UC Santa Barbara

Scientists at Stanford University and University of California, Santa Barbara have put forward a particularly interesting soft robot design, showing off an inflatable machine that can change shape and roll in controllable directions while untethered.

Phages, viruses that thrive by infecting bacteria, have long been mooted as a potential replacement for antibiotics, but they pose risks due to their own rapid evolution. New research suggests it may be possible to mitigate their risks.

Utilizing a new technique, ordinary wall-penetrating Wi-Fi signals could reportedly now be used to identify a person within a house.

Carbon dioxide in the atmosphere is a major driver of shifts in the Earth’s climate, and in the past too little CO2 has been associated with triggering ice ages. Now a team of scientists has found a surprising new mechanism that could lead to ice ages: Tropical tectonic activity.

​In what may be seen as a worrying development to those troubled by the growth of the surveillance state, researchers at the University of California have demonstrated that they can count people through walls using only Wi-Fi signals.

American scientists have developed a smartphone app that can identify types of bacteria in one hour, down from a typical turnaround of 18 to 28 hours. The reduced detection time should mean faster diagnosis, treatment and recovery for patients, as well as reduced costs.

Animals regularly cast off bits of their DNA into aquatic environments. Known as environmental DNA (eDNA), it can be detected in water samples, letting scientists know if a species is present in the region. Soon, it could be used to warn beachgoers of nearby great white sharks.
