Resilience in the depths: Silky shark regenerates wounded dorsal fin
A skin resembling armor, rapid healing abilities, continuous tooth renewal and the capability for limb regeneration—this might sound like the description of a creature from a superhero film. Surprisingly, these are standard features of a well-known.....»»
NASA telescopes chase down "Green Monster" in star"s debris
By bringing together data from two NASA telescopes, astronomers may have solved a mystery around a bizarre structure found in the debris field of an exploded star. Their work has uncovered new details about the star's remains, and about the explosion.....»»
Researchers engineer skin bacteria that are able to secrete and produce molecules that treat acne
International research led by the Translational Synthetic Biology Laboratory of the Department of Medicine and Life Sciences (MELIS) at Pompeu Fabra University has succeeded in efficiently engineering Cutibacterium acnes, a type of skin bacterium, to.....»»
Unraveling the mystery of lignosuberization: A comprehensive study of periderm formation in Sikkim cucumber fruit skin
In fleshy fruits, periderm tissue often forms on the skin surface as a response to mechanical damage caused following environmental cues or developmental programs, known as lignosuberization, creating a protective, corky matrix......»»
Families will change dramatically over the years to come, says study
The number of relatives that an individual has is expected to decrease by more than 35% in the near future. At the same time, the structure of families will change. The number of cousins, nieces, nephews and grandchildren will decline sharply, while.....»»
How a sea animal with a "snot palace" could inspire better pumps
To build more efficient pumping systems, engineers might take inspiration from a tiny filter-feeding sea creature encased in a gelatinous structure known as a "mucus house" or "snot palace.".....»»
Coal miners in North Dakota unearth a mammoth tusk buried for thousands of years
The first person to spot it was a shovel operator working the overnight shift, eyeing a glint of white as he scooped up a giant mound of dirt and dropped it into a dump truck......»»

Titan"s "magic islands" are likely to be honeycombed hydrocarbon icebergs, finds study
Titan's "magic islands" are likely floating chunks of porous, frozen organic solids, a new study finds, pivoting from previous work suggesting they were gas bubbles. The study was published in Geophysical Research Letters......»»
Engineers invent octopus-inspired technology that can deceive and signal
With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers at the University of California, Irvine have d.....»»
New evidence that insect wings may have evolved from gills
How did insect wings originate? This is a question that represents an unsolved mystery of insect evolution. Despite many years of research, it is still not entirely clear from which body structure insect wings actually evolved and what their original.....»»
DriveFS Sleuth: Open-source tool for investigating Google Drive File Stream’s disk forensic artifacts
DriveFS Sleuth automates the investigation of Google Drive File Stream disk artifacts. The tool can parse the disk artifacts and build a filesystem tree-like structure enumerating the synchronized files along with their respective properties. “.....»»
