La comunicación de las coníferas es compleja y puede verse alterada por la contaminación del aire

Conifers are dominant tree species in boreal forests, but they are susceptible to attack by bark beetles. A new study from the University of Eastern Finland shows that upon attack by bark-feeding weevils, conifers release substantial quantities of volatile organic compounds that provide important cu...

Naturaleza vs laboratorio: Las diferencias entre evolución experimental y adaptación natural

Humans have unwittingly been carrying out evolution experiments for millennia through the domestication of plants, animals, and fungi. Starting with the seminal experiments of William Dallinger in the late 19th century, such experiments have been performed under controlled laboratory conditions to b...

Un hongo que se encoge de tamaño para infectar mejor el cerebro

A fungus that is a common cause of fungal meningitis undergoes a remarkable transformation once it enters the body, allowing it to infect the brain, according to new research by scientists at University of Utah Health. Studies in mice show that as the fungal intruder travels through the body, it shr...

Un nuevo método para imprimir espejos de tamaño variable con una reflectividad superior al 99%

Dielectric mirrors, also referred to as Bragg mirrors, reflect light nearly completely. Hence, they are suited for various applications, such as camera systems and sensor systems for microscopy and medical technologies. So far, such mirrors have been produced by complex processes in expensive vacuum...
