Thousands of new findings contribute to a global virus map

An extensive study has mapped RNA viruses in a large number of cities around the world. The researchers identified nearly 55,000 different types of virus, the vast majority of which had never been observed before. The virus atlas could be useful in both biological risk assessment and crime scene investigations. Surprisingly little is known about how virus populations are distributed across the pla

Car exhaust fumes linked to DNA damage and weakened immunity in city birds

Air pollution does not only harm human health. New research shows that birds also experience measurable biological changes after breathing in soot particles from traffic emissions. While the effects of polluted air are well documented in humans, far less is known about how animals with different physiologies respond. A new doctoral thesis from Lund University provides fresh evidence of how vehicle

New DNA technology could support police investigations

Where were the suspects located before a crime was committed? Where was a bomb assembled or a batch of drugs produced? A new technique that analyses environmental DNA could help provide answers. Geneticist Eran Elhaik at Lund University has developed an AI-based tool designed to support forensic investigations. The technology uses environmental DNA (eDNA) to help determine geographical origin from

Snow fly beats the freeze with built-in ‘heat pulses’

A tiny insect that lives on snow has revealed an unexpected survival trick: it can generate its own heat to withstand sub-zero temperatures. The finding sheds new light on how life endures in extreme environments. The snow fly – a winter-active crane fly – moves across snow at temperatures between 0 and −7°C. Conditions that would be lethal to most insects instead leave this species active, thanks

Dragonflies Challenge Classical Theory

Researchers have now tested a prevailing theory about the relationship between body size and metabolism in animals. Their study overturns decades of research that has maintained that metabolic rate always increases more slowly than body size. For decades, it has been regarded in biology as a natural law that there is a fixed relationship between body size and metabolic rate across all animal group

Genes from the Ice Age Guide Migratory Birds’ Detours to Africa

A pied flycatcher from Siberia flies over 4,500 kilometres farther than necessary to reach its wintering grounds in Africa. The reason is that the birds’ migration route is still guided by genetic instructions from the last Ice Age. How migratory birds find their way to their wintering grounds and back to their breeding sites has long been one of biology’s great mysteries. In a new study published

Researchers solve mystery of how plants sense touch

A feather-light touch can trigger a chain reaction in a plant in less than a minute. Researchers at Lund University have identified the molecular signaling pathway that links mechanical stimulation to changes in plant genes and growth. Plants cannot run away when the wind picks up, rain lashes down, or a hungry herbivore begins chewing on their leaves. Instead, they must sense their surroundings a

Nightjar wings reveal a trade-off between hunting slowly and travelling far

The nightjar migrates thousands of kilometres, yet the same wings must also help it catch insects at low speeds. A new study from Lund University shows how these competing demands have shaped the bird’s flight performance. The European nightjar (Caprimulgus europaeus) is a nocturnal migratory bird that travels between Europe and southern Africa each year. However, its wings are not only used for l

Symposium “Climate development and ocean dynamics during the last glacial - interglacial cycle”. June 12 09.00-16.50

This article is over 5 years old, and the information may therefore be outdated. Department of Geology organizes a full day symposium on the theme “Climate development and ocean dynamics during the last glacial - interglacial cycle” as a tribute to Professor Svante Björck and his research in Quaternary Science for more than 40 years because of his retirement from the Chair in Quaternary Geology on

Traces of enormous solar storms in the ice of Greenland and Antarctica

This article is over 5 years old, and the information may therefore be outdated. Solar storms and the particles they release result in spectacular phenomena such as auroras, but they can also pose a serious risk to our society. In extreme cases they have caused major power outages, and they could also lead to breakdowns of satellites and communication systems.According to a study published today i

Is OA linked to cancer?

In a new Swedish study by Lund University on comorbidities in osteoarthritis, researchers studied if people with osteoarthritis are at an increased risk for cancer compared to people without osteoarthritis. The study focused on the four most common cancer types, lung, colon, breast, and prostate cancer. Researchers found no differences in the risk of being diagnosed with colon cancer if you had os
