Fungi could manipulate bacteria to enrich soil with nutrients
Symbiotic relationships between plants and soil microbes could yield new methods for enriching soil and improving crop yields. Researchers have discovered that fungi living symbiotically with most land plants have a bacterial "microbiome" that may help the fungi access soil nutrients and share them with their host plants. Identifying the specific beneficial bacteria and how the fungi attract them...
Health and academic professionals with dependents at high risk of quitting after COVID-19
Up to one in five employees at an academic medical institution are considering leaving their professions due to the strains of coping with the pandemic in their own lives, according to a new University of Utah Health study. The findings suggest that retaining highly trained doctors, nurses, and scientists in the aftermath of the COVID-19 pandemic could be the next great health care challenge.
Hidden diversity of coral more important for conservation than previously thought
Researchers say that our framework for classifying coral species needs to be expanded to capture ecological diversity and protect reef environments after discovering surprising differences between cryptic coral species.
How pathogenic bacteria weather the slings and arrows of infection
Infectious diseases are a leading cause of global mortality. During an infection, bacteria experience many different stresses. In this arms race to outwit their competition, bacteria have evolved mechanisms to stay alive in the face of adversities. One such mechanism is the stringent response pathway. Understanding how the activation of the stringent response pathway is controlled can provide...
In-situ nanoscale insights into the evolution of solid electrolyte interphase shells
Straightforward visualized evidence of SEI shells evolution during Li deposition/stripping to reveal anode degradation is provided via in-situ atomic force microscopy (AFM). Nucleation and growth of quasi-spherical Li particles are observed on a Cu substrate, followed by Li stripping and collapse of SEI shells. In subsequent cycling, new Li deposits tend to nucleate at pristine sites with fresh...
Keep pace: Walking with a partner is great but might slow you down
A new study by Purdue University researchers shows that couples often decreased their speed when walking together. Speed further decreased if they were holding hands.
Kirigami-style fabrication may enable new 3D nanostructures
A new technique that mimics the ancient Japanese art of kirigami may offer an easier way to fabricate complex 3D nanostructures for use in electronics, manufacturing and health care.
Lanternfly's attraction to vertical silhouettes could help monitor, trap it
Like moths to a flame, spotted lanternflies are visually drawn toward and seemingly captivated by vertical objects such as utility poles, a behavior that could be valuable in predicting where the pests might be heading, according to entomologists in Penn State's College of Agricultural Sciences.
Mapping policy for how the EU can reduce its impact on tropical deforestation
EU imports of products contribute significantly to deforestation in other parts of the world. In a new study, published in One Earth, researchers from University of Louvain and Chalmers University of Technology, evaluated thousands of policy proposals for how the EU could reduce this impact, to assess which would have the largest potential to reduce deforestation.
Massive X-ray screening identifies promising candidates for COVID drugs
A team of researchers has identified several candidates for drugs against the coronavirus SARS-CoV-2 at DESY´s high-brilliance X-ray lightsource PETRA III. They bind to an important protein of the virus and could thus be the basis for a drug against Covid-19. In a massive X-ray screening, the researchers tested almost 6000 known active substances that already exist for the treatment of other...
Michigan's Middle Eastern and North African population face barriers to optimal health
Within southeast Michigan's Middle Eastern and North African community, those who worry about deportation or believe they've been treated unfairly are likely to face more adverse conditions associated with poor health, including food insecurity and financial distress.The MENA people who face several of these barriers are also more likely to report chronic illness and mental health issues as well...
