Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical -- OH -- and hydroperoxyl radical...
Plant scientists say circadian clock genes, which enable plants to measure daily and seasonal rhythms, should be targeted in agriculture and crop breeding for higher yields and more sustainable farming.

Research has shed new light on the impact of humans on Earth's biodiversity. The findings suggest that the rate of change in an ecosystem's plant-life increases significantly during the years following human settlement, with the most dramatic changes occurring in locations settled in the last 1500 years.
The European house mouse has invaded nearly every corner of the Americas since it was introduced by colonizers a few hundred years ago, and now lives practically everywhere humans store their food.
Researchers at Karolinska Institutet in Sweden have discovered a mechanism through which meningitis-causing bacteria can evade the immune system. In laboratory tests, they found that Streptococcus pneumoniae and Haemophilus influenzae respond to increasing temperatures by producing safeguards that keep them from getting killed. This may prime their defenses against our immune system and increase...
Researchers examined the guts of freshwater fish preserved in museum collections; they found that fish have been swallowing microplastics since the 1950s and that the concentration of microplastics in their guts has increased over time.
Oliver Burkeman’s long read pitches philosophical readers against the more scientifically minded onesI read the online version of Oliver Burkeman’s long read that raises the question of whether free will is an illusion, and shortly afterwards read the same article again in print (The clockwork universe, Journal, 27 April). I was surprised when I realised that the brief reference to quantum...
Dr Dominic Salisbury says poor-quality evidence lies behind some treatments such as CBT In reviewing the possible role of psychology in treating long Covid (Long Covid is very far from ‘all in the mind’ – but psychology can still help us treat it, 27 April), Dr Carmine Pariante misrepresents why many ME/chronic fatigue syndrome patients remain sceptical about psychological interventions such...
Venus is an enigma. It's the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.
Land productivity could be greatly increased by combining sheep grazing and solar energy production on the same land, according to new research by Oregon State University scientists.
The image of rows of chairs and desks facing a teacher at a blackboard has been a reality for decades. However, research reveals that this way of organizing the classroom furniture in schools is not the best way for favoring the learning process. Especially if the needs of 21st-century students are taken into account, who, according to the OECD, require a social environment that fosters autonomy,...
Small and medium-sized manufacturing enterprises (SMEs) face many obstacles and difficulties (economic, technical, cultural, etc.) when it comes to implementing Industry 4.0. "These are transition processes that are economically costly, and in which SMEs often come up against technical and cultural problems, as they are not cognizant of how to make this transition, or of the benefits their...
Microalgae of the dinoflagellate group are known for their ability to survive in other animal cells. These tiny single-cell organisms have engaged in mutually beneficial relationships with corals since primeval times. By passing on critical nutrients to their hosts, dinoflagellates allow corals to thrive even in barren areas. A research team from the Centre for Organismal Studies (COS) of...
Hydrogen as a clean, renewable alternative to fossil fuels is part of a sustainable-energy future, and very much already here. However, lingering concerns about flammability have limited widespread use of hydrogen as a power source for electric vehicles. Previous advances have minimized the risk, but new research from the University of Georgia now puts that risk in the rearview mirror.
The burden of student loans in the U.S. continues to grow unabatedly, currently accounting for a total of $1.7 trillion in household debt among nearly 45 million borrowers. "The introduction of income-based repayment over the past decade has made student loans rather complicated products," Paolo Guasoni of Dublin City University said. As borrowers navigate this complex process, they face long-term...
Individuals who self-identify as Republicans became more skeptical of a potential COVID-19 vaccine and other inoculations, such as the flu shot, over the course of the pandemic, reveals a new study by the University of California San Diego's Rady School of Management.
With threats of water scarcity complicating the need to feed a growing global population, it is more important than ever to get crop irrigation right. Overwatering can deplete local water supplies and lead to polluted runoff, while underwatering can lead to sub-optimal crop performance. Yet few farmers use science-based tools to help them decide when and how much to water their crops.
A study by University of Guam researchers has found that shade can mitigate the effects of heat stress on corals. The study, which was funded by the university's National Science Foundation EPSCoR grant, was published in February in the peer-reviewed Marine Biology Research journal.
Study of 11,584 staff found hesitancy was higher among BAME workers, as well as younger staffCoronavirus – latest updatesSee all our coronavirus coverageUp to a quarter of British healthcare workers have expressed hesitancy towards Covid-19 vaccines, the first comprehensive study of NHS and care staff suggests. Conspiracy beliefs, a paucity of black and ethnic minority participants in vaccine...
A new study documents an inexpensive, spark-free, optical-based hydrogen sensor that is more sensitive -- and faster -- than previous models.
Researchers have shown wearable devices that continuously monitor blood sugar provide new insights into the progression of Type 2 diabetes among at-risk Hispanic/Latino adults.
