Researchers have found adding a hyperactive form of the protein Rac2 to macrophages, immune cells that eat pathogens, causes them to cannibalize T cells. The novel technique could potentially boost the effectiveness of an emerging cancer treatment.

Using a temperature-driven "wax motor," researchers have created an adaptive roof tile system that helps keep a room at a comfortable 18 °C (65 °F). It delivers an extraordinary 3.1X reduction in cooling energy consumption, and 2.6X for heating.

Modified viruses have proven a handy way to get CRISPR/Cas9 gene editing materials into the nucleus of cells – but they're expensive, difficult to scale and potentially toxic. Now, researchers have found a non-viral approach that does the job better.

Scientists have identified two molecules that could help treat leukemia, in a way that’s far less damaging to healthy cells than existing chemotherapy. The compounds work using a different mechanism that’s more selective for cancerous cells.

If you say “jump” I say “how high?” – and a new robot from UC Santa Barbara says “over 100 ft.” The researchers say that’s higher than anything else has ever jumped, be it robot or animal, thanks to a unique design that multiplies its stored energy.

US researchers have developed an innovative smartphone-based kit that can test saliva samples for the presence of SARS-CoV-2 and influenza viruses. Early studies have found the cheap system is as accurate as current lab-based testing and much faster.

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.
