<p class="wp-block-paragraph">Yesterday afternoon, I was practicing piano when I heard a large bang. &nbsp;Since we&#8217;re not that far from Fort Devens, loud bangs aren&#8217;t that unusual. &nbsp;Devens frequently has training sessions where they&#8217;re setting off grenades, mortars, and all sorts of other munitions, and it&#8217;s just part of the deal when living in this area. &nbsp;This sounded different though. &nbsp;There was a low-frequency component to it that didn&#8217;t sound normal to me. &nbsp;Normally, I&#8217;d investigate something like this further, but I was in the middle of practicing and assumed that whatever caused it wasn&#8217;t local, so it would be a waste of my time to find the source.</p>



<p class="wp-block-paragraph">Later on in the day, while glancing through Facebook posts, I discovered that others had also heard the bang.  In fact, people in most of eastern and central Massachusetts and parts of New Hampshire and Road Island had also heard it.  A bit later, the news reported that it had been determined to be a meteor that exploded over the ocean east of Cape Cod.  I searched for more information and came across footage posted by people, taken from security cameras and dash cams.  Most of the videos were pretty boring, just the sound of the bang and the sky lighting up,, but one taken from New York actually showed the meteor descending through the atmosphere, although I&#8217;m still not convinced this one is real.  Anyway, mystery solved and I moved on to other things.</p>



<p class="wp-block-paragraph">This afternoon, a thought occurred to me. &nbsp;We have security cameras,, and one faces east with a partial view of the sky. &nbsp;Perhaps I had recorded something. &nbsp;I wasn&#8217;t expecting much. &nbsp;The view of the sky was pretty limited, and it was unlikely the camera was pointed at a location that would actually show the meteor, but perhaps I could see the flash in the sky.</p>



<p class="wp-block-paragraph">I logged into the security camera server, opened the camera&#8217;s history page, and selected the time of the event, which, according to the news, was at 2:06 PM EDT on Saturday, May, 30, 2026. &nbsp;Surprisingly, I did capture something. &nbsp;Not much, but it still is a record of the event. &nbsp;The camera I was using is on the side of the house, facing east towards our backyard. &nbsp;At 2:06, there is clearly a flash, and when the video is slowed down, you can see the light strafing the chimney. &nbsp;It&#8217;s actually pretty amazing. &nbsp;It was an overcast day in our area, as you can see from the sky in the background, and the area to the right of the video is filled with rather tall trees, yet the flash was able to penetrate through and actually appear on the video.</p>



<p class="wp-block-paragraph">It&#8217;s possible that what I&#8217;m seeing is something completely different, but given the matching times, I&#8217;d be surprised if that is the case. &nbsp;So it looks like I caught evidence of the meteor explosion.</p>

										<content:encoded><![CDATA[<p>I found this pretty amazing. A beetle whose defense mechanism is the ability to shoot hot boiling liquid and gas at an attacker. The beetle produces the liquid using an exothermic reaction of hydrogen peroxide and peroxidase enzymes. The temperature of the expelled liquid is around 100C.</p>

										<content:encoded><![CDATA[<p>Every year there will be a story on the news about a lobster man that found a &#8220;rare blue lobster&#8221; and ends up donating it to science. I heard such a story this weekend and have a couple of thoughts about it:</p>
<p>1. If blue lobsters are so rare, how come every year there&#8217;s a story about one being found?<br />
2. What&#8217;s with the donating to science?</p>
<p>According to Wikipedia, &#8220;A genetic mutation causes a blue lobster to produce an excessive amount of a particular protein. The protein and a red carotenoid molecule known as astaxanthin combine to form a blue complex known as crustacyanin, giving the lobster its blue color.&#8221;</p>
<p>It seems to me the science is pretty well understood, so what&#8217;s the purpose of donating it to science? Do the scientists really use it for research?</p>
<p>I&#8217;m guessing a bunch of scientists were enjoying nice lobster rolls this weekend.</p>
