Wildfires destroy and alter carbon in forests. The remaining carbon can be difficult for many organisms to consume. New research shows that one type of fungi thrives after wildfires because it has genes that allow it to feed on carbon altered by fires. The research helps to explain how carbon returns to the food web after a fire.
People who think they know a lot about COVID-19 vaccines are more likely to hold vaccine misperceptions, according to a new survey from a nationwide coalition of university-based researchers.

Women who deliver babies at Catholic hospitals are about half as likely to have undergone a sterilization procedure to prevent unwanted pregnancies after the birth as those who delivered elsewhere, a new study has found. The new research, which includes data from 17,098 births and appears in the journal Perspectives on Sexual and Reproductive Health, is the first of its kind to examine differences in use of highly effective birth control methods based on Catholic hospital delivery.

Mandalas are geometric configurations of shapes that have their origins in Buddhist traditions. The colouring of mandala shapes is increasingly popular as a way for people to attempt ‘mindfulness’, a way of being present in the moment, and which has been associated with helping people to improve their mental health and wellbeing.
Neutrinos are arguably the most fascinating elementary particle in our universe. In cosmology they play an important role in the formation of large-scale structures, while in particle physics their tiny but non-zero mass sets them apart, pointing to new physics phenomena beyond our current theories.

A new study at Children’s Hospital Los Angeles independently verified the value of a system that assesses hepatoblastoma risk in children. Hepatoblastoma is a rare childhood liver cancer, usually seen within the first three years of a child’s life with 50 to 70 cases occurring in the U.S. each year.
A new Baycrest study reports that older adults store too much information in their brains, leading them to have “cluttered” memories. As a result of these cluttered memories, they have more trouble remembering specific and detailed information compared to younger adults.

Researchers changed the atomic structure of a thermoelectric material in a unique way with pulses of intense laser light. This new approach has the potential to create unique materials with dramatic properties that are not seen in nature.
In 1873, Russian doctor J. von Rusitzky coined the term “multiple myeloma” after finding eight different types of bone marrow tumors in a single patient. Nearly 150 years later, using advanced cell sequencing technology and state-of-the-art imaging techniques, researchers at Roswell Park Comprehensive Cancer Center have provided a molecular and biological explanation for this finding, discovering that different myeloma clones can be present in a single patient and linking these distinct genetic changes in myeloma cells to the development of myeloma bone disease.
One population of female common yellowthroats prefers males with larger black masks, but another group of females favors a larger yellow bib. A new study has found that both kinds of ornaments are linked to superior genes.
A new analysis, published this week in the Proceedings of the National Academy of Sciences, shows that the carbon emissions from using land to grow corn can negate or even reverse any climate advantages of corn ethanol relative to gasoline.
The source of Earth’s water has been a longstanding debate and Lawrence Livermore National Laboratory (LLNL) scientists think they have the answer—and they found it by looking at rocks from the moon.
An international team of researchers found that the distribution of mutations is skewed toward areas of the genome that are less likely to cause harm and more likely to benefit the organism.
About half of the world’s population is self-employed, and self-employed women earn only about half as much as men, according to the World Bank. Social scientists believed for years that increasing women’s access to capital would shrink the earnings gap.
Higher levels of racial inequality in political disenfranchisement are linked to negative health outcomes in Black populations in the United States, according to a new Florida State University study.Assistant Professor of Sociology and Associate Director of the Public Health Program Patricia Homan, the study’s lead author, said it revealed that racialized disenfranchisement is accompanied by health problems including depression, physical limitations and disability.

Irvine, Calif., Feb. 14, 2022 — In a new Nature Astronomy study, an international team led by astrophysicists from the University of California, Irvine and Pomona College report how, when tiny galaxies collide with bigger ones, the bigger galaxies can strip the smaller galaxies of their dark matter — matter that we can’t see directly, but which astrophysicists think must exist because, without its gravitational effects, they couldn’t explain things like the motions of a galaxy’s stars.
Even the best laser has “quantum noise” that makes images from microscopy blurry and hides details. This results in measurements that are less precise than scientists need. Researchers have designed a new type of microscope that uses quantum squeezed light to reduce measurement uncertainty, enabling a 50 percent improvement in the sensitivity of a specific scientific measurement.
Most patients who show signs of alcohol or opioid/stimulant drug use associated with injury now undergo screening and/or intervention in Level I and II trauma centers, according to national survey results.
A study led by researchers at Johns Hopkins Carey Business School found a surprising misalignment between the tax subsidies received by nonprofit hospitals in the United States and the community benefit that these hospitals provide.

Researchers at the Yale Cancer Biology Institute have clarified the role of a recurring cancer-associated tumor mutation in glioblastoma multiforme (GBM), the most common and most aggressive type of malignant brain tumor. The findings were published in Nature.
A new study explores how specialized care providers navigate conversations with patients and their families about switching from curative treatments to pain management and comfort care. Many of the providers did not dismiss their patients’ emotions or tell patients to feel differently. Rather, they validated their patients’ fear, hope or guilt, and then walked them through the likely outcomes of continuing treatments.
Speech recognition technology allows us to ask Siri to check the weather for tomorrow, or to ask Alexa to play our favorite song. But those technologies require audible speech. What if a person can’t speak, or if vocalized speech in a particular setting isn’t appropriate?
Reports of taste loss are genuine in people with COVID-19 and indistinguishable from smell loss. The new study examines the prevalence of taste loss in COVID-19 patients and how the way the symptom was measured might impact the prevalence estimate.
Exposure to alcohol in the womb exacerbates children’s vulnerability to social and environmental stressors and to mental health issues in adulthood, according to a new study. Prenatal alcohol exposure (PAE) is known to cause neurocognitive and physical conditions, including facial and growth abnormalities. Previous research has also linked PAE to long-term mental health effects, though these outcomes are not well understood. This is partly because the impact of alcohol exposure before birth is difficult to separate from the effects of other early social and environmental stressors, including adverse childhood experiences, that often accompany PAE. For the new study in Alcoholism: Clinical & Experimental Research, investigators compared mental health conditions among adults who’d been exposed to alcohol before birth with those who weren’t. They also explored the role of early childhood adversity and other social and environmental factors on mental health.
Treatment for COVID-19 should be based on clinical judgment and not just testing, according to a Rutgers study that found testing alone is missing some people with the virus, especially those at high risk who need therapeutic treatments.
A study by researchers at Mayo Clinic Cancer Center in Florida is validating the use of genomic sequencing to predict the likelihood that patients with gastric cancer will derive benefit from chemotherapy or from immunotherapy. The study is published in Nature Communications.
