The English city of Manchester came together Tuesday to mark the first anniversary of the terror attack that killed 22 people attending an Ariana Grande concert.Families of the victims, the injured, emergency services and local and national leaders were joined by UK Prime Minister Theresa May and Prince William, the Duke of Cambridge, for a memorial service at Manchester Cathedral.Those inside the cathedral were joined by thousands more across the country in a minute's silence to remember those killed in the suicide bombing as they left the Manchester Arena.Prince William read from Corinthians during a service full of song and tribute to the victims and their families. 685

The fog hangs heavy over Great Bay along the New Hampshire seacoast on a raw as Josh Carloni and his wife, Jessica, emerge through the mist on their fishing boat.They are the owners of Rising Tide Oyster Company, a family-owned business that typically sells thousands of oysters a year to restaurants across New England. But when the novel coronavirus hit back in March, their sales disappeared overnight as restaurants were forced to closed.“Every time you turn on the news, there’s just more bad news out there,” said Carloni. “Our business is down maybe 20 percent.”The Carlonis and oyster fisherman across the country were finding themselves in similar positions. They suddenly had thousands of perfectly healthy oysters that needed to be harvested, but there was no place for them to go.“Oyster farmers had been growing these oysters for three years, and suddenly, they didn’t have a market at all. The pandemic hit oyster farmers across the country hard,” explained Alix Laferriere, who serves as the Marine and Coastal Director for the Nature Conservancy of New Hampshire.Laferriere and her team thought there was little they could do to help struggling oyster farmers until a few months ago when an anonymous donor gifted a million donation.With that sudden infusion of cash, Laferriere and her team got to work. With help from the Pew Charitable Trust, they developed the Supporting Oyster Aquaculture and Restoration (SOAR) initiative to buy back five million oysters that needed to be harvested. The program is being deployed in seven states: Maine, New Hampshire, Massachusetts, New York, New Jersey, Maryland and Washington state.But it’s not just helping fisherman’s bottom line, it’s also helping estuaries and reefs at the bottom of the ocean.Turns out oysters don't just taste good; they can do good for the environment. That grant bought back 10,000 of Josh Carloni's oysters. And he isn't just throwing them into the ocean. Laferriere and her team have strategically told him where they should be deployed across the Great Bay Estuary along New Hampshire's coast. Eventually, the oysters will latch on to reefs below and help restore the damage done by decades of overharvesting, pollution and disease.“It’s this win-win opportunity where we get to put oysters back in the bay and help our local oyster farmers,” explained Briana Group, who also works with the Nature Conservancy of New Hampshire.One adult oyster can filter up to 30 gallons of water a day, and when they’re filtering that water, they’re removing nitrogen from the ecosystem.While the program is giving fisherman an infusion of cash, it’s also giving reefs and estuaries across the country an infusion of clean water, courtesy of a 3-inch mollusk.“There’s nothing bad about this situation; it’s only good,” Laferriere said as she looked out over the ocean.For fisherman like Josh Carloni, the program means he gets to keep his business afloat for another year, while at the same time, giving back to the environment. And it’s all because of COVID-19.“It makes us feel really good about doing something good for the environment,” he said. 3134

The excitement of two COVID-19 vaccines with more than 90 percent efficacy is undeniable.In November, both Pfizer and Moderna announced its scientists had developed vaccines with efficacy at or near 95 percent, but scientists are warning these vaccines are not the "silver bullet" to ending the pandemic.“We don’t want to give the public the impression that there’s an emergency use authorization and these vaccines become available in a small amount in December and we can go back to our pre-pandemic behavior,” said William Moss, executive director of the International Vaccine Access Center at Johns Hopkins.In June, the FDA released its vaccine guidelines, saying it would consider emergency use authorization for any vaccine testing with at least 50 percent effectiveness, so there is a reason for celebration, according to Moss, but only after certain questions about the vaccine are answered.Dr. Anthony Fauci has said the initial vaccines will prevent symptoms in those who become infected, rather than kill the virus itself. Moss says that means immunized people might be able to spread COVID-19 to others.He also wonders how long immunization will last. One year? Three years? Will booster doses be needed? They're all careful considerations that will only emerge once one is put into play, according to Moss.“It’s obviously tragic that the [COVID] cases are occurring that quickly, but it does help a vaccine trial because otherwise you just have to wait that much longer for samples to come in,” said Moss.The vaccine process has innovated how scientists and researchers approach these types of situations, however, according to Moss.In traditional vaccines, a small dose of the virus is injected into the body so the immune system can create antibodies. In the COVID-19 vaccine, though, both Moderna and Pfizer have used what is called messenger RNA (mRNA) where the virus’ genetic code is injected into the body so it can instruct cells on what antibodies to produce. Scientists say this way is faster, safer, and can create a stronger immune response as people are not exposed to the virus.“I suspect that if this all goes well and these vaccines are safe and continue to demonstrate 90 to 95 percent efficacy, we’re going to see other vaccines of a similar type,” said Moss. 2298

The COVID-19 pandemic has hit people of color particularly hard, and one new study says that may be because of racial disparities in treating high blood pressure.According to the American Heart Association's Scientific Sessions, one-third of disparities in treatment may be the result of racial inequalities in prescribing or increasing the dosage of new medications used in treating high blood pressure.The study found that blood pressure control rates are lower in Black patients compared to other racial groups. Black patients also had more missed opportunities for treatment and missed more clinic appointments."A doctor might think a patient is less likely less able to afford medications, and because of that, they choose to not prescribe a certain medication," said Dr. Valy Fontil, an assistant professor of medicine at UCSF and one of the researchers involved in the study. "Or, they might know this person doesn't have transportation to the clinic, and so sometimes it might even be well-intentioned."Fontil says more standardized treatment protocols would help eliminate the disparities and prevent missed opportunities to get someone the medication they need."Sometimes people present, and the main thing that they're there for is not for the blood pressure," he said. "So, the clinician just sort of kind of might ignore the blood pressure. So automating these sort of standardized treatments would tell the clinician that they — even if the patient's not here for blood pressure — you have to address it in some way."Previous studies have also shown Black patients have more apprehension about why someone is giving them more medication. Fontil says one solution is having the patient be part of the treatment decision making.Fontil adds that the increasing number of virtual visits for blood pressure issues could make the racial disparities even worse. 1876

The coronavirus continues to play havoc on college football teams throughout the United States as 15 Division 1 FBS games have been postponed or canceled for this weekend.Of the 15 contests, six involved AP Top 25 teams, including No. 1-ranked Alabama, No. 3 Ohio State and No. 5 Texas A&M. No conference has been impacted more than the SEC, which postponed four of its seven games scheduled for Saturday.The most anticipated matchup of the weekend, top-ranked Alabama versus defending national champion LSU, was postponed on Tuesday after LSU reported multiple COVID-19 cases.Maryland, who was scheduled to take on Ohio State, reported eight COVID-19 cases among its players.For schools with multiple coronavirus cases, a key issue is contact tracing and quarantining close contacts of those positive with the virus. The CDC recommends that anyone who has been within six feet for 15 minutes of someone infected with the virus to quarantine for up to two weeks.Texas A&M athletics direct Ross Bjork said contact tracing was a significant factor in postponing its game against Tennessee this weekend.“The nature of away game travel (flights, meals, lodging, locker room, etc.) naturally leads to an increase in the number of student-athletes, coaches and staff who meet the criteria for mandatory quarantine based on contact tracing guidelines,” Bjork said in a statement. “We are asking everyone around our university community to stay vigilant and follow all of the safety protocols and best practices as we approach the end of the fall sports seasons.”Here are the games postponed or canceled this weekend:No. 1 Alabama vs LSUNo. 3 Ohio State vs MarylandNo. 5 Texas A&M vs TennesseeNo. 12 Georgia vs MissouriNo. 15 Coastal Carolina vs TroyNo. 24 Auburn vs Mississippi StateMemphis vs NavyAir Force vs WyomingUL-Monroe vs Arkansas StateGardner Webb vs CharlotteNorth Texas vs UABRice vs Louisiana TechPittsburgh vs Georgia TechCalifornia vs Arizona StateUtah vs UCLA 1988
