science Stories below the fold: Monday edition

Lifestyle changes could lower need for high blood pressure medicine.

Duh. Hippocrates knew this. The problem? Given the choice between a pill and diet/exercize, most people prefer the pill.

Lolo jogged until he hit age 88, but he wouldn't give up his soy sauce/patis/salty Fiilipino dishes.

and of course, for severe high blood pressure, mere diet and exercize doesn't work.

For some of us, exercize is hell. (arthritis, fear of ridicule). My only exercize is to walk George the cat killing Labrador, but even then, I go with the cook for fear of falling/being pulled down by the dog).

well, it's not quite Megamaid, but someone is devising a boom to collect all that plastic trash in the oceans.

Left out of the article, of course, is that most of the trash in the oceans comes from Asia.

here, people throw trash on the street, and it goes into the open air ditches and then into the irrigation canals and rivers. Often it clogs the pipe type sewers if they aren't cleaned up, which is why Manila is always having floods.

now we have trash containers which helps: Except that the dogs and cats get into the containers and open the plastic bags where people have discarded their paper and plastic trash and food wastes.

DavidReneke has a report on Japan's Space elevator experiment.


“In theory, a space elevator is highly plausible,” Yoji Ishikawa, leader of the new experiment’s research team, told The Mainichi. “Space travel may become something popular in the future.” Obayashi Corp. estimates the total cost of a fully functional, first-generation space elevator to be 10 trillion yen (about $90 billion) — almost the same as that for the maglev train project connecting Tokyo and Osaka.
The Shizuoka University team’s space-elevator experiment comes on the heels of the International Space Elevator Consortium’s (ISEC) 2018 Space Elevator Conference in Seattle last month, where dedicated scientists, engineers and invited speakers gathered to discuss the latest developments, share new ideas and scrutinize new concepts for the novel space technology.

the Brazil museum fire destroyed a lot of precious artifacts, but the meteorite there survived.

I keep reading articles by the PC crowd that insist that science and math (and logic) are evil and needs to be reformed.

Latest (from pjmedia): Study Claims Gifted Math Classes Promote 'Academic Apartheid'


In his article — which relies heavily upon social justice math theory — Wells takes aim at what teachers call “academic tracking,” which is the practice of placing students in different math classes (such as pre-algebra or gifted classes) depending on test scores.
Under the tracking system, for example, a student who scores in the top 10 percent of his peers may be placed into a precalculus course. On the other hand, a student who scores in the lowest 10 percent may be placed into a remedial math class, or perhaps pre-algebra.
While this practice is fairly common in high school, it has come under criticism by teachers who worry about the impact of the practice on the lower performing students. The confidence of some students may suffer at the expense of others, especially minorities, it is argued.
of course, there is an alternative: devise a program to tutor the lower functioning students.




this is just a way for the PC to undermine western civilization by attacking logic/math/science. Or mean girls trying to put down we nerdy science gals (and of course, men).

on the other hand, some people just can't do math: Both CSLewis and Winston Churchill come to mind.

Powerline links to an article in Nature magazine that measured forests and found that no, they are not declining.

the problem here is illegal logging, that leads to mud filled rivers, floods, and landslides.

but in the NE USA, the farms have reverted back to forests in many areas. You could hike in the forests and come across foundations of lost houses and find apple trees etc. that marked where they were once farms.

bad news of the day: Vaccines for HIV, TB and malaria are probably not coming in the near future.

it's not just a first world problem: China's low birth rate problem

Probiotics are useless. the study was in healthy people.

But what about replacing the good bacteria killed  by antibiotics?
