Gold and platinum offer clues about the moon's mysterious tilt

A total solar eclipse occurs somewhere on Earth about once every year and a half, on average. But imagine if it happened every single month. For this to be the case, the moon would have to orbit Earth in the same plane in which Earth travels around the sun - that way, the new moon would always come directly between us and the sun.

Scientists get first glimpse of black hole eating star, ejecting high-speed flare

An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light.

Hubble captures a galactic waltz

This curious galaxy—only known by the seemingly random jumble of letters and numbers 2MASX J16270254+4328340—has been captured by the NASA/ESA Hubble Space Telescope dancing the crazed dance of a galactic merger. The galaxy has merged with another galaxy leaving a fine mist, made of millions of stars, spewing from it in long trails.

SDO sees a dark filament circle

AugerPrime looks for cosmic superaccelerators

The Pierre Auger Observatory in Argentina, an international large-scale experiment to study cosmic rays, will be continued until 2025 and extended to "AugerPrime". The observatory, for the project management of which Karlsruhe Institute of Technology (KIT) is responsible, will be upgraded with new scintillation detectors for a more detailed measurement of gigantic air showers. This is required to identify cosmic objects that accelerate atomic particles up to highest energies.

The field is called affective computing, and soon it will be an important factor in the way people and computers communicate with each other.

Sensor detects cable fire before it starts burning

Fires are frequently caused by smoldering cables. Novel sensors now help detect such smoldering fires at an early stage by analyzing the plastic vapors released by overheated insulating cables. Scientists of KIT and Karlsruhe University of Applied Sciences have developed these hybrid sensors that combine measurement processes with data evaluation. Their work is reported in the current issue of the Sensors & Transducers Journal.

Functional human liver cells grown in the lab

In new research appearing in the prestigious journal Nature Biotechnology, an international research team led by The Hebrew University of Jerusalem describes a new technique for growing human hepatocytes in the laboratory. This groundbreaking development could help advance a variety of liver-related research and applications, from studying drug toxicity to creating bio-artificial liver support for patients awaiting transplantations.

Researchers uncover essential interaction between malaria parasites and liver cells

Scientists at the Center for Infectious Disease Research recently uncovered a critical piece in the puzzle of how malaria parasites infect their host. The work, recently published in Science Magazine, reveals the details of how the malaria parasite invades its initial target organ, the liver. Without infection of the liver, the parasites cannot multiply or spread to the blood. Infection of the blood causes illness, spread of the disease, and, ultimately, death.

Recommended activity levels not achieved by obese children and those with liver disease

What your musical taste says about your personality

We're exposed to music for nearly 20% of our waking lives. But much of our musical experience seems to be a mystery. Why does some music bring us to tears while other pieces make us dance? Why is it that the music that we like can make others agitated? And why do some people seem to have a natural ability to play music while others have difficulty carrying a tune? Science is beginning to show that these individual differences are not just random but are, in part, due to people's personalities.

Oxytocin increases social altruism

Nowadays, much emphasis is placed on sustainability. The degree to which people are willing to donate their own money for this depends on their level of oxytocin. Scientists at the University of Bonn Hospital have discovered that the willingness to donate increases with the quantity of this bonding hormone. However, oxytocin only has an effect with regard to social sustainability projects. The hormone does not increase the ability to participate in the case of purely environmentally oriented projects. The scientists are now reporting their results in The Journal of Neuroscience.

Looking on the brighter side of childhood asthma

The effect of a widespread genetic variant that increases the risk for childhood asthma can be neutralized. A new study shows that young infants are particularly responsive to the positive influence of exposure to farm dust.

Using sphere packing models to explain the structure of forests

Explaining the complex structure of tropical forests is one of the great challenges in ecology. An issue of special interest is the distribution of different sizes of trees, something which is of particular relevance for biomass estimates. A team of modellers from the Helmholtz Centre for Environmental Research (UFZ), working together with research partners, has now developed a new method which can be used to explain the tree size distribution in natural forests. To do so, the scientists use principles from stochastic geometry, as they have reported in a contribution to the Proceedings of the National Academy of Sciences (PNAS, Early Edition). Using this approach, it is possible to assess the structure of natural forests across the world more quickly, and produce more accurate biomass estimates.

Oldest known seabird is back at Midway Atoll near Hawaii
