- Personalized metabolic program eased cognitive decline in small case series — r/longevity
The MEND program targets multiple metabolic and lifestyle factors rather than relying on a single drug. Ten patients with Alzheimer’s disease, mild cognitive impairment, or subjective cognitive impairment took part in the 2014 case series. Nine showed subjective or objective cognitive improvement within three to six months. Six patients who had stopped working or were struggling at work returned to work or improved their performance. The single patient who did not improve had very late-stage Alzheimer’s. The authors described the work as a very small preliminary case series and concluded that the promising results warranted larger studies.

The southern region of the Democratic Republic of Congo is known as the Copperbelt because of its rich deposits of copper and other minerals. A study found that cobalt exports from this area also contain unreported uranium. The presence of uranium in those exports raises questions about global nuclear risk tracking.

London has one of the lowest violent crime rates of any region in England and Wales. It tops a global ranking of the best cities and pays more in taxes than it receives back in public spending. A new study from the Policy Institute at King’s College London shows that the public overestimates how likely Londoners are to become victims of crime. The same study shows that Britons underestimate the capital’s international standing and have little idea it is the key contributor to public finances.

For decades scientists have understood proteins primarily through their amino acid sequence and three-dimensional structure. New imaging work reveals the arrangement of water molecules that surround and interact with protein surfaces. This hidden water architecture may help define how proteins function in cells.

A new database compiled by Leiden researchers tracks food-related emissions across cities. Switching to sustainable diets could halve emissions in places such as Amsterdam. In cities such as Dhaka and Delhi the priority lies in making production more sustainable while widening access. The database shows that different cities need different approaches to achieve a more sustainable food system.

Researchers at Umeå University showed that even highly antibiotic-resistant bacteria become more vulnerable when their cell-wall transport system is disrupted. The discovery reveals a previously overlooked weakness that could help researchers develop new strategies to combat antibiotic resistance.

Learning is often thought to require a brain. Bacteria demonstrate the ability to store and recall information about earlier environments in ways that resemble artificial neural networks. The work shows that learning is a broad concept that does not necessarily depend on neurons. Source: phys.org - CRISPR-Combo system accelerates regeneration of perennial crops — Phys.org
Gene editing alone does not produce a full plant from edited cells. The new CRISPR-Combo approach improves the speed and reliability of growing complete plants from edited cells in hard-to-breed perennial species. Editing a plant’s genes is only half the battle before a new trait can reach a farmer’s field. Source: phys.org - New genomic tool aids disease-resistant clam breeding — Phys.org
An international team including CIIMAR developed a new genomic resource for the Japanese clam and the good clam. The tool supports selection for disease resistance and climate tolerance while helping maintain genetic diversity in aquaculture stocks. The study was published in the journal Aquaculture.

Researchers at King Abdullah University of Science and Technology led a global assessment of oysters, mussels, crabs and similar species. The study supplies one of the most detailed pictures yet of their contribution to human nutrition. The findings also inform sustainable fisheries planning and aquaculture.

Scientists from Universitat Politècnica de Barcelona and the ESRF used synchrotron analysis to trace the chemical reactions inside nanoparticles. Those reactions created shimmering effects on ninth-century Islamic ceramics. The results appear in Science Advances.

University of East Anglia research shows that when females mate with multiple males their offspring inherit fewer deleterious genetic mutations. The reduction improves population health and lowers extinction risk. The study reveals that multiple mating can help make species more resistant to extinction.

Kinesin walks along microtubules by coordinating two motor domains. Supercomputer modeling revealed the three-dimensional structure of the neck region and how it interacts with the microtubule to keep the motor on track. The neck region is crucial for coordinating this motion. Source: phys.org - Calcium mishandling inside muscle cells drives age-related weakness — Lifespan.io
Researchers traced how disrupted calcium handling in skeletal muscle cells produces long-term loss of strength in older adults. The work links a basic cellular process to functional decline. Calcium is required for muscle contraction yet mishandling of the ion contributes to weakness over time.

As resistance to conventional antibiotics increases researchers are examining copper’s antimicrobial properties. The approach targets surface contamination and infection control in clinical settings. Copper can kill or inhibit bacteria on contact through mechanisms distinct from traditional antibiotics. Source: stories.tamu.edu
Planetterrian Spotlight
The Umeå University finding on cell-wall transport identifies a vulnerability that persists even in strains already resistant to multiple drugs. Disrupting this system could make existing antibiotics effective again without needing entirely new compounds. The work focuses on a conserved bacterial process rather than a single resistance gene, which may slow the evolution of further resistance. Future experiments will need to test whether the approach remains effective in animal models and against diverse clinical isolates. What specific components of the transport machinery look most druggable in follow-up screens?
Science Deep Dive: How Bacteria Remember Without a Brain
Most people assume that storing and acting on past experience requires neurons or at least a nervous system. Bacteria demonstrate that memory can emerge from simpler molecular circuits. Right now populations of bacteria in soil water and your own body are adjusting their behavior based on conditions they encountered hours or days earlier. Experiments show they can maintain a record of previous nutrient levels or stress signals across several generations through changes in protein concentrations and feedback loops. One memorable detail is that these cellular memories allow bacteria to anticipate recurring environmental shifts and respond faster than a naive cell would. The next time you hear claims that only brains can learn remember that the same principle of storing information in stable molecular states operates at the scale of single cells and can be studied directly in the lab. Researchers continue to map the exact molecular switches that let bacteria update or erase these records when conditions change.
Two new imaging studies and one bacterial-memory paper stand out for the concrete mechanisms they describe. |
