How chromosomes evolve to create new forms of life

3-D printing is a universal process in the sense that pretty much any part that can be drawn up in a CAD program can be printed, at least within a certain resolution. Machining a part on a mill or lathe, while having the ...

Astronomers discover new candidate redback millisecond pulsar

Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting ...

Researchers reveal recipe for engineering ribosomes

Ribosomes are complex molecular machines in the cell that catalyze the production of proteins. Ahmed Badran, a Broad Fellow at the Broad Institute of MIT and Harvard, and his lab aim to engineer new kinds of ribosomes that ...

OSIRIS-REx mission plans for May asteroid departure

Since its launch in September 2016, the OSIRIS-REx spacecraft has traveled billions of miles, mapped the surface of an asteroid in unprecedented detail, and made new scientific discoveries about near-Earth asteroids. Now, ...

Ancient proteins help track early milk drinking in Africa

Tracking milk drinking in the ancient past is not straightforward. For decades, archaeologists have tried to reconstruct the practice by various indirect methods. They have looked at ancient rock art to identify scenes of ...

Carbon-chomping soil bacteria may pose hidden climate risk

Much of the earth's carbon is trapped in soil, and scientists have assumed that potential climate-warming compounds would safely stay there for centuries. But new research from Princeton University shows that carbon molecules ...

Extreme black holes have hair that can be combed

Black holes are considered amongst the most mysterious objects in the universe. Part of their intrigue arises from the fact that they are actually among the simplest solutions to Einstein's field equations of general relativity. ...

Putting bugs on the menu, safely

The thought of eating insects is stomach turning for many, but new Edith Cowan University (ECU) research is shedding light on allergy causing proteins which could pose serious health risks for those suffering from shellfish ...

A CubeSat will test out water as a propulsion system

Novel propulsion systems for CubeSats have been on an innovative tear of late. UT has reported on propulsion systems that use everything from solid iodine to the Earth's own magnetic field as a way of moving a small spacecraft. ...

Arctic ocean expedition advances climate modeling

As the climate warms and Arctic sea ice retreats, more research vessels and commercial ships are sailing into the Arctic Ocean, but the accuracy and sensitivity of regional weather and marine forecasts for these hazardous ...

Making wheat and peanuts less allergenic

The United States Department of Agriculture identifies a group of "big eight" foods that causes 90% of food allergies. Among these foods are wheat and peanuts.

The naming of Tooley crater

Like Einstein, Galileo, and Copernicus, former NASA program manager Craig Tooley now has a place on the Moon named in his honor. Tooley crater is a 7 km crater in a permanently shadowed region of Shoemaker crater near the ...

Cell 'bones' mystery solved with supercomputers

Our cells are filled with 'bones,' in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, ...
