A team of researchers, led by the University of Bristol, has revealed our most ancient ancestors were ecologically diverse, despite lacking jaws and paired fins.
Long before they evolved out of the water, our ancient ancestors were simple fish-like creatures, but without fins or chins, who survived by filtering nutrients from sediment.
A tiny flatworm found commonly on the coasts of western Europe and North America is living proof that species may be able to evolve and adapt to rapid climate change.
Research by the University of Plymouth examined the extent to which the intertidal flatworm Procerodes littoralis was able to regenerate and repair itself when challenged with different sea water conditions.
Repeating a study conducted more than a century earlier it was shown that the response of individuals had changed markedly since then.

The human gut contains a diverse ecosystem of microbes: mainly bacteria, as well as viruses and fungi, termed the gut microbiota. Recent years have shown that the gut microbiota have widespread effects on the overall functioning of the host's body.
Normally infants receive gut bacteria from the mother at birth. Some of these maternal bacteria grow out in the infant as they aid the infant in digesting breast milk.
The evolution of epidemic and endemic strains of the cholera-causing bacterium Vibrio cholerae in Argentina has been mapped in detail by researchers at the Wellcome Sanger Institute, the London School of Hygiene and Tropical Medicine, the University of Cambridge and the INEI-ANLIS "Dr Carlos G. Malbrán", Argentina. The teams used whole genome sequencing to study the bacteria circulating during the 1991-1998 outbreak of cholera in the country.
A study published in Science on October 2 suggests that prioritizing aquatic environments in conservation programs for the Amazon region can be up to six times more efficient than focusing on the protection of terrestrial species, as is usual.
A study in mice conducted by the UAB shows that social isolation worsens the effects of Alzheimer's disease, with hyperactivity levels reaching up to twice as much as in the pathology itself
- The research also confirms an increase in the asymmetric atrophy of the hippocampus, a brain area central to memory
COLUMBUS, Ohio -- We hear sounds in part because tiny filaments inside our inner ears help convert voices, music and noises into electrical signals that are sent to our brains for processing. Now, scientists have mapped and simulated those filaments at the atomic level, a discovery that shed lights on how the inner ear works and that could help researchers learn more about how and why people lose the ability to hear.
A group of researchers at the University of Ottawa has been looking for ways to improve enzyme design methodologies and recently published their findings in Nature Communications.
When a star unleashes as much energy in a matter of days as our Sun does in several billion years, you know it's not going to remain visible for long.
Like intergalactic paparazzi, NASA's Hubble Space Telescope captured the quick, fading celebrity status of a supernova, the self-detonation of a star. The Hubble snapshots have been assembled into a telling movie of the titanic stellar blast disappearing into oblivion in the spiral galaxy NGC 2525, located 70 million light-years away.
You could say Seattle came alive with more than an even flow of tourism dollars from a pair of highly-anticipated Pearl Jam concerts, according to rockin’ new research by West Virginia University economists.
More than 100 million infections of Zika virus within Central and South America and the Caribbean went undetected between 2015 and 2018, according to a new study.
The University of Notre Dame researchers who conducted the study, published in PLOS Neglected Tropical Diseases, said the results show a need for improvements to current infectious disease surveillance systems. The study also provides insight into the potential severity of future outbreaks and the current state of herd immunity of Zika in the West.
Many marketing studies have examined the impact of direct-to-consumer advertising of pharmaceuticals on sales and market shares. But in a new study, a researcher from The University of Texas at Dallas wanted to know whether drug advertising might have some unintended, population-level health consequences.
Religious hospital policies that restrict reproductive health care are poorly understood by patients, according to a new study published Sept. 17 in AJOB Empirical Bioethics.
Researchers from the University of Chicago and the University of California, San Francisco found that women value clear information shared early from their health care providers to help them anticipate religious restrictions before their care becomes urgent.
Research from the University of Kent's School of Economics sheds new light on a long-standing obstacle to improving agricultural productivity in developing countries: the reluctance of small-scale farmers to adopt modern technologies because of the risks associated with them.
The paper, published in Science Direct, examined the relationship between attitudes towards risk among small-scale aquafarmers in Ghana and the time they take to adopt new technologies that reduce traditional risks, including; poor weather conditions, aquatic predators and poor hygiene.
