In work that has been 30 years in the making, mathematicians have proved a major part of a profound mathematical vision called the Langlands program.
We’re joined by Dr. Denis Noble, Professor Emeritus of Cardiovascular Physiology at the University of Oxford, and the father of ‘systems biology’. He is known for his groundbreaking creation of the first mathematical model of the heart’s electrical activity in the 1960s which radically transformed our understanding of the heart.
Dr. Noble’s contributions have revolutionized our understanding of cardiac function and the broader field of biology. His work continues to challenge long-standing biological concepts, including gene-centric views like Neo-Darwinism.

Following the accelerated expansion discovery of the Universe, scientists introduced dark energy concepts, which faced issues like the cosmological constant problem.
Researchers at IKBFU developed a holographic dark energy model based on quantum gravity, which views the Universe as a hologram. This model, initially unstable, was refined to treat dark energy as perturbations, stabilizing it. It is now being tested against observational data for accuracy.
Discovery of Accelerated Universe Expansion.
A team of US-based researchers has developed an inexpensive and ultrathin metasurface that, when paired with a neural network, enables a conventional camera to capture detailed hyperspectral and polarization data from a single snapshot.
Inexpensive metasurface could revolutionize the capabilities of conventional imaging systems.

A UWE Bristol researcher hopes to revolutionise the jewellery industry and its supply chains with the creation of unique gemstone and jewellery designs with ground-breaking properties — including the world’s first single stone glow-in-the-dark manmade crystal.
For the last three years, award-winning jewellery designer Sofie Boons, who’s a Crafts Council Research Fellow at the university’s Centre for Print Research (CFPR), has been undertaking tests on the viability, limitations and use of innovative and experimentally grown crystals in the production of contemporary jewellery.
Adrenergic receptors (ARs) are preferentially expressed by innate lymphocytes such as natural killer (NK) cells.
Here, we study the effect of epinephrine-mediated stimulation of the β2-adrenergic receptor (β2AR) on the function of human NK cells.
β2-Adrenergic receptor stimulation inhibits NK cell activation. (A) β2-Adrenergic receptor expression analysis of PBMCs by flow cytometry (n = 8). Subsets were assigned according to the following markers: B cells (CD19+), NK cells (CD56+, CD3−), CD56 dim (CD56dim, CD3−), CD56 bright (CD56bright, CD3−), NK-T cells (CD56+, CD3+), T cells (CD3+), and monocytes (FSC/SSC). (B) Representative β2-adrenergic receptor (β2AR) expression histograms of freshly isolated or cultured NK cells. © IFNγ secretion of fresh NK cells (top) or cultured NK cells (bottom). NK cells were pretreated with epinephrine ± propranolol (each 1 µM) and stimulated for 5 h by plate-bound antibodies as indicated. Supernatant was analyzed by IFNγ ELISA (mean, n = 3). (D) Degranulation of fresh NK cells (top) or cultured NK cells (bottom) was analyzed by CD107a expression. NK cells were pretreated and stimulated (3 h) like in ©, (mean, n = 3). Statistical analysis in © and (D) was performed using two-way ANOVA test, **** p < 0.0001; *** p < 0.001; ** p < 0.01; control set to 100%).
A new study led by Stanford Medicine scientists found that certain changes in neural activity predicted which patients would benefit from a type of cognitive behavioral therapy.
