Did you know that a single strand of hair can reveal a person's age, gender, race, and even their geographical origin? It's true! And thanks to advancements in forensic science, hair analysis is becoming an increasingly powerful tool for solving crimes and identifying perpetrators. One of the most exciting innovations in hair analysis is the use of mitochondrial DNA. Unlike nuclear DNA, which is only present in a person's cells, mitochondrial DNA is found in hair shafts and can survive for hundreds of years. This means that even if a hair sample is old or degraded, forensic scientists can still extract DNA and use it to create a genetic profile of the individual it came from. But DNA isn't the only thing that hair can tell us. Chemical analysis of hair can also reveal a person's exposure to environmental toxins, drugs, and even nutritional deficiencies. This information can be used to build a profile of an individual's lifestyle and habits, and can be especially useful in cases of drug-related crimes. Hair analysis has also been used to solve historical mysteries, such as the identity of the "Elephant Man," Joseph Merrick. By analyzing strands of Merrick's hair, scientists were able to determine that he suffered from a rare genetic disorder known as Proteus syndrome. One of the pioneers of hair analysis is Dr. Victor B. Fuchs, who developed the technique for detecting lead poisoning in children in the 1970s. More recently, Dr. David Wong and his team at the University of California, Los Angeles, developed a saliva-based diagnostic tool that identifies early-stage cancers. Both Fuchs and Wong have made significant contributions to the field of hair analysis. So what are you waiting for? Dive into the fascinating world of forensic hair analysis and discover all the amazing things that a simple strand of hair can tell us about ourselves and the world around us!

Scotland has become the first country to ban desflurane, an anaesthetic gas with a global warming potential 2,500 times greater than carbon dioxide, from its hospitals due to its environmental threat. The move would cut emissions equivalent to powering 1,700 homes a year. UK hospitals have already cut down, with over 40 hospital trusts in England and some in Wales having stopped using it. NHS England will introduce a similar ban from 2024. Anaesthetists have switched to safer alternatives, but more needs to be done to reduce the NHS's carbon footprint.

Electronic waste is not just trash, it's a treasure trove of precious metals like gold! Researchers at the University of Cagliari and Imperial College London have found a way to extract gold from electronic waste and use it as a catalyst in making medicines. This not only prevents gold from being lost in landfills but also reduces our dependence on environmentally harmful mining practices.

New research has identified gold-based compounds that could treat multidrug-resistant "superbugs", with some effectiveness against several bacteria. Antibiotic resistance is a global public health threat, and the development of new antibiotics has stalled. Gold metalloantibiotics, compounds with a gold ion at their core, could be a promising new approach. Dr. Sara M. Soto Gonzalez and colleagues studied the activity of 19 gold complexes against a range of multidrug-resistant bacteria isolated from patients. The gold compounds were effective against at least one bacterial species studied, with some displaying potent activity against several multidrug-resistant bacteria.

Did you know that air pollution can impair our sense of smell and cause anosmia? Studies have shown that exposure to small airborne pollution particles, largely from the combustion of fuels in vehicles, power stations and our homes, can lead to olfactory dysfunction, causing a gradual erosion of our sense of smell over time. This can have significant effects on our overall wellbeing, from reducing our ability to taste and enjoy food, to potentially being an early warning sign of dementia. Researchers from Johns Hopkins School of Medicine and Karolinska Institute have found a strong correlation between higher pollution levels and poorer smelling ability, suggesting that we need to take air pollution more seriously to protect our health.

Teflon, a material that doesn't stick to anything, was stumbled upon accidentally in 1938 by a chemist named Roy Plunkett. Teflon's properties make it perfect for things that need to be slippery, chemical-resistant, or waterproof, which means it has a lot of applications. It can be found all over the place, from raincoats to industrial ball bearings to artificial joints. The incredible properties of PTFE, the chemical name for Teflon, come from its molecular structure. It's a polymer, meaning it's made of long chains of repeating units of atoms strung together. PTFE has tight carbon-fluorine bonds that ignore the normal, intermolecular forces that help substances stick to each other. Even the famously adhesive feet of geckos usually can't get a grip on it. Learning about the properties of materials like Teflon can inspire independent exploration of science and engineering, which can lead to exciting career opportunities in fields like materials science and chemical engineering.
