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.

기분 좋은 하루 보내고 계신가요?
오늘은 금요일입니다.
멋진 하루 보내고 계시길 바랍니다!
본격적인 뉴스에 들어가기 전, 짧은 심리학 용어를 하나 소개할게요:
연속 위치 효과(Serial Position Effect).
이 효과는 사람들이 시리즈 중 처음과 마지막 항목을 더 잘 기억하는 경향을 설명합니다.
그래서 저는 늘 이렇게 말하곤 합니다.
"한 주를 강하게 시작하고, 강하게 마무리합시다. 하루는 86,400초입니다. 이 마지막 날을 열정적으로 보내면서 주간을 멋지게 끝냅시다."
보건 뉴스: 미국에서 홍역 발병
미국 여러 주에서 홍역 발병이 발생했습니다.
발병은 텍사스의 한 농촌 카운티에서 시작해 수백 건으로 확산되었고,
뉴멕시코, 오클라호마, 캔자스에서도 확진 사례가 보고되었습니다.
홍역은 세계에서 가장 전염성이 높은 질병 중 하나이며, 백신으로 예방이 가능합니다.
특히 어린아이들에게 위험할 수 있습니다.
노출 후 10~14일 후에 기침, 콧물, 인후통, 발열, 발진 등이 나타납니다.
홍역 백신은 1960년대에 개발되어, 2000년에 미국 내에서 박멸되었다고 선언되었습니다.
일반적으로 CDC는 12~15개월 사이에 1차, 4~6세 사이에 2차 접종을 권장합니다.
그러나 세계 여러 나라에서는 여전히 박멸되지 않았고,
저조한 백신 접종률과 외부 유입 사례로 인해 미국에서도 다시 발생할 수 있습니다.
현재 지역 보건 당국은 바이러스가 고위험 지역과 인구로 확산될 수 있다며 우려하고 있습니다.
로버트 F. 케네디 주니어 보건복지부 장관은 대중에게 홍역 백신 접종을 촉구했습니다.
홍역은 왜 그렇게 전염성이 강한가?
**닥터 산제이 굽타(Dr. Sanjay Gupta)**가 설명합니다:
- 홍역은 기침, 재채기, 심지어 숨쉬기만으로도 전염됩니다.
- 홍역 바이러스는 공기 중에 오래 남아, 감염자가 방을 떠난 후 2시간 뒤에도 전염이 가능합니다.
- 감염자가 10명 중 9명에게 전염시킬 수 있습니다.
- 증상이 나타나기 전에도 전염될 수 있습니다.
따라서 **높은 백신 접종률(95%)**을 유지해야 지역사회 감염을 막을 수 있습니다.
중동 뉴스: 이스라엘, UN 학교 6곳 폐쇄 명령
이스라엘 정부는 동예루살렘에 있는 UN 운영 학교 6곳을 30일 내에 폐쇄하라고 명령했습니다.
이로 인해 약 800명의 학생이 학업을 이어갈 수 없게 될 위기에 놓였습니다.
이 학교들은 **팔레스타인 난민을 위한 UN 구호기구(UNRWA)**가 운영해왔습니다.
이스라엘은 이 단체 소속 일부 직원이 2023년 10월 7일 이스라엘 공격에 가담했다고 주장했으나, UN은 이를 부인했습니다.
전쟁이 계속되는 가자지구에서는 학교 건물의 70% 이상이 파괴되었고,
**대학교의 25%**가 파괴되었습니다.
현재 약 80만 명의 학생이 1년 넘게 정규 수업을 받지 못하고 있습니다.
이스라엘은 가자 국경 지역 약 16%를 **완충 지대(buffer zone)**로 만들었으며,
이 지역에서 팔레스타인인들이 사살되는 사건도 발생하고 있습니다.
깜짝 퀴즈: 세계 최초 심장 박동기 실험 동물은?
정답: 개(dog)
1952년 토론토 대학 연구팀이 개를 대상으로 최초의 외부 전자 심장 박동기 실험에 성공했습니다.
세계에서 가장 작은 심장 박동기 개발
오늘의 10/10 뉴스는
참깨(seed) 크기만 한 세계에서 가장 작은 심장 박동기입니다.
노스웨스턴 대학(Northwestern University) 연구진이 개발했으며,
주사기 끝에 들어갈 만큼 작아 수술 없이 주입할 수 있습니다.
- 이 심장 박동기는 피부에 부착하는 작은 패치와 함께 작동합니다.
- 이상 심장 박동이 감지되면 빛이 발사되어 심장에 전기 자극을 보냅니다.
- 특히 선천성 심장 결함을 가진 신생아 치료에 유용할 것으로 기대됩니다.
- 이 장치는 6~9개월 후 자연 분해됩니다.
현재는 실험 단계지만,
미래에는 수많은 아기 생명을 살리는 데 큰 역할을 할 수 있습니다.
