Heparin, the world's most widely used blood thinner, is used during procedures ranging from kidney dialysis to open heart surgery. Currently, heparin is derived from pig intestines, but scientists have discovered how to make it in the lab. They have also developed a path to a biomanufacturing process that could potentially revolutionize how the world gets its supply of this crucial medicine.

A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.

Researchers have developed a new faster and cheaper method to synthesise GLP-1 receptor targeting drugs.

New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.

Researchers have identified new drug candidates for preventing and treating major respiratory viral infections.

Our eating habits in industrialized societies are far removed from those of ancient humans. This is impacting our intestinal flora, it seems, as newly discovered cellulose degrading bacteria are being lost from the human gut microbiome, especially in industrial societies.

The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.

Polyphenols, abundant in fruits, vegetables, tea, and coffee, offer potential health benefits. However, owing to low bioavailability, the mechanisms underlying their beneficial effects remain unknown. In a recent study, researchers have explored the interaction between polyphenols and human sensory receptors. Their findings elucidate how polyphenols influence brain function and metabolic pathways by interacting with gut receptors, explaining their role in well-being and nutrition innovation.

A new study shows how heteroresistance, a transient resistance common in many bacteria, can act as a precursor to the development of antibiotic resistance.

When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.

A new study found that metformin, a commonly prescribed diabetes drug associated with moderate weight loss, stimulates production of lac-phe, a molecule abundant after exercise.

Researchers have performed the most comprehensive analysis to date of cancer of the ureters or the urine-collection cavities in the kidney, known as upper tract urothelial carcinoma (UTUC). The study, which compared the characteristics of primary and metastatic tumors, provides new insights into the biology of these aggressive cancers and potential ways to treat them.

Scientists have developed the first wireless, implantable temperature sensor to detect inflammatory flareups in patients with Crohn's disease. The approach offers long-term, real-time monitoring and could enable clinicians to act earlier to prevent or limit the permanent damage caused by inflammatory episodes.

Muscle injuries are common in the active population, and they cause the majority of player leaves in the world of sport. Depending on the severity, recovery of muscle function is quite slow and may require surgery, medication and rehabilitation. Now, a study reveals a strategy to improve and accelerate recovery from muscle injuries that has potential application in the sports and health sector in general.

Venting about a source of anger might feel good in the moment, but it's not effective at reducing the rage, new research suggests. Instead, techniques often used to address stress -- deep breathing, mindfulness, meditation, yoga or even counting to 10 -- have been shown to be more effective at decreasing anger and aggression.

A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.

Scientists have discovered how female Diadem butterflies have evolved to look like African Queen butterflies to repel predators.

A global wave of infections caused by fungi growing drug-resistant has the medical community issuing precautions on how to protect yourself.

Contrary to some claims, laws that criminalize or otherwise punish drug use during pregnancy are more likely to worsen rather than improve health outcomes. The study is the first to systematically review the literature on punitive prenatal drug laws -- an increasingly common state policy strategy for addressing rising rates of prenatal drug use.

The use of antipsychotics during pregnancy isn't linked to childhood neurodevelopmental disorders or learning difficulties, study suggests -- giving assurance to those concerned about continuing their medications during pregnancy.

The curvature of a surface determines the migration behavior of biological cells. They preferentially move along valleys or grooves while avoiding ridges. These findings gave rise to a model predicting cellular behavior. Such universal principles now allow a better understanding of the migration of immune and cancer cells, paving the way for new treatment options.

Researchers have discovered that the causes of age-related memory decline are more complicated than previously believed. Their study found that neural dedifferentiation is driven by different mechanisms depending on the type of visual stimuli the brain is trying to recall.

A novel mixed light field technique that utilizes a mix of ray-controlled ambient lighting with projection mapping (PM) to obtain PM in bright surroundings has been developed by scientists. This innovative technology utilizes a novel kaleidoscope array to achieve ray-controlled lighting and a binary search algorithm for removing ambient lighting from PM targets. It provides an immersive augmented reality experience with applications in various fields.

Fatty liver, which can lead to liver damage and disease, can occur from both overeating and starvation. Now, new research shows how naturally starvation-resistant cavefish, unlike other animals, are able to protect their liver and remain healthy. The findings have implications for understanding and potentially addressing liver conditions in humans.

A new analysis estimates that 68 percent of Chicago children under age six live in households with tap water containing detectable levels of lead.
