We summarize the week's scientific breakthroughs every Thursday.
- Animals
Climate stress may undermine male spiders’ romantic gift giving
Even spider love lives show an effect of climate uncertainty: Stressed males may offer a bit of silk-wrapped junk rather than a tasty insect treat.

Trees are failing to adapt to climate change. Losing fungi partners may be why
Certain fungi give trees nutrients and water, but heat and drought are putting both at risk.
- Ecosystems
New videos reveal the hidden lives of Andean bears
The footage give clues to the range of plants the bears eat and how they mate, information important for conservation.

Here’s how long it would take 100 worms to eat the plastic in one face mask
An experiment reveals that a bio-solution to humans’ microplastics mess is likely to fall short, but could inspire other ways to attack the problem.
- Animals
Ethiopian wolves are the first large carnivores found to slurp nectar
Wolves from three different packs were seen licking red hot poker flowers. That sweet tooth could make them the first known large predator pollinators.
- Neuroscience
Electronic ‘tattoos’ offer an alternative to electrodes for brain monitoring
A standard EEG test requires electrodes that come with pitfalls. A spray-on ink, capable of carrying electrical signals, avoids some of those.
- Animals
Giant hornets have been sighted in Europe for the first time
Four southern giant hornets have turned up in Spain. Similar stingers, known for honeybee attacks, had the Pacific Northwest on edge a few years ago.
- Animals
Videos capture orcas’ tricks for taking down the largest fish on Earth
Citizen science videos document for the first time how orcas coordinate an attack against whale sharks.
- Science & Society
This ‘hidden figure’ of entomology fought for civil rights
Margaret S. Collins, the first Black American female entomologist to earn a Ph.D., overcame sexism and racism to become a termite expert.
- Neuroscience
Like brain cells, kidney cells can form memories
Scientists found memory’s molecular machinery at work in cells outside the nervous system.
- Paleontology
China’s famously rich dinosaur fossil beds get a new origins story
Cave-ins and floods may have buried the Cretaceous creatures of the fossil Jehol Biota rather than volcanic eruptions, a new study claims.
- Health & Medicine
Dengue is classified as an urban disease. Mosquitoes don’t care
Infectious diseases are often labeled “urban” or “rural.” Applying political labels to public health misses who is at risk, experts argue.
