The Ecological Importance of Hummingbirds and the Risks of Artificial Food

Hummingbirds, belonging to the taxonomic family Trochilidae, are one of the most fascinating birds in the animal kingdom due to their unique morphology, characterized by a tiny size, a long, thin beak adapted for suction, and iridescent plumage that reflects light in dazzling metallic colors. Their presence in an ecosystem is an indicator of environmental health and they play a crucial role as specialized pollinators. Recently, the popularity of artificial drinkers with synthetic nectars has grown exponentially on social networks. However, specialized organizations such as PROMESA warn about the severe dangers of this practice. These food substitutes frequently contain dyes made from petrochemicals, substances that are potentially carcinogenic and harmful to the physiology of these birds, whose natural diet consists exclusively of flower nectar and small insects.

Botanical Strategy for a Safe Habitat

The ethical and sustainable solution to enjoy the visit of these birds lies in the recreation of a botanical garden designed specifically to satisfy their biological needs. This approach not only eliminates the risks associated with artificial feeders, but also contributes to the conservation of the species by providing natural habitat, authentic food sources and potential nesting sites. The selection of flora should prioritize species with tubular flowers, adapted to the shape of their beak, and with a high production of nectar rich in sucrose. Seasonal planning is essential to ensure constant resource availability from early spring to late summer.

Selection of Flora by Season and Type

The Pennsylvania Horticultural Society and other botanical institutions recommend a diversified selection of plants to ensure staggered flowering. For the early spring season, ideal species include the semi-evergreen vine Bignonia capreolata ‘Dragon Lady’, which produces orange-red flowers in early May, and Carolina Jessamine (Gelsemium sempervirens ‘Daisy’), a climber with abundant bright yellow flowers. The RedBuckeye tree (Aesculus pavia), with its deep red vertical clusters, and the Aquilegia canadensis, with its distinctive red petals and yellow center, complete the initial nutritional offering for migrating hummingbirds.

For summer, diversity should increase with mid- and late-flowering species. Bee balm (Monarda didyma ‘Jacob Cline’) is a fast-spreading plant with tubular red flowers that reach 4 to 5 feet tall, and is also deer resistant. The Cardinal Flower (Lobelia cardinalis) thrives in moist soil and saturates the garden with spikes of red flowers. Other options of high ecological value are Spigelia marilandica (Indian Pink), with its red flowers with curved yellow tips, and Butterfly milkweed (Asclepias tuberosa), which in addition to feeding hummingbirds serves as an essential host plant for monarch butterflies.

To structurally enrich the garden and offer shelter, shrubs and vines should be incorporated. Southern Honeysuckle (Diervilla sessilifolia) offers tubular yellow flowers, while Flame Azaleas (Rhododendron austrinum) bloom from May to June with fragrant orange and yellow flowers. The plum-leaved azalea (Rhododendron prunifolium), which blooms in late summer with orange and red flowers, ensures that the nectar supply is maintained until the end of the season.

Creating a hummingbird sanctuary through the use of native and appropriate flora is an act of active conservation. This method not only safeguards the health of these birds by avoiding harmful dyes in artificial nectars, but also strengthens local biodiversity by integrating pollinator plants into the ecosystem. A well-planned garden becomes a vital biological corridor, demonstrating that responsible observation of wildlife is possible and necessary.

Satellite Internet, the bet to close the digital divide in Mexico

Mexican geography limits fiber deployment, but low orbit satellites are emerging as an alternative.

Satellite internet as a solution to the digital divide in Mexico

Mountains, jungles and deserts make Mexico one of the countries with the most complex orography in Latin America. Bringing fiber optics to isolated communities implies an investment that is difficult to recover with few users. As a result, one in five households still lack internet access or receive poor service.

Faced with this scenario, low orbit (LEO) satellite internet is emerging as a strategic alternative. “Deploying physical infrastructure in Mexico is expensive due to geography. In many cases, satellite internet represents the most viable option to connect areas where fiber will not reach in the short term,” explains Ernesto Piedras, director of The CIU. Companies like Starlink, with more than 10,300 active satellites, already operate in the country. Since May 2021, it obtained a concession and closed 2024 with 160,631 subscriptions, making Mexico its second Latin American market, only behind Brazil. Starlink has signed contracts with CFE Telecomunicaciones for up to 1,556 million pesos to connect remote communities.

However, cost remains a barrier. While a fiber optic plan costs an average of 544 pesos per month, satellite internet starts at 899 pesos, plus equipment and installation. “Commercially it is still not as viable because it is still more expensive and requires purchasing an antenna whose price remains high,” says Fernando Esquivel, from The CIU. The service makes economic sense when it is shared between communities or companies, and with the support of public policies.

Experts agree that this technology will not replace fiber optics, but will complement it. “Terrestrial services are faster and have lower latency. Satellite communication reaches areas that fixed internet would not reach,” says Hugo Simg, from MediaTek. Deployment also requires regulation and coordination between governments and companies. The race to connect Mexico is no longer only being fought underground, but from space, where a new generation of satellites promises to reduce the digital divide that keeps millions out of the digital world.

Banks prepare for biometric facial controls in October

Banks claim to be ready for facial biometrics in branches since October.

| 1 min reading

The main banking institutions in the country claim to be prepared for the new regulations on facial biometric controls when opening accounts, which will come into force next October.

What did the banks declare?

Marcos Ramírez, general director of Grupo Financiero Banorte, pointed out that the institution has made progress to reinforce the identification and security of its users. “We are in time and form with everything established by law and a little ahead, with the prudential limits of the law,” he indicated.

These measures will strengthen control over customer identification. Since 2018, by regulation, fingerprint biometrics are already required to open accounts.

Implementation details

On July 1, the National Banking and Securities Commission (CNBV) incorporated facial biometrics into the regulation for multiple banking in customer identification and authentication. Institutions that opt ​​for this mechanism must comply with technical, operational and security requirements.

AI detects breast cancer with 90% accuracy

An autonomous model analyzes thermographs and classifies tissues without human intervention.

| 2 mins reading

An artificial intelligence model developed by Raúl Castro Ortega, a researcher at the Polytechnic University of Tulancingo, manages to identify breast cancer with an accuracy of 90%. The results were presented during the SPIE Photonics Europe 2026 International Congress, in Strasbourg, France.

How the system works

The system uses convolutional neural networks with attention mechanisms to analyze breast thermographs. Unlike traditional methods, the model autonomously learns the patterns of healthy and diseased tissue, without a specialist previously defining the characteristics of the images. This reduces processing time and improves consistency of results.

The study, titled “Breast thermography analysis using convolutional neural networks with attention mechanisms,” uses an algorithm based on the heat diffusion equation. This approach focuses analysis on thermogram regions of interest and classifies tissues with high levels of sensitivity and specificity.

Impact on early detection

The accuracy achieved represents a significant advance for the early detection of breast cancer, which can improve survival rates and facilitate timely treatment. The researcher highlighted that the system does not replace the specialist, but rather works as a support tool for faster and more consistent diagnoses.
