One mental health expert likens a student suicide to a bomb going off in the school. Those closest to the student are most directly affected, but the impact can impact the entire student body, even those who didn’t know the student well. It’s critical that schools respond in the correct way, both to help students and staff heal, and to prevent additional suicides. Schools have to walk a fine line between not glamorizing the death, but not ignoring it either. They need to provide opportunities for students and staff to grieve and receive counseling. We talk with mental health professionals about how schools should respond. The American Foundation for Suicide Prevention also has a comprehensive toolkit for schools to help them react quickly and appropriately. https://bit.ly/2pq1B3h

If you are in crisis, please call the National Suicide Prevention Lifeline 1-800-273-TALK (8255) or contact the Crisis Text Line: by texting TALK to 741741

Multivariable Calculus on Khan Academy: Think calculus. Then think algebra II and working with two variables in a single equation. Now generalize and combine these two mathematical concepts, and you begin to see some of what Multivariable calculus entails, only now include multi dimensional thinking. Typical concepts or operations may include: limits and continuity, partial differentiation, multiple integration, scalar functions, and fundamental theorem of calculus in multiple dimensions.

DeepSeek has released DeepSeek-R1, an open-source AI model that matches the performance of OpenAI's o1 in reasoning, math, and coding tasks. This model, under an MIT license, allows for free use, modification, and commercialization, significantly reducing costs by using pure reinforcement learning. DeepSeek-R1 has shown competitive or superior results in benchmarks like MMLU, Codeforces, and GPQA. The release has sparked discussions on the implications for AI regulation, the economic impact on proprietary models, and the potential for open-source AI to advance rapidly. It's now integrated into platforms like OpenRouter and available for public evaluation, highlighting its practical applications and community engagement.

What happens during metaphase?
In this video, I would like to talk about the stage of mitosis called metaphase.
Mitosis consists of four stages and I always remember mitosis using PMAT
For Prophase Metaphase Anaphase Telophase
During metaphase the sister chromatids align in the middle of the cell.

However for this to happen a couple of things need to happen during prophase
During prophase the chromatin condenses into x shaped chromosomes.
Each half of the x is a sister chromatid and identical copies of the DNA
The two sides of the x shaped chromosome are attached at the centromere.

During metaphase spindle fibers appear These fibers create something called the spindle apparatus.
It consists of spindle fibers, centrioles, and another fiber called aster fibers
In plants, the centrioles are missing.
These spindle apparatus move to the poles of the cell.
The spindle fibers attach to the centromeres of the sister chromatids at the kinetochore.
After the spindle fiber is attached at the kinetochore the sister chromatid is pulled along the spindle apparatus and eventually end up in the middle of the cell.

Metaphase is the shortest stage of mitosis but is important because it helps ensure that new cells have correct copies of the chromosomes.
Take a journey to the cell

Educational video for children to learn how it works and which parts of the body are related to the sense of touch, which allows us to detect, identify and distinguish among the properties of the objects and the world around us. Thanks to it, we can perceive temperature, forms or textures. Also thanks to it, we can perceive pain. The skin is the sense organ of touch, and it is divided into different layers: epidermis, dermis and hypodermis. In this video, children will discover what each layer is meant for and what is the overall function of the sense of touch. If we touch something hot, receptors and nerve endings in our skin collect the different sensations and send the information to the brain through the nerve endings. The brain will be in charge to recognize the shape of the object, its texture and of course its temperature. In addition, the video ends with some correct skincare recommendations.

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.
