Gene editing and genetic modification may seem like something from the far-off future, but as it turns out, the future is now. Scientists have proven they can successfully edit the genes of human embryos and eliminate hereditary genetic diseases. It’s the first time this type of experiment has occurred in the United States.
Gamma-ray bursts are the most intense, violent and powerful explosions in our universe, surpassed only by the Big Bang itself. Scientists know they exist; we’ve been tracking them for nearly 50 years. But the specific cause of these intense sources of energy has remained a mystery to us. Now, scientists have used telescopes to capture a gamma-ray burst as it happened, and they may have narrowed down exactly how they work.
You may have heard that earlier this month the Northern Lights, also known as Aurora Borealis, were visible much farther south than usual. That’s because a coronal mass ejection from the Sun hit the Earth’s magnetic field. The phenomenon is connected to a massive "hole" in the Sun that astronomers discovered using NASA’s Solar Dynamics Observatory. The hole, better known as a sunspot, is so large it’s bigger than the Earth itself.
Last month, a group of six teenage Afghan girls made headlines after U.S. officials denied them entry into the country for a robotics competition. It turns out that the group applied for visas a second time — and were once again denied. But there’s some good news: On Wednesday, the decision was reversed, and the Afghan team received permission to enter the United States.
