These scientists want to safeguard Earth’s species by cryogenically preserving them on the moon
A group of scientists has devised a plan to safeguard Earth’s species in a cryogenic biorepository on the moon.
Intended to save species in the event of a disaster on Earth, the plan makes use of craters that are permanently in shadow and therefore cold enough to allow cryogenic preservation of biological material without using electricity or liquid nitrogen, according to research from a group led by scientists at the Smithsonian, published last week.
The paper, published in the journal BioScience, draws on the successful cryopreservation of skin samples from a fish, and outlines a method for creating a biorepository that would keep samples of other species safe.
Combining Ayahuasca Compound with Drugs like Ozempic Could Help Treat Diabetes, Mouse Model Suggests
Researchers combined the drug harmine with a medication similar to Ozempic to boost the number and function of human insulin-producing cells transplanted into mice.
New Study Sheds Light on Dispersion of Languages, Ancient DNA
The new groundbreaking Language Velocity Field (LVF) method is helping researchers trace dispersion patterns of languages, including Greek, across the world.
The spatial evolution of languages can help deepen our understanding of people diffusion and cultural spread. The language velocity field estimation is different from the frequently used phylogeographic approach which cannot fully explain the language evolution induced by the horizontal contact among languages, such as borrowing and areal diffusion.
The study of language evolution, particularly its spatial dispersion, offers valuable insights into our collective past. Traditional approaches, such as the phylogeographic approach, often miss the complexity of language evolution.
Cutting-Edge Quantum Sensor Unveils the Hidden Atomic World
A new quantum sensor developed by researchers from Korea and Germany can measure magnetic fields at the atomic scale with high precision. This technology uses a single molecule for detection, offering superior resolution and the potential for significant advancements in quantum materials and molecular systems analysis.
In a scientific breakthrough, an international research team from Korea’s IBS Center for Quantum Nanoscience (QNS) and Germany’s Forschungszentrum Jülich developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.

Revolutionary DNA Nanotech Boosts Mass Cytometry by 500-Fold
ACE, a groundbreaking DNA-powered signal amplification technology, significantly enhances the sensitivity of mass cytometry, providing new insights into various biological and pathological processes.
Since the 1950s, researchers have employed “flow cytometry,” a renowned technique devised by Wallace Coulter, to characterize various types of immune cells in research studies and human blood samples. This method has significantly enhanced our understanding of immune cell development and provided innovative approaches for evaluating human health and diagnosing various blood cancers. Eventually, flow cytometry was extended to analyze other cell types as well.
In traditional flow cytometry, cell surface and intracellular proteins are detected with antibody molecules that are linked to fluorescent probes. However, while providing single-cell sensitivity, this method is limited in detecting multiple proteins by the number of fluorophores that can be clearly distinguished within the entire spectrum of fluorescent light.
