Wound treatment hydrogel infused with amino acid kills bacteria naturally and promotes cell growth
Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture.....»»
Tracking the virus behind India"s lumpy skin cattle crisis
In May 2022, cattle across India began dying of a mysterious illness. Since then, about 1,00,000 cows have lost their lives to a devastating outbreak of what scientists have identified as lumpy skin disease. The outbreak has severely affected India's.....»»
A frozen chunk of genome rewrites our understanding of bird evolution
An enormous meteor spelled doom for most dinosaurs 65 million years ago. But not all. In the aftermath of the extinction event, birds—technically dinosaurs themselves—flourished......»»
Can savanna emerge in the cold high latitudes and altitudes due to ongoing rapid warming?
Recent studies have shown that rising atmospheric CO2 concentrations and consequential warming may compromise the community structure and functioning of the cold tundra ecosystems. However, in addition to carbon uptake, natural vegetation—particula.....»»
Researchers reveal structure and assembly mechanism of unique module in cellulosome
Cellulosomes are multi-enzyme complexes known for their efficient lignocellulose degradation, which is valuable in bioenergy technique development. The diverse composition and intricate assembly of cellulosomes give them exceptional substrate degrada.....»»
Rice husk can be used as a promising sustainable packaging material
Rice husk, the hard-protective layer that envelopes the inner grain of rice, constitutes approximately 20%–25% of the entire rice structure and produces a considerable amount of by-products. In a study published in the journal, Journal of Bioresour.....»»
Researchers challenge the limits of molecular memory, opening the door to the development of molecular chips
Some molecules respond to external light pulses by changing their structure and holding certain states that can be switched from one to another. These are commonly referred to as photoswitches and usually have two possible states. Recently, however,.....»»
Research team proposes a novel type of acoustic crystal with smooth, continuous changes in elastic properties
In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye that is not focused by the.....»»
Core-shell structural units show outstanding toughening effect for ceramics
Toughening has always been an important research direction of structure ceramics. The addition of secondary phases to the ceramic matrix to prepare composite ceramics is an effective toughening pathway in the field of structure ceramics......»»

Office 2024 for Mac will be available as a one-off purchase
While Microsoft pushes Office 365 subscriptions hard, it has so far retained the option of one-off purchases of new editions – and it has confirmed that this will also be available for Office 2024 for Mac. The other good news is that we’re exp.....»»
CERN measures coupled resonance structure that may cause particle loss in accelerators for the first time
Whether in listening to music or pushing a swing in the playground, we are all familiar with resonances and how they amplify an effect—a sound or a movement, for example. However, in high-intensity circular particle accelerators, resonances can be.....»»
Carbon-based supports for electrocatalysis under industrially relevant conditions
Carbon materials, due to their appropriate physicochemical characteristics such as high surface area, adjustable pore structure, variable morphology, and multifunctional surface properties based on chemical modifications, low cost, and ease of prepar.....»»
Animal hair structure changes from summer to winter to fend off freezing weather, researchers show
Unique adaptations allow wild animals to survive temperature extremes that would quickly kill an unprotected human. For example, certain animals can withstand bitterly cold weather, thanks to the insulating properties of the hollow hairs that make up.....»»
