Savant syndrome is a strange condition that gives people unique abilities. Although savant syndrome is very rare reported cases gain genius-like abilities in narrow domains. But how can we explain savant syndrome? And could we induce savant syndrome in normal people?

Savant syndrome is characterized by unique skills in art, music, mechanics, calendar calculation or maths. Savant syndrome can be acquired through injuries or frontotemporal dementia or be developed in people with autism spectrum disorder. In acquired savant syndrome and autism spectrum disorder, unique connections in the brain led to the condition. In savant syndrome, we often find that the left hemisphere is damaged and the right brain hemisphere has to compensate for this. Based on this observation, we can partially induce savant syndrome like abilities through transcranial magnetic stimulation. Many questions concerning savant syndrome remain but this condition is truly amazing.

We all know that exercise is good for our health. But besides lowering the risk of obesity or type II diabetes, exercise has also been shown to benefit our brain. More precisely, exercise modifies parts of the brain and improves memory, attention and improves mood. Regular exercise further lowers the risk to suffer from dementia or depression. But how does exercise benefit our brains?

Philosophers have speculated for centuries that exercise promotes our brain functionality but only a few decades ago, scientists uncovered that this is true. Studies have shown that children who are more athletic perform better in creativity, concentration, maths verbal and IQ tests. These children also tend to have a larger hippocampus and basal ganglia both of which are important for memory and attention span. Adults who started to workout regularly also have changes in their brain and perform better in various tests. There are several mechanisms which explain this phenomenon. When we exercise, brain cells release VEGF which helps to supply the brain with oxygen. Moreover, neurotrophins are released when we workout which helps the survival of brain cells. Exercise also seems to improve neuroplasticity through the same pathways. Since exercise leads to the release of neurotransmitters such as serotonin, workouts also have been used to treat mental disorders such as depression. In various studies it was seen exercise helps to alleviate the symptoms of people who suffer from major depression.
The literature suggests roughly 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week might be optimal to curb the risk of heart disease and 19 other chronic diseases. Concerning brain health, 120 minutes of moderate exercise a week might be enough to get all the benefits we have seen before. But even if you do less you might see a difference in the long run. In general, aerobic exercise seemed to have the best impacts on your brain. Jogging, running, swimming and all other forms of aerobic sports might give the benefits we have seen in this video!

Generative AI, which is based on Large Language Models (LLMs) and transformer neural networks, has certainly created a lot of buzz. Unlike hype cycles around new technologies such as the metaverse, crypto and Web3, generative AI tools such as Stable Diffusion and ChatGPT are poised to have tremendous, possibly revolutionary impacts. These tools are already disrupting multiple fields — including the film industry — and are a potential game-changer for enterprise software.

All of this has led Ben Thompson to declare in his Stratechery newsletter to declare generative AI advances as marking “a new epoch in technology.”

The death toll from the earthquake in Turkey and Syria is likely to “more than double”, according to a United Nations emergency relief coordinator.

Martin Griffiths, speaking to Sky News on Saturday, said he expected tens of thousands more deaths.

At least 24,596 people have been confirmed dead after the 7.8 magnitude earthquake struck southern Turkey and north-western Syria on Monday, with multiple aftershocks.

The new disease could provide insights into how the cell’s recycling system contributes to a healthy brain. Researchers at the National Institutes of Health have discovered a new neurological condition characterized by issues with motor coordination and speech. They identified three children with the condition, two siblings and an unrelated child.

Through optomechanical experiments, scientists aim to delve into the boundaries of the quantum realm and lay the groundwork for the creation of highly sensitive quantum sensors. In these experiments, everyday visible objects are coupled to superconducting circuits through electromagnetic fields.

To produce functional superconductors, these experiments are conducted inside cryostats at a temperature of around 100 millikelvins. However, this is still far from low enough to truly enter the quantum world. In order to observe quantum effects on large-scale objects, they must be cooled to nearly absolute zero.

Absolute zero is the theoretical lowest temperature on the thermodynamic temperature scale. At this temperature, all atoms of an object are at rest and the object does not emit or absorb energy. The internationally agreed-upon value for this temperature is −273.15 °C (−459.67 °F; 0.00 K).
