NewsCells ‘repress’ genomic remnants of ancient viruses
Researchers have identified key cellular control sites that regulate gene expression and prevent the activation of ‘cryptic’ genomic regions, including ancient viral sequences.

NewsCatalogue of fungi in China reveals new taxa of macrofungi from southern Xizang
During a field trip in July 2023 in the Himalayas, 882 specimens in six counties from the border area of Xizang, China were collected, among which 15 new macrofungal species were revealed and are described in the study.

NewsResearchers uncover new infection-fighting molecules through ‘molecular de-extinction’
A new study has uncovered sequences for ancient antimicrobial agents in the genomic data of extinct species, offering new hope for the development of antibacterial, antifungal, and antiviral treatments.

NewsIt’s the unchanging parts of the Covid virus we also need to pay attention to, study suggests
A new study demonstrates the value of surveillance for public health initiatives, while identifying stable parts of the virus as potential candidates for small molecule drugs and other drug development.

NewsResearchers create new framework to understand how microbial communities emerge
Virtually all multicellular organisms on Earth live in symbiotic associations with very large and complex microbial communities known as microbiomes. New research has just been published aimed at offering a complete understanding how those relationships form.

News‘Ice bucket challenge’ reveals that bacteria can anticipate the seasons
Bacteria use their internal 24-hour clocks to anticipate the arrival of new seasons, according to research carried out with the assistance of an ‘ice bucket challenge’.
-
NewsBacterial cells transmit memories to offspring
Bacterial cells can “remember” brief, temporary changes to their bodies and immediate surroundings, a new study has found.

NewsLocked in a glacier, viruses adapted to survive extreme weather
Ancient viruses preserved in glacial ice hold valuable information about changes in Earth’s climate, a new study suggests.

NewsWhat microscopic fossilized shells tell us about ancient climate change
New research pairs sea surface temperatures with levels of atmospheric CO2 during the end of the Paleocene, showing the two were closely linked.

NewsStudy reveals isolation, endogamy and pathogens in early medieval Spanish community
An archaeogenetic study sheds new light on the isolated medieval community Las Gobas in northern Spain. The researchers have identified the variola virus which can offer a new explanation on how smallpox entered Iberia.

NewsCreature the size of a dust grain found hiding in California’s Mono Lake
Researchers have now found an unusual creature lurking in the shallows of Mono Lake — a choanoflagellate that could tell scientists about the origin of animals more than 650 million years ago.

NewsNext time you beat a virus, thank your microbial ancestors
When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors. Two key elements of our innate immune system came from a group of microbes called Asgard archaea.

NewsFungal discovery changes the way we understand Charles Darwin’s most beloved plant – the sundew
A new study has uncovered a symbiotic relationship that has evolved between Darwin’s favourite carnivorous plant and a specific type of fungus which lives inside it and helps it digest its prey.

NewsRed Queen arms race over millions of years preserves genetic diversity in water flea
Host/parasite arms races can occur without interruption over many millions of years, a much longer period than previously thought, according to scientists who compared the genetic material of millimeter-sized water fleas infected by a parasitic bacterium.

NewsStudy analyzes potato-pathogen ‘arms race’ after Irish famine
In an examination of the genetic material found in historic potato leaves, researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine.

NewsAncient Antarctic microorganisms are aggressive predators
Antarctic dwelling single-celled microorganisms called archaea can behave like parasites, new research shows.
-
NewsWarming stops tiny organisms working together
The single-celled organism Paramecium bursaria can absorb and host algae (Chlorella spp), providing benefits for both, but when scientists made the water 5°C warmer, the partnership stopped working – and the algae may even become parasitic.

NewsShared geographic origin of TB strain and human host could boost risk of infection
For some forms of tuberculosis, the chances that an exposed person will get infected depend on whether the individual and the bacteria share a hometown, according to a study comparing how different strains move through mixed populations in cities.

News3D models provide unprecedented look at corals’ response to bleaching events
A new study provides a first-of-its-kind glimpse into coral ‘bleaching’ responses to stress, using imaging technology to pinpoint coral survival rates following multiple bleaching events off the island of Maui.
