Imagine a future in which you could 3D-print an entire robot or stretchy, electronic medical device with the press of a button – no tedious hours spent assembling parts by hand.

That possibility may be closer than ever thanks to a recent advancement in 3D-printing technology led by engineers at the University of Colorado Boulder. In a new study, the team lays out a strategy for using currently-available printers to create materials that meld solid and liquid components – a tricky feat if you don’t want your robot to collapse.

The early universe may chirp about unknown physics. A University of Helsinki research team has demonstrated how an early universe phase transition will lead to gravitational wave signals potentially visible in the upcoming satellite missions. The research results were recently published in the journal Physical Review Letters.

Phase transitions, such as the boiling of water or the melting of a metal, are commonplace but fascinating phenomena that spur surprises decades after decades...

A research group at Karolinska Institutet in Sweden has analysed how certain immune cells known as innate lymphoid cells (ILCs) develop into mature cells that play a part in inflammatory bowel disease (IBD). The findings could pave the way for more effective treatments against IBD, a disease that causes considerable suffering and that is linked to an increased risk of colorectal cancer. The results are published today in the journal Science Immunology.

Inflammatory bowel disease (IBD) is characterised by a chronic inflammation of the gut mucosa that is thought to increase the risk of colon cancer. The disease often debuts before middle age with symptoms such as abdominal pain and weight loss...

Turmeric, a spice found in most kitchens, has an extract that could lead to safer, more efficient fuel cells.

Researchers at the Clemson Nanomaterials Institute (CNI) and their collaborators from the Sri Sathya Sai Institute of Higher Learning (SSSIHL) in India discovered a novel way to combine curcumin—the substance in turmeric—and gold nanoparticles to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.

While the research...
