Mane attraction: Molecular 'switch' may control long scalp hair
Treating hair loss may be as simple as developing therapies to flip a molecular "switch," according to a new study by researchers from Penn State; the University of California, Irvine; and National Taiwan University.

A new twist in an old origin story: Earliest dinosaurs may have emerged in the Amazon
The remains of the earliest dinosaurs may lie undiscovered in the Amazon and other equatorial regions of South America and Africa, suggests a new study led by UCL (University College London) researchers.

Solving the evolutionary puzzle of polyploidy: How genome duplication shapes adaptation
Evolution is the basis of biological diversity, driven by mechanisms that allow organisms to adapt and survive. One such mechanism is polyploidy, where organisms carry extra copies of their genomes. While polyploidy provides ...

Azraq Basin fossils reveal mammals shrank during Pleistocene-Holocene climate shift
Earth's climate changed dramatically during the Late Pleistocene and Early Holocene 130,000 to 7,000 years ago, when cold glacial cycles transitioned into the current warmer interglacial. Such a climatic evolution had considerable ...
El Niño drought reveals survival advantage in monkeys with robust stress response
White-faced capuchin monkeys in Costa Rica who experienced more intense physiological responses to mild droughts were more fit to survive extreme drought, researchers found in a new UCLA-led study.

The secret 'sex lives' of bacteria: Study challenges old ideas about how species form
When Kostas Konstantinidis proved that many bacteria—like plants and animals—are organized into species, he upended a long-held scientific belief. Scientists widely believed that bacteria, due to their unique genetic ...

More than 100 years of data suggest men are growing taller and heavier at twice the rate of women
A gender specialist at the University of Genoa, in Italy, a psychologist at the University of Missouri, in the U.S., and a behavioralist at the University of Roehampton, in the U.K, have found that men are growing taller ...
Plants more likely to be 'eavesdroppers' than altruists when tapping into underground networks, study finds
A new study led by the University of Oxford has used a modeling approach to show that it is unlikely that plants would evolve to warn other plants of impending attack. Instead of using their communication networks to transmit ...

Model shows evolution had many optimal outcomes to choose from
Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely theoretical fashion?

Early humans' hunting habits reshaped scavenger communities, study suggests
A new study indicates that human behavior around 45,000 to 29,000 years ago contributed to a change in the composition of scavenging animal species living nearby. While smaller scavenging animals such as foxes and some bird ...

Reversing age-related fertility decline in male fruit flies: The crucial role of seminal fluid
As males age, their reproductive success typically declines. A study on fruit flies, led by University of Oxford researchers, has found that while old males do produce fewer offspring than young males, this is not because ...

How evolutionary adaptations enable a fruit fly to detect and thrive on toxic food sources
The ability to tolerate toxic substances can help animals find new food sources and thrive in certain ecological niches. Researchers at the Max Planck Institute for Chemical Ecology in Jena have now discovered that the fruit ...
