Trypanosomes are parasites that cause sleeping sickness, Chagas disease, and various animal diseases. Diagnosis and treatment remain complex and no effective vaccine has been developed. A better understanding of the molecular processes in the parasite is fundamental to the development of novel effective drugs. Scientists have now characterized an important protein complex -- the nuclear cap-binding complex -- that is vital for trypanosomes, since it binds to the end of... Read more ›

Transition metals have long been used as catalysts to activate small molecules and turn them into valuable products. However, as these metals can be expensive and less abundant, scientists are increasingly looking at more common elements as alternatives. In a recent study, researchers used a concept called 'frustrated Lewis pairs' to develop a transition metal-free catalyst for activating hydrogen. This breakthrough could lead to more sustainable, cost-effective, and efficient chemical... Read more ›

A new study provides compelling new evidence that a colossal 'megaflood' refilled the Mediterranean Sea, ending a period during which the Med was a vast expanse of salt flats. The study suggests the Zanclean Megaflood ended the Messinian Salinity Crisis, which lasted between 5.97 and 5.33 million years ago. Read more ›

A clinical trial demonstrates the effectiveness of telephone-delivered acceptance and commitment therapy (ACT) in reducing fatigue's interference with functioning and improving the quality of life for survivors of metastatic breast cancer. The ACT intervention helped study participants to fall asleep with greater ease. Fatigue remains a significant challenge for these survivors, affecting up to 63 percent of patients and severely impacting daily functioning. Read more ›

Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33,000 km/h, the winds make up the fastest jet-stream of its kind ever measured on a planet. The discovery provides unique insights into the weather patterns of a distant world.

Instead of relying on energy-hungry reactors to generate high temperatures and pressure, researchers are looking underground at Earth's natural heat and forces to cook up ammonia for fertilizer. In a proof-of-concept study, researchers generated ammonia by mixing nitrogen-laced water with iron-rich rocks -- without any energy input or CO2 emission. This new recipe may lead to a more sustainable alternative to current methods, theoretically churning out enough ammonia for 2.42... Read more ›

If you've ever tossed a generous pinch of salt into your pasta pan's water for flavor or as an attempt to make it boil faster, you've likely ended up with a whitish ring of deposits inside the pan. A group of scientists, inspired by this observation during an evening of board games and pasta dinner, wondered what it would take to create the most beautiful salt ring inside the pasta...

When children with obesity undergo weight-loss treatment, the effects have repercussions later in life and the risk of serious health problems and premature death is lower as they reach young adulthood. However, this is not the case for depression and anxiety, a study reports. Read more ›

Researchers present paper-based temperature and humidity sensors that are accurate, reliable, and eco-friendly. The team created the sensors by printing silver lines on commercially available paper through dry additive nanomanufacturing. As the paper absorbs water vapor, its capacitance change is measured to reflect the relative humidity of the environment, and as the temperature increases, the metallic conductor experiences an increase in resistivity. They successfully detected changes in relative humidity Read more ›

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars -- calling those assumptions into question. 'Just when you think you understand an astrophysical phenomenon, the universe turns around and surprises us,' researcher says. Read more ›

People with the skin condition psoriasis often have invisible inflammation in the small intestine with an increased propensity for 'leaky gut', according to new research. These changes in the gut could explain why psoriasis sufferers often have gastrointestinal problems and are more prone to developing Crohn's disease. Read more ›

Researchers have profiled the molecular structure and features of a key part of the deadly Nipah virus. Experiments in cells showe how changes in the viral polymerase -- a protein involved in viral replication -- can alter the virus's ability to make copies of itself and infect cells. Further analysis revealed parts of the Nipah virus polymerase that may render the pathogen susceptible to drugs. Read more ›

A new study has described a phenomenon researchers refer to as 'contagious urinations.' The study in 20 captive chimpanzees living at the Kumamoto Sanctuary in Japan shows that, when one chimp pees, others are more likely to follow. Read more ›

Researchers have determined how children's immune systems react to different kinds of cancer depending on their age. The study reveals significant differences between the immune response of children and adults, and has the potential to lead to new tailored treatments for children with cancer. Read more ›

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the 'dark side' of the genome, researchers have now revealed their crucial role in early embryo development. Read more ›
