1. CRISPR came from basic research on bacteria.
2. Optogenetics started with a discovery in algae.
3. The GFP protein comes from jellyfish.
The biggest breakthroughs all trace to scientists follow their curiosity. This is one huge reason why we must keep funding basic research!

1/ Ever see a stunning bioinformatics figure and think:
“How on earth did they make that?”
Let’s break it down so you can recreate it.

how do professors time their lectures to end at exactly the right moment while still getting through all their slides, even with people asking questions and everything? seems like such an insane skill and honestly so hard

Your laptop can have 16GB RAM, Core i7 and still be a very bad purchase.
Before buying a laptop, take not of these 10 things:
1.🔹Go for SSD instead of HDD.
SSD makes the laptop significantly faster when booting, opening apps and transferring files. It also doesn't make the spinning noise HDDs make.
You can check by pressing Ctrl + Shift + Esc → then Performance → then Disk.
2.🔹Having a high RAM isn't enough.
A laptop with 16GB RAM and a weak or old processor can still perform poorly. So it's important to check the processor.
3.🔹 Focus more on the generation of the processor rather than just “Core i5” or “Core i7.”
Never assume an i7 is automatically better than an i5. A newer-generation i5 can outperform an older-generation i7, depending on the specific processors.
When you check the model number for most Intel Core processors, the number immediately after the hyphen tells you the generation.
For example:
i7-6500U = 6th Gen
i5-8250U = 8th Gen
i7-1165G7 = 11th Gen
i5-1235U = 12th Gen
i7-13700H = 13th Gen
4.🔹Don't ignore battery health, especially when buying a used laptop.
To check on a Windows laptop, open Command Prompt and type: powercfg /batteryreport
This will generate a battery report showing the design capacity and full charge capacity. The bigger the gap, the more the battery has degraded.
5.🔹Check the screen quality, not just the size.
A 15.6-inch screen isn't automatically better than a 14-inch one. To confirm, go to Settings → System → Display → Advanced display to check the resolution and refresh rate.
6.🔹Check whether the RAM and SSD can be upgraded.
Some newer laptops have their RAM already soldered, meaning you may not be able to increase it later.
7.🔹Check the ports you need.
USB-A, USB-C, HDMI, SD card slot, headphone jack and other ports can make a difference depending on what you use the laptop for.
8.🔹For a used laptop, test everything.
Don't just open the laptop, see that it boots.
Test the keyboard, trackpad, speakers, microphone, webcam, Wi-Fi, Bluetooth, charging port, USB ports, HDMI, hinges and screen.
Open a document and test every key. Play audio through the speakers. Connect to Wi-Fi and Bluetooth. Plug in a USB device and test the charger.
9.🔹Buy according to your needs.
For browsing, Microsoft Office, online classes and basic work, you don't necessarily need a high-end laptop.
For programming, heavy multitasking or professional software, you need a strong processor and sufficient RAM.
For video editing, 3D work and serious graphics work, you have to pay attention to the GPU, processor, RAM and display.
For gaming, don't focus on RAM alone. The dedicated GPU, processor, cooling system and display matter a lot.
Stay informed
And
Stay sharp! 🪒

5 Non-Negotiables for every business to Survive the Current Tax Environment
1. Tax Literacy - You have to be Tax literate
Whether you are a dentist, a plumber , an influencer, a contractor, SME owner or a political blogger , you must be tax literate.
You must understand:
-Your specific tax obligations (Income Tax, VAT, PAYE, TOT, Withholding Tax, etc.)
-Available tax regime options applicable to you ( TOT / Annual income Tax )
-Current tax law requirements and changes
-Compliance timelines (filing and payment deadlines)
- Compliance demands - eTIMS , records etc

If I were starting a PhD today, I would forget everything else in the first year and give 100% of my attention to the literature review, firming up my methodology, learning the relevant software, such as R and NVivo, and figuring out my data sources.

Last week I was in Nyandarua training milk farmers on eTIMS.
Their good customer, the dairy company that they sell milk to had organized the training for them.
When I was leaving, they gave me mutūngi mūgima wa iria ria kugagatia to carry back home.
Man listen, there is no milk in Kenya that can beat Nyandarua milk in terms of thickness. Not even girirando. Take that from me. I am the one telling you.
But after interacting with these farmers, this is my conclusion:
- If there is one group of people who genuinely need to understand eTIMS and its tax implications, it is our glorious farmers.
Why?
Many companies buying milk from farmers simply tell them. Kiwanuha tuletee eTIMS receipt ndio tukulipe pesa yako.
So the farmer runs to the cyber, gets the eTIMS receipt and complies.
But they do not understand what they are doing.
They have no clue what that eTIMS receipt means from a tax perspective.
At the end of the year, KRA can clearly see, through eTIMS, that you sold milk worth 1.2 million.
But because no one taught the farmer eTIMS implications, the farmer never collected eTIMS receipts from the agrovet when buying:
• Animal feeds
• Fertilizer.
• Seedlings.
• Farm chemicals.
• Animal drugs.
• Labour.
• Transport, etc
Their legit costs remain totally invisible. But their sales are fully visible to KRA.
Then trouble begins.
KRA sees the 1.2 million in sales. But sees almost zero deductible costs.
It is as if the milk fell from heaven.
So KRA retreats to Times Tower and treat the 1.2m as your farming profit.
Then demands about 30% income tax.
That is a whopping sh 300,000 tax.
But the farmer does not have that kind of money.
The money already went into animal feeds, workers, transport, veterinary costs, preparing the farm and keeping the cows producing milk.
The farmer is then left helpless before KRA.
This is why eTIMS education cannot stop at telling farmers how to issue receipts.
They need to understand the whole picture. That if your sales are being captured through eTIMS, you need to keep proper records and supporting eTIMS receipts for your legitimate expenses too.
If there is one group that deserves intensive training on eTIMS and its implications, it is our glorious farmers.
I'd also urge KRA to go to the village. To the farmers. To interact & educate them.
Explain practically what eTIMS means for them in Swahili or mother tongue.
It will make tax compliance easier and friendlier.
Please enlighten the farmers in your community.
They feed us all.
