Presidential Debate: Expert Panel Gives Scientific Analysis of Candidates' Performances

Four expert panelists each day will present their analyses and answer your questions live and face-to-face. This event will be virtual. You can attend with any device -- PC, Mac, iPad, iPhone or Android device (with a webcam) – anywhere with good bandwidth. To participate (ask questions) in the meeting, you must be on video, just as a normal news conference. Register below for guaranteed seating; there is limited seating in the virtual room. Eight experts (four at each event) will present their analyses. The diverse expert team (7 universities and an institute) will analyze both candidates during the debates for their gestures, facial expressions (including smiles--number, type, appropriateness, etc.), posture, language, including sentiment, tone, inflammatory language, repetition, vocabulary, sentence structure, metaphors, framing, themes, suggestions, subtlety, nuance, honesty (deceit/lies—explicit and implicit), transparency, gender issues, and more...

Sleep Paralysis: Fully Awake and Unable to Move

SleepParalysis.jpg

Your eyes begin to open after a good night of sleep, but something feels weird. You try to take a deep breath but can’t draw air. You can’t sit up, and you may even see a shadow in the corner of the room. This isn’t a nightmare or a medical emergency—you likely just had a case of sleep paralysis.

Revealing Earth’s Early Secrets: Scientists Uncover Insights Into the Formation of Earth’s Oldest Continental Crust

P1130482.jpg

Addressing fundamental unknowns about the earliest history of Earth’s crust, scientists have precisely dated the world’s oldest rock unit at 4.02 billion years old. Driven by the University of Alberta, the findings suggest that early Earth was largely covered with an oceanic crust-like surface.

Hubble Takes Close-Up Look at Disintegrating Comet

Astronomers have captured the sharpest, most detailed observations of a comet breaking apart 67 million miles from Earth, using NASA's Hubble Space Telescope. This study of Comet 332P is published online in The Astrophysical Journal Letters.

All Polar Bears Across the Arctic Face Shorter Sea Ice Season

A new University of Washington study finds a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears. The paper is the first to quantify the sea ice changes in each polar bear subpopulation across the entire Arctic region using metrics that are specifically relevant to polar bear biology.

Acetaminophen Not Associated with Worse Asthma in Kids

Children with mild, persistent asthma did not have worse asthma symptoms after taking acetaminophen (e.g., Tylenol) for pain or fever, compared to using ibuprofen (e.g., Advil), according to the results of a randomized, double-blind clinical trial recently published in the New England Journal of Medicine.

Monkeys in Zoos Have Human Gut Bacteria

RedshankeddoucLargephoto.jpg

A new study led by the University of Minnesota shows that monkeys in captivity lose much of their native gut bacteria diversity and their gut bacteria ends up resembling those of humans. The results suggest that switching to a low-fiber, Western diet may have the power to deplete most normal primate gut microbes in favor of a less diverse set of bacteria.

Milky Way Had a Blowout Bash 6 Million Years Ago

122775_web.jpg

The center of the Milky Way galaxy is currently a quiet place where a supermassive black hole slumbers, only occasionally slurping small sips of hydrogen gas. But it wasn't always this way. A new study shows that 6 million years ago, when the first human ancestors known as hominins walked the Earth, our galaxy's core blazed forth furiously. The evidence for this active phase came from a search for the galaxy's missing mass.

Earth-Mass Planet Right Next Door

eso1629a-small.jpg

A potentially habitable planet – Proxima Centauri b – has been found virtually next door to Earth: about four light years away. The Weizmann Institute’s Dr. Aviv Ofir is a member of the “Pale Red Dot” project; the team found that the new planet may have balmy temperatures and liquid water, albeit a fast orbit. Can it host life? Further research is underway.

The Brain Uses Backward Instant Replays to Remember Important Travel Routes

IMG_1925_sq.jpg

Neuroscientists believe they have figured out how rats solve certain navigational problems. If there’s a “reward” at the end of the trip, specialized neurons in the hippocampus of the brain “replay” the route taken to get it, but backward. And the greater the reward, the more often the rats’ brains replay it.
