• The First CubeSats Ever to Visit Mars Have Gone Silent

  06-02-2019 23:00 via feedproxy.google.com
  When NASA's InSight mission reached Mars last year, it wasn’t alone. It was accompanied by two tiny satellites called CubeSats, or in this case, MarCO, for Mars Cube One. They were the first CubeSats ever to visit the Red Planet. The pair, nicknamed EVE and WALL-E, after Pixar’s fictional robots, relayed information from InSight’s descent. But their real mission was simply to show off their abilities so far from home and prove that such small missions – the total MarCO pr

• Deaf Infants Already Process Information Differently

  06-02-2019 22:50 via feedproxy.google.com
  Babies, many people agree, are pretty interesting. Not because of their personalities (although, to be sure, some babies are great wits), but because of everything going on in their little baby brains. The complex and intricate processing power of an adult brain is literally taking shape within a newborn’s head, as experiences and sensory input forge new neural connections. And if a baby is missing one of those senses — say, hearing — it’s reasonable to think her brain wo

• Silent Neurons: The Dark Matter of the Brain?

  06-02-2019 22:38 via feedproxy.google.com
  Now here's a paper with an interesting title: The dark matter of the brainAuthor Saak V. Ovsepian argues that "the great majority of nerve cells in the intact brain do not fire action potentials, i.e., are permanently silent." This is a remarkable claim, and it raises the question of what these silent neurons are doing. However, I didn't find myself convinced of the existence of this 'dark matter'.Ovsepian points out that numerous studies have found that only a minority of the neuron

• Melting Ice Sheets Will Really Mess With a Fundamental Ocean Current

  06-02-2019 22:30 via feedproxy.google.com
  Researchers have updated their predictions for what melting ice sheets will do to the planet within the next century. By 2100, the shrinking Antarctic and Greenland ice sheets will raise sea levels by nearly 10 inches. The influx of water will disrupt an ocean current vital to our weather, with dangerous consequences.“We’re dealing with a very delicately balanced system,” said Nicholas Golledge, a climate scientist at the Victoria University of Wellington in New Zealand, w

• Women’s Brains Are Younger Than Men’s of the Same Age, Study Finds

  06-02-2019 20:05 via feedproxy.google.com
  Scientists have found an odd difference between the brains of men and women. Women’s brains appear younger than their age, but men’s brains appear to be older.
  When looking at the brains of both sexes of the same chronological age, women’s brains were 3.8 years younger and men's brains were 2.4 years older on average. The finding, published online in the Proceedings of the National Academies of Science, may explain why older women tend to outperform their male pe

• With ALMA, Astronomers Find A Bounty of Organic Molecules Near a Young Star

  One of the fundamental questions in looking for life in the universe is figuring out where the materials necessary for making life are likely to exist. These complex organic molecules are, somewhat surprisingly, found all over: in giant dust clouds in space, and on lonely comets in our own solar system. The question for astronomers is figuring out how they make their way onto planets like Earth.Astronomers looking to learn about the solar system's early history often turn to comets, as t

• Astronomers Map a Black Hole Using 'Echoes' of Light

  Black holes pepper our universe, but like their name implies, most are invisible — until something happens to change that. That something is often material flowing into the black hole. And in March 2018, one such previously invisible black hole flared to life when a flood of matter fell inward, allowing astronomers to spot and track the event, ultimately mapping out the region close to a black hole in finer detail than ever before.That work, published January 9 in Nature, was led b
