Robotic metamaterial: An endless domino effect      (via sciencedaily.com)     Original source 

If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.

The heat index -- how hot it really feels -- is rising faster than temperature      (via sciencedaily.com)     Original source 

Researchers showed in 2022 that heat index calculations by NOAA based on analyses from the 1970s don't adequately reflect the heat stress humans feel during the extremes of heat and humidity accompanying climate change. Using their revised heat index, the researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days.

Toxic metal particles can be present in cannabis vapes even before the first use, study finds      (via sciencedaily.com)     Original source 

Though vapes have been heralded as a 'safer' way to consume either nicotine or cannabis, they present their own suite of risks that are being revealed through increasing regulation. Now, scientists have discovered that nano-sized toxic metal particles can be present in cannabis vaping liquids even before any heating occurs, and the effect is worse in illicit products.

Tropical birds could tolerate warming better than expected, study suggests      (via sciencedaily.com)     Original source 

We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.
