A relaxing swim in the ocean after a day of training suddenly changed when a shark got close to a coast guard group, prompting crewmembers to fire shots in the water to scare the animal away.Members of the Coast Guard Cutter Kimball had completed operations for the day “a zillion miles from land” and “had not been off the ship for weeks,” they said in a Facebook post describing the encounter. USCGC Kimball is based in Honolulu.The group decided to go for a swim complete with an inflatable unicorn, and utilized a “fully vetted and tested plan we’ve used before” which included safety briefs, a small boat stationed 50 yards out and “an armed shark watch.”Then, over the radio, a call comes over “shark!” 716

A team at the University of Kentucky is researching a possible treatment for COVID-19 and key helpers are three alpacas; Big Boy, Blue Eyes and Emperor.“It’s a powerful technology that we have at UK (University of Kentucky) and it’s something that hopefully we can develop some therapeutics with,” said Wally Whiteheart, a professor in the Department of Molecular & Cellular Biochemistry.Alpacas, along with llamas and camels, make a special kind of antibody called a nanobody. Nanobodies can be useful in cancer research and for other diseases. Researchers, led by Whiteheart and fellow professor Lou Hersh, are working with a nearby ranch to see what impact alpacas could have on COVID-19.“We, in a sense vaccinate them, and this case with viral proteins, and we make nanobodies to those viral proteins,” explained Whiteheart. “We can then go and purify and identify the nanobodies that bind to the virus and then test them to see if they can inhibit viral infection.”Making the nanobodies is just the first step. The team will see which, if any, can block virus infection and those candidates could move on to clinical trials.There’s still a lot of research and testing to go, and also still a lot of hope.“The cool thing which we’re exploring now is the fact that you might be able to use them as a nasal spray and this actually gets them to the place where the virus is affecting lung tissue,” said Whiteheart.This isn’t the first time the trio of alpacas has helped medical research. Big Boy, Blue Eyes and Emperor have contributed to the university’s nanobody research for more than three years. In that time, they have helped researchers generate more than 50 nanobodies to target proteins involved in a variety of human diseases including cancer, diabetes and neurological disorders.This story was originally reported by Alex Valverde on LEX18.com. 1869

A shooter opened fire at a church in the Northern Caucasus region of southern Russia on Sunday, killing five people and wounding two others, authorities said, according to state media.The incident took place at a church in Kizlyar in the restive Russian republic of Dagestan.Police responded, traded fire with the shooter and killed him, the authorities said. Two officers were injured in the gunfight, they said.The shooting occurred during Maslenitsa, a festival celebrated in Russia that is full of dancing, lots of pancakes and carnival-like festivities.Russian state news agency Tass spoke to a law enforcement source who said that "the unknown person opened fire on people celebrating Maslenitsa."Kizlyar Mayor Alexander Shuvalov was quoted by Tass as saying that the attacker opened fire on "people after leaving the service."It was not immediately known who was behind the attack.Dagestan and its neighbor Chechnya have been wracked by separatist and Islamic violence in recent years. 1010

A meteor shower that occurs annually due to Earth passing through dust released by Halley's Comet is set to peak Tuesday and Wednesday.According to AccuWeather, observers should expect to see up to 20 meteors per hour when the Orionid meteor shower peaks.Space.com says between 1 to 5:45 a.m. local time is the best time to watch the meteor shower.According to the Weather Channel, it's best to avoid light pollution (if possible) and not use binoculars or telescopes if you want to view the shower. 507

A recent study appears to show a person’s blood type might indicate whether they will develop severe respiratory failure if they contract COVID-19.The study sequenced genomes of 1,600 COVID-19 patients in Spain and Italy who had been hospitalized with severe respiratory failure and compared the results to DNA sequences of 2,205 healthy subjects.Results appear to show that people with type A blood had a higher chance of developing severe respiratory failure as compared to people with O blood type. The study claims there may be a “protective effect” for blood group O. However this study has not been peer-reviewed yet and the exact kind or extent of “protective effect” is not known.In early June, the site 23andme.com released results from information gathered from 750,000 participants who identified they had COVID-19. The genealogy company said their research suggests a similar effect in people with O blood type. “Individuals with O blood type are between 9-18% percent less likely than individuals with other blood types to have tested positive for COVID-19, according to the data,” a company statement said.They said while there was a significant difference in those with O blood type, there “appeared to be little differences in susceptibility among the other blood types.”However, some are questioning this idea that people with type O blood are protected. Laura Cooling is the director of immunohematology at the University of Michigan. She noted that the idea that having type O blood is protective doesn’t match with current COVID-19 infection rates.Type O blood is usually more prevalent among African Americans, according to the American Red Cross, yet new information from the CDC and states indicate African Americans have experienced disproportionately high COVID-19 infection rates. Cooling says there are many factors to consider.“It’s what your blood type is, relative to the other person who exposed you, relative to all the other genetic and acquired health conditions you have,” she told Chemical and Engineering News on the matter. 2069
