Researchers at NYIT College of Osteopathic Medicine have discovered stages of cervical elongation in the giraffe family, revealing details about the evolutionary transformation of the neck within extinct species of the family.
A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known example of photosynthesis by living organisms, say University of Wisconsin-Madison geoscientists.
Researchers at the University of Missouri have found that activating the pleasure and reward receptors in the brain could provide the 'reward' of dangerous drugs without having to consume those drugs.
Two studies by cancer scientists at the Ohio State University Comprehensive Cancer Center -- James Cancer Hospital and Solove Research Institute suggest new approaches for treating cancer by inhibiting overactive cancer-promoting genes and by enhancing the activity of sluggish tumor-suppressor genes. The findings were reported in the journals Nature Communications and Nature Genetics.
Responding appropriately to the smell of food or the scent of danger can mean life or death to a fruit fly, and brain circuits are in place to make sure the fly gets it right. A CSHL team has identified an important component in these circuits: the point at which incoming sensory information begins to be transformed into a signal that instructs a fly's response. The cells, MBONs, distill nuanced information about an odor into clear instructions: approach or flee.
New findings have overturned a scientific dogma that stood for decades, by showing that potassium can work with graphite in a potassium-ion battery -- a discovery that could pose a challenge and more sustainable, less costly alternative to the widely used lithium-ion battery.
Research published in the journal Biological Conservation shows that isolated wildlife sanctuaries could be linked by a national network of protected river corridors to provide animals with the spacious, connected habitats they need to thrive. The work provides a unifying solution to the complex, long-standing problem of connecting wildlife conservation areas and necessary habitats over vast areas.
An international team of researchers have designed and synthesized a nanometer-scale DNA 'machine' whose customized modifications enable it to recognize a specific target antibody.
Caltech biologists have developed a nonsurgical method to deliver long-term contraception to both male and female animals with a single shot. The technique -- so far used only in mice -- holds promise as an alternative to spaying and neutering feral animals.
A new discovery published in the journal Scientific Reports documents the intricate arrangement of the muscles and ligaments that controlled the main feathers of the wing of an ancient bird, supporting the notion that at least some of the most ancient birds performed aerodynamic feats in a fashion similar to those of many living birds.
