Fertilisers recycled from human urine, feces are ‘environmentally safe’: Study
The paper published on 16 January in the journal Frontiers in Environmental Science confirms the ecological and economic feasibility of recycling our body waste as fertilizer, provided there is no risk that harmful microbes or traces of drugs end up in the crops that are consumed.
Over-use of antibiotics kills thousands annually in Egypt and Sudan
The story dates back to November 2021, when her father developed an infection and symptoms of coughing, sweating, shaking chills, fever and chest pain. He was diagnosed with pneumonia and given standard antibiotics, but they didn’t work; he needed stronger, more expensive drugs. After trying different things with no improvements, the doctors told Nada there was nothing they could do for him, she recalls in Cairo, crying.
Increasing plant cooperation, crop yields through breeding: Study
Simple experiments may rapidly identify genes that allow success in dense plantings
New single-dose treatment for sleeping sickness could help stop its transmission by 2030
Sleeping sickness, or human African trypanosomiasis (HAT), is a neglected tropical disease, which can be fatal if left untreated. The Gambiense human African trypanosomiasis (g-HAT) form of the disease is found across countries in west and central Africa with most cases in the Democratic Republic of Congo.
New research shows commitments for forests are nowhere near what’s needed to reach Paris Agreement ambition
The world is not on track to achieve forest goals of ending and reversing deforestation by 2030, critical for a credible pathway to the 1.5°C Paris Agreement goal, according to a new report by the UN-REDD Programme, UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) and the Green Gigaton Challenge (GGC). It finds that for the …
Ancient bacteria might lurk beneath Mars’ surface
These findings strengthen the possibility that if life ever evolved on Mars, its biological remains might be revealed in future missions, including ExoMars (Rosalind Franklin rover) and the Mars Life Explorer, which will carry drills to extract materials from 2 meters below the surface.

Researchers show how the debris leaks dangerous chemical contaminants, affecting marine microorganisms
Floods threaten food security in Africa
Floods can affect food security both immediately and in months following heavy rain
Heated tobacco products: How are they different from conventional cigarettes?
Scientific research studies confirm the harmful effects of smoking conventional cigarettes on human health and stress that the process of burning tobacco in a cigarette is the primary cause of smoking-related diseases. Hence, in the past 15 years, researchers across the world examined innovative approaches and alternative products that have the ability to reduce the …
Cannabis use increases pain after surgery, study shows
“Cannabis is the most commonly used illicit drug in the United States and increasingly used as an alternative treatment for chronic pain, but there is limited data that shows how it affects patient outcomes after surgery,” said Elyad Ekrami, M.D., lead author of the study and clinical research fellow of the Outcomes Research Department at Cleveland Clinic’s Anesthesiology Institute.

NASA crashed a spacecraft into an asteroid – photos show the last moments of the successful DART mission
The Double Asteroid Redirection Test – or DART – is meant to test one potential approach that could prevent an asteroid from colliding with Earth.
NASA conducts first planetary defence test mission
A NASA spacecraft intentionally slammed into an asteroid on Monday in a test to protect Earth in case of an asteroid impact threat. The agency’s Double Asteroid Redirection Test (DART) probe carried out the first-of-its-kind manoeuvre on a small space rock known as Dimorphos, about 11 million km from Earth. The impact took place at …
Earth harbours 20,000,000,000,000,000 ants – and they weigh more than wild birds and mammals combined
There are more than 15,700 named species and subspecies of ants, and many others not yet named by science
Nightmares are a good predictor of future dementia – new study
Interestingly, the connection between nightmares and future dementia was much stronger for men than for women.
Tiny algae could help fix concrete’s dirty little climate secret – 4 innovative ways to clean up this notoriously hard to decarbonize industry
Humans produce more concrete than any other material on the planet. It is the literal foundation of modern civilization – and for good reason. Concrete is strong, durable, affordable and available to almost every community on the planet. However, the global concrete industry has a dirty little secret – it alone is responsible for more …
Exposure to past temperature variability may help forests cope with climate change
Study identifies trends linking temperature variability and forest productivity
Molecular brain changes linked to main susceptibility gene for Alzheimer’s disease
A new study from the Keck School of Medicine of USC, published on Tuesday in the Journal of Experimental Medicine, adds a crucial piece to that puzzle. It documents in real time that APOE4, the main susceptibility gene for Alzheimer’s disease, leads to molecular changes in the brain’s blood vessels, which are then followed by changes in the synapses that connect brain cells.
Poor heart health predicts premature brain ageing
A higher brain age was associated with slightly worse scores on cognitive tests, and also predicted increased brain shrinkage (atrophy) over the following two years, suggesting it could be an important clinical marker for people at risk of cognitive decline or other brain-related ill health.
Procrastinating is linked to health and career problems – but there are things you can do to stop
Unfortunately, telling yourself off won’t stop you procrastinating again. In fact, it’s one of the worst things you can do.
Fish ‘chock-full’ of antifreeze protein found in iceberg habitats off Greenland
The study, led by scientists at the American Museum of Natural History and the City University of New York (CUNY), and published on Tuesday in Evolutionary Bioinformatics, also warns that warming oceanic temperatures in the Arctic could pose a threat to these highly specialized fishes.
Researchers warn fish are suffering from oxygen decline
Larger fishes are more likely to experience oxygen deficiency in warm water than smaller species
Nuclear war would cause global famine, kill billions
Even a nuclear conflict between rising nuclear powers would decimate crop production and result in widespread starvation
Using smartphones could help improve memory recollection
The research — published in the Journal of Experimental Psychology — showed that digital devices help people store and remember very important information.
