Sit up and smell the roses better
Before giving flowers or scattering rose petals on Valentines Day, make sure your significant other has already gotten out of bed. In a study published recently in the journal Chemical Senses, researchers at the Montreal Neurological Institute (MNI) at McGill University discovered that sensitivity to rose odour is greater in subjects that are sitting than in those lying down.
This research, conducted in the laboratory of Dr. Marilyn Jones-Gotman at the MNI, adds to previous studies indicating that lying down negatively affects other senses, such as hearing and spatial perception. "This was an important finding for us, as many of our studies involve test subjects lying in an imaging machine such as MRI or PET (positron emission tomography) scanners. If perceptual ratings differ depending on whether the subject is outside a scanner (and sitting up) or inside a scanner (and lying down), then reliable threshold measures or points of comparison will be difficult to obtain."

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
