One of the now rare species of oysters in the Pacific Northwest is the Olympia oyster, Ostrea lurida, (Carpenter, 1864). While rare today, these are British Columbia’s only native oyster. 

Had you been dining on their brethren in the 1800s or earlier, it would have been this species you were consuming. Middens from Vancouver Island's norther tip to California are built from Ostrea lurida.

A Devonian bony fish mortality plate showing a lower shield of Zenaspis podolica (Lankester, 1869) from Lower Devonian deposits of Podolia, Ukraine.

While war rages on in the Ukraine, our hearts go out to those who live and work here contributing much to our understanding of Podolia, a historic region in Eastern Europe, located in the west-central and south-western parts of Ukraine, in northeastern Moldova. 

The Hallstatt Limestone is the world's richest Triassic ammonite unit, yielding specimens of more than 500 ammonite species.


Along with diversified cephalopod fauna  — orthoceratids, nautiloids, ammonoids — we also see gastropods, bivalves, especially the late Triassic pteriid bivalve Halobia (the halobiids), brachiopods, crinoids and a few corals. We also see a lovely selection of microfauna represented. 

Driftwood Canyon Provincial Park covers 23 hectares of the Bulkley River Valley, on the east side of Driftwood Creek, a tributary of the Bulkley River, 10 km northeast of the town of Smithers in northern British Columbia. 

About a month ago I was contacted by a colleague who invited me to write a piece on the topic of science outreach for an electronic journal (Ithaca). I was happy to accept, but when I later pondered on what I would have liked to write, I could not help thinking back at a piece on the power and limits of the use of analogies in the explanation of physics, which I wrote 12 years ago as a proceedings paper for a conference themed on physics outreach in Torino. It dawned on me that although 12 years had gone by, my understanding of what constitutes good techniques for engagement of the public and for effective communication of scientific concepts had not widened very significantly. 

Life may be detected in a single ice grain containing one bacterial cell or portions of a cell which means it could be found in the frozen sea spray from the moons orbiting Saturn or Jupiter.

Finding that will take is a mass spectrometer onboard a spacecraft, and that will happen when the Europa Clipper mission launches in October with the The SUrface Dust Analyzer.

The authors couldn't simulate grains of ice flying through space at 2 to 3 miles per second to hit an observational instrument so they used an experimental setup that sent a thin beam of liquid water into a vacuum, where it disintegrates into droplets. They then used a laser beam to excite the droplets and mass spectral analysis to mimic what instruments on the space probe will detect.

A recent study in mice suggests the the liver is key in a molecular link that may also cause humans with diabetes to develop Alzheimer’s disease.

Unlike type 1 diabetes, type 2 diabetes is overwhelmingly in obese people so if the findings in mice ever apply to humans the prevention of Alzheimer’s disease in such people could be avoiding it in the first place.

Given that most adult women did not have access to the HPV vaccine in youth, the clinical burden of cervical cancer in the United States has not yet declined.  

Women still get tested and a few thousand still die each year. The authors believe that the increase in saved life-years has not occurred because taxpayers haven't yet spent enough.

Risk factors like salt and sugar intake and high blood pressure for heart attacks and disease need constant rethink if they are going to be more than folk wisdom.

Low-salt and sugar-free have too many vested interests to get critical thinking on how valid population-level statistics are for individuals, and 'high' blood pressure rarely gets questions about how reliable the correlation was that picked 130/85 mmHg (millimeters of mercury) as high blood pressure for everyone. Thosa blood pressure numbers are the clunkily-named systolic on top over the diastolic below. The top is the pressure in arteries as the heart beats while the bottom is the pressure at rest.(1)

If humans in space are happening any time soon, it will be despite government involvement rather than because of it. NASA couldn't even build a telescope without going 25 years and 1,000 percent over budget. By the time all cultural parties pick away at a manned space program, it will be so expensive and time-costly it won't be worthwhile, and the private sector will throw all that baggage out and just do it.

The James Webb Space Telescope program showed NASA is incapable of doing Big Engineering now, but they can put cute robots on other planets, and fund smaller projects, like how we might grow plants. Early results for how monitors that plants can wear and will stretch as plants grow are due to a NASA grant, and that is a very good thing.
