Cells from the centre of tumours most likely to spread around the body
Researchers from the Francis Crick Institute, Royal Marsden, UCL and Cruces University Hospital have found that cells from different parts of kidney tumours behave differently, and surprisingly, cells within the centre of a tumour are the most aggressive and have the highest chance of spreading around the body.

The perfect blend: Optimizing gas mixtures for hydrogen storage in clathrate hydrates
In a recent study, Dr. Park's group explored a feasible solution to the problem of using clathrate hydrates as vessels for H2 storage. However, the enclathration of pure H2 is still a slow process. To improve upon this strategy, the team set out to find the best hydrogen-natural gas blend (HNGB) for the energy-efficient formation of clathrate hydrates. They carefully analyzed the clathrate formation kinetics and structure and the distribution of trapped molecules.

Anisotropic zoning in the upper crust of the Tianshan Tectonic Belt
Tianshan Tectonic Belt is a major seismic activity belt in the western part of the Chinese mainland. A recent study revealed the anisotropic zoning in the upper crust of the Tianshan tectonic belt, The polarization directions of the fast waves in most of the study area are consistent with the local tectonic stress fields, the time delays share an increasing trend from east to west in the NorthTianshan and South Tianshan Mountain ranges.

Scientists explain why climate models can't reproduce the early-2000s global warming slowdown
The unexpected global warming slowdown during 1998-2013 challenges the simulation ability of climate models since most models participating in phase 5 of the Coupled Model Intercomparison Project (CMIP5) cannot simulate it. The CMIP6 with the most advanced climate models is now underway. Researchers evaluated the ability of the new-generation CMIP6 climate models on simulating the warming slowdown, and further revealed the reasons for the dilemma of slowdown simulation.

Greenland becoming darker, warmer as its snow ages and changes shape
A reduction in the amount of fresh, light-colored snow in parts of Greenland is exposing older, darker snow. The research reports on new weather patterns and explains how the changing shape of snowflakes on the surface is leading to conditions on Greenland's ice sheet, including possibly increased melting.

Fast, affordable solution proposed for transparent displaysand semiconductors
The Korea Institute of Machinery & Materials(KIMM) developed a roll-based damage-free transfer technique that allows two-dimensional (2D) nanomaterials to be transferred into wafer scale without damage. The proposed technique has a variety of applications from transparent displays and semiconductors to displays for self-driving cars, and is expected to accelerate the commercialization of 2D nanomaterial-based high-performance devices.

Mothers can influence offspring's height, lifespan and disease risk through mitochondria
Mitochondria - the 'batteries' that power our cells - play an unexpected role in common diseases such as type 2 diabetes and multiple sclerosis, concludes a study of over 350,000 people conducted by the University of Cambridge.The study, published today in Nature Genetics, found that genetic variants in the DNA of mitochondria could increase the risk of developing these conditions, as well influencing characteristics such as height and lifespan.

A connection between senescence and stem cells caused by a breast cancer-initiating protein
Researchers from the Spanish National Cancer Research Centre (CNIO) and the IDIBELL, led by Eva González-Suárez at the CNIO, have found that the hyperactivation of the RANK pathway plays a double function in breast cells: in the early stages of cancer, it activates senescence, which has a protective effect and delays the appearance of tumours; in more advanced stages, RANK-induced senescence favours the accumulation of stem cells, which promotes tumour growth and aggressiveness.

New technology converts waste plastics to jet fuel in an hour
Researchers have developed an innovative way to convert plastics to ingredients for jet fuel and other valuable products, making it easier and more cost effective to reuse plastics. The researchers in their reaction were able to convert 90% of plastic to jet fuel and other valuable hydrocarbon products within an hour at moderate temperatures and to easily fine-tune the process to create the products that they want.

Skoltech researchers developed an enriched method for increasing the capacity of next-generation metal-ion battery cathode materials
Scientists at Skoltech Center for Energy Science and Technology have developed an enriched and scalable approach for increasing the capacity of a broad range of metal-ion battery cathode materials. An important advantage of the approach is its scalability. The process requires no sophisticated conditions and is relatively safe. Additionally, the reducing agents can be recycled after they react with the cathodes because their redox chemistry is reversible. These features make the method promising for large-scale applications.

Climate policies, transition risk, and financial stability
The way in which banks react to climate risks and uncertainty could impact financial stability as well as the world's transition to a low-carbon economy. A new study by researchers from IIASA and the Vienna University of Economics and Business explored the role that banks' expectations about climate-related risks will play in fostering or hindering an orderly low-carbon transition.
