Blossom blight of seed alfalfa (Medicago sativa L.), caused by fungal pathogens Botrytis cinerea Pers.:Fr. and Sclerotinia sclerotiorum (Lib.) de Bary, can contribute to significant yield declines in moist growing seasons. In a greenhouse study that examined the occurrence of pollen infection by B. cinerea, pollen infection was observed at very low levels (<1% of pollen infected) in suspension-inoculated treatments. When leafcutter bees (Megachile rotundata), hypothesized vectors of B. cinerea spores, were collected from seed alfalfa fields, the bees tested positive for B. cinerea but their pollen load did not. Frequency of bees carrying B. cinerea spores increased over the growing season, with 96-100% of bees from the final collections (~August 20) testing positive for B. cinerea. These patterns closely follow patterns of observed airborne B. cinerea spore concentrations as detected by a quantitative polymerase chain reaction (qPCR) assay using aerosol samples collected from seed alfalfa fields. A sensitive, species-specific primer and probe for S. sclerotiorum was designed for use in the same qPCR assay. Discharge of S. sclerotiorum in one field closely followed the discharge of B. cinerea spores, with several larger (>200 ascospores per day) discharge days observed beginning in mid-July and continuing to the end of August. In the other two fields surveyed, discharge of S. sclerotiorum was concentrated in one or two large events. It is concluded that pollen infection and transmission of blossom blight pathogens by leafcutter bees are not large contributors to the spread of blossom blight in southern Alberta. In addition, using qPCR to quantify airborne inoculum levels will likely be useful in developing a disease forecasting model for blossom blight of seed alfalfa.

Reich has reservations about volunteering to give preparticipation physicals to clear children for sports participation. There is no need for such examinations since children should be seeing a primary care physician anyway.

During the run on the bank scene, George Bailey – played by James Stewart – explains the nature of banking to the small town depositors in Bedford Falls. The rival bank in town (operated by villainous robber baron Mr. Potter) offers $.50 on the dollar to redeem shares in Bailey's failing Building & Loan. Today in the United States Bankruptcy Court for New Jersey, BlockFi's counsel described the company as the \"antithesis\" of FTX. Reading various court documents from both bankruptcies together, it appears from the First Day Declaration of John J. Ray, III (the new CEO of FTX) that FTX actually loaned BlockFi $250 million worth of FTT tokens, and not actual U.S. dollars.

If your home is broken into and cash is stolen, your homeowners insurance policy usually provides some relatively low limits of coverage. Imagine if 2 million shares of stock on the New York Stock Exchange, worth over a half-billion dollars, just evaporated off the exchange's floor on a random Thursday? Because the NYSE is just an exchange and is not a custodian. Coincover also provides coverage to individual traders and wallets, with a product designed to cover theft by various methods (hacking, security breach at the exchange, employee theft, etc.) and is backed by Lloyd's.
