DNA

We Are Much More Unique than Assumed

Every human being has a unique DNA "fingerprint". In other words, the genetic material of any two individuals can be clearly distinguished. Computational biologists...
muscle cells

Using Light to Reach Higher Precision in Cell Mechanic Research

Not only muscle cells, but also all other cell types continually generate forces in the human body. An interdisciplinary cooperation of biologists and physicists...
big data

’Big Data’ Resource Raises Possibility of Research Revolution

The Image Data Resource (IDR) is a collaboration between scientists in the Open Microscopy Environment (OME), based at Dundee, and groups at Universities of...
Cell Stiffness

Rensselaer Team Develops a New and Practical Method to Measure Cell...

A team including researchers at Rensselaer Polytechnic Institute has developed an innovative approach to measuring cellular mechanical properties (i.e., cell stiffness) that is part...
coextinction

New Study Upends Established Models of Forecasting Coextinction in Complex Ecosystems

A study from Iowa State University researchers casts new light on how biologists understand the likelihood of coextinction among plants and animals that depend...
parasites

Tropical Plant Combats Parasites in Chickens

A new treatment of the widespread chicken parasite, the Ascaridia galli roundworm, is based on a tropical plant extract. The treatment—currently patent pending—is based...
gene expression

Cells Calculate Ratios to Control Gene Expression

In multicellular animals, cells communicate by emitting and receiving proteins, a process called signaling. One of the most common signaling pathways is the transforming...
ocean

The Ocean Detectives

Marine microorganisms pose a research challenge for biologists, since many of these microorganisms cannot be grown in the laboratory. One way to study them...
bacterial flagellum

How Nature Engineered the Original Rotary Motor

The bacterial flagellum is one of nature’s smallest motors, rotating at up to 60,000 revolutions per minute. To function properly and propel the bacterium,...
animals’ bones

The Dangers of Being a Saber-toothed Cat in Los Angeles 12,000...

Saber-toothed cats that roamed Los Angeles 12,000 years ago had many injuries to their shoulders and backbones that likely occurred when they killed large...
Gut Bacteria

Synthetic Biologists Engineer Inflammation-sensing Gut Bacteria

Synthetic biologists at Rice University have engineered gut bacteria capable of sensing colitis, an inflammation of the colon, in mice. The research points the...
species

Model Predicts Number of Species yet to Be Discovered, Regionally

Many scientists have developed models to predict the total number of species on Earth—including those not yet discovered—of an animal or plant group, but...
vaccines

Virus Hydrophobicity Can Help Purify Vaccines

The complex structures making the surface of a virus are small weaves of proteins that make a big impact on how a virus interacts...
spinal tissue

Engineer Aims to Grow Spinal Tissue in Lab

For a soldier who suffered a spinal cord injury on the battlefield, the promise of regenerative medicine is to fully repair the resulting limb...
parasitic fish

Parasitic Fish Offer Evolutionary Insights

Lamprey are slimy, parasitic eel-like fish, one of only two existing species of vertebrates that have no jaw. While many would be repulsed by...
proteins

Like Elephants, Large Working Proteins Have Small Handlers

A graduate student’s surprise observation in fundamental experiments with small binding molecules at work in protein folding has allowed biochemists at the University of...
retina

Fish Eyes May Hold Key to Regenerating Human Retinas

If you were a fish and your retina was damaged, it could repair itself and your vision would be restored in a few weeks. Sadly,...
biosensors

Environmental Researchers Are Developing New Biosensors for Testing Water

Biologists from the University of Tübingen are part of an interdisciplinary team which has developed novel biosensors that enable pharmaceutical products to be detected...
food waste, weight gain, ultrathin graphene, Idiopathic intracranial hypertension, biopolymer, Memory limits, brain cancers, robots, sperm tails

Moss Biopolymer Reveals How Plants First Colonized Land

A new study of mosses brings scientists one step closer to solving a mystery in plant biology: how plants made the transition from water...
cancer

New Cancer Drug Targets Cellular Garbage Disposal

The genomes of cancer cells—cells that do not obey signals to stop reproducing—are riddled with genetic mutations, causing them inadvertently to make many dysfunctional...
