If they are working on sponsored or funded research, they usually wont share their work until after the work is reported and published.'Grey lit funding" as consultants usually work within, is very competitive also . Consider a mining exploration company being hired by a major oil company to find oil reserves. All the science and engineering consultants usually work on a confidentiality "non disclosure" basis.
Most of what we read in science news is usually several years old. Even stuff as "Kid friendly" as finding fossils. For example, in 2006 a team of scientists reported the finding of a new fossil which was half fish/half tetrapod. When the science work was reported in the popular literature, it was already 3 years old and all the peer review hoopla was past.
