Sweat is more than just a sign of a good workout. It holds vital information about our health, providing clues to dehydration, fatigue, blood sugar levels and even serious conditions such as cystic fibrosis, diabetes and heart failure. Researchers have taken a giant leap forward in sweat analysis with an innovative 3D-printed wearable sweat sensor called the 'sweatainer.'

A new study sheds light on how a rare type of helper T cell, called Th9, can drive allergic disease, suggesting new precision medicine approaches to treating allergies in patients with high levels of Th9.

Water can change its solubility characteristics depending upon what it interacts with.

This year and next, Americans will have the extraordinary opportunity to witness two solar eclipses as both will be visible throughout the continental U.S. Both occurrences promise to be remarkable events and teachable moments but preparation is essential. Astronomers provide a practical playbook to help teachers, students, and the general public prepare for the eclipse events.

-Electrocatalyst achieves record-breaking selectivity toward desired product, a key step in expanding production -Acetic acid, found in vinegar, is traditionally extracted from fossil fuels for use in paint and other product feedstock.

Worldwide, growers lose between 10 and 23 per cent of their crops to fungal infection each year, despite widespread use of antifungals. An additional 10-20 per cent is lost post harvest. In a commentary in Nature, academics predict those figures will worsen as global warming means fungal infections are steadily moving polewards, meaning more countries are likely to see a higher prevalence of...

ere are some scientific findings worthy of a toast: Researchers have explained why bubbles in Champagne fizz up in a straight line while bubbles in other carbonated drinks, like beer or soda, don’t.

Scientists have observed a star swallowing a planet for the first time. Earth will meet a similar fate in 5 billion years.

An international research team has for the first time successfully isolated ancient human DNA from a Paleolithic artefact: a pierced deer tooth discovered in Denisova Cave in southern Siberia. To preserve the integrity of the artefact, they developed a new, nondestructive method for isolating DNA from ancient bones and teeth. From the DNA retrieved they were able to reconstruct a precise genetic...

Traces of sex hormones extracted from a woolly mammoth's tusk provide the first direct evidence that adult males experienced musth, a testosterone-driven episode of heightened aggression against rival males, according to a new study.

A research team has developed a novel machine-learning algorithm that can reveal the hidden structure in data recorded from the brain, predicting complex information such as what mice see.

Scientists have identified a potential pathway to pain relief that neither triggers addiction nor causes hallucinations.

Immunotherapy has redefined cancer treatment, but not all patients experience the same benefit when treated. New research in mice identifies how gut bacteria alter the body's response to a common form of cancer immunotherapy. The animals' gut microbiota lowered the expression of two immune molecules, one previously unknown to play a role in cancer. • Using antibodies to block the activity of...

A new study has found links at the atomic level between photosynthesis and exciton condensates -- a strange state of physics that allows energy to flow frictionlessly through a material. The finding is scientifically intriguing and may suggest new ways to think about designing electronics, the authors said.

Researchers have developed a new high-speed way to detect the location, size and category of multiple objects without acquiring images or requiring complex scene reconstruction. Because the new approach greatly decreases the computing power necessary for object detection, it could be useful for identifying hazards while driving.

Photosynthesis plays a crucial role in shaping and sustaining life on Earth, yet many aspects of the process remain a mystery. One such mystery is how Photosystem II, a protein complex in plants, algae and cyanobacteria, harvests energy from sunlight and uses it to split water, producing the oxygen we breathe. Now researchers have succeeded in cracking a key secret of Photosystem II.

All human beings are genetically very similar, sharing approx. 99.9% of the DNA code. The remaining 0.1% explains the natural differences between people, including our predisposition to hereditary diseases. Although sequencing of our genetic material is becoming a routine diagnostic analysis, it is unfortunately far from simple to determine whether specific small differences in our DNA affect our...

A UCLA-led research team created an 'urban association index' that describes how closely bird species are associated with living in urban settings. With more of the planet being consumed by urbanization, the scientists write that a dramatic loss of biodiversity is likely unless there are practical plans to preserve it. Urban bird species tend to be smaller and less territorial and have greater...

A research group has succeeded in regulating the flow of single molecules in solution by opening and closing the nanovalve mounted on the nanofluidic device by applying external pressure. The research group fabricated a device with a ribbon-like, thin, soft glass sheet on the top, and at the bottom a hard glass substrate having nanochannels and nanovalve seats. By applying external pressure to the...

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and...

Using ESO's Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions. These findings bring us one step closer to understanding the nature of the first stars that formed after the Big Bang.

A new study shows that sleep spindles, brief bursts of brain activity occurring during one phase of sleep and captured by EEG, may regulate anxiety in people with post-traumatic stress disorder (PTSD).

If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.

A team of researchers develops stem cell adhesive for arthritis treatment using mussel adhesion protein and hyaluronic acid.
