have definitively linked human-caused climate change to extreme weather events. Science News

10 Science News Roundup #12

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

Pancreatic cancer survival linked to four genes – Alterations in four main genes are responsible for how long patients survive with pancreatic cancer, according to a new study in JAMA Oncology. Science Daily

Humans are driving climate change, federal scientists say – It is “extremely likely” that humans are driving warming on Earth since the 1950s. That statement — which indicates a 95 to 100 percent confidence in the finding — came in a report released November 3 by the U.S. Global Change Research Program. This interagency effort was established in 1989 by presidential initiative to help inform national science policy. Science News

Alzheimer’s protein can travel from blood to build up in the brain – An Alzheimer’s-related protein can move from the blood to the brain and accumulate there, experiments on mice show for the first time. Science News

Sleep Deprivation Has The Same Effect as Drinking Too Much, Says Study – A lack of sleep not only causes us to drop off at our desks in the afternoon and feel cranky, it also weakens crucial communications between the neurons in the brain, according to a new study. Science Alert

Scientists Just Confirmed 18 More Possible Habitable Planets – Remember the other day, when we told you that scientists had found some potentially habitable planets hiding in Kepler data? Well, scientists have found 18 more – and they’re just as important. IFLScience

We Think We Know Where That Interstellar Object Came From – We may have spied our first ever interstellar object in the Solar System last month. Now, scientists think they might know where it came from. IFLScience

Mystery void is discovered in the Great Pyramid of Giza – High-energy particles from outer space have helped uncover an enigmatic void deep inside the Great Pyramid of Giza. Science News

The way hungry young stars suck in food keeps most X-rays in, too – A plasma cocoon lets growing stars keep their X-rays to themselves. Laboratory experiments that mimic maturing stars show that streams of plasma splash off a star’s surface, forming a varnish that keeps certain kinds of radiation inside. Science News

Artificial insulin-releasing cells may make it easier to manage diabetes – Artificial cells made from scratch in the lab could one day offer a more effective, patient-friendly diabetes treatment. Science News

Stimulating formation of new neural connections in the adult brain – A team led by University of Idaho scientists has found a way to stimulate formation of new neural connections in the adult brain in a study that could eventually help humans fend off memory loss, brain trauma and other ailments in the central nervous system. Science Daily

10 Science News Roundup #10

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

Scientists Have Concluded That The Universe Shouldn’t Really Exist – Scientists just confirmed the problem at the centre of the Universe: it shouldn’t really exist at all. Science Alert

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.
