A study published Oct. 10 in Current Biology has now found that a type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin’s circadian clock to the light-dark cycle, independent of the eyes or brain. This means that skin can sense whether it is day or night even when it’s cultured by itself in a dish. Researchers now want to see if skin heals better if it’s exposed to certain types of light.
Organic chemists have figured out how to synthesize the most common molecule arrangement in medicine, a scientific discovery that could change the way a number of drugs – including one most commonly used to treat ovarian cancer – are produced. Their discovery, published today in the journal Chem, gives drug makers a crucial building block for creating medicines that, so far, are made with complex processes that result in a lot of waste.
A team of researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, has realized another landmark achievement with their breakthrough lithium-ion battery technology.

Since its invention during the Second World War for soldiers stationed in countries where malaria transmission rates were high, researchers have worked to pinpoint precisely how DEET actually affects mosquitos. Past studies have analyzed the chemical structure of the repellent, studied the response in easier insects to work with, such as fruit flies, and experimented with genetically engineered mosquito scent receptors grown inside frog eggs. However, the Anopheles mosquito’s neurological response to DEET and other repellents remained largely unknown because directly studying the scent-responsive neurons in the mosquito itself was technically challenging and labor-intensive work.

Chemists at Saint Louis University, in collaboration with scientists at the College of Charleston and the NSF/NASA Center for Chemical Evolution, found that deliquescent minerals, which dissolve in water they absorb from humid air, can assist the construction of proteins from simpler building blocks during cycles timed to mimic day and night on the early Earth.
Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role. Recently, the chemists Sebastian Mai and Leticia González from the Faculty of Chemistry of the University of Vienna succeeded in simulating the extremely fast spin flip processes that are triggered by the light absorption of metal complexes. The study is published in the journal "Chemical Science".
