Hace 400 milenios, en Israel….

Resulta que han encontrado dientes “humanos, demasiado humanos” de hace 400.000 años, en un yacimiento israelita, cerca de Tel Aviv. Esto en sí no significa nada. Pero sí en relación con todo lo que hasta ahora se ha ido sabiendo sobre nuestros lejanos ancestros y nuestra evolución, para lo que …

Introduction

Stepping Away From the Trees For a Look at the Forest

by Science News Staff

Science's news staff takes a break from reporting to review some big ideas of the past 10 years and the technologies that made them possible.

The Dark Genome

Since the publication of the human genome sequence in 2001, scientists have found that the so-called junk DNA that lies between genes actually carries out many important functions.

Precision Cosmology

In the past decade, cosmologists have deduced a very precise recipe for the content of the universe, as well as instructions for putting it together, transforming cosmology from a largely qualitative endeavor to a precision science with a standard theory.

Ancient DNA

Scientists have been giving us new views of the prehistoric world in the past decade that hinge on the realization that "biomolecules" such as ancient DNA and collagen can survive for tens of thousands of years and give important information about long-dead plants, animals, and humans.

Water on Mars

The past decade's half-dozen martian missions have made it clear that early in Mars history, liquid water on or just inside the planet did indeed persist long enough to alter rock and, possibly, sustain the origin of life.

Reprogramming Cells

By prompting a cell to overexpress a few genes, researchers have discovered in the past decade how to turn a skin or blood cell into a pluripotent cell: one that has regained the potential to become any number of cells in the body.

The Microbiome

This past decade has seen a shift in how we see the microbes and viruses in and on our bodies, most of which are commensal and just call the human body home; collectively, they have come to be called the human microbiome.

Exoplanets

Data on the 500-and-counting planets discovered outside of our solar system in the past decade are revolutionizing researchers' understanding of how planetary systems form and evolve.

Inflammation

Over the past decade, it has become widely accepted that inflammation is a driving force behind chronic diseases that will kill nearly all of us: cancer, diabetes and obesity, Alzheimer's disease, and atherosclerosis.

Metamaterials

In the past decade, physicists and engineers pioneered new ways to guide and manipulate light, creating lenses that defy the fundamental limit on the resolution of an ordinary lens and even constructing "cloaks" that make an object invisible-sort of.

Climate Change Research

In the past few years, climate scientists finally agreed that the world is indeed warming, humans are behind it, and natural processes are unlikely to rein it in-just as they had suspected.
