Researchers from the Universities of Cambridge and Cape Town may have found a solution to the mystery of how phosphorus came to be an essential component of life on Earth by recreating prehistoric seawater containing the element in a laboratory.

Their findings, which were published in the journal Nature Communications.

Vaccines that target cancer could be available before the end of the decade, according to the husband and wife team behind one of the most successful Covid vaccines of the pandemic.

Uğur Şahin and Özlem Türeci, who co-founded BioNTech, the German firm that partnered with Pfizer to manufacture a revolutionary mRNA Covid vaccine, said they had made breakthroughs that fuelled their optimism for cancer vaccines in the coming years.

Tumors escape killing by the immune system through generating transient spatial cell-in-cell structures that are impenetrable to cytotoxic compounds including lytic granules and chemotherapy.

The recently identified, globally predominant SARS-CoV-2 Omicron variant (BA.1) is highly transmissible, even in fully vaccinated individuals, and causes attenuated disease compared with other major viral variants recognized to date^{1 – 7}. The Omicron spike (S) protein, with an unusually large number of mutations, is considered the major driver of these phenotypes^3,8. We generated chimeric recombinant SARS-CoV-2 encoding the S gene of Omicron in the backbone of an ancestral SARS-CoV-2 isolate and compared this virus with the naturally circulating Omicron variant. The Omicron S-bearing virus robustly escapes vaccine-induced humoral immunity, mainly due to mutations in the receptor-binding motif (RBM), yet unlike naturally occurring Omicron, efficiently replicates in cell lines and primary-like distal lung cells. In K18-hACE2 mice, while Omicron causes mild, non-fatal infection, the Omicron S-carrying virus inflicts severe disease with a mortality rate of 80%. This indicates that while the vaccine escape of Omicron is defined by mutations in S, major determinants of viral pathogenicity reside outside of S.

The authors have declared no competing interest.

The husband-and-wife team who co-founded BioNTech, the biotechnology company that partnered with Pfizer to develop an effective messenger-RNA (mRNA) shot against COVID-19, has predicted that a cancer vaccine could be widely available within the next decade.

“Yes, we feel that a cure for cancer, or to changing cancer patients’ lives, is in our grasp,” said Professor Ozlem Tureci during an interview on BBC’s ‘Sunday with Laura Kuenssberg’.

The cancer vaccine, which would build upon breakthroughs achieved by the scientists during the development of the COVID-19 shot, may be widely available within just eight years, said Professor Ugur Sahin.

Summary: Proteins associated with motor neuron disease, or ALS are present in the gut many years before disease pathologies can be found in the brain. A stool sample or gut biopsy could help identify the presence of MND-associated proteins years before symptoms appear.

The same proteins thought to contribute to motor neuron disease can be found in the gut many years before any brain symptoms occur, a new study by the University of Aberdeen has found.

Cleveland Clinic researchers have identified a common diabetes medication, metformin, as a possible treatment for atrial fibrillation.

The study, published in Cell Reports Medicine, built on ongoing collaborative Cleveland Clinic research to support further investigation into metformin as a drug repurposing candidate. Researchers used advanced computation and genetic sequencing to determine that metformin’s targets overlap significantly with genes dysregulated in atrial fibrillation.

Finding drugs or procedures to treat atrial fibrillation is difficult because of potential serious side effects. There is a significant need for new treatments for atrial fibrillation as there have been no new drugs approved in more than a decade.

The liver is known for its ability to regenerate. It can completely regrow itself even after two-thirds of its mass has been surgically removed. But damage from medications, alcohol abuse, or obesity can eventually cause the liver to fail.

Currently, the only effective treatment for end-stage liver disease is transplantation.

However, there is a dearth of organs available for transplantation. Patients may have to wait from 30 days to over 5 years to receive a liver for transplant in the US. Of the over 11,600 patients on the waiting list to receive a liver transplant in 2021, only a little over 9,200 received one.
