Secondary forests restore fresh water sources in degraded landscapes

New research, published in Scientific Reports by Smithsonian Tropical Research Institute (STRI) postdoctoral fellow Karina Chavarria and colleagues, shows that bacterial communities in streams adjacent to young secondary forests recover to resemble those of mature forest streams in as little as a decade after cattle has been removed from the land, and that these communities are robust throughout...

When macrophages let off steam

New data shows how inflammatory reactions can be resolved by changes to the metabolism of macrophages. Danger signals released by damaged cells during inflammation play a role during this process. 'Rewiring' the mitochondria in the macrophages protects them against overloading and can thus improve the way in which parts of damaged cells are eliminated and resolve the inflammatory reaction.

The Guardian view on Roman Britain: a constantly shifting picture | Editorial

New discoveries are constantly reshaping and enriching the story of our pastThe novelist and philosopher Iris Murdoch once wrote that the study of early Greek history “sets a special challenge to the disciplined mind. It is a game with very few pieces, where the skill of the player lies in complicating the rules.” The same could be said of the study of Britain’s Roman period, a long, often...

Employment for people with disabilities reaches historic levels

In October, the major employment indicators for people with disabilities reached their highest recorded levels since September 2008, when reporting for this cohort was begun by the Bureau of Labor Statistics (BLS), according to today's National Trends in Disability Employment—Monthly Update (nTIDE), issued by Kessler Foundation and the University of New Hampshire's Institute on Disability...

Fractured artificial rock helps crack a 54-year-old mystery

Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and sedimentary rocks. The findings could help improve many important processes in energy, environmental and industrial sectors, from oil recovery to groundwater remediation.

Electron family creates previously unknown state of matter

An international research team has demonstrated a completely novel state of matter in a metal. It is created by the combination of four electrons-until now, only electron pairs were known. This discovery could lead to a new type of superconductivity, an entirely new research direction, and revolutionary technologies such as quantum sensors.

How cells correctly choose active genes

It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers have now found that the formation of transcription factories resembles the condensation of liquids. Their findings will improve the understanding of causes of diseases and advance the development...

New strategy against treatment-resistant prostate cancer identified

A new study has identified an RNA molecule that suppresses prostate tumors. The scientists found that prostate cancers develop ways to shut down this RNA molecule to allow themselves to grow. According to the new research -- conducted in mice implanted with human prostate tumor samples -- restoring this so-called long noncoding RNA could be a new strategy to treat prostate cancer that has...

Experts master defects in semiconductors

Researchers have discovered a novel way to manipulate defects in semiconductors. The study holds promising opportunities for novel forms of precision sensing, or the transfer of quantum information between physically separate qubits, as well as for improving the fundamental understanding of charge transport in semiconductors.

I Traveled the World to Witness the End of Winter

For a century and a half, melting snow and ice have been the most recognizable visual evidence of climate change. You can see it in the Arctic Ocean, where the first ice-free summer in two and a half million years is predicted by 2035; in the Alps, where half of the range’s iconic glacial ice…
