  • Dynamic pattern of skyrmions observed
    on October 15, 2019 at 4:57 pm

    Cu2OSeO3 is a material with unusual magnetic properties. Magnetic spin vortices known as skyrmions are formed within a certain temperature range when in the presence of a small external magnetic field. Currently, moderately low temperatures of around 60 Kelvin (-213 degrees Celsius) are required to stabilise their phase, but it appears possible to shift this temperature range to room temperature. The exciting thing about skyrmions is that they can be set in motion and controlled very easily, […]

  • Are some urban settings riskier for traffic injury or death? We know less than you think
    on October 15, 2019 at 4:54 pm

    How dangerous is travel in the United States? It depends on how you frame the question. If it's risk per kilometer, the U.S. has 6.71 deaths per billion vehicle kilometers of travel compared to the United Kingdom, which has just 3.56 deaths per billion vehicle kilometers. This makes vehicular travel in the U.S. about 88.6 percent more dangerous than travel in the U.K. If it's risk per year of life, the U.S. has 10.25 deaths per 100,000 people whereas the U.K. has just 2.86—a risk level of […]

  • Did early mammals turn to night life to protect their sperm?
    on October 15, 2019 at 4:49 pm

    Humans are diurnal—we are active in the day and sleep at night. But diurnalism is by far the exception rather the rule in mammals. About 250-230 million years ago, the mammalian ancestors, called the therapsids, became exclusively nocturnal, and stayed so until the demise of the dinosaurs 66 million years ago. All of our mammal ancestors lived in the dark for about 200 years, and the majority still do to this day. Humans are, essentially, nocturnal animals that have reverted back to […]

  • Researchers solve puzzle about link between genetic mutations, mating in fruit flies
    on October 15, 2019 at 4:48 pm

  • Searching for water
    on October 15, 2019 at 4:44 pm

    In a place like Delaware, where it rains frequently, water is a renewable resource. Natural processes will replenish the water that is being used or consumed. In an area where rain is not as plentiful, such as the Arabian Peninsula, however, it is crucial to get a handle on how much good water is available under the arid desert in what are known as fossil aquifers—aquifers that store older water.

  • Integration of refugees: Germans in east and west show similar willingness to help
    on October 15, 2019 at 4:43 pm

    In discussions in Germany on immigrants, particularly eastern Germany is often associated with attacks on foreigners and hate crimes against refugees. Research data and surveys also indicate that prejudices against immigrants are often stronger in the east of the country than in the western half. But are these differences also reflected in small acts of everyday help? This question was looked at in detail by German researchers. They carried out two field studies in which they compared the […]

  • New method for quicker and simpler production of lipidated proteins
    on October 15, 2019 at 3:31 pm

    Some of the body's proteins are not just made up of amino acids, they are also 'decorated' with lipid chains, which significantly influence the biological functions of the protein. An example is the Ras protein, which plays a role in the development of many types of cancers and is only active and cancer-causing if it is able to bind to the cell membrane with the help of a 'lipid anchor.'

  • The brain does not follow the head
    on October 15, 2019 at 4:00 am

    The human brain is about three times the size of the brains of great apes. This has to do, among other things, with the evolution of novel brain structures that enabled complex behaviors such as language and tool production. A study by anthropologists at the University of Zurich now shows that changes in the brain occurred independent of evolutionary rearrangements of the braincase.

  • Tissue damage caused by a heart attack to be reduced by 30%?
    on October 15, 2019 at 4:00 am

    A heart attack is caused by a clot that blocks the artery blood flow. Under these conditions, the affected tissues undergo a rapid necrosis. But why? Scientists (UNIGE, Lyon and Inserm) discovered that the synthesis of a lipid provokes the necrosis. This lipid accumulates in the absence of oxygen and blocks cellular functions. By inhibiting its synthesis in a mouse suffering a heart attack, the biologists were able to reduce the tissue damage by 30%.

  • Quantum physics: Ménage à trois photon-style
    on October 15, 2019 at 4:00 am

    When two photons become entangled, the quantum state of the first will correlate perfectly with the quantum state of the second. Today, researchers (UNIGE and IPM) have proved that 3 pairs of entangled photons allow for a new form of quantum correlation in theory. When the scientists forced 2 photons from separate pairs to become entangled, the connection was also made with their twin photon present elsewhere in the network, forming a highly-correlated triangle.
