Radiation damage is the most fundamental limitation for achieving high resolution in electron cryo-microscopy (cryo-EM) of biological samples. The effects of radiation damage are reduced by liquid-helium cooling, although the use of liquid helium is more challenging than that of liquid nitrogen. To date, the benefits of liquid-nitrogen and liquid-helium cooling for single-particle cryo-EM have not been compared quantitatively. With recent technical and computational advances in cryo-EM image recording and processing, such a comparison now seems timely. This study aims to evaluate the relative merits of liquid-helium cooling in present-day single-particle analysis, taking advantage of direct electron detectors. Two data sets for recombinant mouse heavy-chain apoferritin cooled with liquid-nitrogen or liquid-helium to 85 or 17 K were collected, processed and compared. No improvement in terms of resolution or Coulomb potential map quality was found for liquid-helium cooling. Interestingly, beam-induced motion was found to be significantly higher with liquid-helium cooling, especially within the most valuable first few frames of an exposure, thus counteracting any potential benefit of better cryoprotection that liquid-helium cooling may offer for single-particle cryo-EM.

This paper recounts the first successful cryo-cooling of protein crystals that demonstrated the reduction in X-ray damage to macromolecular crystals. The project was suggested by David C. Phillips in 1965 at the Royal Institution of Great Britain and continued in 1967 at the Weizmann Institute of Science, where the first cryo-cooling experiments were performed on lysozyme crystals, and was completed in 1969 at Purdue University on lactate dehydrogenase crystals. A 1970 publication in Acta Crystallographica described the cryo-procedures, the use of cryo-protectants to prevent ice formation, the importance of fast, isotropic cryo-cooling and the collection of analytical data showing more than a tenfold decrease in radiation damage in cryo-cooled lactate dehydrogenase crystals. This was the first demonstration of any method that reduced radiation damage in protein crystals, which provided crystallographers with suitable means to employ synchrotron X-ray sources for protein-crystal analysis. Today, fifty years later, more than 90% of the crystal structures deposited in the Protein Data Bank have been cryo-cooled.

Cryocooling for macromolecular crystallography is usually performed via plunging the crystal into a liquid cryogen or placing the crystal in a cold gas stream. These two approaches are compared here for the case of nitro­gen cooling. The results show that gas stream cooling, which typically cools the crystal more slowly, yields lower mosaicity and, in some cases, a stronger anomalous signal relative to rapid plunge cooling. During plunging, moving the crystal slowly through the cold gas layer above the liquid surface can produce mosaicity similar to gas stream cooling. Annealing plunge cooled crystals by warming and recooling in the gas stream allows the mosaicity and anomalous signal to recover. For tetragonal thermolysin, the observed effects are less pronounced when the cryosolvent has smaller thermal contraction, under which conditions the protein structures from plunge cooled and gas stream cooled crystals are very similar. Finally, this work also demonstrates that the resolution dependence of the reflecting range is correlated with the cooling method, suggesting it may be a useful tool for discerning whether crystals are cooled too rapidly. The results support previous studies suggesting that slower cooling methods are less deleterious to crystal order, as long as ice formation is prevented and dehydration is limited.

New world megafauna such as mammoths, bison and camelids that were alive at the end of the Pleistocene epoch (some 13,000 years ago) would have produced massive amounts of methane-rich flatulence and belching, thanks to the cellulose-digesting microbes in their guts.

Using ???cool??? materials to construct roads and walkways is an effective way of lowering urban temperatures to make cities more comfortable in hot weather. According to a recent study, surface temperatures were reduced by 12??C and ambient temperatures were reduced by 1.9??C after cool pavements were installed in a city park in Greece.

Covering walls with plants can significantly reduce the temperature of building walls during hot summer months. A recent study of three different types of these ???living walls??? in Italy suggests that they can be 20??C cooler than a bare wall on sunny days. An added advantage is that living walls can be retrofitted to existing buildings.

The discomfort associated with hot, dry summers in some urban areas can be reduced by planting the most appropriate trees in open city spaces, according to a recent study. The researchers identified the Indian laurel fig as the most effective tree for this purpose in the Greek city of Chania.

During heatwaves, forests initially have a warming effect on surrounding air temperatures. However, in the longer-term they have a cooling impact, according to a recent study. This new information about plant contributions to temperatures will help further improve climate modelling.

Trees and other vegetation have an important influence on urban temperatures. To explore these effects, Japanese researchers have built and studied scale models of tree-lined streets. This approach could help designers and planners create urban environments that are cooler during summer months.

The available and emerging renewable technologies suitable for urban environments have been assessed in a recent study. Wind and solar technology can now be integrated into building design, and smart grids and metering can more efficiently manage energy production and demand at a local level. Investing in community-level renewable-energy projects can, therefore, help meet the future energy needs of towns and cities.

The urban heat island (UHI) effect can be completely offset by using 'cool' and 'green' roofs, finds new research from the US. However, the study also found that different roofs may affect rainfall and energy demand, and that their efficiency varies with location.

Which types of buildings will require the least energy for heating and cooling under climate change? A study in Vienna, Austria, looked at the balance between heating and cooling demand in four different types of buildings. The research provides a method that could be useful for other European cities trying to adapt to climate change.

Cool pavements, which can be used to reduce the Urban Heat Island (UHI) effect, where towns and cities are warmer than surrounding rural areas, have been reviewed in new research. The review found that reflective pavements can reduce temperatures by up to 20°C and are more durable than evaporative pavements, which are less effective at temperature reduction but may have other benefits, such as reducing runoff.

A new study based on high-resolution satellite observations of forests suggests the 'albedo', or reflectivity, of a forest needs to be carefully considered in afforestation schemes designed to mitigate climate change, i.e. carbon balance alone is not a good indicator of mitigation value. The authors argue that the Kyoto Protocol carbon accounting rules grossly overestimate the cooling caused by afforestation, because they do not consider albedo effects.

Pioneering methods used in the Netherlands combine remediation of brownfield sites with the use of groundwater for heat cold storage (HCS, or ATES: Aquifer Thermal Energy Storage) to achieve both low-cost remediation and sustainable use of energy.

A case study in Sweden has shown that critically endangered European eels are being lost when they are sucked into the local nuclear power station???s cooling system. A process to pump the eels back into the sea could be beneficial to this species, the researchers conclude.

A new study suggests that widespread adoption of hydrogen fuel could have major benefits for tackling climate change and air pollution. The researchers modelled the impacts of replacing petrol with hydrogen as a fuel for cars and claim their methods, which employ a new modelling tool, could be useful in planning and policymaking.

The net cooling effect that aerosols have on the climate will be lost as emissions drop in the future, new research suggests. However, the consequent warming will ultimately be counter balanced if policies to reduce greenhouse gas (GHG) emissions are put in place.

Researchers have published a paper providing evidence that a ‘cooling-off effect’ can lead to increased public acceptance of new environmental technologies over time. The scientists analysed survey results from over 1 000 respondents in Germany, using solar radiation management (SRM), a controversial climate-engineering technique, as a test case. They found that, following a cooling-off period of either one month, 12 months, or 18 months, acceptance of SRM increased significantly — and that the longer the cooling-off period, the larger the increase. These findings have far-reaching implications, both for the deployment of SRM and for climate policymakers seeking to more accurately measure the public acceptability of novel interventions.
