We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers tested a device to convert this ambient energy into energy for electronic devices.

Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.

Social rank may determine whether animals prioritize immediate fitness over long-term health, according to a study. Researchers studied macaques on a Thai island and found that the animals' unusual habit of washing their food is in fact based on social rank. Dominant monkeys quickly brush their food on their fur before eating it, along with mouthfuls of tooth-degrading sand, while lower-ranked monkeys obsessively wash their food in the surf. Citing the disposable soma hypothesis, the researchers suggest that high-ranking macaques are looking to quickly consume energy to mate and fend off challengers. But food-washing monkeys may be preserving their long-term health to produce more offspring over time. The findings could shed light on how the wear observed in the fossilized teeth of early humans relates to social structure.

In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before, according to the results of a new study.

Gold does not readily lend itself to being turned into long, thin threads. But researchers have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.

A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.

The Pyramid of Djoser, the oldest of Egypt's iconic pyramids, may have been built with the help of a unique hydraulic lift system, according to researchers. A new study suggests that water may have been able to flow into two shafts located inside the pyramid itself, where that water could have been used to help raise and lower a float used to carry the building stones.

Scientists say they have identified the main process that formed the moon's atmosphere and continues to sustain it today. The team reports that the lunar atmosphere is primarily a product of 'impact vaporization.'

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the first time a molecular complex -- called CTF18-RFC in humans and Ctf18-RFC in yeast -- that loads a 'clamp' onto DNA to keep parts of the replication machinery from falling off the DNA strand.

Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).

Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.

What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.

Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.

New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.

Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar astrophysics and helps us understand the activity of the Sun, its spot structures and eruptions.

Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?

Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
