Corneal transplantation surgery: AI for an eye
Many consider our eyes to be the windows to the soul. Yet the cornea, the panes of these windows, sometimes need significant repair. Friso Heslinga, PhD, created artificial intelligence models to support surgeons in one of the oldest and most common transplantation procedures.

AI uses ‘selfies’ to detect heart disease
Sending a “selfie” to the doctor could be a cheap and simple way of detecting heart disease, according to the authors of a new study. The study is the first to show that it’s possible to use a deep learning computer algorithm to detect coronary artery disease (CAD) by analysing four photographs of a person’s face. Although the algorithm needs to be developed further and tested in larger…

Nose cells identified as likely coronavirus entry points
Two specific cell types in the nose have been identified as likely initial infection points for COVID-19 coronavirus. Scientists discovered that goblet and ciliated cells in the nose have high levels of the entry proteins that the COVID-19 virus uses to get into our cells. The identification of these cells by researchers from the Wellcome Sanger Institute, University Medical Centre Groningen,…

Cornea restoration: Scientists develop physical biomarker
Our eyes – considered by many to be the windows to the soul – need constant care, and as we age, they sometimes also need significant repair. The panes of these windows – the corneas – are transparent tissues that have been the focus of some of the oldest and most common transplantation surgeries. Now thanks to researchers in Kyoto, some such transplants may become even safer. The team,…

FDA approves first targeted therapy for metastatic bladder cancer
The U.S. Food and Drug Administration (FDA) granted accelerated approval to Balversa (erdafitinib), a treatment for adult patients with locally advanced or metastatic bladder cancer that has a type of susceptible genetic alteration known as FGFR3 or FGFR2, and that has progressed during or following prior platinum-containing chemotherapy. Patients should be selected for therapy with Balversa…

Will nanotechnology give us infrared vision?
Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published in the journal Cell. A single injection of nanoparticles in the mice’s eyes bestowed infrared vision for up to 10 weeks with minimal side effects, allowing them to see infrared light even during the day and with enough specificity to distinguish between different…

FDA approves first artificial iris
The U.S. Food and Drug Administration approved the first stand-alone prosthetic iris in the United States, a surgically implanted device to treat adults and children whose iris is completely missing or damaged due to a congenital condition called aniridia or other damage to the eye. The iris is made of thin, foldable medical-grade silicone and is custom-sized and colored for each individual…

Technique generates human neural stem cells
Tufts University researchers have discovered a new technique for generating rapidly-differentiating human neural stem cells for use in a variety of tissue engineering applications, including a three-dimensional model of the human brain, according to a paper published in Stem Cell Reports. The work could pave the way for experiments that engineer other innervated tissues, such as the skin and…

Evidence of Zika virus found in tears
Researchers have found that Zika virus can live in eyes and have identified genetic material from the virus in tears, according to a study from Washington University School of Medicine in St. Louis. The research, in mice, helps explain why some Zika patients develop eye disease, including a condition known as uveitis that can lead to permanent vision loss.

Human organ donations
You often need the vision of a hypermetropic eagle to find Malta on the world map – even its name fills more space than the representation of the island itself. And yet, in the Eurobarometer 2010 survey, among the recent European Union Member States, the Maltese showed an unusually high level of consent (72%) to organ donation and 77% are willing to donate their own organs, making us a beacon…
