Antibiotic resistance is one of the scariest challenges of our time. Just this week, researchers detected one in four samples from supermarket chickens in the UK contained antibiotic-resistant E. coli . Meanwhile, fears of drug-resistant superbugs continueto wrangle fears.
But more often than not, it’s hard to imagine how quickly this process can occur. So to demonstrate this, researchers from Harvard Medical School and Technion-Israel Institute of Technology have created a time-lapse video that clearly shows how rapidly and effectively bacteria can evolve to gain resistance to narcotics. The project is part of anew study published in Science.
The team started by making basically a massive square petri-dish, called the microbial evolution growth arena plate( MEGA) and introduced the ever-present bacterium E. coli to each end. They painted bands of antibiotics at periodic strips across the MEGA, which were dosed with increasingly higher concentrations as they moved inwards. The usually prescribed trimethoprim and ciprofloxacin were theantibiotics of choice.

You can see, in this gif and the video below, the bacteria march forward and hita level of antibiotics. The vast majority are stopped in their ways and killed off by the medication. However, a pocket full of drug-resistant mutants slip through. These mutants continueto survive and prosper until they reach the next band of even stronger antibiotics, and the same process occurs. Eventually, after 12 days, the bacteria managed to pass the final band of 1000x strength antibiotics.
Interestingly, it also broke a common assumption that the bacteria that survive the highest concentration of antibiotics are the most resistant.
What we assured is demonstrated that evolution is not always led by the most resistant mutants, Michael Baym, the studys leading author from Harvard, said in a statement. Sometimes it favors the first to get there. The strongest mutants are, in fact, often moving behind more vulnerable stress. Who gets there first may be determined in accordance with proximity rather than mutation strength.
Tami Lieberman, who also worked on the project, added: “This is a stunning demo of how quickly microbes evolve. When indicated the video, evolutionary biologists immediately distinguish theories theyve thought about in the abstract, while nonspecialists immediately begin to ask really good questions.”
A North Miami, Florida, police officer who shot an unarmed black mental health therapistwas identified Friday as a SWAT team member, and a police commandant accused of fabricating information about the shooting was suspended.
A lawyer for the wounded therapist, Charles Kinsey, meanwhile, told the Miami Herald he does not believe a police union official who claimed the shooting was an accident.
SWAT team member Jonathan Aledda was identified Friday as the policeman who fired three shots during the showdown Monday in which Kinsey was wounded in the leg.
Bystander video reveals Kinsey lying in the street with his hands up shortly before the shooting. Kinsey said he had been trying to calm a patient with autism who had run from a nearby group home. The patient’s toy truck apparently was misstep for a handgun by a 911 caller.
The cellphone footage adds another vivid flashpoint to recent controversial police shootings of black men in Baton Rouge, Louisiana, and Falcon Heights, Minnesota. Police officers, meanwhile, have been gunned down by ambushers in Dallas and Baton Rouge.
Aledda guessed Kinsey was at risk from the other man in the street, according to John Rivera, head of the Miami-Dade Police Benevolent Association. The policeman tried to shoot the man he thought was attacking Kinsey, but mistakenly shot Kinseyinstead, Rivera said.
Kinsey’s lawyer, Hilton Napoleon, on Friday cast doubt on the union leader’s explain. He said he didn’t believe that a SWAT team member with four years’ experience would be a poor shooter. Napoleon also said the policeman should have warned Kinsey to move away if the intended target was the other man.
Kinsey, in an interview from his hospital bed, said he asked Aledda why he shot him after he was hit. He said the policeman answered, “I don’t know .”
Aledda is on administrative leave while the authorities review what happened.
Police officials also suspended Commander Emile Hollantwithout pay for what North Miami City Manager Larry Spring Jr. said were inconsistencies in such statements about the shooting. Officials wouldn’t elaborate.

Reddit user lucyfferrecently took to the website to post about her ongoing recovery from anorexia. She describes how she still fights with body image issues, but feels healthy and happy thanks to some lifestyle changes. Her post concludes with asking anyone struggling with anorexia to reach out to her for help.
BroBible took her tale as an opportunity to declare that she is now smoking hot.
The BroBible piece frequently stumbles when it comes to reporting anorexia, comparing lucyffer to others struggling with disordered feeing by saying she now has a healthy relationship with food unlike some recover anorexics, and choosing to focus on her before and after photos.
The Daily Dot has reached out to the National Eating Disorders Association regarding this matter. President and CEO Claire Mysko explains that, while a dialogue about recovering from disordered feeing is important, so too is the approach to such a sensitive subject.
The road to recovery seems different for everyone, but the how we communicate about eating disorder should have one thing in commonsafety, Mysko says. Detailing ailment feeing practices and weight lows can be triggering for those working still struggling, so it’s important that we’re mindful of how we share stories. The focus should be on hope, health and subsistence rather than numbers, habits and graphic details.
According to the NEDA website, eating disorders, like suicide or terrorism, are issues that must be covered in a careful and responsible style in order to avoid unwittingly glamorizing or promoting copycats to experiment with these life-threatening behaviors.
In its guidelines to responsible coverage, NEDA indicates not be concentrated on graphic images of people in recovery and not focusing on numbers( i.e. caloric intake and weight ). It’s assumed that focusing on the perceived attractiveness of the subject is similarly frowned upon.
On Reddit, commenters appeared incredibly supportive of lucyffer. Many stated that they are struggling with eating disorders and find her post inspirational. However, a few mentioned that commenting on her body may not be helpful.
It is sometimes triggering for people to hear others praise their body, especially with using words like perfect, because the person hears that and believes that they have to achieve perfection to get kudo, wrote user smearfear, who claims that they too are in recovery from an eating disorder. Even hearing that you seem healthy can be triggering, because to a person with an ED it translates as fat or not sick enough.
The causes and issues surrounding disordered eating are biological, psychological, and social, and it can be difficult to congratulate person in recovery on their progress without focusing on the very body image issues that added to it in the first place. However, focusing on the hotness of someone in recovery helps no onenot the person or persons in question , not readers, and surely not anyone struggling with body image and feeing issues.
