Inaction on the water crisis could put more than half of the world’s food production at risk by 2050, experts warned in a major report published Thursday.
While infrared cameras are valuable tools for enhanced vision, food and plant quality control, security, etc, today’s cameras often face significant drawbacks. For instance, they are bulky and power-hungry, requiring cooling systems that limit their functionalities.
More importantly, current semiconductor-based technology used in the cameras only captures a narrow band of the infrared spectrum based on the absorption band of the semiconductor detector. This means that every application would need a separate camera.
“Due to the complications of today’s bulky, power-hungry and expensive infrared imaging technology, we are unlikely to have an infrared camera at home. However, nonlinear frequency conversion, a process that manipulates and translates electromagnetic signals across various frequency regimes, holds a massive potential to revolutionize infrared detection technology,” said Prof Mohsen Ramhami, the leader of Advanced Optics and Photonics Lab, and a UK Research and Innovation Future Leaders Fellow.

Fever temperatures rev up immune cell metabolism, proliferation and activity, but they also — in a particular subset of T cells — cause mitochondrial stress, DNA damage and cell death, Vanderbilt University Medical Center researchers have discovered.
The findings, published Sept. 20 in the journal Science Immunology, offer a mechanistic understanding for how cells respond to heat and could explain how chronic inflammation contributes to the development of cancer.
The impact of fever temperatures on cells is a relatively understudied area, said Jeff Rathmell, PhD, Cornelius Vanderbilt Professor of Immunobiology and corresponding author of the new study. Most of the existing temperature-related research relates to agriculture and how extreme temperatures impact crops and livestock, he noted. It’s challenging to change the temperature of animal models without causing stress, and cells in the laboratory are generally cultured in incubators that are set at human body temperature: 37 degrees Celsius (98.6 degrees Fahrenheit).
Researchers have long observed that a common family of environmental bacteria, Comamonadacae, grow on plastics littered throughout urban rivers and wastewater systems.
Finding could lead to bioengineering solutions to clean up plastic waste.
A new study finds that a common bacterium can break down plastic for food, opening new possibilities for bacteria-based engineering solutions to help clean up plastic waste. Illustration credit Ludmilla Aristilde/Northwestern University.

Researchers from the Sapienza University of Rome found that caffeine has a positive effect on endothelial cells, a group of cells responsible for vascular regeneration.
We studied the role of caffeine intake on endothelial function in SLE by assessing its effect on circulating endothelial progenitor cells (EPCs) both ex vivo in SLE patients and in vitro in healthy donors (HD) treated with SLE sera.
Methods.
New research from North Carolina State University shows that unique materials with distinct properties akin to those of gecko feet – the ability to stick to just about any surface – can be created by harnessing liquid-driven chaos to produce soft polymer microparticles with hierarchical branching on the micro-and nanoscale.
The findings, published today (October 14, 2019) in the journal Nature Materials, hold the potential for advances in gels, pastes, foods, nonwovens, and coatings, among other formulations.
The soft dendritic particle materials with unique adhesive and structure-building properties can be created from a variety of polymers precipitated from solutions under special conditions, says Orlin Velev, S. Frank and Doris Culberson Distinguished Professor of Chemical and Biomolecular Engineering at NC State and corresponding author of the paper.
Genetic analysis of cavity crud from two famed man-eating lions suggests the method could re-create diets of predators that lived thousands of years ago.
