An international team of experts undertaking fundamental research has developed a way of using polyethylene waste (PE) as a feedstock and converted it into valuable chemicals, via light-driven photocatalysis.
The Great Wall of China used to be much greater. What stands today is only a fraction of the expansive fortifications built on the country’s northern borders starting more than 2000 years ago and then eroded by time. But many sections of the remaining walls seem to be getting preservation help from an unlikely source: thin layers of bacteria, moss, lichen, and other organisms known as...
Fully grown tyrannosaurs were fearsome predators. With powerful jaws and piercing teeth, they could kill huge herbivores larger than themselves. But young tyrannosaurs ate different—and much smaller—prey, paleontologists report today in Science Advances . A new fossil with remains of a last supper confirms these carnivores switched their diet as they grew...
Rare preserved stomach contents show young dinosaur feasted on drumsticks of speedy turkey-sized creatureA remarkable fossil preserving the last meal of a young tyrannosaur has been discovered in Canada, revealing the dinosaur had a taste for prehistoric fast food.While tyrannosaurs were some of the most fearsome dinosaurs to roam the planet, with adults boasting massive bodies, huge heads and...
Scientists have made a rare and extraordinary fossil find in Alberta: a young tyrannosaur, with remains of baby dinosaurs in its...
Rice is crucial for global food security, providing sustenance for half of the world's population. Its production, particularly influenced by environmental factors during the heading-flowering stage, affects crucial growth traits. Traditional phenotyping methods are inefficient for large-scale analysis, necessitating advanced, accurate monitoring solutions.
C4 plants are distinguished by a unique leaf structure known as Kranz anatomy, characterized by inner vascular bundle sheath cells and outer mesophyll cells. This specialized arrangement confers C4 plants with several advantages over C3 plants, including higher photosynthetic rates and superior nitrogen and water use efficiency.
A recent study, published in Science China Earth Sciences and led by geologist Bo Wan from the Chinese Academy of Sciences' Institute of Geology and Geophysics, connects the Tethyan plate tectonic movements to changes in Earth's surface environment. The work reveals Earth's multi-sphere interactions.
A synthesis study published in Science China Earth Sciences is led by Prof. Yong-Fei Zheng at University of Science and Technology of China. It focuses on the thermal and tectonic evolution of regional metamorphism at convergent continental margins based on a systematic outline of metamorphic temperature (T), pressure (P), and time (t) information on high-grade metamorphic rocks along the Central...
Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire risk and allocate resources accordingly. A new study contributes scientific expertise to this effort.
Before researchers can develop targeted drugs, they need to know exactly how a disease works. Biochemist Bert Beerkens created molecules that allow them to find out. He used caffeine as the basis for new molecules that enable research into certain receptor proteins on cells.
A landmark study has shown that severe asthma can be controlled using biologic therapies, without the addition of regular high-dose inhaled steroids which can have significant side effects.
In hopes of producing concrete structures that can repair their cracks, researchers are putting a new twist on an old trick for improving the durability of concrete. Fiber reinforcement has been around since the first masons were mixing horsehair into their mud. But this research team is taking this method to the next level by turning reinforcing fibers into a living tissue system that rushes...
New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles...
A challenge among three housemates to identify species around their inner-Brisbane home has resulted in an academic research paper, showcasing the rich biodiversity in urban landscapes.
Formaldehyde's toxicity was presumed to derive from its ability to crosslink DNA, but that happens only at huge doses. Recent discoveries that formaldehyde is found in the body in small amounts led a team to investigate its natural role. They found that formaldehyde regulates epigenetic modification of DNA, interfering with an enzyme that carries methyl groups used to modify DNA. Too much...

Exclusive breastfeeding for the first six months of life is proven to protect both mother and child health. According to the World Health Organization (WHO), between 2015 and 2021, 48% of mothers exclusively breastfed, meaning that their babies were not given any other food or liquids. However, this figure is based on data collected from surveys which report what a child was given in the previous...
Record breaking marine heatwaves will cause devastating mass coral bleaching worldwide in the next few years, according to a coral reef scientist.
Researchers have developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths. This pioneering work represents a significant advance in the field of photonics, with implications for telecommunications, metrology, and other high-precision applications.
An international team of researchers has visualized the structure of the so-called ASC speck.
In order for immune cells to do their job, they need to know against whom they should direct their attack. Research teams a have identified new details in this process.
