About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most of that helium into carbon and oxygen. It will have swollen to a size large enough to fill the solar system nearly to the current orbit of Mars, and lost almost half of its mass in winds. At this stage the very hot remnant star will ionize the ejected material, l

Lopsided sourdough, cupboards full of toilet paper, or matching trackpants. What does your Australia 2020 scrapbook look like? There will be, for most of us living in Melbourne, no holiday snaps to memorialise this year. No big weddings. No gathering of old friends at the comedy festival. Instead our lives, for much of the past six months, have been spent inside our homes and nodding politely to
Physicist Ivan Maksymov and applied mathematician Andriy Pototsky placed worms on subwoofer in ‘what if’ moment Blasting a speaker to move garden worms in a regional Victorian backyard might sound more like a high school science experiment than a breakthrough in neuroscience.

Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life. By studying both human and mouse brain activity, they report that this process happens in a region of the brain called the hippocampus.
The scientists found that the more curved a toe spring is, the less power the foot inside the shoe has to exert when pushing off from the ground while walking. That means foot muscles are doing less work, and this, the researchers hypothesize, may have consequences such as less endurance and make people more susceptible to medical conditions like plantar fasciitis.
New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions. By using a high-speed stereophotogrammetry system, investigators were able to focus on how the shell shape, body geometry, and body size affect their swimming behavior from a fluid mechanics perspectiv

For the first time, scientists have studied the early effects of time-restricted feeding on the daily periodic oscillations of metabolites and genes in muscle, and metabolites in blood. The findings find that time-restricted feeding does not influence the muscle's core clock, and opens the door to more research on how these observed changes improve health.
Researchers have uncovered the mechanics of how plant cell walls balance the strength and rigidity provided by cellulose with its ability to stretch and compress. This discovery helps explain how plant structures can range from floppy grasses to hard wood trees and is important for understanding dietary fiber properties in nutrition. The findings also have applications in medicine, agriculture and
In a simulation study, researchers showed that limiting global warming to 1.5°C rather than 2°C will mitigate aridification in some regions of the world including the Mediterranean, western Europe, and southern Africa. However, Australia and some parts of Asia were simulated to become wetter rather than drier at both 1.5°C and 2°C of warming. These findings reveal the importance of targeted region

While the disease can be controlled by chemicals, those may be harmful to humans, animals, and the environment and the application can cost millions of dollars to wheat production. Rather than use chemicals, many farmers would prefer to grow wheat varieties that resist stripe rust and the devel
NASA satellites provided a look at the rainfall potential in Hurricane Sally before and after it made landfall in southern Alabama. NASA's Aqua satellite and IMERG analysis were used to analyze the storm's flooding potential.
Does your office look like this? Get more organized. (Wesley Tingey via Unsplash/) What starts with a few innocent bills can—before you know it—become an overwhelming document pile you’re forced to tear through in a panic looking for your lost passport. Despite our reliance on electronic storage, we still need efficient and secure cabinets to store our important personal papers. The beauty of it
Scientists at Tokyo Institute of Technology (Tokyo Tech) have discovered a new alkali copper halide, Cs5Cu3Cl6I2, that emits pure blue light. The combination of the two halide ions, chloride and iodide, gives the material a crystalline structure made of zigzag chains and peculiar properties that result in highly efficient photoluminescence. This novel compound could be readily used to produce rela
For many livestock species, artificial insemination (AI) is standard. But it can be tricky to achieve success the first time, thanks to variability in ovulation timing across the herd.
High-severity wildfires in northern coastal California have been increasing by about 10 percent per decade since 1984, according to a study from the University of California, Davis, that associates climate trends with wildfire.
An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet's geological history.
High-speed cameras can take pictures in quick succession. This makes them useful for visualizing ultrafast dynamic phenomena, such as femtosecond laser ablation for precise machining and manufacturing processes, fast ignition for nuclear fusion energy systems, shock-wave interactions in living cells, and certain chemical reactions.
Let's say you want to purchase a camera, and you're comparing two different advertisements. In one, the font, colors, and layout make the information easy to read. The other has an obscure style that takes more time for you to understand. If you decide to purchase the second camera with the more confusing advertisement, new research out of Rensselaer Polytechnic Institute shows that, over time, yo
An international collaboration of theoretical physicists—including scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) and the RIKEN-BNL Research Center (RBRC)—has published a new calculation relevant to the search for an explanation of the predominance of matter over antimatter in our universe. The collaboration, known as RBC-UKQCD, also includes scientists

Upwards curvature means foot muscles do less work, potentially weakening them over time They may feel comfy, but wearing shoes that curve upwards at the front may be weakening your foot muscles and increasing your risk of injury. This curvature, known as a “toe spring”, is a common feature of many shoes, especially trainers. It helps the front part of the foot to roll forwards when walking or run
