[1] Geoscience: No glacier melt in a greater Himalaya mountain range

DOI: 10.1038/ngeo1450

Glaciers in the Karakoram mountain range, located at the intersection of China, India and Pakistan, have been stable despite global mass loss of mountain glaciers. The research, published online this week in Nature Geoscience, reports that the anomalous behaviour of glaciers in this particular mountain range emphasizes the local differences between glaciers, as substantial ice loss has been detected in the neighbouring Himalaya range.

Julie Gardelle and colleagues calculated the differences between two digital elevation maps, taken in 2000 and 2008. They assess about one quarter of the region of the Karakoram range, and find that glaciers gained a small amount of mass over that period. Anomalous behaviour of the Karakoram glaciers had been suspected but not confirmed with measurements, owing to the inaccessibility of the terrain.

In an accompanying News and Views article, Graham Cogley suggests that if the mass balance measurements reported in this study are representative for all the Karakoram glaciers, ice loss in this region contributed less to sea-level change in the past decade than implied by a previous estimate.

[2] Nature: Treatment-resistant acute myeloid leukaemia mutants

DOI: 10.1038/nature11016

A mutation frequently seen in acute myeloid leukaemia (AML), a form of blood cancer, is established as a viable therapeutic target in a subset of AML cases in this week’s Nature. The mutated gene encodes an activated version of a protein called FLT3, which is normally involved in the generation of blood cells. Secondary mutations in FLT3 are shown to cause resistance to AML treatment.

Activating mutations in the FLT3 gene are found in about 20% of AML patients and are associated with poor prognosis. Whether these mutations are drivers of disease has been unclear, but Neil Shah and colleagues demonstrate that FLT3 mutations may have a causal role in AML development. They discover secondary FLT3 mutations in a small group of AML patients that confers resistance to AC220, an FLT3-inhibiting drug currently being evaluated for the treatment of AML. This finding suggests that further research is needed to develop novel drugs that can target FLT3 with secondary mutations, the authors conclude.

[3] Climate Change: Renewable energy costs in developing countries

DOI: 10.1038/nclimate1490

A more fine-grained bottom-up approach to climate change can identify important climate variations across countries as well as what technologies would help in meeting emission-reduction goals, reports a paper published this week in Nature Climate Change.

At the 2010 Cancún meeting on climate change, nations agreed on a number of new mechanisms — such as the Green Climate Fund — to support financially the greenhouse-gas emissions abatement efforts of developing countries. Renewable energy technologies have a great role to play, but the discussion about their adoption in developing countries is traditionally informed by highly aggregated top-down cost analyses that hide important cross-country differences.

Tobias Schmidt and colleagues estimated the costs of photovoltaic (PV) and wind energy technologies in six very different developing countries: Brazil, Nicaragua, Egypt, Kenya, India and Thailand. With their detailed bottom-up approach, they estimated that PV electricity costs are by far larger than wind costs in all countries (between 2.2 to 4.5 times in 2010) and are likely to remain so at least until 2020 (between 1.7 and 3.4 times). However, the incremental electricity cost of wind (the cost of wind energy minus the cost of baseline energy) varies significantly across countries. In particular, it is very high in Brazil, India and Thailand, much lower in Egypt and negative in Kenya and Nicaragua where the high baseline costs by far exceed the costs of wind. The authors emphasize the importance of a fair methodology to calculate the incremental costs, which ideally should exclude fossil-fuel subsidies from the baseline.

In light of the country–technology patterns identified, the researchers discuss the best approaches to scale-up renewable technologies. They suggest that large developing countries with good institutional capacities should rely on nationally appropriate mitigation actions to address country–technology combinations through technology-specific feed-in tariffs on a national level. In contrast, small countries are more likely to succeed under a reformed Clean Development Mechanism.

[4] Photonics: Electrically driven single-photon source at room temperature

DOI: 10.1038/nphoton.2012.75

Electrically driven single-photon generation at room temperature is reported in Nature Photonics this week. The work could help realize practical quantum communications schemes such as quantum cryptography and quantum computing.

Today’s single-photon-generating schemes are either optically driven at room temperature or electrically driven at cryogenic temperatures. Norikazu Mizuochi and colleagues achieve the best of both — room-temperature electrically driven operation — by exploiting an impurity-free region in a diamond diode. The device is capable of generating 40,000 photons per second at an injection current of 14 milliamperes, which is comparable to the driving current of commercially available light-emitting diodes.

[5] Chemistry: 3D printing for custom chemistry

DOI: 10.1038/nchem.1313

The use of 3D printing to create tailor-made containers for chemical reactions is reported online in Nature Chemistry this week. This technique puts the design, construction and operation of custom labware under digital control and offers researchers rapid access to almost any reaction vessel they can imagine.

Leroy Cronin and colleagues use a relatively low-cost commercially available 3D printing platform with open-source design software to produce a range of what they call ‘reactionware’. The basic material used to make the reactionware is simply a bathroom sealant, which is a quick-setting polymer, but additional components — such as observation windows or electrodes — can be incorporated during the printing process. Catalysts can also be printed into the walls of the reactionware to create reactors that actively participate in chemical reactions, something that is not possible with traditional labware.

In an accompanying News & Views article, R. Daniel Johnson says that, “One promising aspect of this idea is that 3D printing enables the rapid preparation of complex reactor systems that would not otherwise be readily accessible.”

The neural underpinnings of social behaviour are discussed in a special collection of review and opinion articles published this week in Nature Neuroscience.

In a pair of complementary perspective articles, Naomi Eisenberger and Andreas Meyer-Lindberg describe the cross-talk between social factors in everyday life and physical and mental health, respectively: social disconnection and stress is associated with more bodily illness, as well as a higher risk for disorders such as schizophrenia. However, the brain is an extremely plastic organ, and in their piece, Richard Davidson and Bruce McEwen review how interventions such as meditation are likely to result in brain plasticity associated with positive outcomes. They also look at animal work suggesting that both positive and negative factors can result in structural and functional changes in the brain.

Other articles in the special issue review how hormones such as oxytocin and testosterone modulate social behaviors ranging from friendliness to aggression in both animals and humans, and a critical review of studies of how the brain produces empathy, the ability to feel what another person is feeling, amongst other topics.
