A Journey Into the Brain
Danielle Gerhard, PhD | Mar 22, 2024 | 10+ min read
With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Where the Wild Things Were

Conservationists are reintroducing large animals to areas they once roamed, providing ecologists with the chance to assess whether such “rewilding” efforts can restore lost ecosystems.
Adaptive Evolution
Alla Katsnelson | Aug 1, 2009 | 7 min read
By Alla Katsnelson Adaptive Evolution A once-rare type of clinical trial that violates one of the sacred tenets of trial design is taking off, but is it worth the risk? Doriano Solinas When researchers at Pfizer first began a Phase 2 trial of an acute stroke therapy in 2000, they decided to take a novel approach. The study—called the ASTIN trial—would determine the drug’s optimal dose not with three or four diffe

Large Scientific Collaborations Aim to Complete Human Genome
Brianna Chrisman and Jordan Eizenga | Sep 1, 2022 | 10+ min read
Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.
Scientists Meet at Rockefeller to Discuss Molecular Strategies in Biological Evolution
Ricki Lewis | Jul 19, 1998 | 6 min read
In science, things often aren't as simple as they seem. This is certainly the case for the genetic code. Even as elegant experiments in the 1960s assigned DNA and messenger RNA (mRNA) base triplets to specific amino acids, researchers were wondering if a protein's blueprints were the sole meaning imparted by those long strings of A, T, G and C. But back then, they could do little more than wonder. Today, with more than a dozen genomes sequenced, researchers can ask age-old questions as well as

Climate Change Helped Drive Homo sapiens’ Cousins Extinct: Study
Katarina Zimmer | Oct 15, 2020 | 6 min read
Sharp drops in global temperatures helped seal the fate of three extinct hominin species, including our close relatives, the Neanderthals, according to thousands of archaeological specimens and a model of past climate conditions.
