New Haven, Conn. — As rising global temperatures alter ecosystems worldwide, animal species usually have two choices: adapt to changing local conditions or flee to a cooler clime. Ecologists have long assumed that the world’s bird species were best equipped to respond to the pressures of climate change simply because they have the option of flying to higher altitudes or towards global poles. But a new Yale study finds that few bird species are able to escape the realities of a warming world. The findings were published May 28 in the journal Nature Ecology and Evolution. “They can’t move fast enough or far enough to ...

Nature categorizes particles into two fundamental types: fermions and bosons. While matter-building particles such as quarks and electrons belong to the fermion family, bosons typically serve as force carriers—examples include photons, which mediate electromagnetic interactions, and gluons, which govern nuclear forces. When two fermions are exchanged, the quantum wave function picks up a minus sign, i.e., mathematically speaking, a phase of pi. This is totally different for bosons: Their phase upon exchange is zero. This quantum statistical property has drastic consequences for the behaviour of ...

Mechanoluminescence (ML) is a type of luminescence that occurs when a material emits light in response to an external mechanical stimulus, such as scratching, pressing, or stretching. Unlike electroluminescence (EL) or photoluminescence (PL), ML does not require an electric energy or light excitation; instead, it directly converts mechanical energy into optical emission. Then, devices fabricated from ML materials are inherently passive. This characteristic represents an intelligent and energy-efficient light-emission mode. However, most current ML research mainly focuses on the study of single-matrix materials, whose stress-induced ...
