Controlling the function of nerve cells that mediate perception of painful stimuli
Chemical biologists at LMU have synthesized a set of molecules which make it possible to optically control the function of nerve cells that mediate perception of painful stimuli.
Combining magnetism and light to fight cancer
By combining, in a liposome, magnetic nanoparticles and photosensitizers that are simultaneously and remotely activated by external physical stimuli (a magnetic field and light), scientists at the Laboratoire ...
'Draw me a picture,' say scientists: Computer may respond
Like the rest of us, scientists wish they could just ask a computer a question and have it respond with an answer presented in an easy-to-understand picture. Today's visualization tools can translate huge ...
Virtual stimuli help identify deviant sexual behaviors
Virtual reality may be the key to predicting both the behaviour of sex offenders and the effectiveness of the therapies they have undergone, according to a study undertaken by Massil Benbouriche of the University ...
Research helps identify memory molecules
A newly discovered method of identifying the creation of proteins in the body could lead to new insights into how learning and memories are impaired in Alzheimer's disease.
A glassy look for manganites: Observing glass-like behavior in the electron-spins of PCMO crystals
(Phys.org) —Manganites – compounds of manganese oxides - show great promise as "go-to" materials for future electronic devices because of their ability to instantly switch from an electrical insulator ...
Optical components made of multiresponsive microgels
"Intelligent" materials that can respond to external stimuli are high on the wish lists of many scientists because of their possible usefulness in various applications from sensors to microrobotics. Canadian ...
Talking plants… science fiction?
Science is becoming closer emulating the fiction of the Avatar movie, by deciphering plants' electrical signals to devise new holistic environmental biosensors.
Giving birth to new insights into brain development and disease
Each one of us is the complex product of nature and nurture, genes and environment. They combine in a myriad of complex ways during embryonic and postnatal development to sculpt our brains and bodies.
Made to order at the synapse: Dynamics of protein synthesis at neuron tip
Protein synthesis in the extensions of nerve cells, called dendrites, underlies long-term memory formation in the brain, among other functions. "Thousands of messenger RNAs reside in dendrites, yet the dynamics ...
Whale mass stranding attributed to sonar mapping for first time
An independent scientific review panel has concluded that the mass stranding of approximately 100 melon-headed whales in the Loza Lagoon system in northwest Madagascar in 2008 was primarily triggered by acoustic ...
A new gene-expression mechanism is a minor thing of major importance
A rare, small RNA turns a gene-splicing machine into a switch that controls the expression of hundreds of human genes. Howard Hughes Medical Institute Investigator and professor of Biochemistry Gideon Dreyfuss, ...
Chemists design 'smart' nanoparticles to improve drug delivery, DNA self-assembly
A team of chemists in SU's College of Arts and Scientists has used a temperature-sensitive polymer to regulate DNA interactions in both a DNA-mediated assembly system and a DNA-encoded drug-delivery system.
Improving dogs' ability to detect explosives
Training of dogs to recognise explosives could be quicker and more effective following research by animal behaviour experts.
