Zhang Yongzhen stages sit-in protest, as government attempts to avoid scrutiny over handling of outbreak

The first Chinese scientist to publish a genomic sequence of the Covid-19 virus, in defiance of government orders, has been staging a sit-in protest after claiming he was locked out of his laboratory.

Zhang Yongzhen, a virologist, said in an online post on Monday that he and his team had been given a sudden eviction notice from their lab, and guards had barred him from entering it over the weekend. The post, published on Weibo, was later deleted, Associated Press (AP) reported.

Research finds hormone that indicates fertility at lower levels in vapers and tobacco smokers

Women should give up vaping if they are hoping to get pregnant, according to a study that suggests it may affect fertility.

In the first research to demonstrate a link between fertility prospects and electronic cigarettes across a large population, analysis of blood samples from 8,340 women revealed that people who vape or smoke tobacco had lower levels of anti-Müllerian hormone (AMH), which indicates how many eggs women have left in their ovaries.

More consensual touch helps ease or buffer against mental and physical complaints, meta-analysis shows

Whether it is a hug from a friend or the caress of a weighted blanket, the sensation of touch appears to bring benefits for the body and mind, researchers say.

The sense of touch is the first to develop in babies and is crucial in allowing us to experience the environment around us as well as communicate. Indeed, the loss of touch from others during the Covid pandemic hit many hard.

Cancer signs could be spotted years before symptoms, says new research institute

Tests that can identify early changes in cells would give doctors more time to offer treatment, say Cambridge researchers

Scientists at a recently opened cancer institute at Cambridge University have begun work that is pinpointing changes in cells many years before they develop into tumours. The research should help design radically new ways to treat cancer, they say.

The Early Cancer Institute – which has just received £11m from an anonymous donor – is focused on finding ways to tackle tumours before they produce symptoms. The research will exploit recent discoveries which have shown that many people develop precancerous conditions that lie in abeyance for long periods.

Cancer charities praise ‘brave’ Princess of Wales for speaking about her diagnosis

Cancer Research UK’s chief executive says high-profile cancer cases such as Catherine’s can help others to seek help early

Cancer charities have praised the Princess of Wales for her “brave” decision to speak out about her cancer diagnosis as a way to encourage others to get their symptoms checked.

In a video message released on Friday, Catherine, 42, spoke of how her condition was discovered after she underwent abdominal surgery in January. In the weeks that followed her procedure, wild rumours flew around her absence and silence – but she said she and her husband, Prince William, had needed time to explain the situation to their three children, George, 10, Charlotte, eight, and Louis, five.

Exclusive: Scientists say people with disease who drink two to four cups a day are less likely to see it return

People with bowel cancer who drink two to four cups of coffee a day are much less likely to see their disease come back, research has found.

People with the illness who consume that amount are also much less likely to die from any cause, the study shows, which suggests coffee helps those diagnosed with the UK’s second biggest cancer killer.

UK researchers find way of diagnosing bowel cancer without biopsies

PET scans can examine entire bowel before and during treatment, avoiding risks associated with taking tissue samples

Researchers in Glasgow have identified a new means of diagnosing and treating bowel cancer with imaging technology, avoiding the need for biopsies.

Biopsies require an invasive procedure with a number of health risks, such as infection, and are limited in what they can capture within a patient’s bowel.

Researchers at Nottingham Trent University hope device used at home will improve tracking of tumours

Scientists are developing a device that fits inside a bra and could monitor whether a breast cancer tumour is growing.

Researchers hope the device will provide a new non-invasive method of detecting tumour growth that patients can use “in the comfort of their own homes”.

Cancer scientist decides to study the tumour that once afflicted his small daughter – and now her work is adding to his project’s success

Elana Simon was 10 years old when she started to experience severe pains in her abdomen. For two years, puzzled doctors put forward diagnoses including lactose intolerance, Crohn’s disease and stress. It was not until 2008 that they pinpointed the real cause. Elana was suffering from fibrolamellar carcinoma (FLC), a rare, usually lethal, form of liver cancer.

“In a way, it was comforting to have a word for what was wrong with me after so much confusion about my condition,” Elana told the Observer. “Pre-diagnosis, my life was a mixture of discomfort and fear. Now I had something to focus on.”

A drug that could improve the quality of life of hundreds of women with womb cancer will be rolled out on the NHS across England from Tuesday.

Dostarlimab, also known as Jemperli, is an immunotherapy that works by attracting specific proteins on the surface of cancer cells to help the immune system attack them.

Team at Imperial College London say techniques could be used to flag warning signs during surgery

It is a high-stakes scenario for any surgeon: a 65-year-old male patient with a high BMI and a heart condition is undergoing emergency surgery for a perforated appendix.

An internal bleed has been detected, an anaesthetics monitor is malfunctioning and various bleepers are sounding – before an urgent call comes in about an ectopic pregnancy on another ward.

Researchers think undercounting goes beyond overloaded health systems to a lack of awareness of Covid and low levels of testing

The Covid death toll in the US is likely at least 16% higher than the official tally, according to a new study, and researchers believe the cause of the undercounting goes beyond overloaded health systems to a lack of awareness of Covid and low levels of testing.

The second year of the pandemic also had nearly as many uncounted excess deaths as the first, the study found.

Scientists have discovered a jab that could prevent rheumatoid arthritis (RA), a development experts say could offer hope to millions at risk of the disease.

RA is a chronic disease that causes inflammation in the body and triggers pain in the joints. About 18 million people globally are affected by the condition, which can lead to heart, lung or nervous system problems, according to the World Health Organization.

Charities say deaths will be prevented if ‘sponge on a string’ test is widely adopted

A test that can detect oesophageal cancer at an earlier stage than current methods should be made more widely available to prevent deaths, charities have said.

The capsule sponge test, previously known as Cytosponge, involves a patient swallowing a dissolvable pill on a string. The pill then releases a sponge which collects cells from the oesophagus as it is retrieved.

Vets should limit the use of flea treatments containing pesticides on dogs and cats, scientists have said, after a study revealed the vast amount of toxic substances in them that end up in rivers.

Pet owners using these flea treatments risk contaminating their hands with fipronil and imidacloprid, two insecticides, for at least 28 days after the treatment has been applied, according to research by the University of Sussex and Imperial College London.

Increase in cardiorespiratory levels of 3% annually found to be beneficial, Swedish research suggests

Men can reduce their risk of prostate cancer by as much as 35% by doing a little more jogging, cycling or swimming, a study suggests.

Boosting cardiorespiratory fitness by only 3% over the course of a year was linked to a much lower chance of developing the disease. The findings prompted the researchers to encourage men to boost their fitness levels to help cut their prostate cancer risk.
