After 10 years of upgrades, this legendary telescope has returned to chase black holes, asteroids and cosmic chemistry‎

The Haystack 37m Telescope has been a landmark in radio astronomy and radar studies of the solar system since its first light in 1964. Over the following four decades, it supported NASA's Apollo landings on the moon, made planetary radar maps of the surface of Venus, contributed to experimental tests of Einstein's general relativity, supported the development of VLBI, and conducted foundational studies of quasars and star-forming regions.

What if the direction of a magnet could shape the building blocks of life?‎

In a new discovery, researchers from the Hebrew University of Jerusalem and the Weizmann Institute of Science have found that something in the direction of a magnetic field can influence how molecules of life behave at the most fundamental level and how early chemical processes linked to life may have unfolded.

Religion plays a greater role in the economy than previously thought, says paper‎

Religion plays a greater role in growth, prosperity and economic development than many people realize. This is the finding of a paper published by the Rockwool Foundation Berlin (RFBerlin) ahead of Pentecost, marking the founding of the Christian Church. "Religion influences key economic processes: saving and financial behavior, education, family size and the labor supply, openness to technology, social norms and political institutions," says RFBerlin project leader Sascha Becker.

An explanation for the massive black holes the JWST found in the early universe‎

One of the most puzzling findings from the JWST's observations of the early universe is the size of black holes. According to our understanding of black hole growth, these early black holes are far more massive than expected. Astronomers expected the unexpected from JWST, and it has delivered. Now the challenge is to update models of the universe to include these new observations.

Bees found an unlikely new food source, and it could reshape how a destructive forest disease travels‎

New research published in NeoBiota has found that the Western honey bee—an introduced species to Australia—and the devastating, invasive plant fungus known as myrtle rust (Austropuccinia psidii) may have formed a mutually beneficial relationship known as "invasional mutualism."

Portugal burial reveals first known bone dental bridge in national archaeological record‎

The first documented case of a fixed bone bridge unearthed in Portugal was presented in the International Journal of Osteoarchaeology by researchers Ms. Steffi Vassallo and her colleagues. The item is estimated to date to the 19th century and is likely to have served a more aesthetic than functional purpose.

Image: NASA's Psyche mission captures Mars' Huygens Crater‎

Captured by the multispectral imager instrument on NASA's Psyche mission, this is an enhanced-color view of the large double-ring crater Huygens (upper right; about 290 miles, or 470 kilometers, in diameter) and the surrounding heavily cratered southern highlands near 15 degrees south latitude. The various colors in this dramatic scene are likely due to differences in the compositional properties of dust, sand, and bedrock in this ancient terrain. The image scale is around 2,200 feet (670 meters) per pixel.

Lab fish cycles are hours out of sync with natural ones, researchers discover‎

When researchers moved medaka—a fish commonly used in experiments—out of the lab and into more natural conditions, their reproductive clock shifted by hours, suggesting that laboratory findings may not fully capture their natural reproductive timing.

Tiny sea creature Porpita porpita may live adrift at sea for years longer than previously thought‎

A new study of the blue button (Porpita porpita), a small and elusive sea creature which lives on the surface of the ocean, has found that it may live for several years adrift at sea, much longer than previously estimated.
