Microscopic fish teeth may carry a message of hope from an ecological upheaval in the distant past, scientists at Yale University and the University of California-San Diego (UCSD) have found.
An analysis of tooth fossils and shark scales from the sea floor indicates that a massive die-off of species 66 million years ago did not, in fact, leave uniformly dead oceans around the world. In the Pacific Ocean, at least, some small fish species actually flourished. (more…)
The universe’s oldest, brightest beacons may have gorged themselves in the dense, cold, gas flows of the early cosmos — creating a kind of energy drink for infant black holes in the young universe — according to new research by scientists at Yale University and the Weizmann Institute in Israel.

Anyone who’s read a children’s menu at a restaurant knows that kids and adults tend to like different foods. New research suggests at least one animal species had the same arrangement half a billion years ago.
It seems the earliest ancestors of spiders and horseshoe crabs, called chelicerates, had separate ecological niches for adults and larvae. They ate different foods, in other words, and did not compete for the same prey. This approach has been seen in many modern animal species, but never in one this old. (more…)
From the physics labs at Yale University to the bottom of a played-out gold mine in South Dakota, a new generation of dark matter experiments is ready to commence.
The U.S. Department of Energy’s Office of Science and the National Science Foundation recently gave the go-ahead to LUX-Zeplin (LZ), a key experiment in the hunt for dark matter, the invisible substance that may make up much of the universe. Daniel McKinsey, a professor of physics, leads a contingent of Yale scientists working on the project. (more…)
A man with almost no hair on his body has grown a full head of it after a novel treatment by doctors at Yale University.
There is currently no cure or long-term treatment for alopecia universalis, the disease that left the 25-year-old patient bare of hair. This is the first reported case of a successful targeted treatment for the rare, highly visible disease. (more…)
Precise answers to these questions have long eluded scientists. But new research led by Daniel Field of Yale University and the Smithsonian Institution recasts the turtle’s disputed evolutionary history, providing fresh evidence that the familiar reptiles are more closely related to birds and crocodiles than to lizards and snakes.

Understanding the roots of a global, contagious spread of online information may help better predict political revolutions, consumer behavior, box office revenues, public policy debates, and even public health epidemics, a new study co-led by Yale University reveals. The model devised for this study, which identifies those roots and analyzes common patterns of dissemination on a global scale, even predicted the rise of “#Obamacare” as a global Twitter trend. The study appears in PLOS ONE.
Attempts to globally monitor the spread of online information have become increasingly difficult because of the explosive growth in the amount of information available and heightened concerns about personal privacy. To get a better understanding of social contagion, the team focused instead on smaller, local network structures, where messages are transmitted from individuals at the center and spread out rapidly to other individuals, who then retransmit them.

Deforestation may have far greater consequences for climate change in some soils than in others, according to new research led by Yale University scientists — a finding that could provide critical insights into which ecosystems must be managed with extra care because they are vulnerable to biodiversity loss and which ecosystems are more resilient to widespread tree removal.
In a comprehensive analysis of soil collected from 11 distinct U.S. regions, from Hawaii to northern Alaska, researchers found that the extent to which deforestation disturbs underground microbial communities that regulate the loss of carbon into the atmosphere depends almost exclusively on the texture of the soil. The results were published in the journal Global Change Biology. (more…)
