Secret immune cell tunnels found in human skulls

Posted by in categories: biotech/medical, neuroscience

Hidden tunnels which link the human skull to the brain have been discovered by scientists, leading to hopes the breakthrough may help in stroke and Alzheimer’s research.

Researchers believe that the passages provide a quick channel for immune cells to reach the brain from the bone marrow in the skull.

Previously it was through that immune cells formed in the bone marrow of the limbs was transported up to the brain to clear out infection.

In sync: How cells make connections could impact circadian rhythm

Posted by in categories: biotech/medical, information science, neuroscience

If you’ve ever experienced jet lag, you are familiar with your circadian rhythm, which manages nearly all aspects of metabolism, from sleep-wake cycles to body temperature to digestion. Every cell in the body has a circadian clock, but researchers were unclear about how networks of cells connect with each other over time and how those time-varying connections impact network functions.

In research published Aug. 27 in PNAS, researchers at Washington University in St. Louis and collaborating institutions developed a unified, data-driven computational approach to infer and reveal these connections in biological and chemical oscillatory networks, known as the topology of these , based on their time-series data. Once they establish the topology, they can infer how the agents, or cells, in the network work together in synchrony, an important state for the brain. Abnormal synchrony has been linked to a variety of brain disorders, such as epilepsy, Alzheimer’s disease and Parkinson’s disease.

Jr-Shin Li, professor of systems science & mathematics and an applied mathematician in the School of Engineering & Applied Science, developed an algorithm, called the ICON (infer connections of networks) method, that shows for the first time the strength of these connections over time. Previously, researchers could only determine whether a connection existed between networks.

Singapore hit by ‘most serious’ cyberattack, resulting in theft of health data of 1.5 million people – including the prime minister

Posted by in categories: biotech/medical, cybercrime/malcode, government, health, military

Wealthy Singapore is hyper-connected and on a drive to digitise government records and essential services, including medical records which public hospitals and clinics can share via a centralised database.

But authorities have put the brakes on these plans while they investigate the cyberattack. A former judge will head a committee looking into the incident.

While the city state has some of the most advanced military weaponry in the region, the government says it fends off thousands of cyberattacks every day and has long warned of breaches by actors as varied as high-school students in their basements to nation states.

Global race for transformative molten salt nuclear includes Bill Gates and China

Posted by in categories: government, nuclear energy

Unlike Nuclear fusion which has never had net generation of power, molten salt nuclear fission power had 2.5 megawatts of net power generation from a US nuclear prototype back in the 1960s. The US government had major work on molten salt nuclear reactors form the 1950s through the 1970s.

There is now a multi-billion race from many US companies and China and Canada and European countries to develop molten salt nuclear power.
