The draft human genome sequences have been published in Feb., 2001. Although the sequences are the marked milestone of the internationally conducted human genome project, they still need to be finished by removing ambiguous parts and by filling remained gaps. The currently available human draft sequences also have a limitation in their usage and reliability because they still are in the draft status. Nonetheless, the human genome holds an extraordinary trove of information about human development, physiology, medicine and evolution.

The “phase separation” is a current topics in the field of magnetoresistive manganites. This is the phenomenon that a homogeneous compound is separated into several electronic and magnetic regions at low temperatures. From a structural point of view, we try to clarify the phenomena and its interrelation with the in-sulator-metal transition. We further discuss the difference between the “phase separation” and the two-phase coexistence in a bi-alloy system.
On the other hand, an important order-parameter of strongly-correlated electron system is the charge density
n. Then, we expect a spontaneous fluctuation of
n (charge separation), analogously to the two-phase coexistence in a bi-alloy system. Based on the recent experimental results, we argue the possibility of the charge separation.

Most specific properties of excitons in mesoscopic semi conductor quantumdots are discrete density-of-states (DOS) and enhanced electron-hole and many-body correlations. Long-lived co herence, which is essentially due to the atom-like DOS, efficiently enhances coherent as well as multi-photon processes. Single-dot spectroscopy revealed a purely quantum mechanical effects: Because QDs can open not only one-photon absorption into the discrete exciton states but also multi-photon processes into the higher-order exciton states, one observes quantum mechanical interference effects among the possible optical transition pathways, giving light-induced transparency.

In geometrically frustrated spin systems based on the tri angular-like lattice, spin ordering is fairly suppressed and an exotic state tends to appear. What happens then, if charge degrees of free dom is added to such systems? In this article, new phenomena in pyrochlore R
2Mo
2O
7 (R is rare earth) and spinel AlV
2O
4, which arise from charge degrees of freedom with geometrical frustration, are reported and discussed.
