Study confirms controversial nitrite hypothesis
Understanding how nitrite can improve conditions such as hypertension, heart attack and stroke has been the object of worldwide research studies. New research from Wake Forest University has potentially moved the science ...
Insights into plant growth could curb need for fertilizers
New insights into how plants regulate their absorption of an essential nutrient could help avoid pollution caused by excess use of fertiliser.
Atmospheric chemistry hinges on better physics model
New theoretical physics models could help us better grasp the atmospheric chemistry of ozone depletion. Indeed, understanding photoabsorption of nitrous oxide (N2O) - a process which involves the transfer of the energy of ...
Research band at Karolinska tuck Dylan gems into papers
'Nanobionics' aims to give plants super powers
Plants are an engineering marvel of nature. Fueled by sunlight, they recycle our carbon dioxide waste into fresh oxygen for us to breathe. Plus, they make the world prettier. But, with a little help from us humans, can they ...
Synthesizing textiles from sugar
In the future, the clothes you wear could be made from sugar. Researchers at the Institute of Bioengineering and Nanotechnology (IBN) have discovered a new chemical process that can convert adipic acid directly from sugar.
How do polar bears stay warm? Research finds an answer in their genes
(Phys.org) —In the winter, brown and black bears go into hibernation to conserve energy and keep warm.
Sniffed out: The 'gas detectors' of the plant world
The elusive trigger that allows plants to 'see' the gas nitric oxide (NO), an important signalling molecule, has been tracked down by scientists at The University of Nottingham. It is the first time that a central mechanism ...
Choreographed stages of Salmonella infection revealed
Scientists have used a new method to map the response of every salmonella gene to conditions in the human body, providing new insight into how the bacteria triggers infection.
Nanotube-based sensors can be implanted under the skin for a year
Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, ...
The root of the matter: The role of nitric oxide in root branching
The structure and plasticity of root systems play an important role in determining the growth and yield of crop plants, and understanding how environmental and biological factors affect root structure is of key importance ...
Pollution-fighting algae: Algae species holds potential for dual role as pollution reducer, biofuel source
(Phys.org) —A hardy algae species is showing promise in both reducing power plant pollution and making biofuel, based on new research at the University of Delaware.
When green algae run out of air: Single cell organisms need haemoglobin to survive in an oxygen-free environment
When green algae "can't breathe", they get rid of excess energy through the production of hydrogen. Biologists at the Ruhr-Universität Bochum have found out how the cells notice the absence of oxygen. For ...
