Dehydration can affect ability to think

Drinking water has many, many health benefits. Now, add one more to the list — it can help you stay calm, particularly if you feel like losing your cool, says a new study.

Researchers at the University of Connecticut claims that even mild dehydration can have an adverse effect on the mood, especially in women. In fact, it can alter one’s mood, energy level and ability to think clearly, the ‘Daily Mail’ reported.

“Even mild dehydration — 1.5 per cent loss in normal water volume in the body — that can occur in the course of our ordinary daily activities can degrade how we are feeling, especially for women, who are more susceptible to the adverse effects of low levels of dehydration,” said Harris Lieberman, one of the researchers.

The researchers came to the conclusion after analysing results of tests which showed that it didn’t at all matter if a person had just walked for 40 minutes on a treadmill or was sitting at rest, the adverse effects were the same if they are even a bit thirsty.

Lawrence Armstrong, the lead researcher, said: “Our thirst sensation doesn’t really appear until we are one per cent or two per cent dehydrated. By then dehydration is already setting in and starting to impact how our mind and body perform.

“Dehydration affects all people, and staying properly hydrated is just as important for those who work all day at a computer as it is for marathon runners who can lose upto eight per cent of their body weight as water when they compete.”

3D microscopy to help crack Alzheimer’s secrets

Scientists have edged closer to cracking Parkinson’s and Alzheimer’s secrets with the help of cutting edge 3D microscopy.

Underwritten by neural network algorithms (artificial intelligence), the cutting-edge technology is expected to be widely used in disease research in the near future.

It will permit the automated identification, separation and analysis of cells as complex as brain’s neurons, developed jointly by Griffith’s School of Information Communication Technology (ICT) and its Eskitis Institute for Cellular and Molecular Biology (Australia).

“Scientists and clinicians will be able to superimpose multiple data sets in three dimensions using automated techniques and then conduct detailed analysis of the data in a far improved way from the two dimensional microscopy that is currently available,” said Adrian Meedeniya, according to a Griffith’s statement.“One of the main motivations for establishing this collaboration with the School of School of Information Communication Technology (ICT) was to create the technology to efficiently deal with these huge data sets,” said Meedeniya, manager of Griffith’s Imaging and Image Analysis Facility.

“We will be able to use this technology to rapidly increase our understanding of the way neuro-degenerative disorders affect nerve cell function in the brain,” added Meedeniya.
Microscopy and image acquisition technology has undergone a recent revolution, with modern microscopes generating huge multi-dimensional data sets that can easily fill an entire hard drive.

Peering into plant roots for better crops

A revolutionary technique will not only peer into plant roots with greater accuracy and clarity, but will also improve the chances of breeding better crop varieties and increasing yields.

Developed by a team from Nottingham University School of Biosciences, the new approach is based on X-ray technology used in hospital CT scans. Sacha Mooney, soil physicist at the Nottingham School of Biosciences, said: “This technique is a hugely important advance. The application of CT for visualising roots has been limited because we simply could not see a large portion of the root structure.”

A new software built into the technique can distinguish plant roots from the soil itself and other materials there, focusing only on analysing plant roots, the journal Plant Physiology reports.

The results of this research have already been demonstrated on the roots of maize, wheat and tomato, according to a Nottingham statement.
