When radiochemist Jennifer Shusterman and her colleagues got the first results of their experiment, no one expected what they saw: Atoms of a weird version of the element #zirconium had enthusiastically absorbed neutrons.
Zirconium-88 captures neutrons with extreme efficiency, and scientists don’t yet know why.
We take a somewhat humorous look at the messaging and the comfort stories people tell themselves to distract themselves from seeing why age-related diseases and dying from them is a problem that needs solving.
Here’s what might be considered a paradox: right now, the Facebook page of Death Cafe—a place where you go to talk about death—is a rather lively place, whereas pages about life extension are comparatively rather dead places. This screenshot shows the activity of a Death Cafe post:
There is no doubt that the subscribers of the Death Cafe page are quite engaged, but if the average message that the page aims at conveying is the same as in the text snippet above, then there is no paradox at all. The core of that message is “don’t worry, death is nothing to fear” (which, incidentally, implies you don’t have to engage in any extra effort to prevent death), whereas the core message of a life extension page is, “death is a problem, but hey—with some effort, we can beat it. Maybe.” That’s a bit like a kiosk giving candy away for free right next to another kiosk that first serves you overcooked broccoli and then says that you might get a nice present decades from now, assuming that you work hard enough for it—where do you think most people would flock to? Exactly.
#MachineLearning and #ArtificialIntelligence are revolutionising the online world. They are capable of reducing costs, analysing data, recognising patterns and trends we can’t see with the human eye and making real- time decisions. Now, they are being used to help prevent financial fraud and they’re learning how to do it better every day.

Now, they are being used to help prevent financial fraud and they’re learning how to do it better every day.
Currently it is estimated that cybercrime costs the global economy approximately $600 billion, with one of the most common forms being credit card fraud which has grown considerably with the increase in the online market. As more and more people chose to transact online it is becoming increasingly important for financial services to invest in better, faster and more accurate fraud detection and prevention techniques.
How our data helps protect us
How do you separate carbon dioxide from carbon monoxide? One way, showcased by a new study from Kanazawa University, is to use a bowl of vanadium. More precisely, a hollow, spherical cluster of vanadate molecules can discriminate between CO and CO 2, allowing potential uses in CO 2 storage and capture.
At the molecular scale, small objects can fit inside larger ones, just like in the everyday world. The resulting arrangements, known as host-guest interactions, are stabilized by non-covalent forces like electrostatics and hydrogen bonds. Each host will happily take in certain molecules, while shutting out others, depending on the size of its entrance and how much interior space it can offer the guest.
Anion structures of CH 2 Cl 2 (guest)-inserted V12 (left) and guest-free V12 are shown. Orange and red square pyramids represent VO 5 units with their bases directed to the center of the bowl, and the inverted VO 5 unit. Green and black spheres represent Cl and C, respectively. Hydrogen atoms of CH 2 Cl 2 are omitted for clarity. (Image: Kanazawa University)
