The Vegas Golden Knights routed the Florida Panthers 9-3 yesterday, winning the best-of-seven Stanley Cup Finals, the National Hockey League’s championship, four games to one. The win caps the Golden Knights’ swift rise from expansion team to member of the upper echelons of the league.

The Golden Knights took an early two-games-to-none lead in the series. The Panthers won a come-from-behind overtime win in game three, but their star forward Matthew Tkachuk fractured his sternum during the contest and was not a major factor in the rest of the series.

With a 10-game point (goals plus assists) streak and 13 goals and 12 assists overall, forward Jonathan Marchessault won the Conn Smythe Trophy for the playoffs’ most valuable player. Marchessault, one of the six remaining players on Vegas’s roster from its inaugural season in 2017, defeated the team that had let him go. In fact, the Panthers traded Reilly Smith to Vegas so they would take Marchessault instead of defensemen Alex Petrovic and Mark Pysyk during the expansion draft. The French-Canadian burned his former team to the tune of four goals and four assists.

Marchessault’s partner in the withering Vegas offense was veteran center Jack Eichel. Eichel scored six goals and had 20 assists in the Golden Knight’s playoff run. After goaltender Laurent Brossoit was injured during the second round, backup Adin Hill helped guide Vegas through a grueling six-game barnburner against the Dallas Stars. The series featured three overtime games and two shutouts from Hill.

The Panthers were the Cinderella story of the Stanley Cup Playoffs. They snuck into the tournament with the fewest standings points (92, with two points awarded per win and one point awarded for each overtime loss) of any playoff team. They were paired against the mighty Boston Bruins in the first round. Odds-on favorites to win the Cup, the Bruins had set the NHL records for wins (65 in an 82-game season) and standings points (135). But Florida stunned the hockey world by knocking off Boston in seven games. The upstart Panthers then dispatched the formidable Toronto Maple Leafs in five games and the Carolina Hurricanes in four to reach the Finals.

The Vegas Golden Knights have a short history filled with success. In 2017, the NHL held an expansion draft that allowed the Golden Knights to pick players from other teams. Responding to past expansion teams in the NHL and other sports being mired in mediocrity for years, the league reduced the number of players each team could “protect” from being picked by the new team. Vegas took advantage of the new draft rules and had one of the best inaugural seasons by an expansion franchise in any major professional sport. They finished first in the Pacific Division and made it to the Stanley Cup Finals, but lost to the Washington Capitals. Overall, Vegas has made the playoffs in five of its first six seasons.

Until 2017, Las Vegas had no major professional sports teams. Due to relaxing attitudes towards sports betting and a booming population, that situation quickly changed. Now, the city has a championship NHL team and a National Football League (NFL) team (the Raiders, who moved from Oakland in 2020). Furthermore, on the day the Knights won the Cup, the Nevada state senate passed a bill to fund $380 million towards building a Major-League-Baseball-caliber ballpark on the Las Vegas Strip. The legislative approval was seen as the last major hurdle for the Athletics, currently of Oakland, to move to the state.

With many of its star players signed on for next year, the Golden Knights will remain the bright center of the newly-formed Vegas sports solar system.

This summer, the entire globe experienced a heat wave. Western states in America experienced a record-breaking heat wave in late August and early September of 2022.

A heat wave is a period over which the temperature rises well above normal for a particular region. Heat waves may be less dramatic than such natural disasters as hurricanes, earthquakes, or tornadoes, and heat waves tend to cause less damage to property. However, heat waves rank among the deadliest extreme weather.

The varying nature of local climate makes it difficult to establish a simple definition of a heat wave. The temperatures of a heat wave must be hot relative to the average temperatures at a place during a particular time of year. For example, a temperature of 90 °F (32 °C) during the summer is not out of the ordinary for the northern African country of Sudan. However, it would be an exceptionally high temperature for the northern U.S. state of Alaska. Meteorologists agree that high temperatures must persist for more than one full day to be considered a heat wave.

This chart can be used to determine the heat index (HI), a number that describes how people are affected by the combination of temperature and relative humidity. As the temperature and relative humidity rise, the heat index increases. The higher the index, the greater the likelihood that people will develop heat-related illnesses. The risk of illness is low when the index is below 80 °F.

Heat waves are sometimes accompanied by high relative humidity. Relative humidity is the amount of water vapor in the air compared with the amount the air can hold at saturation. High relative humidity interferes with the human body’s ability to cool itself through the evaporation of sweat. Thus, high humidity can make a heat wave more uncomfortable and dangerous. Some weather agencies make use of a measure called the heat index, which factors in relative humidity to give a measure of how hot the air feels.

Heat waves are generally created by areas of high air pressure. Meteorologists call these areas highs or anticyclones. Warm highs bring high temperatures and air that contains little moisture. These highs are large weather systems that may affect a region for an extended time. In the summer, a warm high sometimes stalls over North America, for example, causing a heat wave.

The high temperatures of a heat wave can cause dehydration and hyperthermia in people and in animals. Dehydration is a condition in which the body loses too much water. In severe cases, dehydration can lead to a fast heartbeat, low blood pressure, shock, and death. Hyperthermia is a condition that occurs when the body becomes overheated. Forms of hyperthermia include heat exhaustion, heat cramps, and heatstroke (also called sunstroke). Heatstroke is a serious condition that can cause permanent neurological damage and death.

Elderly people, infants, and people with long-term illnesses may suffer heatstroke more readily than others during a heat wave. Hyperthermia can be particularly dangerous for people with long-term medical conditions. Such conditions as asthma, diabetes, heart failure, and high blood pressure place the body’s organs under stress. The added stress from hyperthermia can induce heart attack, breathing failure, and other fatal medical events among such people.

The complexity of diagnosing heat-related deaths has made it difficult for experts to track the toll of heat waves. The World Health Organization estimated that heat waves killed more than 166,000 people between 1998 and 2017. Another study found that approximately 500,000 heat-related deaths occurred worldwide between 2000 and 2019. Despite the uncertainties, experts agree that heat waves are deadly. In 2003, for example, Europe suffered a catastrophic heat wave in which some 70,000 people died.

Heat waves can also put stress on electric power and water services. People’s use of air conditioning strains the electrical grid. Power plants may need more water for cooling. People may also use more water to try to keep cool. When demand for electricity exceeds generating capacity, officials may have to reduce voltage to prevent a blackout. Such a reduction, called a brownout, may damage electrical equipment or cause the equipment to operate less efficiently. High temperatures also buckle pavement and warp railroad tracks.

Heat waves are dangerous to plants and animals as well. Excessive temperatures can kill animals that cannot find ways to keep cool. Prolonged heat can wither plants. Droughts usually accompany heat waves, compounding the danger to living things. Heat waves and droughts dry out the ground and plants, increasing the likelihood and severity of wildfires.

Data suggest that heat waves are increasing in duration, frequency, and intensity. The time of year in which heat waves occur is also expanding. Most climatologists think that climate change brought about by human-caused global warming is driving these changes.

People must exercise caution during heat waves to avoid health problems. Experts advise wearing light-colored, loose-fitting clothing when outdoors and avoiding going out during the hottest part of the day. People should drink fluids regularly but avoid beverages with alcohol or caffeine, which can contribute to dehydration.

People who are homeless or who live in homes without air conditioning are particularly vulnerable to heat waves. During a heat wave, local governments may open air-conditioned cooling centers where people can stay to cool down.

People can help to protect their community during a heat wave. They can air condition their homes only to what temperature is necessary, conserving power. People might be asked to limit water use at certain times to prevent drops in their community’s water pressure. They may be asked to conserve water if the heat wave is accompanied by a drought. Because heat waves increase the risk of wildfires, people may be prohibited from starting fires outdoors.

Today, January 10, is the third and final day of the Consumer Electronics Show (CES), the largest digital technology exhibition in the world. CES takes place every year in Las Vegas, Nevada, drawing thousands of tech companies large and small from all corners of the world. Such tech giants as Amazon, Google, and Samsung exhibit their latest products alongside those of small tech manufacturers, developers, and suppliers hoping to grow or get noticed. More than 4,400 companies are represented at this year’s CES, including 21 different companies whose names begin with smart, from Smart Adserver USA to SmartyPans, Inc.

CES is owned and produced by the Consumer Technology Association, the standards and trade organization that represents the massive U.S. consumer technology industry. This year, CES sprawls over 11 official venues covering nearly 3 million square feet (280,000 square meters). About 170,000 tech professionals attend CES each year (including more than 60,000 people from outside the United States) to display and market, but also to attend conferences and see and play with the latest tech gadgets. Attendees need maps to navigate the venue groups—Tech East, Tech West, and Tech South—and patience to wade through the throngs of people distracted by massive video boards, robots, and a host of other electronic bells and whistles.

The first CES took place in New York City in June 1967. It proved popular and grew quickly along with the consumer technology industry. From 1978 to 1994, CES had two shows per year—a winter exhibition in Las Vegas and a summer show in Chicago. CES has concentrated on just one major Las Vegas event per year since 1998. Numerous consumer electronics have made their debuts at CES, including videocassette recorders (VCR’s) and laser discs in the 1970′s; camcorders and compact discs (CD’s) in the 1980′s; and interactive and satellite technologies, digital versatile discs (DVD’s), high definition television (HDTV), and satellite radio in the 1990′s. Since the early 2000′s, Microsoft Xbox, plasma televisions, blu-ray DVD’s, HD radio, tablets, notebooks, Android devices, smart appliances, driverless cars, 3D printers, wearable technologies, and varying levels of virtual reality have all been seen for the first time at CES. This year’s CES features more than 200 new products as well as innovations in artificial intelligence, cloud services, cyber security, digital health services, drones, mobile payments, and 5G wireless technology.

October 2, 2017

Last night, on October 1, in Las Vegas, Nevada, a gunman killed at least 58 people at an open-air concert near the Mandalay Bay Resort and Casino. The gunman fired from the window of his hotel room on the 32nd floor of the Mandalay Bay, shooting into a crowd of 22,000 people attending a music festival across the street. Armed with numerous automatic weapons, the gunman poured hundreds of bullets into the crowd until police reached his hotel room. The gunman then committed suicide. The attack—which has also resulted in over 500 injuries—is the deadliest mass shooting in United States history. The death toll from the domestic terror attack will most likely rise.

The attack began just after 10 p.m. local time, not long after country music star Jason Aldean had taken the stage at the Route 91 Harvest music festival, a three-day event held in an open-air venue across the Las Vegas Strip from the Mandalay Bay. The Las Vegas Strip, a portion of Las Vegas Boulevard, is famous for its large resort hotels and casinos. Many people in the concert crowd did not react immediately to the attack, as the popping of gunshots was confused with the sound of firecrackers and drowned out by the music being played on stage.

People soon realized the horror of what was taking place, however, and began running for cover and searching for loved ones in the chaos. The shooting paused occasionally as the gunman reloaded his automatic weapons, but the rapid fire then resumed as bullets ricocheted around the concrete concert ground and inflicted further injuries. Police responding to the attack saw gun flashes coming from the Mandalay Bay, and soon zeroed in on the gunman’s locked hotel room. As police used explosives to burst into the room, the gunman shot and killed himself.

Thus far, the shooter, identified as 64-year-old Stephen Paddock, has not been tied with any militant or terrorist groups, and his motive remains unclear. Paddock lived in Mesquite, a small city northeast of Las Vegas. His dead body was found with 23 guns, many of which are readily available in Nevada, a state with some of the least stringent gun laws in the United States. Police found another 19 guns at Paddock’s home in Mesquite.

The previous worst U.S. mass shooting occurred just last year, in June 2016, when a gunman killed 49 people at a gay nightclub in Orlando, Florida. That shooter, who was killed by police, had professed his allegiance to an Islamic terrorist group.
