Phys.org / DNA molecular computer combines memory and computing at scales below 2 nm
Until now, molecular-level DNA circuits have mainly been used for simple tasks, such as detecting the presence of cancer-related substances. However, these systems have faced a key limitation: once a reaction occurs, the ...
Phys.org / New self-assembling polymers proven to be effective at gene delivery
A collaboration of scientists at the University of Manchester and the University of Birmingham has explored a more effective and less toxic way of delivering genetic material into cells, a challenge central to areas such ...
Phys.org / Brazil's farm expansion has left a vast soil carbon debt—but one fix could help meet climate goals
The conversion of Brazil's native biomes into agricultural areas has resulted in an estimated loss of 1.4 billion tons of soil carbon. This amount is equal to the emission of 5.2 billion tons of carbon dioxide (CO₂) equivalent, ...
Phys.org / CRISPR untangles five-gene protein that helps plants grow in early stages
For most of their lives, plants get their energy from photosynthesis. But during the seed to seedling stage, when they can't absorb light just yet, they rely on other sources, like fatty acids. To process the fatty acids, ...
Phys.org / How bacteria circumvent plants' immune system
How are bacterial pathogens able to effectively overcome plants' defense mechanisms? Researchers working with Professor Şuayb Üstün at Ruhr University Bochum, Germany, have found a surprising answer to this question: The ...
Tech Xplore / Video: Electrical control of a metal-mediated DNA memory
DNA stores our genetic code. What if it could also be integrated with electronics to store and read other information? Scientists have been investigating how to store data in DNA, but retrieving the information remains a ...
Science X / A giant bud is about to unleash one of nature's foulest, fastest, and most elusive spectacles in London
The rare and infamous titan arum (Amorphophallus titanum) may be just days away from opening inside of the Princess of Wales Conservatory, Kew Gardens' horticulturists have said. Known to many as the "corpse flower" due to ...
Medical Xpress / One delayed newborn shot can set off a costly chain reaction with lifelong consequences for children
Delaying hepatitis B vaccination after birth increases infections among newborns and decreases their survival rates and quality of life, according to a new Cornell University study. The longer the delay, the study found, ...
Tech Xplore / You probably wouldn't notice if an AI chatbot slipped ads into its responses
Hundreds of millions of people consult artificial intelligence chatbots on a daily basis for everything from product recommendations to romance, making them a tempting audience to target with potentially below-the-radar advertising. ...
Medical Xpress / An unexpected limit to SARS-CoV-2's immune defenses reveal a hidden virus trade-off
A new study has revealed that while SARS-CoV-2 can weaken part of the body's early immune response, it may also unintentionally trigger another defense that helps cells fight back. A new collaborative study has revealed a ...
Science X / A freezing mountain refuge reshapes early human survival, hinting at an unseen advantage
Archaeologists have identified the earliest sustained human occupation in Highland Southern Africa, and suggest it could not have existed without considerable collaboration at a time when we were becoming humans.
Phys.org / Rare two-colored lobster caught by fishermen off Cape Cod donated to aquarium
It might be a divided lobster, but it has united New Englanders in fascination.
