British physicist Stephen Hawking died at the age of 76. He was known as one of the world’s greatest minds. Here are just some of his biggest contributions to the science community.
Stephen Hawking died Wednesday after complications due to amyotrophic lateral sclerosis, a progressive neurodegenerative disease. He was 76.
The world-renowned theoretical physicist and cosmologist was best known for his work on black holes. Hawking theorized that, contrary to the prevailing scientific belief that black holes were inescapable for all forms of matter and energy, they actually emitted a form of radiation ― now known as Hawking radiation. He also played a key role in the mathematical effort to unify Einstein’s general theory of relativity with the emergent field of quantum physics.
Hawking used his position as one of the world’s most famous scientists as a platform to discuss a wide range of issues, from the existence of extraterrestrial life to the nature of philosophy. He skyrocketed to public prominence in 1988, when he published his first general-audience book, A Brief History of Time: From the Big Bang to Black Holes. The cosmology treatise has sold approximately 10 million copies worldwide, making it one of the best-selling science books of all time.
In 1963, when he was just 21 years old, Hawking was famously diagnosed with the debilitating motor neuron disease amyotrophic lateral sclerosis. Though 80 percent of those with ALS die within five years of diagnosis, and Hawking’s own doctors gave him roughly two years to live, he survived for decades, perhaps longer than any other patient with the disease in medical history. Hawking used a wheelchair to move around and a sophisticated computer system to speak for much of his time as a public figure.

SpaceX’s Falcon Heavy rocket successfully completed its long-awaited maiden flight on Tuesday, roaring into the blue skies over Kennedy Space Center to usher in a new era of spaceflight.
The gigantic booster, which lifted off at 3:45 p.m. ET, could one day take astronauts to the moon and Mars. The rocket rose over the Atlantic Ocean before its two expended solid rocket boosters fell back to Earth and landed upright, just as planned. The third booster failed to make a landing on a robotic drone ship at sea.
SpaceX CEO Elon Musk said he felt “quite giddy” before the launch. “What I find strange about this flight is normally I feel superstressed out the day before,” he told reporters in a press briefing on Monday. “This time I don’t.”
Despite widespread opposition from medical and mental health organizations, tens of thousands of LGBTQ youth in the U.S. will be subjected to anti-gay “conversion therapy” during their lifetime, a new report estimates.
Released this month by the Williams Institute at University of California, Los Angeles, School of Law, the report estimates that 698,000 LGBTQ Americans between the ages of 18 and 59 have undergone conversion therapy at some point in their lives. About 350,000 of those received that treatment as adolescents.
The report also estimates that 20,000 LGBTQ youths currently between the ages of 13 and 17 will be subjected to conversion therapy from a licensed health care professional before they turn 18. An additional 57,000 will be subjected to the controversial practice from a religious or spiritual adviser before age 18.
The study’s lead author, Christy Mallory, believes the results may surprise many Americans in the wake of marriage equality and other social strides made on behalf of the LGBTQ community.
In what is being described as a “first,” lifeguards successfully deployed a drone to rescue two boys in trouble while swimming off the eastern coast of Australia Thursday.
It was all a bit of serendipity, too. Members of the Australian Lifeguard Service just happened to be training with the drone — which is being developed to spot sharks — when they got word that the swimmers were having difficulty nearby as they encountered a 9-foot swell in rough surf conditions, according to the surf lifesaving website in New South Wales.
And the man piloting the drone at the time just happened to be Jai Sheridan, the 2017 New South Wales Lifeguard of the Year.

In this remote outpost in Siberia, the cold is no small affair.
Eyelashes freeze, frostbite is a constant danger and cars are usually kept running even when not being used, lest their batteries die in temperatures that average minus-58 degrees Fahrenheit in the winter, according to news reports.
This is Oymyakon, a settlement of some 500 people in Russia’s Yakutia region, that has earned the reputation as the coldest permanently occupied human settlement in the world.
It is not a reputation that has been won easily. Earlier this week, a cold snap sent temperatures plunging toward record lows, with reports as extreme as minus-88 degrees Fahrenheit. The village recorded an all-time low of minus-98 degrees in 2013.
Though schools in the area remain open as temperatures dip into the minus-40s, they were closed on Tuesday, the Associated Press reported.

A day after powerful mudslides swept through the Southern California community of Montecito, rescue crews continued to search the wreckage for missing people on Wednesday.
The disaster left at least 15 people dead, the Santa Barbara County Sheriff’s Office tweeted Wednesday. At least 25 people have been injured in the mudslides, while more than 50 people were rescued by air, officials said. Over two dozen people were unaccounted for as of Wednesday morning, The New York Times reported.
And those numbers will likely rise, as authorities told the AP flash floods have destroyed 100 single-family homes and damaged 300 more in Santa Barbara County.

Former astronaut John Young, a NASA trailblazer whose six journeys into space included a walk on the moon and commanding the first space shuttle flight, died Friday after complications from pneumonia, NASA said Saturday.
He was 87.

“NASA and the world have lost a pioneer. Astronaut John Young’s storied career spanned three generations of spaceflight; we will stand on his shoulders as we look toward the next human frontier,” NASA Administrator Robert Lightfoot said.

You may be over the bitter cold, but the bitter cold isn’t over.
More than 120 million Americans in a large swath of the eastern United States woke up Saturday to frigid temperatures. Cities such as Boston, New York and Philadelphia were in the single digits with wind chills in some regions, including New England, expected to make temperatures feel as low as 25 to 40 degrees below, according to the National Weather Service.
In Portland, Maine, temperatures were set to reach a high of only 5 degrees below and a low of 20 degrees below, the NWS said. Highs were also expected to remain in the single digits across the lower Great Lakes stretching down to the Carolinas.
