How the Milky Way ‘ate’ smaller star clusters and galaxies

Credit: James Josephides and S5 Collaboration. Astronomers are one step closer to discovering the dark matter that envelops our Milky Way galaxy, thanks to a new map of twelve streams of stars orbiting our galactic halo. Understanding these stellar currents is very important for astronomers. In addition to discovering the dark matter that holds stars … Read more

Meeting ATS-recommended air quality standards would save thousands of lives – BIOENGINEER.ORG

January 13, 2022 – Paper published online in Annals of the American Thoracic Society is a study that discusses how new air quality standards recommended by the American Thoracic Society have the potential to prevent more disease and death than standards adopted by the U.S. Environmental Protection Agency (EPA). This study is part of the … Read more

New year, same universe | The Planetary Society

Curveball: Enceladus’ feathers may not come from the subterranean ocean. New research suggests that the famous feathers of Saturn’s moon (pictured) could instead come from pockets of melted water hidden in Enceladus ’ice shell. One of the scientists in this study, physicist Colin Meyer of Dartmouth University, said this research does not oppose the idea … Read more

First Nano-Sized Molecular Device Capable of Sensing and Altering Cells’ Bioelectric Fields

Conceptual drawing of a new molecular device. For experiments outside the human body (in vitro), the device would nest on the cell membrane: the reporter molecule would detect a local electric field when activated by red light; the attached molecule of the “modifier” would change that electric field when activated by blue light.

Can We Feed Billions of Ourselves Without Wrecking the Planet?

Can we feed billions of ourselves without destroying the planet? We are now producing more food more efficiently than ever, and for a human population of 7 billion there is much to visit. But it comes at a drastic cost in environmental degradation, and the boon doesn’t reach many people. Sustainable food production, a new … Read more

How to invent new candies for a living

Modern candy trays contain a seemingly endless variety of classic and limited flavor combinations that will entice your palate. With fans of a favorite concoction (chocolate and peanut butter! Biscuits and cream!), Candy companies are throwing out an offer off the wall with a clip that seems to be the result of a corporate rush … Read more

There’s a Hidden Mathematical ‘Law’ in The Sand Megaripples Found All Over Earth

Wherever there is sand and atmosphere, prevailing winds can whip the grains into wavy shapes, pleasing to the eye with their soothing repetition. Certain sand waves, with wavelengths between 30 centimeters (almost 12 inches) and a few meters (about 30 feet), are known as megaripples: they are the size between ordinary waves on the beach … Read more

Tiger shark migrations altered by climate change, new study finds – BIOENGINEER.ORG

A new study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science found that the locations and timing of tiger shark movements in the western North Atlantic have changed due to rising ocean temperatures. These climate changes later shifted the movement of sharks outside protected areas, leaving sharks … Read more
