Water molecules identified on asteroids for the first time

Asteroids are notoriously difficult to study in detail from afar — hence the well-deserved celebration when material is brought back to Earth for analysis. But now, scientists have for the first time identified water molecules on two supposedly “dry” main-belt asteroids, 7 Iris and 20 Massalia, using data from a now-retired airborne telescope. “We detectedContinue reading "Water molecules...

Climate indices and precipitation anomalies reveal stark implications for the Middle East

A new study led by Dr. Assaf Hochman from the Institute of Earth Sciences at the Hebrew University of Jerusalem sheds light on the complex dynamics of sub-seasonal precipitation anomalies in the Middle East, revealing significant correlations with key climate indices. The research offers valuable insights into the predictability of rainfall patterns crucial for both society and the environment.

Saturn's largest moon most likely uninhabitable

A study led by Western astrobiologist Catherine Neish shows the subsurface ocean of Titan—the largest moon of Saturn—is most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead in the water.

New year brought increased consumer interest in food and nutrition resolutions

Food or nutrition-related New Year's resolutions were more popular among consumers going into 2024 compared to last year, according to the January Consumer Food Insights Report. This year 25% of consumers responded "yes" when asked if they had any food- or nutrition-related New Year's resolutions, up 6 percentage points from the response to the same question last year.

New NASA mission will study ultraviolet sky, stars, stellar explosions

As NASA explores the unknown in air and space, a new mission to survey ultraviolet light across the entire sky will provide the agency with more insight into how galaxies and stars evolve. The space telescope, called UVEX (UltraViolet EXplorer), is targeted to launch in 2030 as NASA's next Astrophysics Medium-Class Explorer mission.

New paths in climate change education: Drama as a key to change?

Given the pressing challenges of climate change, education is increasingly seen as a key to transformative adaptation to a changing environment. A study, conducted in collaboration between the Leibniz Center for Agricultural Landscape Research (ZALF) and the University of Victoria (Canada), takes a closer look at an innovative approach: the use of drama in climate change education.

Super-resolution microscopy harnesses digital display technology

In the ever-evolving realm of microscopy, recent years have witnessed remarkable strides in both hardware and algorithms, propelling our ability to explore the infinitesimal wonders of life. However, the journey towards three-dimensional structured illumination microscopy (3DSIM) has been hampered by challenges arising from the speed and intricacy of polarization modulation.

Dairy cows fed botanicals-supplemented diets use energy more efficiently

Supplementing the feed of high-producing dairy cows with the botanical extract capsicum oleoresin, obtained from chili peppers, or a combination of that extract and clove oil resulted in the animals using feed energy more efficiently and emitting less methane from their largest stomach, according to a new study conducted by Penn State researchers.

Introducing competition between schools involves a lot of work and major costs, Swedish study shows

After the introduction of the freedom to choose between upper secondary schools in 1992, it took nearly 10 years for upper secondary school heads in a municipality to start seeing themselves as competitors for school students. Any analysis of change from a later perspective needs to bear in mind that a transition of this kind takes a good deal of organizing, costs a lot of money and takes many...

Climate Change Will Make Locust Outbreaks ‘Increasingly Hard to Prevent and Control’

Extreme wind and rain may lead to bigger and worse desert locust outbreaks, with human-caused climate change likely to intensify the weather patterns and cause higher outbreak risks, a new study has found. The desert locust — a short-horned species found in some dry areas of northern and eastern Africa, the Middle East, and South Asia — is a migratory insect that travels in...

Case study: The evolution of a series of participant-centered workshops

Ludmila Tyler, senior lecturer in the biochemistry and molecular biology (BMB) department, is co-first author of a paper in the journal Biochemistry and Molecular Biology Education that reflects on the lessons learned from the first full year of Inclusive Community for the Assessment of Biochemistry and Molecular Biology/BMB Learning (ICABL) workshops.

Thermally engineering templates for highly ordered self-assembled materials

Self-assembled solidifying eutectic materials directed by a template with miniature features demonstrate unique microstructures and patterns as a result of diffusion and thermal gradients caused by the template. Despite the template trying to force the material to solidify into a regular pattern, when the template carries a lot of heat it also can interfere with the solidification process and...
