By drawing in a bit of sweat, a patch can reveal how much cortisol a person is producing. Cortisol is known as the stress hormone but is involved in many important physiological functions.

Researchers have created the fastest human-made spinning object in the world, which they believe will help them study material science, quantum mechanics and the properties of vacuum.

Named for the mythical god with two faces, Janus membranes — double-sided membranes that serve as gatekeepers between two substances — have emerged as a material with potential industrial uses.

A new study showed for the first time that video games, in combination with fitness coaching and a step tracker, helped overweight children lose weight, lower their blood pressure and cholesterol and increase their physical activity.

Not long ago, getting a virus was about the worst thing computer users could expect in terms of system vulnerability. But in our current age of hyper-connectedness and the emerging Internet of Things, that’s no longer the case. With connectivity, a new…

Researchers is taking solar sailing to the next level with advanced photonic materials. This new class of materials could be used to steer reflected or transmitted photons and enable near-Earth, interplanetary and interstellar space travel.

This summer, NASA’s Parker Solar Probe will launch to travel closer to the Sun, deeper into the solar atmosphere, than any mission before it. Cutting-edge technology and engineering will help it beat the heat.

An international team of scientists has discovered a new, exotic form of insulating material with a metallic surface that could enable more efficient electronics or even quantum computing. The researchers developed a new method for analyzing existing c…

Scientists are helping to answer long-held questions about a technologically important class of materials called relaxor ferroelectrics.

A new type of flow battery that involves a liquid metal more than doubled the maximum voltage of conventional flow batteries and could lead to affordable storage of renewable power.

Radiofrequency electromagnetic fields may have adverse effects on the development of memory performance of specific brain regions exposed during mobile phone use, suggests a recent study involving nearly 700 adolescents in Switzerland.

Scientists have developed a new method to enable miniature drug-filled nanocarriers to dock on to immune cells, which in turn attack tumors.

Degradation rates of oil were slower in the dark and cold waters of the depths of the Gulf of Mexico than at surface conditions, according to an international team of geoscientists trying to understand where the oil went during the Deepwater Horizon oi…

With the hope of providing water resource managers with better tools to help keep aquifers healthy, a team of scientists are using the latest space technology to look underneath Earth’s surface to measure this precious natural resource.

Researchers have shown that it is possible to train artificial neural networks directly on an optical chip.

Almost every golfer knows the feeling. Minutes after a picture-perfect drive down the fairway, a cascade of inexplicable missed putts leads to a disappointing triple bogey.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

Metallic glasses are an exciting research target, but the difficulties associated with predicting how much energy these materials release when they fracture is slowing down development of metallic glass-based products. Recently, researchers developed a…

for the first time, an open-source computing tool can, simply and intuitively, calculate the CO2 emissions in each phase of a building project, in order to obtain a global picture of its carbon footprint from its conception and to help decide every var…

Working to address ‘hotspots’ in computer chips that degrade their performance, engineers have developed a new semiconductor material, defect-free boron arsenide, that is more effective at drawing and dissipating waste heat than any other known semicon…

A new theoretical study explains previous mystifying experimental results, in which coupled charged particles moved in exactly the opposite direction to that predicted. This apparently contradictory phenomenon is associated with the bandgap in dual-lay…

Researchers have succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET). Observations by CALET are expected to reveal the mysteries of c…

Scientists have designed new proteins that can self-assemble into the complex structures underlying biological organisms, laying the groundwork for leading-edge applications in biotechnology. The researchers created and developed the proteins with a sp…

Scientists show that a quantum computer is less in thrall to the arrow of time than a classical computer.

Could robots soon help rescue crews save the survivors of a natural disaster? Such a mission would require that the robots be able to determine, on their own, which tasks to perform and in what order to perform them. Researchers have shown, for the fir…

There is good news for amateur bakers of cakes, muffins and pastries made in extravagant shapes and small and medium-sized baking businesses. Molds will cease to be a problem if the system designed by a research group progresses. This system manufactur…

Climate lobbying is big business. A new analysis shows that between 2000 and 2016, lobbyists spent more than two billion dollars on influencing relevant legislation in the US Congress. Unsurprisingly, sectors that could be negatively affected by bills …

A new mission called HaloSat will help scientists search for the universe’s missing matter by studying X-rays from hot gas surrounding the Milky Way galaxy.

Your everyday permanent markers, glue sticks and packing tape may offer a surprisingly low-tech solution to a long-standing nuisance in the manufacturing industry: Making soft and ductile, or so-called ‘gummy’ metals easier to cut.

A sample of ancient oxygen, teased out of a 1.4-billion-year-old evaporative lake deposit in Ontario, provides fresh evidence of what the Earth’s atmosphere and biosphere were like during the interval leading up to the emergence of animal life.
