Saudi Arabia has called its giga-project Neom, a new city 33 times the size of New York City, “the world’s most ambitious project” — and it sounds it.
Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair, interact with a computer or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires.
By providing a fully portable, wireless brain-machine interface (BMI), the wearable system could offer an improvement over conventional electroencephalography (EEG) for measuring signals from visually evoked potentials in the human brain. The system’s ability to measure EEG signals for BMI has been evaluated with six human subjects, but has not been studied with disabled individuals.
The project, conducted by researchers from the Georgia Institute of Technology, University of Kent and Wichita State University, was reported on September 11 in the journal Nature Machine Intelligence.
Scientists have demonstrated that life’s process on Earth could have actually started with molecules that formed by mixing RNA and DNA.
If you are a Lifeboat subscriber or have been reading these pages for awhile, you may know why it’s called “Lifeboat”. A fundamental goal of our founder, board, writers and supporters is to sustain the environment, life in all its diversity, and—if necessary—(i.e. if we destroy our environment beyond repair, or face a massive incoming asteroid), to prepare for relocating. That is, to build a lifeboat, figuratively and literally.
But most of us never believed that we would face an existential crisis, except perhaps a potential for a 3rd World War. Yet, here we are: Burning the forests, killing off unspeakable numbers of species (200 each day), cooking the planet, melting the ice caps, shooting a hole in the ozone, and losing more land to the sea each year.
Regading the urgent message of Greta Thunberg, below, I am at a loss for words. Seriously, there is not much I can add to the 1st video below.
Information about climate change is all around us. Everyone knows about it; Most people understand that it is real and it that poses an existential threat, quite possibly in our lifetimes. In our children’s lives, it will certainly lead to war, famine, cancer, and massive loss of land, structures and money. It is already raising sea level and killing off entire species at thousands of times the natural rate.

A new, non-invasive brain stimulation treatment shows promise in enhancing memories and cognitive function in those with Alzheimer’s disease. Transcranial electromagnetic treatment (TEMT) increases functional connectivity within the cingulate cortex. TEMT is also able to penetrate the brain to break up amyloid-beta and tau deposits, slowing the progression of Alzheimer’s disease.
The news: According to a report in the Financial Times, a team of researchers from Google led by John Martinis have demonstrated quantum supremacy for the first time. This is the point at which a quantum computer is shown to be capable of performing a task that’s beyond the reach of even the most powerful conventional supercomputer. The claim appeared in a paper that was posted on a NASA website, but the publication was then taken down. Google did not respond to a request for comment from MIT Technology Review.
Why NASA? Google struck an agreement last year to use supercomputers available to NASA as benchmarks for its supremacy experiments. According to the Financial Times report, the paper said that Google’s quantum processor was able to perform a calculation in three minutes and 20 seconds that would take today’s most advanced supercomputer, known as Summit, around 10,000 years. In the paper, the researchers said that, to their knowledge, the experiment “marks the first computation that can only be performed on a quantum processor.”
Quantum speed up: Quantum machines are so powerful because they harness quantum bits, or qubits. Unlike classical bits, which are either a 1 or a 0, qubits can be in a kind of combination of both at the same time. Thanks to other quantum phenomena, which are described in our explainer here, quantum computers can crunch large amounts of data in parallel that conventional machines have to work through sequentially. Scientists have been working for years to demonstrate that the machines can definitively outperform conventional ones.

The first population-level study on the link between gut bacteria and mental health identifies specific gut bacteria linked to depression and provides evidence that a wide range of gut bacteria can produce neuroactive compounds. Jeroen Raes (VIB-KU Leuven) and his team published these results today in the scientific journal Nature Microbiology.[br /][br /].
