Neonicotinoids and why they need to stay banned 🐝

#SciComm #ScienceTwitter #SaveTheBees #ClimateEmergency #ClimateCrisis

 Neonicotinoids were banned by the EU in 2018 following multiple scientific studies which proved their severe detrimental impact on pollinators. Effects from neonics include reduced immune function, reduced foraging capabilities, and impaired cognition in bees.
The government has approved neonics for emergency use as a seed treatment on sugar beet. Yields have been impacted by beet yellows, transmitted by aphids. They argue that, because sugar beet does not flower and will not attract pollinators, the risk from neonics is acceptable.
Since the ban on neonics in 2018, the infection rate of beet yellows has increased year on year. Aphid populations have been proliferating due to mild winters, with no agrochemicals to solve the problem.

Sounds like a good case for neonics, right?
But this is the start of a vicious cycle. Climate change isn't going away. Winters will continue to get milder, resulting in the need for more and more pesticides to combat growing pest problems. Inevitably, this won't be the last time neonics are authorised for emergency use.
Although the use of neonics will be carefully controlled, the risk to wildlife is too high. Even if we discount bees, there are birds, small mammals, and other invertebrates in the soil and water that will inevitably suffer the effects of dangerous chemical run off.
Furthermore, although sugar beet does not flower and therefore won't attract bees, any surrounding flowering vegetation may contain harmful pesticide.
The government proposes to counter this with the use of herbicides on surrounding flowering 'weeds'. However, not only does this remove a food source for many species, but it adds yet more harmful chemicals into the ecosystem.
Finally, the government recently announced measures to
reduce consumption of sugary products from 2022. In the UK, we use 100,000 hectares of prime arable land to grow sugar. Not only is this crop terrible for our already damaged soil, but it is terrible for us!
Most UK adults consume at least double our recommended daily allowance of sugar, and more people than ever have diabetes.

If the government is serious about reducing the amount of sugar we eat, why are they risking the stability of our ecosystems to save it?

Dear colleagues,
It was with the greatest astonishment, deepest concern, and indeed bewilderment, that I took note of the "7th ad hoc statement" from the National Academy of Sciences Leopoldina on December 8th, 2020.
In my opinion, this paper is not worthy of an honest, critical-

weighing science oriented towards the service and well-being of man. I do not have any medical expertise. However, as a scientist committed to nothing but the pure truth, I take the liberty of speaking up. I feel very alarmed by several points:

1. On November 27, 2020, a group of 22 internationally recognized experts presented the following report on the PCR test, the linchpin of the "pandemic", for the Eurosurveillance magazine:

"External peer review of the RTPCR test to detect SARS-CoV-2 reveals 10 major scientific flaws at the molecular and methodological level: consequences for false positive results". Quote: "This highly questions the scientific validity of the test".

This report is mandated by Congress and focused on the impacts of climate change in the U.S.

Basically: This is what our best scientists think will happen to us as a result of the actions our government is (not) taking to address the most important problem in human history.

300 experts in 13 federal agencies volunteered their time to make sure you have this information.

Please share it widely.

“Climate change is projected to significantly affect human health, the economy, and the environment in the United

To expand on that finding:

Recently I learned something about DNA that blew my mind, and in this thread, I'll attempt to blow your mind as well. Behold: Chargaff's 2nd Parity Rule for DNA N-Grams.
If you are into cryptography or reverse engineering, you should love this.
Thread:


DNA consists of four different 'bases', A, C, G and T. These bases have specific meaning within our biology. Specifically, within the 'coding part' of a gene, a triplet of bases encodes for an amino acid


Most DNA is stored redundantly, in two connected strands. Wherever there is an A on one strand, you'll find a T on the other one. And similarly for C and G:

T G T C A G T
A C A G T C A

(note how the other strand is upside down - this matters!)


If you take all the DNA of an organism (both strands), you will find equal numbers of A's and T's, as well as equal numbers of C's and G's. This is true by definition.
This is called Chargaff's 1st parity rule.
https://t.co/jD4cMt0PJ0


Strangely enough, this rule also holds per strand! So even if you take away the redundancy, there are 99% equal numbers of A/T and C/G * on each strand *. And we don't really know why.
This is called Chargaff's 2nd parity rule.

Get a cup of coffee.

In this thread, I'll help you understand the basics of Binomial Thinking.

The future is always uncertain. There are many different ways it can unfold -- some more likely than others. Binomial thinking helps us embrace this view.


2/

The S&P 500 index is at ~3768 today.

Suppose we want to predict where it will be 10 years from now.

Historically, we know that this index has returned ~10% per year.

If we simply extrapolate this, we get an estimate of ~9773 for the index 10 years from now:


3/

What we just did is called a "point estimate" -- a prediction about the future that's a single number (9773).

But of course, we know the future is uncertain. It's impossible to predict it so precisely.

So, there's a sense of *false precision* in point estimates like this.

4/

To emphasize the uncertainty inherent in such predictions, a better approach is to predict a *range* of values rather than a single number.

For example, we may say the index will return somewhere in the *range* of 8% to 12% (instead of a fixed 10%) per year.

5/

10 years from now, this implies an index value in the *range* [8135, 11703]:

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.

Trump is a Russian asset, a mob money launderer installed by his mob whoremasters to sow chaos and weaken the US & our allies.

EVERY SINGLE THING HE’S DONE since taking office is to achieve those purposes—that and to enrich himself personally.

[THREAD]


1/ His entire family is part of this. Melania is a fucking crook. Ivanka is a fucking crook. Junior and Gums are fucking crooks. They will all die in prison, except for Kushner, who, if he really *did* trade US intel for money, should be executed for espionage.

2/ Why do you think Trump installs uniquely corrupt & awful people to Cabinet positions? Pruitt, Zinke, Betsy, Rex/Pompeo, Wilbur "Melting Nazi Face" Ross. They are not there to serve us. They are not there to drain the swamp. They are there to BURN THE REPUBLIC DOWN.

3/ Trump steals. He takes taxpayer money—your money and mine—and lines his pockets with it. He exploits his office to make himself richer. This is all he cares about. Why are Republican citizens, you “fiscal conservatives,” not more angry about this? Riddle me THAT, #MAGA.

4/ Matt Whitaker, the human dildo and “acting AG,” was illegally installed to throw a monkey wrench in the Mueller investigation. That’s why they won’t release his financials. He’s fucking bought and sold. He’s going to prison for obstruction.

Some people really benefit from hearing advice that everyone knows, for the same reason we keep schools open despite every subject in them having been taught before.

In that spirit, here's some quick Things Many People Find Too Obvious To Have Told You Already.

Your idea is not valuable, at all. All value is in the execution. You think you are an exception; you are not. You should not insist on an NDA to talk about it; nobody serious will engage in contract review over an idea, and this will mark you as clueless.

Technologists tend to severely underestimate the difficulty and expense of creating software, especially at companies which do not have fully staffed industry leading engineering teams ("because software is so easy there, amirite guys?")

Charge more. Charge more still. Go on.

The press is a lossy and biased compression of events in the actual world, and is singularly consumed with its own rituals, status games, and incentives. The news necessarily fails to capture almost everything which happened yesterday. What it says is important usually isn't.

Companies find it incredibly hard to reliably staff positions with hard-working generalists who operate autonomously and have high risk tolerances. This is not the modal employee, including at places which are justifiably proud of the skill/diligence/etc of their employees.

Some quick thoughts on Sam Gyimah's resignation after conversations with various Conservative MPs: 1) the chances of a second referendum are a lot higher than I thought:

2) At this point, if you are a young and ambitious Tory MP it is now so overwhelmingly in your interest to vote against the withdrawal agreement. V v hard to see how Julian Smith can cap rebellion at under 100:

3) Really just to reiterate 1) Gyimah is the kind of "No, never gonna rebel" vaguely pro-EU Tory you'd need to get on side to outweigh Labour Leavers and Real Concerners.

Beautiful story of Shri Krishna, Mata Rukmini & Satyabhama which teaches the importance of Bhakthi.
Devotion is important than anything.
#bhakthi
🕉
Satyabhama, royal princess was very proud of herself. Rukmini was very humble, her devotion was pure to Shri Krishna.


One day, Rishi Narada( Kalahapriya) arrived in Dwaraka and met Sathyabhama. In between the conversation he hinted that Krishna exhibits affection more to Rukmini than her. Worried Sathyabhama asked what can should be done to gain Krishna's undivided attention.
@SriramKannan77


Narada asked Satyabhama to make a vow, that she will hand over Krishna to him as a slave, if she cannot trade wealth equivalent to Krishna's weight. Narada thus convinces Sathyabhama that Krishna will admire her for sacrificing all her wealth for him.


Sathyabhama was sure that she have enough wealth to balance Krishna.

She went to Krishna and told about her vow to Narada. Krishna patiently listened to her and accepted the challenge. Satyabhama arranged to bring large scales to weigh and brought all her precious jewels.


Krishna patiently sat on one plate of the Scales (tula). Sathyabhama started piling up the gold, jewels on the other plate. She kept adding more and more wealth, but the pan with Krishna did not even budge. Even after keeping all her jewels the scale did not move a little
