Mangrove trees inspire thermal and membrane-based desalination system.
Four US students, taking part in a program aimed at high school girls interested in engineering, have designed a desalinating water bottle. The currently hypothetical device would be compact and portable so could offer increased accessibility over existing desalinating designs that mimic transpiration.
Laurel Hudson, Gracie Cornish, Kathleen Troy and Maia Vollen met at Virginia Tech’s C-Tech2 program where they were given an assignment to ‘reinvent the wheel’. Choosing to focus on the global water crisis and inspired by drinking straws used by hikers to purify water, they considered if it was possible to make a bottle that produced drinking water from seawater. They reached out to Jonathan Boreyko, an associate professor in the department of mechanical engineering, who was researching synthetic trees at the time. He agreed to help, and, during the height of the Covid-19 pandemic, the group met virtually at night to discuss their research. Along with Ndidi Eyegheleme, a graduate student in Boreyko’s lab, they planned and produced a model to evaluate the inner workings of their design.

Nearly 60% of adults and 75% of children have antibodies indicating that they’ve been infected with Covid-19, according to new data from the US Centers for Disease Control and Prevention.
The data come from an ongoing study of blood samples sent to commercial laboratories across the US.
At the beginning of December, an estimated 34% of Americans had antibodies showing that they had once been infected with the virus that causes Covid-19. By the end of February, after an avalanche of cases caused by the Omicron variant, that number had jumped to 58%.

These key building blocks of life were found in space rocks, scientists confirm.
Key building blocks of DNA that previous research mysteriously failed to discover in meteorites have now been discovered in space rocks, suggesting that cosmic impacts might once have helped deliver these vital ingredients of life to ancient Earth.
DNA is made of four main building blocks — nucleobases called adenine (A), thymine (T), cytosine © and guanine (G). DNA’s sister molecule, RNA, also uses A, C and G, but swaps out thymine for uracil (U). Scientists wondering whether meteorites might have helped deliver these compounds to Earth have previously looked for nucleobases in space rocks, but until now, scientists had only detected A and G in space rocks, and not T, C or U.
We all know man-made chemicals are damaging ecosystems across the planet. But could certain chemicals also be negatively affecting human fertility?
Dr Shanna Swan, an environmental and reproductive epidemiologist at Mount Sinai Hospital in New York and the author of Count Down, predicts that current trends could not continue much longer without threatening human survival.

Notes from Dr. Burzynski:
1. Cancer is the disease of information processing which I described in the article in.
1986.
At the Max Rady College of Medicine, University of Manitoba, in Canada, researchers have developed a stem-cell-based therapy that is regenerating spinal cords in laboratory animals and may become available for human clinical trials.
Blocking inhibitory molecules that cause neuronal cells to degenerate, and inhibit stem cell transplants may prove a breakthrough therapy.
