Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.
New study reveals how competition between algae is transforming the Gulf of Maine
New research shows how rapidly proliferating turf algae are waging 'chemical warfare' to inhibit the recovery of kelp forests along Maine's warming coast.
The scent of death? Worms experience altered fertility and lifespan when exposed to dead counterparts
Research reveals that for C. elegans worms, the presence of dead members of their species has profound behavioral and physiological effects, leading them to more quickly reproduce and shortening their lifespans.
Climate change poses severe threat to bowhead whale habitat
New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent.
Looking to cut calories? Try adding chilies, study suggests
Throwing a little heat on your meal might be an effective strategy for cutting back on calories, according to a new study.
A potential ‘anti-spice’ that could dial down the heat of fiery food
If you've ever regretted ordering a spicy meal, take note: A new study identifying molecules that suppress the heat of chili peppers hints at the possibility of adapting these compounds into an 'anti-spice' condiment for food that's too fiery to eat. The research helps explain differences in chili pepper pungency,...
Shrinking Nemo: Clownfish survive heatwaves by shrinking
Clownfish have been shown to shrink in order to survive heat stress and avoid social conflict, research reveals.
Unlocking the secrets of bat immunity

In contrast to the severe and often fatal disease outcomes these viruses cause in humans, bats generally do not show obvious signs of viral illness following...
Personal space chemistry suppressed by perfume and body lotion indoors
In 2022 a team discovered that high levels of OH radicals can be generated indoors, simply due to the presence of people and ozone. This means: People generate their own oxidation field and change the indoor air chemistry around them within their own personal space. Now, in a follow-up study...
