Degrading a key cancer cell-surface protein to invigorate immune attack on tumors

One powerful way cancer cells defend against tumor-killing immune cells is to load up their cell surface with a protein known as PD-L1. Now a team of researchers has identified a method to degrade tumor cell-surface PD-L1, thereby making tumors susceptible to immune attack.

The secret to a longer lifespan? Gene regulation holds a clue

Researchers investigated genes connected to lifespan. Their research uncovered specific characteristics of these genes and revealed that two regulatory systems controlling gene expression -- circadian and pluripotency networks -- are critical to longevity. The findings have implications both in understanding how longevity evolves and in providing new targets to combat aging and age-related diseases.

Oil spill remediation: Research confirms effectiveness of oil dispersants

Chemical dispersants are some of the best tools to clean up after an oil spill. However, scientists do not fully understand how well they work. A new study validated their efficacy in order to better prepare for the next disaster.

Your liver is just under three years old

The liver has a unique ability to regenerate after damage. However, it was unknown whether this ability decreases as we age. Scientists have now used a technique known as retrospective radiocarbon birth dating to determine the age of the human liver. They showed that no matter the person's age, the liver is always on average less than three years old. The results demonstrate that aging does not influence liver renewal, making the liver an organ that generally replaces its cells equally well in young and old people.

Electrical pulses to the back of the neck found to restore breathing after drug use

Breathing difficulties are the main cause of death following opioid use. In the UK, the number of adults entering treatment for opioid use was 140,863 in 2020/211 and opioid use remains a significant cause of premature death, contributing to 3,726 drug-related deaths last year. Opioid misuse causes death by supressing respiratory activity. New research points to a novel treatment for respiratory depression associated with opioid use that administers electrical pulses to the back of the neck, helping patients regain respiratory control following high dosage opioid use. This could offer an alternative to pharmacological treatments, which can cause withdrawal symptoms, heart problems and can negatively affect the central nervous system.
