As the planet warms and polar ice melts, our global average sea level is rising. Although exact ocean heights vary due to local geography, climate over time, and dynamic fluid interactions with gravity and planetary rotation, scientists observe sea level trends by comparing measurements against a 20 year spatial and temporal mean reference.

This visualization uses the visual metaphor of a submerged porthole window to observe how far our oceans rose between 1993 and 2022.

The blue mark on the ruler shows the exact measurements of the Integrated Multi-Mission Ocean Altimeter Data for Climate Research. The level of the animated water changes more smoothly, driven by a 60-day floating average of the same data.

Scientists demonstrate terahertz wave camera can capture 3D images of microscopic world

Loughborough University scientists are the first to demonstrate that a terahertz wave camera can capture 3D images of microscopic items hidden inside small objects.

Lead researcher Dr. Luana Olivieri says though the research is in the early stages, the team's latest study could have "major implications for a range of fields with relevance in cancer screenings, security, and materials research."

Researcher 3D prints world's smallest wineglass with new method

Researchers have 3D-printed the world's smallest wine glass with a rim smaller than the width of a human hair. But the idea wasn't to cater to extremely light drinkers. Rather, the glass was printed to demonstrate a new simplified technique for creating silica glass structures for a range of applications from telecommunications to robotics.

Europe's Euclid space telescope to launch on July 1

The European Space Agency said on Wednesday its space telescope Euclid is scheduled to launch on July 1, blasting off on a mission to shed light on the mysteries of dark matter and dark energy.

The mission will launch on a SpaceX Falcon 9 rocket from Cape Canaveral in Florida, with the broadcast beginning at 1430 GMT, the ESA said in a tweet.

Neuralink will test its chip in in human trials this year says Elon Musk

Neuralink, the biotech venture led by Elon Musk, expects to begin its human trials later this year, the billionaire said in France last week. Musk did not reveal the details of the number of participants in the trial during his talk at the VivaTech event in Paris.

Launched in 2016, Neuralink is yet another moonshot project from Musk, where he wants to link the human brain to a computer. Musk's ideal application for the technology is to enable a paraplegic person to walk again. So far has only demonstrated the technology in monkeys who have been able to play video games.

Giant Paint-Eating Snails Spotted in Florida, Putting State Agriculture at Risk

Adult snails of this species can grow up to 20.3 centimeters (8 inches) and lay thousands of eggs at a time. Their shells have pointy edges that are sharp enough to puncture the tires of vehicles that run over them. They also pose a serious risk to humans because they carry a parasite that can cause meningitis.

The giant snail is among the most invasive species in the world; it eats plaster, paint, and stucco, and poses significant threats to vegetation.

World's first cosmic-ray GPS can detect underground movement

Cosmic rays are high-energy particles originating from outer space, including sources such as the sun, distant galaxies, supernovae, and other celestial bodies. Although we can't see or feel cosmic rays directly, they constantly bombard the Earth from outer space.

In fact, these particles are so abundant that scientists estimate one cosmic ray hits one square centimeter of the Earth's surface every minute! Scientists study cosmic rays to learn about the universe and how particles interact at high energies.

A team of scientists have successfully demonstrated the world's first cosmic-ray GPS to detect movement underground and in volcanoes which can potentially aid in future search-and-rescue missions.

Researchers discover that worms use electricity to jump

In nature, smaller animals often attach themselves to larger ones to "hitch a ride" and save energy migrating large distances. Researchers show how microscopic worms can use electric fields to "jump" across Petri plates or onto insects, allowing them to glide through the air and attach themselves, for example, onto naturally charged bumblebee chauffeurs.
