Search for Time-Reversal Violation in the beta-Decay of Polarized 8Li Nuclei

The transverse polarization of electrons emitted in the beta-decay of polarized 8Li nuclei has been measured. For the time reversal violating triple correlation parameter we find R = (0.9 +- 2.2)x10^{-3}. This result is in agreement with the standard model and yields improved constraints on exotic tensor contributions to the weak interaction. It also provides a new limit on the mass of a possible scalar leptoquark, m_{LQ} > 560 GeV/c^2 (90% C.L.).Comment: Submitted to Physical Review Letters, 4 pages, 3 figures, uses revtex

Beneficial Effects of Probiotic and Food Borne Yeasts on Human Health

Besides being important in the fermentation of foods and beverages, yeasts have shown numerous beneficial effects on human health. Among these, probiotic effects are the most well known health effects including prevention and treatment of intestinal diseases and immunomodulatory effects. Other beneficial functions of yeasts are improvement of bioavailability of minerals through the hydrolysis of phytate, folate biofortification and detoxification of mycotoxins due to surface binding to the yeast cell wall
