South African diamond mining company files for bankruptcy after five miners killed in flood.

South African mining company Ekapa Minerals has filed for liquidation following the death of five miners at its Ekapa Joint Shaft Mine at Kimberly in Northern Cape Province, South Africa, on 17 February 2026. The miners have been missing presumed dead since a slurry of water and mud rapidly filled the section of the mine where they were working. The area where the incident occurred was located 890 m below ground, and had only recently been opened up, and life support systems had been installed, but the sudden nature of the flood has led the mine operators to conclude that the incident was not survivable, and, following several days of attempts to reach and clear the site, that there is little hope of recovering the bodies of the lost miners.

Floods and inrushes typically occur when miners accidentally break through into pockets of water and gas trapped within rocks. Since such buried waters are often under high pressure due to the weight of rocks above them, they tend to escape into the mine rapidly, and on occasion explosively, leading to a highly dangerous situation in which miners are often rapidly overwhelmed. Such inrushes can also occur when miners encounter flooded disused mineworkings, a danger in areas where mining has occurred for a long time but good records have not been kept. The Ekapa mine had a history of flood inrush events, and the company had been warned by a parliamentary committee in 2025 that steps needed to be taken to avoid future events of this kind.

The closure of the mine is predicted to result in the loss of about 1200 jobs, a crisis for the city of Kimberly, which has a population of just under 97 000 people, and is already suffering from high unemployment rates due to the decline of the diamond industry. Furthermore, workers from the site report that they have not received their salaries for the month of February 2026, placing many of the in a very difficult situation financially. 

Ekapa Minerals purchased the Joint Shaft Mine from mining giant De Beers in 2016, and at the time of closure it was the last surviving diamond mine in Kimberly. In theory, the site could be sold on to another mining company following the liquidation process, but it is unclear if a buyer will be found given the mine's problems and a fluctuating diamond market.

Kimberly was founded in the 1870s following the discovery of diamonds in the area, and rapidly became a centre of wealth in the Cape Colony, opening South Africa's first stock exchange in 1881, and becoming the second city in the world to install electric street lighting the following year. However, in recent years the city's mines have closed one-by-one as the industry has become less viable. The long history of mining in the area means that there are no diamonds left close to the surface, and while they can still be found at greater depths, these are generally fairly small, making it hard for these mines to compete with either shallow, open pit mines elsewhere, or artificial lab-grown diamonds.

Denmark officially recognised as having ended mother-to-child transmission of HIV and Syphilis.

Denmark has been officially recognised as having eliminated mother-to-child transmission of HIV and Syphilis according to a press release issued by the World Health Organization on 27 February 2026. In doing so it becomes the first member of the European Union and the third European country to achieve this status (behind Moldova and Belarus, both of which were confirmed as having ended mother-to-child transmission of both diseases in 2016).

The World Health Organization is aiming for all countries to achieve the triple elimination of mother-to-child transmission of three critical diseases, HIV, Syphilis, and Hepatitis B, although to date only a single country has passed this milestone, the Maldives in October 2025. Denmark's progress makes it one of 23 countries to have ended mother-to-child transmission of at least one of these diseases, alongside Anguilla, Antigua and Barbuda, Armenia, Belarus, Belize, Bermuda, Brazil, Botswana, Cayman Islands, Cuba, Dominica, Jamaica, Malaysia, Maldives, Montserrat, Namibia, Oman, Republic of Moldova, Saint Vincent and the Grenadines, Sri Lanka, St. Kitts and Nevis, and Thailand.

The confirmation of Denmark's status comes following assessments by the World Health Organization's Regional Validation Committee for Europe, and Global Validation Advisory Committee in 2025. In order to be confirmed, it was necessary to demonstrate that 95% of all pregnant women in Denmark were tested for the diseases, and that new infant infections were below 50 in 100 0000 births. Denmark currently has 5950 people living with HIV, with less than 0.1% of pregnant women affected. It is possible to completely suppress the disease with antiretroviral treatments, preventing development of symptoms and all forms of transmission, including mother-to-child. In 2024, Denmark reported 626 cases of Syphilis, 524 in men and 102 in women; infections with this disease can be eliminated with antibiotics. Denmark is still working towards ending mother-to-child transmission of Hepatitis B.

Human Immunodeficiency Virus, or HIV, is a form of Lentivirus which causes infections in Humans, spread through sexual intercourse or exchange of blood. Notably, the Virus infects the cells of the Human immune system, where it is hard for that immune system to attack, and eventually leads to a breakdown of the immune system known as AIDS (Acquired Immune Deficiency Syndrome), during which the body becomes vulnerable to a wide range of infections, including many by micro-organisms which are not usually pathogenic. 

Untreated, HIV invariably leads to AIDS, and AIDS is invariably fatal, but, as with Syphilis, HIV infections can go through long phases of dormancy, leaving infected people unaware that they have the disease. Neither an effective vaccine nor a cure for HIV has yet been developed, however, it is possible to suppress the infection with a combination of anti-viral drugs, allowing patients to lead relatively normal lives, as long as their supply of antivirals is not interrupted. Children born to mothers with HIV are not automatically infected, as the Virus is usually unable to cross the placenta, but there is a high chance of infection during birth if the mother is not receiving treatment.

Syphilis is a sexually transmitted disease caused by the Spirochaete Bacterium Treponema pallidum. The symptoms of Syphilis can be variable, and it can go through long periods of dormancy, making the disease difficult to diagnose without modern testing methods. Syphilis infection in pregnant women leads to a raised risk of miscarriage, and infants born with the disease are prone to physical deformities, damage to the liver and spleen, and neurological problems. Syphilis can be treated with a range of antibiotics, including penicillin, although the development of a vaccine has proved difficult.

Mud volcano reported to have killed several Cattle near the town of San Juan de Urabá in Colombia.

A number of Cattle are reported to have died following a mud volcano eruption near the town of San Juan de Urabá in Antioquia Department on the Caribbean coast of Colombia on 25 February 2026. The volcano erupted at about 6.20 pm local time, producing a large column of fire as ejected gas ignited, setting fire to vegetation and damaging the road between San Juan de Urabá and San Juancito, which drivers are advised to avoid until repairs are carried out and an assessment of potential future hazards is carried out.

Unlike regular volcanoes, mud volcanoes are not caused by magma erupting from within the Earth's interior, but rather gasses escaping from buried sediments closer to the surface. Typically this is methane generated by the decomposition of buried vegetation in areas where sediments are accumulating rapidly, leading to the decaying material becoming pressurised. Under these circumstances, the compressed gas will force its way through any cracks into softer layers above (the mud), then erupt rapidly, often bringing lighter oil fractions, also produced by the decomposition of plant material, with it. This creates an explosive mixture, which often ignites in the way seen in Colombia this week, although on other occasions more liquid mud than flammable gas is ejected, creating a messier, but less dramatic eruption.

Total Lunar Eclipse to be visible from East Asia, East Australia, Oceania, the Pacific Ocean, and western North America.

A total Lunar Eclipse will occur on Wednesday 3 March 2026, starting at 8.45 am GMT. It will be visible across the eastern parts of Asia, Australia, and Indonesia, as well as the rest of Oceania and the Pacific Ocean, the western part of North America, and parts of Antarctica. In Southeast, South, and Central Asia, western Australia and Indonesia, and much of North, Central, and South America, Greenland, and the Caribbean, part of the eclipse will be visible, although in these areas the Moon will either rise part way through the eclipse, or set before it is complete in these areas.

The Moon produces no light of its own, but 'shines' with reflected light from the Sun. Thus at Full Moon the Moon is on the opposite side of the Earth to the Sun, and its illuminated side is turned towards us, but at New Moon the Moon is between the Earth and the Sun, so that its illuminated side is turned away from us.

Lunar eclipses occur when the Moon passes through the Earth's shadow. This can only happen at Full Moon (unlike Solar Eclipses, which happen only when the Moon passes between the Earth and the Sum, and therefore only occur at New Moon), but does not happen every Lunar Month as the Sun, Moon and Earth are not in a perfect, unwavering line, but rather both the Earth and the Moon wobble slightly as they orbit their parent bodies, rising above and sinking bellow the plane of the ecliptic (the plane upon which they would all be in line every month).

Astragalus centralis: The Tamditau Milkvetch evaluated as Critically Endangered.

Milkvetches, Astragalus spp., are leguminous herbs of or shrubs, predominantly found in arid or semi-arid climates around the Northern Hemisphere. They are a large group of Plants, with 3082 species recognised in 2025, this is largely because many species are highly endemic (i.e. have very limited ranges). Such limited ranges can make species extremely vulnerable to extinction, though to date only 149 species of Astragalus have been formerly assessed to determine their status under the terms of the International Union for Conservation of Nature's Red List of Threatened Species, with 36% of these being determined to be threatened, and one, the Tallante's Milkvetch, Astragalus nitidiflorus, has been found to be extinct in the wild.

Thirty two species of Astragalus have been recorded in Uzbekistan, more than any other genus in the country. Most of these are found within the low mountain ranges of the Kyzylkum Desert, a notable centre of Plant endemism covering parts of Uzbekistan, Kazakhstan, and Turkmenistan. Within this desert a series of low mountain ranges (typically lower than 1000 m) form a western extension of the Central Asian Mountain Belt, creating a range of distinctive micro-habitats. promoting Plant endemism. Of the forty two species of Astragalus known from this region, six are thought to be entirely endemic. 

In a paper published in the journal Orynx on 18 February 2026, Bekhruz Khabibullaev, Khabibullo Shomurodov, and Natalya Beshko of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan, and Giuseppe Fenu of the Department of Life and Environmental Sciences at the University of Cagliari, formally assess the conservation status of Astragalus centralis, referred to here as the Tamditau Milkvetch, an endemic species from the Kyzylkum Desert of Uzbekistan. 

The Tamditau Milkvetch is a perennial herbaceous Plant reaching about 15 cm in height, with stems covered in white hairs, paired leaves, and dense inflorescences of yellow flowers. It was formerly thought to be present in the Tamditau, Kuldzhuktau, and Auminzatau mountain ranges within the Kyzylkum Desert. However, a previous study, published in 2016, established that the populations in the Kuldzhuktau and Auminzatau mountains were in fact a separate species, which was described as Astragalus kuldzhuktauense. 

As a result of this, the known occurence of Astragalus centralis shrank to a single population in the Tamditau Mountains, prompting monitoring and censuses of the species in 2016-17, 2018-19, and 2023-24, each time assessing the number of Plants present at the peak of the flowering season.

The Tamditau Milkvetch grows on northern slopes in the Tamditau Mountains, in crevices between large boulders in gravelly and rocky limestone soils. All known members of the species are found within an area of 60 000 m². During the 2016-17 season, about 1000 Plants were recorded, but in 2018-19 this had fallen to about 600 individuals, within an increased proportion of older Plants (80% against 50% in 2016-17. In 2023-24 only 491 Plants were recorded, with 90% of these being mature.

The species appears to be facing a number of immediate threats. Limestone is extracted in the region, and new excavation trenches are both present and increasing in number within the range of the Tamditau Milkvetch. The population is also located close to a settlement which primarily derives its income from livestock herding, with the area where the species grows being used as a year-round pasture. Climate change appears to be making the area more arid, and Insects have been observed to consume more of the species seeds in dryer years. This drying climate is also associated with more frequent and intense spring flash floods, which can destroy younger Plants with less well established root systems. The species is also vulnerable to short-term cold anticyclones, which occur in the area every 5-6 years.

Based upon this, Khabibullaev et al. suggest that the Tamditau Milkvetch is becoming unable to sustain its only population, due to a low and decreasing survival rate for young Plants. For this reason they recommend that the species be classified as Critically Endangered under the terms of the International Union for Conservation of Nature's Red List of Threatened Species.

Based upon this, Khabibullaev et al. recommend a series of steps to be taken in order to protect the future of the Tamditau Milkvetch. 

Firstly, the species habitat should be designated a protected area. This would not just protect this species, but also other species found in the area which have been identified as at risk, including the Kyzylkum Giant Fennel, Ferula kyzylkumica, the Aktavi Stickseed, Lappula aktaviensis, The Kyzylkum Peppergrass, Lepidium subcordatum, the Hairy Catchfly, Silene tomentella, and the Aktau Needlegrass, Stipa aktauensis. They further recommend that the Tamditau Mountains should be considered to be a significant national ecosystem, and assessed for potential inclusion on the nternational Union for Conservation of Nature's Red List of Ecosystems.

Secondly, they recommend that an inventory of pasture resources in the region is carried out, in order to determine the sustainable grazing capacity of the area, and develop a better plan for livestock management.

Thirdly, they suggest a translocation strategy for the species, moving individual Plants to other areas identified as suitable for its survival.

Fourthly, they suggest that a cultivated population be established at the Kyzylkum Desert Experimental Station, and seeds of the species be gathered and placed in an appropriate seed bank.

Finally, they suggest that the species be included on the International Union for Conservation of Nature's Red List of Threatened Species, and an awareness campaign for the species be used to promote its conservation.
