Gleanings of the Week Ending August 13, 2016

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Desalination could harm Texas bays – It is important to get intake and discharge points for desalination right to avoid adverse environmental impacts.

What’s changed in genetic since your high school biology – My high school biology was at the very end of the 1960s….a lot has happened since. I’ve taken some classes to update myself but it is always interesting to see a summary of the high points in articles like this.

Maintaining healthy forests takes more than planting trees – What about massive wildfires and invasive forest pests. A healthy forest is a diverse mix of young and old trees, dead trees, and openings. Forest scientists are realizing that homogenous and overgrown forests need to change. A follow-on post talked about technology for foresters in the field.

Humans Never Stopped Evolving – A discussion of more recent human traits.

Strange Minerals from Siberian Mine Are Unlike Anything Found in Nature – Naturally occurring metal-organic frameworks (MOFs)?

Toxic blue-green algae adapt to rising CO2 – This does not bode well for fresh water supplies as the CO2 levels rise.

Protein Packed Produce for Meatless Monday – Meat is not the only food with protein…think veggies too: peas, broccoli, mushrooms, Brussels sprouts, asparagus, artichokes, spinach, kale and cauliflower!

The Best Schools in the World Do This. Why don’t we? – An peek into a report from the National Conference of State Legislatures.

The Neanderthal in the Mirror – A short history of our understanding Neanderthal skeletons....seeing them as more and more ‘human’ over the past century.

PDF Quads (from National Geographic) – National Geographic as a web interface that allows anyone to find any USGS quad for downloading and printing!

Microphotography from the 1970s

I found some microphotos from the 1970s when I was scanning some old slides and prints. The first set is algae from my last year of high school. It was a new school and the microscopes were new too. My boyfriend (a year later he became my husband) was the one with the camera and he had an adaptor to attach the camera to the microscope. The color images did not turn out as well as I wanted – the lamp was not bright enough or the film was not fast enough to make the background as white as it looked to the eye and the greens did not stand out. Still you can see the spirals of the spirogyra. I had collected samples from streams near where I lived; in one case the filamentous algae were growing on a rusting sewing machine that someone had dumped in the water (the algae had picked up the rusty color too).

The black and white image was actually better although some of the filaments look battered.

Several years later, I was taking a mycology class and had slides from various kinds of cultures fungus spore structures. We evidently didn’t bother with color slides although I wish now that we had since the dye used was a very nice blue.

Of course, all was film during that time period. There was a time lag between taking pictures and finding out if they were any good and it was relatively expensive. I’m glad we made the effort and managed the expenses. But it also increases my appreciation of digital photography!

Gleanings of the Week Ending July 2, 2016

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

8 Ways to Protect your Eyes if you stare at Screens All Day – You probably have heard of most of these before….but how many do you actually include in your day to day screen time? I just recently got computer glasses…now wish I would have done it years ago.

The Rabies Vaccine Backstory – A little bit of medical history for the week.

Ten simple rules to use statistics effectively – The report is intended for the research community – but it seems like just about everyone needs to understand these. We are bombarded by statistics at every turn…and many times they are coming from outside our area of expertise; we have to make a conscious decision about how ‘real’ what they reveal might be.

Are your pipes made of lead? Here’s a quick way to find out – With Flint, Michigan’s problems with lead in their water supply being in the news, why not do a quick check to see if the pipe bringing water into your house are made of lead?

CDC to Track Algal Blooms – Evidently algal blooms have become enough of a health hazard to warrant this step.

4,200-year-old Egyptian Temple Discovered to have Remarkably Well Preserved Artwork – Images of the same temple from several photographers. One show half the ceiling cleaned…half still covered with soot. I wondered if the soot actually served to protect some of the pigment from being scoured by sand over the years.

Journey Through the Largest Cave in the World – It’s a cave discovered in 2009 in Vietnam. There are sinkholes that allow light into parts of the cave…a jungle inside the cave.

No association between ‘bad cholesterol’ and elderly deaths – Systematic review of studies of over 68,000 people…questions about the benefits of statin drug treatments for them. Older people with high level of a certain type of cholesterol (low-density lipoprotein) actually live as long, and often longer, than their peers with low levels of this same cholesterol. This implies that what is true for cholesterol for young and middle-aged people is not for older people!

A virtual field trip to the Giant’s Causeway, Northern Ireland and Siccar Point, Scotland – Some online geology!

Hubble Images of Jupiter’s “Northern Lights” are Amazing! – Something new to know about Jupiter – it has a much stronger magnetic field than Earth…and Aurora’s along with it.
