Leave voters in Cornwall wanted to exit the EU to "take back control" and express concern about immigration - even though most said the movement of people across the continent had not caused issues for them, a new survey suggests.

A team of Spanish researchers have developed, at the laboratory level, a prototype of a new biosensor to help detect breast cancer in its earliest stages. It is an easy-to-use, low-cost prototype of a nanoporous device, and provides results in less than an hour.

Researchers at University of California San Diego School of Medicine found that functional impairments among adults aged 50 and older are associated with a higher risk of medical cannabis use; and prescription opioid and tranquilizer/sedative use and misuse.

Astronomers using NASA's Hubble Space Telescope have traced the locations of five brief, powerful radio blasts to the spiral arms of five distant galaxies.

Building more homes and buildings with wood has been on the radar for years as a way to offset carbon emissions, though construction companies have been hesitant to take the material in broader use. A study at Aalto University in Finland is now the first to show that building with wood can be a sound investment. The findings show that multi-storied buildings made out of wood sold for an average of 8.85% more than those made from other materials.

Comets that circle the Sun in very elongated orbits spread their debris so thin along their orbit or eject it out of the solar system altogether that their meteor showers are hard to detect. From a new meteor shower survey published in the journal Icarus, researchers now report that they can detect showers from the debris in the path of comets that pass close to Earth orbit and are known to return as infrequent as once every 4,000 years.

The work is the first global assessment of Earth's 92,033 debris-covered glaciers and shows that debris, taken as a whole, substantially reduces glacier mass loss.

A new iron catalyst helps preferentially reduce nitric oxide to hydroxylamine, opening doors to pollution control and clean energy.

Sarah Buchanan, an assistant professor in the University of Missouri's College of Education, is an archivist, a professional who assesses, collects and preserves various artifacts and archives them to better understand their origin and cultural heritage.

A team of researchers at the University of Ottawa has found a way to use visible light to transform carbon dioxide gas, or CO2, into solid carbon forms that emit light. This development creates a new, low-energy CO2 reduction pathway to solid carbon that will have implications across many fields.

New research from the University of Georgia has found a narrowing but persistent gender pay gap in one of the federal government's largest agencies.

Small chemical "epigenetic" modifications help plants control their genes. Baby plants erase these modifications to start with a fresh genome every generation. CSHL scientists discovered a gene responsible for reinstalling the beneficial modifications important for survival. Reinstalling these modifications on mobile genetic elements called transposons may explain the diversity of flowering plants.

Researchers have been able to prove for the first time that activation of distinct human endogenous retroviruses, which are part of our genome, impair brain development dramatically. This finding could help to advance research into therapies for neurodegenerative diseases. The study originated from an international collaboration led by Helmholtz Zentrum München.

Researchers from the University of California, Berkeley, created a single-sided, co-planar optoelectrowetting device that allows for individualized and parallel droplet actuation and benefits from easier droplet accessibility from above for more input/output configuration schemes.

Today, proteins that can be controlled with light are a widely used tool in research to specifically switch certain functions on and off in living organisms. Channelrhodopsins are often used for the technique known as optogenetics: When exposed to light, these proteins open a pore in the cell membrane through which ions can flow in. A research team has now used spectroscopy to discover a universal functional mechanism of channelrhodopsins that determines their efficiency as a channel and thus as an optogenetic tool.

Juvenile salmon migrating to the sea in the Sacramento River face a gauntlet of hazards in an environment drastically modified by humans, especially with respect to historical patterns of stream flow. Now fisheries scientists have identified key thresholds in the relationship between stream flow and salmon survival that can serve as actionable targets for managing water resources in the Sacramento River.

A newly identified group of antibodies that binds to a coating of sugars on the outer shell of HIV is effective in neutralizing the virus and points to a novel vaccine approach that could also potentially be used against SARS-CoV-2 and fungal pathogens, researchers at the Duke Human Vaccine Institute report.

Researchers at Uppsala University have successfully sequenced the entire genome from the skull of Peştera Muierii 1, a woman who lived in today's Romania 35,000 years ago. Her high genetic diversity shows that the out of Africa migration was not the great bottleneck in human development but rather this occurred during and after the most recent Ice Age. The study is now published in Current Biology.

New research led by the University of Kent's School of Psychology has found that some brain activity methods used to detect incriminating memories do not work accurately in older adults.

Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. If applicable to other glaciers and ice sheets, the technique could allow for more accurate predictions of future sea-level rise.
