Researchers claim to have synthesized six additional elements in the second row, temporarily named ‘pentium’ through 'unnilium’.

An international team has succeeded in propagating a commercial hybrid rice strain as a clone through seeds with 95 percent efficiency. This could lower the cost of hybrid rice seed, making high-yielding, disease resistant rice strains available to low-income farmers worldwide. The work was published Dec. 27 in Nature Communications.

First-generation hybrids of crop plants often show higher performance than their parent strains, a phenomenon called hybrid vigor. But this does not persist if the hybrids are bred together for a second generation. So when farmers want to use high-performing hybrid plant varieties, they need to purchase new seed each season.

save this for your next academic year and finals, and it’ll save your grades and time.

1. whenever you read a paragraph with new content, close the book/look away and ask yourself: “what have i just learned?” explaining the concept to yourself right away and asking follow-up questions will change the way you retain new material forever.

2. at first, it’ll be daunting, and it’ll be pretty hard to actually bring yourself to do this. trust me, it’ll be worth it - as this is scientifically proven one of the most effective study techniques.

3. to try this out, set yourself a timer for how long you estimate learning a concept might take. now take away 20% from that estimate. you won’t be able to reach this goal with basic highlighting and re-reading techniques - but with active recall, you will.

4. once you’ve understood the concept, use spaced repetition systems like anki flashcards to force yourself to retrieve this information in a set period of time. this way, your brain will always be reminded of this concept before it could possibly forget it.

5. teach it to others as much as you can. as with the old wisdom “see one, do one, teach one”, one of the only guarantees you’ve really gotten something is when you can effectively teach it.

hope these are helpful for you!!

Today was day 4 of online classes and I'm already worried about falling behind!

Some notes on transition metal chemistry 🥼🧪

Oxidation

An oxidizing agent will have a large amount of oxygen

An oxidized compound will have more bonds to oxygen

More bonds to oxygen = loss of electrons

Reduction

A reducing agent will have a large amount of hydrogens

A reduced compound will have more bonds to hydrogen
