For The Better

Bone mineral density at the femoral neck bone in postmenopausal women decreased by an average of 10% during a 25-year follow-up, according to a new study. Being the world’s hitherto longest follow-up of changes in bone mineral density in postmenopausal…

The newly hatched juveniles of large and gigantic pterosaurs likely out-competed other smaller adult pterosaur species to dominate the Late Cretaceous period around 100 million years ago, a new study has found.

Biologists have unraveled how a ‘heart’ in the fruit fly’s head functions. The researchers discovered the fly’s head-heart beats much like a human’s: Its rhythmic pulses are automatically generated by a tiny muscle that runs through the middle of the f…

Researchers tested the effectiveness of affordable, interactive robotic pet cats to improve mood, behavior and cognition in older adults with mild to moderate dementia. Mood and behavioral symptoms were measured along with cognition using the Mini Ment…

Researchers have developed a concept that would make Martian rocket fuel, on Mars, that could be used to launch future astronauts back to Earth.

How are warming temperatures and a loss of sea ice affecting polar bears and their marine mammal prey in the Arctic? A York University-led research team used a novel approach to the question by monitoring what polar bears eat across Nunavut and where t…

Research has shed new light on the way malignant cells change their shape and migration techniques to invade different types of tissue.

Biological cells invest much of their resources into the production of enzymes, which catalyze the conversion of substrates into products. An international team of bioinformaticians and biophysicists discovered that these processes are most efficient a…

Thirty years ago, archeologists excavated the tomb of an elite 40–50-year-old man from the Sicán culture of Peru, a society that predated the Incas. The man’s seated, upside-down skeleton was painted bright red, as was the gold mask covering his detac…

Some people are born with hearing loss, while others acquire it with age, infections or long-term noise exposures. In many instances, the tiny hairs in the inner ear’s cochlea that allow the brain to recognize electrical pulses as sound are damaged. As…

Scientists have developed a computer-aided data tool that could improve treatment for a range of illnesses.

A study has found that adults with maltreatment-related posttraumatic stress disorder or a history of sexual abuse have lower brain connectivity in the attention systems known as the ventral and dorsal attention network. These networks enable us to shi…

In 1545, King Henry VIII’s favorite ship, the Mary Rose, capsized and sank in the Battle of the Solent defending England and Portsmouth from a French invasion fleet. The wreck remained on the seabed until 1982 when it was salvaged in a widely viewed te…

Researchers have determined the genetic origins of Asia’s most enigmatic mummies. Once thought to be Indo-European speaking migrants from the West, the Bronze Age Tarim Basin mummies are revealed to be a local indigenous population with deep Asian root…

Research on around 386,000 UK adults has found that a high genetic risk for schizophrenia and other mental health conditions, including bipolar disorder, anorexia and autism, is associated with living in and moving to urban areas. In contrast, people w…

Space missions, such as NASA’s Orion that will take astronauts to Mars, are pushing the limits of human exploration. But during their transit, spacecrafts encounter a continuous stream of damaging cosmic radiation, which can harm or even destroy onboar…

Researchers have uncovered a striking new behavior of the ‘strange metal’ state of high temperature superconductors. The discovery represents an important piece of the puzzle for understanding these materials.

Researchers have created an innovative hybrid printing method — combining multi-material aerosol jet printing and extrusion printing — that integrates both functional and structural materials into a single streamlined printing platform.

New work reveals a new mechanism by which plants are able to rapidly activate defenses against bacterial infections. These findings could inspire efforts to improve crop yields and combat global hunger.
