6:17 PM | Proteins conspire to make breast cancer cells resistant to drug treatment
Scientists at Sanford-Burnham Medical Research Institute (Sanford-Burnham) provide compelling and conclusive evidence that antiestrogen resistance in breast cancer cells requires the interaction between proteins called BCAR1 and BCAR3. In the study, published in the Journal of Biological Chemistry, the researchers also identified a signaling pathway that is crucial for drug resistance mediated by this proteinRead More

As if water didn’t have enough unusual aspects (of interest to biologists, since, well, it’s only the primary solvent in all living organisms) a paper out today highlights its disobedience to a fundamental law describing molecular diffusion. Aqueous guanidium hydrochloride ‒ a “water neutral” denaturant used to produce chemical unfolding of proteins. The particular paper I’m thinking of is Exploring Early Stages of the Chemical Unfolding of Proteins at […]

Modernity II An obvious missing addition in my previous Modernity post was (as pointed out by Franklin Chen in the comments) was LaTeX, developed in the early 1980s as a set of macros for TeX (released in 1978). By the way, if you prefer … Continue reading →

4:39 PM | Can Fruit Flies Glow in the Dark?
Question: How is a fruit fly like a firefly? No, this is not an obvious answer (their names start with the letter “f”) or the beginning of a bad entomology joke. These two organisms may both be winged insects, but as it turns out, what makes the firefly light show such a special treat on […]

2:52 PM | Sex in the News: April 8-17
The last week (or so) in sexy news: The world learned that lab-grown vaginas are a thing, and that they have been successfully transplanted into women born with a rare birth defect. Girls born with what’s snappily called Mayer-Rokitansky-Kuster-Hauser syndrome have either an underdeveloped or completely missing vagina. The transplant surgery has helped 4 women so far experience … Continue reading →

2:49 PM | Ecco il drone stampato in 3D
In gergo tecnico si chiama unmanned aherial vehicle (Uam). Più colloquialmente, è un drone di un metro e mezzo messo a punto dagli ingegneri dell'Advanced Manufacturing Research Centre (Amrc) alla University of Sheffield: la sua particolarità è che è stato stampato in 3D grazie a una nuova tecnica sviluppata dagli scienziati britannici, chiamata fused deposition modelling. Le versioni attualmente in produzione, spiegano gli autori della ricerca, richiedono […]

2:47 PM | Il complesso ruolo della guaina mielinica
La guaina mielinica è una struttura biancastra che avvolge gli assoni dei neuroni, e permette di trasmettere velocemente i segnali nervosi all'interno del cervello. Fino ad oggi si riteneva che tutti i neuroni avessero lo stesso tipo di guaina mielinica, ma un nuovo studio dell'Università di Cambridge, a cui hanno collaborato anche i ricercatore dell'Università di Torino, mette oggi in dubbio questo paradigma. I risultati, pubblicati sulle pagine di Science, suggeriscono […]

2:35 PM | Moon dust probe crashes
A NASA spacecraft that studied lunar dust vapourized into its own cloud of dust when it hit the far side of the Moon, as planned, in a mission-ending impact on 17 April. Launched last September, the Lunar Atmosphere and Dust Environment Explorer (LADEE) finished its primary mission in March. In early April, on an extended mission, it made close passes as low as 2 kilometres above the surface, gathering science data on more than 100 low-elevation orbits. Mission controllers deliberately crashed […]

2:33 PM | Succesvol diëten met religieus fanatisme
Al een week is in de meeste supermarkten hier in West-Jeruzalem geen kruimel brood meer te vinden. Ook de nijvere consument die het heft dan maar in eigen handen wil nemen, kan nauwelijks nog aan meel of gist komen. De pasta is verstopt achter grote plastic doeken, net als de cruesli en andere ontbijtgranen, en het bier natuurlijk. Het is Pesach, dus al het gefermenteerde graan is uit den boze:...

2:06 PM | A thorn by any other name
When dangerous situations arise for plants, the choice between flight or fight is a simple one. They abide by the stand your ground law and always fight. Such a lifestyle choice means that plants employ a variety of weapons to stave off extinction. Thorns are one of the more obvious botanical defenses. Their appearance is […]

2:02 PM | Cloak of Invisibility very much a possibility!
Harry Potter’s invisibility cloak is one accessory every Muggle would like to include in their wardrobe. For those of you who are not familiar with Harry Porterterminology, Muggles is the term, magic folk use to call non magical folk (and invisibility cloak is self-explanatory). We Muggles may not possess magical powers to conjure an invisibility cloak, but we surely have technology and genius, to fashion ourselves one.A simple principle exists behind the theory of invisibility. We can […]

1:59 PM | Acoustic lasers, tomatoes, and spaceships: Endi Webb talks about his life between writing and physics
If you've been closely watching Kindle book rankings on Amazon this month, as I have (ahem), you may have noticed a new star rising: The Terran Gambit, Book I in the Pax Humana Saga, came out on March 19 and quickly rose to the top 10 Kindle books in 4 different science fiction categories! Author Endi Webb is not only an accomplished science-fiction writer, but also an experimental physicist with whom, turns out, I share a common recent employer -- small world, right? So, of course, Endi had to […]

Wildlife cameraman Doug Allen is cold weather specialist."... he did not expect an easy assignment – it is usually -32°C in April, the wind is vicious and hauling cameras in the deep snow is a nightmare. After walking five or more hours a day and watching polar bear dens in the snow slopes for 23 days, however, Allan had seen just one mother bear and her cub."

12:21 PM | It’s Time to Retire the Use of the Term “Squamate” from Public Discourse
Let’s face it, “squamate” doesn’t work. It’s an ugly word, and most people don’t know what it means–if anything, it conjures up “squamous cell carcinoma,” a type of skin cancer. More importantly, the term is not needed. Squamate comes from the scientific order Squamata, the lizards and snakes. But we know that snakes evolved from […]

11:32 AM | Se le femmine (d'insetto) hanno il pene
La femmina introduce il suo pene nella vagina del maschio. No, non ci siamo sbagliati a invertire i sessi e i relativi organi sessuali: su Current Biology infatti un gruppo di ricercatori giapponesi, svizzeri e brasiliani mostra il caso di animali, insetti in questo caso, con genitali a sesso invertito, in cui le femmine hanno il pene, e i maschi l’equivalente di una vagina. Gli insetti studiati dai ricercatori sono quattro specie del genere Neotrogla, sono sati scoperti in Brasile e […]
