A person with direct knowledge of the decision tells The Associated Press the Dallas Stars have placed former first-round draft pick Valeri Nichushkin on waivers to buy out the final year of his contract. The person spoke to the AP on the condition of anonymity because the Stars did not announce the move made Saturday, two days before the start of the NHL’s free agency period. The 24-year-old Nichushkin is from Russia and was selected by Dallas with the 10th pick in the 2013 draft. The forward had no goals and 10 assists in 57 regular-season games last year and appeared in just one playoff game. Overall, Nichushkin had 23 goals and 51 assists in 223 games with Dallas over four seasons. He was set to count $2.95 million against the Stars’ salary cap next season. The Vancouver Canucks announced they placed center Ryan Spooner on waivers to buy out the final year of his two-year, $8 million contact. The seventh-year player had three goals and nine points in 52 games with the … [Read more...] about Stars place Nichushkin on waivers for buyout

(AP Photo/Michael Ainsworth) DALLAS (AP) — Luka Doncic left the game early with a sprained ankle, and the Dallas Mavericks rallied from 24 points down without their young star before falling to the Miami Heat 122-118 in overtime Saturday night. Bam Adebayo put Miami in front for good on a put-back dunk with 1:15 remaining in overtime and finished with 18 points, 11 rebounds and 10 assists for his second triple-double in three games. Without Doncic, Tim Hardaway Jr. scored 18 of his 28 points in the second half to help Dallas rally, but was shut out in overtime.

Calculus is a branch of mathematics that explores variables and how they change by looking at them in infinitely small pieces called infinitesimals. Calculus, as it is practiced today, was invented in the 17th century by British scientist Isaac Newton (1642 to 1726) and German scientist Gottfried Leibnitz (1646 to 1716), who independently developed the principles of calculus in the traditions of geometry and symbolic mathematics, respectively. While these two discoveries are most important to calculus as it is practiced today, they were not isolated incidents. At least two others are known: Archimedes (287 to 212 B.C.) in Ancient Greece and Bhāskara II (A.D. 1114 to 1185) in medieval India developed calculus ideas long before the 17th century. Tragically, the revolutionary nature of these discoveries either wasn't recognized or else was so buried in other new and difficult-to-understand ideas that they were nearly forgotten until modern times.The word "calculus" has … [Read more...] about What Is Calculus?
One of the world's deepest earthquakes was also a rare supersonic quake, upending ideas about where these unusual earthquakes strike.Only six supersonic (or supershear) earthquakes have ever been identified, all in the last 15 years. Until now, they all showed similar features, occurring relatively near the Earth's surface and on the same kind of fault. But last year, a remarkably super-fast and super-deep earthquake hit below Russia's Kamchatka Peninsula, breaking the pattern."This was very surprising," said Zhongwen Zhan, lead author of the study, published today (July 10) in the journal Science. "It's not only deep, it's supershear, and it's also quite small."The weird earthquake struck May 24, 2013, about 398 miles (642 kilometers) beneath the Sea of Okhotsk offshore of the Kamchatka Peninsula. The magnitude-6.7 quake was an aftershock to the largest deep earthquake on record, a magnitude 8.3 that also hit May 24.

Astronauts typically try to avoid starting fires in space, but new research on the behavior of flames in orbit could have benefits closer to home. In fact, this fiery research could lead to more-efficient car engines that contribute less pollution to the environment, according to a new study.A series of experiments aboard the orbiting complex is investigating "cool-burning" flames in space — a type of fire that burns at lower temperatures than ordinary flames on Earth. Blazes on this planet typically burn at between 2,240 degrees and 3,140 degrees Fahrenheit (1,225 degrees and 1,725 degrees Celsius). Cooler flames produced in microgravity burn at temperatures of between 440 degrees and 980 degrees Fahrenheit (227 degrees and 527 degrees Celsius).In the space station experiments, researchers ignited droplets of heptane fuel. These types of fires are possible on Earth, but they are typically short-lived, flickering out almost immediately, the researchers said. In microgravity, … [Read more...] about ‘Cool-Burning’ Space Flames Could Make Greener Cars
It started in late May.When geoecologist Steffen Zuther and his colleagues arrived in central Kazakhstan to monitor the calving of one herd of saigas, a critically endangered, steppe-dwelling antelope, veterinarians in the area had already reported dead animals on the ground."But since there happened to be die-offs of limited extent during the last years, at first we were not really alarmed," Zuther, the international coordinator of the Altyn Dala Conservation Initiative, told Live Science.But within four days, the entire herd — 60,000 saiga — had died. As veterinarians and conservationists tried to stem the die-off, they also got word of similar population crashes in other herds across Kazakhstan. By early June, the mass dying was over. [See Images of the Saiga Mass Die-Off]Now, the researchers have found clues as to how more than half of the country's herd, counted at 257,000 as of 2014, died so rapidly. Bacteria clearly played a role in the saigas' demise. But exactly … [Read more...] about 60,000 Antelopes Died in 4 Days — And No One Knows Why
