Published Using light to precisely control single-molecule devices



Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published New method measures the 3D position of individual atoms



Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Microalgae with unusual cell biology



A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.
Published New cardiovascular imaging approach provides a better view of dangerous plaques



Researchers have developed a new catheter-based device that combines two powerful optical techniques to image the dangerous plaques that can build up inside the arteries that supply blood to the heart. By providing new details about plaque, the device could help clinicians and researchers improve treatments for preventing heart attacks and strokes.
Published Plant Lavender, Marjoram and Ivy on your green wall to clean up the air



Green walls can strip pollution from the air -- and some plants do it better than others, according to new research. Researchers planted 10 species on a custom-built 1.4m green wall.
Published An inside look at Beech tree disease



A new study found differences at the cellular level of leaves from infected Beech trees -- variations that may account for tree mortality.
Published An evolutionary mystery 125 million years in the making



Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published Spontaneous curvature the key to shape-shifting nanomaterials



Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
Published Opening a window on the brain



Researchers have introduced a new method for in vivo brain imaging, enabling large-scale and long-term observation of neuronal structures and activities in awake mice. This method is called the 'nanosheet incorporated into light-curable resin' (NIRE) method, and it uses fluoropolymer nanosheets covered with light-curable resin to create larger cranial windows.
Published A key to the future of robots could be hiding in liquid crystals



Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.
Published Photosynthetic secrets come to light



Secrets of photosynthesis have been discovered at atomic level, shedding important new light on this plant super-power that greened the earth more than a billion years ago.
Published Researchers use liquid crystals to control polarization inside laser-written waveguides



Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable electro-optical control of polarization, which could open new possibilities for chip-based devices and complex photonic circuits based on femtosecond-written waveguides.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests



After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published Convergent evolution of algal CO2-fixing organelles



Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independent evolution of pyrenoids in different algal groups.
Published Scientists make nanoparticles dance to unravel quantum limits



The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research, scientists demonstrate a novel platform that could help us find an answer.
Published Light into the darkness of photosynthesis



Researchers succeed at generating 3D visualizations of chloroplasts' copying machines.
Published Cyber-physical heating system may protect apple blossoms in orchards



Spring frosts can have devastating effects on apple production, and a warming climate may be causing trees to blossom early, making them more susceptible to the damaging effects of extreme cold events. Growers' attempts to prevent the flowers from freezing by attempting to heat the canopies of their orchards largely have been inefficient.
Published Refrigerate lettuce to reduce risk of E. coli contamination



Leafy green vegetables are important sources of dietary fiber and nutrients, but they can harbor harmful pathogens. In particular, lettuce has often been involved in outbreaks of foodborne illness across the U.S. A new study examines factors that affect E. coli contamination on five different leafy greens -- romaine lettuce, green-leaf lettuce, spinach, kale, and collards.
Published Lake ecosystems: Nitrogen has been underestimated



An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. The result: increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish kills. Until now, controls in lake management have focused primarily on phosphorus inputs to counteract this effect. Now, this dogma is shaken by a study showing that nitrogen is also a critical driver for phytoplankton growth in lakes worldwide.
Published Small dietary changes can cut your carbon footprint by 25%



New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.
