Dark energy, which drives the accelerated expansion of the Universe, is assumed to be constant since the Universe began by today’s leading model. Researchers from Japan, Spain, and the U.S. explored the possibility of time-varying dark energy by conducting one of the largest cosmological simulations to date. Their results show that while dark energy variations have modest effects alone, variations in other parameters like matter density significantly alter galaxy formation and cosmic structure, aligning closely with the latest observations.

Precise heating, ventilation, and air conditioning (HVAC) control is important for energy savings in residential buildings. Recently, a team of researchers from Korea, led by a scientist from Hanbat National University, has demonstrated a quantum reinforcement learning based HVAC control system for the first time. It provides significant improvements over traditional technologies in power consumption and electricity costs, simultaneously ensuring maximum occupant comfort.

The demand for polymer-based dielectrics with a low dielectric constant and a low dissipation factor is rising, owing to the expansion of 5G and 6G telecommunications networks. However, polymer designs that satisfy both requirements have been difficult to realize. Now, researchers from Japan have developed a new family of ultralow dielectric loss polymers, presenting a new strategy for developing next-generation dielectrics that are suitable for future beyond-6G telecommunications.

Researchers at Integra Therapeutics, in collaboration with the Pompeu Fabra University (UPF) Department of Medicine and Life Sciences (MELIS) and the Center for Genomic Regulation (CRG), have designed and experimentally validated new synthetic proteins that can edit the human genome more efficiently than proteins provided by nature. This work, a global pioneer published today in the journal Nature Biotechnology, will be of great use in improving the current gene editing tools used in biotechnology research and personalized medicine by developing cellular (CAR-T) and gene therapies, especially to treat cancer and rare diseases.

A landmark study conducted by The Hong Kong University of Science and Technology (HKUST) has demonstrated that a genetic variant, TREM2 H157Y, significantly increases the risk of Alzheimer’s disease (AD) in individuals of ethnic Chinese descent. The research reveals that this variant confers a risk level comparable to that of the strongest known genetic risk factor for AD, APOE-ε4, and is associated with more rapid clinical progression and more severe neurodegeneration.A landmark study conducted by The Hong Kong University of Science and Technology (HKUST) has demonstrated that a genetic variant, TREM2 H157Y, significantly increases the risk of Alzheimer’s disease (AD) in individuals of ethnic Chinese descent.
