A common bacterium can be adapted to convert plastic waste into paracetamol, a study published this week in Nature Chemistry1 reports. Paracetamol, also known as acetaminophen, is widely used to treat pain and fever. It is produced from molecules derived from fossil fuels, but researchers are working to develop processes that use more sustainable source molecules, such as plastic waste. “We’re able to transform a prolific environmental and societal waste into such a globally important medication in a way that’s completely impossible using chemistry alone or using biology alone,” says co-author Stephen Wallace, a chemical biotechnologist at the University of...

For the first time, mice born to two fathers have grown up and produced offspring, scientists in China have revealed. The researchers at Shanghai Jiao Tong University managed to insert two sperm cells - one from each father - into a mouse egg whose nucleus had been removed. A gene editing technique was then used to reprogram parts of the sperm DNA to allow an embryo to develop – a process called androgenesis. The embryo, featuring the genetic material from two fathers, was transferred to a female womb and allowed to grow to term. Finally, the resulting offspring (male) managed...

Image by Gerd Altmann from Pixabay A University of Alaska Fairbanks (UAF) scientist has proposed a “three-dimensional time” theory that replaces the traditional model of one dimension of time and three physical dimensions as the primary fabric of everything. Unlike previously proposed, purely mathematical ‘3D time’ constructs where space emerges as a secondary manifestation, Professor Gunther Kletetschka at the UAF Geophysical Institute says his theory of everything, which could unify quantum physics and gravity, is testable and verifiable. “Earlier 3D time proposals were primarily mathematical constructs without these concrete experimental connections,” Professor Kletetschka explained. “My work transforms the concept from...

n a quest to understand complex speech, scientists inserted what's been dubbed a human “language gene” into mice. Remarkably, the genetic tweak had a profound impact on the little rodents' ability to squeak, revealing astonishing clues about the evolution of vocal communication. Mouse pups that had the human version of the language gene showed different vocalization patterns from their buddies with the usual version mice have. When calling for their mother, their squeaks were higher pitched and featured a different selection of sounds than usual. “All baby mice make ultrasonic squeaks to their moms, and language researchers categorize the varying...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years collapsing on itself, according to new research. An international group of more than 900 researchers studying the expansion of the universe presented their findings on Wednesday during the American Physical Society's Global Physics Summit in Anaheim, Calif. The scientists, who are collaborating on something called the Dark Energy Spectroscopic Instrument (DESI) are studying the history of the universe's expansion out to 11 billion years in the past.

Samples drilled from deep beneath the sea have revealed just how much global sea levels changed following the last ice age. Melting ice caps in North America, Antarctica and Europe caused sea levels to rise quickly as temperatures warmed after the last ice age. But researchers have lacked robust geological data from this period, so how much sea levels climbed was unknown. Now, new geological data show that sea levels rose about 125 feet (38 meters) between 11,000 and 3,000 years ago, according to a study published March 19 in the journal Nature. The findings could help scientists and policymakers...

A prehistoric “factory” discovered in Tanzania could push bone tool-making back by more than a million years, indicating unexpected abstract reasoning capabilities human ancestors displayed in the remote past. According to researchers at University College London (UCL) and the Spanish National Research Council (CSIC), about 1.5 million years ago, hominin hands fashioned the 27 ancient bone tools now preserved as fossils. The find represents the earliest significant bone tool collection ever found, particularly notable for the systematic, factory-style production methods they display. Previous evidence indicates that hominins produced stone tools for over a million years, although archaeologists had previously never...
