What makes us unique? Different from most, yet similar to a few? What shapes our physical, behavioral, and even mental makeup? The answer lies in our genes.
Passed from parents to their offspring, genes contain the information that specifies physical and biological traits.
But that’s not all. Genes are also responsible for diseases. Faulty genes can cause all kinds of issues that can manifest as birth defects, chronic diseases, or developmental problems.
Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method. The new method is presented in the journal Chem.
“This is a step towards addressing a major roadblock to nuclear energy,” says chemist and senior author Sarbajit Banerjee of ETH Zürich and Texas A&M University. “Lithium-6 is a critical material for the renaissance of nuclear energy, and this method could represent a viable approach to isotope separation.”
The conventional method used to isolate lithium-6, called the COLEX process, involves liquid mercury and has been banned in the United States since 1963 due to pollution concerns.
Mitochondria are the powerhouses in our cells, producing the energy for all vital processes. Using cryo-electron tomography, researchers at the University of Basel, Switzerland, have now gained insight into the architecture of mitochondria at unprecedented resolution.
The results of the study are published in Science.
They discovered that the proteins responsible for energy generation assemble into large “supercomplexes,” which play a crucial role in providing the cell’s energy.
Researchers have discovered that Daphne pseudomezereum (commonly known as Onishibari) contains a substance inhibiting replication of human immunodeficiency virus (HIV). The plants were cultivated at the Medicinal Plant Garden of the Faculty of Pharmaceutical Sciences, Toho University. This finding is expected to lead to the discovery of drug seeds for novel drugs with superior anti-HIV activity.
A paper reporting this study was published in the journal Phytochemistry. The research group was led by Professor Wei Li from the Department of Pharmacognosy, Faculty of Pharmaceutical Sciences, Toho University, in collaboration with the Duke University Medical Center in the United States.
The Thymelaeaceae family consists of over 53 genera and 800 species distributed worldwide, except in polar and desert regions. These plants contain diterpenoids, which exhibit significant biological activities, including anticancer, anti-HIV, and analgesic effects.
Historically, No Tech Improvement Has Affected Human Jobs. It’s the people who were smart enough to understand the paradigm shift and develop new skills to be better productive.
Three arguments for taking progress toward artificial general intelligence, or A.G.I., more seriously — whether you’re an optimist or a pessimist.
A team of geologists at the Chinese Academy of Geological Sciences, the Institute of Space Sciences and the Shandong Institute of Geological Sciences, all in China, has found evidence in soil samples collected from the far side of the moon that bolsters a theory that the moon was once covered by an ocean of magma. In their study published in the journal Science, the group analyzed a moon soil sample returned to Earth by China’s Chang’e-6 mission.
In 2024, the China National Space Administration launched a spacecraft that carried a lander to the surface of the far side of the moon. The mission was the first to collect samples from the far side of the moon and return them to the Earth. For this new study, the research team obtained 2 grams of the soil for testing.
The researchers used multiple methods to determine its composition and then compared the results to those of analyses of soil samples from the near side of the moon.
A private lunar lander has captured the first high-definition sunset pictures from the moon.
Firefly Aerospace and NASA released the stunning photos Tuesday, taken before the Blue Ghost lander fell silent over the weekend. One shot included Venus in the distance.
Firefly’s Blue Ghost landed on the moon on March 2, the first private spacecraft to touch down upright and perform its entire mission. It kept taking pictures and collecting science data five hours into the lunar night before it died for lack of solar energy.
A research team at UNIST has identified the causes of oxygen generation in a novel cathode material called quasi-lithium and proposed a material design principle to address this issue.
Quasi-lithium materials theoretically enable batteries to store 30% to 70% more energy compared to existing technologies through high-voltage charging of over 4.5V. This advancement could allow electric vehicles to achieve a driving range of up to 1,000 km on a single charge. However, during the high-voltage charging process, oxygen trapped inside the material can oxidize and be released as gas, posing a significant explosion risk.
The research team, led by Professor Hyun-Wook Lee in the School of Energy and Chemical Engineering, discovered that oxygen oxidizes near 4.25V, causing partial structural deformation and gas release.
