Turning wastewater into a resource

A team of European researchers and engineers initiated the ULTIMATE project to turn wastewater into a resource. This initiative is co-financed by the European Commission and started in June 2020. The aim is to create economic value and increase sustainability by valorising resources within the water cycle.

Density, equity, and the history of epidemics in New York City

New York City's current responses to COVID-19 have a lot in common with the long history of epidemics that have devastated the health and well-being of the city's population. Today, as during the epidemics that scourged New York in the 19th century, those most affected are those most essential to the functioning of the economy. Also revived is the question of the efficacy of "social distancing"...

Bubbling and burping droplets of DNA

Liquid droplets formed from DNA display a peculiar response to enzymes. An international collaboration between LMU and UCSB has now been able to explain the mechanisms behind bubble formation.

Wild bees depend on the landscape structure

Sowing strips of wildflowers along conventional cereal fields and the increased density of flowers in organic farming encourage bumblebees as well as solitary wild bees and hoverflies. Bumblebee colonies benefit from flower strips along small fields, but in organic farming, they benefit from large fields. This research was carried out by agroecologists from the University of Göttingen in a...

Chanterelle mushrooms as a taste enhancer

Chanterelles (Cantharellus cibarius) are one of the most popular mushrooms in Germany. Depending on the weather, chanterelle season starts in early July. Connoisseurs value the mushroom's delicate fruity aroma, which is reminiscent of apricots, and its aromatic and slightly bitter taste profile. Not only do chanterelles have a unique flavor profile, they also function as taste enhancers, lending...

Plant tissue engineering improves drought and salinity tolerance

After several years of experimentation, scientists have engineered thale cress, or Arabidopsis thaliana, to behave like a succulent, improving water-use efficiency, salinity tolerance and reducing the effects of drought. The tissue succulence engineering method devised for this small flowering plant can be used in other plants to improve drought and salinity tolerance with the goal of moving this...

NASA catches a short-lived Eastern Pacific Depression 4E

Tropical Depression 4E formed late on June 29 and it is forecast to become a remnant low-pressure area by the end of the day on June 30. NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the depression, located just southwest of the southern tip of Mexico's Baja Peninsula.

Brain receptor pulls open electrical gate like a puppet master

For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals. Critical for brain development and function, the receptor converts chemical messages between cells into electrical signals within a neuron. The key to transmitting that information is opening the...

To find giant black holes, start with Jupiter

The revolution in our understanding of the night sky and our place in the universe began when we transitioned from using the naked eye to a telescope in 1609. Four centuries later, scientists are experiencing a similar transition in their knowledge of black holes by searching for gravitational waves.

Buzzing to rebuild broken bone

Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, UConn engineers reported on June 27 in the Journal of Nano Energy.

Pandemic reveals opportunities for 5G connectivity

5G cellular technology, which has been promised to provide a connective fabric that will cover the globe in a seamless digital experience, is starting to take shape. But the coronavirus pandemic of 2020 that has forced hundreds of millions of people to work and socialize remotely has made it clear that the connective fabric is still missing a few stitches. This article was produced by Insights,...

Ultrafast light wave electronics: Light from inside the tunnel

Steering and monitoring the light-driven motion of electrons inside matter on the time-scale of a single optical cycle is a key challenge in ultrafast light wave electronics and laser-based material processing. Physicists have now revealed a so-far overlooked nonlinear optical mechanism that emerges from the light-induced tunneling of electrons inside dielectrics.

Spider silk can create lenses useful for biological imaging

Spider silk is useful for a variety of biomedical applications: It exhibits mechanical properties superior to synthetic fibers for tissue engineering, and it is not toxic or harmful to living cells. One unexpected application for spider silk is its use in the creation of biocompatible lenses for biological imaging applications. Researchers now describe the feasibility of creating lenses...

Revisiting energy flow in photosynthetic plant cells

By developing innovative methods to visualize energy changes in subcellular compartments in live plants, researchers recently solved a controversial question in photosynthesis: what is the source of NADH (Reduced Nicotinamide adenine dinucleotide) for mitochondria to generate ATP (Adenosine triphosphate)?
