Jurassic Journeys: Mary Anning’s impact on evolutionary science
Mary Anning made some of the most significant geological discoveries in history, but her life and work have largely gone unnoticed due to the gender discrimination prevailing in 19th-century England. She meticulously explored the beaches of Dorset on the southwest coast of England, uncovering evidence of marine reptiles that shook the existing scientific knowledge.
Anning’s fossils are believed to have greatly influenced Charles Darwin’s theory of evolution. However, being a poor and uneducated woman, she was never taken seriously by English society. The area where Mary conducted her research is now known as the Jurassic Coast, a stretch of about 152 kilometers in Dorset and Devon counties, recognized by UNESCO for its exceptional rocks, fossils, and geographical features.
Her Great Discoveries
Venturing along the cliffs of Lyme Regis, Mary observed every detail of the rocks, patiently searching through the strata. In 1811, she was informed by Joseph about a peculiar fossilized skull he had found. Mary meticulously excavated the skeleton for months, revealing a 5.2-meter-long creature.
Locals speculated that the boys had found a monster, while the scientific community thought it might be a crocodile. This discovery coincided with Georges Cuvier formulating his “Essay on the Theory of the Earth,” challenging religious principles by proposing catastrophic events in Earth’s history causing extinctions.
The mysterious specimen found by the Annings was eventually called Ichthyosaur, or “fish lizard,” a marine reptile that lived about 200 million years ago. Mary’s controversial and exceptional discoveries continued, including the first complete skeleton of a plesiosaur in 1823, challenging skeptics who initially thought it was fake.
Mary also found the first pterosaur outside Germany, and she is credited as a pioneer in the study of coprolites, fossilized feces. Despite her exceptional achievements, Mary faced systematic discrimination due to her gender, excluded from academic institutions. She persevered, self-educated, and established connections with scientists who recognized her worth.
Mary Anning was never formally admitted to the Geological Society of London due to her gender. The institution acknowledged her talent and contributions many years after her death from breast cancer in 1847 at the age of 47. Mary undoubtedly pioneered in a male-dominated world, paving the way for future generations of female scientists.

Argentina detects first local cases of Influenza A (H3N2) Subclade K
Argentina’s National Administration of Laboratories and Health Institutes (ANLIS) “Dr. Carlos G. Malbrán” has confirmed the detection of three cases of influenza A (H3N2) corresponding to subclade K in the country. These are the first locally recorded cases of this variant, which has become predominant in several countries in the Northern Hemisphere in recent months and is associated with higher transmissibility.
The cases were identified through the National Network of Laboratories and Sentinel Units and confirmed by the National Reference Laboratory of INEI-ANLIS using genomic sequencing techniques. According to health authorities, the cases involve two adolescents from the province of Santa Cruz, detected as part of the Ambulatory Monitoring Strategy for Acute Respiratory Infections, and a child who had been hospitalized in the Autonomous City of Buenos Aires.
In all three cases, patients experienced mild illness and recovered without complications. Officials did not specify whether any of the affected individuals had a recent travel history.
The jurisdictions involved have already launched the corresponding epidemiological investigations and are responsible for ensuring timely medical care for the detected cases. According to the latest integrated surveillance report, the circulation of influenza and other respiratory viruses in Argentina remains within expected levels for this time of year.

Pentagon confirms Trump pick for SouthCom as U.S. military pressure grows
Former U.S. President Donald Trump has nominated a Marine Corps lieutenant general to lead U.S. Southern Command (SouthCom), the Pentagon announced on Friday, as Trump said he does not rule out the possibility of a war with Venezuela.
If confirmed by the U.S. Senate, Marine Corps Lieutenant General Francis L. Donovan would replace an admiral who, according to media reports, criticized recent attacks on vessels allegedly linked to drug trafficking off the Venezuelan coast.
Washington has deployed a significant military presence in both the Caribbean and the Pacific, where it has carried out airstrikes against boats it claims were used by suspected drug traffickers. According to an AFP tally based on official information, the attacks have left more than 100 people dead.
The Venezuelan government has denounced what it describes as a plot to overthrow President Nicolás Maduro and seize the country’s oil resources.
In a statement published Friday on the Pentagon’s website, U.S. Secretary of Defense Pete Hegseth announced that Trump had nominated Lieutenant General Donovan to serve as commander of U.S. Southern Command.
SouthCom is responsible for U.S. military operations in Central and South America, as well as parts of the Caribbean.
According to the Department of Defense, Donovan currently serves as deputy commander of U.S. Special Operations Command. His appointment is subject to Senate confirmation.

Trump moves to reclassify marijuana as less dangerous substance
Former U.S. President Donald Trump signed an executive order on Thursday to reclassify marijuana as a less dangerous addictive substance, a move aimed at encouraging medical research without immediately opening the door to federal-level decriminalization.
Trump said that “people were begging” him to make the decision, particularly individuals suffering from chronic pain. He stressed, however, that the measure “is not at all a decriminalization” of marijuana for non-medical use.
“I’ve always told my children: don’t use drugs, don’t drink, don’t smoke,” Trump added. He is a well-known teetotaler.
A senior government official described the decision as “common sense” during a briefing with reporters, noting that marijuana and CBD-based products — a compound derived from cannabis known for its relaxing properties — are already widely used in the United States by patients dealing with chronic pain.
Most U.S. states currently allow the use of cannabis for medical purposes, and more than 20 states, along with the nation’s capital, Washington, D.C., have also legalized recreational use.
