Observing quantum coherence from photons scattered in free-space

Eurekalert - Jun 10 2021 - 00:06
Sending photons encoded with quantum information through free-space for applications like quantum communication and imaging are currently limited to channels with direct line-of-sight and low-noise. Researchers at University of Waterloo, Canada, have demonstrated a technique to encode quantum information in photons that will survive scattering from diffuse objects, while recording an image. This research could open up new possibilities for non-line-of-sight quantum channels and broaden the application of quantum communications or imaging to scattered signals.

Changing community networks impact disease spread

Eurekalert - Jun 10 2021 - 00:06
The COVID-19 pandemic has made clear the importance of understanding precisely how diseases spread throughout networks of transportation. In a paper publishing on Thursday in the IAM Journal on Applied Mathematics, Stephen Kirkland (University of Manitoba), Zhisheng Shuai (University of Central Florida), P. van den Driessche (University of Victoria), and Xueying Wang (Washington State University) study the way in which changes in a network of multiple interconnected communities impact the ensuing spread of disease.

New methods needed to boost success of Classical Biological Control to fight insect pests

Eurekalert - Jun 10 2021 - 00:06
A CABI-led study has revealed that the success of Classical Biological Control (CBC) in Europe, North Africa and the Middle East is only rarely dependent on the released biological control agent, but more often on other factors, such as the target pest, its host plant, or the circumstances of the releases.

Researchers use transoceanic fiber link for geophysical sensing

Eurekalert - Jun 10 2021 - 00:06
In a new study in Optica, The Optical Society's journal for high impact research, researchers show that the fiber optic cables that carry data across the world's oceans can also be used to sense geophysical events and monitor ocean and seafloor conditions.

Latest tests on 6G return surprising results

Eurekalert - Jun 10 2021 - 00:06
Researchers have long believed that as we move up into 6G frequency, the ways in which a signal can reach a receiver will be greatly limited. New research shows that this is not always accurate..Making 6G technology a reality is an important step towards realizing a whole host of new applications including haptic internet, mobile edge computing, and holographic communications. All three of these areas have the potential to change the face of communications, health, transportation, education, and more.

Bacteria hijack latent phage of competitor

Eurekalert - Jun 10 2021 - 00:06
Bacteriophages are still a relatively unknown component of the human microbiome. However, they can play a powerful role in the life cycles of bacteria. Biochemist Thomas Böttcher from the University of Vienna and Ph.D. student Magdalena Jancheva were able to show for the first time how Pseudomonas bacteria use a self-produced signal molecule to selectively manipulate phages in a competing bacterial strain to defeat their enemy.

'Bad fat' suppresses killer T cells from attacking cancer

Eurekalert - Jun 10 2021 - 00:06
Salk researchers have identified how tumors cause immune cells to lose their ability to fight cancer, by producing harmful fats the energy-hungry immune cells ingest, impairing their functionality. The understanding opens new avenues for novel immunotherapies for cancer.

Sealed, signed and delivered

Eurekalert - Jun 10 2021 - 00:06
A team of archaeologists from the Hebrew University of Jerusalem (HU) made a rare discovery when they unearthed a small clay seal impression dating back some 7,000 years. The impression, with two different geometric stamps imprinted on it, was discovered in Tel Tsaf, a prehistoric village located in Israel's Beit She'an Valley up north.

Trapping DNA damage

Eurekalert - Jun 10 2021 - 00:06
The delicate strands that carry life's genetic code take a beating as they jumble about in the course of their work. If left untreated, errors accumulate, with fatal consequences for the organism. This is where two key proteins come to the rescue: PARP acts as a marker for a trouble spot, allowing XRCC1 to zoom in and begin a repair.

Study of harvey flooding aids in quantifying climate change

Eurekalert - Jun 10 2021 - 00:06
Researchers from Lawrence Berkeley National Laboratory and Fathom Bristol used a hydraulic model to consider the degree to which human-caused climate change may have affected flooding in Houston in 2017 during Hurricane Harvey. Resources at the National Energy Research Scientific Computing Center were used to quantify the increase in Houston flood area and depth and to host a portal where other scientists and the public can access and explore the resulting data.

Ion and lipid transporters specialize for their niche

Eurekalert - Jun 10 2021 - 00:06
Cell viability require that a variety of functions at the cell membrane are maintained properly. P-type ATPases translocate substrates across the membrane, and they have evolved into different types taking care of specific substrates within a diverse range. Now, key structural aspects have been described on how two different types of P-type ATPases -- a Ca2+ transporting Ca2+-ATPase and a lipid transporting P4-ATPase - have adapted to different substrates and physical environments.

A new mechanism behind continuous stem cell activity in plants

Eurekalert - Jun 10 2021 - 00:06
An inter-university research group has succeeded in constructing the gene expression network behind the vascular development process in plants. They achieved this by performing bioinformatics analysis using the 'VISUAL' tissue culture platform, which generates vascular stem cells from leaf cells. In this network, they also discovered a new BES/BZR transcription factor, BEH3, and illuminated its role in vascular cell maintenance.

Nicotinamide can 'immunize' plants to protect from fungal disease

Eurekalert - Jun 10 2021 - 00:06
A team led by Kanazawa University, Japan, discovered that applying the vitamin nicotinamide (NIM) to plants prevents development of fungal disease. Pre-treatment with NIM activates the plant immune response and increases amounts of antimicrobial compounds that suppress the growth of the fungus. The results could lead to novel approaches to tackling crop diseases, potentially replacing toxic fungicide sprays with new, safer ways to stimulate the plant's own defense systems.

When physics meets financial networks

Eurekalert - Jun 10 2021 - 00:06
Financial institutions are linked together in a global web of interactions whose structure can be analyzed quantitatively by means of network theory. Today, 15 years after the 2007-2008 financial crisis, the role of networks for monitoring financial stability is widely recognized. Both policymakers and researchers agree that systemic risk has to be studied and managed by adopting a network perspective.
