The Conservative Party of Canada supports a 3 year prohibition on embryonic stem cell research.

They claim adult stems cells are more promising, so let's look at their claims.

#cdnpoli #elxn43 #NeverScheer #stemcells #research #science
The Ford Government has already cut funding for stem cell research.

"Scientist working on treatment of premature babies calls move 'extremely short-sighted and uninformed'"…
What are embryonic stem cells?
"Embryonic stem cells exist only at the earliest stages of embryonic development and are capable of making any cell type in the body."

1/ for what it’s worth, I don’t think being nice is strictly about pleasing others and being courteous. For me, it’s also about professionalism, easy collaboration, and inviting challenge. In fact, that last one might be the most important, particularly with #Science...
2/ I want to be receptive on every counter idea to my own. This is why invest so much time speaking to those with opposing views. I want to understand where they’re coming from and why. Many of my strongest opinions came from trying to defend its opposite unsuccessfully...
3/ And I’m certainly not perfect at this, I always feel like I could do a lot better.

Sometimes a friendly debate goes south and I spend the rest of the day thinking about what I could do or say differently to keep that from happening in the same way again.

Today in history: a massive nucleat explosion sends the Moon hurtling into space!

Well that was the premise of #Space1999. Let's take a look at some of the many impossible questions the series threw up... #FridayFeeling
In #Space1999 Moonbase Alpha is a 4km wide settlement in the Plato moon crater. It's both a research centre and a monitoring station for the vast amounts of nuclear waste Earth has dumped on the Moon.

Sounds like fun...
But that's the problem with setting sci-fi on the Moon: nothing tends to happen. Sure there's filing to do, computers to monitor, occasional meteors etc, but where's the action?

There's literally no atmosphere.

Africa generates less than 1% of world’s research.

Africa has 79 scientists per million compared to Brazil (656), Chile (428) & United States (4,500).

South Africa’s research foundation and Tunisia’s science ministry are the biggest funders of #science #research in Africa. /1
Woeful Africa:
1. 15% of the world’s population
2. 25% of the global burden of disease
3. 1% of global investment in R&D
4. 0.1% of the world’s patents

Scientists trained in Africa most likely work elsewhere due to lack of infrastructure and resources. /2

More than 80% of patents filled in Nigeria are by foreign entities. /3

So frustrating to #know the answer to the question of how to formulate that #TheoryOfEverything #scientists say is the biggest unsolved problem in #physics, yet they don't even want to look at it:…

Wave-particle duality a #mystery?
What I've found is rather astonishing:

The #mathematics used by #Maxwell are inconsistent.

He left the magnetic vector potential field [A] undefined and decoupled from the #medium thus creating #MaxwellsHole, which introduced an unwarrented #gauge #freedom in the model...
It is this #gauge #freedom thst led to the #hack known as #Quantum #Madness.

Really, it doesn't take a PhD to figure out that when you believe particles can exist at two places at the same time, you have a mental problem.…

Spending my day watching PragerU videos, and honestly, my brain is going to turn to pudding trying to wrap my head around these ridiculous leaps in logic
People don't idolize Ginsburg because they think she was the first woman on the court. JFC. What the hell kind of premise is this video based on?
Highly recommend Prager Remixes

Comment réparer la science ??? 🤔🤔

Cette vidéo mérite bien plus de 1730 vues (même si le son est un peu pourri).

Le pré-enregistrement : consiste pour les chercheurs à dire à un journal AVANT de commencer leur étude le but de leur étude et les méthodes / statistiques qu’ils vont utiliser.

Si le journal l’accepte, il s’engage à publier l’étude *quel que soit son résultat*, positif ou nul
Ça permet que les chercheurs ne soient plus incités à rendre leur étude aussi sexy que possible pour qu’elle soit publiée, et ça permet que les journaux arrêtent de ne publier que les résultats positifs (qui trouvent un effet, confirmant l’hypothèse du chercheur)

(Thread) A scientist’s view of the urgent need for @GavinNewsom to sign SB#1, written by @sentoniatkins.

Like every scientist concerned with preventing #extinction of #SFBay’s fish species, I want #endangeredspecies management to use only the best available science. 1/
@GavinNewsom @SenToniAtkins I supported then-Secretary @sallyjewell's call to review #endangeredspeciesact safeguards for the Bay’s imperiled fish species. Those reviews were necessary bc endangered fish continued to decline; Jewell wrote that she expected the review to lead to increased protections. 2/

Still think #BigOil is the answer? Consider this:

Before 1886, people travelled via horse and buggy.

#auto #car #oil #fossilfuels #cdnpoli #elxn43 #technology #RenewableEnergy #CleanEnergy #ClimateChange #ClimateEmergency
In 1858, the refining of #CrudeOil crude oil allowed for larger-scale processing & helped spur the #gas gas engine automobile (this is the first - 1886).

#auto #car #oil #fossilfuels #cdnpoli #elxn43 #technology #RenewableEnergy #CleanEnergy #ClimateChange #ClimateEmergency
The Model T, produced by @Ford, was the first mass produced vehicle, but not the first auto.

Innovation led to bigger, enclosed cars.

Many in community are looking for answers to the questions about the #science of #GeneticModification (GM). To help more people understand the evidence, today we are publishing a #Q&A that tackles some of the big questions. #auspol
Research by the Office of the Gene Technology Regulator (OGTR) has found knowledge about what foods in Australia are genetically modified is generally poor. A simple google search also demonstrates just how much conflicting & inaccurate information there is out there on GM.
Questions covered in the booklet include: What is GM? Are GM products safe? Where do we encounter GM products? The booklet draws on the knowledge & expertise of our Fellows and the Australian science community. Read the Q&A here:…

In 2019, a candidate for President declares that there are “at least three genders.” Can you point to the third gender in dogs? Birds? Horses? Whales? Even science says no👇
“There only two types of gametes (sperm- and egg cells), two types of sex steroids, (androgens and estrogens in vertebrates, and two types of ecdysteroids in insects).” Male & female. #Science #Facts
Scientists ascribe “gender role” confusion to “poorly understood cognitive memory system in which electrical phenomena and its association with the plasma membrane membrane-cytoskeletal complex of cells play a major role (learning, imitation and imprinting).“

A better alternative to "progress studies"

While I appreciate the importance of understanding & facilitating progress, I was underwhelmed by this proposal for a new scientific discipline.

I'd like to propose a better alternative....

#innovation #science #education

A while back, I put together a sampling of big challenges we face & a way to measure magnitude.…

But BIG problems demand big innovative solutions.

Unfortunately, the capabilities we need are scattered across disciplines & institutions.

What I propose is a global, cross-disciplinary strikeforce for each problem we face.

This model would truly meld purpose, education & action into a cohesive whole.

It would eliminate the need for yet another scientific discipline, while truly accelerating human progress.

Thursday thoughts on #risk assessment tools, roughly paraphrased from Janus & Prentky, 2003. "Like any tool of science, actuarial risk assessment can be used for good or ill." Used well, it can make decision-making more transparent.
Used poorly, ARA can have unintended consequences, including justification for "increasingly aggressive and expansive preventive detention #laws." Janus and Prentky "urge caution and mindfulness in using ARA."
In other words, we should consider not only the #science, but also the effects of relying on ARA. The accuracy of these tools does not address underlying concerns about legal paradigms that promote incapacitation based on group-based risk #Statistics. #cjreform

So excited that the paper that is the culmination of my #PhD came out in @ScienceTM today! As the COVER story! Can't wait to share this 6-yr labor of love with the world. Here are some of the main takeaways from the paper:

#BigDay #HealthTech #PortableMRI #HydrationSensor
MRI is a powerful diagnostic tool but it is too expensive ($1.5M) and time-consuming (10-60min) to use on a regular basis. We developed a portable NMR sensor that can harness the diagnostic power of quantitative MRI at a fraction of the time (<1min) and cost ($1k).
It is not necessary to generate images in order to take quantitative magnetic resonance (relaxometry) measurements. Removing the need to generates images makes the hardware simpler, smaller, and cheaper.

I wrote about this for the @MIT_alumni blog:…

Irish-born Oliver Byrne (1810-1880) was an innovator in mathematics education, particularly in the teaching of geometry.
His most well known book was his colorful version of ‘Euclid’s Elements’, published in 1847.… #science
Nearly a century before Mondrian made geometrical red, yellow, and blue lines famous, mathematician Oliver Byrne employed the color scheme for the figures and diagrams in his most unusual 1847 edition of Euclid's Elements.…
Byrne faced physical and financial hardship and ridicule from his contemporaries for his mathematical and pedagogical innovations. He also published How to Measure the Earth with the Assistance of Railroads (1838). #maths #histsci…

HOLY COW FOLKS, I am so excited to tell you the play-by-play of my first flight on @SOFIAtelescope and how FREAKIN COOL it was:
@SOFIAtelescope (telescope on airplane) is currently flying out of Christchurch, New Zealand for its “southern deployment.” It usually flies out of Palmdale, CA. They come down here to optimize time during northern hemisphere summer/Southern Hemisphere winter (long, cool nights).
Also some celestial targets are only observable from much farther south than round trip flights from/to California.

Pourquoi, en tant que chercheur, je ne signerai pas la tribune #NoFakeScience.
#recherche #science
Je suis ingénieur agronome et maintenant chercheur en écologie, je me sens bien évidemment au cœur de controverses, comme celles du #glyphosate ou des #OGM. en ce qui concerne le #changementclimatique, mes recherches ont aussi pour objet de décarboner les pratiques agricoles.
Il est évident que l'information scientifique et sa discussion dans les médias généralistes posent problème, notamment sur ces sujets. Les débats sont tendus et bien souvent chacun ne cherche qu'à défendre à tout prix sa posture.
