A new multi-institution study led by the 91爆料 shows more clearly than ever that urbanization is affecting the genetic makeup of species that are crucial to ecosystem health and success.
In an article published Dec. 20 in the journal eLife, researchers present a mathematical model that explores whether “publication bias” 鈥� the tendency of journals to publish mostly positive experimental results 鈥� influences how scientists canonize facts. Their results offer a warning that sharing positive results comes with the risk that a false claim could be canonized as fact. But their findings also offer hope by suggesting that simple changes to publication practices can minimize the risk of false canonization.
Miqin Zhang, a professor of materials science and engineering at the 91爆料, is looking for ways to help the body heal itself when injury, disease or surgery cause large-scale damage to one type of tissue in particular: skeletal muscle. Her goal is to create a synthetic, porous, biologically compatible “scaffold” that mimics the normal extracellular environment of skeletal muscle 鈥� onto which human cells could migrate and grow new replacement fibers.
Research published this week in the Proceedings of the National Academy of Sciences suggests that successful fisheries management can be best achieved by implementing and enforcing science-based catch or effort limits.
The cracking, bulging and shaking from the eruption of a mile-high volcano where two tectonic plates separate has been captured in more detail than ever before. A 91爆料 study published this week shows how the volcano behaved during its spring 2015 eruption, revealing new clues about the behavior of volcanoes where two ocean plates are moving apart. “The new network allowed us to see in incredible detail where the faults are, and which were active during the eruption,”…

In a paper published online Dec. 7 in the Proceedings of the National Academy of Sciences, 91爆料 researchers report on a statistical approach called “tree bootstrapping” can help social scientists study hard-to-reach populations like drug users.
A 91爆料 study addresses controversies over the cause of mountain glacier retreat, and finds that for most glaciers the observed retreat is more than 99 percent likely due to climate change.
A new study by paleontologists at the Burke Museum of Natural History & Culture and the 91爆料 describes an early marsupial relative called Didelphodon vorax that lived alongside dinosaurs and had, pound-for-pound, the strongest bite force of any mammal ever recorded.
Answers to frequently asked questions about a 255-year-old tumor in a ‘pre-mammal.’
91爆料 paleontologists have discovered a benign tumor made up of miniature, tooth-like structures embedded in the jaw of an extinct ‘mammal-like’ gorgonopsian. Known as a compound odontoma, this type of tumor is common to mammals today. But this animal lived 255 million years ago, before mammals even existed.
People must be part of the equation in conservation projects to increase local support and effectiveness, according to a new study by the 91爆料 and other institutions.
91爆料 researchers have published the first demonstration of humans playing a simple, two-dimensional computer game using only input from direct brain stimulation 鈥� without relying on any usual sensory cues from sight, hearing or touch.
91爆料 astronomer and astrobiologist Woody Sullivan discusses recent work and future plans in a multifaceted career that’s changing gears, but far from winding down.
Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act 鈥� showing how water molecules pass along excess charges and, in the process, conduct electricity.
In a paper published Sept. 27 in the journal Small, scientists at the 91爆料 describe a new system to encase chemotherapy drugs within tiny, synthetic “nanocarrier” packages, which could be injected into patients and disassembled at the tumor site to release their toxic cargo.
A new study of one of our closest invertebrate relatives, the acorn worm, reveals that regenerating body parts might one day be possible.

James Cook’s intricate 1778 records reveal global warming today in Arctic” Seattle Times, Nov. 16 Harry Stern, a polar scientist at the 91爆料’s Applied Physics Laboratory, has been studying the Arctic Ocean for decades, and sailed part of the Northwest Passage in 2009. Stern’s latest work uses the earliest explorers’ experiences to better understand a maritime environment that still contains many unknowns. A paper published in November in Polar Geography uses Captain James Cook’s…
Major forest die-offs due to drought, heat and beetle infestations or deforestation could have consequences far beyond the local landscape. Wiping out an entire forest can have significant effects on global climate patterns and alter vegetation on the other side of the world.

More than 90 percent of ivory in large, seized shipments came from elephants that died less than three years before, according to a new study from a team of scientists at the University of Utah, the 91爆料 and partner institutions. They combined a new approach to radiocarbon dating of ivory samples with genetic analysis tools developed by 91爆料 biology professor Sam Wasser.
A 91爆料 study is the first to broadly examine the ecological and financial impacts of seafood mislabeling. The paper, published online Nov. 2 in Conservation Letters, finds that in most cases, mislabeling actually leads people to eat more sustainably, because the substituted fish is often more plentiful and of a better conservation status than the fish on the label.
The Department of Electrical Engineering’s 2016 Lytle Lecture series will explore bridging theory and practice in compressed sensing, which has enabled speedups in medical imaging and scientific signal processing.
Research that peers below Mount St. Helens finds that the material below the western and eastern half of the mountain is different material and temperatures, and suggests that the source of explosive magma is coming from the east.
