Researchers have discovered a key molecule that allows cancer stem cells to bypass the body’s natural immune defenses, spurring the growth and spread of head and neck squamous cell cancers. Their study, conducted in mice, also demonstrates that inhibiting this molecule derails cancer progression and helps eliminate these stem cells. The findings could help pave the way for more effective targeted treatments for this highly invasive type of cancer, which is characterized by frequent resistance to therapies, rapid metastasis and a high mortality rate.

Over 400 common disinfectants currently in use could be made safer for people and the environment and could better fight the COVID-19 virus with the simple application of UVC light, a new study shows. Researchers discovered that the chemical, benzalkonium chloride’s (BAK) toxicity could be fully neutralized using ultraviolet light (UVC) when tested on cultured human corneal cells.

A team of researchers has developed a device that offers a quicker and less invasive way to seal tears and holes in blood vessels, using an electrically-activated glue patch applied via a minimally invasive balloon catheter. This device could eventually replace the need for open or keyhole surgery to patch up or stitch together internal blood vessel defects.

Researchers have identified how natural human antibodies can block malaria parasites from entering red blood cells, potentially indicating how new protective therapies could be developed against this globally significant disease. The research provides greater insight into how antibodies block the entry of Plasmodium vivax malaria parasites into young red blood cells called reticulocytes. It builds on an earlier discovery that the P. vivax latches onto the transferrin receptor 1 (TfR1) to enter cells.

New research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease. The study investigated whether people who regularly ate higher quantities of nitrate-rich vegetables, such as leafy greens and beetroot, had lower blood pressure, and it also examined whether these same people were less likely to be diagnosed with heart disease many years later.

Researchers are looking to a future someday in which doctors can hit a button to print out a scaffold on their 3D printers and create custom-made replacement skin, cartilage, or other tissue for their patients. The researchers have developed a unique scaffolding material for engineered tissues that can be fine-tuned for the tricky business of growing natural tissue.

Next-generation gene sequencing (NGS) technologies —in which millions of DNA molecules are simultaneously but individually analyzed— theoretically provide researchers and clinicians the ability to noninvasively identify mutations in the blood stream. Identifying such mutations enables earlier diagnosis of cancer and can inform treatment decisions. Researchers developed a new technology to overcome the inefficiencies and high error rates common among next-generation sequencing techniques that have previously limited their clinical application.
To correct for these sequencing errors, the research team developed SaferSeqS (Safer Sequencing System), a major improvement to widely used technologies based on a previous technology called SafeSeqS (Safe Sequencing System) that the investigators invented a decade ago. The new SaferSeqS technology detects rare mutations in blood in a highly efficient manner and reduces the error rate of commonly used technologies for evaluating mutations in the blood more than 100-fold.

A team researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.

People who clock six to seven hours of sleep a night had the lowest chance of dying from a heart attack or stroke when compared with those who got less or more sleep, according to a study. This trend remained true even after the research team accounted for other known conditions or risk factors for heart disease or stroke.

Colorectal cancer diagnoses have increased among people under age 50 in recent years, and researchers are seeking reasons why. A new study has found a link between drinking sugar-sweetened beverages and an increased risk of developing colorectal cancer in women under age 50. The findings suggest that heavy consumption of sugary drinks during adolescence (ages 13 to 18) and adulthood can increase the disease risk.

New research suggests that students learning remotely become night owls but do not sleep more despite the time saved commuting, working or attending social events. The study compared self-reported data on sleep habits from 80 students enrolled in a 2020 summer session course at Simon Fraser University with data collected from 450 students enrolled in the same course during previous summer semesters.
