Scientists document how essential oils can be used as natural fungicides
Essential oils are concentrated, phytonutrient-rich extracts that capture the scent and flavor of plants. They are usually obtained through distillation or mechanical methods like cold pressing. Essential oils are known for their many uses, such as in aromatherapy, where they are said to help relieve pain and reduce stress and anxiety. Some of these useful natural […]

These phytochemicals can improve the biochemical composition and drought tolerance of rice
Antioxidants are important to human health because they help protect the body from free radicals. These harmful molecules are highly reactive and unstable because of the presence or absence of an unpaired electron on their surface. Oxygen-containing free radicals can attack macromolecules inside the body — including cell components like proteins and DNA — causing cellular […]

Testing for a commensal gut bacterium could help identify people at risk of severe COVID-19
A new study suggests that the composition of gut microbiota could help predict COVID-19 severity. Researchers at the University of Massachusetts Medical School (UMMS) examined stool samples from COVID-19 patients and found that those who were critically ill had altered gut microbiomes. The researchers also identified a commensal bacterium called Enterococcus faecalis as a strong predictor of COVID-19 severity. E. faecalis is a symbiont with a potential to […]

Antimicrobial compound in seaweed can be used to develop self-cleaning surfaces, new research finds
Seaweed is known for being the best dietary source of iodine and for providing many other health benefits. But according to researchers at Unilever, seaweed can also be used to develop self-cleaning surfaces. After more than a decade of studying the chemical components of seaweed, Unilever announced on Jan. 5 that it has developed a new technology that could harness […]

Just like other coronaviruses: Study suggests seasonal changes affect Covid-19 transmission
Increasing ultraviolet (UV) levels in the environment can decrease the spread of the Wuhan coronavirus (COVID-19), reports a new a study published in the journal PNAS. According to its authors, this suggests that the disease has a seasonal pattern (like all other coronaviruses), and understanding this pattern could help improve global response to the pandemic. They remained politically […]

Bats can anticipate their prey’s movements by building predictive models on the fly, says new study
Despite possessing better vision than humans at night, some bats prefer to use their advanced hearing to hunt for food. These nocturnal creatures manufacture sounds and rely on the echoes those sounds make while bouncing off objects to navigate in the dark and find their prey. This ability, known as echolocation, is a subject of particular interest […]

Do you have a median artery? Researchers say it’s proof humans are still evolving
Researchers say humans are still evolving, and they’re evolving at a faster rate than at any point within the past three centuries. The increased prevalence of a structure known as the median artery — which typically regresses in the second month of gestation — in people born by the end of the 20th century is proof of […]

Exploring the potential of using essential oils to control bipolaris leaf spot in maize
Researchers at the Federal University of Tocantins in Brazil evaluated the efficacy of essential oils derived from Ocimum pupuraceus, Cymbopogon nardus, Cymbopogon citratus and Lippia sidoides in inhibiting Bipolaris maydis mycelial growth and conidial germination. They reported their findings in an article published in the Journal of Medicinal Plants Research. Recently, research institutions have been emphasizing the use of alternative […]

How do bacteria populations travel through soil layers?
Soil bacteria are important components of the ecosystem. They help improve soil structure and aggregation, as well as recycle soil nutrients and water. Soil bacteria also serve as decomposers that consume carbon compounds and provide large quantities of nitrogen to plants. Nitrogen is a major component of chlorophyll and is essential for the production of amino acids, which […]

Scientists discover protein that allows soil bacteria to generate electricity in microbial fuel cells
Bacterial cells are only about one-tenth the size of human cells. Despite being considerably smaller, bacteria have more complex respiratory mechanisms than humans. And while higher animals produce carbon dioxide when they breathe, some bacteria can generate an electric current when they “exhale.” In a new study published in the journal Nature Chemical Biology, researchers from Yale […]
