Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside the bacterium transports the substance to the 'elevator' and unloads its cargo there. The freight elevator transports it to the inside of the cell, in other words to another floor. Read more ›

A groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease and climate change. The study challenges the long-standing belief about the unpredictability of evolution, and has found that the evolutionary trajectory of a genome may be influenced by its evolutionary history, rather than determined by numerous...

Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the gaps between the rings. The detailed analysis is consistent with abundant solid iron grains complementing the dust composition. As a result, the disk likely harbors metals and minerals akin to those in the Solar System's terrestrial planets. It offers a... Read more ›

Mycelial fibers, the fibrous cells found in fruiting mushroom bodies, have gained momentum as a sustainable material for making faux-leather and packaging owing to their excellent formability. Recently, a team of researchers has found a simple way of obtaining mycelial fibers, called 'mycelial pulp,' from fruiting mushroom bodies and bleaching them using sunlight while keeping their mycelial structures intact.

Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviors, such as being disengaged and disinterested in activities, seeking more intense stimulation in an environment, or being overwhelmed by sensations like loud sounds or bright lights, according to recent data.

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development. Read more ›

To encourage fruit and vegetable consumption among youth, experiential food education programs such as gardening and cooking lessons have increased across both community and school settings. A recent research article revealed how this early learning positively influenced food decisions as children grew older. Read more ›

Hydrogen energy has emerged as a promising alternative to fossil fuels, offering a clean and sustainable energy source. However, the development of low-cost and efficient catalysts for hydrogen evolution reaction remains a crucial challenge. Scientists have recently developed a novel strategy to engineer stable and efficient ultrathin nanosheet catalysts by forming Turing structures with multiple nanotwin crystals. This innovative discovery paves the way for enhanced catalyst performance for green hydrogen. Read more ›

The construction industry as a CO2 sink? Researchers are working on this. By incorporating biochar into concrete, they are exploring the potential of CO2-neutral or even CO2-negative concrete. For optimal applicability, they process the biochar into pellets and use them to replace conventional aggregates. Read more ›

Climate change could pose a big risk to Australians' reproductive health with a new, large-scale study revealing a possible link between extreme bioclimatic exposure during pregnancy and babies' birthweights for gestational age. Researchers examined more than 385,000 pregnancies in Western Australia between 2000 and 2015, from 12 weeks prior to conception until birth. Read more ›

To address natural resource scarcity, pollution, and other harmful effects of climate change, some scientists and policymakers emphasize the adoption of input-efficient technologies like water-saving devices and fuel-saving stoves. Proponents often refer to these input-efficient technologies as 'win-win,' for the benefits to their users and to the environment, and lament their low adoption rates by consumers, in what they call an 'efficiency paradox.' A new paper examines this paradox and... Read more ›
