Gravity can be a real downer when you are trying to grow organs. That’s why experiments in space are so valuable. They have revealed a new perspective into biological sciences, including insights into making human tissues. Gravity influences cellular behavior…
We are highly sensitive to people around us. As infants, we observe our parents and teachers, and from them we learn how to walk, talk, read — and use smartphones. There seems to be no limit to the complexity of…

In this illustration, a pulsar (PSR J0337-1715) is shown with two white dwarf companions. The green mesh illustrates the curvature of space-time caused by the different masses. (Size and distances of the three components are not to scale.) Once again,…
Think back to life before stay-at-home orders. Does it feel like just yesterday? Or does it seem like ages ago — like some distant era? Of course, time is precise. It takes 23.9 hours for the Earth to make one…
In this episode of Life’s Little Mysteries, we’ll take a closer look at the universe, which contains all elements, energy, matter and contents of space. Where did the universe come from, what’s it made of and will it ever stop…
The Murchison Widefield Array (MWA) — a network of radio telescopes in the Australian outback — is scouring the skies for traces of neutral hydrogen, the last surviving molecule of the cosmic dark ages. Update: This study, which had been…
The velocity-distribution data for gaseous rubidium atoms which confirmed the discovery of the Bose–Einstein condensate in 1995. Scientists have generated an exotic form of matter in the unique microgravity environment aboard the International Space Station and are using it to…
A lung x-ray from the patient before she received the transplant shows severe damage. In a first, a young COVID-19 patient in the U.S. has received a double-lung transplant after the coronavirus ravaged her lungs. The patient, a Hispanic woman…
The world’s largest atom smasher has “given birth” to a set of four ultraheavy particles — called top quarks. The formation of these chubby-but-tiny quadruplets, at the Large Hadron Collider in Geneva, Switzerland, has long been predicted by the Standard…
An artist’s impression of a fast radio burst (FRB) reaching Earth, with colors signifying different wavelengths. Astronomers have discovered an activity cycle in another fast radio burst, potentially unearthing a significant clue about these mysterious deep-space phenomena. Fast radio bursts,…
NASA recently launched the Commercial Lunar Payload Services (CLPS) initiative whose aim is to find the best future payloads to deliver to the surface of the moon. These payloads would include instruments for basic science investigations. Shown here, a Lockheed…
