Study finds elevated soil lead levels in formerly industrial residential NYC neighborhoods
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
Over the past 20 years, many areas within New York City have transitioned from industrial and manufacturing zones to residential neighborhoods. This brings families with young children to areas with a legacy of historic lead contamination in the soil.
TESS delivers new insights into an ultrahot world
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"...
World's widest graphene nanoribbon promises the next generation of miniaturized electronics
Measurements from NASA's Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of the bizarre environment of KELT-9 b, one of the hottest planets known.
Bubbling and burping droplets of DNA
With literally the thickness of one carbon atom and electrical properties that can surpass those of standard semiconductor technologies, graphene nanoribbons promise a new generation of miniaturized electronic devices. The theory, however, remains far ahead of reality, with current graphene nanoribbons falling short of their potential.
Racist cop shows and biased news fuel public fears of crime and love for the police
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.
Researchers find large linear negative thermal expansion in intermetallic Cr-Se-Te compounds
Earlier this month, President Donald Trump tweeted that defunding the police would "be good for Robbers & Rapists." Last week, after signing his tepid executive order on policing, he proffered that "without police, there is chaos."
Scientists develop N-doped self-cleaning membranes that use visible light irradiation
Researchers used a variable temperature X-ray diffractometer (XRD) at China's Steady High Magnetic Field Facility (SHMFF) under Hefei Institutes of Physical Science and have found large linear negative thermal expansion in intermetallic Cr-Se-Te Compounds. This research was published in Inorganic Chemistry.
Wild bees depend on the landscape structure
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Argonne National Laboratory in the U.S. have recently employed atomic layer deposition (ALD) to fabricate visible light-activated membranes that efficiently use solar energy.
Chanterelle mushrooms as a taste enhancer
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...
Microplastic pollution accumulates heavily in coastal areas such as fjords and estuaries
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
Microplastic pollution in marine environments is concentrated most highly in coastal habitats, especially fjords and estuaries, according to a new review article published in the journal Marine Pollution Bulletin. Deep sea environments generally have much lower microplastic concentrations, although there are hotspots where elevated concentrations of microplastic occur.
NASA catches a short-lived Eastern Pacific Depression 4E
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...
Brain receptor pulls open electrical gate like a puppet master
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.
To find giant black holes, start with Jupiter
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...
Versatile LED irradiation system: From disinfection to medical treatments
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
For disinfection purposes, a compact system can be equipped with UV LEDs to eliminate germs on critical surfaces such as mobile phones. It can also be assembled with LEDs providing the optimum emission spectrum for polymer curing and medical treatments—even multiple wavelengths are possible.
Study finds plastic recycling from Europe being dumped in Asian waters
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
New research from NUI Galway and the University of Limerick has for the first time quantified the volume of plastic from European countries (EU, UK, Switzerland and Norway) that contributes to ocean littering from exported recycling.
Ultrafast light wave electronics: Light from inside the tunnel
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.

Life-hack: Rituals spell anxiety relief
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.
