Phys.org / Total synthesis of ibogaine creates new opportunities for studying a psychoactive plant derivative
Ibogaine—a psychoactive plant derivative—has attracted attention for its anti-addictive and anti-depressant properties. But ibogaine is a finite resource, extracted from plants native to Africa like the iboga shrub (Tabernanthe ...
Phys.org / Evidence of cannibalism by ancient Magdalenian people found in cave in Poland
A team of archaeologists, paleontologists, and historians from several institutions in Spain, Germany, and Poland, has found evidence of Magdalenian people from approximately 18,000 years ago, living in a cave in what is ...
Phys.org / Dutch space instrument SPEXone produces world map of aerosols
On February 8, 2024, NASA launched its PACE climate satellite with the Dutch aerosol instrument SPEXone onboard. A full year of observations now yields a world map of aerosols.
Phys.org / Computational tool maps cell differentiation with precision and efficiency
Understanding how cells transform into specialized types during human development is a central challenge in biology. This complex process, known as cell differentiation, holds the key to understanding developmental biology ...
Phys.org / Scratching through negative emotions: Exploring the mind-body connection in Japanese macaques
Research has shown that human bodily responses and cognitive shifts affect each other in both directions. We feel sorry because we cry, but also cry when feeling sorry. So, what then for our primate cousins? To date, their ...
Phys.org / Scientists elucidate molecular mechanisms behind dinoflagellate cyst dormancy
Dinoflagellates play crucial roles in aquatic ecosystems, particularly as major contributors to harmful algal blooms. They can enter a dormant stage, known as the resting cyst stage, that allows them to survive for extended ...
Phys.org / Optimized nickel particles improve catalyst performance for hydrogenation reactions
A research team led by Wang Guozhong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel method to precisely control the size of nickel (Ni) particles in catalysts, improving ...
Phys.org / Bacterial species study challenges assumption that structural similarity predicts protein behavior
A new study published in Biochemistry sheds light on how bacteria regulate their genes, challenging long-held assumptions about protein behavior. The research compares how two bacterial species—Escherichia coli and Mycobacterium ...
Phys.org / Fiber image transmission technology for minimally invasive endoscope developed
Optical fibers are fundamental components in modern science and technology due to their inherent advantages, providing an efficient and secure medium for applications such as internet communication and big data transmission. ...
Phys.org / 'Temperamental' stars may be distorting exoplanet observations
"Temperamental" stars that brighten and dim over a matter of hours or days may be distorting our view of thousands of distant planets, suggests a new study led by UCL researchers.
Phys.org / New AI model deciphers the code in proteins that tells them where to go
Proteins are the workhorses that keep our cells running, and there are many thousands of types of proteins in our cells, each performing a specialized function. Researchers have long known that the structure of a protein ...
Phys.org / Antarctic snow harbors microplastics: New technique uncovers hidden pollution
Scientists have discovered microplastics in the snow near some of Antarctica's deep field camps, revealing how far-reaching plastic pollution has become. While not new, it's the first time these tiny pieces of plastic have ...
