Camels vs. superbugs

Antimicrobial resistance is listed among the top 10 biggest threats to humanity by the World Health Organization. And the most prevalent is drug-resistant bacteria.

But help might be on the way from the dromedary camel.

A new study published in Frontiers in Immunology discovered three teeny infection-fighting molecules called peptides in camel blood.

These peptides can be considered microscopic guards. Two of the three packed a lethal punch against dangerous bacteria that include MRSA and resistant strains of klebsiella.

They are successful by effectively punching holes in bacteria resulting in cell leakage and ultimate collapse.

What’s the catch? Before medical use, further tweaks are required as one of the peptides can damage human red blood cells at increased doses.

The findings, however, suggest that camels that are naturally built to survive harsh desert climates may provide high-powered tools that could be a catalyst for future antibiotics.

Arctic plants make an epic comeback

Sealing Arctic plants in ice all winter might seem redundant, but researchers in Svalbard, Norway, did it anyway over five years.

Over five winters, the research team iced the plants and then slowly warmed it in the spring and summer months to observe the impact of slow warming on the tundra.

The slowly warmed plants grew sluggishly in spring.

The good news, though: They did eventually catch up.

However, the plants that had been covered in ice also often failed to flower, sometimes producing half as many flowers as those not iced over the winter. Fewer flowers equals lower reproduction.

The research, published in the Journal of Ecology concluded that while Arctic plants are incredibly resilient, the icy winter that results from Arctic warming comes at a cost and could reshape the tundra.
