A Maryland man has lived for three days with a pig heart beating inside his chest. The surgery, at the University of Maryland Medical Center, marks the first time a gene-edited pig has been used as an organ donor.

A 57-year-old Maryland man is doing well three days after receiving a genetically modified pig heart in a first-of-its-kind transplant surgery, University of Maryland Medicine said in a news release Monday.

Immune cells in the bodies of mice have been temporarily reprogrammed to repair damaged hearts by removing scar tissue, thanks to the technology used in the mRNA coronavirus vaccines. “After you give the treatment, the scar goes away,” says Haig Aghajanian at the University of Pennsylvania.

Inspired by water-walking insects, scientists have built liquid robots that work autonomously and continuously without the need for electrical inputs, transporting chemicals back and forth while partially submerged in solution.

Female patients found to have 15% more chance of a bad outcome than if procedure was performed by a woman

A whistleblower in the Canadian province of New Brunswick has warned that a progressive neurological illness that has baffled experts for more than two years appears to be affecting a growing number of young people and causing swift cognitive decline among some of the afflicted.

For more than a year, Victoria Gray's life had been transformed. Gone were the sudden attacks of horrible pain that had tortured her all her life. Gone was the devastating fatigue that had left her helpless to care for herself or her kids. Gone were the nightmarish nights in the emergency room getting blood transfusions and powerful pain medication.

Molecules in tarantula venom could be used as an alternative to opioid pain killers for people seeking chronic pain relief.

Vaccine protection against COVID-19 wanes more quickly among cancer patients, but boosters rapidly bolster their antibody levels, Israeli research has found. The study supports the case for giving cancer patients third vaccine doses in countries where they have only received two, according to author Dr. Hagai Ligumsky. And it encourages the rollout of fourth shots for this demographic in countries like Israel that already gave third shots, he added.

Of late, we’ve been getting used to shortages of things we’ve previously taken for granted, like petrol, gas, toilet rolls, HGV drivers and seasonal labour. Could it be that we’re about to add a new item to that list: antibiotics?

Barcelona’s Clínic Hospital announces hopeful results for people with multiple myeloma. Developed through the public system, the cost is lower than commercially available products.

This summer, Omar Rodriguez, 47, was diagnosed with stage 3 colon cancer. And even though he had surgery to get rid of the tumor, there's a 70 percent possibility that it will return within the next five years.

A Japanese research team said it developed a vaccine to remove so-called zombie cells that accumulate with age and damage nearby cells, causing aging-related diseases including arterial stiffening.

HIV (Human Immunodeficiency Virus) causes AIDS (Acquired Immunodeficiency Syndrome) and this syndrome interferes with the immune system of our body. Slowly, our body’s ability to fight against infections will be suppressed.

Researchers in China have developed a new three-pronged method to fight liver cancer that shows promise in tests in mice. The technique combines drugs and CRISPR-Cas9 gene editing into lipid nanoparticles, then activates them with ultrasound.

An international team of scientists believe they may have found a molecular mechanism behind the extremely rare blood clots linked to adenovirus COVID-19 vaccines. Scientists from Cardiff University and Arizona State University worked with AstraZeneca to investigate vaccine-induced immune thrombotic thrombocytopenia (VITT), also known as thrombosis with thrombocytopenia syndrome (TTS), a life-threatening condition seen in a very small number of people after receiving the Oxford-AstraZeneca or Johnson & Johnson vaccines.

A kidney grown in a genetically altered pig functions normally, scientists reported. The procedure may open the door to a renewable source of desperately needed organs.

Dr Angelique Coetzee, the South African doctor who first spotted the new Covid variant Omicron, says the patients seen so far have had "extremely mild symptoms" - but more time is needed before we know the seriousness of the disease for vulnerable people.

Scientists believe mRNA vaccines – which have played a crucial role in our fight against Covid-19 – could solve a number of health issues for humans.
