Dyckia semperflorens: A new species of Bromeliad from the cold region of Rio Grande do Sul, southern Brazil.

Bromeliads are herbaceous Monocotyledons native to the Americas (with a single species known from West Africa) and related to the Sedges and Grasses. They have a distinctive rosette shape, with blade-like leaves spiraling out from a central point. In some cases the centre of this rosette forms a water reservoir held in place by tightly overlapping leaf-bases, which can contain entire miniature ecosystems. Many Bromeliads are epiphytes, living on the branches of trees, particularly in rainforests, but others live on the ground and many are found in deserts.

The genus Dyckia contains 188 recognised species of Bromeliads, making it one of the most specious genera within the group. The majority of these are found in arid areas of Argentina, Bolivia, Paraguay, Uruguay, and Brazil, with about two thirds of all species being found in Brazil. Species of Dyckia tend to have spiny leaves and a succulent form, and often grow on thin soils or directly on rock. They also tend to be highly endemic, with most species having a limited geographical range, and several species known only from a single location.

In a paper published in the Nordic Journal of Botany on 17 October 2025, Henrique Mallmann Büneker and Jorge Ernesto de Araujo Mariath of the Laboratório de Anatomia Vegetal and Programa de Pós-graduação em Botânica at the Universidade Federal do Rio Grande do Sul, describe a new species of Dyckia from an escarpment beside the Rio dos Touros in the municipality if Bom Jesus in Rio Grande do Sul State, Brazil.

The new species is named Dyckia semperflorens, where 'semperflorens', means 'continuously flowering'; when the species was first observed in 2017 a live specimen was collected and brought to the Planeta Bromélia nursery in Porto Alegre, where it has remained in bloom ever since. Specimens of Dyckia semperflorens reach 65-96 cm in height, and have a rosette diameter of 38-65 cm. Leaves are 47-107 cm in length, with the inner leaves being semi-erect, while the outer ones are more relaxed, all have an elongate triangular shape with a waxy surface and sparse spines on the edges. Flowers are born on an erect or semi-erect peduncle, 20-36 cm in length. Flowers are tubular and greenish or reddish, flowers on the base of the peduncle are larger than those towards the tip.

Dyckia semperflorens is known from a single location, on a rocky escarpment along the banks of the Touros River, 1054 m above sealevel, in the municipality of Bom Jesus, Rio Grande do Sul State, in southern Brazil. The local environment is dominated by grassland, with patches of  Araucaria forest. The climate here is temperate, with frost and snowfall in the winter. 

The only known population of Dyckia semperflorens grows in an area currently under pressure from cattle grazing and frequent anthropogenic fires, which are used for grassland management in the region. However, there are other similar areas in the region which could potentially support the species, and which have not been explored yet, so Büneker and Mariath refrain from assigning a conservation status to the species at this time.

The Museum of West African Art Archaeology Project.

The city of Benin in southern Nigeria (not to be confused with the modern Benin) formed the capital of the Kingdom of Benin (or Edo) between about 1200 AD and 1897, when it was sacked and burned by a 'Punitive Expedition' led by Admiral Sir Harry Rawson. Following this event, loot taken from the city was sold by the officers involved to museums across Europe and North America, a group of artefacts known collectively as 'Benin Bronzes' due to the large amount of exquisite bronze-ware among the collections, although the term is used to refer to all looted items from this period, regardless of the material from which they were manufactured.

Gaining the return of these artefacts has been a long term goal for many people in Benin, and indeed Nigeria and the Nigerian diaspora, and many (though not all) western museums have agreed to return objects from their collections. To this end, in 2020 architect Sir David Adjaye was commissioned to design a museum in Benin to house those artefacts, a museum due to open on 11 November 2025, as the Museum of West African Art.

The museum has been built on a site previously occupied by a hospital built in the 1970s, and before that a police barracks from the early twentieth century. Before this, the area had been a part of the historic Palace Complex of Benin, with the clearing and excavation of this site for foundations creating the opportunity for the first major archaeological excavation in Benin for over 50 years.

To this end, the Museum of West African Art Archaeological Project was set up as a collaborative project between the Museum of West African Art, the British Museum, the National Commission for Museums and Monuments, the Cambridge Archaeological Unit, and Wessex Archaeology. This project involved the training and employment of ten early-career Nigerian archaeologists, who were given the opportunity to undertake placements in London, Cambridge and Cyprus, as well as 58 additional fieldwork roles.

In a paper published in the journal Antiquity on 23 October 2025, Caleb Folorunso of the Museum of West African Art and the University of Ibadan, Sam Nixon of the Department of Africa, Oceania and Americas at the British Museum, Segun Opadeji, also of the Museum of West African Art, Abidemi Babalola, also of the Department of Africa, Oceania and Americas at the British Museum, Charles Le Quesne, again of the Museum of West African Art, Anna Adamu of the National Commission for Museums and Monuments, Marcus Brittain and Matthew Brudenell, of the Cambridge Archaeological Unit at the University of Cambridge, and Chris Breeden of Wessex Archaeology, present the initial results of the archaeological work at the Museum of West African Art site.

Wider site context: (a) map of Museum of West African Art  Campus and excavation zones within Benin City; (b) Rainforest Gallery excavations in foreground and Institute building top left. Folorunso et al. (2025).

A series of pits at the site reached a maximum depth of 3.0 m, with straitified cultural layers reaching to depths of between 1.45 and 1.60 m. The oldest radiocarbon dates obtained came from the first millennium AD, although these were below any cultural layer. The main settlement layers begin in the mid fourteenth century, progress through a peak cultural stage in the sixteenth and seventeenth centuries, recording the palace through to its destruction in 1897, and above this layers associated with the colonial police barracks and post-colonial hospital.

The area excavated covered a large portion of the former complex, including the 'wives quarter' or erie, a zone formerly occupied by a number of shrines, as well as a number of other buildings recorded on nineteenth century maps. A number of walls and floors from the earliest phases of occupation were excavated and examined, with final phase, eighteenth and nineteenth century buildings following the same axis as earlier buildings, implying a continuity in urban planning. The wives quarter was surrounded by a substantial earthen wall and a large wooden gate, close to which was a 5 m pit, which may have served as a source of building material.

(2025).

The large excavated building contained substantial evidence of ritual activities at the site, including upturned pots, caches of Cowrie shells (also in pots), and moulded chalk arrangements, and is interpreted to have been a shrine. This building also contained over 100 glass bottles, most of which appear to have contained gin, with trade marks such as Africana, Van Hoytema, and Van Marken. These were found alongside Giant Snail shells and quantities of iron, making it likely that they were offerings at a shrine.

The excavations also uncovered evidence of artisanal activity, including pits containing charcoal and traces of metal slag, thought to date from the nineteenth century. Also found were pieces of crucibles and fragments of copper alloys, although these are still under investigation. Over 120 000 pieces of pottery and ceramics were unearthed, including imported glazed wares, although most were of local origin. Other finds included smoking pipes, beads, glass bottles and metal objects. The ceramic fragments appear to represent a sequence, which has the potential to be developed and applied to other sites, although this is also still being worked on. Plant remains include crops such as Oil Palm, Pearl Millet, Cotton, and Foxtail Millet. Many pollen samples have also been collected, which in combination have the potential to shed light on changing agricultural practices and diet over the history of the site.

Selected material culture: (a) metallurgy; (b) other finds. Folorunso et al. (2025).

Post 1897 finds at the site include a European cemetery, believed to have been founded shortly after the fall of the city and now mapped for the first time. A building complex made from mud bricks with mortar, interpreted as a potential early governor's residence, and a cache of colonial era police regalia.

While the window of opportunity for excavations was short, and studies of the excavated material are still ongoing, the Museum of West African Art Archaeology Project is already the most comprehensive archaeological study of the City of Benin, providing new information on all eras including the Kingdom of Benin in the immediate pre-conquest phase and the early colonial period. The project has the potential to greatly improve our understanding of urbanism, architecture, artisanal practice, ritual, trade, diet and the environment of pre-colonial Nigeria. The work has the potential to help establish the Museum of West African Art as a new, world class, research centre.

The Museum of West African Art was due to open on 11 November 2025, however, that opening has now been delayed, following a series of protests at the site on Sunday 9 November. These protests centre around the ownership of artefacts within the museum, many of which were looted by the British military in 1897. Many local people believe that these artefacts should be returned to the Kingdom of Benin, and therefore be placed in the custody of the current traditional ruler of the city, His Royal Majesty, Omo N’Oba N’Edo, Uku Akpolokpolo, Oba Ewuare II (CFR), the Oba of Benin.

The Museum of West African Art is a Federal Nigerian institution, and the protesters felt that, in containing objects they associate with the traditional office of the Oba, the museum was falsely presenting itself as a royal institution. The museum itself insists that it does not own any of the objects within it, but merely acts as a repository, exhibition centre, and place of study. This enables it to hold artefacts which European institutions have only returned on 'permanent loan', as well as exhibitions of art from other countries, or modern artists.

Eight confirmed deaths as Super Typhoon Fung-wong sweeps across

At least eight people have died after Super Typhoon Fung-wong (known as Super Typhoon Uwan inn the Philippines) swept across Luzon Island, the Philippines, on Saturday 8-Sunday 9 November 2025. This happened despite 1.4 million people being evacuated from areas deemed to be at risk from the storm. Three children are reported to have been killed in a landslide in Nueva Vizcaya Province, with another four being injured. Another landslide in the town of Lubuagan in Kalinga Province is known to have killed two people, with a further two missing, and another landslide killed an elderly person in Barlig, Mountain Provice. At least one person was killed in a flash flood in Pandan, Catanduanes Province. A woman is reported to have died in a house collapse on the island of Samar.

Tropical storms are caused by the warming effect of the Sun over tropical seas. As the air warms it expands, causing a drop in air pressure, and rises, causing air from outside the area to rush in to replace it. If this happens over a sufficiently wide area, then the inrushing winds will be affected by centrifugal forces caused by the Earth's rotation (the Coriolis effect). This means that winds will be deflected clockwise in the northern hemisphere and anti-clockwise in the southern hemisphere, eventually creating a large, rotating Tropical Storm. They have different names in different parts of the world, with those in the northwest Pacific being referred to as typhoons.

Despite the obvious danger of winds of this speed, which can physically blow people, and other large objects, away as well as damaging buildings and uprooting trees, the real danger from these storms comes from the flooding they bring. Each drop millibar drop in air-pressure leads to an approximate 1 cm rise in sea level, with big tropical storms capable of causing a storm surge of several meters. This is always accompanied by heavy rainfall, since warm air over the ocean leads to evaporation of sea water, which is then carried with the storm. These combined often lead to catastrophic flooding in areas hit by tropical storms.

Fung-wong was first observed as a convection current over the Central Pacific (about 560 km to the northeast of the island of Chuuk in Micronesia) on 3 November 2025. The current formed in an area with low vertical wind-shear and a sea surface temperature of 29–30°C (ideal conditions for tropical storm formation), and rapidly intensified, being officially upgraded to a tropical depression later that day. The system drifted to the east and gained in strength over the next 48 hours, being upgraded to a tropical storm and officially named Fung-wong by the Japanese Meteorological Agency on 5 November. 

By 6 November if was clear that the storm was heading towards the Philippines, causing the Philippine Atmospheric, Geophysical and Astronomical Services Administration to give it their own name, Uwan (the Philippines names storms according to its own system, and does not recognise names given by the Japan Meteorological Association, despite the fact that that body almost always detects Pacific storms first, and the use of names awarded by the Japanese by all other countries in the region). This is only the second time they have ever done this before a storm entered their waters, a sign of how concerned they were by the storm. On the same day the storm was upgraded to a Typhoon.

Colour indicated the severity of the storm. Tropical Storm Risk.

On 8 November, Fung-woon began to intensify rapidly being upgraded to a Super Typhoon 13.10 hours before making landfall in the Philippines. When it did it brought with it sustained winds of over 185 km per hour, and gusts of up to 230 km per hour, over a storm front about 1800 km wide. This was accompanied by very heavy rainfall, with many areas receiving more rain in 24 hours than they usually do in the entire month of November.

The high rainfall was particularly problematic, as Super Typhoon Fung-wong passed over the Philippines only four days after Typhoon Kalmaegi, itself a major storm which brought with it major flooding. This meant that rivers and lakes were already at or over their safe capacity, and soil in many areas was already waterlogged, when the storm hit, making the flooding caused by the new storm particularly intense.

As well as leading to larger and more frequent storms, warmer seas can enable them to change course rapidly, making it harder to predict where and when they will make landfall. This means that rising global temperatures, and the subsequent rise in sea temperatures, are both more and larger storms, but that tracking these storms is becoming much more problematic.

Bright fireball over Florida probably caused by space junk.

Witnesses In Florida, Georgia, South Carolina, North Carolina, Tennessee, Alabama, Louisiana, Mississippi, and Arkansas have reported observing a bright fireball meteor at about 6.15 am local time (about 11.15 am GMT) on Saturday 8 November 2025, with some witnesses in Florida and Georgia also reporting a sonic boom. The fireball is described as having moved from northwest to southeast, appearing over southern Georgia and disappearing off the east coast of Florida. A fireball is defined as a meteor (shooting star) brighter than the planet Venus.

Such are typically caused by pieces of rock burning up in the atmosphere, but can be the result of man-made space-junk burning up on re-entry, which appears to have been the case on 8 November. The object was visibly quite large, was relatively slow moving, and could be seen to break into a number of pieces as it passed through the atmosphere, none of which are conclusively signs of a man made object, but which combined together make this more likely. However, the nature of that object is unclear; the most common explanation for such re-entries is material falling back to Earth from a rocket launch, but while such a launch had been planned in Florida for that morning, it had not been due until an hour after the fireball event, and was eventually cancelled due to weather concerns.
