NASA’s Largest and Most Powerful Telescope Launches
On December 25, the largest and most powerful space telescope ever constructed by NASA was successfully launched from Earth. With unprecedented technology, the James Webb Space Telescope (JWST) will peer both near and far, from the planets and bodies in our solar system to the deepest reaches of space, where the first stars and galaxies formed more than 13 billion years ago.

’Pop-up’ Electronic Sensors Could Detect When Individual Heart Cells Misbehave
Engineers at the University of California San Diego have developed a powerful new tool that monitors the electrical activity inside heart cells, using tiny "pop-up" sensors that poke into cells without damaging them. The device directly measures the movement and speed of electrical signals traveling within a single heart cell—a first—as well as between multiple heart cells.

Populations of peninsular spiders that make aerial spider webs and move around the air by ballooning (using the silk threads as parachutes) present a more homogeneous genetics structure and are better connected between them. However, species of nocturnal spiders, which hunt on the ground and have a low dispersal capacity, show less genetically connected populations and are more vulnerable to local extinction processes due to environmental factors.
Spray-on coating could make solar panels snow-resistant
In an advance that could dramatically improve the productivity of solar panels in cold climates, a University of Michigan-led team has demonstrated an inexpensive, clear coating that reduced snow and ice accumulation on solar panels, enabling them to generate up to 85% more energy in early testing. The coating is made chiefly of PVC or PDMS plastic and silicon or vegetable-based oils.

Dealing with our climate crisis continues to be top of mind, although batteries, magnets, and exotic elements also captured the imagination While the COVID-19 pandemic continued to be ubiquitous in science headlines in 2021, the urgency of the ongoing climate crisis became impossible to ignore. The Intergovernmental Panel on Climate Change released its Sixth Assessment Report and world leaders gathered in Glasgow for a climate summit to negotiate how they will cut emissions.
Botox Injections May Reduce Anxiety
FDA database of drug side effects indicates the benefit may hold up no matter where Botox is injected Botox, or Botulinum toxin, a medication derived from a bacterial toxin, is commonly injected to ease wrinkles, migraines, muscle spasms, excessive sweating and incontinence.

Automating Engineering’s Ideal Manager
Engineering is a collaborative practice, but effective teamwork can take many different forms. For some projects, teamwork means accomplishing all tasks as a group; for other projects, it is better for everyone to work individually before connecting their pieces like a puzzle.

The systematic review incorporated 34,546 pregnancies and highlighted that supporting mums-to-be with a structured, healthy lifestyle program that provides structured, evidence-based health information, advice and guidance from professionals about healthy eating and physical activity during this priority life stage, helps achieve a healthier pregnancy and significantly improves pregnancy complications.
UC San Diego Researchers Take a Digital Snapshot of an Ancient Infant Burial Site
Researchers based at the UC San Diego Qualcomm Institute (QI) and Jacobs School of Engineering have digitally recreated, in painstaking detail, the oldest documented European burial of an infant female. The interactive 3D excavation site, included last week in an article with Scientific Reports (Nature) , is being used by an international team to learn more about burial practices, gender-based status and other social behaviors of ancient hunter-gatherer groups.

Animal cells are bound by a structure called a cell cortex-and this structure, researchers say, is a bit like a tent. A tent is constructed of a shell with a zippered opening that controls what can go into and out of the tent. This shell is held up by a system of poles. Similarly, an animal cell cortex is composed of a cell membrane that controls what enters the cell.
Berkeley Lab scientists vital to UC Berkeley-led work on microbial "community editing" Adapted from a UC Berkeley news release To date, CRISPR enzymes have been used to edit the genomes of one type of cell at a time: They cut, delete, or add genes to a specific kind of cell within a tissue or organ, for example, or to one kind of microbe growing in isolation in a test tube.
This Researchers have developed a new technique that images every pigment cell of a whole zebrafish in 3D. The work, recently reported in the journal eLife , could help scientists understand the role of melanin in skin cancer. Melanin is a natural pigment that gives color to the skin, hair, and eyes in humans and animals.
New Techno-Economic Model Optimizes Waste-Heat Conversion Technologies
Berkeley Lab researchers identify minimum temperature to cost-effectively generate electricity from waste heat Waste-heat power could play a significant role in decarbonizing the industrial sector due to the high-temperature of the waste heat source and the high percentage of time that the waste heat source is available.

If the perspective of space and time is not properly applied to plant research, the understanding of biological processes is limited as well as the response to the threats that endanger the life of plants worldwide. This is one of the main conclusions of an article published in the journal Trends in Plant Science by Professor Sergi Munné-Bosch, from the Faculty of Biology , the Biodiversity Research Institute ( IRBio ) and the Institute for Nutrition and Food Safety ( INSA ) of the UB.
A Yale-led team of chemists has unveiled the blueprints for a key enzyme that may contain design principles for a new generation of synthetic solar fuel catalysts. The research, led by Yale's Gary Brudvig and Christopher Gisriel, uses cryo-electron microscopy on a microorganism called Synechocystis to get an extreme close-up picture of Photosystem II, the enzyme in photosynthesis that uses water as a solar fuel, enabling researchers to observe how the enzyme works.
Nuclear ’shadow corrosion’ reproduced in the lab, paving way to longer fuel life
Now that it's understood, researchers are on their way to preventing this type of degradation in nuclear power plants Solutions to a 55-year-old problem in boiling water reactors-which represent a third of nuclear power reactors in the United States-are on the way now that the problem has been emulated with ion beams.

Dying in the desert: How U.S. border policies contribute to migrant mortality
A 5-year-old child will probably die first. Then a nonpregnant woman, followed by a grown man and finally a pregnant woman. This macabre list isn't some analysis of horror films — it's an all-too-real ranking of how likely migrants are to perish from dehydration and exposure as they traverse the most unforgiving routes through the Sonoran Desert near the Mexico-Arizona border.

UB researchers have written, required by the Spanish Ministry of Home Affairs, a report on sexual violence in Spain which gathers and analyses the existing data in order to provide a global view of the phenomenon. The authors of the study used official figures, such as the number of reports and sentences, and several published surveys and researches on this issue, among other sources.
Discovery significantly improves stability in ethylene and hydrogen production via artificial photosynthesis A research team has developed a new artificial photosynthesis DEVICE COMPONENT with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels - ethylene and hydrogen.
Pledges made in Glasgow at the recent United Nations Climate Change Conference, or COP26, are urgently needed by communities on the front lines of forest loss, according to a new study by a multidisciplinary team from the University of Washington, Duke University and The Nature Conservancy. New research shows how much local temperature rises in the tropics - compounded by accelerating deforestation - may already be jeopardizing the well-being and productivity of outdoor workers.
