How Bacteria Make a Grappling Hook for Propulsion

Many bacteria, including important pathogens, move by projecting grappling-hook-like extensions called type IV pili from their cell bodies. After these pili attach to other cells or objects in their environment, the bacteria retract the pili to pull themselves forward.

  • Teeth Reveal the Secrets of Human Evolution in Latest Research

    New research led by scientists at Monash University has shown how by studying teeth of our ancestors can reveal some of the secrets of human evolution.

  • What Bats Might Reveal About Your Brain

    Researchers think a bat's brain might give us clues on how human brains are able to decide on which particular sounds are deserving of their attention.

  • The World of Chocolate

    Students at Johns Hopkins University are getting a close up look at chocolate to better understand materials science.

  • A Closer Look at the Molecule That Gives Skin Elasticity

    Through Tropoelastin's movements, it assembles to make elastic fibers, tubes and sheets for tissue repair. It is used to make and fix many different elastic tissues in the body. This material relates to the paper titled, 'Subtle balance of tropoelastin molecular shape and flexibility regulates dynamics and hierarchical assembly. [Weiss Lab, University of Sydney]

  • How Humans Might Survive Climate Change

    Paleoanthropologist Dr. Matthew Skinner predicts how the human body will evolve in future habitat scenarios.

  • 5,300-Year-Old Ötzi the Iceman’s Gut Microbes

    Frank Maixner, a microbiologist at the Institute for Mummies and the Iceman in Italy, explains the significance of the gut microbes of the Ötzi the Iceman, a 5,300-year-old mummy found frozen in a European glacier in 1991. When they tested the contents of his stomach, scientists found Helicobacter pylori, an age-old bacterium that evolved differently according geographic region.

  • The Beautiful, Invisible World of Microbes

    Check out this video compilation of the 2015 Nikon small world in motion competition winners that shows our beautiful, and often time ruthless, microscopic universe.

  • Experience Changes Biology

    New study concludes that the cell is a machine for turning experience into biology.

  • How Epigenetics Controls Behavior

    Researchers Shelley Berger and Daniel Simola describe how they used epigenetics to change the behavior of ants. Ants have a structured workforce where smaller ones, called minors, tend to forage for food; larger ants, called majors, act as soldiers.

  • How To Stop Hangovers (With Science)

    New Year’s Eve is right upon us. Here is some scientific advice on how to prevent a hangover whenever you celebrate a little too hard.

  • Can Lab-Grown Super Corals Save The Ocean?

    Coral reefs are an important part of the ecosystem, but they are struggling to survive in changing oceans. Can lab-grown super-performing corals save the seas?

  • Human Face Evolution In Last 6 Million Years

    One of our earliest ancestors, Orrorin tugenensis, lived around six million years ago in Kenya. Over this time period the human face has evolved and changed markedly.

  • Finally Proof of Global Warming

    More than 190 countries are meeting in Paris next week to create a framework for addressing climate change and to implement a process to reduce greenhouse gases over time. There are lots of indications that global warming is for real.

  • Genetically Modified Dogs: Chinese Scientists Use CRISPR to Create Muscly Freaks

    Researchers working in the Key Laboratory of Regenerative Biology at the Guangzhou Institutes of Biomedicine and Health claim to be the first to use genome modification to double the muscle mass of dogs.

  • 3D Printing of Brains, Veins, and Hearts

    3D printers can replicate hard, bony body parts for use as implants in personalized medicine. But printing soft, flexible, and functional biological materials that can support their own weight during the printing process has remained a challenge. Now, Carnegie Mellon University engineers offer a solution: hydrogels that provide structural support for the biological replicas as they're being created.

  • Lessons of the Brain: the Phineas Gage Case

    The story of Phineas Gage illustrates some of the first medical knowledge gained on the relationship between personality and the functioning of the brain's frontal lobe. A construction foreman from Vermont, Gage survived an accident while laying railroad tracks, during which a 13-pound tamping iron blew straight through his head. Gage’s skull, along with the tamping iron that bore through it, are conserved at the Warren Anatomical Museum, which is a part of the Center for the History of Medicine in the Francis A. Countway Library of Medicine at Harvard. 

  • Ultrasound Drug Delivery

    Researchers at MIT are using ultrasound waves to enable the rapid delivery of drugs to the gastrointestinal tract. This approach could make it easier to administer therapeutics to patients suffering from GI disorders.

  • The Science of Addiction

    Addiction is a biological-based process where the brain plays the critical role. Addictive behavior can translate into positive or negative responses depending on the source of the addictive stimulus. A set of complex reactions is involved in the neurological pathways underlying addiction.

  • Cellular Reception: Engineering Tissues to Rebuild Bodies

    Regenerating new organs and tissues is one of the “hottest” and most rapidly growing areas of biotechnology research. Tissue engineers around the globe are employing techniques such as are tissue scaffolding, 3D printing, and organ-on-a-chip technology.
