Educators should have not have "high"' confidence in the quality of existing relationship education programs, because there is a lack of robust evaluation, experts have warned.

The inconspicuous sea sponges are Earth's oldest multicellular animals and have filtered the oceans for nearly 900 million years, long before the first plants appeared on land. New research appearing in the journal Fishery Bulletin, published by the National Oceanic and Atmospheric Administration, indicates that their growth depends on their oxygen supply in a manner similar to more complex animals such as fishes.

A paper published in People and Nature explores how government policymakers can include a wide range of farmers in the design of new Environmental Land Management (ELM) schemes, using different engagement strategies to work with individuals who may be harder to reach.

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is expanding its ability to more accurately identify where fast radio bursts (FRBs) are coming from. The organization is constructing a new radio telescope outrigger at the SETI Institute's Hat Creek Radio Observatory (HCRO), site of the Allen Telescope Array (ATA). The outrigger will work with the main CHIME instrument in British Columbia's Okanagan Valley and enable CHIME-detected FRBs to be precisely localized on the sky. In addition to the new radio telescope at HCRO... Читать дальше...

Efforts to mitigate the potentially harmful effects of fracking have traditionally been divided along two fronts—those that primarily focus on protecting the environment and wildlife, and those that focus on protecting humans and domestic animals.

Mycobacteria are a group of pathogenic bacteria that cause diseases like leprosy and tuberculosis in humans. Now, a new study by scientists at Hiroshima University finds that mycobacteria are associated with red blood cells at lung infection sites, an interaction that has escaped scientific notice for 140 years since the discovery of the organism causing tuberculosis.

ETH Pioneer Fellow Martin Hofmann has developed a method to produce high-quality plant-based meat alternatives. His research on the flow properties of soft materials enables him to imitate the marbling of real steaks.

Faster, more energy-efficient ICT, or sensors to detect anything between beginning fruit rot and microscopic cracks in glass fibers: photonic technology holds great promises for the future. To deliver on those promises, a European consortium led by TU/e researchers takes the next step. The INSPIRE project uses a novel printing method to enable mass fabrication of hybrid photonic chips. These combine multiple technologies to create new possibilities for applications.

When you do something for which you are to blame, how long are you actually blameworthy for your misdeed? Does culpability evaporate once you are forgiven? These are among the questions one Florida State University philosopher is tackling in a new article published this winter in the international journal Philosophical Studies.

Lawrence Livermore National Laboratory (LLNL) scientists have simulated the hydrogen storage reactions in a promising material and discovered why hydrogen uptake slows as the material absorbs hydrogen, providing insight that could be used for improvements.

As comets approach the Sun, they release gas and dust known to astronomers as cometary activity. For comets passing near or inside Earth's orbit, this activity slows over successive orbits. University of Oklahoma astronomer Nathan Kaib has found this same comet-fading phenomenon occurs as comets make repeated passages through the more distant region beyond Saturn.

Feeling unhappy? Go find a city park—the bigger the better—and try taking a walk outdoors.

The majority of commercial chemicals that enter the market in the United States every year have insufficient health and safety data. For pesticides, the U.S. Environmental Protection Agency uses a variety of techniques to fill data gaps in order to evaluate chemical hazard, exposure and risk. Nonetheless, public concern over the potential threat that these chemicals pose has grown in recent years, along with the realization that traditional animal-testing methods are not pragmatic by means of speed, economics or ethics.

In a recent study published in Nature Communications, international scientists have taken on a persistent problem in climate science: near-term climate evolution.

Inadequate and imbalanced fertilizer application is a well understood root cause of stagnating and inconsistent yields across sub-Saharan Africa (SSA). What is required is the effective delivery of more made-to-measure approaches that can counter the variability farmers face in their fields from season to season.

Biodiversity losses in countries with smaller, less-developed economies, impact large, developed economies, according to a new study.

A research team led by Prof. Wang Bo from Yunnan Observatories of the Chinese Academy of Sciences has explained the formation of millisecond pulsars (MSPs) with long orbital periods by accretion-induced collapse of white dwarfs.

Researchers from Tohoku University modeled the process by which public opinions evolve regarding the development of a geothermal power plant.

Female CEOs face more aggressive questioning from male analysts during earnings conference calls, a new study reveals.

New views from ESA's Mars Express reveal fascinating ice-related features in Mars' Utopia region—home to the largest known impact basin not only on the Red Planet, but in the Solar System.

Researchers from UNSW Sydney have confirmed the likely disappearance of platypuses from the Royal National Park, based on results of recent environmental DNA (eDNA).

Invasive exotic species are considered one of the main causes of the current biodiversity crisis. In recent years, humans have introduced 200 species of ant from outside of their natural area of distribution and some of them have become invasive. Such is the case of the Asian needle ant, Brachyponera chinensis, which has seen its area of distribution greatly expand in the last 80 years.

A new study in The Journal of Organic Chemistry refutes a theory on the transfer of light energy.

You can't see it, but different substances in the petals of flowers create a "bulls-eye" for pollinating insects, according to a Clemson University scientist whose research sheds light on chemical changes in flowers which helps them respond to environmental changes, including climate change, that might threaten their survival.

Microalgae, algae that cannot be seen by the naked eye, absorb carbon dioxide and produce oils that can be used as biofuels. These biofuels, which can be carbon negative, offer promise as an alternative to conventional fossil fuels. However, the biological processes that allow these microalgae to produce oils are not fully understood.
