A new study shows how using drones with advanced cameras, ones that detect both heat and light, can help scientists better measure how field-grown wheat plants cope with climate change. By flying these drones over hundreds of wheat varieties, researchers could estimate key traits like how efficiently the plants breathe through their leaves, how leafy they are, and how much chlorophyll they have. They then matched these traits to specific genes in the wheat, identifying genetic markers linked to better performance under normal and dry conditions. ...

Scientists have discovered a range of ‘biomarkers’ that could help to improve detection and treatment of gastrointestinal diseases (GIDs) such as gastric cancer (GC), colorectal cancer (CRC), and inflammatory bowel disease (IBD). Researchers found that certain gut bacteria and metabolites are linked to each disease - suggesting that these biomarkers could help in early, less invasive diagnosis of GIDs, with some markers indicating risk across multiple diseases. They used advanced machine learning and AI-based ...

Mechanoluminescence (ML) is a type of luminescence that occurs when a material emits light in response to an external mechanical stimulus, such as scratching, pressing, or stretching. Unlike electroluminescence (EL) or photoluminescence (PL), ML does not require an electric energy or light excitation; instead, it directly converts mechanical energy into optical emission. Then, devices fabricated from ML materials are inherently passive. This characteristic represents an intelligent and energy-efficient light-emission mode. However, most current ML research mainly focuses on the study of single-matrix materials, whose stress-induced ...

Numbers have a funny way about them. Young math students are taught various strategies to make problem-solving easier. Comparing fractions? Find a common denominator or convert to decimals. The strategies get more complex when doing the kind of math used to describe the activities of DNA, RNA, or protein sequences. In science, when you make a model, its parameters determine its predictions. But what do you do when different sets of parameters result in the same predictions? Call one half 2/4 or 3/6—either way, the result’s the same. In physics, such parameter sets are called gauge freedoms. They play a key role in how we understand electromagnetism and quantum mechanics. Surprisingly, ...

It's tempting to think that, with our fancy electric lights and indoor bedrooms, humanity has evolved beyond the natural influence of sunlight when it comes to our sleep routines.  But new research from the University of Michigan shows that our circadian rhythms are still wild at heart, tracking the seasonal changes in daylight. "Humans really are seasonal, even though we might not want to admit that in our modern context," said study author Ruby Kim, U-M postdoctoral assistant professor of mathematics. "Day ...

Research Highlights: An analysis of data from a national health survey conducted before the pandemic found that pizza, soup and chicken are some of the main sources of sodium (salt) intake for people in all racial and ethnic groups. The study also showed clear differences among adults based on race and ethnicity. Asian American adults were more likely to add salt in cooking than white adults, Black adults and Mexican American adults. However, Asian Americans were the least likely group to add salt to their food at the table. In addition, Black adults reported the highest rates of attempting to reduce salt ...

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life. Scientists believe that, in the earliest life forms, genetic material would have been carried and replicated by strands of RNA, before DNA and proteins later emerged and took over. Yet getting strands of RNA to replicate in the lab in a simple way – i.e., that plausibly could have occurred at the outset of life – has proved challenging. RNA strands zip up into a double helix that blocks their replication. Like velcro, these are ...

The combination of Rapamycin and Trametinib extends the lifespan of mice by around 30% and works better than either of the drugs alone. The therapy reduces chronic inflammation and delays cancer development New mechanisms: The combination influences gene expression differently than the individual drugs, without additional side effects. The researchers were able to show that Trametinib alone extends the lifespan of mice by 5-10%, while Rapamycin alone increases lifespan by 15-20%. Together, the drugs have a combinatorial effect that extends the life of the mice by around 30%. The ...

Close to five million smuggled seahorses worth an estimated CAD$29 million were seized by authorities over a 10-year span, according to a new study that warns the scale of the trade is far larger than current data suggest. Published today in Conservation Biology, the study analyzed online seizure records from 2010 to 2021 and found smuggling incidents in 62 countries, with dried seahorses, widely used in traditional medicine, most commonly intercepted at airports in passenger baggage or shipped in sea cargo. “The nearly 300 seizures we analyzed were based only on online records and voluntary disclosures ...

Good indoor air quality is a basic prerequisite for human health and is crucial for the ability to concentrate at work, or while studying. A nationwide study by Graz University of Technology (TU Graz) has now shown that most Austrian schools do not comply with national and European guidelines on ventilation. In the past school year, the guideline value for the daily average CO2 concentration of 1000 ppm was exceeded in 75 per cent of the classrooms examined. In winter, the rate even rose to 88 per cent. In individual cases, the average ...

Many parents know that infants love to be sung to; however, there is limited prior research to show the long-term effects on parental singing. In a new study, researchers explored whether using a music enrichment intervention program to encourage parents to sing more frequently to their babies could improve the health of both infants and caregivers (as with skin-to-contact). This research was featured in a new Child Development article with authors from Yale University (United States), the University of Amsterdam (the Netherlands), the University of Auckland (New Zealand), McGill University (Canada), Donald and Barbara Zucker School of Medicine at Hofstra/Northwell (United States) ...

Plants mastered the art of harvesting sunlight billions of years ago, using elegant rings of pigments in their leaves. Now, researchers from Osaka Metropolitan University have taken a major step toward mimicking that leafy architecture with human-made molecules that self-assemble into stacked rings where charge and energy can circulate freely — just like in photosynthesis. Their design paves the way for new approaches to light capture, energy transport and next-generation electronics. In photosynthetic organisms, pigment molecules form ...

Ever since a few enterprising bed bugs hopped off a bat and attached themselves to a Neanderthal walking out of a cave 60,000 years ago, bed bugs have enjoyed a thriving relationship with their human hosts.  Not so for the unadventurous bed bugs that stayed with the bats — their populations have continued to decline since the Last Glacial Maximum, also known as the ice age, which was about 20,000 years ago. A team led by two Virginia Tech researchers recently compared the whole genome sequence of these two genetically distinct lineages of bed bugs. Published in Biology Letters on ...
