Picking a Fragrance


If you want to explore the world of fragrances, there are few better entry points than one of Luca Turin’s guides. Turin is a fragrance critic and biophysicist, with a controversial theory about how scents are linked to vibration frequencies. Along with his book The Secret of Scent – which details the history and science behind his theory of olfaction – he’s also written a number of popular consumer guides. There’s Parfums: Le Guide, which is in French, and then a couple of English books that he’s co-authored with his partner, Tania Sanchez – Perfumes: The A-Z Guide and The Little Book of Perfumes

What makes Turin great is that he’s not only knowledgeable, he also has an opinion and isn’t afraid to share it. Rare is the writer nowadays who both knows what he’s talking about and hasn’t been bought out by companies. In Perfumes: The A-Z Guide, for example, he regularly pans Creed – a fragrance house that’s not only commercially successful, but also widely popular in the fragrance community. For the company’s Millésime Imperial, Turin writes:

I'M GOING TO COLLEGE TO BE AN ART MAJOR AND I GET WEIRD LOOKS BC PEOPLE THINK I WONT BE ABLE TO GET A JOB AFTER I GRADUATE ᕕ( ᐛ )ᕗ

Oh no! I’ll pray (if you’re okay with that) that you get work! 


My turn: 

I’m still indecisive about what to go to college for. I’m passionate about writing, but even if I get published that won’t put food on the table. Most authors besides J.K. Rowling have jobs on top of being an author. 

I’ve thought about everything from Beekeepers, to Videogame scriptwriters, to mailmen, to quantum biophysicists. 

Targeted and gentle treatment of tumors: percutaneous electrical tumor therapy (PET)

Percutaneous electrical tumor therapy (PET) is a targeted and gentle method based on the findings of the Italian biophysicist Luigi Galvani (1737 – 1798). By means of two charged electrodes, a direct current is supplied to the tumor of the to be treated tissue.

The resistance in the cancer cells is lower than in healthy tissue cells. This means that the electrical conductivity is higher in tumor cells than in healthy tissue due to the degenerate state of the cell.

These physicochemical property uses gentle electrical percutaneous tumor therapy (PET). Healthy tissues or organs are not damaged by the higher resistance to the diseased tissue.

Dr. Siebenhüner commented the physiological process of percutaneous electrical tumor therapy (PET) for the targeted and gentle treatment of tumors.

„The electrodes applied to percutaneous electrical tumor therapy (PET) lead to an ion flow of positively charged ions to the cathode and a negative ion flux to the anode.”

The change in pH results in depolarization of the cell membranes. Resulting hydrochloric acids cause a chemical metabolic disorder of tumor cells and triggers programmed cell death. The tumor dies.

The target-specific and gentle percutaneous electrical tumor therapy (PET) is particularly suitable for the treatment of breast, skin, liver, stomach, lung, lymph, prostate tumors and metastases, which hardly respond to chemotherapy or radiotherapy.

  • breast cancer
  • prostate cancer
  • Lymph metastasis / lymphoma
  • Primary lung cancer and lung metastases
  • Primary hepatic carcinoma and liver metastases / liver cancer
  • Primary gastric cancers and gastric metastases / stomach cancer
  • All other tumors and metastases in the intra – abdominal
  • Skin cancer / skin metastases / skin cancer / cancer black / white cancer

Water Droplet-Powered Computers Could Run Mini Science Labs

Whereas conventional microelectronics shuffle electrons around wires, in recent years, scientists have begun developing so-called microfluidic devices that shuffle liquids around pipes. Although microfluidic devices are dramatically slower than conventional electronics, the goal is not to compete with electronic computers on traditional computing tasks such as word processing. “The fundamental limits of computation, such as how fast you can go or how small devices can be, are based in how information has to be represented in physical entities,” study co-author Manu Prakash, a biophysicist at Stanford University, told Live Science. http://dlvr.it/BL09Ct

Lets acknowledge these great women scientists, who never got appreciated!

Today lets remember some unsung heroes or rather heroines who slogged hard all their life in laboratories and in the end faded into the oblivion, they even had to bear the frustration of seeing their male counterparts win Nobel Prize for the work which they actually did!

Here is my tribute to some of these great pioneers, I request you all to add to this list because we all know, there are many more such women innovators whose sweat and blood went unrecognized.

Esther Lederberg:

Esther was a microbiologist, conducted groundbreaking research in the field of genetics. She developed basic techniques that have gone a long way towards helping scientists understand how genes work.

Her work helped her husband, Joshua, win a Nobel prize in 1958, but she was not cited in the award. 

Rosalind Franklin:

This British biophysicist  was a pioneering X-ray crystallographer.

Her image of the DNA molecule was critical to deciphering its structure - one of the biggest and most important scientific breakthroughs of the 20th Century - but it was James Watson, Francis Crick and Maurice Wilkins who received the 1962 Nobel Prize in physiology or medicine for their work.

Ida Tacke:

She found two new elements, rhenium and masurium, that Dmitri Mendeleev had predicted would form part of the periodic table.

She gets credit in the science books for the discovery of rhenium.

But masurium is now known as technetium, the discovery of which is attributed to Carlo Perrier and Emilio Segre.

Tacke’s evidence was ignored until Perrier and Segre artificially created the element in a laboratory.

Tacke is also credited with being the first person to open up the idea of nuclear fission.

Lise Meitner:

Her work in nuclear physics led to the discovery of nuclear fission - where atomic nuclei split in two.

This laid the groundwork for the atomic bomb.

After moving to Berlin in 1907, Meitner collaborated with chemist Otto Hahn over many decades.  

But Hahn published their findings without including Meitner as a co-author.

And Hahn went on to win the 1944 Nobel Prize in chemistry for his contributions to splitting the atom.

Chien-Shiung Wu:

She was one of the most important physicists of the 20th Century.

She participated in the development of the atom bomb, as part of the Manhattan Project. Yet few know her name today.

In the 1950s, two theoretical physicists, Tsung-Dao Lee and Chen Ning Yang, asked Wu to help disprove what is known in physics as the law of parity.  Wu’s experiments turned this law on its head.  

This landmark moment in physics led to a 1957 Nobel Prize for Yang and Lee, but not for Wu, who was left out despite the key role she played.

Henrietta Leavitt:

She was an astronomer who potted a pattern between the brightness of a star and its distance from the Earth. This led her to uncover what is known as the period-luminosity relationship, allowing scientists to calculate how far away a star was from Earth based on its brightness.

Artificial Jellyfish From Rat Cells

Not satisfied by merely turning other animals into glow-in-the-dark dolls, scientists have used rat cells and silicone to build an artificial jellyfish.

Dubbed the ‘medusoid’ – though lacking the ability to turn people into stone – it swims and behaves just like a real jelly fish when placed in an electric field.The jellyfish was designed by Harvard biophysicist Kit Parker, who is now planing to build other life forms. If he’s open for suggestions, I’d like to vote for Sharktopus.
