The reliable generation of random numbers has become a central component of information and communications technology. In fact, random number generators, algorithms or devices that can produce random sequences of numbers, are now helping to secure communications between different devices, produce statistical samples, and for various other applications.
Scientists found that water in our solar system is likely billions of years older than the sun by studying the protostar V883 Orion, linking water from the interstellar medium to our solar system.
This research suggests that water in our solar system was formed long before the sun, planets, and comets, indicating that planetary systems.
A bioresorbable, wireless hydrogel (metagel) sensor, encompassing both biodegradable and stimulus-responsive hydrogels for ultrasonic monitoring of intracranial signals, was implanted into intracranial space with a puncture needle and deformed in response to physiological environmental changes.
Listen to this episode from Mind Chat on Spotify. Keith and Philip interview David Papineau (Professor of Philosophy at King’s College London) about his recent book ‘The Metaphysics of Sensory Experience’. David is also a materialist who believes in consciousness, so there’ll probably be a big old fight about that too.

Scientists have discovered that CAR T cells, traditionally used in cancer treatment, can be engineered to fight aging by eliminating senescent cells, offering a promising single-dose, lifelong treatment against aging-related diseases.
The fountain of youth has eluded explorers for ages. It turns out the magic anti-aging elixir might have been inside us all along.
Cold Spring Harbor Laboratory (CSHL) Assistant Professor Corina Amor Vegas and colleagues have discovered that T cells can be reprogrammed to fight aging, so to speak. Given the right set of genetic modifications, these white blood cells can attack another group of cells known as senescent cells. These cells are thought to be responsible for many of the diseases we grapple with later in life.
IceCure Medical, an Israeli company that developed a way to freeze and destroy tumors (cryoablation) as alternative to surgery, says an interim analysis of its current kidney cancer trial shows the platform is a safe and effective treatment for malignant renal tumors, with 89.5 percent recurrence-free rate.
The data from the analysis for the trial of the ProSense platform was presented at the Annual Israeli Conference on Interventional Radiology in Tel Aviv on June 10.
Cryoablation is not a new process, but IceCure’s system allows physicians to perform the procedure at their own office, with no need for hospitalization. It also uses liquid nitrogen instead of a mixture of argon and helium gasses, which is cheaper, can be frozen faster, and is easier to maintain at sub-zero temperatures, shortening the treatment time.
Physicists at the University of Vienna have experimentally measured the rotation rate of our planet using maximally path-entangled quantum states of light in a large-scale interferometer.

Grapene’s unusually high conductivity and favorable mechanical properties could further the development of flexible electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge.
In the journal Angewandte Chemie (“A Stretchable and Tough Graphene Film Enabled by Mechanical Bond”), a research team has now introduced a method to overcome this hurdle: they linked graphene nanolayers via “extendable” bridging structures.
Cartoon representations of the fabrication process of RBG films and toughening mechanism of mechanical bond. Upon applied force, the hidden chain of [2]rotaxane was released due to intramolecular motion, resulting in an increased interlayer slip distance. It follows that the mechanical performance of RBG films were improved when mechanical bond was introduced.
