LONDON — Since the start of the coronavirus pandemic, the U.S. has been keeping a close eye on the U.K.
From its initial response to Covid-19 (questioned by many), to its much-praised immunization program and world-class research, all have helped inform how the U.S. — which faced its first major Covid outbreak after Britain — has reacted.
Both strains have proved to be far more transmissible than the original coronavirus that first emerged in China in late 2019. The World Health Organization now predicts that the delta variant — which has already spread to more than 80 countries — will become the dominant strain of the disease worldwide.
Given the U.K.’s experience of both strains at an earlier stage than many other countries, it is now being seen as something of a “test case” for what could happen in the U.S.
Delta ‘greatest threat’ to U.S.
The first thing to note is how quickly the delta variant spread across the U.K.
In a relatively short amount of time, the strain supplanted the alpha variant to become dominant in the country (in mid-June delta was responsible for 90% of all infections, a government study showed) — and this happened despite the U.K.’s advanced vaccination rate.
Meanwhile, cases attributed to the delta strain now make up around 20% of newly diagnosed cases in the U.S. according to White House chief medical advisor Dr. Anthony Fauci.
Fauci warned last week that the delta variant is set to become the dominant Covid strain in the country in a matter of weeks, citing the U.K. as precedent. “It just exploded in the U.K. It went from a minor variant to now more than 90% of the isolates in the U.K.,” Fauci said on NBC’s “TODAY” show.
He said the variant has a doubling time of about two weeks…

Tiny nets woven from DNA strands can ensnare the spike protein of the virus that causes COVID-19, lighting up the virus for a fast-yet-sensitive diagnostic test—and also impeding the virus from infecting cells, opening [...]
Roughly two decades ago, a strategy called optogenetics emerged to control brain activity with lasers. It uses viruses to insert genes into cells that make them sensitive to light. Optogenetics has revolutionized neuroscience by giving researchers [...]
Shigella bacteria, which causes Shigellosis, is the primary cause of bacterial diarrhea and diarrheal death among juveniles under five years of age. Because of the antibiotic resistance of Shigella strains, no commercial vaccines are available to date. [...]
Scientists have built microscopic robots equipped with electronic “brains” that are capable of walking autonomously. A team from Cornell University in the US developed the solar-powered bots as part of research into a new generation of [...]

High-grade serous ovarian cancer (HGSOC) is among the deadliest human cancers and its prognosis remains extremely poor. An article published in Advanced Science explored the self-therapeutic properties of gold nanoparticles to identify a molecular axis that [...]
Antimicrobial peptides (AMPs) have a broad spectrum of antimicrobial activity and lyse microbial cells by interaction with biomembranes, offering great potential in designing new therapeutics. The antimicrobial resistance (AMR) caused due to overuse of [...]
Tumor cells are notoriously good at evading the human immune system; they put up physical walls, wear disguises and handcuff the immune system with molecular tricks. Now, UC San Francisco researchers have developed a [...]
Hyperspectral microscopy is an advanced visualization technique that combines hyperspectral imaging with state-of-the-art optics and computer software to enable rapid identification of nanomaterials. Since hyperspectral datacubes are large, their acquisition is complicated and time-consuming. [...]
Malignant brain tumors are cancerous growth in the brain with the possibility of spreading to other parts of the central nervous system (CNS). Brain tumors are highly invasive and have devastating consequences, poor prognosis, [...]
