Plant-derived essential oils (EOs) find applications in various industries, such as detergents, cosmetics, pharmacology, and food additives. Moreover, EOs have an exceptional safety profile, and their numerous bioactivities greatly benefit human health. Beyond these benefits, EOs have also been found to illicit insect-repellent responses by inducing neurotoxic effects.

Blood vessels engineered from stem cells could help solve several research and clinical problems, from potentially providing a more comprehensive platform to screen if drug candidates can cross from the blood stream into the brain to developing lab-grown vascular tissue to support heart transplants, according to Penn State researchers.

A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.

A Purdue University-led research team has begun translating the complex molecular language of petunias. Their grammar and vocabulary are well hidden, however, within the countless proteins and other compounds that fill floral cells.

Every day, more children discover they are living in a climate crisis. This makes many children feel sad, anxious, angry, powerless, confused and frightened about what the future holds.

A new variety of rice that is adapted to life in low-phosphorus soils, that contains an exceptionally large amount of zinc and that was developed specifically for the conditions in Madagascar where it is grown, has recently been certified in the country.

Tropical Heliconius butterflies are well known for the bright color patterns on their wings. These striking color patterns not only scare off predators—the butterflies are poisonous and are distasteful to birds—but are also important signals during mate selection.

Touchscreens have long been integral to our everyday life—humans use them to work, play, talk with loved ones and snag Lightning Deals on Prime Day. In recent years, they've shown potential for the animal kingdom as well, leading to a growing body of academic research and a proliferation of consumer products promising to leverage technology to enhance our relationships with our pets.

A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study led by the University of Birmingham.

While much ink has been poured over China's economic growth in recent decades, the contributions of Chinese women often receive less attention. With the pressure of the "three-child policy", being a mother isn't a mere personal choice, it's a part of national demographic strategy. To navigate their lives, many Chinese mothers are now turning to what has been referred to as "mumpreneurship". A January 2024 search for "妈妈创业" (the term in Chinese) showed 69.9 million results on Baidu, China's primary search engine... Читать дальше...

Rising temperatures, changes in major currents, oxygen depletion at great depths: the Gulf of St. Lawrence has undergone major changes in its environmental conditions in recent decades. That has put many species in danger and, as a consequence, made them more sensitive to the effects of fishing.

Can salt marshes serve as a natural solution for flood protection? Researchers of the project "Living Dikes" transported 62 big blocks of salt marshes, containing soil and vegetation, from the coast of Friesland to the Delta Flume at Deltares. After four weeks of exposure to extreme waves, almost the entire salt marsh is still standing there.

The use of water contaminated with higher than recommended levels of arsenic could pose a serious health risk to millions, a new study from the University of Sheffield has found.

Assumptions, misconceptions, and stereotypes—no one wants to be judged by how they look or where they're from. But for many Black African students, that's their reality and it's taking a serious toll on their well-being and sense of belonging.

As the nation braces itself for another pivotal presidential election year, the spotlight on gun control intensifies—one of America's most contentious issues. Shedding light on this debate, new research by Dr. Michael Nelson, emeritus professor of economics at The University of Akron, and Dr. Rajeev Goel, professor of economics at Illinois State University, unveils a surprising revelation: female legislators wield a significant influence on the trajectory of gun laws across the United States.

Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey round the sun, ahead of Mars and in the same orbit.

It takes two to tango, but in the case of brown dwarfs that were once paired as binary systems, that relationship doesn't last for very long, according to a recent survey from NASA's Hubble Space Telescope.

A gene associated with courtship behavior in fruit flies does not operate the same way in two different fruit fly species, a new study finds. The work demonstrates that conserved genes—the same genes found across species—do not necessarily have the same function across species.

Cerium is a rare Earth metal that has numerous technological applications, for example, in some types of lightbulbs and flat-screen TVs. While the element is rare in Earth's crust, it is slightly more abundant in the universe. However, much is unknown about how it is synthesized in stars.

Astronomers have revealed that a brilliant supermassive black hole is not living up to expectations. Although it is responsible for high levels of radiation and powerful jets, this giant black hole is not as influential as many of its counterparts in other galaxies.

Researchers from the University of Tsukuba examined the developmental processes and reproduction-related behavior of 8 of the 11 families of Dermaptera (earwigs) in detail and compared with those reported in previous studies. The results confirmed that Dermaptera is a polyneopteran order, and features such as caudal forceps and elaborate maternal care for eggs and young larvae emerged in parallel within the order during evolution.

A research group led by Prof. Jiang Haihe from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has designed a 6-hole microstructure anti-resonant air-core fiber (AR-HCF) with a larger core diameter of 78 μm.

To effectively prevent liver abscesses in cattle, it is crucial to gain a complete understanding of the development of this condition and the bacteria responsible for causing the infection.

In a leap toward managing the ecological challenge posed by alien plant species, a recent study outlines a methodology for integrating and harmonizing data on plant invasions across Australia.
