1 Were  living  in  an  astonishing  moment  for  science.  Every  day，  countless  breakthroughs， inventions， and discoveries are announced. At this very moment， all around the world， an untold number of scientists are peering into the dark corners of reality to illuminate their secrets.

Scientists built a nano?robot from DNA

2 Understanding whats happening in our bodies is something weve gotten pretty good at. Scientists have constructed a nano?robot made out of DNA which looks like folded paper. The robot is small enough to interact with human cells at a resolution（分辨率） of one piconewton（皮克牛顿）. That level of precise force allows the robot to target specific mechanical receptors（接收器） on the surface of a cell and activate them so scientists can see what theyre up to.

Amyotrophic Lateral Sclerosis （ALS） （肌萎缩性侧索硬化症，渐冻症） patient speaks using a computer?brain interface

3 According to a paper， electrode arrays （电极阵列） were  placed  in  the  patients  brain  and  the  system  was trained to recognize activity in nearby nerves. The patient controlled a computer by activating those nerves， reportedly by trying to move his eye， in order to answer yes or no questions and painstakingly spell out sentences. Theres a long way to go before these interfaces become widely available.

The birth of a gas giant

4 A recent study published in the journal Nature Astronomy took a good hard look at a system called AB Aurigae， 505 light years away from Earth. The star at the center of that system is young， estimated at only 2 million years old and is in its planetary nursery phase. Among the planets forming， there is a gas giant roughly nine times the size of Jupiter which is in the process of forming.

Asteroid impacts create diamond?like materials

5 Diamonds typically form deep beneath Earths surface in an environment with intense heat and pressure， but it turns out that the universe has found more than one way to make them. Asteroid impacts bring heat and pressure in spades， creating conditions that could be ripe for diamond production. An international team of scientists recently published a study which confirms that a 50，000?year?old impactor created novel diamond?like materials when it crash?landed on our planet.
