Cutting-edge: New and improved drug to counter spinal anesthesia blues during C-sections

(Cactus Communications) Spinal anesthesia for cesarean section deliveries can cause the mother’s blood pressure to drop. To prevent this, physicians routinely administer certain drugs, of which the most common one can lead to undesirable complications in both the mother and the baby. A new study in Chinese Medical Journal shows how a more recent drug that is gaining in use could be the better alternative in terms of reduced complications and also benefit the baby’s neurodevelopment.

Systemic inequalities driving exposure to high indoor air pollution in London

(University College London) Systemic inequalities mean that low-income households in London are more likely to be exposed to higher levels of indoor air pollution, according to a report by UCL researchers.The biggest factors are the quality of housing and the characteristics of the surrounding environment, taking location and levels of outdoor air pollution into account – factors beyond occupants’ control.

Researchers develop new metal-free, recyclable polypeptide battery that degrades on demand

(Texas A&M University) The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.

Artificial color-changing material that mimics chameleon skin can detect seafood freshness

Scientists have designed an artificial color-changing material that mimics chameleon skin, with luminogens (molecules that make crystals glow) organized into different core and shell hydrogel layers instead of one uniform matrix. The findings demonstrate that a two-luminogen hydrogel chemosensor developed with this design can detect seafood freshness by changing color in response to amine vapors released by microbes as fish spoils.

Physicists unveil the condensation of liquid light in a semiconductor one-atom-thick

(St. Petersburg State University) An international team of physicists has shown experimentally for the first time how a Bose-Einstein condensate – tens of thousands of quanta of ‘liquid light’ – is formed in the thinnest monatomic film of a semiconductor crystal. The team includes the head of the Spin Optics Laboratory at St Petersburg University, Professor Alexey Kavokin. This discovery will help create new types of lasers capable of producing qubits – the main integral parts of quantum computers of the future.
