Humanity is the unlikely result of 4 billion years of evolution. From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves – evolution shaped us. Organisms reproduced imperfectly. Mistakes made when copying genes sometimes made them better fit to […]

How an organism can sense and cope with warming temperatures is key for survival, particularly under current global warming trends. The importance of this subject was recognized by 2021’s Nobel prize in Physiology & Medicine awarded to work on TRP channels, key mammalian peripheral heat sensors. Endotherms -such as mammals and birds – maintain their […]

Oumuamua may be hunk of nitrogen-rich planet The interstellar object Oumuamua is likely a piece of a planet rich in nitrogen that broke off about 500 million years ago and is shaped more like a cookie than a cigar. Researchers used computer models focusing on Oumuamua’s shape, size and shininess to determine the object’s possible […]

For a long time Alzheimer disease has been studied mostly as a neuronal disease. However, recently the role of the immune system is getting more attention and its involvement more clear. Recent research has shown that a subpopulation of T cells could be key to early Alzheimer’s detection. How were these T cells discovered? Firstly […]

Chemistry

Turning simple, individual molecules into complex, interconnected materials is the core of polymer chemistry. There is currently an increasing demand for materials with sophisticated properties such as self-healing and reusable adhesivity. However, achieving polymers with such functionalities generally demands higher structural complexity, synthetic difficulty, and cost. Now, a team of chemists has designed a supramolecular […]

Prolonged exposure to sunlight is not recommended. Even though is really important to synthesize vitamin D which helps us absorbing calcium or phosphate and maintain a mineralized skeleton, the effects of sun´s ultraviolet radiation (mainly UVA and UVB) can be prejudicial in the long term. Main issues may be sunburn (UVB), reduced skin elasticity leading […]
