A New Wild Cat Species Has Been Formally Identified in Bolivia for the First Time in More Than 100 Years.

Scientists have formally described a new tiny wild cat species from Bolivia’s Yungas cloud forests: the Tilcayo tiger cat (Leopardus tilcayo). 🐈🌿 The discovery began when a local man found a kitten near a forest road in 2016 and took it home, thinking it was a domestic cat. DNA analysis later showed that it was a distinct species whose lineage separated from other tiger cats around 1.4 million years ago. The cat weighs around 1.4 kg (3 lb), and scientists still don't know how many live in the wild. Source: Curre

Post Menopausal Ovaries May Not Be “switched Off” After All, New Research

Post Menopausal Ovaries May Not Be “switched Off” After All, New Research

Recent research suggests that ovaries may remain biologically active after menopause rather than simply becoming inactive. A mouse study found increased immune activity and tissue changes in post-reproductive ovaries, while a preliminary human study found ongoing changes in proteins related to inflammation, immune responses and tissue remodelling. However, the first study was conducted in mice and the human research is still a preprint, so the health significance of these changes remains uncertain.

Nearly 73% of All U.S. TV Viewing Remains Ad-Supported, and Streaming Is Taking Over the Sharetitled Draft

Nearly 73% of All U.S. TV Viewing Remains Ad-Supported, and Streaming Is Taking Over the Sharetitled Draft

Nielsen’s Q1 2026 data shows that advertising remains a major part of U.S. television viewing, with nearly 73% of TV viewing taking place on ad-supported services. Streaming accounted for 46.6% of ad-supported viewing, while broadcast represented 28.2% and cable 25.2%. Despite the rapid growth of streaming, the overall share of ad-supported TV viewing was almost unchanged from 72.4% in Q1 2025, suggesting that streaming is changing where viewers see ads rather than eliminating ad-supported television.

Europe Needs €584 Billion Just To Upgrade Its Electricity Grids

Europe needs massive investment in its electricity grids because electricity demand and renewable energy generation are both increasing while much of the existing grid is aging. Around €584 billion was estimated to be needed between 2020 and 2030 for electricity infrastructure. Expanding and modernising grids is essential to connect new renewable projects, support businesses and industries, and move electricity efficiently across Europe.

6 Ways to Rewire Your Brain: Backed by Science

Your brain is not fixed; it continues to adapt throughout life. Focus, mistakes, sleep, novelty, exercise and repetition can all support neuroplasticity, helping your brain strengthen and reorganise neural connections. The key message: what you repeatedly learn, practise and experience can shape your brain over time.

Menopause May Change Almost Every System in the Body, Study of 300 Million Lab Tests Suggests

An analysis of 300 million lab tests from over 1 million women suggests menopause may affect many body systems, not just reproductive hormones. Changes were observed in areas including bone, liver, cholesterol, kidney, muscle, blood cells, inflammation, and metabolism, with some changes beginning years before the final menstrual period. However, the study is a preprint based on existing medical records, so it cannot prove cause and effect. Further research and peer review are needed to confirm the findings.

As of 2026, HIV Can Be Treated So Effectively That It Cannot Be Sexually Transmitted

Modern antiretroviral therapy (ART) can suppress HIV to undetectable levels, allowing people with HIV to live healthy lives. Under the principle U=U (Undetectable = Untransmittable), people who maintain an undetectable viral load do not sexually transmit HIV. However, ART does not cure HIV, so treatment must be continued to maintain viral suppression.

A Wild Horse Returns: Przewalski’s Horse Foal Born in Kazakhstan After 200 Years

A male Przewalski’s horse was born in Kazakhstan on August 22, 2026: the first in the country in more than 200 years. The birth marks an important milestone in the species’ reintroduction, which began in 2024 after it disappeared from the wild in the 1960s. Conservationists hope the new generation will help establish a self-sustaining population and restore local ecosystems.

Dark Chocolate Is More Than Just an Antioxidant: Cocoa Flavanols Modestly Improve Blood Pressure and Endothelial Function in Clinical Trials

Research suggests that cocoa flavan-3-ols, particularly epicatechin, may benefit cardiovascular health by improving endothelial function and supporting nitric oxide signalling, which helps blood vessels relax and widen. A 2019 review found a modest improvement in flow-mediated dilation, while a larger 2025 meta-analysis of 145 trials involving 5,205 participants reported improved endothelial function and a small reduction in blood pressure.

Honeybee Venom and Melittin Rapidly Kill Up To 100% of Aggressive Breast Cancer Cells in Laboratory Study

A 2020 lab study found that honeybee venom and its main component, melittin, rapidly killed breast-cancer cells including aggressive triple-negative and HER2-positive cells. In laboratory experiments, cancer-cell membranes were destroyed within about 60 minutes. However, this was preclinical research (cells/lab experiments), not a proven treatment in humans. Bee venom can also be dangerous, so it should not be used as a cancer treatment outside clinical research.
