The influence of plant photosynthetic indices on the effectiveness of PRI use

Jul 19 2018 - 00:07
In the framework of the actively developing practice of "precision farming", Lobachevsky University researchers are working to develop and introduce methods for spatially heterogeneous treatment of plants that minimize costs and improve the ecological quality of the crops, due to the less intensive use of chemical compounds.

Binge drinking during adolescence impairs working memory, finds mouse study

Jul 19 2018 - 00:07
Using a mouse model to simulate binge drinking, researchers at Columbia University showed that heavy alcohol use during adolescence damages neurons in the part of the brain involved in working memory.

Monkeys benefit from the nut-cracking abilities of chimpanzees and hogs

Jul 19 2018 - 00:07
Researchers of the University of Amsterdam and the Max Planck Institute for Evolutionary Anthropology describe for the first time the scavenging behaviour of mangabey monkeys, guinea fowls, and squirrels on energy-rich nut remnants cracked by chimpanzees and red river hogs. The team used data collected by camera traps in the rain forest of Tai National Park in Ivory Coast. The results reveal new unknown interactions between different species and increase our understanding of the complex community of animals foraging around tropical nut trees.

High fruit and vegetable consumption may reduce risk of breast cancer

Jul 19 2018 - 00:07
Women who eat a high amount of fruits and vegetables each day may have a lower risk of breast cancer, especially of aggressive tumors, than those who eat fewer fruits and vegetables, according to a new study led by researchers from Harvard T.H. Chan School of Public Health.

Deadly Rift Valley fever: New insight, and hope for the future

Jul 19 2018 - 00:07
Health control measures alone could be ineffective in the long term fight against the deadly Rift Valley fever which affects both humans and animals, a new study in the journal PNAS reports.

Most common shoulder operation is no more beneficial than placebo surgery

Jul 19 2018 - 00:07
In a landmark study published this week in the BMJ, Finnish researchers show that one of the most common surgical procedures in the Western world is probably unnecessary. Keyhole surgeries of the shoulder are useless for patients with 'shoulder impingement', the most common diagnosis in patients with shoulder pain.

China's 'livestock revolution' demands 'new transition'

Jul 19 2018 - 00:07
Demand for animal protein and increasing wealth fuelled a tripling in the domestic production of livestock in China between 1980 and 2010, and the rise, despite some improvements in efficiencies at the farm level, had significant impacts on environmental sustainability, nationally and globally. The country's scientists are now aiming to redress the balance.

A social tool for evaluating the environmental impact of residential buildings

Jul 19 2018 - 00:07
for the first time, an open-source computing tool can, simply and intuitively, calculate the CO2 emissions in each phase of a building project, in order to obtain a global picture of its carbon footprint from its conception and to help decide every variable in the construction process.

Aggressive immune cells aggravate Parkinson's disease

Jul 19 2018 - 00:07
Parkinson's disease, formerly also referred to as shaking palsy, is one of the most frequent disorders affecting movement and the nervous system. Medical researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have come across a possible cause of the disease - in the patients' immune system.

Infrared sensor as new method for drug discovery

Jul 19 2018 - 00:07
Using an infrared sensor, biophysicists at Ruhr-Universität Bochum (RUB) have succeeded in analysing quickly and easily which active agents affect the structure of proteins and how long that effect lasts. Thus, Prof Dr Klaus Gerwert and Dr Jörn Güldenhaupt performed time-resolved measurements of the changes to the structure of protein scaffolds, which were triggered by the active agents. Their methods might help develop drugs with little side effects in a quick and targeted manner.

Scientists reveal the links between deep carbon cycle and geodynamics of big mantle wedge

Jul 19 2018 - 00:07
The formation age of the big mantle wedge beneath eastern Asia and the lithospheric thinning mechanism of the North China craton are two key scientific issues. Based on new findings of deep carbon cycle, a recent study suggests that the big mantle wedge beneath eastern Asia was formed 125 Ma, and interaction between the CO2-rich silicate melt produced in the big mantle wedge and lithospheric mantle results in lithospheric thinning of the North China craton.

Robots working as a group are able to determine the optimal order of their tasks

Jul 19 2018 - 00:07
Could robots soon help rescue crews save the survivors of a natural disaster? Such a mission would require that the robots be able to determine, on their own, which tasks to perform and in what order to perform them. Researchers at ULB's IRIDIA laboratory have shown, for the first time, that this ability can emerge from a group of robots.

Building blocks of life

Jul 19 2018 - 00:07
A collaborative research team based in Japan has designed new proteins that can self-assemble into the complex structures underlying biological organisms, laying the groundwork for leading-edge applications in biotechnology. The researchers created and developed the proteins with a specific function and their method reveals a possibility that certain protein functions can be created on demand. It is expected to contribute to the development of nanobiomaterials, which could be used as a drug delivery system or an artificial vaccine.

The effectiveness of chlorhexidine is limited in preventing infections in oral procedures

Jul 19 2018 - 00:07
A large number of bacteria are present in human mouths and may pass into the blood when procedures such as the removal of a tooth are carried out. Chlorhexidine mouthwashes have a powerful antimicrobial effect, but there are opposing positions on its use in these cases. The research by the UPV/EHU shows that its use would prevent 12 percent of cases of bacteraemia.

Reconstruction of Arctic Barents-Kara sea ice extent changes over the last millennium

Jul 19 2018 - 00:07
The Arctic Barents-Kara Sea is considered as one of the cradles for cold waves over the Eurasian continent, and it's a key sea sector that is closely connected with cold waves over Eurasia. A recent research published on the Science China Earth Sciences has shown the sea ice extent variations of this sea area over the last millennium.
