Mar 5, 2023 · A potential solution could be found in the very shape of the quantum fog itself, according to a 2022 study by researchers from Uppsala University in Sweden. Their experiments on the wave-like nature of something called a Rydberg state revealed a novel way to measure time that doesn't require a precise starting point. Using a high-temperature plasma tunnel, scientists have discovered what it might be like to plumb the depths of Uranus. Sure, we know it would be smelly; but there are other considerations that need to be taken into account when designing a probe that can withstand the rigors therein. So scientists simulated …Living a humble life as a 10-kilogram (22-pound) doorstop at a local farm, the space rock laid around for several decades before being recognized by the scientific community.

In 2013, researchers found that dolphins can recognize the signature whistles of their kin after 20 years spent away from each other.Res. Lett, 2024) The oceanic plateaus are located hundreds to thousands of kilometers from the nearest plate boundary. Yet Gün and colleagues found the plateaus shared deformational and magmatic features that suggest they are being torn apart by pull forces at the Pacific plate's edge, where slabs are being …This idea that cat ownership could be linked to schizophrenia risk was proposed in a 1995 study, with exposure to a parasite called Toxoplasma gondii suggested as a cause. But the research so far has put forth mixed conclusions. Studies have found that being around cats during childhood might make a person more likely to develop …T hey warn current production methods of lab-grown meat could end up being way worse for the environment than beef farming, despite being touted as a sustainable alternative. Their life-cycle assessment of current meat-growing processes – which has yet to be peer-reviewed – found cultured meat production could emit between four to 25 times ...Cryptosporidium is a microscopic parasite. (CDC) Infections from a parasite which can cause long-lasting, severe diarrhoea has seen an "unprecedented and ongoing" surge across the UK.
