Whether birds get caged in the eye of a hurricane may depend on the intensity and totality of the chaos beyond the calm, says a novel study from the University of Nebraska–Lincoln's Matthew Van Den Broeke.
Oil and gas emissions vary widely throughout the supply chain, making mitigation of both super-emitters and emissions sources near populations top priorities for public health and climate, according to findings from a literature review by the nonprofit energy science and policy institute Physicians, Scientists, and Engineers (PSE) for Healthy Energy. "Methane and Health-Damaging Air Pollutants...
Nature is full of repeating patterns that are part of the beauty of our world. An international team, including a researcher from the University of Washington, used modern tools to explain repeating patterns of stones that form in cold landscapes.
Two NAU astronomers presented groundbreaking research at the annual meeting of the Division for Planetary Sciences, a branch of the American Academy of Sciences.
Researchers report that pairing a newly developed fibrin gel with CAR-T immunotherapy that was delivered to post-surgical mouse brains with glioblastoma improved the immunotherapy's effectiveness. The gel aided CAR-T cell distribution in the brain by acclimating the T cells to the post-surgical wound environment while also stopping the tumor from recurring.
Massages feel good, but do they actually speed muscle recovery? Turns out, they do. Scientists applied precise, repeated forces to injured mouse leg muscles and found that they recovered stronger and faster than untreated muscles, likely because the compression squeezed inflammation-causing cells out of the muscle tissue. This work offers a non-invasive, drug-free treatment that can help...
Scientists provide promising new evidence that the 'planar cell polarity,' a powerful signaling pathway, is a widely used mechanism for the formation and maintenance of a large number of synapses.
The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent articles use data from meteorites derived from Vesta to resolve the 'missing mantle problem' and push back our knowledge of the solar system to just a couple of million years after it began to form.
For millions of people living in rural communities in sub-Saharan Africa, accessing timely care during maternal and neonatal emergencies remains a complex problem.
A sweeping analysis of marine fossils from most of the past half-billion years shows the usual rules of body size evolution change during mass extinctions and their recoveries. The discovery is an early step toward predicting how evolution will play out on the other side of the current extinction crisis.
Whether birds get caged in the eye of a hurricane may depend on the intensity and totality of the chaos beyond the calm, says a novel study.
Paleoanthropologists have wondered how and why humans evolved molars that emerge into the mouth at specific ages and why those ages are so delayed compared to living apes. It is the coordination between facial growth and the mechanics of the chewing muscles that determines not just where but when adult molars emerge. This results in molars coming in only when enough of a 'mechanically safe' space...
The Tomb of Nestor's Cup, a famous burial in Italy, contains not one deceased individual, but several, according to a study published October 6, 2021 in the open-access journal PLOS ONE by Melania Gigante of the University of Padua, Italy and colleagues.
Six, 12, and 18. These are the ages that most people get their three adult molars or large chewing teeth towards the back of the mouth. These teeth come in at a much later age than they do in our closest living relative, the chimpanzee, who get those same adult molars at around three, six, and 12 years old. Paleoanthropologists have wondered for a long time how and why humans evolved molars that...
Humans in the Middle East were using complex fishing tools and techniques by 12,000 years ago, according to a study published October 6, 2021 in the open-access journal PLOS ONE by Antonella Pedergnana of the Archaeological Research Centre and Museum for Human Behavioural Evolution in Mainz, Germany and colleagues.
Scientists hope that tiny sacs of material excreted by cells -- so-called extracellular vesicles -- can be used to deliver drugs inside the body. Researchers now show that these nano-bubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique shows promising results in animal models.
An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research. The research team developed a computer modeling approach that revealed the effect of the Montreal Protocol and subsequent amendments on stratospheric ozone, the...
A new study showed a link between an individual's sense of purpose and their ability to recall vivid details. The researchers found that while both a sense of purpose and cognitive function made memories easier to recall, only a sense of purpose bestowed the benefits of vividness and coherence.
Experiments and modeling work offers new insights into the striking patterns of repeating stones seen in frost-prone landscapes.
What are some skywatching highlights in October 2021? See several groupings of the Moon, planets, and stars at sunrise and sunset. Then get to know two bright stars that are part of a special group: along with a handful of others, they take turns with Polaris as North Star over thousands of years.

Care for the 15 most prevalent types of cancer in the U.S. cost approximately $156.2 billion in 2018, according to a team researchers. The team also found that medication was the biggest expense and that medication expense for breast, lung, lymphoma and colorectal cancers incurred the most costs.
In 2013, the U.S. government began investing $100 million to decipher human brain anatomy in a large collaborative project called the BRAIN Initiative. Researchers built tools and set standards for describing all the cells in the brain. On October 7, 2021 the initiative reached a major milestone, publishing a comprehensive census of cell types in the mouse, monkey, and human primary motor cortex.
When comparing two of the most common weight loss surgeries, a research team found that long-term, sleeve gastrectomy is safer than gastric bypass for Medicare patients.
