Older adults who sleep just five hours a night or fewer have a greater risk of developing more than one chronic disease, new research shows. The findings underscore the importance of healthy sleep patterns throughout life, and especially in middle and old age.

The new study, published in PLOS Medicine, examined sleep duration and its effect on multimorbidity—or the occurrence of more than one chronic condition, like diabetes and cardiovascular disease, at once. People ages 50 or older who slept a total of five hours a night or less were found to have at least a 30% greater risk of multimorbidity.

Prior studies have largely focused on the link between sleep and the development of individual chronic diseases, but it’s been unclear how sleep duration contributes to the development of multiple chronic conditions. The new findings add to growing evidence suggesting that sleep deficiencies can affect health outcomes.

It gives new meaning to the phrase “speak your mind.

Do you remember how legendary cosmologist Stephen Hawking communicated using his special screen-equipped chair? Well, that was a brain-computer interface (BCI), a device that allows a person to communicate using their brain signals.

The new method for harnessing the power of the Sun is “cheaper than traditional fusion approaches.”

U.K.-based startup First Light Fusion is developing its prototype Big Friendly Gun (BFG) in a bid to achieve nuclear fusion without relying on lasers and powerful magnets.

“This is the first system that combines all the pieces; efficient energy harvesting, energy storage, and the controlled brain stimulator.”

Researchers have devised an ingenious way to power deep brain simulators — Using the person’s breathing movements.

About 150,000 deep brain stimulators are implanted every year. Normally placed under the skin in the chest area with electrodes implanted in the brain, these stimulators are known to help with neurological and psychiatric diseases when traditional treatments fail.

Earth’s low orbit is filling up, meaning radiation-tolerant cell designs are required as satellites head to higher orbits. Will these new ones do?

Scientists have developed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. According to a new study published today (Nov .08) in the Journal of Applied Physics by AIP Publishing.

Significantly, the ultra-thin solar cells not only surpass earlier suggested thicker solar cells in resilience to irradiation; they also produce the same amount of power from converted sunlight after 20 years of use. Additionally, the novel photovoltaic cells could reduce load and considerably lower launch expenses. Barthel.

“This was completely unexpected.”

Stars are essentially large fiery balls of plasma, which is often referred to as the “fourth state of matter” as it forms when gas is heated into a soup of positively charged ions and negatively charged electrons.

The star’s magnetic field is so strong it appears to have “frozen” its surface into a solid outer crust, a press statement reveals.

The Large Hadron Collider is one of the most important scientific instruments in the world — and also one of the biggest humans have ever built.

The Large Hadron Collider is the world’s most powerful particle accelerator, situated along the border between Switzerland and France, just outside the Swiss city of Geneva. Still, that description doesn’t quite do it justice.

It is also one of the largest scientific instruments ever built; the result of a decade of collaboration between over 100 countries, hundreds of universities and scientific institutes, and more than 10,000 scientists and researchers.

His work will be published soon.

Shanghai-born Zhang Yitang is a professor of mathematics at the University of California, Santa Barbara. If a 111-page manuscript allegedly written by him passes peer review, he might become the first person to solve the Riemann hypothesis, The South China Morning Post (SCMP)

The Riemann hypothesis is a 150-year-old puzzle that is considered by the community to be the holy grail of mathematics. Published in 1,859, it is a fascinating piece of mathematical conjecture around prime numbers and how they can be predicted.
