Luiz Fernando RibeiroBrachycephalus lulai on the tip of a pencil. Deep in the cloud-covered mountains of southern Brazil, researchers have identified a new species of pumpkin toadlet — a group of tiny, brightly colored frogs known for their bold hues. It’s been dubbed Brachycephalus lulai. According to a new study published in the journal PLOS One, this frog, which measures less than half an inch in length, is highly endemic and lives only in the leaf litter of a small section of the Serra do Quiriri mountain range. This is just the latest discovery to reveal how much of Brazil’s biodiversity remains hidden in plain sight — and why conservationists are so keen to protect the region. A Frog So Small It Fits On A Pencil Tip Researchers have been attempting to catalog all of Brazil’s Brachycephalus species for several years now, but that task is easier said than done. Despite their vivid orange shade — a warning to predators — these tiny frogs are incredibly difficult to spot among the leaf litter. So, how did scientists find B. lulai? By listening. Males of the species make unique mating croaks, which helped lead researchers directly to them. Luiz Fernando RibeiroB. lulai lives in one of Earth’s most threatened ecosystems. After collecting the specimens, researchers analyzed them in a lab, studying their features and conducting genetic sequencing. They concluded that they had indeed discovered a new species, which they named Brachycephalus lulai, after Brazilian president Luiz Inácio Lula da Silva. “Through this tribute,” the scientists wrote in their paper, “we seek to encourage the expansion of conservation initiatives focused on the Atlantic rainforest as a whole, and on Brazil’s highly endemic miniaturized frogs in particular.” Indeed, this discovery is sparking conversations about conservation in the South American country. The Importance Of The Discovery Of ‘B. Lulai’ While B. lulai was classified as being of “least concern” from a conservation standpoint, other frogs in the same region are endangered, which has ignited debate about how to protect the creatures from habitat loss. Brazil’s Atlantic Forest, where B. lulai was found, is one of the most threatened biomes on the planet. Centuries of deforestation, agriculture, and urban expansion have reduced it to a fraction of its original size, leaving many species isolated in small, fragmented pockets of habitat. Every new discovery in this region serves as a reminder of how much could be lost before it’s ever even documented. Tiny amphibians like pumpkin toadlets are especially vulnerable. Their survival depends on stable microhabitats — moist leaf litter, intact forest floors, and clean water sources — all of which are disrupted by even minor environmental changes.

Because they are so sensitive to temperature, humidity, and pollution, amphibians often serve as early warning indicators of ecological decline. The presence of a previously unknown species suggests that these forests are full of biological discoveries, but it also raises concerns about how many undiscovered species may already be on the brink. Pumpkin toadlets in particular are known for their unusual evolutionary traits, from their bright coloration to their reduced hearing abilities and bioluminescent bones. Each new species adds another piece to the puzzle of how these frogs evolved such unique characteristics — and how they continue to adapt to their environment. Understanding these evolutionary pathways can help researchers trace how species respond to environmental stressors, which is increasingly important in an ever-warming world. Documenting new species also strengthens the case for conservation. When scientists can point to unique, endemic animals found nowhere else on Earth, it becomes harder for policymakers to ignore the ecological value of these forests. A single tiny frog may not seem like much, but discoveries like this one help build the scientific and public momentum needed to protect the last remnants of Brazil’s Atlantic Forest.

Turkish Ministry of Culture and TourismThe fresco of Jesus as the “Good Shepherd” that was recently discovered in Turkey. Amid ongoing excavations at the Hisardere Necropolis in the Turkish district of Iznik — known in antiquity as Nicaea — archaeologists have uncovered an early Christian fresco depicting the “Good Shepherd Jesus,” a rarely-seen figure that could very well be the only example of its kind in the region. No artifacts were recovered nearby that could help experts date the fresco, but the tomb in which it was found is believed to date to the third century C.E. At that time, the region was under Rome’s control, thus Christians were facing widespread persecution because the religion had not yet been legalized throughout the empire. However, a not-explicitly-Christian image like the “Good Shepherd” would have allowed believers to express their faith without fear. The Rare “Good Shepherd” Fresco Discovered Inside An Underground Tomb In Turkey The fresco adorns the north wall of a hypogeum — an underground chamber tomb — that has been exceptionally well preserved for well over a millennium. Although its southern wall has been heavily damaged over the years, the ceiling, as well as the east, west, and north walls remain in near-perfect condition, offering archaeologists a unique opportunity to study the fresco in situ. The walls and ceiling are adorned with decorative bird and plant motifs, as well as portraits of noble men and women with their enslaved attendants. Directly behind the kline — a square, terracotta funerary bed — is the fresco, a common form of visual art throughout the Mediterranean during the early years of Christianity. It depicts Jesus with distinctly Roman attributes, youthful and clean-shaven, wearing a toga and carrying a goat across his shoulders. This specific type of figure, however, is almost never found in Anatolia. And of the few examples found in the region, the one from Hisardere is the best preserved. Turkish Ministry of Culture and TourismArchaeologists uncovered the fresco in August 2025. Jesus as the Good Shepherd was an early expression of faith before the cross was widely adopted as the symbol of Christianity, along with a revised image of a bearded, older, robed Jesus. This image became the standard not long after Rome legalized Christianity in 313 C.E. But while Christianity was still outlawed, the Good Shepherd was an important symbol of protection, salvation, and divine guidance for early Christians. As lead archaeologist Gulsen Kutbay told the Associated Press, however, this newly-found fresco is possibly the “only example of its kind in Anatolia.” The symbol’s presence in this tomb evokes a fascinating period in history where Christianity was practiced discreetly due to fear of persecution. Iznik Museum archaeologist Eren Erten Ertem said the fresco shows “a transition from late paganism to early Christianity, depicting the deceased being sent off to the afterlife in a positive and fitting manner.” Furthermore, this is the first time a depiction of Jesus has been identified in a tomb at the Hisardere Necropolis, which opens further paths for investigating early Christian artwork in Anatolia. Why Nicaea Was An Important Site In Early Christianity Turkish Ministry of Culture and TourismOther motifs featured in the tomb’s frescoes included birds, flowers, and goats. Amazingly, this discovery was made just one week after Pope Leo XIV visited Iznik to commemorate the 1,700-year anniversary of the Council of Nicaea in 325 C.E. The First Council of Nicaea convened under Roman Emperor Constantine I, marking Christianity’s transition from a religion whose followers faced persecution to one that now had imperial favor. Approximately 300 bishops gathered to address the Arian controversy, which questioned Christ’s divine nature. So it was that the council produced the Nicene Creed, affirming that Jesus was “of one substance” with God the Father — a theological statement still upheld in many Christian churches around the world to this day. Meanwhile, the council also established the timing of Easter and created frameworks for church governance.

The Second Council of Nicaea in 787 C.E. tackled the iconoclasm controversy, which had divided the Byzantine Empire for decades. Church leaders ultimately endorsed the veneration of religious icons, distinguishing between worship due to God alone and the respect shown to a sacred image — a decision which heavily influenced Christian art and worship practices, particularly in Eastern Orthodoxy. Nicaea’s strategic location in northwestern Asia Minor made it accessible to bishops traveling from across the Christian world, from Spain to Mesopotamia. The city’s walls and imperial patronage provided security for these contentious theological debates. The councils’ decisions unified Christian doctrine during formative centuries, establishing precedents for how the church would resolve disputes and define orthodoxy. The Nicene Creed remains Christianity’s most widely accepted statement of faith, transcending denominational boundaries among Catholics, Orthodox, and most Protestant traditions. The newly discovered fresco serves as a reminder of Iznik’s important place in the course of Christian history.
