Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought
The existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk. New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought. (2018-03-22)

CT scans reveal new muscles in horseshoe crab appendages
Digital dissection shows that two horseshoe crab appendages -- the pushing leg and the male pedipalp -- each have one more muscle than had been thought, according to a study published Feb. 14, 2018 in the open-access journal PLOS ONE by Russell Bicknell from University of New England, Australia, and colleagues. (2018-02-14)

Sandy claws
Majoid crabs -- known as decorator crabs -- adorn themselves with items secured from their surroundings such as sponges, algae and other marine debris. Scientists and students at the University of Delaware are exploring what factors drive this behavior. (2017-12-08)

Crabs in your computer
A study published in GigaScience provides three-dimensional visual data from hermit crabs using 3-D microCT scanning technology. The authors not only describe the data, they also provide downloadable, interactive files of everything in this study, allowing everyone to use and manipulate the data. They even include interactive web-based viewers and 3-D printable file formats. Making this complex data publicly available, allows researchers cost-efficient options for examining specimens without the need to send out precious samples. (2018-03-14)

Feces from entangled North Atlantic right whales reveals 'sky-high' stress levels
In a new study published this week in Endangered Species Research, North Atlantic right whale scientists found that whales who undergo prolonged entanglements in fishing gear endure 'sky-high hormone levels,' indicating severe stress, which researchers discovered using a pioneering technique of examining scat from live, entangled, and dead whales over 15 years. (2017-11-29)

Hubble celebrates its 29th birthday with unrivaled view of the Southern Crab Nebula
This incredible image of the hourglass-shaped Southern Crab Nebula was taken to mark the NASA/ESA Hubble Space Telescope's 29th anniversary in space. The nebula, created by a binary star system, is one of the many objects that Hubble has demystified throughout its productive life. This new image adds to our understanding of the nebula and demonstrates the telescope's continued capabilities. (2019-04-18)

NUS geography researchers determine benefits of Singapore's mangroves
A three-year study conducted by researchers from the National University of Singapore has identified that apart from cultural benefits, mangroves act as nursery habitat for fish and as coastal defence, as well as storing carbon that could help offset some of our climate change emissions. (2018-04-26)

Unprecedented number of warm-water species moved northward during marine heatwave
A UC Davis study documents an unprecedented number of southern marine species moving northward into California and as far north as Oregon during the 2014-2016 marine heatwave. Of 67 rare, warm-water species sightings observed, 37 had never been documented so far north before. (2019-03-12)

Five new blanket-hermit crab species described 130 years later from the Pacific
Unlike most hermit crabs, the blanket-hermit crab does not use empty shells for protection, and instead lives symbiotically with a sea anemone. The crab uses the anemone to cover its soft abdomen, and can pull the anemone's tissue over its head to protect itself whenever necessary. Since 1888, this crab had been considered a unique species until a research team recently described five new ones and a new genus in the open access journal ZooKeys. (2018-04-23)

When enemies come to help
The enemy of my enemy is my friend. Now researchers at the University of Zurich show that this principle also holds for crab spiders and flowering plants. While it's true that the spiders do eat or drive away useful pollinators such as bees, they're also attracted by floral scent signals to come and help if the plant is attacked by insects intent on eating it. (2018-04-10)

Trophy hunting may cause extinction in a changing environment
Trophy hunting and other activities involving the targeting of high-quality male animals could lead to the extinction of certain species faced with changing environmental conditions, according to new research from Queen Mary University of London. (2017-11-28)

Ancient meteorite impact sparked long-lived volcanic eruptions on Earth
Large impacts were common on the early Earth and were likely much more important than previously thought in shaping our planet. The findings raise interest in the possibility of volcanism also shaping similar structures on Mercury, Venus, Mars and the Moon. (2017-05-03)

Estuaries protect Dungeness crabs from deadly parasites
Parasitic worms can pose a serious threat to the Dungeness crab, a commercially important fishery species found along the west coast of North America. The worms are thought to have caused or contributed to the crash of the crab fishery of central California during the last half century. New research shows that infected crabs can rid themselves of parasites by moving into the less salty water of estuaries. Low salinity kills the worms creating a parasite refuge for the crabs. (2015-05-22)

Caught red-handed: The 'candy-striped hermit crab' is a new species from the Caribbean
A new secretive species of hermit crab living in crevices shared with moray eels and flaming reef lobsters, has been discovered in the southern Caribbean. The striped color pattern reminded the author of candy canes, hence the common name 'candy-striped hermit crab.' Observations of live specimens suggest that the new hermit crab engages in 'cleaner' activities, or is a 'den commensal' with moray eels. The study is published in the open-access journal ZooKeys. (2017-01-26)

Biomimetic micro/nanoscale fiber reinforced composites
For the first time, through a programmed and consecutive 'brushing-and-laminating' assembly strategy, macroscopic 3-D bulk biomimetic twisted plywood structural materials with comprehensive mimicry of structural and mechanical characteristics of their natural counterparts are successfully fabricated from 1D micro/nanoscale building blocks under mild conditions. As expected, they achieve excellent mechanical properties superior to many natural, artificial and engineering materials. More importantly, the proposed assembly strategy is high-efficient, scalable and material-independent. (2018-08-10)

The highest energy gamma rays discovered by the Tibet ASgamma experiment
The Tibet ASgamma experiment, a China-Japan joint research project, has discovered the highest energy cosmic gamma rays ever observed from an astrophysical source - in this case, the 'Crab Nebula.'
