According to some estimates, up to one in three people around the world may experience severe anxiety in their lifetime. In a study described today in Cell Reports, researchers at the Weizmann Institute of Science have revealed a previously unknown mechanism underlying anxiety. Targeting this biochemical pathway may help develop new therapies for alleviating the symptoms of anxiety disorders.
In a new study published online this week in the Proceedings of the National Academy of Sciences, chemistry professor Victor Batista and his colleagues used the Google algorithm PageRank to identify key amino acids in the regulation of a bacterial enzyme essential for most microorganisms.
Researchers have genetically transformed the Common Primrose (Primula vulgaris) for the first time in a development that could shed light on one of the plant world's most renowned reproductive systems.
EPFL researchers have developed a method to observe the electrical activity of neurons by analyzing the behavior of surrounding water molecules. This simple and non-invasive method, which could eliminate the need for electrodes and fluorophores, can be used to monitor the activity within a single neuron or potentially on an entire region of the brain.
A new Northwestern University study has found that an antimicrobial chemical called triclosan is abundant in dust -- and linked to changes in its genetic makeup. The result is dust with organisms that could cause an antibiotic-resistant infection.
Rotator Cuff tears affect 15 percent of 60 year olds and carry a significant social and financial burden. Current operative techniques and repair adjuncts are associated with unacceptably high failure rates, stimulating investigation into novel tissue engineering and regenerative medicine (TERM) approaches in the field of rotator cuff surgery. In this review researchers explore the most recent advances in the field of electrospinning, focussing on proposed tissue-engineered solutions in tendon, specifically the rotator cuff.
A new study from Columbia Engineering and Columbia University Irving Medical Center shows that avoidant grievers unconsciously monitor and block the contents of their mind-wandering, a discovery that could lead to more effective psychiatric treatment for bereaved people. The researchers, who studied 29 bereaved subjects, are the first to show how this unconscious thought suppression occurs.
Researchers from three research institutes in Spain have developed a biotechnological tool to produce, in a very efficient manner, antifungal proteins in the leaves of the plant Nicotiana benthamiana. These proteins are promising biomolecules that could be used to develop new antifungals whose properties and mechanisms of action represent improvements on the existing ones, and which can be applied in diverse fields, including crop and postharvest protection and animal and human health.
Materials scientists at Rensselaer Polytechnic Institute have found that oscillating loads at certain frequencies can lead to several-fold increases in the strength of composites with an interface that is modified by a molecular layer of 'nanoglue.'
Animals are much better at smelling a complex 'soup' of odorants rather than a single pure ingredient, a new study by the University of Sussex has revealed.
