The European mole, equipped with its formidable digging shovels, can effortlessly tunnel through the earth. The same holds true for the Australian marsupial mole. Despite residing in vastly different regions, the two species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Scientists want to use quantum mechanics to capture higher-resolution images of the night sky.

For the purposes of astronomy, the two beams are collected by two telescopes that are separated by some distance (called baseline interferometry). But despite its effectiveness, classic interferometry is subject to some limitations. Andrei Nomerotski, an astrophysicist with the BNL and a co-author on the paper, explained to Universe Today via email.

“Interferometry is a way to increase the effective aperture of telescopes and to improve the angular resolution or astrometric precision,” he said. “The main difficulty here is to maintain the stability of this optical path to very high precision, which should be much smaller than the photon wavelength, to preserve the photon’s phase. This limits the practical baselines to a few hundred meters.”

In recent years, scientists have investigated the possibility of using quantum principles to enable next-generation astronomy. The basic idea is that photons could be transferred between observatories without physical connections that are expensive to build and maintain. The key is to take advantage of quantum entanglement, a phenomenon where particles interact and share the same quantum state — despite being separated by considered distance.

TOKYO (AP) — A Japanese startup announced plans Tuesday to launch commercial space viewing balloon flights that it hopes will bring an otherwise astronomically expensive experience down to Earth.

Company CEO Keisuke Iwaya said passengers do not need to be billionaires, go through intense training or have the language skills needed to fly in a rocket.

“It’s safe, economical and gentle for people,” Iwaya told reporters. “The idea is to make space tourism for everyone.” He said he wants to “democratize space.”

ChatGPT is best known as an AI program capable of writing essays and answering questions, but now Microsoft is using the chatbot to control robots.

On Monday, the company’s researchers published (Opens in a new window) a paper on how ChatGPT can streamline the process of programming software commands to control various robots, such as mechanical arms and drones.

“We still rely heavily on hand-written code to control robots,” the researchers wrote. Microsoft’s approach, on the other hand, taps ChatGPT to write some of the computer code.

Can we objectively tell how fast we are aging? With a good measure, scientists might be able to change our rate of aging to live longer and healthier lives. Researchers know that some people age faster than others and have been trying to concisely measure the internal physiological changes that lead to deteriorating health with age.

For years, researchers have been using clinical factors normally collected at physicals, like hypertension, cholesterol and weight, as indicators to predict aging. The idea was that these measures could determine whether someone is a fast or slow ager at any point in their . But more recently, researchers have theorized that there are other biological markers that reflect aging at the molecular and cellular level. This includes modifications to a person’s genetic material itself, or epigenetics.

While each person has a that largely does not change over their lifetime, to their genetic material that occur throughout life can change which genes are turned on or off and lead to more rapid aging. These changes typically involve the addition of methyl groups to DNA and are influenced by social and environmental exposures, such as , smoking, pollution and depression.
