Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'

Space and time from Science Daily Feed - Mon, 07/22/2024 - 2:59pm
Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

There is mathematical proof in the pudding

Computers and Math from Science Daily Feed - Mon, 07/22/2024 - 12:51pm
In blockchain development, there is a rule of thumb that only two of scalability, security, and decentralization are valid simultaneously. However, the mathematical expression of that rule was still a work in progress. Researchers discovered a mathematical expression for the blockchain trilemma. In the formula for Proof of Work-based blockchains, including Bitcoin, the product of the three terms--scalability, security, and decentralization--is 1.

Genetic diagnostics of ultra-rare diseases

Computers and Math from Science Daily Feed - Mon, 07/22/2024 - 12:51pm
The majority of rare diseases have a genetic cause. The underlying genetic alteration can be found more and more easily, for example by means of exome sequencing (ES), leading to a molecular genetic diagnosis. ES is an examination of all sections of our genetic material (DNA) that code for proteins.

Maximizing hydrogen peroxide formation during water electrolysis

Matter and energy from Science Daily Feed - Mon, 07/22/2024 - 12:50pm
When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of industry. This, however, requires certain reaction conditions.

Foldable pouch actuator improves finger extension in soft rehabilitation gloves

Matter and energy from Science Daily Feed - Mon, 07/22/2024 - 12:50pm
Hand rehabilitation research has markedly benefited from the introduction of soft actuators in gloves. However, existing soft rehabilitation glove designs have several limitations in finger movements. In this regard, researchers recently succeeded in adding finger straightening or extension to soft rehabilitation gloves through a novel foldable pouch actuator without compromising the already existing functionality of finger bending or flexion. Their findings represent a significant leap in comprehensive hand rehabilitation.

Are AI-chatbots suitable for hospitals?

Computers and Math from Science Daily Feed - Mon, 07/22/2024 - 12:50pm
Large language models may pass medical exams with flying colors but using them for diagnoses would currently be grossly negligent. Medical chatbots make hasty diagnoses, do not adhere to guidelines, and would put patients' lives at risk. A team has systematically investigated whether this form of artificial intelligence (AI) would be suitable for everyday clinical practice. Despite the current shortcomings, the researchers see potential in the technology. They have published a method that can be used to test the reliability of future medical chatbots.

Aluminum scandium nitride films: Enabling next-gen ferroelectric memory devices

Matter and energy from Science Daily Feed - Mon, 07/22/2024 - 12:50pm
Aluminum scandium nitride thin films could pave the way for the next generation of ferroelectric memory devices, according to a new study. Compared to existing ferroelectric materials, these films maintain their ferroelectric properties and crystal structure even after heat treatment at temperatures up to 600 C in both hydrogen and argon atmospheres. This high stability makes them ideal for high-temperature manufacturing processes under the H2-included atmosphere used in fabricating advanced memory devices.

3D printing of light-activated hydrogel actuators

Computers and Math from Science Daily Feed - Mon, 07/22/2024 - 12:50pm
An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when the light is removed. Because this expansion and contraction can be performed repeatedly, the 3D-printed structures can serve as remotely controlled actuators.
