  • How well-fed mosquitoes outwit victims at take-off
    on October 18, 2017 at 10:00 pm

    Stealth and haste are often at the heart of most successful raids, and the forays of famished female mosquitoes are no different. "Female mosquitoes need a blood meal to develop their eggs," explains Florian Muijres, from Wageningen University, The Netherlands, adding that zipping in and out after a quick sip without attracting the attention of the unfortunate victim is essential if the insect is to survive.

  • Spinning comet observed to rapidly slow down during close approach to Earth
    on October 18, 2017 at 8:37 pm

    Astronomers at Lowell Observatory observed comet 41P/Tuttle-Giacobini-Kresak last spring and noticed that the speed of its rotation was quickly slowing down. A research team led by David Schleicher studied the comet while it was closer to the Earth than it has ever been since its discovery. The comet rotational period became twice as long, going from 24 to more than 48 hours within six weeks, a far greater change than ever observed before in a comet. If it continues to slow down, it might stop completely and then begin rotating in the opposite direction.  […]

  • A solar-powered asteroid nursery at the orbit of Mars
    on October 18, 2017 at 8:35 pm

    The planet Mars shares its orbit with a handful of small asteroids, the so-called Trojans. Among them, one finds a unique group, all moving in very similar orbits, suggesting that they originated from the same object. But the mechanism that produced this "family" has been a mystery. Now, an international team of astronomers believe they have identified the culprit: sunlight. Their findings, which highlight how small asteroids near the Sun may evolve, are to be presented at the annual Meeting of the Division of Planetary Sciences of the American Astronomical Society at Provo, Utah this week, by Dr. Apostolos Christou, a Research Astronomer at the Armagh Observatory and Planetarium in Northern Ireland, United Kingdom and leader of the research team.

  • Physics boosts artificial intelligence methods
    on October 18, 2017 at 8:18 pm

    Researchers from Caltech and the University of Southern California (USC) report the first application of quantum computing to a physics problem.

  • Riddle of matter remains unsolved: Proton and antiproton share fundamental properties
    on October 18, 2017 at 5:00 pm

    The search goes on. No difference in protons and antiprotons have yet been found which would help to potentially explain the existence of matter in our universe. However, physicists in the BASE collaboration at the CERN research center have been able to measure the magnetic force of antiprotons with almost unbelievable precision. Nevertheless, the data do not provide any information about how matter formed in the early universe as particles and antiparticles would have had to completely destroy one another. The most recent BASE measurements revealed instead a large overlap between protons and antiprotons, thus confirming the Standard Model of particle physics. Around the world, scientists are using a variety of methods to find some difference, regardless of how small. The matter-antimatter imbalance in the universe is one of the hot topics of modern physics. […]
