Phys.org / Nondestructive DNA sampling reveals 1,300 years of secrets in historic parchments
Researchers have demonstrated a nondestructive way to collect cellular material from historical parchment manuscripts, allowing them to conduct genetic analyses that offer new insights into everything from trade routes to ...
Phys.org / Chemists use sea sponge bacteria to create new molecules for drug discovery
Florida State University chemists have synthesized new molecules derived from bacteria found in a Pacific Ocean sea sponge, a breakthrough for the future of drug development, particularly for rare forms of cancer.
Phys.org / Q&A: What can plant evolution teach people about breeding better crops?
Today (May 22) is United Nations International Day for Biological Diversity, drawing attention to a critical resource for developing crops that are resilient or resistant to extreme weather and other threats to their health, ...
Phys.org / Behold the neuron, a complicated cell with a simple mission
Neurons, the uber-connected nerve cells that act as a main switchboard for the brain, are central to some incredibly complicated processes. They make it possible to think, walk, speak, and breathe. They even have built-in ...
Medical Xpress / Early birth safer for mother and baby in high blood pressure pregnancies, researchers find
Planned early birth for pregnant women with high blood pressure cuts maternal complications by nearly half and reduces the risk of stillbirth, without increasing the likelihood of cesarean section, according to data published ...
Phys.org / Sri Lanka teeth reveal rising plant diets thousands of years before agriculture
A new study published in Nature Ecology and Evolution examining human populations in Sri Lankan tropical rainforests shows that people's consumption of plants began increasing thousands of years before the introduction of ...
Phys.org / Mangrove loss threatens Sierra Leone's oyster harvesters
For 20 years, Millicent Turay has supported her family by collecting mangrove oysters near Sierra Leone's capital, Freetown, a common livelihood along the west African coast.
Medical Xpress / New AI tool may help personalize multiple myeloma treatment
An artificial intelligence-based tool may help physicians determine which newly diagnosed multiple myeloma patients are most likely to benefit from specific therapies, including immunotherapy and stem cell transplantation.
Phys.org / When Mendel's rules don't apply: Mouse study reveals hidden epigenetic inheritance
Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA code itself—can also be ...
Phys.org / Bioengineers condense protein engineering and testing to a single day
Proteins are critical to life—and to industry. There are countless proteins that could be engineered to treat and even cure serious diseases and cellular dysfunctions. Industrial applications are similarly promising, with ...
Medical Xpress / Sabiá virus has been circulating in Brazil for 142 years and mutating, study finds
The Sabiá virus causes an acute hemorrhagic and neurological syndrome. Four fatal cases have been recorded in the state of São Paulo since 1990. The virus has been circulating in Brazil for about 142 years. Genomic analyses ...
Phys.org / Listening to the rainforest: Researcher uses AI to monitor biodiversity through sound
In tropical forests, much of the biodiversity can be heard before it is seen. Birds call, insects buzz and frogs croak, creating complex soundscapes that reflect the presence of different species.
