You may have experienced some signs you’re in love. Can’t get someone out of your head? Daydreaming about them when you should be working? Imagining your futures together? These dizzying thoughts are just a few of the telltale signs you’re in love.

Scientists have discovered more about why space travel makes astronauts anaemic when they return to Earth. Canadian researchers say 50% more red blood cells are destroyed in space and this continues for however long the mission lasts. As a result, long voyages to the Moon, Mars and beyond may be a challenge, they say. But their insights could benefit bedridden patients on Earth with the same condition.

A research effort led by Stanford scientists set the first Guinness World Record for the fastest DNA sequencing technique, which was used to sequence a human genome in just 5 hours and 2 minutes.

Space anemia is tied to being in the void and can stick around awhile.

As the James Webb Space Telescope begins the lengthy process of aligning its 18 primary mirror segments, a question burns in the astronomical community: What will the huge observatory look at first?

Researchers published a study proving that SARS-CoV-2 infects human adipose or fat tissue to multiply and elicit an inflammatory response corresponding with severe COVID-19.

Previous research has shown triclosan’s toxicity, but the new study provides a closer look at the changes caused in the gut’s microscopic population. Researchers connected specific gut microbial enzymes, notably gut microbial beta-glucuronidase (GUS) proteins, with triclosan and showed these enzymes drive triclosan to wreak havoc in the gut.

Magic Leap announced Tuesday that it was giving four healthcare partners early access to its next-gen augmented reality headset, including neurotechnology company SyncThink. With the new partnership, the company is interested in targeting vestibular disorders, which cause dizziness, SyncThink chief clinical officer Scott Anderson told The Verge.

We have grown up having two biological parents. That’s how we know science works. However, things are likely to change in the future, and we will soon have our minds blown. The prospects of gene-editing technology will likely make it possible for the next generations to have more than two biological parents.

Katherine Calvin was appointed NASA's new Chief Scientist and Senior Climate Advisor on Monday. She wants to improve data accessibility.

Scientists have found many planets orbiting distant stars, but so far no proof that any have moons. Now, researchers have detected signs of a large exomoon orbiting a Jupiter-like world.

Deep-sea biologists were stunned to find the largest known fish breeding ground, a discovery made last year near Antarctica. Details of the incredible find were published today, with researchers describing a sprawling colony of millions of icefish on seafloor of the Southern Ocean.

The experimental fusion reactor could help to unlock near limitless clean energy.

‘Seeing one in real life is indescribable,’ says marine biologist of the technicolour marine mollusc she spotted off Queensland

Here’s a brain teaser for you: scientists are suggesting spacetime may be made out of individual “spacetime pixels,” instead of being smooth and continuous like it seems. Rana Adhikari, a professor of physics at Caltech, suggested in a new press blurb that these pixels would be “so small that if you were to enlarge things so that it becomes the size of a grain of sand, then atoms would be as large as galaxies.”

Coronavirus loses 90% of its ability to infect us within 20 minutes of becoming airborne – with most of the loss occurring within the first five minutes, the world’s first simulations of how the virus survives in exhaled air suggest. The findings re-emphasise the importance of short-range Covid transmission, with physical distancing and mask-wearing likely to be the most effective means of preventing infection. Ventilation, though still worthwhile, is likely to have a lesser impact.

A distant exoplanet looks more like a football than the usual sphere, researchers report in a groundbreaking new study. The strange shape of ultrahot WASP-103b, which is more than 1,000 light-years from Earth, is due to the planet being stretched by the gravitational forces of its parent star, according to the new research.

The Xenobots can self-heal, and they reproduce in an entirely different way—Xenobots build other Xenobots.

It is thought that the water in the Moon’s soil came from hydrogen sent over by solar winds

In a historic procedure surgeons in the US have, for the first time, transplanted a genetically modified pig heart into a living human. The patient is currently still alive, has not rejected the pig organ and is being carefully monitored at the University of Maryland Medical Center.
