Researchers discover new pathway to cancer cell suicide
Chemotherapy kills cancer cells. But the way these cells die appears to be different than previously understood. Researchers from the Netherlands Cancer Institute, led by Thijn Brummelkamp, have uncovered a completely new way in which cancer cells die: due to the Schlafen11 gene. "This is a very unexpected finding. Cancer patients have been treated with chemotherapy for almost a century, but this route to cell death has never been observed before. Where and when this occurs in patients will need to be further investigated. This discovery could ultimately have implications for the treatment of cancer patients." They publish their ...

New gene delivery vehicle shows promise for human brain gene therapy
2024-05-16
In an important step toward more effective gene therapies for brain diseases, researchers from the Broad Institute of MIT and Harvard have engineered a gene-delivery vehicle that uses a human protein to efficiently cross the blood-brain barrier and deliver a disease-relevant gene to the brain in mice expressing the human protein. Because the vehicle binds to a well-studied protein in the blood-brain barrier, the scientists say it has a good chance at working in patients.
Gene therapy could potentially treat a range of severe genetic brain disorders, which currently ...
Finding quantum order in chaos
2024-05-16
If you zoom in on a chemical reaction to the quantum level, you’ll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationships and exist in multiple states simultaneously; this is akin to all parts of a wave being synchronized. It has been an open question whether quantum coherence can persist through a chemical reaction where bonds dynamically break and form.
Now, for the first time, a team of Harvard scientists has demonstrated the survival of quantum coherence in a chemical reaction involving ultracold molecules. These findings highlight the potential of ...

Building a better sarcasm detector #ASA186
2024-05-16
OTTAWA, Ontario, May 16, 2024 – Oscar Wilde once said that sarcasm was the lowest form of wit, but the highest form of intelligence. Perhaps that is due to how difficult it is to use and understand. Sarcasm is notoriously tricky to convey through text — even in person, it can be easily misinterpreted. The subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools.
Xiyuan Gao, Shekhar Nayak, and Matt Coler of Speech Technology Lab at the University of Groningen, Campus Fryslân developed a multimodal algorithm ...
Natural toxins in food: Many people are not aware of the health risks
2024-05-16
Many people are concerned about residues of chemicals, contaminants or microplastics in their food. However, it is less well known that many foods also contain toxins of completely natural origin. These are often chemical compounds that plants use to ward off predators such as insects or microorganisms. These substances are found in beans and potatoes, for example, and can pose potential health risks. However, according to a recent representative survey by the German Federal Institute for Risk Assessment (BfR), only just under half of the respondents (47 per cent) were even aware of plant toxic substances. The BfR Consumer Monitor Special on naturally occurring plant toxins ...
Archaeology: Egyptian pyramids built along long-lost Ahramat branch of the Nile
2024-05-16
31 pyramids in Egypt, including the Giza pyramid complex, may originally have been built along a 64-km-long branch of the river Nile which has long since been buried beneath farmland and desert. The findings, reported in a paper in Communications Earth & Environment, could explain why these pyramids are concentrated in what is now a narrow, inhospitable desert strip.
The Egyptian pyramid fields between Giza and Lisht, built over a nearly 1,000-year period starting approximately 4,700 years ago, now sit on the edge of the inhospitable Western Desert, part of the Sahara. ...

Listening to muscles
2024-05-16
Spinal muscular atrophy or “SMA” for short is a terrible disease in which a genetic mutation causes certain nerves responsible for sending signals to muscles to degenerate. This leads to muscles wasting away, and many patients have died a painful death due to this rare condition. Genetic treatments have only been available for a few years. Now, a team led by Emmanuel Nedoschill, Ferdinand Knieling and Adrian Regensburger from the “Translational Pediatrics” working group at the Department of Pediatrics and Adolescent Medicine at Uniklinikum Erlangen have devised ...
Spider silk sound system #ASA186
2024-05-16
OTTAWA, Ontario, May 16, 2024 – The best microphone in the world might have an unexpected source: spider silk. Spiders weave webs to trap their insect snacks, but the sticky strands also help spiders hear. Unlike human eardrums and conventional microphones that detect sound pressure waves, spider silk responds to changes in the velocities of air particles as they are thrust about by a sound field. This sound velocity detection method remains largely underexplored compared to pressure sensing, but it holds great potential for high-sensitivity, long-distance sound detection.
