RMS Titanic: Solar flare may have contributed to sinking, study says

The RMS Titanic may have only taken the exact fatal course that saw it pierced and sunk by an iceberg on April 15, 1912 because a solar flare threw away the ship’s compass readings, a study proposed. According to a US meteorologist, the last night of the ocean liner sailing in the Atlantic was illuminated by the Northern Lights, the …

The dust may have controlled ancient human civilization

The map shows the Levant region (shaded in orange), which is the western part of the entire Fertile Crescent region (shaded in yellow); the study areas in Israel and Crete are in dashed gray boxes. The arrows of the Sahara and Negev deserts show the transport patterns of the dust and their thickness indicates the relative size of the grains …

Because blue is one of the brightest colors we find in nature

From bird feathers to fruit peels, the natural world has two main ways of visualizing color: through pigmented substances that provide selective color absorption, or through structural color – the use of microscopic structures to control the reflection of light. . Now scientists have devised a computer model that explains why the brightest opaque structural colors in nature are almost …

Theoretically, two layers are better than one for solar cell efficiency

Diagram of a double thin film solar cell. The sun enters from above and reaches the CIGS and CZTSSe layers which absorb light and create positive and negative particles that travel to the upper and lower contact layers, producing electricity.

Finding in 100-million-year-old amber reveals sexual intercourse of ostracods

Ostracods studied from Myanmar amber. Credit: NIGPAS Small bivalve crustacean ostracods are the most abundant fossil arthropods from the Ordovician and play an important role in paleoenvironmental reconstruction and evolutionary biology. The vast majority of fossilized ostracods are calcified shells, and their soft parts, which can provide valuable insight into the autoecology of ancient ostracods, are extremely rare. Recently, Dr. …

The first commercial airlock will head for the International Space Station later this year

By the end of the year, SpaceX’s Falcon 9 rocket will take off from central Florida, carrying a large metal cup meant to be attached to the outside of the International Space Station. The hardware is a one-of-a-kind commercial airlock, designed to carry payloads and other materials from inside the pressurized space station into the vacuum of space. The airlock …

Venus, once heralded as Earth’s twin, is a greenhouse (and a tempting target in the pursuit of life)

As Earth’s sister planet, Venus has endured a love-hate relationship when it comes to exploration. Now, new results suggest the presence of a potential habitability on Venusand the long-forgotten brother may find himself in the spotlight again. With its orbit close to the rising or setting sun, Venus shone clearly to early ancient astronomers. As humanity began exploring the solar …

A solar forecast with good news for civilization as we know it

The sun is starting to revive again. An international group of scientists announced Tuesday that the sun has emerged from the quieter end of its 11-year sunspot cycle and has now entered its 25th numbered cycle. (The numbering of sunspot cycles dates back to 1755.) The researchers predicted that the next cycle would be rather quiet. Solar scientists follow the …
