10 Science News Roundup #8

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

How fever in early pregnancy causes heart, facial birth defects – Duke researchers now have evidence indicating that the fever itself, not its root source, is what interferes with the development of the heart and jaw during the first three to eight weeks of pregnancy. Science Daily

When the brain’s wiring breaks – Among all the bad things that can happen to the brain when it is severely jolted — in a car accident, for example — one of the most common and worrisome is axon damage. Axons are the long stalks that grow out of the bodies of neurons and carry signals to other neurons. They are part of the brain’s “wiring,” and they sometimes grow to amazing lengths — from the brain all the way down to the spinal cord. But axons are thin and fragile. When the brain receives a strong blow, axons are often stressed past their structural limits. They either break or swiftly degenerate. Science Daily

Superbugs may meet their match in these nanoparticles – Antibiotics may have a new teammate in the fight against drug-resistant infections. Researchers have engineered nanoparticles to produce chemicals that render bacteria more vulnerable to antibiotics. These quantum dots, described online October 4 in Science Advances, could help combat pathogens that have developed resistance to antibiotics (SN: 10/15/16, p. 11).

Secret Supereruption That Once Changed The World Found In North America – Yellowstone’s supervolcano gets all the attention these days, but it’s not the only vessel of apocalyptic eruptions. Today, there are several spots around the world that could bring about a game-changing eruption, and volcanologists are always on the hunt for ancient ones that until now have slipped beneath the radar.

Turns Out The Great Barrier Reef Can Actually Heal Itself, But We Have to Help It – he Great Barrier Reef is suffering from recent unprecedented coral bleaching events. But the answer to part of its recovery could lie in the reef itself, with a little help. In our recent article published in Nature Ecology & Evolution, we argue that at least two potential interventions show promise as means to boost climate resilience and tolerance in the reef’s corals: assisted gene flow and assisted evolution.

Bright light therapy at midday helped patients with bipolar depression – Daily exposure to bright white light at midday significantly decreased symptoms of depression and increased functioning in people with bipolar disorder, a recent Northwestern Medicine study found. Science Daily

NASA Is Running Out of The Most Precious Ingredient Needed For Future Space Missions – Classroom models lie – our Solar System isn’t a bunch of bright, closely nestled orbs. Instead, other planets are separated from Earth by unfathomable distances – and are often too cold, dim, and remote for any spacecraft to explore on solar power alone. Science Alert

EPA Says “The War on Coal Is Over” in Major Reversal of Obama’s Clean Power Plan – The Trump administration has formally announced its plan to repeal the Clean Power Plan – President Obama’s key policy to cut greenhouse gas emissions produced by power plants. Science Alert

This Is How Online Dating Has Changed The Very Fabric of Society – Digital match-making services have done more than just change how we find our perfect squeeze; they’re changing the fundamental nature of our social networks. According to a pair of researchers investigating online dating, the way we’re looking for love (and lust) is connecting communities in completely novel ways, breaking down boundaries and possibly even making for stronger long-term relationships. Science Alert

How to make the cosmic web give up the matter it’s hiding – Evidence is piling up that much of the universe’s missing matter is lurking along the strands of a vast cosmic web. A pair of papers report some of the best signs yet of hot gas in the spaces between galaxy clusters, possibly enough to represent the half of all ordinary matter previously unaccounted for. Previous studies have hinted at this missing matter, but a new search technique is helping to fill in the gaps in the cosmic census where other efforts fell short. The papers were published online at arXiv.org on September 15 and September 29. Science News
