Hainan Island’s Tea Plants Are Unique Variety of Camellia sinensis: Study
Tea (Camellia sinensis), originating in China over 3,000 years ago, has transitioned from a medicinal herb to a widely consumed beverage. Despite considerable research focusing on tea plants in southwestern China, little attention has been paid to those on Hainan Island. The notable resemblance between Hainan tea and Camellia sinensis var. assamica, alongside the unique
Nanotech Scientists Build on an Insect’s Odd Soccer Ball-Like Excretions to Design Ingenious Camouflage
January 2, 2025 5 min read Artificial versions of nanoscale soccer-ball-like structures called brochosomes might be used to make new forms of military camouflage, self-cleaning surfaces or hydrogen fuel By Ivan Amato edited by Gary Stix Brochosomes.

DECam Zooms in on Antlia Galaxy Cluster
The Antlia galaxy cluster is a group of at least 230 galaxies held together by gravity; this cluster is unusual — unlike most other galaxy clusters, it appears to have no dominant galaxy within it. The Antlia cluster is dominated by two massive elliptical galaxies: NGC 3268 (center) and NGC 3258 (lower right). Image credit:
Researchers Create New Nanosensors of Force
The newly-developed all-optical nanosensors are luminescent nanocrystals that can change intensity and/or color when you push or pull on them; they are probed with light only and therefore allow for fully remote read-outs — no wires or connections are needed; they have 100 times better force sensitivity than the existing nanoparticles that utilize rare-earth ions
Do We Live in a Special Part of the Universe?
December 31, 2024 4 min read According to a tenet scientists call the cosmological principle, our place in space is in no way exceptional. But recent observations could overturn this long-held assumption By Sarah Scoles edited by Lee Billings & Jeanna Bryner An illustration of the cosmic web, the universe’s large-scale structure of composed of
