Scientists observe nanosize microtubules 'treadmilling' across plant cells
A study in the journal Science is offering new insights into a long-standing mystery about plant growth. (2003-04-24)
The mechanics of anti-tumor activity outlined
Inhibiting the growth and the angiogenic properties of cancer is an important modality for cancer treatment and research. (2003-04-22)
Optical trap provides new insights into motor molecules - nature`s ultimate nanomachines
When it comes to nanotechnology, many researchers turn to nature for inspiration. (2003-02-25)
Synthesized molecule holds promise as antitumor agent
Amphidinolides, a family of natural compounds that have shown promise as powerful antitumor agents, pose problems for cancer researchers because they are found in only minute amounts, and only in microscopic marine flatworms that live off the coasts of Japan and the U.S. (2003-02-06)
Study finds new target for development of anti-cancer drugs
Penn State College of Medicine researchers have identified a new target for anti-cancer therapeutics -- km23/mLC7-1, a protein that helps to direct protein traffic in the cell. (2002-09-04)
New study of coated stent - long-term results disappointing
A new drug-eluting stent - a tiny spring device coated with medicine that keeps blood vessels from reblocking after angioplasty - may have a problem holding up over time, say researchers in today's rapid access publication of Circulation: Journal of the American Heart Association. (2002-04-01)
Supercomputer paints electric landscape of cellular structures
Researchers at the University of California, San Diego have mapped key cellular structures using a new method to harness the power of supercomputing. (2001-08-20)
Better computer modeling provides a new look at large biomolecules
A new computational method for studying the electrical landscape of large biological molecules may enable HHMI researchers to make a leap from modeling molecules of 50,000 atoms to those of more than a million atoms. (2001-08-20)
Walking proteins need to rock and roll, new study finds
The living cell has been compared to a train station at rush hour, but unlike a congested city commute, cellular traffic is efficient, thanks in part to the protein kinesin - a motor molecule that hauls chromosomes and other vital cargo on microtubule tracks. (2001-06-27)
Viruses concentrate
Many reproducing viruses need to concentrate all of their components in one area of the cell, called a viral factory, so that all of their parts are present in sufficient quantities to allow assembly. (2001-04-30)
How the cell finds its center
Yeast cells place their nucleus in the center of the cell, where the nucleus helps define where the cell will later divide in half. (2001-04-16)
New sub-cellular structure discovered
A group of scientists from Iowa State University doing research under a National Science Foundation (NSF) grant reports that they have discovered a new and different spindle structure during cell division that could lead to better insight into how abnormal cells divide, as in forms of cancer. (2000-12-26)
Human reproductive success tied to mitochondrial organization in eggs
The viability of a developing human embryo appears to be related to the clustering and subsequent symmetrical distribution of tiny DNA structures in the egg's fluid surrounding its nucleus prior to the first cell division, according to a new Colorado study. (2000-12-19)
Building bulkier smooth muscle cells through endoreduplication
In normal aging, unusually large smooth muscle cells accumulate in the walls of the aorta. (2000-10-10)
Review article highlights tiny motors driving cell division
In this week's issue of the journal Nature, a UC Davis research group studying the intricacies of cell division provides an overview of the current science. (2000-09-05)
Single amino acid mutation dramatically alters direction of a molecular 'motor'
Researchers from Duke University Medical Center and Tohoku University, Japan, report finding two single amino acid mutations that disrupt the sense of direction in a molecular 'motor,' and creating one for the first time that is equally likely to travel either up or down its track. (2000-08-22)
New horizons, treatments in anticancer chemistry
With the help of chemistry, researchers are continuing their quest to keep cancer in check. (2000-03-26)
Learning how cell's tiny motor powers its mobility
HHMI researchers have for the first time shown how the world's smallest moving machines generate the motion needed to transport their chemical cargo throughout cells. (1999-12-15)
Tau Gene Linked To Family Of Neurodegenerative Disorders; Finding May Yield Insight Into Onset Of Alzheimer's Disease
Researchers led by a UC San Francisco neurologist are reporting findings that they say may put them an important step closer to understanding the way in which Alzheimer's disease ravages the brain cells of patients. (1998-10-27)

Our Relationship With Water
We need water to live. But with rising seas and so many lacking clean water – water is in crisis and so are we. This hour, TED speakers explore ideas around restoring our relationship with water. Guests on the show include legal scholar Kelsey Leonard, artist LaToya Ruby Frazier, and community organizer Colette Pichon Battle.

#569 Facing Fear
What do you fear? I mean really fear? Well, ok, maybe right now that's tough. We're living in a new age and definition of fear. But what do we do about it? Eva Holland has faced her fears, including trauma and phobia. She lived to tell the tale and write a book: "Nerve: Adventures in the Science of Fear".

First things first: our very own Latif Nasser has an exciting new show on Netflix. He talks to Jad about the hidden forces of the world that connect us all. Then, with an eye on the upcoming election, we take a look back: at two pieces from More Perfect Season 3 about Constitutional amendments that determine who gets to vote. Former Radiolab producer Julia Longoria takes us to Washington, D.C. The capital is at the heart of our democracy, but it's not a state, and it wasn't until the 23rd Amendment that its people got the right to vote for president. But that still left DC without full representation in Congress; D.C. sends a "non-voting delegate" to the House. Julia profiles that delegate, Congresswoman Eleanor Holmes Norton, and her unique approach to fighting for power in a virtually powerless role. Second, Radiolab producer Sarah Qari looks at a current fight to lower the US voting age to 16 that harkens back to the fight for the 26th Amendment in the 1960s. Eighteen-year-olds at the time argued that if they were old enough to be drafted to fight in the War, they were old enough to have a voice in our democracy. But what about today, when even younger Americans are finding themselves at the center of national political debates? Does it mean we should lower the voting age even further? This episode was reported and produced by Julia Longoria and Sarah Qari. Check out Latif Nasser's new Netflix show Connected here. Support Radiolab today at
