New sensors could offer early detection of lung tumors
New sensors could offer early detection of lung tumors
People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers at MIT have now developed a new approach to early diagnosis of lung cancer: a urine test that can detect the presence of proteins linked to the disease.

Suspect cells' 'neighbor' implicated in colorectal cancer
Suspect cells’ ’neighbor’ implicated in colorectal cancer
Colorectal cancer kills more than 50,000 people a year in the United States alone, but scientists have struggled to find the exact mechanisms that trigger the growth of tumors in the intestine. Cancer researchers have zeroed in on a tightly sequestered group of stem cells within the intestine as suspects in the development of colon cancer but have been unable to explain exactly how genetic mutations within those stem cells can cause tumors of the digestive track.

UK genome analysis has important implications for COVID-19 clinical trials
Researchers from Bristol's School of Cellular and Molecular Medicine have been growing the live human SARS-CoV-2 virus in a controlled lab to investigate what the virus is doing inside monkey and human cells. Using state-of-the-art scientific techniques, the team isolated parts of the SARS-CoV-2 virus to find out how the virus instructs the cell to make virus proteins, which can either be used to form virus particles or slow our immune response.

About the distribution of biodiversity on our planet
About the distribution of biodiversity on our planet
Large open-water fish predators such as tunas or sharks hunt for prey more intensively in the temperate zone than near the equator. With this result, a study headed by Marius Roesti of the University of Bern is challenging a long-standing explanation for the distribution of biodiversity on our planet.

How dopamine drives brain activity
How dopamine drives brain activity
A specialized MRI sensor reveals the neurotransmitter's influence on neural activity throughout the brain. Using a specialized magnetic resonance imaging (MRI) sensor, MIT neuroscientists have discovered how dopamine released deep within the brain influences both nearby and distant brain regions. Dopamine plays many roles in the brain, most notably related to movement, motivation, and reinforcement of behavior.

Blocking the Iron Transport Could Stop Tuberculosis
Blocking the Iron Transport Could Stop Tuberculosis
The bacteria that cause tuberculosis need iron to survive. Researchers at the University of Zurich have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport into the bacteria is inhibited, the pathogen can no longer grow. This opens novel ways to develop targeted tuberculosis drugs.

Honeyeaters send lightning-fast warning signals
Honeyeaters send lightning-fast warning signals
New Holland honeyeaters are experts at sounding the alarm when there's danger, according to new research from biologists Jessica McLachlan and Rob Magrath. They found honeyeaters can spread the word in the blink of an eye, using a two-stage alarm. It's particularly effective when they are threatened by fast-moving birds of prey.

How the novel coronavirus binds to human cells
Coronaviruses infect humans by binding to specific proteins, known as receptors, on human cell surfaces. Researchers from the University of Minnesota, led by Professor Fang Li in the Department of Veterinary and Biomedical Sciences at the College of Veterinary Medicine , recently broke new ground in understanding how SARS-CoV-2, the virus that causes COVID-19, binds to its human receptor.

Key-and vulnerable-features of novel coronavirus
The novel coronavirus, SARS-CoV-2, is closely related to the SARS virus that caused devastation in 2002-03. A University of Minnesota team, led by researcher Fang Li, studied how mutations that changed the structure of a SARS-CoV-2 protein enabled it to attach more securely to human cells than its predecessor, infect human cells better, and spread faster.

Scientists document seasonal migrations of fish across the deep-sea floor for the first time
Scientists have, for the first time, documented seasonal migrations of fish across the seafloor in deep-sea fish, revealing an important insight that will further scientific understanding of the nature of our planet. The study - published today in the Journal of Animal Ecology and led by the University of Glasgow and Nova Southeastern University in Florida - analysed over seven years of deep-sea photographic data from West Africa, linking seasonal patterns in surface-ocean productivity with observed behavioural patterns of fishes at 1500 metres.

Scientists predict the size of plastics animals can eat
A team of scientists at Cardiff University has, for the first time, developed a way of predicting the size of plastics different animals are likely to ingest. The researchers, from the University's Water Research Institute, looked at the gut contents of more than 2,000 animals to create a simple equation to predict the size of a plastic item an animal can eat, based on the length of its body.

Marine species respond as oceans warm
A global analysis of over 300 marine species spanning more than 100 years, shows that mammals, plankton, fish, plants and seabirds have been changing in abundance as our climate warms. At the cool edge of species ranges marine life is doing well as warming opens up habitat that was previously inaccessible, while at the warmer edge species are declining as conditions become too warm to tolerate.

A new mechanism triggering cell death and inflammation: a left turn that kills
Z-form nucleic acids are double-stranded DNA and RNA molecules with an unusual left-handed double helix structure, as opposed to the classical right-handed Watson-Crick double helix. Z-nucleic acids were discovered more than 40 years ago, but their biological function has remained poorly understood.

Old human cells rejuvenated with stem cell technology
Old human cells can become more youthful by coaxing them to briefly express proteins used to make induced pluripotent cells, Stanford researchers and their colleagues have found. The finding may have implications for aging research. Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study by researchers at the Stanford University School of Medicine.

Urban birds need to be smart or fast-breeding
To thrive in urban environments, birds need to either have large brains, or breed many times over their life, according to a new study involving UCL. The study, published in Frontiers in Ecology and Evolution , suggests that birds have two alternative strategies for coping with the difficulties of humanity's increasingly chaotic cities.
