WhatsApp is rolling out username reservations globally, letting users reserve unique names before the privacy feature launches later this year.

I show how the time dilation derived in special relativity by assuming an abstract concept of malleable time, can be derived in a more mechanistic manner by assuming that the cosmos is like a simulation \& time is a processing delay.

I had this idea while playing minecraft with my son — every time I approached a large villager-town the PC slowed down and I thought \.

Unlike some other spiders that camouflage themselves with drab colors and sticklike appendages, the jumping spider Siler collingwoodi disguises itself by the way it moves. The bright blue and orange arachnid—a pea-size animal native to China and Japan—crawls like an ant, according to a new study.

In a side-by-side comparison, researchers found that S. collingwoodi spiders copied the movements of multiple spikey, aggressive species of ants. The spiders walked at a similar pace, bobbed their abdomens like the ants did, and elevated their first pair of legs when they walked, imitating antennae.

Melatonin reduced infection-related inflammation in human fetal membranes in an ex vivo model. The study suggests that this effect works partly through melatonin receptors and by suppressing the TLR4/MyD88/NF-κB pathway.

Nasal commensal viruses may worsen allergic rhinitis by activating type I IFN-linked neutrophils and NET formation. Ribavirin reduced nasal viral abundance and improved symptoms in mice and in a small phase 2 trial.

In the originally published version of this article, there was an error with Figure 3H that occurred during the final preparation of the manuscript, where some of the cellular images were displayed as black panels. The figure has been replaced with a corrected Figure 3H where the cellular images are now visible.
