Covid: Lateral flow tests more accurate than first thought, study finds – BBC News

When the researchers used a new formula for calculating the test’s accuracy, they found LFTs were more than 80% effective at detecting any level of Covid-19 infection and likely to be more than 90% effective at detecting who is most infectious when they use the test.

This is much higher than previously thought, they say, adding that rapid tests are “a very useful public health tool” for stopping the spread of the virus.

Prof Michael Mina, from Harvard School of Public Health, also part of the research team, said the LFTs could “catch nearly everyone who is currently a serious risk to public health” when viral loads are at their peak.

“It is most likely that if someone’s LFT is negative but their PCR is positive, then this is because they are not at peak transmissible stage,” he said.

Black Georgia Students Suspended After Planning Protest

Black students along with white and Hispanic students went to the front office, as requested, to talk to administrators about the protest plans and hand over any flyers promoting it. Students tell CBS46 that they began to argue with administrators about the lack of disciplinary action taken against students using racial slurs.

The Black students say they were suspended. Some white students tell CBS46 they were disruptive and argumentative with administrators but they were not suspended, only Black students, according to the student protestors. By Friday, they joined together to protest outside the school throughout the day, most of them were suspended. Others chose to skip, with the permission and support of their parents.

Students of various ethnicities participated in the demonstration on Friday. Parents and student organizers claim that only Black students were suspended for their involvement.

“All the African Americans they suspended them, and they didn’t suspend them,” Lilyan Huckaby said to CBS46 while pointing toward white and Hispanic students. “They didn’t suspend me and I was yelling and loud. It’s because I’m white,” she said.

A few Black parents told CBS 46 that sheriff’s deputies came to their homes to tell them their children had been suspended. One parent said an officer actually pulled her over while she was driving. Another parent claimed that she complained to the administration about prior racist incidents at the school and nothing has been done about it while all three of her children were suspended for the protest.

Forests falling for cashew monocultures: A ‘repeated mistake’ in Côte d’Ivoire (commentary) (Me: monocultures kill the land and trigger pandemic response via increased bat populations)

  • Savannas and dry forests in vast parts of Côte d’Ivoire are being transformed into orchards of cashew trees, just as large areas of its rainforest have fallen for cocoa.
  • Grown in extensive monocultures, cashew has raised incomes but led to deforestation and incursions into protected forests, as major stakeholders overlook the loss of trees and agro-biodiversity.
  • Pollination and human diets are suffering, too: nature-based approaches like agroforestry are needed to create a diversified landscape that can make cashew sustainable in the long run.

Mixing COVID-19 vaccines for boosters safe, effective, study finds –

Mixing COVID-19 vaccines for booster doses is safe and effective, according to the results of a National Institutes of Health-led study released Wednesday.

This means receiving a booster dose of a vaccine that’s different from the shot type given initially provides enough immunity to protect against the virus and that any serious side effects remain rare, the researchers said.

However, the Moderna and Pfizer-BioNTech vaccines generate a stronger immune system response than Johnson & Johnson, even after two doses of the latter, the data showed.

People who received the Johnson & Johnson vaccine had higher antibody levels after receiving a booster shot made by Moderna or Pfizer-BioNTech compared with those given a booster from Johnson & Johnson, according to the researchers.
