What (Or Who) Is Sending Fast Radio Bursts?

Fast Radio Bursts are exactly what they sound like. They’re highly energetic bursts of radio waves that last mere milliseconds. And they’re totally random.

Because of how elusive they are, scientists are still trying to explain this weird phenomena. But thanks to new telescopes like CHIME in Canada, we’re getting closer to the solution to this science mystery.

Are We On The Verge Of A Post-Antibiotic World?

Ever since antibiotics were invented, we’ve known that they come with an expiration date. That’s because bacteria, like everything on Earth, evolve. And they are quickly evolving a resistance to the thing protecting us from them.

Alexander Fleming first discovered penicillin by accident in 1928, and ever since then we’ve been dealing with various types of antibiotic resistance. But it’s the recent trend of pan-resistant bacteria – bacteria that’s resistant to all forms of antibiotics.

Multi-drug resistant forms of pneumonia, salmonella, tuberculosis, and even gonorrhea have surfaced over the last 5 years. And researchers are scrambling to figure out how we’re going to protect ourselves in the age of superbugs.

How Atomic Bombs Help Catch Art Forgeries

Art forgery is a multi-million dollar business, one that museums and appraisers are constantly battling. But there is one technique they’ve found to foil forgers that’s near foolproof – and it involves atomic bombs.

Wolfgang Beltracchi is an artist who got his start as a forger of classic masters like Picasso, Van Gogh, and others. But he and those in his business found a foil in Peggy Guggenheim, Dr. Elena Basner, and a cadre of scientists that found a technique that searches for traces of the isotopes cesium-137 and strontium-90.

The reason is that these isotopes are only created by fission of Uranium 235, and between 1945 and 1963, 522 open-air atomic bomb blasts scattered these isotopes into the atmosphere, which then got into the soil, made its way into flax plants, which were used to create linseed oil, which was used as a binding agent in paint.

So if a painting shows traces of these isotopes in the paint, there is no way that it was created before 1945.

This technique has foiled hundreds of art forgers in the years since and has proven to be one of the most difficult challenges for future Wolfgang Baltracchis.

Human cloning has been a hot topic since the first mammal, Dolly the sheep, was cloned in 1996. And while no human clones have been made – that we know of – the research into cloning is saving lives through stem cell therapy.

The Starshade Space Probe is part of the New Worlds mission in which NASA is going to launch a huge shade to block out the light from stars so that we could possibly see Earth-like rocky planets.

In order to get the star shade into space, they’re employing the ancient art of origami to incredible effect.

Check out Robert Salazar’s blog detailing the process of designing the shade:

Bad Language: Why Being Bilingual Makes Swearing Easier

Many bilinguals report “feeling less” in their second language; it does not bear the same emotional weight as your native language.

Feeling less emotionally connected to your second language might make it easier to use highly emotional vocabulary, which is precisely what I was experiencing with my ease of swearing and talking about sensitive topics in English.

The scientific term for this is reduced emotional resonance of language. It is a fairly well-established phenomenon, but many specific questions still remain unanswered.

For example, what exactly makes one’s second language less emotional? How does this affect different immigrant communities?

This research project aims to address these questions by looking into the reasons and implications of reduced emotional resonance in bilinguals’ second language.




It is still unclear what exactly shapes emotional resonance of a language and in what way – results thus far have been inconclusive.

In the first part of my project, we are exploring which factors in a person’s language background contribute to reduced emotional resonance.

For example, is it influenced by the age at which you have learnt your second language? Does it matter how frequently and in which context you use the language?

Or is your emotional experience of a language predictable from whether you dream or can do maths in it?

To investigate these questions, my project uses eye-tracker technology in order to measure bilinguals’ pupil responses to emotional words in English.

Typically, when shown highly emotional words or pictures, people’s pupils dilate as a non-controllable, emotional reaction.

Previous research has shown the effect is smaller in bilinguals’ second language, which suggests reduced emotional resonance.

Understanding the reasons for why this happens can, in turn, help us explain how you experience a foreign language community, and how this could be taken into account in acculturation and adaptation.

However, not all the implications of reduced emotional resonance are negative – bilinguals can actually benefit from being able to approach things in a less emotionally involved way.

For example, bilinguals have been shown to be able to make more rational decisions in their second language.

Also, switching languages can be used as a tool in therapy when working through emotionally difficult or traumatising experiences.

Imagine how it would be if it were easier to talk about your emotions with your partner – maybe bilingual couples have a communicative advantage?

Ultimately, understanding the full scale of implications of reduced emotional resonance is a way to understand how bilinguals experience the world.

Ditching Microbeads: The Search For Sustainable Skincare

Is smoother skin worth more than having potable water or edible fish?

For years, research has shown that beauty products made with tiny microbeads, gritty cleansers that scrub off dead skin cells, have been damaging water supplies, marine life and the ecological balance of the planet.

Beat the Microbead, an international campaign to ban the plastic beads, reports that marine species are unable to distinguish between food and microbeads.

According to the campaign, “over 663 different species were negatively impacted by marine debris with approximately 11% of reported cases specifically related to the ingestion of microplastics“.

To make things worse, microbeads can act like tiny sponges, absorbing several other dangerous chemicals, including pesticides and flame retardants. As they ingest microbeads, marine animals also consume these other poisons.




The obvious solution to the microbead problem is to cut it off at the source.

But while major cosmetic companies like Johnson & Johnson, Unilever, and Procter & Gamble have pledged to phase out the use of microbeads in favor of natural alternatives, they also say that the shift could take several years.

And as more research is done, it appears that microbead replacements may come with dangers of their own.

Some of the natural replacements for microbeads also have negative consequences.

Greg Boyer, chair of the chemistry department at SUNY-College of Environmental Science and Forestry, says a possible negative consequence is with degrading sugars that biochemically “burn” the sugar for energy.

A variety of biodegradable ingredients are available to developers.

Victoria Fantauzzi, co-founder of Chicago-based La Bella Figura Beauty, says that her company recently released a facial cleanser that uses enzymes found in papaya and pineapple, ingredients known to effectively exfoliate skin cells.
