LGBTSTEM DAY – 5 July 2018

Pride in STEM, House of STEM, and InterEngineering are proud to announce the launch of the first ever International Day of LGBT+ people in Science, Technology, Engineering, and Maths, called LGBTSTEM Day, to be celebrated on 5 July 2018.



The purpose of LGBTSTEM Day is to improve the visibility and representation of LGBT+ people in STEM, help them access and share resources, and build a stronger LGBT+ community.


The LGBT+ Physical Sciences Network, formed in 2016 by the Royal Astronomical Society and the Institute of Physics, support LGBTSTEM Day and will contribute to the event in a number of ways.


The LGBT+ Physics Sciences Network, with the Royal Astronomical Society, believe that professional membership organisations can offer support and experiences of current good practice with regard to successful LGBT+ networks in places of work and study. Facilitating and helping to connect the LGBT+ physical sciences community is an important step in this process and we believe that LGBTSTEM Day will enable this.

New study helps explain Greenland glaciers’ varied vulnerability to melting

Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.

Identification of facies-controlled eogenetic karstification in the Upper Cretaceous of the Halfaya oilfield and its impact on reservoir capacity

Penecontemporaneous dissolution has been considered as the dominant origin of reservoir formation, whereas epigenetic dissolution has also played certain roles in the improvement of reservoir capacity in the Upper Cretaceous Mishrif Formation in the Middle East. Here, we report a possible new reservoir origin based on a case study in the Halfaya oilfield of Iraq, that is, facies-controlled eogenetic karstification. The most representative evidence is that early selective dissolution is not only present in relative high-energy categories of rocks but also in low-energy ones in the cored intervals. Meanwhile, the occurrence frequency of karstification varies among different environments and associated lithologies. In grainstones and packstones, spongy-like dissolution pores and irregular karst channels are widely developed, with fillings and massive plastic breccias. In contrast, in wackestones, lots of high-angle karst channels are developed based on biological burrows, and the karst is more frequently observed in the shoal environment than in the low-energy environments. These characteristics are indication of eogenetic karstification. The model of this karstification can be attributed to a multiple superimposition of short-term exposure during the penecontemporaneous stage and the medium-term exposure after the shallow burial stage. The karst has impact on reservoir capacity, according to which 3 areas are divided in the increasing order, namely, the tight bedrock area, spongy-like dissolution pores area, and karst channels and vugs-filled area, among which the karst channels and vugs-filled area is the most favourable for oil accumulation. This understanding might be general to the Mishrif reservoirs in the entire Middle East.

Depositional settings and changing composition of the Jambi palaeoflora within the Permian Mengkarang Formation (Sumatra, Indonesia)

The Merangin River section in Sumatra exposes the Permian Mengkarang Formation. This is composed of eight intervals showing upwards fining and thinning of volcanic tuffs and volcaniclastic sedimentary rocks, overlain by their reworked alluvial products. Isotopic age evaluation of the top and the base of the Merangin section indicates an average duration of 630,000 years (from 296.77 ± 0.04 to 296.14 ± 0.09 Ma). Extrapolation of the eight intervals onto neighbouring tributaries by using earlier geological studies and the strike of the beds allows for the integration of the data assembled in recent expeditions, and those from 1925, leading to the lithostratigraphic assignment of more than 2,000 palaeobotanical specimens. The compilation of all assembled palaeobotanical data indicates there is a change in composition from a palaeoflora dominated by Cordaites, ferns, or club mosses to one in which seed ferns were dominant. These changes, coupled to eustatic sea-level fluctuations, indicate a climatic origin for this transition and extend palaeofloral trends perceived earlier in Far Western low latitudes to the Far Eastern Palaeotethys.

Geochemistry of high-Nb basalt-andesite in the Erguna Massif (NE China) and implications for the early Cretaceous back-arc extension

This paper presents new zircon laser ablation–inductively coupled plasma–mass spectrometry U–Pb age and whole-rock geochemical data for the high-Nb basalts-andesites (HNBs) from the Meiletu Formation in NE China. In comparison with common arc basalts and Nb-enriched basalts, the Meiletu HNBs (140 Ma) show high TiO2 (1.7–3.2 wt.%), P2O5 (0.7–1.7 wt.%), Nb (14.6–34.0 ppm), and Zr (314–600 ppm) contents, and high (Nb/Th)PM (0.26–0.91), (Nb/La)PM (0.22–0.36), Nb/U (8.2–24.8) ratios. They show strongly light rare earth element (REE) enriched chondrite-normalized REE patterns with unusually high total REE contents [(TREE)cn = 978–1802]. Unlike adakite-associated HNBs derived from a mantle wedge metasomatized by adakites, the Meiletu HNBs were derived from low degree (80 km). The Meiletu HNBs were generated in an intracontinental back-arc extension setting. Combined with previous geological observations, it is argued that Early Cretaceous tectonics of the Erguna Massif is dominated by the Mongol–Okhotsk oceanic slab-rollback and back-arc extension.

Underwater volcano behavior captured by timely scientific expedition

Researchers got a rare opportunity to study an underwater volcano in the Caribbean when it erupted while they were surveying the area. The research, published online in the journal Geochemistry, Geophysics, Geosystems, a journal of the American Geophysical Union, provides new insight into the little-studied world of underwater volcanoes. It investigated a volcano named Kick-‘em-Jenny (KeJ), which is thought to be named after the turbulent waters nearby.

Professor Stephen Hawking CH CBE FRS FRSA, 1942-2018

The Royal Astronomical Society offers its condolences to the family of Professor Stephen Hawking CH CBE FRS FRSA, whose death was announced today.

Credit: NASAOver six decades, Professor Hawking carried out ground-breaking work in cosmology, seeking to understand the nature of black holes, and the origin and evolution of the universe as a whole. He conveyed these ideas to a wide audience through books, broadcasting and public engagement. At the same time Hawking suffered from amyotrophic lateral sclerosis (ALS), which saw him confined to a wheelchair for much of his life, and he famously communicated through an electronic speech generation device.


Hawking received many awards over his lifetime. The Royal Astronomical Society awarded him the Eddington Medal in 1975 and its Gold Medal in 1985. He was one of the youngest scientists to be elected a Fellow of the Royal Society (FRS) in 1974, and was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009.


Professor John Zarnecki, the President of the Royal Astronomical Society, commented: “Few scientists will ever capture the imagination of the public in the way that Stephen Hawking did. He will be remembered for his extraordinary scientific vision, his huge profile, and the way he transcended his physical disabilities. With his death, we have lost a huge figure in astrophysics and cosmology, and one who will be remembered far into the future.”


Phil Diamond, Executive Director of the Royal Astronomical Society added: “Stephen Hawking was a cult figure to those of us who were geeks studying physics in secondary school in the 70s. And he was funny too. I remember a BBC Horizon documentary filming a seminar of Stephen with his graduate students. My friend, Chris Hull, then his PhD student, now a Professor of Theoretical Physics himself, held up a toilet roll in order to represent a particularly simplified model of the universe. Hawking’s voice could be heard telling him that it was the wrong way up.

‘Then, in the 80s, ‘A Brief History of Time’ came out. Suddenly our best kept secret was shared with the world. What a wonderful phenomenon that was, and a huge benefit to physics and cosmology. We had our own superstar, the public really ‘got’ him, and he started the cultural revolution allowing ‘clever’ to be cool.  

What a brave, brilliant, remarkable man. We were lucky to have him.”

Constraining the denudation process in the eastern Sichuan Basin, China using low-temperature thermochronology and vitrinite reflectance data

The temperature history of samples and maximum palaeogeothermal profiles of boreholes were reconstructed based on low-temperature thermochronology and vitrinite reflectance data, and the results provide limits for the timescale and amount of uplift–denudation of the eastern Sichuan Basin. The thermal history showed that the uplifting and cooling of eastern Sichuan Basin began around the Late Cretaceous (approximately 100–80 Ma). The region had experienced a continuous cooling process from the Late Cretaceous until the present, with the geothermal gradient decreasing from 32–36 °C/km to 20–23 °C/km. The amount of denudation at the Puguang region in north-eastern Sichuan was approximately 2.3 km, whereas that at south-eastern Sichuan was 1.9 km, and the erosion thickness in the eastern Sichuan fold belt that was revealed via the field samples is 2.3 ± 0.3–2.6 ± 0.3 km. The north-eastern Sichuan experienced sustained cooling with inconspicuous fluctuations, whereas the thrust belt and the south-eastern Sichuan Basin presented 2–4 stages with different cooling rates. It may indicate that the eastern Sichuan fold belt experienced a complex structural evolution, characterized by episodic upliftings and deformations since Late Cretaceous, while a different and gentle deformation took place in the northeastern Sichuan Basin.

How much snow accumulates in North America each year? More than scientists thought

There’s a lot more snow piling up in the mountains of North America than anyone knew, according to a first-of-its-kind study. Scientists have revised an estimate of snow volume for the entire continent, and they’ve discovered that snow accumulation in a typical year is 50 percent higher than previously thought.
