A new study of gene expression in sponges reveals the complex diversity of their cells as well as some possibly ancient connections between the nervous, immune and digestive systems.
Great video of vital biomolecular processes.
COVID-19 mRNA vaccines deliver directions to make a protein that educates our immune system, so it will neutralize the virus in future encounters. The mRNA-containing lipid particles are taken up by specialized immune system cells. See more: COVIDVaccineAnswers.org

The Vaccine Makers Project (VMP) is the classroom-based program of the Vaccine Education Center at the Childrenâs Hospital of Philadelphia (VEC at CHOP). The Centerâs team is composed of scientists, physicians, mothers and fathers devoted to the study and prevention of infectious diseases. The Center was launched in October 2000 to provide accurate, comprehensive and up-to-date information about vaccines and the diseases they prevent. The VMP program is committed to public education about vaccine science via scientifically supported, historically accurate, and emotionally compelling content.
In one of the mysteries of mammalian development, every cell in the early female embryo shuts down one of its two copies of the X chromosome, leaving just one functional. For years, the mechanics behind this X chromosome inactivation have been murky, but scientists from the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have now taken a major step forward in understanding the process.
Their findings, based on research on mouse stem cells, upend previous assumptions about how X inactivation is initiated in female embryos and could lead to new ways to treat some genetic disorders, as well as a better understanding of how genes on other chromosomes are silenced.
âX inactivation is one of the most fundamentally important processes in development, and I think this study is a slam dunk in finally understanding it,â said Kathrin Plath, a professor of biological chemistry and senior author of the paper, published in the journal Cell.
âShark Tankâ investor Kevin OâLeary defended Tesla CEO Elon Muskâs massive fortune in an interview on âReal Time with Bill Maherâ on Saturday.
The OâLeary Funds boss â whose nickname is âMr Wonderfulâ â also attributed the recent surge in asset prices to aggressive fiscal stimulus, and predicted that many people who worked from home during the pandemic wonât return to their companiesâ offices.
Taking a daily multivitamin for 3 years is associated with a 60% slower cognitive aging, with the effects particularly pronounced in patients with cardiovascular (CVD) disease, new research suggests.
In addition to testing the effect of a daily multivitamin on cognition, the COSMOS-Mind study also examined the effect of cocoa flavonols, but showed no beneficial effect.
The results âmay have important public health implications, particularly for brain health, given the availability of multivitamins and minerals and their low cost and safety,â said research researcher Laura D. Baker, PhD, professor, Gerontology and Geriatric Medicine, Wake Forest School of Medicine, Winston-Salem, North Carolina.
Unusual clusters on neurons are calcium-signaling âhotspotsâ that activate gene transcription, allowing neurons to produce crucial proteins.
For 30 years, mysterious clusters of proteins found on the cell body of neurons in the hippocampus, a part of the brain, both intrigued and baffled James Trimmer.
Now, the distinguished professor of physiology and membrane biology at the UC Davis School of Medicine may finally have an answer. In a new study published in PNAS, Trimmer and his colleagues reveal these protein clusters are calcium signaling âhotspotsâ in the neuron that play a crucial role in activating gene transcription.
With advancements in the field of robotics, scientists have created smart soft robots that can mimic any animal in terms of movement and behaviour. This may be the future of robotics since any kind of animals, whether itâs a robot dog, cat or fish can easily be built to perform complex movements and actions to help researchers and people in need of a social companion or pet.
Soft robotics is the specific sub-field of robotics dealing with constructing robots from highly compliant materials, similar to those found in living organisms.
Soft robotics draws heavily from the way in which living organisms move and adapt to their surroundings. In contrast to robots built from rigid materials, soft robots allow for increased flexibility and adaptability for accomplishing tasks, as well as improved safety when working around humans. These characteristics allow for its potential use in the fields of medicine and manufacturing.

The TechCrunch Global Affairs Project examines the increasingly intertwined relationship between the tech sector and global politics.
Criminals have a long history of conducting cyber espionage on Chinaâs behalf. Protected from prosecution by their affiliation with Chinaâs Ministry of State Security (MSS), criminals turned government hackers conduct many of Chinaâs espionage operations. Alarming as it may sound, this is not a new phenomenon. An indictment issued by the U.S. Department of Justice last year, for example, indicated that the simultaneous criminal-espionage activity of two Chinese hackers went back as far as 2009. In another case, FireEye, a cybersecurity company, alleges that APT41, a separate cohort of MSS hackers, began as a criminal outfit in 2012 and transitioned to concurrently conducting state espionage from 2014 onward. But thereâs reason to believe that since then, China has been laying the groundwork for change.
A spate of policies beginning in 2015 put China in a position to replace contracted criminals with new blood from universities. The CCPâs first effort in 2015 was to standardize university cybersecurity degrees by taking inspiration from the United Statesâ National Initiative for Cybersecurity Education â a NIST framework for improving the U.S. talent pipeline. One year later, China announced the construction of a new National Cybersecurity Talent and Innovation Base in Wuhan. Including all of the Baseâs components, it is capable of training and certifying 70,000 people a year in cybersecurity.
Pfizer has pledged a shipment of its experimental antiviral COVID-19 pill to Israel, according to a Saturday television report, a week after the US drugmaker said it was engaged in âactive discussionâ with 90 countries regarding the coronavirus medication.
Prime Minister Naftali Bennett and Health Minister Nitzan Horowitz reached an agreement with the drug company for tens of thousands of doses, Channel 12 news reported. The shipment will be despatched as soon as Pfizer receives FDA approval for the pill, the TV report said.
PM and health minister reach agreement with drug company for âtens of thousands of dosesâ; initial data shows almost 90% efficacy.
