Quake, Then Investigate
The recent earthquake in Chile was the fifth largest ever recorded and the U.S. Geological Survey is investigating damaged buildings there to better understand our own California.
The recent earthquake in Chile was the fifth largest ever recorded and the U.S. Geological Survey is investigating damaged buildings there to better understand our own California. "One immediate observation from Chile's earthquake that could find its way into US building code is on confining reinforcement, says Maffei, who is on the committee that decides building code in California. Confining reinforcement is meant to keep vertical bars from bucking, but the design proved insufficient in Chile. Maffei says he would consider requiring confining reinforcement along a greater length of the wall. In preparing an earthquake-proof building code, engineers must also take into account the land the building sits on. Chile provides a case study in this, too. While the center of Santiago withstood the quake relatively well, on the outskirts of the city the metropolitan area of Maipu fared much worse because it sits atop soft volcanic ash, which amplifies the motions of the earthquake. Several apartment complexes in Maipu will have to be demolished."
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
Giving our solar system a "slap in the face."
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
The 116th Congress is set to break records in term of diversity among its lawmakers, though those changes are coming almost entirely from Democrats.
- Women and nonwhite candidates made record gains in the 2018 midterms.
- In total, almost half of the newly elected Congressional representatives are not white men.
- Those changes come almost entirely from Democrats; Republican members-elect are all white men except for one woman.
