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, ...
Medical Xpress / You can't hear it, yet this sound may explain paranormal experiences
Infrasound is very low-frequency sound, below 20 Hertz (Hz), which humans typically can't hear. It can come from natural sources like storms, or from anthropogenic sources like traffic. Some animals use it to communicate, ...
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 / Light-based scans reveal how cells can be stable yet adaptable
Our cells adjust to ever-changing conditions while preserving internal states necessary for survival, but exactly how they achieve both adaptability and stability remains unclear. For the first time, researchers have used ...
Medical Xpress / Minimally invasive procedure outperforms drugs for advanced atrial fibrillation
A minimally invasive heart procedure may be a better first-line treatment than medication for people living with advanced forms of atrial fibrillation, according to a major international clinical trial led by researchers ...
Medical Xpress / Bacteria-resistant coating on catheters reduces infection and need for antibiotics
A new study shares the results of a clinical trial into the use of a catheter coated with a bacteria-resistant material. The Camstent Coated Catheters feature a bacteria-resistant polymer coating developed by scientists at ...
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.
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, ...
Phys.org / More than two species? Scientists challenge taxonomy of two-toed sloths in Amazonia
A new study by scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has revealed significant cryptic diversity within two-toed sloths (Choloepus) in Amazonia, challenging the long-established ...
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 ...
Phys.org / Fragile no more, nickelates get an upgrade that changes how superconductivity endures
Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science ...
