Cells’ Collective Behavior Determines Tissue Shapes

A team of researchers, including Northwestern Engineering’s Madhav Mani, has brought the world closer to understanding how living tissues and cells arrive at their...

Bacteria Stab Amoebae with Daggers

Bacteria have to watch out for amoeba. Hungry amoebae hunt them: they catch them with their pseudopodia and then absorb and digest them. However, some...
Regenerative Medicine

NYU Scientists Invent New Protein for Regenerative Medicine

“How,” crooned British pop band the Bee Gees to their fans in the 1970s, “can you mend a broken heart?” Well, those working in...

Chemical Profile of Ants Adapts Rapidly

The bodies of ants and other insects are covered with a thin, wax-like layer that protects them from desiccation and enables them to exchange...
animal colouration

The Biology of Colour

In a wide-ranging and comprehensive review, published inScience last week, a group of evolutionary biologists, behavioural ecologists, psychologists, optical physicists, visual physiologists, geneticists and...
Antarctica

Laser Mapping Project Shows Effects of Physical Changes in Antarctica’s Dry...

Researchers funded by the National Science Foundation (NSF) have publicly released high-resolution maps of Antarctica's McMurdo Dry Valleys, a globally unique polar desert. The high-resolution...
symbiosis

Hostage Situation or Harmony? Researchers Rethink Symbiosis

Relationships where two organisms depend on each other, known as symbiosis, evoke images of partnership and cooperation. But a new study in Nature Ecology...
fungi

Yale Researchers Use New Techniques to Pinpoint Evolution in Fungi

Authors from Yale and Michigan State University collaborated on a National Science Foundation study of five types of fungi that has illuminated a successful...

How Migrating Birds ‘Run a Marathon,’ Burning Muscles and Organs in...

Migrating birds complete long non-stop flights of many hours for songbirds and days for some shorebirds to reach breeding or wintering grounds. During such...

Decoding Ants’ Coat of Many Odors

Ants are covered with a “coat of many odors.” It’s a waxy layer that covers their bodies and is the source of the complex aromas...
Leishmaniasis

Skin Plays Significant Role in Spread of Leishmaniasis

Visceral leishmaniasis is a parasitic infection that kills 20-40 thousand people each year across 56 countries, mainly in the developing world. There is no...
Fruit Fly

Variation at a Central Metabolic Gene Influences Male Fruit Fly Lifespan

The overexpression of an important gene that regulates energy metabolism can cause a severe shortening of lifespan in male fruit flies but has only...
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...

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’ 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...

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...

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...

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...
