When it comes to longevity in the animal kingdom, the Naked mole-rat is often touted as one of the longest living animals known to man, and some say that they functionally do not age, only ever dying of disease or predation. In this article we will investigate these claims, and discover what exactly is so exciting about these aesthetically challenged rodents which has made so many researchers so optimistic about the future of human longevity.

Are Naked Mole-Rats Immortal?

Let’s dispel one of the largest misconceptions about naked mole-rats (Heterocephalus glaber) before we dive into what makes these rodents so interesting. No, naked mole-rats are not immortal in any sense of the word. First documented in 1,842 by German naturalist Eduard Rüppell, we have formally studied this species of rodent for over 180 years, and we have yet to see any immortal naked-mole rats running around, in the wild or otherwise. Neither have we seen a naked mole-rat coming close to the longevity enjoyed by our own species, let alone the longevity enjoyed by other longer lived species such as the giant tortoise. However, it is not the lifespan itself that is so remarkable about the naked mole-rat, but rather its relative longevity compared to other rodents that makes the naked mole-rat so interesting.

Scientists are increasingly studying quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states of the others. The systems are correlated, even when they are separated by a large distance. The significant potential for applications in encryption, communications and quantum computing spurs research. The difficulty is that when the systems interact with their surroundings, they almost immediately become disentangled.

In the latest study by the Laboratory for Coherent Manipulation of Atoms and Light (LMCAL) at the University of São Paulo’s Physics Institute (IF-USP) in Brazil, the researchers succeeded in developing a light source that produced two entangled light beams. Their work is published in Physical Review Letters.

“This light source was an optical parametric oscillator, or OPO, which is typically made up of a non-linear optical response crystal between two mirrors forming an optical cavity. When a bright green beam shines on the apparatus, the crystal-mirror dynamics produces two light beams with quantum correlations,” said physicist Hans Marin Florez, last author of the article.

For the first time, a new study has identified enlarged perivascular spaces in the brains of migraine sufferers. Results of the study were presented recently at the annual meeting of the Radiological Society of North America (RSNA).

“In people with chronic migraine and episodic migraine without aura, there are significant changes in the perivascular spaces of a brain region called the centrum semiovale,” said study co-author Wilson Xu, an M.D. candidate at Keck School of Medicine of the University of Southern California in Los Angeles. “These changes have never been reported before.”

Migraine is a common, often debilitating condition, involving a severe recurring headache. Migraines may also cause nausea, weakness, and light sensitivity. According to the American Migraine Foundation, over 37 million people in the U.S. are affected by migraine, and up to 148 million people worldwide suffer from chronic migraine.

Now that it is passing through the Kuiper Belt, away from the light pollution of the inner Solar System, it has another lucrative mission: measuring the brightness of the Universe. These measurements will allow astronomers to make more accurate estimates of how many galaxies there are, which is still the subject of debate. According to new measures by New Horizons, the light coming from stars beyond the Milky Way is two to three times brighter than the light from known populations of galaxies — meaning that there are even more out there than we thought!

What’s new — The study was led by a team from the Center for Detectors (CfD), an academic research group at the Rochester Institute of Technology (RIT). They were joined by researchers from NASA’s Jet Propulsion Laboratory, the Space Exploration Sector (SES) at the Johns Hopkins University Applied Physics Laboratory (JHUAPL), the University of California Irvine, and the Space Sciences Laboratory (SSL) at UC Berkeley. The paper that describes their findings recently appeared online and has been accepted for publication in The Astrophysical Journal.

The proteins can record histories of cellular events.

Researchers from MIT developed a technique to induce cells to record the history of cellular events in a long protein chain that can be imaged using a light microscope. The technique could help understand the critical steps involved in the processes, such as memory formation, response to drug treatment, and gene expression.

Studying the molecular processes within cells can provide important insights into their function and how they contribute to the overall functioning of an organ.

Forged 66 million years ago, an enormous impact crater near Chixculub, Mexico, was left undiscovered until only a few short decades ago. But what caused it?

Millions of years ago, a dramatic mass extinction wiped out the dinosaurs.
