The True Bugs

There are around 55,000 known species in Hemiptera (a super-Order containing the Homoptera and the Heteroptera). For the most part, the members of these groups are Paurometabolous but there are a few species in the Homoptera that have a pupae-like final juvenile stage (white flies are an example of this, family Aleyrodidae, figure 5-1) that is somewhat transitionary in the evolution of the holometabola. Hemiptera may or may not have wings as adults, and some (like the aphids, family Aphididae) can have adults in the same species both with (alate) and without wings (apterous; figure 5-2). Other species always have wings as adults, like the Lygus bug (figure 5-3) in the Miridae family, and some species never have wings, like the Human parasite Cimex lectularius, the bed bug (figure 5-4).

Hemiptera occupy a wide range of ecological niches and have very different life history strategies within the group, but a few characteristics make them easily distinguishable from the other orders. The Hemiptera are most frequently confused with the Coleoptera, which have hardened forewings and chewing mouthparts. Though it may be difficult to see the difference in wing types, mouthparts types for Hemiptera are always piercing/sucking, evident by the long beak visible either in profile or the underside of the insect. The hardened forewings in the Coleoptera, the elytra, are completely hardened, which is not the case in any of the Hemiptera. The wings of the Homoptera order are soft and malleable when present, and held tent-like above the body at rest; the wings of the Heteroptera are half-elytra. For the latter group, only the proximal part of the wing is thickened (though not hardened as in Coleoptera, but more like the tegmina of grasshopper forewings). The distal end of each wing is membranous, though it may still have a dark color. When at rest, the wings fold over each other on the dorsum of the insect and the two sections overlapping often create an easily identified “X” pattern. The elytra of Coleoptera always meet along the medial line without overlapping.

Most of the Hemiptera are terrestrial and plant feeders, using their beak/stylet to feed on plant fluids the way mosquitoes feed on animal blood. There are some that can even transmit plant diseases as they move from plant to plant to feed (example: Tomato Leaf Curl Virus). Many of these plant feeding Hemiptera are therefore serious economical pests. There are a few members of the Hemiptera, primarily in the Heteroptera, that are economically important beneficial insects, acting as natural enemies of many other insects and arthropods, including other Hemiptera. A few examples of these are Assasin bugs (family Reduviidae, figure 5-5), and minute pirate bugs (family Anthocoridae, figure 5-6), and even one predaceous species of Stink Bug, family Pentatomidae (figure 5-7).

CS106B Programming Abstractions

Assignment 6 has now been released! This is the final assignment of the quarter and will be your opportunity to cap off a fast-paced quarter of learning by applying everything you've learned so far to implement one of the most powerful and prevalent real-world algorithms out there. This assignment will help you practice your tree manipulation skills, give you one last chance to flex your recursive muscles, and give you the experience of actually implementing the specifications of a well-known and widely-used algorithm. All in all, we hope you enjoy the assignment!

As for logistics, the assignment will be due on Wednesday, August 12 at 11:59pm PDT. Please note that this is a hard deadline. There will be no grace period for submission and we cannot accept any assignment submissions after the Wednesday night deadline. For these reasons, make sure to get started early! As a final note, we will be holding the A6 YEAH session tomorrow (Thursday, 8/6) at 7pm PDT. Zoom information for the session can be found on the Zoom details page. The session will also be recorded and posted on Canvas.

Check out the assignment page here – happy coding!

Due to an extended power outage, Trip's office hours that were scheduled for tomorrow morning from 7-9am PDT have been cancelled. We don't have plans to reschedule them at this time, but if they do get rescheduled to later in the week, we will send out another announcement with further details.

As mentioned in class today, we've shuffled around the lecture schedule for the coming week in order to be able to dedicate some class time to final project preparation during lecture tomorrow (Thursday). You can find the updated schedule here.

We will be dedicating all of tomorrow's scheduled lecture time to a final project collaboration/ discussion session. Lecture tomorrow is optional and will not be recorded since we won't be covering any new content. However, if you're able to make it, we recommend coming to chat with Kylie and me about your final project idea if you haven't done so yet. We'll also have topic-specific breakout rooms to allow you to meet and collaborate with other students working on similar project topics as well. We hope to see you there!

Week 4 Scan

The gestational sac first appears at about 4 weeks gestational age, and grows at a rate of about 1 mm a day through the 9th week of pregnancy.

It initially appears as a round, anechoic structure. In experienced hands, it may be detected as early as 30 days gestation by TVU.

At 4 weeks and 3 days, a tiny gestational sac becomes visible within the decidua.

While a gestational sac is sometimes seen as early as during the 4th week of gestation, it may not be seen until the end of the 5th week, when the serum hCG levels have risen to 2500 - 3500 mIU/mL.

At this early stage of pregnancy, the gestational sac already contains the yolk sac, embryonic disk, and amnion, but these structures are too small to be visualized by sonography.

In these early first trimester scans, when no structures are visible within the gestational sac, gestational age (GA) may be estimated from the sac diameter. A common method is to measure the mean sac diameter (MSD), add 30 to the sac size in millimeters, to give gestational age in days.

By the time the embryo becomes visible on ultrasound the sac diameter is no longer accurate in estimating gestational age. If cardiac activity can be detected but the embryo is not measurable, the GA is about 5.5 to 6.0 weeks.

5 Weeks Pregnant Ultrasound

Your week-5 embryo doesn't look like much more than a tadpole right now, but they’re already starting to form major organs (heart, stomach, liver and kidneys) and systems (digestive, circulatory and nervous).

If you don’t have a medical history that puts you at higher risk for pregnancy complications, you won’t likely have a 5 weeks pregnant ultrasound. Instead, you’ll just have to wait impatiently until your first prenatal visit, around week 8 or 9. We feel your pain!

When you do have your first ultrasound, the doctor or technician will measure baby from crown to rump and could adjust your due date based on baby’s size (which would change which week of pregnancy you’re in). You’ll have a slew of blood tests and urine tests to be sure you and baby are both doing fine. So while you’re totally amped up to see baby’s tiny fluttering heartbeat on the ultrasound screen, remind yourself you can wait a few weeks for the blood draws and peeing in a cup.

Is there a heartbeat at 5 weeks?

A heartbeat may be detectable between 5 and a half weeks and 6 weeks, but not always. That’s why, unless you have preexisting conditions or fertility concerns, most doctors wait until at least 8 weeks for your first ultrasound.


Reading through the Bible is a daunting task, no doubt. So, I set out to try to make it less intimidating. There are all kinds of scripture reading programs. If you follow a one year program and you fall behind, it is difficult to get caught up again. I tried to find a program that allowed for some wiggle room for you, the reader. But I couldn’t find one that appealed to me. I didn’t want us to follow a program just so we could say at the end that we read through the Bible. So, I developed a Scripture reading program that meets the following criteria:

Read 3 chapters a day 5 days a week Separate the Book of Psalms out from the rest of Scripture. So, to begin with, we will read from the Psalms. Harmonize the books of 2 Samuel, 1 & 2 Kings, 1 & 2 Chronicles. These books overlap in some areas. So, I made the attempt to put it all in chronological order as well as follow up certain time periods with the prophetic books written during those periods.

I know this plan won’t be perfect. But, I feel it will be a plan we all can follow together. In fact, this plan is better than just reading through the Bible in 2 years. Here is what we will actually do:

We will read through the Old Testament in 2 years (2 chapters a day) We will read through the New Testament 2 times in the same amount of time (1 chapter a day – the second year the reading is arranged by the date the book/letter was written. Interestingly, we begin 2020 with the Gospel of John and end 2021 with the Gospel of John.)

Notice that I did not begin with Genesis and Matthew. I started with Isaiah and John. Let’s begin seeing a clear picture of who Jesus is. AND, let’s devote ourselves to being in God’s Word and knowing Him.
