❌ The Bite (Injection):
When a snake bites, it injects venom directly into the muscle tissue or bloodstream. It completely bypasses the body's natural defenses, allowing the toxins to travel straight to vital organs, shut down the nervous system, or destroy blood cells almost instantly.

✅ The Meal (Ingestion):
Snake venom is made up of complex proteins and enzymes. When an animal eats the snake, its highly acidic stomach juices and digestive enzymes (like pepsin) immediately go to work. They break the toxic proteins down into harmless amino acids, digesting it just like ordinary meat. As long as there are no open wounds or ulcers in the mouth or stomach, the venom is completely neutralized before it ever touches the bloodstream.

A venomous snake bites a wild animal, and it dies. But when the animal predates the snake and eats it, the animal will not die. 😀 Interesting biology.👇🏽

@anshulkundaje “entirely by AI” - not its not👀

@c5rcorp But still, only humans are executing the tasks, right? How is it advancing? It's basically helping me read protocols.

Singapore teachers are generally considered among the better-paid teachers globally**, especially when adjusted for the country's high standards for teacher recruitment and career progression.

Some indicators:

- In a recent **OECD TALIS 2024** survey, **55% of Singapore teachers reported satisfaction with their salaries**, compared with an **OECD average of 39%**. Teachers in Singapore are also far more likely to feel that teachers are valued in society (71% versus an OECD average of 22%). [1](https://t.co/VZ8LDwKfJr)
- Singapore's Ministry of Education (MOE) offers structured salary progression, annual increments, bonuses, and clear leadership and specialist tracks. Published salary guides indicate that beginning teachers can earn roughly **S$42,000 to S$52,000 annually**, with experienced teachers, department heads, and principals earning substantially more. [3](https://t.co/yW3OjdEk6M)[4](https://t.co/TyDSYubrEr)

Compared with other countries:
- Singapore teachers are typically paid **more than teachers in many Asian countries** such as India, Malaysia, Thailand, and Indonesia.
- Their pay is generally **competitive with teachers in Australia, Canada, and the UK**, particularly when career advancement and bonuses are considered.
- A few countries, notably **Luxembourg, Germany, and some Nordic nations**, still offer higher teacher salaries. [5](https://t.co/i4YbpNLqY7)

What is particularly notable is that Singapore combines:
1. Competitive salaries,
2. Strong professional respect,
3. Extensive training,
4. Clear promotion pathways,

which is why teaching remains an attractive profession there.

For someone coming from India, a Singapore school teacher would usually enjoy a significantly higher salary package and stronger institutional support than most teachers in Indian schools.

Claude has discovered a previously unknown enzyme system hidden in the DNA of bacteriophages. Beside the enzyme’s gene sits a long array of repeating DNA—a structure that looks somewhat similar to CRISPR.

We don’t yet understand what this system does, but only a handful of known systems share its features, and all of them are able to cut, copy, and paste DNA. Historically, the discovery of such programmable systems has helped revolutionize medicine. CRISPR, for instance, is now the foundation of genetic medicines. But it will take much more work to learn what this system does, and whether it can be put to similar use.

Singapore’s probably the only country in the world that takes racial harmony so seriously

With the recent Air India investment by SIA that caused some old school Singaporeans to use it as an excuse to be racist against indians, Singapore moved quickly to enact this bill

What it enables is basically allowing officials to convict anyone that tries to stir racial tension

Good stuff

@sundar_s1955 Happy Ganesh Chaturti🙏🏽🪔

@Vinamralongani @SGinIndia And if you are resident, you don’t even need passport. Just Face ID…💥🇸🇬

[Rayees Ahamed @RAYEESAHAMED]

They haven’t found a way to fix city roads yet come up with such stupid ideas with no real outcome.

If you forget your phone at home, its jackpot day for traffic police to fine you🤦🏽

🚨 Tamil Nadu had stopped issuing physical copies of driving licences (DLs) and registration certificates (RCs).

So very true
We need to live and enjoy the present that's why its called present a gift!!

Bro, just non-sense. Listed traits have nothing to do with genetics😄. All these born after the era of capitalism-driven economy, where we defined success by these traits.

For evolution & genetics, there is only one trait needs to be successful. “Survival-of-the-fittest” that is acheived by ability to reproduce and adapt to new environment.

[Machiavelli Bot @UnmodernmanBot]

Success is largely genetic. You need to be born with a subset of pre-determined traits, in order to be successful by metrics of human performance:

- High Intelligent (Ability to solve complex problems)
- High conscientiousness (Ability to work long hours without tiring out)
- Low Agreeableness (Task prioritisation and defense against exploitation and manipulation)
- Low Neuroticism (Ability to deal with extreme amounts of stress)
- A sense of never ending restless (insatiable greed, i.e ambition)

I raised this several times. These trucks are straight from World War-2, absolutely unworthy to be on road. Its never got upgraded since indepedence, just a moving coffin waiting to kill someone everyday. We gave so much importance to cars from ABS to airbags, totally forgot this killing machines.

"I used to sit down and just let my mind drift. Most of the time a useless activity, but occasionally it would lead to something that was useful. That sort of dreamlike state was very important in my life."

Richard Robson tells us how he accesses a restful state-of-mind in which ideas flow in this episode of our podcast – Nobel Prize Conversations.

We also speak with Robson's co-laureates Omar Yaghi and Susumu Kitagawa about how they changed chemistry forever by letting their minds wander to unplanned places.

@BVSrinivasan I see now mostly videos in NPTEL, previously they used to have pdf notes for each subject. Do they have now? Can’t find those anymore. Any idea?

[Rayees Ahamed @RAYEESAHAMED]

Total nonsense.. Instead of accountability and fixing things, preaching that infrastructure building is quantum science, so world will never understand why India couldn’t build liveable cities. Countries poorer than us did it decades back. Ppl like you come with an article every week to justify the hellhole created by politicians. Be shameless for writing this..!

[News from Science @NewsfromScience]

Same relaxing sounds, different photo. This is what a Jurassic forest may have sounded like.

By combining exquisitely preserved fossil wings with experiments on living insects, computer simulations, and machine learning, scientists have re-created what they say is a partial Middle Jurassic soundscape.

If the reconstruction is correct, one of the insect calls would be the oldest known evidence of ultrasonic communication in animals—long before echolocating bats appeared.
