Phys.org / From light to logic: First complete logic gate achieved in soft material using light alone
Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of visible light. The ...
Phys.org / Extinct rocket frog species identified from single 62-year-old museum specimen
Anyone walking through the Tarumã neighborhood in Curitiba (the capital of the state of Paraná, Brazil) today may find it difficult to imagine the area as it was in the past. Between the buildings, racetrack, and the city's ...
Phys.org / Multicellular cyanobacteria switch gene activity between day and night cycles
Cyanobacteria, also known as blue-green algae, occur worldwide in many varieties, including in single-cell form and in chains called filaments. While these tiny life forms can strongly influence many ecosystems, the details ...
Phys.org / Smart toilets in Cambodia fall short due to improper use
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was ...
Phys.org / Scientists map the hidden cellular 'postal codes' that shape every human face
Why do no two human faces look quite the same? Although we all follow the same biological blueprint, our features—the curve of a lip, the angle of a nose, the breadth of a jaw—diverge in endlessly subtle ways.
Phys.org / Humans bring gender bias to their interactions with AI, finds study
Humans bring gender biases to their interactions with Artificial Intelligence (AI), according to new research from Trinity College Dublin and Ludwig-Maximilians Universität (LMU) Munich.
Phys.org / Subverting plasmids to combat antibiotic resistance
Researchers in the Blavatnik Institute at Harvard Medical School have opened a new window into understanding the development of antibiotic resistance in bacteria.
Phys.org / Could the solution to the carbon problem be carbon itself?
Can we use carbon to help decarbonize the world and transform the energy and chemical industries? Yes, it seems, but there are some key challenges to overcome first.
Phys.org / Metal-phase protection enables durable acidic CO₂ electroreduction to formic acid
The electroreduction of carbon dioxide (CO2) into valuable chemicals and fuels typically operates under alkaline or neutral conditions, but the carbonation side reaction causes carbon loss. In addition, the main product is ...
Phys.org / Scientists get a first look at the innermost region of a white dwarf system
Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star is a type of white dwarf that exerts a powerful magnetic field as it pulls material from the larger ...
Phys.org / Isotope-based method can detect unknown selenium compounds
Although present in very small amounts, selenium (Se)-based compounds play important roles in protecting the body from oxidative stress, regulating thyroid hormones, strengthening the immune system, and even detoxifying heavy ...
Phys.org / AI traces prehistoric trade routes of Europe's prized 'green gemstone' trade
A multidisciplinary team of Spanish and Portuguese archaeologists and artificial intelligence experts has combined non-destructive archaeological measurement techniques, machine learning and explainable artificial intelligence ...
