Yukiko Yamashita thought she knew the fruit-fly testis inside out. But when she carried out a set of experiments on the organ five years ago, it ended up leaving her flummoxed.Her group had been studying how fruit flies maintain their sperm supply and had engineered certain cells involved in the process to produce specific sets of proteins. But instead of showing up in the engineered cells, some proteins seemed to have teleported to a different group of cells entirely.

Five Ways India Changed the World With Math

It should come as no surprise that the first recorded use of the number zero, recently discovered to be made as early as the 3rd or 4th century, happened in India. Mathematics on the Indian subcontinent has a rich history going back over 3,000 years and thrived for centuries before similar advances were made in Europe, with its influence meanwhile spreading to China and the Middle East.

The latest fiery exchange between the United States and North Korea has produced a new kind of threat. On Tuesday, during his speech at the United Nations, President Trump said his government would totally destroy North Korea if necessary to defend the United States or its allies. On Friday, Kim Jong Un responded, saying North Korea will consider with seriousness exercising of a corresponding, highest level of hard-line countermeasure in history.

High Energy Cosmic Rays Come From Beyond Galaxy

When it comes to the highest energy cosmic rayssubatomic particles raining in from spacethe sky is lopsided: More come from one direction than the other, according to a new study. And because most come from a direction that points away from our galaxy, the observation bolsters the idea that the cosmic rays originate far beyond the Milky Way. However, the result falls short of astrophysicists' goal of pinpointing the ultimate sources of such cosmic rays.

Gravitational Waves May Oscillate Like Neutrinos

Using data from the first-ever gravitational waves detected last year, along with a theoretical analysis, physicists have shown that gravitational waves may oscillate between two different forms called "g" and "f"-type gravitational waves. The physicists explain that this phenomenon is analogous to the way that neutrinos oscillate between three distinct flavorselectron, muon, and tau. The oscillating gravitational waves arise in a modified theory of gravity called bimetric gravity, or "bigravity," and the physicists show that the oscillations may be detectable in future experiments.

The Big Bang Wasn't the Beginning

The Universe began not with a whimper, but with a bang! At least, that's what you're commonly told: the Universe and everything in it came into existence at the moment of the Big Bang. Space, time, and all the matter and energy within began from a singular point, and then expanded and cooled, giving rise over billions of years to the atoms, stars, galaxies, and clusters of galaxies spread out across the billions of light years that make up our observable Universe.

Advanced Life May Exist in a Form Beyond Matter

22 September 2017 - 12:22am
The Daily Galaxy
Astrophysicist Paul Davies at Arizona State University suggests that advanced technology might not even be made of matter. That it might have no fixed size or shape; have no well-defined boundaries. Is dynamical on all scales of space and time. Or, conversely, does not appear to do anything at all that we can discern. Does not consist of discrete, separate things; but rather it is a system, or a subtle higher-level correlation of things.

Are We About to See a Black Hole?

Adam Frank, NPR
If there is one thing science is good for, it's going to extremes.A lot of science's history is just one story after another of people figuring out how to do something that, just a few years before, was thought to be impossible.The impossible was heavy on my mind last Wednesday as I found out just how close we were to seeing as in taking actual pictures of black holes.
