Over time, clumps of dark matter began to gravitationally pull in regular matter, forming recognizable structures, such as galaxies. Galaxies, in turn, coalesced together into massive galaxy clusters that are linked across huge stretches of space by filaments of dark matter, creating what is now known as the cosmic web.

For years, scientists have speculated that magnetic fields within the cosmic web would help to produce shocks that might glow dimly in radio light. Now, for the first time, astronomers have captured this “predicted emission from the formation and growth of the large-scale structure of the Universe,” according to a recent study in Science Advances.

As COVID has demonstrated, when pathogens are moving through the population, we adjust, limiting interactions, even isolating, and generally changing the way we associate with one other. Humans are not alone. New research from Harvard scientists provides some insight into how pathogens change animal social behaviors.

“Extreme environmental conditions have a very strong influence on all animals,” said Yun Zhang, a professor in the Department of Organismic and Evolutionary Biology. But while this behavior has been seen in animals from simple fruit flies all the way up to primates, researchers have not understood what happens inside an individual animal’s brain that leads to infection-induced changes in social behavior.

In their new paper, published in Nature, Zhang and colleagues studied the small roundworm C. elegans, which exists in nature with two sexes: hermaphrodites that produce both eggs and sperm, and males. Under normal conditions, the hermaphrodites are loners, preferring to self-reproduce over mating with males. However, Zhang’s team found that the hermaphrodite worms infected by a pathogenic strain of the bacterium Pseudomonas aeruginosa became more interested in one another and increased their mating with males.

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between ‘then’ and ‘now’.

Down at the quantum scale of buzzing electrons, however, ‘then’ can’t always be anticipated. Worse still, ‘now’ often blurs into a haze of vagueness. A stopwatch simply isn’t going to work for some scenarios.

A potential solution could be found in the very shape of the quantum fog itself, according to a 2022 study by researchers from Uppsala University in Sweden.

A strange blob has been seen rapidly circling our galaxy’s central black hole. Now, astronomers have identified it as the exploded debris from two merging stars.

By studying this cosmic dawn, Mobasher hopes to answer fundamental questions about our universe today. Understanding the dark ages “would help us understand how galaxies are formed, how stars are formed, the evolution of galaxies through the universe,” he says. “How our own galaxy started, how it was formed, how fast it built up stars … all those questions are important questions we need to answer.”

Summary: Study reveals how the brain juggles morally conflicting outcomes while learning, finding people who opt to make decisions for personal gain at the expense of others can comprehend and empathize with potential negative outcomes, but still ultimately choose to pursue options that benefit them.

New research from the Netherlands Institute for Neuroscience sheds light on how the brain juggles morally conflicting outcomes during learning.

Space officials are wondering: Should the moon have its own time zone? The ESA has proposed the at a recent agency meeting held in the Netherlands.

Protons may have more “charm” than we thought, new research suggests.

A proton is one of the subatomic particles that make up the nucleus of an atom. As small as protons are, they are composed of even tinier elementary particles known as quarks, which come in a variety of “flavors,” or types: up, down, strange, charm, bottom, and top.

Typically, a proton is thought to be made of two up quarks and one down quark. But a new study finds it’s more complicated than that.

Biophysical Therapeutics, a drug discovery platform company that leverages computational biology, has emerged from stealth. The primary targets of the Delaware-based company are cancer, the diseases of aging (including Alzheimer’s disease) and – excitingly – aging itself.

Founded by Dr Michael Forrest, a Cambridge University biochemistry graduate with a PhD in computer science, Biophysical Therapeutics boasts renowned biotech entrepreneur Professor George Church (of Harvard Medical School) as an advisor to the company. Professor Bruno Conti of the Scripps Institute in La Jolla, California is also an advisor.

Longevity. Technology: Back in 2006, Conti and his team reported an exciting result in the prestigious journal Science. They showed (in female mice) that slightly reducing the metabolic rate by slightly reducing metabolic heat generation (decreasing body temperature by 0.34°C) increased lifespan by 20%.
