What's up, sunshine?
It's Friday. Friday.
Hope you're having an awesome one
Quick psychology term that I'm going to share with you before we get you your news and head into this weekend
Serial position effect it's a psychological phenomenon describing how people have this tendency to remember the first and last items in a series. uh
They remember those things best
That's why I'm often saying "Let's start this week off, strong let's finish, this week strong. We only have 86,400 seconds in a day, so let's tackle this last day of the week with some enthusiasm and finish this week strong.
"We begin today with health news.
There's an outbreak of measles in multiple states in the United States.
The outbreak began in a rural county in Texas and has now spread to several hundred cases there.
New Mexico, Oklahoma and Kansas have also confirmed cases of measles.
Measles is one of the world's most contagious diseases that is also easily preventable with a vaccine.
The viral infection can be serious for small children.
Symptoms like coughing, runny nose, sore throat, fever and skin rash are slow to appear usually 10 to 14 days after exposure.
The measles vaccine was developed in the 1960s and is so effective that measles was declared fully eradicated in the US in 2000
Under normal circumstances the US Centers for Disease Control or CDC recommends one dose of the vaccine between 12 to 15 months of age and another between 4 and 6 years old.
It's important to note that measles has not been eradicated in many countries around the world and outbreaks can happen because of imported cases and low vaccination rates.
Local officials in states linked to the measles outbreak are now concerned the measles virus could spread into high traffic areas and vulnerable populations.
Because of the contagious nature of the virus and low vaccination rates in some areas of the country experts expect the outbreak could continue to grow.
US Health and Human Services Secretary Robert F kennedy Jr is publicly urging people to get the measles vaccine.
Let's hear from our Dr sanjay Gupta who explains what measles is and why it's so contagious
Measles is one of the most contagious diseases on the planet.
Now like the flu or COVID 19 it can be spread through coughing, sneezing, even breathing, but the thing about the measles virus is that it can also linger longer.
Picture this, if someone had measles and left the room, 2 hours later if someone who was unvaccinated walked in, they would have a 90% chance of getting measles.
2 hours later!
It's also estimated that a person with measles could infect nine out of 10 of their close contacts if their contacts are unvaccinated.
Another reason, it's so contagious that it can spread before symptoms even develop.
That means you can spread it to others days before you start to get sick.
Days before those characteristic red spots appear.
But the key here is vaccination and because measles is so contagious you need a
really high level of vaccination.
We're talking 95% in the community to help keep it at bay.
That's why we see outbreaks occur in pockets of the country where that number has dropped.
Now to news out of the Middle East where Israel has ordered six UN schools in East Jerusalem to close within 30 days.
The closures will mean roughly 800 students there may not be able to finish the school year.
The schools were run by the UN Relief and Works Agency for Palestine refugees which operates schools for Palestinians in Israeli occupied areas.
Israel has accused a handful of employees of that agency in Gaza of participating in the attack on Israelis on October 7th of 2023.
A claim the UN denies
Israel's Ministry of Education is now telling parents to register the students in other schools, but with the war in Gaza continuing the education system for Palestinians in the region is in ruins.
At least 70% of the school buildings there in Gaza have taken direct hits from Israeli air strikes and nearly a quarter of university campuses have been destroyed.
The UN says none of the nearly 800,000 students there have had any formal schooling for more than a year.
Many of those schools were located within large areas of land that Israel seized to
incorporate into what the military has announced as security zones.
Our Jeremy Diamond shows us how the military transformed part of Gazin territory
within about a half of a mile of the Israeli border into rubble.
Inside Gaza swaths of land closest to the Israeli border have been turned into a
Wasteland.
Nearly every building within about a half mile of the border fence has been destroyed and we filmed this footage a year ago while demolitions were still ongoing.
Over time the Israeli military has raised about 22 square miles of Palestinian land creating a buffer zone on about 16% of Gaza's territory.
It is a no-go zone for Palestinians some of whom have been killed after setting foot
inside the unmarked perimeter.
Over the course of the war this one-time economic hub was flattened.
This video which CNN geo-located shows the destruction of Gaza's only Coca-Cola
Factory, but it's not just factories in the town of Huzah, but also hundreds of homes were leveled with a clear zone of destruction, spanning about 1 kilometer from the border.
Residential buildings, greenhouses, sheds, factories you name it, it needs to be flat that's the order a sergeant major who served in Khuzah said.
Except for the UNRWA school and that small water facility, the directive was nothing left.
He is one of a dozen Israeli soldiers who describe the demolitions and enforcement of the buffer zone as breaking the silence of an Israeli watchdog group that verifies and publishes soldiers' testimonials.
The Israeli military did not respond to CNN's request for comment.
More than 6,200 Palestinian buildings have been damaged or destroyed within 1 kilometer of the Gaza border according to satellite analysis including here in Al Burge where homes and acres of farmland were destroyed.
What animal was the first to use an external cardiac pacemaker?
Mouse/ rabbit/ dog/ or cat/ meow
If you said dog, your dog is on the right.
In 1952, doctors at the University of Toronto successfully tested the heart of a dog using an external electronic pacemaker, a medical device that is implanted in millions of people today, helping to stabilize their heartbeat.
Today's story getting a 10 out of 10 goes to a pacemaker so small it can fit on the tip of a needle.
Scientists at Northwestern University say they have developed the world's smallest pacemaker smaller than a grain of rice.
It can be injected into a patient's body without surgery.
Normally the medical device fits in the palm of a hand typically about the size of a
Matchbox.
Our Jacqueline Howard shows us how the device works and the tiniest patients it could one day help.
It's about the same size as a sesame seed.
They're calling this the world's smallest pacemaker.
Engineers at Northwestern University developed the device to be so minuscule that it fits inside the tip of a syringe and it can be injected right into a patient's chest, so no invasive surgeries are needed.
The pacemaker itself is light-sensitive.
It works alongside this small patch stuck to the skin.
When an irregular heartbeat is detected, it flashes.
That light activates electrodes on the pacemaker and then sends electrical impulses to the heart, helping to control and correct the pace of the heartbeats.
While this tiny pacemaker can work with a heart of any size, it might especially benefit newborn babies with congenital heart defects as they recover from serious heart surgeries.
??? of recovery can be daunting, especially for infants who undergo that kind of surgery.
The pacemaker isn't meant to be worn for life.
It will dissolve away for 6 to 9 months completely.
For now, this tiny piece of technology is still an experiment, but one day it could make a big difference for our youngest, tiniest heart patients.
