    One of the well-known challenges of marriage is keeping the passion alive after years of partnership, as passions tend to cool even in very happy relationships. Psychological scientists have now developed an unconventional intervention for helping a marriage maintain its spark: pictures of puppies and…
  2. Fighting global warming and climate change requires a broad energy portfolio

    06.19 / 22:14 sciencedaily.com ScienceDaily - Science
    Can the continental United States make a rapid, reliable and low-cost transition to an energy system that relies almost exclusively on wind, solar and hydroelectric power? While there is growing excitement for this vision, a new study describes a more complicated reality. Researchers argue that achieving net-zero carbon emissions requires the incorporation of a much broader suite of energy sources and…
  3. X-ray eyes in the sky: Drones and WiFi for 3-D through-wall imaging

    06.19 / 20:20 sciencedaily.com ScienceDaily - Science
    Researchers have given the first demonstration of 3-D imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency search-and-rescue, archaeological discovery and structural…
  4. Ancient DNA reveals role of Near East and Egypt in cat domestication

    06.19 / 18:16 sciencedaily.com ScienceDaily - Science
    DNA found at archaeological sites reveals that the origins of our domestic cat are in the Near East and ancient Egypt. Cats were domesticated by the first farmers some 10,000 years ago. They later spread across Europe and other parts of the world via trade hub Egypt. The DNA analysis also revealed that most of these ancient cats had stripes: spotted cats were uncommon until the Middle…
  5. Sound waves direct particles to self-assemble, self-heal

    06.19 / 17:11 sciencedaily.com ScienceDaily - Science
    Scientists have demonstrated how floating particles will assemble and synchronize in response to acoustic waves. Their simple experiment provides a new framework for studying how seemingly lifelike behaviors emerge in response to external forces. The work could help address fundamental questions about energy dissipation and non-equilibrium…
  6. Cells that make blood vessels can also make tumors and enable their spread
