the Parker Solar Probe made another daring pass, flying just 3.8 million miles from the Sun's surface. At its peak, the spacecraft traveled at nearly 430,000 mph — fast enough to get from Philadelphia to Washington, D.C., in just one second. During the pass, the probe's heat shield...
The data will be used for improving cloud modeling (including cloud microphysics´ schemes) in another part of the project. The main objective of the postdoctoral researcher will be to evaluate the strength of major land cover (coffee, Brachiaria spp., Eucalyptus and indigenous restoration ...
One group of bees watched another previously trained bee move the ball to the centre. A second group of bees observed the ball moving to the centre "by itself"(we actually used a magnet(磁铁)under the platform to move the ball). And a third group of bees did not receive any ...

but were judged inadequate for monitoring purposes because of the poor retention of oocysts within the column matrix at realistic flow rates. Another study tested a filter matrix dissolution method to recover Cryptosporidium oocysts from water. The average recovery rate observed was 70.5%. Aldom et...
