Clusters composed of a few atoms tend to be spherical. They are usually organized in shells of atoms around a central atom. This is the case for many elements, but not for gold! Experiments and advanced computations have shown that freestanding clusters of twenty gold atoms take on a pyramidal shape. They have a triangular ground plane made up of ten neatly arranged atoms, with additional triangles of six and three atoms, topped by a single atom.

The remarkable tetrahedral structure has now been imaged for the first time with a scanning tunnelling microscope. This high-tech microscope can visualise single atoms. It operates at extremely low temperatures (269 degrees below zero) and uses quantum tunnelling of an electrical current from a sharp scanning metallic tip through the cluster and into the support. Quantum tunnelling is a process where electrical current flows between two conductors without any physical contact between them.

The researchers used intense plasmas in a complex vacuum chamber setup to sputter gold atoms from a macroscopic piece of gold. “Part of the sputtered atoms grow together to small particles of a few up to a few tens of atoms, due to a process comparable with condensation of water molecules to droplets,” says Zhe Li, the main author of the paper, currently at the Harbin Institute of Technology, Shenzhen. “We selected a beam of clusters consisting of exactly twenty gold atoms. We landed these species with one of the triangular facets onto a substrate covered with a very thin layer of kitchen salt (NaCl), precisely three atom layers thick.”

The study also revealed the peculiar electronic structure of the small gold pyramid. Similar to noble gas atoms or aromatic molecules, the cluster only has completely filled electron orbitals, which makes them much less reactive than clusters with one or a few atoms more or less.

Whenever someone refers me to a story with alarming facts that should surprise or outrage any thinking human, my spider-sense is activated. Does the story make sense? Is it plausible? If the message contains evidence of being repeated (or forwarded to more than two friends), then whatever is claimed is almost certain to be false.

If the subject is important to me—or if there is any chance that it might influence my view of the world, I check it at Snopes. The reputable web site confirms or debunks many urban legends and all sorts of viral web hype.

You never know what you might learn at Snopes. You can easily be lured into a rabbit hole, digging into the site beyond whatever prompted your visit in the first place.

Fact-checking can be fun! For example:

VITAMINS-Nutrients have long been described as healers-Life extending amino acids-chemicals… As has been done in the past holds true presently. There are trained professionals who for one reason or another attack the vitamin industry.

(Many claiming that vitamins do nothing and are washed from the body???)

How then did niacin extraction and synthesizing and being put into foods help end many sicknesses??? Yes Niacin is listed as a vitamin and a medicine…

Researchers at Johns Hopkins Medicine have successfully used a laser-assisted imaging tool to “see” what happens in brain cells of mice learning to reach out and grab a pellet of food. Their experiments, they say, add to evidence that such motor-based learning can occur in multiple areas of the brain, even ones not typically associated with motor control.

“Scientists should be looking at the entire brain to understand specific types of learning,” says Richard Huganir, Ph.D., Bloomberg Distinguished Professor and Director of the Solomon H. Snyder Department of Neuroscience at the Johns Hopkins University School of Medicine. “Different parts of the brain contribute to learning in different ways, and studying brain cell receptors can help us decipher how this works.”

The work, say the researchers, may ultimately inform efforts to develop treatments for learning-based and neurocognitive disorders.

Doctors believe a health food supplement caused acute liver failure in an otherwise healthy 23-year-old Amarillo woman.

Emily Goss is starting the new year, with a new routine. She checks her vitals to make sure her body isn’t rejecting the new liver doctors implanted Christmas Day in an effort to save her life.

Do you ever wish you could just turn on the happy chemicals in your brain? Imagine how much easier it would make getting out of bed each morning, getting even the most tedious parts of your job done, and finding the energy to consistently show up as your best self for the people you care about the most. But is it really possible – never mind advisable – to try and train our brains for more happiness?

“The quest for good feelings is nature’s survival engine,” explained Professor Loretta Breuning, founder of the Inner Mammal Institute, when I interviewed her recently. “For example, animals seek food to relieve the bad feeling of hunger. They seek warmth to relieve the bad feeling of cold. And happy chemicals start flowing before a mammal even eats or warms up because the brain turns them on as soon as it sees a way to meet a need.”

Scientists have uncovered a crucial change in cancer cells that allows them to spread around the body – by switching from sugar to fatty acids to fuel their growth.

Changing their ‘diet’ in this way allows tumour cells to set up shop at new sites where resources such as glucose – their preferred food source – are limited.

Researchers at The Institute of Cancer Research, London, found that a protein called AKR1B10 helps cells adapt the ways in which they get their energy.

Would be cool to see Tesla use more recycled components.

McDonald’s used to send 62 million pounds of coffee chaff to landfills. But the company partnered with Ford Motor Company with hopes to eliminate their waste to landfills. The research team at Ford has already been using agave, wheat, and even denim byproducts to make car parts. They discovered that chaff can be used as well. Here’s an inside look of the process.
