The first results from Juno’s brush with Jupiter reveal swarms of cyclones, massive ammonia plumes and complex interactions between a turbulent magnetic field and powerful streams of electrons. The findings are published today in Science and Geophysical Research Letters.
The Juno team is still sifting through the massive piles of data the probe is sending back from the gas giant. Since arriv ...read more

Cowpea seed beetle sex is complicated.
During copulation, the male seed beetle, Callosobruchus maculatus, uses his sharp, spiky penis to damage females’ reproductive tract while depositing sperm. All the while, the female vigorously kicks at her suitor—it hurts! As studies have shown, males with longer, harmful penis spikes enjoy more reproductive success, to the detriment of their partner’s health.
But the process of evolution ha ...read more

Just nine years after its official opening, the Svalbard Global Seed Vault in Norway is undergoing renovations to protect it from climate change.
The work was prompted by accidental flooding that took place last week, as melting permafrost seeped into the vault’s access corridor. While the seeds were in no danger, the flooding is nevertheless a worrying sign at a facility meant to en ...read more

A trek to base camp at Mount Everest will leave you short of breath in a hurry.
A push to the summit begins in thin air, 17,000 feet above sea level — higher than any peak in the Rocky Mountains. Once you reach the “Death Zone,” above 26,000 feet, oxygen levels drop to a third of what they are at sea level. Few climbers reach the summit, which rises 29,029 feet above sea level, without bottled oxygen.
To acclimate their ...read more
Brain responses to emotion stimuli are highly variable even within the same individual, and this could be a problem for researchers who seek to use these responses as biomarkers to help diagnose and treat disorders such as depression.
That’s according to a new paper in Neuroimage, from University College London neuroscientists Camilla Nord and colleagues.
Nord et al. had 29 volunteers perform three tasks during fMRI scanning. All of the tasks involved pictures of emotional faces, which ar ...read more

In the last few decades, scientists have come to appreciate the incredible creatures living on the reefs that lie just below conventional diving limits in what is called the mesophotic zone. These incredible biodiversity hotspots are home to more endemic species than shallower reefs, and conservationists are hopeful they may serve as refuges—pockets of relatively pristine habitat out of ...read more

Flamingos are striking not only for their brilliant pink plumes, but for how they often stand on a single slender leg, even when asleep.
Now scientists find that standing on one leg may counter-intuitively require less effort for flamingos than standing on two. It’s a finding that could help lead to more stable legged robots and better prosthetic legs.

No matter how flamboyant your shower curtain mold is, it couldn’t have competed with the fungus that won this year’s Agar Art contest.
This is the third year the American Society for Microbiology has run the contest, asking for “works that are at their core an organism(s) growing on agar.” The artwork can be any kind of microbe colonizing any size or shape of petri dish. This year&rsq ...read more
