Could we store samples of Earth’s endangered biodiversity on the Moon for long-term preservation? This is what a recent study published in BioScience hopes to address as a team of researchers led by the Smithsonian Institution proposes how the Moon’s permanently shadowed regions (PSRs) located at the lunar north and south poles could be ideal locations for establishing a lunar biorepository where endangered species can be cryopreserved. This study holds the potential to safeguard Earth’s biodiversity from extinction while improving future space exploration and possible terraforming of other worlds.

“Initially, a lunar biorepository would target the most at-risk species on Earth today, but our ultimate goal would be to cryopreserve most species on Earth,” said Dr. Mary Hagedorn, who is a research cryobiologist at the Smithsonian National Zoo and Conservation Biology Institute and lead author of the study. “We hope that by sharing our vision, our group can find additional partners to expand the conversation, discuss threats and opportunities and conduct the necessary research and testing to make this biorepository a reality.”

The reason lunar PSRs are of interest for this proposal is due to several craters being completely devoid of sunlight from the Moon’s small axial tilt (6.7 degrees versus Earth’s 23.5 degrees). The team postulates this presents ample opportunity for storing several groups, including pollinators, threatened and endangered animals, culturally important species, and primary producers, just to name a few.

TAIPEI, Taiwan — Chinese-American physicist Tsung-Dao Lee, who in 1957 became the second-youngest scientist to receive a Nobel Prize, died Sunday at his home in San Francisco at age 97, according to a Chinese university and a research center.

Lee, whose work advanced the understanding of particle physics, was one of the great masters in the field, according to a joint obituary released Monday by the Tsung-Dao Lee Institute at Shanghai Jiao Tong University and the Beijing-based China Center for Advanced Science and Technology.

Lee, a naturalized U.S. citizen since 1962, was also a professor emeritus at Columbia University in New York.

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.

Think and you’ll miss it: researchers at MIT claim to have successfully created analog synapses that are one million times faster than those in our human brains.

Just as digital processors need transistors, analog ones need programmable resistors. Once put into the right configuration, these resistors can be used to create a network of analog synapses and neurons, according to a press release.

These analog synapses aren’t just ultra-fast, they’re remarkably efficient, too. And that’s pretty important, because as digital neural networks grow more advanced and powerful, they require more and more energy, increasing their carbon footprint considerably.

Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a University of Michigan study.

The findings suggest that asteroids in the asteroid belt, a region of the solar system roughly between Jupiter and Mars that contains much of the system’s rocky asteroids, have subsurface ice, something that has been suspected since the 1980s, according to Aster Taylor, a U-M graduate student in astronomy and lead author of the study.

The study also shows a potential pathway for delivering ice into the near-Earth solar system, according to Taylor. How Earth got its water is a longstanding question.

Researchers at the University of Cologne have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing / publication in Nature Physics.

A team of experimental physicists led by the University of Cologne have shown that it is possible to create superconducting effects in special materials known for their unique edge-only electrical properties. This discovery provides a new way to explore advanced quantum states that could be crucial for developing stable and efficient quantum computers. Their study, titled ‘Induced superconducting correlations in a quantum anomalous Hall insulator’, has been published in Nature Physics.

Superconductivity is a phenomenon where electricity flows without resistance in certain materials. The quantum anomalous Hall effect is another phenomenon that also causes zero resistance, but with a twist: it is confined to the edges rather than spreading throughout. Theory predicts that a combination of superconductivity and the quantum anomalous Hall effect will give rise to topologically-protected particles called Majorana fermions that will potentially revolutionize future technologies such as quantum computers. Such a combination can be achieved by inducing superconductivity in the edge of a quantum anomalous Hall insulator that is already resistance-free. The resultant chiral Majorana edge state, which is a special type of Majorana fermions, is a key to realizing ‘flying qubits’ (or quantum bits) that are topologically protected.
