Life & Biology
From the genetic code to entire ecosystems, this section delves into the science of living things.
AI genome decoding ethical guidelines needed for engineered life.
Biology has transitioned from a descriptive science to a generative one, meaning scientists can now create entirely new species rather than just cataloging existing ones, according to The Guardian .
Top 4 Longest Living Animal Species & Their Health Secrets
While human fertility often begins its decline in our 30s, some birds and reptiles maintain full reproductive capacity throughout their entire, exceptionally long lives.
What Are Major Evolutionary Transitions and How Do They Occur?
Imagine a cosmic clock where the ticks mark major evolutionary leaps.
Assembly Theory, Explained: The Physics-of-Life Framework That Has Scientists Arguing Over Words
Assembly Theory, a new framework by Sara Walker and Leroy Cronin, proposes an "assembly index" to quantify object complexity and detect life, aiming to bridge physics and biology. The theory has ignited debate over its broad definitions and ambitious claims regarding the origin of life and evolution.
How Deep-Sea Life Survives the Crushing Dark—and Why Its Biology Matters to Medicine
Deep-sea life survives extreme conditions through physical and molecular adaptations, including specialized protein folding mechanisms that have evolved convergently. This unique biology holds potential for biomedical innovation, inspiring research into new drug discoveries.
Superbug Spread Resistance Threatens Global Health
In Croatia, 90% of Acinetobacter baumannii strains were resistant to multiple antibiotics by 2018, signaling a global collapse in treatment efficacy for this deadly superbug.
How Do Organisms Adapt to Environments Without Oxygen?
In the deepest oceans or even within our own bodies, environments exist where oxygen is completely absent.
Why "Designer Babies" Divide Us: Heritability, Not the Technology Itself
The controversy surrounding "designer babies" stems from two key questions: whether genetic changes will be passed to future generations and if they aim to treat disease or select for desired traits, rather than the editing technology itself.
Denis Noble's Case Against the Gene-Centric View of Evolution, Explained
Denis Noble challenges the traditional gene-centric view of evolution, arguing that genes are not sole controllers but part of complex, interactive networks. He proposes a systems biology, organism-centric alternative where genes, cells, and environments interact reciprocally.
What is Epigenetics and How Do Environment Factors Affect Gene Expression?
A sweeping meta-analysis, synthesizing 140 studies and 65,919 participants, reveals a profound truth: social determinants of health are deeply linked to changes in our 'epigenetic clocks.
What is the Extended Evolutionary Synthesis?
In 2014, a prominent article in Nature directly posed the question: 'Does evolutionary theory need a rethink?
What Synthetic Life Is—and Why Its "Design-and-Print" Approach Matters for Our Future
Synthetic biology engineers life by writing DNA from scratch, moving beyond traditional genetic modification to a "design-and-print" approach. This transformative field holds immense potential for industry and medicine but also raises significant safety, ethical, and philosophical questions about the definition of life.
