According to the researchers from the University of Pennsylvania, some of the amino acids found in the asteroid Bennu likely formed in a different way than was previously thought, effectively challenging what we thought we knew about the origins of life.

A complex web of interrelated factors make Earth a life-supporting planet, and some of those factors are chemical. New research shows how oxygen abundance regulates the availability of the important chemicals phosphorous and nitrogen on planets, and that few planets get it right. While discouraging, it could help us optimize our search for habitable worlds.

A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, a riddle that has persisted in nuclear physics for decades

In this week’s news-and-snark piece, Bill Maher offers a piece that may be controversial, for it’s about how men need to be “men” again.  He avers that the loss of masculinity in males is one reason why women are disappointed in men, and why people are having less sex.  The data are eye-opening; for example, 44% of Gen Z men say they’ve had no relationship experience at all during their teen years.  That means up to age 20! And you might be interested in the new genre of literature he describes: “romantasy”, in which women get involved with animals or half-animals like centaurs.

His solution? Men should “man up”. His example: Taylor Swift being engaged to football star Travis Kelce (“old-school wood”) after writing songs about all the lame men she was once involved with. (He describes songs by other women.) Is he right?  I have no idea.

The Moon has a busy next two weeks ahead of it. Fresh off of Tuesday’s annular solar eclipse, the Moon begins an evening tour of the planets in the last half of February 2026. The waxing Moon actually slides by every planet except Mars over the next week. As a highlight, the waxing crescent Moon actually occults the planet Mercury in a rare celestial event on the night of Wednesday, February 18th.

The psychedelic DMT has been linked to improved mental health outcomes before, but now, scientists have shown it reduces depression symptoms more than a placebo when given alongside therapeutic support

The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time

Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and show millisecond scale coherence, bringing robust quantum computers closer to reality.

Dark energy is one of those cosmological features that we are still learning about. While we can’t see it directly, we can most famously observe its effects on the universe - primarily how it is causing the expansion of the universe to speed up. But recently, physicists have begun to question even that narrative, pointing to results that show the expansion isn’t happening at the same rate our math would have predicted. In essence, dark energy might be changing over time, and that would have a huge impact on the universe’s expansion and cosmological physics in general. A new paper available in pre-print on arXiv from Dr. Slava Turyshev, who is also famously the most vocal advocate of the Solar Gravitational Lens mission, explores an alternative possibility that our data is actually just messy from inaccuracies in how we measure particular cosmological features - like supernovae.

Biologists have debated the reason why Homo sapiens evolved a prominent lower jaw, but this unique feature may actually be a by-product of other traits shaped by natural selection

For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron behavior. Using advanced imaging and spectroscopy techniques, they separated the signals from chains aligned in different directions to reveal their true nature. The findings suggest that squeezing the chains closer together could trigger a dramatic shift from semiconductor to metal. That means simply adjusting density could unlock entirely new electronic states.

We are used to heat flowing from hot objects to cool ones, and never the other way round, but now researchers have found it is possible to pull off this trick in the strange realm of quantum mechanics

Claiming that an inflammatory response to injury is inherently therapeutic is a massive leap of faith.

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after reaching its maximum size in about 11 billion years, it could begin collapsing, ultimately ending in a “big crunch” roughly 20 billion years from now.

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark energy. Columnist Leah Crane explores what observations tell us about how much universe is out there and whether it’s shaped like a sheet, a saddle or something else entirely

The smell of rotten eggs has solved one of exoplanet science's most persistent mysteries. Astronomers using the James Webb Space Telescope have detected hydrogen sulfide gas in the atmospheres of four massive Jupiter like planets orbiting the star HR 8799, marking the first time this molecule has been identified beyond our Solar System. The discovery settles a long standing debate about whether these enormous worlds are truly planets or failed stars called brown dwarfs because the sulfur had to come from solid matter accreted during planet formation, not gas!
