Iwas never into house plants until I bought one on a whim—a prayer plant, it was called, a lush, leafy thing with painterly green spots and ribs of bright red veins. The night I brought it home I heard a rustling in my room. Had something scurried? A mouse? Three jumpy nights passed before I realized what was happening: The plant was moving. During the day, its leaves would splay flat, sunbathing, but at night they’d clamber over one another to stand at attention, their stems steadily rising as the leaves turned vertical, like hands in prayer.

“Who knew plants do stuff?” I marveled. Suddenly plants seemed more interesting. When the pandemic hit, I brought more of them home, just to add some life to the place, and then there were more, and more still, until the ratio of plants to household surfaces bordered on deranged. Bushwhacking through my apartment, I worried whether the plants were getting enough water, or too much water, or the right kind of light—or, in the case of a giant carnivorous pitcher plant hanging from the ceiling, whether I was leaving enough fish food in its traps. But what never occurred to me, not even once, was to wonder what the plants were thinking.

To understand how human minds work, he started with plants.

Robots are all around us, from drones filming videos in the sky to serving food in restaurants and diffusing bombs in emergencies. Slowly but surely, robots are improving the quality of human life by augmenting our abilities, freeing up time, and enhancing our personal safety and well-being. While existing robots are becoming more proficient with simple tasks, handling more complex requests will require more development in both mobility and intelligence.

Columbia Engineering and Toyota Research Institute computer scientists are delving into psychology, physics, and geometry to create algorithms so that robots can adapt to their surroundings and learn how to do things independently. This work is vital to enabling robots to address new challenges stemming from an aging society and provide better support, especially for seniors and people with disabilities.

From burgers to sausages and steak tips to chicken nuggets, there’s no shortage of plant-based “meat” products on grocery store shelves and in restaurants these days. Companies like Beyond Meat and Impossible Foods have done an impressive job diversifying their offerings, with almost any processed meat you can think of now on their lists (even beef jerky and popcorn chicken). But a key cut of meat is still missing from these big names’ menus: a good old-fashioned filet, just like the cows make ‘em.

I served the steak with quinoa and sauteed veggies, and after a few bites, I couldn’t deny it was both tasty and had a pleasant texture. Did it taste or feel like a real steak? Not really. The real meat it most reminded me of was rib meat, the kind that easily pulls off the bone when the ribs have been slow-cooked; soft and tender, but not dried out. The plant-based steak had a distinctly fatty-like mouthfeel without the excessive oiliness you sometimes get from animal fat.

A new study has shown that bumblebees pick up new “trends” in their behavior by watching and learning from other bees, and that one form of a behavior can spread rapidly through a colony even when a different version gets discovered.

The research, led by Queen Mary University of London and published in PLOS Biology, provides strong evidence that social learning drives the spread of bumblebee behavior—in this case, precisely how they forage for food.

“The host star, TOI-5205, is just about four times the size of Jupiter, yet it has somehow managed to form a Jupiter-sized planet, which is quite surprising!” exclaimed Dr. Shubham Kanodia, who is a postdoctoral fellow in the Carnegie Earth & Planets Lab and an expert in red dwarf stars, and lead author of the study. Dr. Shubham recently discussed the discovery in an in-depth blog post, as well. Using food as an analogy, Jupiter orbiting our Sun is equivalent to a pea orbiting a grapefruit, whereas TOI-5205b orbiting its parent star would be equivalent to a pea orbiting a lemon.

The general theory of planetary formation begins with a massive, rotating disk of gas and dust encircling young stars, with gas planets initially being formed from rocky material comprising approximately 10 Earth masses. Over time, this material forms the core of the giant planet, which then accumulates large amounts of gas from the disk to produce the massive gas giants we observe today. As it turns out, the confirmation of TOI-5205b could throw this theory into disarray.

What will people be eating at the end of the 21st century?

The foods we eat are determined by cultural roots, geography, and moral and ethical concerns. Omnivore, vegetarian, and vegan are choices.

Rodents are considered one of the animal pests with the greatest impact on agricultural production and public health, especially the brown or Norway rat (Rattus norvegicus), the black or roof rat (Rattus rattus) and the house mouse (Mus musculus). Its control is an increasing problem worldwide. The intensification of agricultural production methods as well as the increase in merchandise transport to sustain growing populations is leading to an increase in waste production causing the growth of these rodent populations. The estimated losses in crop production caused by rodents range from between 5% and 90% (Stenseth et al., 2003) and this can cause problems in food security during harvesting (Belmain et al., 2015). Other negative impacts result from some rodent species living very close to human environments that can have a direct influence not only on human health through potential transmission of gastroenteric diseases and zoonosis to householders but also on domestic livestock. Therefore, rodent pest control is crucial and nowadays, the only effective control method available is the use of anticoagulant rodenticides (ARs).

ARs are so named because they interfere with the blood coagulation processes. The processes of activating various coagulation factors depends on the amount of vitamin K in its reduced form that exists in the organism. ARs inhibit the enzyme vitamin K 2,3-epoxide reductase (VKORC1) that is responsible for reducing vitamin K and maintaining the balance between its oxidized and reduced forms. The inhibition of VKORC1 prevents the activation of the coagulation factors resulting in animal death by internal bleeding. However, the intensive use of ARs can cause rodents to lose their susceptibility and become resistant to them. Genetic resistances to ARs are mainly associated with mutations or single nucleotide polymorphisms (SNPs) in the gene that codes for VKORC1 (vkorc1), causing amino acid substitutions in the VKORC1 protein ( Pelz et al., 2005 ). There are studies on this topic in several countries of central and northern Europe detecting rodent populations resistant to AR. Currently, there are at least 13 mutations mainly located in the exon 3 of the vkorc1 gene described in various countries of the European Union that confer resistance to specific ARs ( Berny et al., 2014 ; Goulois et al., 2017 ). In Eastern and Southern European countries, the information on the incidence of resistances to rodenticides is scarce, and it is becoming increasingly important to generate information on this subject ( Berny et al., 2014). In Spain, a mice population at the coastal countryside showing an adaptive introgression between house mouse and Algerian mouse that confers anticoagulant resistance has been described ( Song et al., 2011 ). While recently, four VKORC1 mutations in black rat were found in Toledo, Segovia and Zaragoza ( Goulois et al., 2016 ; Damin-Pernik et al., 2022 ). Any increase in resistant in rodent populations would lead to pest control issues that may causing serious agricultural, farming and public health problems.

Scientific advances have revolutionized the study of anticoagulant resistances in terms of understanding their genetic basis, physiological mechanisms and geographical distribution. The techniques based on the extraction and partial sequencing of genomic DNA allow a fast and precise monitoring of possible genetic resistances. Most of these tests involve laboratory studies using live rodents or blood samples taken from animals in the field. However, the improvement of DNA extraction techniques now allows the analysis of faecal samples (stool), increasing the number of samples that can be taken without the need for sampling by trapping or the management of dead animals (Meerburg et al., 2014). The importance of initial detection of genetic resistances due to mutations is crucial. The hypothesis of work, presenting it as a null hypothesis, is that there will be no rodent mutations in the vkorc1 gene in Spain.

Psyllium fiber protects against ulcerative colitis and suppresses inflammation by activating the bile acid nuclear receptor, a mechanism that was previously unrecognized, according to a new study by researchers in the Institute for Biomedical Sciences at Georgia State University.

The findings published in the journal Cellular and Molecular Gastroenterology and Hepatology (CMGH) reveal that psyllium, which is semi-soluble and derived from Plantago seeds, inhibits inflammation that can lead to colitis in mice by increasing serum bile acids, resulting in the activation of the farnesoid X receptor (FXR), a bile acid nuclear receptor.

Fiber-rich foods promote intestinal and metabolic health, but the extent of protection varies for each fiber type and the mechanisms that offer this protection are poorly defined. It has been unclear whether dietary fiber can benefit severe forms of intestinal inflammation, such as Crohn’s disease and ulcerative colitis, which are collectively known as inflammatory bowel disease (IBD) and affect 3 million adults in the United States.

Whether it is steamed idli, Gujarati snack, panki; Parsi’s patra ni machchi, Assam’s bhapot diya maach or the elaborate Onam Sandhya from Kerala, the humble banana leaf has found its way into many cuisines.

It is also very versatile as food can be steamed, grilled and deep-fried. It can also be used as a serving plate and packaging material.

While banana leaves have been an integral part of the desi food and traditions, did you know there are health benefits to it as well?
