Sensing environmental temperature is crucial for the development and survival of animals. Insects such as fruit flies have evolved a particularly delicate thermosensory system that can discriminate temperature changes within a milli-degree per second. This accurate thermosensation relies on the…

How does coffee affect a sleeping brain?
Caffeine is not only found in coffee, but also in tea, chocolate, energy drinks and many soft drinks, making it one of the most widely consumed psychoactive substances in the world.
In a study published in April in Nature Communications Biology, a team of researchers from Université de…

Unlocking precise composition analysis of nanomedicines
Current regulations for nanomedicines overlook the effects of the different forms of the same element, such as ions, nanoparticles, and aggregates. In a recent study, Japanese researchers developed a new analytical method combining an asymmetric flow field-flow fractionation system and mass…

Findings on the protein that forms loops in the human genome
Cohesin is a protein that forms a ring-shaped complex which wraps and alters the DNA molecule shape. It moves through the DNA and creates specific loops in the genetic material which determine the architecture of the genome and gene expression. Some mutations in the genes of the cohesion complex…

Novel biomarker: Potential to predict and treat skin cancer metastasis
Researchers have identified C5aR1 as a novel biomarker for metastasis risk and poor prognosis in patients with cutaneous squamous cell carcinoma (cSCC), the most common type of metastatic skin cancer. The new study’s findings in The American Journal of Pathology, published by Elsevier, found…

HIV discovery could open door to long-sought cure
University of Virginia School of Medicine scientists have uncovered a key reason why HIV remains so difficult to cure: Their research shows that small changes in the virus affect how quickly or slowly it replicates, and how easily or stubbornly it can reawaken from hiding. These insights bring…

Earlier measles vaccine could help curb global outbreak
The global measles outbreak must trigger an urgent debate into whether a vaccine should be recommended earlier to better protect against the highly contagious disease during infancy, a new review states.
The systematic review, led by Murdoch Children’s Research Institute (MCRI), found…

Genetics and therapy type determine second cancer risk after childhood treatment
Physicians caring for survivors of childhood cancer later in life should be aware that survivors’ genetics, in addition to their lifesaving cancer treatment, contribute to the risk for secondary cancers. This finding comes from scientists at St. Jude Children’s Research Hospital who quantified…

All-in-one model reconstructs complex liver architecture
The liver has a unique structure, especially at the level of individual cells. Hepatocytes, the main liver cells, release bile into tiny channels called bile canaliculi, which drain into the bile duct in the liver periportal region. When this bile drainage system is disrupted, it causes liver…
