Engineers developed a way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells. Their models could help researchers develop and test potential drugs for pancreatic cancer. Studying these organoids could help researchers develop and test new treatments for pancreatic cancer, one of the deadliest types of cancer.

In a surprising new finding in mice, researchers have discovered that many genes linked to human cancer block the body's natural defense against malignancies.

The Delta variant of SARS-CoV-2, the virus that causes COVID-19, is more transmissible than preexisting variants, and it has rapidly become the dominant variant in several countries, including India and the United Kingdom. Some reports suggest that existing COVID-19 vaccines may be less effective in preventing infection with Delta. Can additional booster shots help?

New anti-cancer strategy -- blocking chemicals produced by tumors -- could boost life span, health span Scientists don't really know what kills many cancer patients, but fruit fly research could provide answers. By following flies with tumors up to the point of death, researchers have discovered chemicals produced by tumors that shorten life span apart from the damage done locally to critical organs. This suggests a novel strategy for extending a healthy life span in those with a cancer burden: block the tumor-generated chemicals and the damage they do.

“There is definitely substantial transmission happening in this age group. In fact, the age group we are talking about is the one in which the highest rate of transmission is currently occurring, as far as we can tell,” England’s chief medical officer Chris Whitty said.

In its new travel advisory, the UK said that a traveller will be considered fully vaccinated if they are inoculated with a full dose of the Oxford-AstraZeneca, Pfizer-BioNTech, Moderna, or Janssen vaccines from a relevant public health body in select countries.

According to a recent study from the University of Georgia (UGA) published in Nature's Scientific Reports, probenecid has potent antiviral properties that make the oral medication a prime candidate to combat not only SARS-CoV-2 infection but other common and deadly respiratory viruses.

The latest government report on Adverse Events Following Immunisation (AEFI) with Covid-19 vaccines has found that 61 per cent of the events analysed were causally related to vaccinations. However, none of these was fatal, i.e. resulted in death, the report says. Report comes 7 weeks after meeting by AEFI committee, and 10 weeks after the last report. In the time since, India administered over 48 crore doses.

Mild cognitive impairment (MCI) often precedes the development of Alzheimer’s disease. Functional MRI (fMRI) scans can capture subtle signs of MCI, but they are difficult to interpret. Lithuanian researchers have developed a deep learning algorithm that identified MCI in a small study.

Trial results provide a strong foundation for seeking authorization of the vaccine for children 5 to 11 years old. The clinical trial data of COVID vaccine will be submitted to regulatory authorities for school-aged children before the start of the winter season
