No-till farming uses cover crops to conserve soil and suppress weeds but many vegetable producers haven't embraced it yet.
The reason is simple; small-seeded vegetable crops struggle to emerge through thick cover crop residues. A recent program sought to see how it might work better with string beans, a common staple of many dinners, and possessing larger seeds. In both Illinois and Washington, USDA-ARS agronomist Rick Boydston and University of Illinois ecologist Marty Williams grew vetch, rye, and a combination of the two cover crops before killing them with a roller-crimper—a machine that evenly flattens and crimps standing plant biomass—or with a combination of the roller-crimper and a burndown herbicide.
I would like to use this space to advertise a couple of blogs you might be interesting to know about. Many of you who erratically read this blog may probably have already bumped into those sites, but I figured that as the readership of a site varies continuously, there is always the need to do some periodic evangelization.
Never compare between only Blacks (B) and others for example, or only Caucasian Whites (CW) and B. One should consider at least three together instead of only two. For example, consider also the North East Asians (NEA). Why? Without considering NEA, B and CW are merely two different regions in whatever parameter space, say crime rates, and all interpretations are still on the table. But relative to B, NEA are almost invariably on the other side of the CW data points, at even higher intelligence, even less crime, even less sexual dimorphism/rape, even higher GDP, graduation rates, and so on.
There is no correct moral theory.
All morality is politics. People do not act on the basis of morality. Everybody
does everything they do for the most meaningful reason at the time. If an act
may be judged as moral, so much the better. But, if an act cannot be judged as
moral, and if it is meaningful enough to a person to do it, and if it seems
like a good idea at the time, then it will be done. Morality is just political
correctness masquerading as the right thing to do – at the time. However, the
social psychology of the individual will always weigh the political correctness
of an act against the meaningfulness of the act, and proceed accordingly. Yet, the
point is none of us do what we do because we want to be moral authorities.
Sitting has been branded the “
new smoking” for its supposed public health risks, especially for people with sit-down office jobs.
Over the past 15 years or so sitting has been linked with cancer, heart disease and diabetes and even
Every year, at about this time, the level of activity of physicists working in experimental collaborations at high-energy colliders and elsewhere increases dramatically. We are approaching the time of "winter conferences", so called in order to distinguish them from "summer conferences".
During winter conferences, which take place between mid-February and the end of March in La Thuile, Lake Louise, and other fashionable places close to ski resorts, experimentalists gather to show off their latest results. The same ritual repeats during the summer in a few more varied locations around the world.
Women who received a health scare in the form of a false positive result from a screening mammogram were more likely to delay or even forgo the next mammogram than women who had a correct negative result.
A false positive result from a screening mammogram often leads to emotional, physical, and economic stress, though false positives are an expected part of proper medical care. For this study, the authors obtained data for women who received mammography screening through a large health care organization with multiple facilities in the greater metropolitan Chicago area. Among the 741,150 screening mammograms from 261,767 women included in the analysis were 12.3 percent that yielded a false positive result; the remaining 87.7 percent yielded true negative results.
The Dead Sea scrolls used to be revered as holding some special insight, perhaps we were only now mature enough to understand it. More recently, it's clear these were errors and cast-offs that were given a proper burial, but have no real benefit.
To archaeologists, it's instead just science, another way to understand the past. A new cave has been found, though scientists didn't get their first, they were clearly looted in the middle of the 20th Century, but the scholars still suggest the cave should be numbered as Cave 12, along with the 11 caves previously known to have housed hidden Dead Sea scrolls, even though this one has no scrolls.
