"Our goal was to see how chimpanzees, bonobos, and gorillas react to unfamiliar objects in the wild since novel object experiments are often used in comparative psychology research, and we wanted to know if there were any differences among the three great apes," says Ammie Kalan, a primatologist at the Max Planck Institute for Evolutionary Anthropology. "We were specifically surprised by the differences in reactions we observed between the chimps and bonobos.
IQ in childhood is a better indicator of adult wealth than math for very preterm and very low-weight babies, according to a new study in PLOS ONE.
These findings contrast with previous evidence suggesting the specific importance of math skills for economic achievement.
It has been known for decades that cancer cells have an altered metabolism and it is seen in several biochemical pathways and in particular, in the way they get energy for their survival.
If healthy cells use the mitochondrial respiratory chain, tumors use aerobic glycolysis, a process that allows them taking energy quickly but depending on glucose. This phenomenon -known as the Warburg effect- is caused by several changes that take place during cell transformation.
Many phenomena occurring in nature and industry happen very quickly: a tear running through a piece of fabric, a rubber ball bouncing off a hard floor, a drop of water wetting a dry surface and a piece of scotch tape peeling off, for example. Capturing images of these phenomena would help scientists better understand them, but conventional cameras aren't fast enough - and high-speed cameras are prohibitively expensive.
AUGUSTA, Ga. (March 13, 2019) - Our bodies are continuously concocting specific antibodies to thwart invaders like a virus or even pollen, and scientists have new information about how the essential production gets fired up and keeps up.
It's a key protective mechanism that the scientists want to better understand with the long-term goal of manipulating it to help keep us well, says Dr. Nagendra Singh, immunologist in the Department of Biochemistry and Molecular Biology at the Medical College of Georgia at Augusta University.
BEER-SHEVA, ISRAEL...March 13, 2019 -An international team of researchers from Ben-Gurion University of the Negev, the University of Oxford and University of Birmingham have found that internet search patterns and rhythms reflect seasonal interest in plants and animals.
This surprise finding, published in PLoS Biology, suggests new ways to monitor changes in the world's biodiversity based on monitoring internet searches and may provide a roadmap for conservation around the world.
Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study comes out March 13 in Scientific Reports.
WEST LAFAYETTE, Ind. -- Someone could hack into your pacemaker or insulin pump and potentially kill you, just by intercepting and analyzing wireless signals. This hasn't happened in real life yet, but researchers have been demonstrating for at least a decade that it's possible.
Before the first crime happens, Purdue University engineers have tightened security on the "internet of body." Now, the network you didn't know you had is only accessible by you and your devices, thanks to technology that keeps communication signals within the body itself.
University of Oklahoma neuroscientists have found a pathway in the brain where taste and pain intersect in a new study that originally was designed to look at the intersection of taste and food temperature. This study was the first time researchers have shown that taste and pain signals come together in the brain and use the same circuitry. OU neuroscientists received a five-year, $1.6 million National Institutes of Health grant to study this concept.
In a time of drastic change, humans look for predictability. A recent study led by a University of Wyoming researcher found that even in dramatically changing climates, mechanisms can be found that predict how those changes will play out. The last ice age was 11,000 years ago and, since then, climates have continuously changed, triggering constant shifts in the landscape.
Philadelphia, March 12, 2019--For more than two decades, mutations in a gene located in the DNA of mitochondria have been classified as a mitochondrial disease and linked to a particular set of symptoms. However, according to new findings from researchers at Children's Hospital of Philadelphia (CHOP), mutations in this gene, which encodes an essential part of the mitochondrial motor known as ATP synthase that generates cellular energy, are much more variable than previously thought.
Robot-aided rehabilitation represents a step forward for patients with walking difficulties. However, its high price, together with some adaptation and transfer problems, keep limiting its use at present.
In this regard, the Embedded Systems Engineering Group of the University of Malaga, specializing in the design of physical devices to aid users, such as a smart wheelchair, has developed a mechanized cane that can measure patients' rehabilitation process without any impact on them.
In the majority of studies carried out until now Life-Cycle Assessment (LCA) has been used according to a methodology based on the final evaluation of an already finished design. This article proposes a new approach of using LCA as an evaluation tool at the time of design, so making environmental-impact reduction criteria part of the decision-making process in projects so that they affect the final outcome.
Personality in humans has been a well-known concept for long, but during the last two decades science has shown us that also other animals express personalities, for example, in sociability. Differences in personality between the sexes is also a topic in behavioural biology, but besides primates, little is known about personality differences between sexes in long-lived highly social mammals, as studies tend to focus on shorter lived species.
Most laypersons are familiar with the three states of matter as solids, liquids, and gases. But there are other forms that exist. Plasmas, for example, are the most abundant form of matter in the universe, found throughout our solar system in the sun and other planetary bodies. Scientists are still working to understand the fundamentals of this state of matter, which is proving to be ever more significant, not only in explaining how the universe works but in harnessing material for alternative forms of energy.
