By all appearances, the universe beyond Earth is a vast, lonely, and sterile space. Yet, wherever humans may travel, an abundance of microbial life will follow.
Walking with coffee is something most of us do every day without considering the balancing act it requires. In fact, there's a lot of physics preventing the coffee from spilling over.
Some coral communities are becoming more heat tolerant as ocean temperatures rise, offering hope for corals in a changing climate.
Understanding how pathogens evolve is a fundamental component of learning how to protect ourselves and our world from pests and diseases. Yet we are constantly underestimating pathogen evolution, such as in the case of the COVID-19 pandemic, which some believed had been conquered until the arrival of the Delta variant. Similarly, we are often a step or two behind plant pathogens, which is why the...
Research recently published by adjunct assistant professor Cyler Conrad from the Department of Archaeology at The University of New Mexico examines the importance of turkeys to the Ancestral Pueblo people and how they have managed the birds for more than 1,600 years. Evidence of turkeys and various methods of enclosing them is evident in the ancient pueblos all over New Mexico and surrounding...
The Journal of Alloys and Compounds has published an article coauthored by the Institute of Solid State Chemistry and Mechanochemistry (the Ural Branch of the Russian Academy of Sciences), the Donostia International Physics Centre, and the HSE Tikhonov Moscow Institute of Electronics and Mathematics on the characteristics of cubic double perovskite oxides. To date, experimental measurements of the...
A New Zealand-led international study published today in Global Change Biology reveals how climate change may impact seals in one of the most remote ocean regions in the world, the Weddell Sea.
Atlantic hurricanes don't just come and go. They leave clues to their passage through the landscape that last centuries or more. Rice University scientists are using these natural archives to find signs of storms hundreds of years before satellites allowed us to watch them in real time.
Without the prospect of herd immunity on the immediate horizon, speedy detection for COVID-19 remains imperative for helping to curb the pandemic. Point-of-care testing that can provide immediate results is an urgent need.
By testing easier-to-study coyotes, researchers from the Cornell Wildlife Health Lab at the College of Veterinary Medicine, in collaboration with the Cheyenne River Sioux tribe, have identified a range of lethal diseases threatening black-footed ferrets—one of the most endangered animals in North America.
By the end of the century, scientists expect climate change to reduce corn yield significantly, with some estimating losses up to 28%. But those calculations are missing a key factor that could drag corn yields down even further: Weeds.
A powerful experimental laser developed by the European Southern Observatory (ESO), TOPTICA Projects and other industry partners passed a key test last month at the Allgaeuer Volkssternwarte Ottobeuren observatory in Germany. The adaptive-optics laser has important additional capabilities compared to existing systems. It is to be installed at the European Space Agency's (ESA) Optical Ground...
A study in which machine-learning models were trained to assess over 1 million companies has shown that artificial intelligence (AI) can accurately determine whether a startup firm will fail or become successful. The outcome is a tool, Venhound, that has the potential to help investors identify the next unicorn.
A breakthrough in stabilizing nanocrystals introduces a low-cost, energy-efficient light source for consumer electronic devices, detectors and medical imaging.
With up to 2.4 million U.S. cases and over 250 million chronic cases globally, hepatitis B infection persists despite the availability of a vaccine. Vaccines work by immunizing the body against a virus to prevent infection; however, there is no cure for individuals who do become infected (for example, at birth). Hepatitis B infection can lead to liver damage and even cancer, posing a threat to...
Researchers at Columbia University Mailman School of Public Health and the University of Ibadan, Nigeria, led a randomized control trial in Ibadan, Nigeria, to evaluate educational programs to empower women by working with couples in three critical areas: Spousal relations, and financial and reproductive decision-making.
A series of recent research papers from a McGill-led team has found that the herbicide glyphosate—commonly sold under the label Roundup—can alter the structure of natural freshwater bacterial and zooplankton communities. Notably, the researchers found that for zooplankton, aquatic concentrations of 0.1 mg/L glyphosate were sufficient to cause diversity loss.
Electrochemical reactions that are accelerated using catalysts lie at the heart of many processes for making and using fuels, chemicals, and materials—including storing electricity from renewable energy sources in chemical bonds, an important capability for decarbonizing transportation fuels. Now, research at MIT could open the door to ways of making certain catalysts more active, and thus...
In their search for pink river dolphins, researchers in the Peruvian Amazon scooped up river water sloshing with genetic material that they hoped could trace the elusive creatures.
CTCF is a transcription factor that has been a research target due to its role in regulating a critical oncogene called MYC. Scientists at St. Jude Children's Research Hospital have found direct evidence that CTCF governs chromatin accessibility, the process of opening tightly spooled DNA so that genes can be expressed. The findings were published in Genome Biology.
New research from Washington University in St. Louis suggests that bacteria could learn from the past to predict the future.
Soon, $50 and $100 bills may be a thing of the past. That's the future some economists are predicting—and want.
Another summer fish kill hit Biscayne Bay over the holiday weekend as oxygen-starved waters appeared to smother dozens of fish, the latest indicator of a pollution problem Miami-Dade County needs to fix.
"The dream of predicting a protein shape just from its gene sequence is now a reality," said Paul Adams, Associate Laboratory Director for Biosciences at Berkeley Lab. For Adams and other structural biologists who study proteins, predicting their shape offers a key to understanding their function and accelerating treatments for diseases like cancer and COVID-19.
