The company has created qualification packs to define the competency standards that will provide a framework for academic institutions to design their course curriculum to better conform to industry hiring standards. These have been approved by National Skill Development Corporation (NSDC), National Skill Development Agency (NSDA), and National Skills Qualifications Committee (NSQC).

Hackers on Thursday disrupted a virtual session of South Africa's parliament, posting pornographic images in the second such incident since the coronavirus outbreak.

Old mining sites, such as quarries or pits, could provide refuges for endangered species, according to new research from the Czech Republic. Benefits are greater if the sites are allowed to recover naturally rather than being artificially restored with the use of topsoil, ground-levelling and seed planting.

A new study has compared conservation projects that focus on promoting only biodiversity with projects that focus on promoting both biodiversity and ecosystem services. The results dispel several myths surrounding ecosystem service projects and indicate they are as effective at addressing threats to biodiversity as their biodiversity counterparts.

A new study has identified several differences between two major European databases on alien species, which could be communicating mixed messages for biodiversity policymakers. Researchers recommend creating a single pan-European database to address these differences.

Ticks that are able to transmit Lyme disease are more abundant in deciduous oak forests than pine forests, according to a study conducted in Belgium, which provides an example of how landscape can influence human health. To help prevent tick attacks and the incidence of Lyme disease, the researchers suggest increased efforts are needed to raise public awareness of control measures, such as protective clothing and repellants.

Scientists have called for tighter biosecurity measures to reduce the growing threat to biodiversity, food security and ecosystems from fungal infections. Their study reveals that fungal disease outbreaks are on the rise around the world, and will cause further damage unless urgent steps are taken to restrict their unintentional spread through international trade and transport.

Reforms to reduce discards of over-quota fish catches are generally predicted to have positive effects on marine ecosystems and biodiversity. Although concerns have been raised over the impacts of the changes on scavenging seabirds who feed upon discarded fish, new research on gannets indicates that, while they often forage near fishing vessels, more than half their time is spent foraging 'naturally' in the open sea.

The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth's land surface, according to new research. The study focused on ‘drylands' – arid areas with low levels of rainfall – which support over 38%% of the world's population. Such nutrient imbalances could diminish the provision of ecosystem services, such as food production and carbon storage, the researchers say.

Acidification of water bodies can have substantial impacts on aquatic wildlife, and even after chemical conditions improve, biological recovery may lag behind. A study of Swedish lakes shows that, although their chemical quality has improved as a result of international reductions of acidifying emissions, biological recovery has been much slower in some lakes.

The future of oyster farming in Europe is threatened by disease. However, a recent study highlights the risk of importing oysters to improve or replace lost stock, as this could accidentally bring further disease and invasive species.

Discarding – returning unwanted catches to the sea – is seen as wasteful, but banning the practice would remove an important food source for many marine organisms. This study modelled the effects of gradually reducing and abruptly banning discards using data from a protected bay in Australia. The researchers recommend gradual reduction of discards in order to maintain ecosystem stability.

Street lighting reduces the number of moths at ground level and increases flight activity at the level of the lights, shows new research. Less pollen was transported by moths at lit sites in the UK study as a result of the disruptive effects on moth behaviour. The study highlights the need to consider both the direct and indirect ecological impacts of artificial light.

A new study has analysed marine litter on beaches across the UK, indicating that the fishing industry is responsible for large quantities of marine rubbish. The researchers recommend a combination of better enforcement of regulations covering waste disposal, and incentives for fishing vessels to reduce marine litter.

Wildfires are projected to become an increasingly common occurrence and are a major driver of habitat disturbance, yet little research to date has examined how the relationship between fire and landscape attributes affects large carnivores, such as the grey wolf (Canis lupus). The results of this study suggest that wolves are remarkably resilient to fire, persisting and breeding in a human-dominated landscape even under intensive fire regimes. However, burnt landscapes may induce higher exposure to human disturbance and persecution due to limited refuge conditions.

As many universities are moving quickly to distance learning, it is vital for educators to think carefully about how to adapt their approach to still deliver key learning outcomes for students in an online setting. Today’s guest blogger, Ramnarayan Krishnamurthy, is at the forefront supporting universities as they transition to distance learning. In his role as a Customer Success Engineer, he partners with educators to support them in achieving their goals for teaching and learning.... read more >>

The Deepwater Horizon Oil Spill saw the first ever use of chemical dispersants to reduce the impacts of an oil spill at a deepwater level. A new study has investigated the fate of these dispersants in deepwater and concluded that they do not biodegrade well.

There has been an established increase in reproductive disorders and other hormonal diseases, according to a recent European Environment Agency (EEA) report. The report documents a growing body of research that indicates this increase is influenced by growing levels of chemical pollutants in the environment known as endocrine disrupting chemicals (EDCs).

Endocrine disrupting chemicals (EDCs) can interfere with the hormonal systems of both humans and wildlife. New research quantifying EDCs in marine environments in Greece found concentrations which present significant risks to sediment-dwelling organisms.

Farmers could help to maintain populations of bees and other pollinators by sowing inexpensive seed mixes on their land, a new study suggests. Researchers surveyed pollinators visiting study plots in Berkshire, UK, and explored how sowing different seed mixes and using different management techniques affected the flowers produced and the pollinators visiting them.

Oil spills at sea can be catastrophic events, with oil and discharged toxins, including polycyclic aromatic hydrocarbons, threatening marine wildlife and coastlines, damaging healthy ecosystems and harming livelihoods. A recent study found that using dispersants moderately decreased the number of cod eggs and larvae affected by spills off the Norwegian coast.

Cyanobacteria — often referred to as blue-green algae — are found in water bodies around the world and can produce toxins with potential health risks. This US-wide study found a significant positive association between cyanobacterial bloom coverage and death by non-alcoholic liver disease. The researchers say their study suggests some evidence of a potential health risk and should be used to generate further investigation into the health impact of cyanobacteria.

Halogenated nitrogenous disinfection by-products (N-DBPs) in water increase bacterial resistance to antibiotics, new research shows. The study found that a strain of bacteria which can cause disease in humans, Pseudomonas aeruginosa, increased its resistance to a range of different antibiotics by an average of 5.5 times after the bacteria were exposed to chemicals which form as by-products of common water treatment procedures. The results highlight the risks to public health which these currently unregulated by-products may cause.

A growing body of evidence suggests that endocrine-disrupting compounds (EDCs) are contributing to declines in fertility. This case-control study found that EDCs were associated with changes to sex hormones and risk of subfertility in men. The researchers say environmental levels of these chemicals should be reduced to protect male fertility.

Researchers have recommended that fish from some sections of the River Po and the River Lambro, one of the Italian River Po tributaries, should not be eaten due to high levels of some endocrine-disrupting chemicals in the river sediments and fish. This recommendation is based on an extensive update regarding pollution levels of such substances in the rivers.

Bisphenol A (BPA) is a chemical that is widespread in the environment. Researchers reviewed and critically discussed the sources and routes of human exposure to chlorinated derivatives (ClxBPA) and alternatives to BPA (BPF, BPS), as well as their metabolism, toxicity and concentrations in human tissues. The researchers suggest BPA alternatives and derivatives may have similar effects, and provide directions for future research.

Widespread use of antibiotics has led to pollution of waterways, potentially creating resistance among freshwater bacterial communities. A new study looked for antibiotic resistance genes in a river basin in Spain, revealing that wastewater discharges can promote the spread of antibiotic resistance in streams and small rivers.

Pollutants have been shown to alter the structure of bacterial communities in the coastal waters around the Alang-Sosiya shipbreaking yard in north-west India. The research analysed seawater from two sites near Alang-Sosiya and from pristine sea water taken 10 km from the coast. The results provide a clearer idea of changes to the microbial ecology near a large ship recycling yard.

The pathways for removal of dissolved phosphorus within biofiltration systems have been examined in a new study. Over 95% of phosphorus was removed over the study period, with the majority of phosphorus stored within plants. The researchers say the findings demonstrate the value of using suitable plant species within biofiltration systems to treat polluted water.

Researchers in Spain have analysed waste water to calculate levels of exposure to phthalates in individuals. The calculations showed that levels of four types of phthalate exceeded safe daily limits in some of the sites studied, with levels of exposure in children being of particular concern. Using the results of waste-water analysis in this way can identify areas where action may need to be taken to lower exposure.

Personal Care Products (PCPs) are of increasing global concern, as thousands of tonnes enter the environment every year. Similar to persistent organic pollutants (POPs), some substances used in PCPs are toxic, persist in the environment and accumulate in the bodies of organisms that take them in. This study focused on the presence of ultraviolet filters (UV-Fs) (used in PCPs such as sunscreens and cosmetics) in the unhatched eggs of wild birds.

The presence of disinfection by-products (DBPs) in drinking water is an emerging health concern. DBPs come in many classes and are chemically diverse, making them challenging to monitor. Swedish researchers have evaluated a new method for the simultaneous determination of a broader range of DBPs than typically possible using other available techniques. The method uses gas chromatography (a laboratory technique that separates and analyses vaporisable compounds in a mixture), together with a halogen-specific detector (XSD). Having been tested in real water samples from two municipal waterworks in Sweden, the method has been optimised for the simultaneous determination of a wide range of neutral DBPs.

When working on the "Color Image Processing" chapter of DIPUM3E, I found myself often wanting to display square blocks (or swatches) of color, like this:... read more >>

A recent study has compared the impact of future power generated from large, central stations with power generated from smaller distributed generators (DG) in California on air quality. It concluded that although DG produces more emissions, its impact on air quality is likely to be smaller than central power stations due to complex interactions between air chemistry and transport.

Evidence from modelling studies suggests that climate change is likely to increase concentrations of ozone, one of the most important urban air pollutants responsible for respiratory problems. Under this assumption, rapid reductions of emissions from fossil fuel burning are needed to protect the health of both current and future generations.

For the first time, scientists have identified an ‘ozone hole’ over the Arctic, in addition to the well-known ozone hole over the Antarctic. Unusually persistent low temperatures over the arctic in early 2011 caused an unprecedented amount of chemical destruction of stratospheric ozone there. The authors warn that this is likely to happen again, although it is presently difficult to predict when this might be.

A study in the Czech Republic has found a link between exposure to certain air pollutants and an increase in DNA damage for people exposed to high levels of the pollution. They found that breathing small quantities of a polycyclic aromatic hydrocarbon (PAH), called benzo[a]pyrene (B[a]P), caused an increase in the number of certain ‘biomarkers’ in DNA associated with a higher risk of diseases, including cancer.

There is a growing body of scientific research into the health benefits of urban forests, such as improving air quality and providing recreational space. However, new research challenges the assumption that their overall impact on quality of life is always positive and land planners need to take into account ecosystem disservices as well as services, say the researchers.

A strong link between long-term exposure to vehicle pollution and deaths from heart disease and lung cancer has been found in a study of over a million individuals. The researchers say their results are relevant to European policymaking relating to air quality.

Airborne particulate matter pollution leads to increases in death rates among people with underlying health conditions such as heart disease, according to a new study. The study suggests the effects are mainly related to the air pollution known as PM_{2.5 - particles smaller than 2.5 micrometres (μm). The study is the first to assess the health effects of this type of pollution across several European countries at once.}

Indoor air quality can be significantly improved using a simple device which traps harmful chemicals emitted from glues, paints and building materials, a new study has shown. Designed in Sweden, the researchers demonstrate that the 'surface emissions trap', especially effective for damp buildings, also prevents emissions from mould and can remove unpleasant odours.

Air pollutants and greenhouse gases (GHGs) from a coal-fired power station have been correctly identified 12 km away, researchers report in a new US study. Their monitoring method paves the way for a space-based satellite system which can check emissions reported by individual power stations against actual emissions.

Fires in forests contaminated by the Chernobyl nuclear accident could lead to areas of Europe and Russia being exposed to further radioactive fallout, new research has found. The study examined the spread of the fallout and the health effects on people and animals under three different scenarios: 10, 50 and 100% of the forests being burnt.

The chances of a child developing Autism Spectrum Disorder (ASD) are higher if the mother is exposed to high levels of fine particulate air pollution during pregnancy, a recent study suggests. This increased risk was associated specifically with exposure in the last three months of pregnancy, the researchers found.

New research suggests that fungi could be used to control insect-borne diseases common in livestock. The study shows for the first time that a fungus can effectively kill adult midges in the family of insects that carry bluetongue virus (BTV). Bluetongue outbreaks have caused significant losses on European farms in recent years, and the study indicates that using the fungus as a means of biological control could help reduce reliance on chemical insecticides, in the absence of effective vaccines.

Mining uranium ore leaves sites contaminated with toxic, radioactive material. According to a new study, contaminated sites can be treated with sludge from the treatment of distillery wastewater in bioreactors. The study demonstrates an efficient method for decontamination of groundwater based on bacteria in sludge that naturally convert uranium into an insoluble form that can be more easily removed.

Researchers have identified plant fungi in the Ecuadorian rainforest that can digest plastic. The discovery hints that there may be a wide range of effective waste-consuming microbes in existence, according to the study, which found that several different fungi, including one called Pestalotiopsis microspora, can break down the widely used plastic, polyurethane.

A species faced with extinction is more than a potential tragedy for the species concerned. Human wellbeing and economy depend on the world’s biodiversity and ecosystem services, but human actions are damaging the environment and threatening the existence of countless organisms that have, or could provide, humankind with valuable medicines, according to a recent publication.

Preserving biodiversity seems to reduce the emergence and spread of human diseases in many cases, according to an investigation into the links between biodiversity and human health. It concludes that there is mounting evidence indicating that preserving ecosystems in their natural state generally decreases the occurrence of infectious diseases.

It is increasingly evident that human health is closely linked to the environment, and to biodiversity. A study commissioned by the European Commission summarises the many and varied ways in which disturbances to biodiversity affect the spread of human diseases.
