Year in review: 5. Sea ice loss will shake up ecosystems
In a better world, it would be the big news of the year just to report that Arctic sea ice shrank to 4.14 million square kilometers this summer, well below the 1981–2010 average of 6.22 million square kilometers (SN Online: 9/19/16). But in this world of changing climate, extreme summer ice loss has become almost expected. More novel in 2016 were glimpses of the complex biological consequences of melting at the poles and the opening of Arctic passageways, talked about for at least a decade and now well under way.

Year in review: 4. ‘Three-parent baby’ technique raises hope and concern
A “three-parent baby” was born in April, the world’s first reported birth from a controversial technique designed to prevent mitochondrial diseases from passing from mother to child.
“As far as we can tell, the baby is normal and free of disease,” says Andrew R. La Barbera, chief scientific officer of the American Society for Reproductive Medicine. “This demonstrates that, in point of fact, the procedure works.”

Year in review: 3. A planet lurks around the star next door
Worlds in the Alpha Centauri system — the trio of stars closest to our sun — have been a staple of science fiction for decades. From Star Trek to Avatar, writers have dreamed up exotic landscapes (and inhabitants) for interstellar explorers to encounter. Now a planet around one of those stars is no longer fiction.

Year in review: 2. Zika virus devastates Brazil and spreads fear across Americas
Brazilian mother cradles her baby girl under a bruised purple sky. The baby’s face is scrunched up, mouth open wide — like any other crying child. But her head is smaller than normal, as if her skull has collapsed above her eyebrows.
A week earlier, not far away, a doctor wrapped a measuring tape around the forehead of a 1-month-old boy, held in the arms of his grandmother. This baby too has a shrunken head, a birth defect whose name — microcephaly — has now become seared into the public consciousness.

Year in review: 1. Gravitational waves offer new cosmic views
The secrets gleaned from the universe’s most mysterious giants are incongruously subtle when witnessed at Earth: Detectors budge by a tiny fraction of a proton’s breadth, outputting a feeble, birdlike chirp.
For centuries, astronomers have peered out into the universe almost exclusively by observing its light. But 2016’s announcement of the first detection of gravitational waves, produced 1.3 billion years ago in the collision of two monstrous black holes, has given scientists a whole new way of observing the heavens.

We will soon be able to read minds and share our thoughts
The first true brain-to-brain communication in people could start next year, thanks to huge recent advances.
Early attempts won’t quite resemble telepathy as we often imagine it. Our brains work in unique ways, and the way each of us thinks about a concept is influenced by our experiences and memories. This results in different patterns of brain activity, but if neuroscientists can learn one individual’s patterns, they may be able to trigger certain thoughts in that person’s brain. In theory, they could then use someone else’s brain activity to trigger these thoughts.

Bizarre Antimatter Emits Same Light As Regular Matter
or the first time, physicists have shown that atoms of antimatter appear to give off the same kind of light that atoms of regular matter do when illuminated with lasers, a new study finds.
More precise measurements of this emitted light could unearth clues that might finally help solve the mystery of why there is so much less antimatter than normal matter in the universe, researchers say.

Scientists have used 'pregnancy fluid' to strengthen ageing bones
Researchers have collected stem cells from human amniotic fluid - the protective fluid that surrounds the baby in the uterus - and used them to treat mice with brittle bone disease.
The treatment resulted in 79 percent fewer fractures by actively increasing the strength, plasticity, and structure of the animals’ bones, and now the team is investigating if it will work in humans - particularly astronauts, who can lose 2.5 percent of their bone density for every month in space.

Mystery of 'Alien Megastructure' Star Testing Astronomers' Creativity
Astronomers may have to think a little harder to solve the mystery of Boyajian's star.
Researchers have come up with many possible causes for the dimming, including a swarm of broken-apart comet fragments, variability in the activity of the star itself, a cloud of some sort in the interstellar medium between Kepler and Boyajian's star, and, most famously, an orbiting "megastructure" built by an alien civilization to collect stellar energy.
Researchers are testing these hypotheses to the extent possible. For example, the $100 million Breakthrough Listen initiative is using the Green Bank Telescope in West Virginia to hunt for signals coming from Boyajian's star, which lies about 1,500 light-years from Earth.

China claims it's already started testing an EM Drive in space
Peer review or it didn't happen.
The whole world got excited last month when NASA published the first peer-reviewed paper on the 'impossible' electromagnetic, or EM, Drive, which appears to somehow defy physics by producing thrust without a propellant.
Their verdict was that it seems to work, although a lot of physicists still think the results are flawed. But now researchers in China have announced that they've already been testing the controversial drive in low-Earth orbit, and they're looking into using the EM Drive to power their satellites as soon as possible.
Big disclaimer here - all we have to go on right now is a press conference announcement and an article from a government-sponsored Chinese newspaper (and the country doesn't have the best track record when it comes to trustworthy research).

Cassini’s grand finale will see orbiter plunge into Saturn

6 more mysterious radio signals have been detected coming from outside our galaxy
Back in March, scientists detected 10 powerful bursts of radio signals coming from the same location in space. And now researchers have just picked up six more of the signals seemingly emanating from the same region, far beyond our Milky Way.
These fast radio bursts (FRB) are some of the most elusive and explosive signals ever detected from space - they only last milliseconds, but in that short period of time, they generate as much energy as the Sun in an entire day. But despite how powerful they are, scientists still aren't sure what causes them.
