The Nobel Prize in Physics 2022

Alain Aspect, John Clauser and Anton Zeilinger have each conducted groundbreaking experiments using entangled quantum states, where two particles behave like a single unit even when they are separated. Their results have cleared the way for new technology based upon quantum information.

The Nobel Prize in Physiology or Medicine 2022

Humanity has always been intrigued by its origins. Where do we come from, and how are we related to those who came before us? What makes us, Homo sapiens, different from other hominins?

Through his pioneering research, Svante Pääbo accomplished something seemingly impossible: sequencing the genome of the Neanderthal, an extinct relative of present-day humans. He also made the sensational discovery of a previously unknown hominin, Denisova. Importantly, Pääbo also found that gene transfer had occurred from these now extinct hominins to Homo sapiens following the migration out of Africa around 70,000 years ago. This ancient flow of genes to present-day humans has physiological relevance today, for example affecting how our immune system reacts to infections.

Pääbo’s seminal research gave rise to an entirely new scientific discipline; paleogenomics. By revealing genetic differences that distinguish all living humans from extinct hominins, his discoveries provide the basis for exploring what makes us uniquely human.

Information access equality on generative models of complex networks

Applied Network Science volume 7, Article number: 54 (2022)

It is well known that networks generated by common mechanisms such as preferential attachment and homophily can disadvantage the minority group by limiting their ability to establish links with the majority group. This has the effect of limiting minority nodes’ access to information. We present the results of an empirical study on the equality of information access in network models with different growth mechanisms and spreading processes. For growth mechanisms, we focus on the majority/minority dichotomy, homophily, preferential attachment, and diversity. For spreading processes, we investigate simple versus complex contagions, different transmission rates within and between groups, and various seeding conditions. We observe two phenomena. First, information access equality is a complex interplay between network structures and the spreading processes. Second, there is a trade-off between equality and efficiency of information access under certain circumstances (e.g., when inter-group edges are low and information transmits asymmetrically). Our findings can be used to make recommendations for mechanistic design of social networks with information access equality.

Postdoctoral Fellowship at NAS, Mahidol University in Nakhonsawan, Thailand

Centre for Theoretical Physics and Natural Philosophy (NAS) would like to invite applications for two postdoctoral positions.

One position will be in cosmology with a particular focus on dark energy and modified gravity models. The candidate should have a PhD in either physics or in astrophysics with strong expertise and knowledge in both the theoretical and observational aspects of cosmology.

Another position will be offered in complexity. The candidate should have a PhD in Physics with a prior experience in time series and network analysis together with a strong practical programming skill in statistical and/or machine learning data analysis.

Initially, the position will be offered for one year and can be extended for two more years. Upon satisfactory performance, it may lead to a tenure track position.
