String theory and M theory part 1
Here I discuss two experiment and Gluon plasma, Gluon dipole. My lectures note is taken from professor Leonar Suskind string theory books and his lecture series. Professor Leonard Suskind books and his lecture grow my string theory knowledge. I have great respect🙏 to him. My main target to grow curiosity on science.

Time is a Processing Delay
I show how the time dilation derived in special relativity by assuming an abstract concept of malleable time, can be derived in a more mechanistic manner by assuming that the cosmos is like a simulation \& time is a processing delay.
I had this idea while playing minecraft with my son — every time I approached a large villager-town the PC slowed down and I thought \.
Generation Ships — The Hardest Part Is Not Distance
Could a generation ship actually stay alive long enough to cross interstellar space?
This video treats the generation ship as a closed-world survival problem, not as a simple starship fantasy. Distance matters, but the deeper challenge is whether air, water, food, spare parts, radiation shielding, population health, institutions, and culture can survive for centuries inside one sealed system.
The question is not only whether a ship can arrive. It is whether the human world inside it can remain repairable, governable, stable, and alive across generations that never chose the mission themselves.

Meet EcoBOT: The Autonomous Lab Standardizing Plant-Microbe Research
To harness biological systems (plants and microbes) for next-generation energy production and advanced materials, researchers are looking to beneficial plant-microbe interactions. Because these are complex systems, it has proven difficult to reproducibly control exactly which microbes are present. And, subtle differences in materials, methods, or even the hands of the researchers themselves can lead to inconsistent results. This makes it difficult to replicate previous work, significantly slowing the leap from scientific discovery to practical application.
Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) are overcoming this bottleneck by addressing a multi-layered challenge: building reliable physical hardware, engineering accurate visual sensors, and developing predictive algorithms. Their solution, EcoBOT, stands out from typical plant phenotyping facilities by integrating these distinct components into a reliably automated workflow under strictly sterile conditions.
EcoBOT takes specialized growth chambers, called EcoFABs, and integrates them with machine-learning tools that autonomously guide the discovery cycle. This system uses advanced imaging to regularly scan the entire plant—from the tips of its leaves to the bottom of its roots. By using Gaussian Process models and AI analysis tools, it can quickly analyze and model this visual data to calculate the most informative next steps. This directs the automated hardware to determine exactly how plants adapt to environmental stressors, establishing the crucial microbe-free baseline needed to eventually study plant-microbe interactions and engineer better bioenergy crops.
Graphene can hold multiple states of superconductivity, a new study finds
The researchers discovered the multiple superconducting states in atomically thin exfoliations of graphite, known as graphene. Specifically, graphene is a single-atom-thin sheet of carbon atoms arranged precisely in a microscopic lattice. The team made its discoveries in samples of rhombohedral graphene, which is a natural structure within graphite consisting of a stack of four or five graphene layers.
Interestingly, the researchers found that several of the new superconducting states in rhombohedral graphene are able to persist in the presence of a magnetic field, which normally kills superconductivity.
And in a further surprise, these superconducting states even get stronger when exposed to a magnetic field.
Scientists discover an unexpected way to make pancreatic cancer cells self-destruct
Researchers tested experimental PCAI compounds against pancreatic cancer cells and found they had powerful anticancer effects. One leading compound blocked more than 90% of cancer cell migration, suggesting it could help prevent the spread of tumors. Rather than suppressing cancer signaling, the treatment hyperactivated key pathways until the cells essentially self-destructed.
Mpox (Monkeypox) Virus and Its Co-Infection with HIV, Sexually Transmitted Infections, or Bacterial Superinfections: Double Whammy or a New Prime Culprit?
Epidemiologic studies have established that mpox (formerly known as monkeypox) outbreaks worldwide in 2022–2023, due to Clade IIb mpox virus (MPXV), disproportionately affected gay, bisexual, and other men who have sex with men. More than 35% and 40% of the mpox cases suffer from co-infection with HIV and sexually transmitted infections (STIs) (e.g., Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, and herpes simplex virus), respectively. Bacterial superinfection can also occur. Co-infection of MPXV and other infectious agents may enhance disease severity, deteriorate outcomes, elongate the recovery process, and potentially contribute to the morbidity and mortality of the ensuing diseases. However, the interplays between MPXV and HIV, bacteria, other STI pathogens and host cells are poorly studied.
