A look at the 'marijuana' receptor

The study provides a three-dimensional image of cannabinoid receptor 1, which is found to be embedded in the surface of many nerve cells. This discovery could explain how pain medications meant to mimic cannabis use without the 'high' can cause unintended side effects.

How snakes lost a blueprint for making limbs

Researchers found a genetic mutation responsible for the loss of limb formation instructions in snakes, which are unable to form limbs. By restoring the missing DNA sequence in mice, scientists demonstrated that snakes' inability to form limbs is due to a critical stretch of DNA involved in limb growth.

Cell softness predicts corneal transplant success

A study found that corneal cells' softness indicates their potential for stem-like activity, enabling rapid and cost-effective enrichment of limbal stem cells. This biomarker could improve clinical success rates for corneal transplant patients with naturally low limbal stem cell percentages.

A short jump from single-celled ancestors to animals

Researchers studied a single-celled amoeba called Capsaspora owczarzaki and found it uses the same protein-regulating tools as multicellular animals to control cell differentiation over time. This suggests that the single-celled ancestor of all animals likely possessed these systems and was more complex than previously thought.

That jumping spider can hear you from across the room

Researchers discovered that jumping spiders can detect sounds at distances of over three meters, a finding that changes scientists' understanding of the world spiders live in. The spiders' hearing is most sensitive to frequencies associated with the wingbeats of parasitoid wasp enemies, prompting a startle response.

Astroglia zip the 2 halves of the brain together

A study published in Cell Reports reveals that astroglial cells play a crucial role in forming the corpus callosum, a bridge-like structure connecting the two hemispheres of the brain. Without this cellular support, callosal agenesis occurs, affecting 1 in 4,000 people and leading to developmental disorders.

Mix and match microbes to make probiotics last

Researchers found that a specific strain of Bifidobacterium longum AH1206 can establish itself in the human gut and remain there for up to 6 months. The study suggests that individualized features of the resident microbiome play a crucial role in the persistence of this strain, enabling personalized probiotic treatments.
