    Bacteria In Worms Make A Mosquito Repellent That Might Beat DEET

    The next great insect repellent might come from a strain of bacteria that lives inside a common parasitic worm. A study published Wednesday in Science Advances has found that a compound derived from these bacteria is three times more potent than DEET in repelling mosquitoes. More research must be done to demonstrate its safety, but this bacterial chemical could play an important role in the fight against mosquito-borne illness.

    A cosmic flare called the ‘Cow’ may reveal a new way that stars die

    Astronomers may have discovered a new way that stars can die. A mysteriously brief and bright burst whimsically called the “Cow” reveals an entirely new type of stellar death. The details of that stellar doom, however, remain hazy. Scientists are still debating whether the flare-up, spotted on June 16, 2018, was from an unusual type of star that was eaten by a black hole, or from an old, massive star exploding in a weird sort of supernova.

    Hottest exoplanet ever discovered has metallic skies, rain like lava

    One day in the distant future, a team of intrepid humans might board a starship and set out for a world beyond our solar system — maybe one of the exoplanets of Alpha Centauri, the nearby star system. One place we'll never set foot on is Kelt-9b. In addition to being a gas giant without a solid surface, Kelt-9b lies hundreds of light-years away and is the hottest planet ever observed. Temperatures on its outer layer can exceed 4,000 degrees Celsius (7,000 degrees Fahrenheit) — hotter than some stars — and a new study shows that its superheated atmosphere contains vaporized heavy metals.

    Pancreatic Cancer Immune Checkpoint Target Identified

    While current immune checkpoint inhibitor therapies are largely ineffective against pancreatic cancer, scientists in the U.S. have now identified an immune checkpoint molecule that could represent a promising immunotherapeutic target for this tumor type. The University of Texas MD Anderson Cancer Center-led team found that V-domain immunoglobulin suppressor of T cell activation (VISTA) is preferentially expressed at high levels in pancreatic cancer, when compared with melanoma tumors.

    System has four stars and a planet-forming disk oriented vertically

    Models and observations indicate that both stars and planets form as a cloud of material collapses into a disk. If the process proceeds in an orderly manner, then the planets will all form from the same disk and thus orbit in the same plane. And—because material from the same disk will fall into the star, bringing its momentum with it—the star will rotate with its equator along the same plane. That should lead to a tidy system with the equator of the star lined up with the plane of any planets orbiting it.

Researchers announced this week (January 9, 2019) at the 233rd meeting of the American Astronomical Society in Seattle, Washington, that they’ve discovered the brightest quasar yet known, detected from the period when the universe was just beginning to make luminous objects, such as stars and galaxies.

    Life might exist on the new planet discovered around Barnard's star

    Late last year, astronomers announced that they’d found a super-Earth around Barnard’s star – one of the closest suns to our own. The discovery of a planet just six light-years away was enough to excite astronomers and the public alike. However, the researchers who found the planet said that they suspected the icy world couldn’t support life. But now, a group of astronomers are saying such pessimism may be premature. On Earth, geothermal vents produce heat and create unique environments where life thrives in places otherwise difficult to eke out a living – like the frigid, dark deep of the oceans.

    Scientists Hack A shortcut for Photorespiration in plants, Boosting Crop Growth by 40 percent

    Increasing the yield of crop plants is a major facet of increasing food security, and one way to do this is from understanding plant biology which begins with the process of photosynthesis. Photosynthesis, popularly termed as the “green engine of the earth”, is the process by which plants convert light energy into chemical energy that is later released to fuel the plant activities such as growth. If we want to keep the planet and its growing population running in a sustainable way, we will need plants to produce far more food, energy and applicable biomass than they do today.

    Astronomers have discovered a planet twice the size of Earth, and it's within a zone that could allow liquid water to exist on its surface. The finding comes from data from NASA's Kepler space telescope, which ran out of fuel in October 2018. K2-288Bb, as the new planet is called, is located within its star's habitable zone, which is why liquid water is a possibility.

    Scientists might have seen a black hole being born for the first time ever. A mysterious bright object that lit up the night sky could have been a black hole or neutron star at the moment of its creation, researchers say. The bright glow – spotted from Earth, 200 million light years away – appears to have been the debris of a bright star being swirled around the edge of a black hole. Scientists have been puzzled by the spectacularly bright anomaly spotted deep in space since it was spotted last June.

Our new study published in the American Journal of Human Genetics has shown that erectile dysfunction (ED) has a genetic component.

After the treatment, patients are vulnerable to infection and fatigue until new blood cells grow back. MIT researchers have now devised a way to help blood cells regenerate faster. Their method involves stimulating a particular type of stem cell to secrete growth factors that help precursor cells differentiate into mature blood cells.

    Lab-Grown Mini Kidneys 'Go Rogue,' Sprout Brain and Muscle Cells

    Miniature lab-grown kidneys have been hiding something from the scientists who grew them. Instead of developing into different varieties of kidney cells, some of the cells took a different path and became brain and muscle cells. These simple mini kidneys — also known as kidney organoids — are grown from stem cells that are encouraged to develop into clusters of specific kidney cells. But it turns out that the "recipes" that encourage the development of specialized kidney cells were also cranking out cells from other organs, according to a new study.

    Scientists at Dalhousie Universityhave discovered a new branch on the ‘Tree of Life’ that no one knew existed. Their findings were published today in the journal Nature and will be critical to better understanding the evolutionary history of life on earth. “This discovery literally redraws our branch of the ‘Tree of Life’ at one of its deepest points,” explains Alastair Simpson, the lead author of the study and biology professor at Dalhousie. “It opens a new door to understanding the evolution of complex cells—and their ancient origins—back well before animals and plants emerged on Earth.”
