Next-generation hydrogels can form synthetic scaffolds to support the formation of replacement tissues and organs in the emerging area of regenerative medicine.

Embedding peptides into the hydrogels stimulates the growth of essential microvascular networks to ensure a good blood supply.  A new paper describes the technology in which hydrogels functionalized with laminin-derived peptides were transplanted in a mouse cornea and were shown to support cell growth and blood vessel formation.

Tropical climates that allow for year-round farming have a tremendous economic advantage, even in the developing world but corn and soybean farmers in Mato Grosso, Brazil have a developed world problem;a 10 percent post-harvest loss, partially due to a lack of storage. 

A research project used Geographic Information System (GIS) software to map the coordinates of commercial, cooperative and private grain storage facilities in Mato Grosso. They focused on capacity greater than 50,000 metric tons, mapping the state's 2,143 registered warehouses. 

Our prehistoric close cousins, the Neandertals, were more similar than science used to think in a variety of ways.

And according to a new paper, they had something resembling modern speech and language, which can be traced back to the last common ancestor we shared with the Neandertals roughly half a million years ago.

Neanderthals have fascinated the academic world and the general public ever since their discovery almost 200 years ago. Initially thought to be sub-human brutes incapable of anything but the most primitive of grunts, they were later found to be a successful form of humanity inhabiting vast swathes of western Eurasia for several hundreds of thousands of years, during harsh ages and milder interglacial periods. 

As Egypt fights over new leadership, Israeli archaeologists have found evidence of an ancient ruler in northern Israel. 

At a site in Tel Hazor National Park, north of the Sea of Galilee, archaeologists from the Hebrew University of Jerusalem have unearthed part of a unique Sphinx belonging to one of the ancient pyramid-building pharaohs. The Sphinx was brought over from Egypt, with a hieroglyphic inscription between its front legs that bears the name of the Egyptian king Mycerinus, who ruled in the third millennium BCE, more than 4,000 years ago and was one of the builders of the famous Giza pyramids. 

Wildfires and their witch's brew of carbon-containing particles significantly degrade air quality, damage human and wildlife health, and interact with sunlight to affect climate.

Measurements taken during the 2011 Las Conchas fire near Los Alamos National Laboratory show that the actual carbon-containing particles emitted by fires are very different than those used in numerical models, providing the potential for inaccuracy in current climate-modeling results.

When the members of a choir sing their heart beats are synchronized, according to a study from the Sahlgrenska Academy at University of Gothenburg.

The pulse of performing choir members tend to increase and decrease in unison. 

In the research project "Kroppens Partitur" (The Body's Musical Score), researchers at the Sahlgrenska Academy are studying how music, in purely biological terms, affects our body and our health. The object is to find new forms where music may be used for medical purposes, primarily within rehabilitation and preventive care and the research group says they were able to show how the musical structure influences the heart rate of choir members.
