Low gravity in space travel found to weaken and disrupt normal rhythm in heart muscle cells

Johns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues and disrupted their normal rhythmic beats when compared to Earth-bound samples from the same source.

Those aren’t Dyson spheres, they’re HotDOGs

If there really are advanced alien civilizations out there, you’d think they’d be easy to find. A truly powerful alien race would stride like gods among the cosmos, creating star-sized or galaxy-sized feats of engineering. So rather than analyzing exoplanet spectra or listening for faint radio messages, why not look for the remnants of celestial […]

Perseverance rover spots unusual striped rock on Mars

Last week, team scientists and the internet alike were amazed when Perseverance spotted a black-and-white striped rock unlike any seen on Mars before. Is this a sign of exciting discoveries to come?

Study raises questions about validity of standard model of solar flares

Solar flares are extremely intense events that occur in the sun’s atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electrons that hurtle from the magnetic reconnection region in the corona to the chromosphere.

Earth is getting a tiny new mini-moon. It won’t be the first (or the last)

Earth is going to have its very own mini-moon from September 29 until November 25. The regular moon’s new, temporary friend is 2024 PT₅, an asteroid captured from the Arjuna asteroid group (called the “Arjunas”).

Quantized redshift and challenges to Big Bang hypothesis

A Doppler shift is defined as a change of frequency of light or sound when an object is moving toward or away from an observer. Edwin Hubble observed in 1929 that galaxies appear on average to be moving away from us (see figure above), which could indicate that the universe is expanding, an effect that […]

High-resolution images of the sun show how flares impact the solar atmosphere

Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as “space weather.” These events vary with the sun’s 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from extreme ultraviolet to X-rays) into space.

Advanced civilizations will overheat their planets within 1,000 years, researchers suggest

Earth’s average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or about 1.11°C (2°F) in total.

New physics needed? Experts suggest possibility of updating fundamental physics concepts

An unexpected finding about how our universe formed is again raising the question: do we need new physics? The answer could fundamentally change what physics students are taught in classes around the world.

Controlling light while measuring trapped ion qubits

Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements or resets on adjacent qubits in protocols like quantum error correction.

Physicists use quantum correlations of photon pairs to hide images from standard cameras

What if you could hide an image in plain sight—so well that even the most advanced cameras couldn’t detect it? Imagine encoding visual information using the properties of quantum optics, rendering it invisible to normal imaging technology.

Bizarre: Nikola Tesla Was Brought To Earth From Venus, Says Declassified FBI File

The letter mentions how Nikola Tesla successfully invented a device that could be used for Interplanetary Communication.

It explains that Tesla Engineers built the device after Tesla died, in 1950, and have been, since that time in close touch with ‘Space-Ships’.

Furthermore, the document from the FBI mentions how Tesla was a […]
