Life’s rich pattern: Researchers use sound to shape the future of printing

Researchers in the UK have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.

The scientists from the Universities of Bath and Bristol have shown that it’s possible to create precise, pre-determined patterns on surfaces from aerosol droplets or particles, using computer-controlled ultrasound. A paper describing the entirely new technique, called ‘sonolithography’, is published in Advanced Materials Technologies.

Professor Mike Fraser from the Department of Computer Science at the University of Bath, explained: “The power of ultrasound has already been shown to levitate small particles. We are excited to have hugely expanded the range of applications by patterning dense clouds of material in air at scale and being able to algorithmically control how the material settles into shapes.”

Scientists grow human-Neanderthal hybrid ‘minibrains’ in petri dishes

Sesame seed-size brains created from a mix of human and Neanderthal genes lived briefly in petri dishes in a University of California, San Diego laboratory, offering tantalizing clues as to how the organs have evolved over millennia.

Scientists have long wondered how human beings evolved to have such big, complex brains. One way to figure that out is by comparing modern genes involved in brain development with those found in our ancient cousins. Though scientists have found plenty of fossilized remains from Neanderthals — cousins of modern humans that died out about 37000 years ago — they have yet to find a preserved Neanderthal brain. To bridge that gap in knowledge, a research team grew tiny, unconscious “minibrains” in petri dishes. Some of the brains were grown using standard human genes, and others were altered using the gene-editing tool CRISPR to have a brain development gene taken from Neanderthal remains.

New brain imaging research sheds light on the neural underpinnings of emotional intelligence

Recently published neuroimaging research provides evidence that the directional connectivity between several brain regions plays an important role in emotional processing abilities.

Although interest in emotional intelligence has been steadily growing since the 1990s, the underlying neural mechanisms behind it have yet to be clearly established. The new study, which appears in NeuroImage, is part of a process to begin to fill in this gap in scientific knowledge.

“Emotional intelligence is one of the least studied topics, especially in conjunction with cutting-edge computational neuroimaging techniques,” explained lead researcher Sahil Bajaj, the director of the Multimodal Clinical Neuroimaging Laboratory at Boys Town National Research Hospital.

The Dalai Lama Gets A COVID-19 Shot And Urges Others To Get Vaccinated

Updated at 2:12 p.m. ET

The Dalai Lama, the exiled Tibetan spiritual leader, left his home on Saturday to receive his first dose of the COVID-19 vaccine and promote vaccination against the coronavirus, in what was his first public appearance in over a year.

The 85-year-old scrapped plans to receive the injection at home, opting instead to travel to a clinic in Dharamsala, India, where he’s lived since fleeing China after a failed uprising in 1959.

Christopher Kennedy — Top Box Foods — Year Round Access To Nutritious Foods, In Food Insecure Areas

Mr. — Chairman, Joseph P. Kennedy Enterprises — Our discussion starts out on U.S. food insecurity, but journeys into the topics of aging, as well as regeneration research at University of Chicago’s MBL.

A “food desert” is an area that has limited access to affordable and nutritious food, and the designation considers both the type and quality of food available, as well as the accessibility of the food through the size and proximity of the food stores.

In 2010, the United States Department of Agriculture reported that 23.5 million people in the U.S. lived in food deserts, meaning that they live more than one mile from a supermarket in urban or suburban areas and more than 10 miles from a supermarket in rural areas.

Food deserts tend to be inhabited by lower-income residents with reduced mobility, making them a less attractive market for large supermarket chains and available foods are often of the highly processed type, high in sugars and fats, which are known contributors to the proliferation of obesity and other chronic diseases. It’s estimated that the contribution of food deserts to healthcare costs in the U.S. is over $70 billion annually.

Top Box Foods is a non-profit, community-based, social business, with an innovative model of getting healthy and affordable grocery boxes to food-insecure neighborhoods, creating year round access to fresh fruits, vegetables, and proteins, in communities in Chicago, and Lake County, IL, as well as in New Orleans, LA.

A New Way to Halt Excessive Inflammation

Summary: The protein Arginase-2 works through mitochondria to reduce inflammation. The findings could lead to new treatments for diseases associated with neuroinflammation, including multiple sclerosis and rheumatoid arthritis.

RCSI researchers have discovered a new way to ‘put the brakes’ on excessive inflammation by regulating a type of white blood cell that is critical for our immune system.

Unexpected discovery about stem cell immortality study

“An exciting outcome of this research is that it definitively shows the critical protective element at chromosome ends is the telomere DNA loop,” said Associate Professor Cesare.

“This likely explains why telomere length regulates ageing; cells must need long enough telomeres to make the DNA loops and this becomes difficult as cells age.”

Telomeres are the protective caps at chromosome ends. In adult cells, telomeres shorten each time a cell divides and this contributes to ageing and cancer. Pluripotent stem cells, however, are specialised cells that exist in the earliest days of development. These pluripotent cells do not age and have the ability to turn into any type of adult cell.

The surprise finding, published today in Nature, shows that telomeres in pluripotent stem cells are protected very differently than telomeres in adult tissues.

“This upends 20 years of thinking on how stem cells protect their DNA,” said Associate Professor Tony Cesare, from the University of Sydney’s Faculty of Medicine and Health, who is Head of the Genome Integrity Unit at Children’s Medical Research Institute (CMRI) and co-leader of a research team that collaborated on this research.

Election posters in Stuttgart with our advisory board member Aubrey de Grey for the state election in Baden-Württemberg on march 14th 2021

The Partei für Gesundheitsforschung (German Party for Health Research) demands, that the state should invest about 5 billion Euro per year additionally into biomedical research to hasten the development of effective medicine against the diseases of old age.

Here is our election program in German: https://parteifuergesundheitsforschung.de/wahlprogramm-der-p…erttemberg.

Please also consider donating money to the party, so that we can participate in more future elections. To participate in this years federal election in 12 states we would need e.g. at least about 50.000 Euro and unfortunately the party has almost no money at the moment. Election campaigns are a very good way to do advocacy for our cause and we can reach a lot of people this way, that we otherwise wouldn’t reach. Donating details: https://parteifuergesundheitsforschung.de/donate.

Seven scientific sectors to get extra funds as China pushes for global standing

Integrated circuits, brain sciences, genetics and biotechnology, clinical medicine and health care, and deep Earth, sea, space and polar exploration were named as the other five sectors that will be given priority in terms of funding and resources, according to a draft of the government’s 14th five-year plan for 2021–25, and its vision through 2035.

‘Basic research is the wellspring of scientific and technological innovation, so we’ll boost spending in this area by a considerable sum,’ Premier Li Keqiang says.
