time after the market closes when an investor can buy and sell securities outside regular trading hours. Both the New York Stock Exchange (NYSE) and the Nasdaq normally operate between 9:30 a.m. and 4:00 p.m. Eastern Time. Trades during the after-hours session can be completed anytime between 4:00 p.m. and 8:00 p.m. Eastern Standard Time.1?2?
In these extended trading sessions, electronic communication networks (ECNs) match potential buyers and sellers without using a traditional stock exchange. The trading volume during the after-hours trading session tends to be fairly thin. That's because there are usually very few active traders during this time period. This can change, though, with volume spiking if there's big economic news or something breaks about a company.
Just like volume, traders can expect wider spreads—the difference between the bid and ask prices—after the market closes

Regardless of opening price if the demand for shares are there the price will rise.....
Must have expected news sooner (maybe) to get the Twitter site up in July but only announced it today with the first tweet.
News imminent I feel....

Excerpt:
To give an idea of how effective Affimer binders are, a great example of an Affimer molecule application is the recent Affidx COVID-19 diagnostic test. This is a lateral flow device (LFD), where a sample from a nasal swab is mixed with buffer and applied to a paper strip. The liquid travels across the strip, where a line of COVID-19 virus-binding Affimer proteins await. If the virus is present, the Affimer molecules bind and immobilise the particles. A detection antibody then binds, creating a visual line for the user. These highly-specific Affimer molecules, which led to one of the most sensitive LFDs in the world being developed, were found via the panning method described above. From start-to-finish, the optimum binders were found in just 4 weeks
This ability of Affimer proteins to be rapidly developed, coupled with their list of antibody-beating properties, make them ideal tools for a huge range of diagnostic applications. However, work is on-going to also exploit their properties for therapeutic applications. For example, a type of anticancer drug known as a ‘checkpoint inhibitor’ is currently in development, as-well-as a recent Nature publication on ‘druggable pockets’ that are notoriously difficult to identify.

The delta variant of the coronavirus has been surging through the United States as of late, leading to an uptick of cases after a calm past few months.
With such a dramatic shift, there might be some people — fully vaccinated or unvaccinated — seeking out COVID-19 tests. But is there a COVID-19 test for the delta variant?
Is there a specific COVID-19 test for the delta variant? What you need to know
The delta variant is surging. Is there a specific test for it?
Is there a delta variant COVID-19 test?
Current COVID-19 tests can’t always detect the delta variant. The delta variant “carries distinctive biological markers that some among the dozens of commercially available COVID tests from academic institutes and medical giants may not be able to sense,” according to Fortune.
Avacta, a medical firm, has been building a test to detect the delta variant. And the U.K. seems to be building technology to keep an eye on the delta variant through specific tests.
How do officials discover the variants, then?
However, the Centers for Disease Control and Prevention can look at specific cases of the coronavirus through genetic sequencing. But there isn’t a specific test that will tell you if you have the delta variant.
According to the CDC, sequenced cases are COVID-19 cases that the CDC has examined to review their genetic makeup and code. This is how variants of the virus are often discovered.

Introduction
As we exit lockdown in line with the government’s roadmap, we will need to remain vigilant against potential COVID-19 outbreaks.
As the market for private testing grows, it is important that consumers have confidence the COVID-19 detection tests they use give reliable and accurate results. COVID-19 remains a notifiable disease and it is important that all tests attain required performance standards.
It would undermine current public health goals if people used poor quality tests that give them a false sense of security. In the case of a false negative, this could see an infected individual unknowingly spread the virus. Conversely false positives could require business to close and people to isolate unnecessarily.

Hospital patients in Wales may be able to have more visitors as new visiting guidelines come into force on Monday.
The new guidelines will give health boards the option to use lateral flow tests or point-of-care testing to allow hospital visiting, including in maternity units.

*Dame Rachel de Souza says there is an urgent need for children to get back to normal
*Schools minister Nick Gibb says regular tests of children in contact with those who have tested positive could replace isolation
He says a trial of daily contact testing as an alternative to self-isolation ends tomorrow and the data will be examined
*Former schools catch up tsar Sir Kevan Collins, who quit over a lack of funding for pandemic recovery plans, is speaking to MPs
He tells the Education Select Committee more vulnerable pupils have had a "very difficult time" during the pandemic
