As summer winds down, doctors across the country are warning flu season is fast approaching. Many are watching Australia to see what may happen here when flu season arrives."Where Australia is obviously in the Southern Hemisphere, they're in winter while we’re in summer. We look at their flu season as kind of a six-month predictor of how ours is going to turn out," says Dr. Kenny Banh, the assistant dean of undergraduate medical education at UCSF-Fresno.The number of flu cases in Australia has taken a dramatic dip compared to last year. Dr. Banh says it's unclear if the U.S.'s flu rates will be as low as Australia's.A lot of it has to do with coronavirus precautions that people are taking, Banh hypothesizes."That's what we predict. It's not really so much a change in vaccination rates as much as the social distancing and all the preventative steps of coronavirus that are having the same effect of spreading any disease, including influenza," says Dr. Banh.Doctors say strict measures in Australia to protect people from COVID-19, such as physical distancing, wearing masks and hand washing, have helped prevent the spread of the virus and, incidentally, the flu. Now, some are wondering whether the United States will also see a drop in flu cases this winter."Seeing that they have a drop in influenza, we will certainly have a small influenza season. The issue is Australia is approaching, and the U.S. is approaching coronavirus very different. Their rates are different and they have a much lower per capita infection rate than we have in the U.S. for various reasons," says Dr. Banh.Australia has taken a broader, nationwide approach to protecting people against COVID-19, unlike in the United States, where each state has implemented different restrictions. That's one reason why Dr. Tanya Altmann with the American Academy of Pediatrics recommends every person, 6 months of age and older, gets a flu vaccine."I think this winter, it may be hard to differentiate between the flu and COVID-19 because so many of the symptoms-- cough, fever, aches, chills, are very similar. So by getting the flu vaccine and decreasing the chance your child has influenza, that will help us figure it out," says Dr. Altmann.Dr. Banh says Australia's plummeting flu rates and nationwide protective measures from COVID-19 will hopefully encourage many here in the United States to take the necessary precautions to keep everyone as healthy as possible this winter. 2470

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329

As the coronavirus pandemic surges across the nation and infections and hospitalizations rise, medical administrators are scrambling to find enough nursing help — especially in rural areas and at small hospitals.Nurses are being trained to provide care in fields where they have limited experience. Hospitals are scaling back services to ensure enough staff to handle critically ill patients. And health systems are turning to short-term travel nurses to help fill the gaps.Adding to the strain, experienced nurses are “burned out with this whole (pandemic)” and some are quitting, said Kevin Fitzpatrick, an emergency room nurse at Hurley Medical Center in Flint, Michigan, where several left just in the past month to work in hospice or home care or at outpatient clinics.“And replacing them is not easy,” Fitzpatrick said.As a result, he said, the ER is operating at about five nurses short of its optimal level at any given time, and each one typically cares for four patients as COVID-19 hospitalizations surge anew. Hospital officials did not respond to requests for comment.But the departures are not surprising, according to experts, considering not only the mental toll but the fact that many nurses trained in acute care are over 50 and at increased risk of complications if they contract COVID-19, while younger nurses often have children or other family to worry about.“Who can actually work and who feels safe working are limited by family obligations to protect their own health,” said Karen Donelan, professor of U.S. health policy at Brandeis University’s Heller School for Social Policy and Management. “All of those things have been factors.”Donelan said there is little data so far on how the pandemic, which has killed more than 231,000 people in the country, is affecting nursing overall. But some hospitals had a shortage even before the virus took hold, despite a national rise in the number of nurses over the past decade.With total confirmed coronavirus cases surpassing 9 million in the U.S. and new daily infections rising in 47 states, the need is only increasing.Wausau, Wisconsin-based Aspirus Health Care is offering ,000 signing bonuses for nurses with at least a year of experience and hiring contract nurses through private staffing companies to handle a surge in hospitalizations that prompted the system to almost quadruple the number of beds dedicated to COVID-19 patients.Aspirus, which operates five hospitals in Wisconsin and four in small communities in Michigan’s Upper Peninsula, also is moving nurses around between departments and facilities as hot spots emerge, said Ruth Risley-Gray, senior vice president and chief nursing officer at Aspirus.Outside help still is needed, in part because some nurses have gotten sick from or were exposed to the cornavirus during the current wave, which “came with a vengeance” starting in August, Risley-Gray said. At one point in mid-October, 215 staffers were in isolation after showing symptoms or being exposed to someone who tested positive, and some are just starting to return to work.Aspirus recently was able to hire 18 nurses from outside agencies, and may need more if the surge continues.Because the pandemic is surging just about everywhere in the country, hospitals nationwide are competing for the same pool of nurses, offering pay ranging from ,500 a week to more than ,000, said April Hansen, executive vice president at San Diego-based Aya Healthcare, which recruits and deploys travel nurses.She said demand for their services has more than doubled since early in the pandemic when the greatest need was in hot spots like New York and New Jersey and then moved to southern states. In recent weeks the virus has been spiking across the country, with the new hot spots in places like the rural upper Midwest and southern-border communities such as El Paso, Texas.Now placing nurses where they’re needed is “like a giant game of whack-a-mole,” said Hansen, whose company has about 20,000 openings for contract nurses.In North Dakota, where infection rates are exploding, hospitals may cut back on elective surgeries and seek government aid to hire more nurses if things get worse, North Dakota Hospital Association president Tim Blasl said.In Texas, Gov. Greg Abbott recently announced he was sending 75 nurses and respiratory therapists to El Paso to help handle the city’s surge. Wisconsin Gov. Tony Evers, meanwhile, issued emergency orders making it easier for nurses from elsewhere to practice in his state and for retired nurses to come back.“This has been a challenge, and we’ve been pleading with the community members to protect themselves and others,” by wearing masks and social distancing, said Aspirus’ Risley-Gray, who said the positivity rate among community members tested by Aspirus rose from under 10% in September to 24% last week.To combat the emotional toll and fatigue that comes with caring for COVID-19 patients, including just donning and removing protective equipment all day, Aspirus has been giving nurses microbreaks and quiet places to get away and collect themselves when they feel overwhelmed.Travel nurses say the need at small hospitals tends to be greater than at larger facilities.Robert Gardner, who’s currently assigned to a hospital in a small town about 20 miles west of Atlanta, said he did search and rescue in the Coast Guard during Hurricane Katrina and the pandemic is “a lot worse.”He worked at a large New Jersey hospital when that state was swamped by the virus in the spring, and now worries that flu season could bring further chaos to hospitals. But he’s determined to stick it out, no matter what.“It’s not even a question,” Gardner said. “Nursing is a calling.” 5727

As the NBA plans to resume action at the end of the month, the bubble the league has implemented in Orlando, Florida, appears to be working.On Monday, the league said that its latest round of tests netted no new confirmed coronavirus cases.The league has implemented a “bubble” for its players, meaning players are being confined to a hotel complex as Florida is grappling with a spike in recent weeks of COVID-19 cases. The complex also contains practice gyms for the players to workout.At the end of June, before players entered the “bubble,” the league found 16 coronavirus cases out of over 300 tested.The NBA is moving forward with a planned relaunch on July 30, with 22 teams of the league’s 30 teams participating in the conclusion of the season and subsequent postseason based at Orlando’s Wide World of Sports. Fans will not be allowed to watch in person.The league suspended play on March 11 when Utah Jazz star Rudy Gobert tested positive for COVID-19 moments before tipoff in a game against the Oklahoma City Thunder. Several games were allowed to conclude that evening, but the NBA has not held a game since. 1129

As millions of Americans have been without work amid the pandemic, nearly 12 million people will lose unemployment benefits on December 26, according to the Century Foundation.The Century Foundation estimates that 7.3 million Americans will exhaust benefits from the Pandemic Unemployment Assistance program. The federal program extended unemployment benefits for millions of Americans who otherwise would not have received state unemployment benefits.According to the Century Foundation, 4.6 million Americans will lose benefits through the Pandemic Emergency Unemployment Compensation program on December 26. This fund extended state unemployment benefits for an additional 13 weeks. The 4.6 million Americans is in addition to the 3.5 million workers who will have lost PEUC benefits by then.“Congress has stared down major expirations of jobless benefits multiple times during the Great Recession and previous economic cycles,” the Century Foundation said. “Policy makers have been more comfortable with enacting temporary extended benefits programs with more predictable costs rather than improving the automatic stabilizers in (extended benefits) EB."While millions of Americans are set to lose benefits, there remains ongoing debate on Capitol Hill to provide some form of economic stimulus. There have been various proposals that would offer extended benefits, but the House, Senate and White House have struggled to find any sort of agreement.“With the stakes of the benefit cutoff perhaps higher than they have ever been before, there also seems to be a grave danger that unemployed Americans could be left behind during a lame duck session taking place in the overhang of a contested presidential election,” the Century Foundation said. “But the numbers—and families behind them—leave no excuses for inaction.” 1829
