Abdale on October 27, 2026 • ( 0 ) Ctenacanthus, meaning “comb spine”, was a prehistoric proto-shark which lived from the late Devonian Period to the early Permian Period 370-270 million years ago. Skeleton of Dracopristis hoffmanorum, a relative of Ctenacanthus…
A synchronized vertical-and-oblique drone system reconstructed curved dugong bodies in three dimensions, reducing measurement error in challenging frames and providing an objective way to assess posture.
The whole point of reproduction is that you produce more of your own species, right? Well, not exactly, and not if you are an Iberian harvester ant (Messor ibericus). Amazingly, this ant can propagate individuals of two different species by…
Home › Paleontology › Sphenacanthus By Jason R. Abdale on October 21, 2026 • ( 0 ) Sphenacanthus, meaning “wedge spine”, was a genus of primitive proto-shark measuring 3 feet long which lived from the late Devonian Period to the end of the Permian Period 360-252 million years ago. Far…
In biology, there are questions to be asked and problems to be solved. Through the biology program at the University of New Haven, you will learn to do both successfully, applying the theoretical knowledge you gain in the classroom in…
A sediment trap moored at 500 metres in the Ross Sea captured over 210,000 mesopelagic organisms across three decades, producing the first year-round checklist of Antarctic swimmers. Article Title: First year-round occurrence checklist of mesopelagic “swimmers” collected by an automatic sediment trap…
“Fall like a maple seed, sail like a boat” sounds like advice from legendary heavyweight boxer Muhammad Ali. In reality, it describes a new robotic platform scientists have created for fast, long-term deployment to monitor remote waters. Monitoring remote locations…
Researchers at the Singapore University of Technology and Design (SUTD) have built a small robot that drops from the sky, spins like a maple seed on the way down, and lands softly on the water. Then it turns its wings…
Lea Eggensberger said that to understand the type of sediment lying at the bottom of a body of water, sometimes you have to poke it. That’s a very simple way of describing how the modular penetrometer, or ModPen, works. The…
Our story begins on a North Carolina farm, with long rows of tomato plants stretching out across the fields. Laid over the soil of each row is a thin layer of plastic, added to retain moisture and suppress weed growth.
