    The human genome takes shape and shifts over time

    If you could unravel all the DNA in a single human cell and stretch it out, you’d have a molecular ribbon about 2 meters long and 2 nanometers across. Now imagine packing it all back into the cell’s nucleus, a container only 5 to 10 micrometers wide. That would be like taking a telephone cord that runs from Manhattan to San Francisco and cramming it into a two-story suburban house.

    A bot, not a Kardashian, probably wrote that e-cig tweet

    This just in: Companies use social media to encourage you to buy their products.

    A recent and much-discussed example of such marketing involved pregnant reality television star Kim Kardashian, who was paid to publicly praise the morning sickness drug Diclegis. FDA regulations...

    Five reasons to not totally panic about ticks and Lyme disease

    I thought it was just a scab.

    The brown speck clinging to my baby’s cheek had been there for a day or so, resting on a reddish patch of skin. He must have scratched himself, I thought, as I picked lightly at the mark.

    My husband was the first to figure out the truth. That little round speck wasn’t a scab at all — it was a tick.

    I had recently read a scary article about ticks...

    A few key signs betray betrayal

    Whether it’s Katy Perry poaching dancers from once-BFF Taylor Swift or Clytemnestra orchestrating the murder of her husband Agamemnon, betrayal is a dark, persistent part of the human condition. Unlike garden-variety deception, betrayal happens in established relationships, destroying trust that has developed over time. It’s usually unexpected, and it yields a unique, often irreparable, wound...

    The weekly grind of social jetlag could be a weighty issue

    For some of us, a weekly case of the Mondays isn’t just because of traffic, work pileups or our soulless office space. It’s because we had to get up early, and sleeping in on the weekend was so incredibly glorious. Besides, because we slept in on Sunday, we didn’t get to the gym until the afternoon, we cooked a late dinner for a friend and then we couldn’t fall asleep at all and so stayed up...

    Mission to Pluto: Live coverage

    The New Horizons spacecraft flew by Pluto at 7:49 a.m. EDT on July 14, 2015. Astronomy writer Christopher Crockett wrote several updates from mission control at the Johns Hopkins University Applied Physics Lab in Laurel, Md., from July 12-15, and reviewed some of the mission's major milestones from the last several months. Check our...

    Shifted waking hours may pave the way to shifting metabolism

    Shift work can be brutal. Working late nights, early mornings and constantly changing hours wreaks havoc on social and family life. But in our racing, 24-hour world, someone needs to keep the lights on. For years, scientists have studied just what happens when we play fast and loose with the body’s clock. A handful of new studies add to the evidence that shift work and other kinds of circadian...

    A brief history of timekeeping

    For millennia, humans have harnessed the power of clocks to schedule prayers, guide ocean voyages and, lately, to chart the universe. Whatever their use, all clocks need two basic components: a constant repetitive action (like a pendulum’s swing or an atom’s vibrations) and a way to mark time’s progression.

    Pluto: A timeline of 85 years of discovery

    Clyde Tombaugh began searching for a ninth planet in 1929 and stumbled upon Pluto the following year. In the decades since, our view of Pluto hasn’t changed much. All of that changes on July 14 when the New Horizons spacecraft, nearly 5 billion kilometers from home, slipped past Pluto and gave humankind its only look at this icy world (see "...

    Pluto is only a ‘day’ away

    The New Horizons spacecraft will buzz Pluto and its moons in just one day — one Pluto day, that is. The icy world rotates once for every 6 days, 9 hours and 22 minutes on Earth. Starting at 10:28 p.m. Eastern July 7, Pluto will spin around just one more time before New Horizons makes its closest approach on July 14.

    The probe officially...
