New quantum encryption method prevents ciphertext from being cloned

Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the information is locked inside a math problem that would take a modern computer thousands of years to solve. However, if someone builds a powerful enough computer, that security breaks.

How to keep the Earth habitable when the sun dies

In a billion years, the sun will start to run out of fuel and expand to become a red giant. Earth’s oceans and atmosphere will be burned away, and Earth will likely be engulfed by the sun altogether. The sun will then shrink to a dim white dwarf, and all light and warmth in the […]

Zodiacal dust in exoplanetary systems could hinder our search for life on other worlds

If you’ve ever been under a dark sky in the early morning before dawn, you may have seen a faint glow, almost like a column of light rising from the east. It’s sometimes known as the false dawn because it appears before true dawn. It can also appear in the west after sunset, though it […]

Light controls nanoscale ‘bubble’ domains in a ferroelectric crystal

Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, sensors and future computing technologies.

Simulations hint at a hidden population of companionless black holes

So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, most exist on their own.

Astrobiologist uses Apollo lunar samples as mirror onto early Earth

Roll back the tape of Earth’s history, and geologists and astrobiologists remain perplexed about the environmental conditions on early Earth. That’s because conventional pathways for understanding Earth’s history have been lost to time owing to the planet’s active geology and atmospheric weathering.

Spaceflight could change how astronauts swallow, eat and drink in subtle ways

Imagine trying to swallow a sip of water while your face feels stuffed with congestion, your sense of taste is dulled and your body is floating 250 miles (400 kilometers) above Earth.

Ultrafast X-ray flashes partially reverse the damage they cause, enabling brighter, more accurate imaging

The interaction between X-rays and matter can be actively controlled, according to an international research team led by the University of Hamburg and SLAC National Accelerator Laboratory that has succeeded in producing bright X-ray images with significantly less damage. In an article published in Nature Communications, the researchers report using ultrafast pulses that partially reverse […]

Study lays groundwork for classifying lunar soil

As we move closer to supporting a sustainable human presence on the moon, researchers are investigating how its soils can provide valuable resources and even grow food. An article in the Soil Science Society of America Journal proposes a classification framework to help scientists better understand lunar soils. This emerging science of “planetary pedology,” the […]

Pluto’s hazy atmosphere may be collapsing as it moves farther from the sun

Pluto is on an icy march away from the sun. In 2114, it will turn back, but until then, its elliptical orbit will carry it to colder and darker parts of the outer solar system. This is Pluto’s first time entering the outer solar system since its 1930 discovery, and along this journey, its atmosphere […]

Key principle to boost efficiency of artificial photosynthesis and next-generation semiconductors

A research team led by Taeyeon Kim, a professor in the Department of Chemistry at Sungkyunkwan University, in collaboration with a team from Yonsei University, has identified a new principle that controls charge separation, a phenomenon that plays a central role in both plants’ generation of electrical energy (photosynthesis) and next-generation molecular semiconductor devices.

A 21-hour dip could help explain Tabby’s star’s decade-long dimming mystery

Since 2016, an ordinary-looking F-type star called KIC 8462852, nicknamed Tabby’s star, has behaved anything but ordinarily. In a new study published in the Monthly Notices of the Royal Astronomical Society on July 6, researchers revisited this star to find out what is really causing its irregular dimming.
