Kaboom! Ancient impacts scarred moon to its core, may have created ’man in the moon’

Ohio State University planetary scientists have found the remains of ancient lunar impacts that may have helped create the surface feature commonly called the “man in the moon.”

Their study suggests that a large object hit the far side of the moon and sent a shock wave through the moon’s core and all the way to the Earth-facing side. The crust recoiled — and the moon bears the scars from that encounter even today.

The finding holds implications for lunar prospectin

UF scientists trace origin of shark’s electric sense

Sharks, people have electric connection in their lineage

Sharks are known for their almost uncanny ability to detect electrical signals while hunting and navigating.

Now researchers have traced the origin of those electrosensory powers to the same type of embryonic cells that gives rise to many head and facial features in humans.

The discovery, reported by University of Florida scientists in the current edition of Evolution & Development, identifies neural

Not just the birds

Introduced foxes throw a wrench in the food web

Indirect effects of predators

In an extensive study, researchers from the University of Montana, University of California – Santa Cruz, and the University of California – Davis have shown that a top predator strongly affected plants and animals at the bottom of an island food web by eating organisms that transport nutrients between ecosystems. “An introduced predator alters Aleutian island plant communities by thw

New Sonar Method Offers Way to Assess Health of Squid Fisheries

Scientists devise technique to detect squid egg clusters on the seafloor

California’s $30-million-a-year squid fishery has quadrupled in the past decade, but until now there has been no way to assess the continuing viability of squid stocks. A multi-institutional team of scientists this month reported a new sonar technique to locate squid egg clusters in the murky depths, offering a window onto next year’s potential squid population in its nursery.

The scientists demonstra

Antarctic krill provide carbon sink in Southern Ocean

New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth’s surface than was previously understood. The results are published this week in the journal Current Biology.

Scientists from British Antarctic Survey (BAS) and Scarborough Centre of Coastal Studies at the University of Hull discovered that rather than doing so once per 24 hours, Ant

One fish, two fish: New MIT sensor improves fish counts

Work could help definitively determine whether fish populations are shrinking

Researchers at MIT have found a new way of looking beneath the ocean surface that could help definitively determine whether fish populations are shrinking.

A remote sensor system developed by Associate Professor Nicholas Makris of mechanical engineering, along with others at MIT, Northeastern University and the Naval Research Laboratory, allows scientists to track enormous fish populatio
