A new study examining data from half a million people between 38 and 73 found that seven hours of sleep per day seems to hit the sweet spot. Sleeping an hour more or less than that seems to lead to a measurable reduction of the cognitive performance.

One consequence of type 2 diabetes can be that the illness destroys blood vessels and hinders the organism to regrow them. However, a 45-minute session of moderate intensity exercise can counter this problem and support the organism in regrowing blood vessels, a new study finds.

Spending time outdoor in nature does not only benefit health directly, but seems also to have the indirect effect that people being outside have a more healthy diet with higher fruit and vegetable consumption, a new study finds.

In a study with more than 250 sportspeople it was found that those who are very critical about themselves tend also to burn out more easily. It is concluded that people should be less self-critical and celebrate their successes.

People who see the beauty in the everyday seem to feel that they lead a more meaningful life, some new studies with thousands of participants suggest. The feeling that life is meaningful is related to firstly the feeling that one's life is coherent, secondly that there are satisfying long-term goals, and thirdly that the life matters in the grand scheme of things.

When we eat, not only the material but also its structure is important. Scientists have studied this with a normalized form of chocolate and found that some S-shaped forms with many twists and cracks break in an interesting form and give test people most pleasure.

A new study finds that brisk walking over a lifetime could lead on average to a biological age (measured by telomere length) reduced by 16 years compared to the actual age and lead to a 20 year greater life expectancy.

In Nigeria, electric 12-seater buses are built as a first. They are made from scratch and have a reach of 200 km per full charge. The project contributes to the efforts to reduce CO2 emissions.

Noninvasive sound therapy with microsecond long pulses has been tested on liver cancer in rats. In 80 percent of the animals, destroying 50 to 75 percent of the tumour volume resulted in the immune system of the rats clearing the rest and preventing the recurrence of the tumours.

In Columbia there is the danger that biodiversity declines steeply to provide areas for agriculture. A model has been developed to determine how limited financial resources are best targeted to counteract this loss in biodiversity, also considering the potential opportunity cost of conversation, empowering local communities including indigenous communities.

Transistors are essential components of computers. Now using a new type of transistor based on graphene and chromium oxide rather than silicon five percent of the energy needed by the transistor may be saved.

A new study finds that physical exercise may protect the brain volume of older people by reducing insulin and BMI levels, thereby reducing the risk of dementia.

Although different mammals have different average lifespans, they also show a different amount of mutations per year (mice 800 per year, dogs 249, lions 160, giraffes 99, and humans 47). One invariant seems to be that they all have about 3200 mutations across their lifetime. The insight may offer another puzzle piece in understanding ageing.

There is now a better understanding how Gram-negative bacteria build their outer membrane from the two main, non-protein components, lipids and sugars, to protect themselves from antibiotics. If this process could be disrupted this would make the bacteria vulnerable against antibiotics.

A study found that the bird biodiversity in the Amazon is to a large degree due to the dynamic changes of rivers in small areas, creating ecological niches.

A new sound device for deeper sleep has been developed. It works by playing precisely timed sounds through earphones. While this was possible before under lab conditions, the new device is wearable.

The European Union wants to produce in an initiative, called "Destination Earth", a digital replica of the Earth so that politicians and others can more directly see how their decisions affect climate change, rising temperatures, and in consequence the future of our planet.

For long it has been known that zinc is important to the immune system. After experiments with mice it is now also understood why: Zinc is important for the regeneration of the thymus, an organ that produces T-cells and is needed for the development of the T-cells as well.

In experiments with mice, a new nasal spay has proved highly effective in preventing and treating Covid-19 caused by the Delta variant. It is assumed to be effective against all currently known Covid-19 variants. It works by blocking cells from the virus.
