Scientists find mechanism to reset body clock

Researchers at the University of Manchester have discovered a new mechanism that governs how body clocks react to changes in the environment. The enzyme casein kinase 1epsilon (CK1epsilon) controls how easily the body's clock can be adjusted or reset by environmental cues such as light and temperature.

Loss of biodiversity limits toxin degradation

A moderate loss of soil microbes may compromise key ecosystem functions and lower toxin degradation. Research found that specialized bacterial functions are not as effective without a rich diversity of soil bacteria.

KIT researchers develop artificial bone marrow

Researchers have created an artificial bone marrow that can reproduce hematopoietic stem cells, which could facilitate the treatment of leukemia. The new technology uses synthetic polymers and protein building blocks to mimic the natural environment of bone marrow, allowing for more efficient stem cell reproduction.

Duke wins $15 million renewal to study nanotech safety

The Center for Environmental Implications of NanoTechnology (CEINT) at Duke University has been awarded a $15 million grant renewal to continue studying the environmental impact of nanoparticles. The research focuses on understanding where nanoparticles accumulate, how they interact with other chemicals, and their effects on ecosystems.

1 worm, 2 mouths

Researchers at Max Planck Institute for Evolutionary Biology find gene eud-1 that determines wide-mouthed predators and narrow-mouthed bacteria eaters, providing insight into phenotypic plasticity. The discovery sheds light on how organisms adapt to changing environments and challenges current understanding of evolutionary adaptations.

The immune system benefits from life in the countryside

Research from Aarhus University shows that exposure to a farming environment can prevent or dampen hypersensitivities and allergies, even in adults. The study found that working in farming environments stimulates the immune system, dampening its response to environmental irritants, which may trigger hypersensitivity.

Birds outpace climate change to avoid extinction

A new study found that birds can survive climate change through phenotypic plasticity, a flexibility in behavior. This adaptation enables them to track environmental changes, increasing their chances of survival. However, slow-reproducing species are more vulnerable to extinction due to the need for precise adaptations.

Tallying the wins and losses of policy

A new study found that China's payments for ecosystem services programs led to significant forest growth and environmental benefits. However, the programs also had negative impacts on rural households and their livelihoods, highlighting the need for more sustainable policies.

When green algae run out of air

Biologists discovered that green algae require haemoglobin and nitric oxide to signal the absence of oxygen, allowing them to activate genes and produce hydrogen. In an oxygen-rich environment, this gene is idle, and its inactivation has fatal consequences for the algae.

Background noise in the operating room can impair surgical team communication

A new study found that high levels of OR noise can have a disruptive effect on a surgeon's auditory processing abilities and cause a decrease in speech comprehension. The researchers tested 15 surgeons with varying years of experience under different listening conditions, including quiet, filtered noise, background noise, and music.

Researcher offers clues on the origins of life

A three-year study by Professor Michael Blaber and his team suggests that proteins, not RNA, were the first molecules to form life. The researchers found that 10 prebiotic amino acids could be folded into complex protein structures in a high-salt environment, supporting a 'protein-first' view of abiogenesis.

Use it or lose it

A new study found that prolonged exposure to an enriched environment activates brain receptors, preventing amyloid beta protein from weakening nerve cell communication. This provides a molecular mechanism for why a richer environment can help lessen the memory-eroding effects of Alzheimer's disease.
