Researchers have described the results of experiments that used artificial neural networks to predict with greater accuracy than ever before how different areas in the brain respond to specific words. The work employed a type of recurrent neural network called long short-term memory (LSTM) that includes in its calculations the relationships of each word to what came before to better preserve context.

Researchers have demonstrated for the first time a way to make a robot composed of many loosely coupled components, or 'particles.' Unlike swarm or modular robots, each component is simple, and has no individual address or identity. In their system, which the researchers call a 'particle robot,' each particle can perform only uniform volumetric oscillations (slightly expanding and contracting), but cannot move independently.

Healthy cognitive aging is a public health priority, especially as the US population grows older. Until now, not much has been known about the link between pregnancy history and cognitive function in older women. A new study finds that there does not appear to be a link.

It's spring already? Physics explains why time flies as we age

Researchers have a new explanation for why those endless days of childhood seemed to last so much longer than they do now -- physics. According to the theory, the apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are obtained and processed by the human brain as the body ages.

A mating war in diving beetles has stopped the evolution of species

In nature, males eager attempts to mate with females can be so extreme that they will harm females. Such negative impact of mating interactions has been suggested to promote the emergence of new species under some circumstances. Surprisingly, one type of diving beetle species now show that this conflict between the sexes can instead lead to an evolutionary standstill in which mating enhancing traits in males and counter-adaptations in females prevent the formation of new species.

Chromatin changes rapidly in response to low oxygen

A study reveals new insights into how cells respond to oxygen deprivation. The researchers found that chromatin, the complex of DNA and proteins where all genes reside, quickly changes in response to low oxygen.

Local extinction of Southern California mountain lions possible within 50 years

Two isolated mountain lion populations in southern California's Santa Ana and Santa Monica Mountains are at risk of local extinction, perhaps as soon as within 50 years, according to a study published in the journal Ecological Applications. The extinction risk is due to low genetic diversity and mortality that affects the stability of the population. But increasing connectivity could help.

'Chronoprints' identify samples by how they change over space and time

Modern analytical tools like mass spectrometers can identify many unknown substances, allowing scientists to easily tell whether foods or medicines have been altered. However, the cost, size, power consumption and complexity of these instruments often prevent their use in resource-limited regions. Now, researchers report that they have developed a simple, inexpensive method to identify samples by seeing how they react to a change in their environment.

Parkinson's disease is a neurodegenerative disorder that leads to progressive brain cell death and extensive loss of motor function. Despite much research being conducted on this disease, there are no definitive diagnostic tests currently available. Now, researchers report the identification of compounds that make up the signature odor of the disease with the help an individual who can detect Parkinson's through smell.

With the release of youth football-helmet ratings -- consumers can see which helmets best reduce concussion risk.

The recent spread of coyotes across North America did not doom deer populations

Coyotes eat deer, but not enough to limit the deer population at a large scale. A new study of deer numbers across the eastern United States has found that the arrival and establishment of coyote predators has not caused the number of deer harvested by hunters to decline.

Effects on offspring of epigenetic inheritance via sperm

As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene expression be passed on from parents to their children and subsequent generations? Researchers have now demonstrated that epigenetic information carried by parental sperm chromosomes can cause changes in gene expression and development in the offspring.

Water is a source of concern for disseminating the bacteria Legionella pneumophila and Mycobacterium avium, which cause lung disease (legionellosis and pulmonary nontuberculous mycobacterium disease, respectively). A new study has examined the presence of these microbes in tap water from residences and office buildings across the United States.

Wildlife tourism may negatively affect African elephants' behavior

Increasing numbers of tourists are interested in observing wildlife such as African elephants, and income generated from tourism potentially aids in the protection of animals and their habitats. However, a new study reveals that wildlife tourism may be a stressor for free-ranging elephants.

Skin diseases are more common than we think

Skin diseases are ranked as the fourth most common cause of human illness, but many affected people do not consult a physician. A new study estimates the prevalence of skin diseases outside the typical medical setting.

Purdue University researchers have developed a process to remove nearly all traces of oil in produced water.

Cities rethink parking as ride-hailing grows and parking revenue declines

A new study found that people who use ride-hailing are willing to pay more to avoid driving, including the stress and cost of parking. As a result, cities are seeing a reduction in parking demand, particularly at restaurants and bars, event venues, and airports. That reduction could push cities to reconsider and replace parking infrastructure, leading to more vibrant cities and less dependency on cars.
