A hippopotamus attacked and killed a tourist in Kenya over the weekend, the Kenya Wildlife Service (KWS) said in a tweet Sunday.The attack took place Saturday evening at Lake Naivasha, about 58 miles from the Kenyan capital of Nairobi. Chang Ming Chuang, 65, was with a colleague taking pictures of the hippo on the shores of the lake when the animal attacked.Chuang was taken to the Naivasha District Hospital, where he was pronounced dead. Chuang's colleague, Wu Peng Te, 62, survived the attack with minor bruises and is recovering at the Naivasha Sopa Resort, the wildlife service said. KWS is tracking the hippo.The KWS identified the victim as a Chinese tourist. Taiwan's foreign ministry has since confirmed that the two tourists involved in the attack were from the self-governed island. 803

A Florida man is accused of attacking a Volusia County ambulance crew on the way to the hospital Sunday night.The paramedics told deputies that the suspect, David W. Parsons, 33, had been belligerent throughout the evening. The paramedic who was driving the ambulance said he looked in the rear-view mirror and saw Parsons getting off the stretcher and attacking the paramedic riding in the back.The ambulance driver said he pulled over, opened the back door and found Parsons with the paramedic in a choke hold.The driver said he then put Parsons in a choke hold until he released the other paramedic. Deputies said the altercation then spilled out of the ambulance.The sheriff's office said Parsons then attempted to run at them and into oncoming traffic, where the altercation continued.Deputy Micah Stoltz arrived and found Parsons putting a paramedic in a choke hold on the side of the road. The suspect was straddling one paramedic while the other was trying to pull him off.Stoltz had to use his stun gun after repeated commands to let go of the paramedic.The paramedics were in good condition after the attack and scuffle.Parsons was later medically cleared at Florida Hospital DeLand before being transported to the Volusia County Jail. He remained held Monday afternoon on ,000 bail, charged with two felony counts of battery on an EMT. 1387

A genetic analysis of COVID-19 patients suggests that blood type might influence whether someone develops severe disease.Scientists who compared the genes of thousands of patients in Europe found that those who had Type A blood were more likely to have severe disease while those with Type O were less likely.Wednesday’s report in the New England Journal of Medicine does not prove a blood type connection, but it does confirm a previous report from China of such a link.“Most of us discounted it because it was a very crude study,” Dr. Parameswar Hari, a blood specialist at the Medical College of Wisconsin, said of the report from China. With the new work, “now I believe it,” he said. “It could be very important.”Other scientists urged caution.The evidence of a role for blood type is “tentative ... it isn’t enough of a signal to be sure,” said Dr. Eric Topol, head of the Scripps Research Translational Institute in San Diego.The study, involving scientists in Italy, Spain, Denmark, Germany and other countries, compared about 2,000 patients with severe COVID-19 to several thousand other people who were healthy or who had only mild or no symptoms. Researchers tied variations in six genes to the likelihood of severe disease, including some that could have a role in how vulnerable people are to the virus. They also tied blood groups to possible risk.Most genetic studies like this are much larger, so it would be important to see if other scientists can look at other groups of patients to see if they find the same links, Topol said.Many researchers have been hunting for clues as to why some people infected with the coronavirus get very ill and others, less so. Being older or male seems to increase risk, and scientists have been looking at genes as another possible “host factor” that influences disease severity.There are four main blood types — A, B, AB and O — and “it’s determined by proteins on the surface of your red blood cells,” said Dr. Mary Horowitz, scientific chief at the Center for International Blood and Marrow Transplant Research.People with Type O are better able to recognize certain proteins as foreign, and that may extend to proteins on virus surfaces, Hari explained.During the SARS outbreak, which was caused by a genetic cousin of the coronavirus causing the current pandemic, “it was noted that people with O blood type were less likely to get severe disease,” he said.Blood type also has been tied to susceptibility to some other infectious diseases, including cholera, recurrent urinary tract infections from E. coli, and a bug called H. pylori that can cause ulcers and stomach cancer, said Dr. David Valle, director of the Institute of Genetic Medicine at Johns Hopkins University.Bottom line: “It’s a provocative study. It’s in my view well worth publishing and getting out there,” but it needs verification in more patients, Valle said.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

A Houston school has removed a quote popularized by a former New York madam after social media controversy over the saying, which was posted in a hallway above school lockers, according to CNN affiliate KTRK.The quote: "The more you act like a lady, the more he'll act like a gentleman."The decal letters were taken down Saturday, school district officials told KTRK. 375
