The cost of playing community sports in Australia is far higher than previously understood, with a new national study led by Federation University finding families spend an average of $4,567 per child each year to keep their children playing sports.
When plants are attacked by herbivores or pathogens, they must respond rapidly while also preparing for potential future attacks. Calcium, a cellular second messenger, and the plant hormone jasmonic acid play important roles in this response. Within seconds of an injury, the plant generates calcium waves that relay information about the attack. At the same time, the synthesis of jasmonic acid is initiated in the chloroplast, triggering, through several intermediate steps, the expression of defen

Two SUNY Polytechnic Institute (SUNY Poly) College of Business faculty members are exploring how integrating ethics and values throughout accounting and business education can better prepare students to recognize and prevent fraud in the workplace.
One of the central ideas in modern physics is the phase transition
Two administrations, the Biden administration and the second Trump administration, reached opposite conclusions about whether vehicle emissions standards should be rolled back. These conclusions came from different assumptions, including whether avoiding air pollution has value to society and the degree to which car buyers value future fuel savings from getting a more efficient vehicle. Both assumptions matter, and disagreement over either accounts for hundreds of billions of dollars in the gove
A collaborative research team has successfully visualized in real space the ultrafast optical modulation of hyperbolic phonon polaritons (HPhPs) in a van der Waals heterostructure composed of hBN and WS2. The research is published in the journal Nano Letters, and was led by Kazuki Kamada of the Institute for Molecular Science (IMS) and Osaka Metropolitan University, along with Dr. Jun Nishida, assistant professor at IMS, and Takashi Kumagai, associate professor at IMS.
As dogs age, many develop more than one chronic health condition. New research from Texas A
Metal-insulator transitions (MITs), in which a material changes from a metallic state with low resistivity to an insulating state because of a change in an external parameter, such as temperature, pressure or an electric field, are a central topic in fundamental physics research.
Scientists have often wondered about species that are unique to Antarctica. But the focus has mainly been on animals, like feathery penguins. CIRES researchers wanted to dig deeper
Cooling from air conditioning saves lives
The question is no longer whether microbial foods can be made. The question now is who can be first to turn them into an industry. KAIST researchers have analyzed the conditions required for the microbial food industry to succeed across manufacturing, markets and regulation, and have proposed growth strategies for the next-generation protein industry.

Fast, on-farm genetic testing for cattle is practical and achievable for northern producers, according to University of Queensland research. In partnership with Meat
Swapping out one letter in a word can entirely change its meaning. Similarly, swapping one atom in a molecule can completely change its identity. A group of chemists at the University of Chicago has demonstrated a new way to make a single-atom edit to a molecule without changing any of its other components. The innovative method can be used to make a family of molecules known as pyrroles, including many widely used medicines, and is significantly simpler, faster and more cost-effective than prev
How protective is air conditioning in preventing deaths amid soaring temperatures and record heat levels? Yale researchers found that AC use cut the number of annual heat-related deaths by half in the U.S., saving more than 5,000 lives a year. However, while AC is a highly effective heat adaptation tool, its protective effects level off once use passes a certain point. On days of extreme heat, risk levels tick up even with use.
You may check your phone before deciding what to wear tomorrow. Plants do something similar: they carry an internal gadget called a
As Europe burns, many cities are trying to cut emissions, upgrade buildings and rethink how energy is produced and used. However, there is a recurring challenge: getting people to participate in and accept the solutions needed to bring about the transformation. From this perspective, community engagement is often described as the weakest link in sustainable urban development.
Despite protections, blue whales remain endangered, primarily because of the risk of collisions with ships. MBARI
Emissions from aircraft that use leaded aviation gasoline are a significant source of environmental pollution in neighborhoods near regional airports, according to a new study by researchers at Oregon State University and Portland State University. The findings were published in Communications Sustainability.
Aerosols have a profound influence on air quality, human health, clouds and climate, but new particle formation in the atmosphere has remained a scientific conundrum. Large fractions of airborne fine particulate matter consist of secondary organic aerosols (SOA) formed by gas-to-particle conversion of organic precursor molecules in the atmosphere. The growth rates of these atmospheric nanoparticles, however, have remained enigmatic: They are often smaller and less dependent on condensable vapor
Artificial intelligence can create realistic depictions of just about anything, but that does not mean advertisers should lean on the technology, according to a study led by University of Mississippi professors.
When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth
Resources such as sea level rise viewers, heat maps and flood prediction services are crucial tools in a changing climate. NASA Earth Observations (NASA EO) datasets provide important information on these and other natural hazards, but many communities that may benefit from these tools face barriers to accessing them.
The way Australians consume news has been changing for the past 30 years, ever since internet use became widespread.
A new National Bureau of Economic Research working paper from the University of California San Diego shows that wildfire damage can have long-term economic consequences for households, resulting in income losses, resident relocation and slow rebuilding for several years after a fire.
The tide came in last week carrying thousands of dead sardines onto South Africa
Fermented cocoa occasionally exhibits off-flavors that can compromise the quality of chocolate and other cocoa products. But what causes these undesirable flavors? Researchers at the Leibniz Institute for Food Systems Biology at the Technical University of Munich have now shown that overfermentation of cocoa beans can cause smoky, leathery and cheesy off-flavors. Smoky flavors, therefore, are not necessarily attributable to smoke contamination.
Growth or immune response? Higher organisms must constantly balance these two priorities. As in humans, hormones regulate this balance in plants. Researchers at the Technical University of Munich (TUM) have discovered a mechanism by which plant steroid hormones can inhibit immune responses and thereby make resources available for growth.

Forecast storms in the Grand Canyon on Monday threatened efforts to find more than a dozen people missing after flash floods over the weekend, the National Park Service (NPS) said, with two bodies already recovered.
Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the year. Short-term variations in temperature, winds, ocean convection and water salinity within a certain region can also affect how much ice can reform or melt.
August always feels like one long Sunday to me. It is also a time of year when parents across Canada begin the ritual of preparing their children for September.
