Medical Xpress / A step toward lab‑grown sperm: Scientists turn stem cells into early sperm cells in a mini‑testis
About 9% of men of reproductive age in the United States experience fertility problems. One of the many causes of male infertility is a failure in germline development, the process by which embryonic cells develop into sperm ...
Phys.org / Pump that recreates human heartbeat blood flow on lab chips inspired by an accordionist
For more than 25 years, lab-on-a-chip technology has allowed researchers to model human organs and blood vessels using real human cells in artificial microscopic environments. These microphysiological systems (MPS) may replicate ...
Phys.org / Disrupting single enzyme gene in herb red perilla produces green plants with enriched health-promoting molecules
Hiroshima University researchers have used genome editing to transform red perilla into a green look-alike and simultaneously restructured the plant's chemistry to boost levels of compounds prized for their potential health ...
Medical Xpress / Researchers find doctors played a critical role in the nation's opioid crisis
The official sum of opioid-related settlements between U.S. state and local governments and major pharmaceutical opioid manufacturers, marketers, distributors and retailers recently reached $58.58 billion. Stark statistics ...
Phys.org / A new record holder for the world's oldest amber discovered in China
Paleontologists in China have discovered the oldest chemically verified amber ever found, dating to 385 million years ago. That's approximately 140 million years before dinosaurs roamed Earth. The previous record holder was ...
Phys.org / Cellular transporter protein essential for nutrient absorption in pathogenic fungi may offer new treatment approaches
They are the cell's "gatekeepers": specialized proteins, known as transporters, selectively control which substances enter a cell and which do not. Researchers at the University of Münster and the National and Kapodistrian ...
Phys.org / Scientists create stable 'boron graphene' and uncover quantum liquid crystal state
Graphene has long been regarded as one of the most promising materials for future electronics, but its relatively weak electron interactions have limited its potential for applications such as high-temperature superconductivity. ...
Medical Xpress / AI disagreement may shake patient trust in doctors
Patient trust in medical professionals might hinge on what artificial intelligence (AI) has to say, according to a team led by Penn State researchers.
Phys.org / A volcano in the Philippines erupted 2 weeks ago: Why scientists are still watching it closely
Two weeks ago, the Philippine Institute of Volcanology and Seismology recorded three distinct, short-lived explosions in less than five minutes at Taal Volcano. The eruption sent a column of ash and steam up to 1.2 km (0.75 ...
Phys.org / Tiny gene edit cuts cadmium in rice by 48% without reducing yields
Cadmium (Cd) contamination poses a serious threat to global food safety. As a toxic and carcinogenic heavy metal, cadmium can accumulate in agricultural soils through industrialization and urbanization before entering the ...
Phys.org / Braided, exotic particles could build reliable, universal quantum computers
A truly useful quantum computer must be able to run any algorithm, with the same versatility an ordinary laptop offers. Physicists have now shown a new way to give a quantum computer exactly that flexibility, harnessing the ...
Medical Xpress / Roasted and browned: How gut bacteria break down heated foods
Crusty bread, fried meat and roasted coffee owe their characteristic taste and browning to chemical reactions that occur when foods are heated. In the so-called Maillard reaction, amino acids—the building blocks of proteins—react ...
