COLUMBUS, Ohio - A five-minute role-play done with men before the birth of their first child predicted the quality of their parenting after the baby arrived, a new study showed.
Researchers videotaped 182 expectant fathers during the third trimester of their partners' pregnancy, observing how the men interacted with a doll that they were told represented the baby they were about to have.
Every summer, tens of thousands of Atlantic salmon migrate from the Barents Sea to the Teno River, Finland, to spawn in the streams where they were born. This journey is a feat of endurance: salmon stop feeding and must navigate fast flowing water, leap over obstacles, and avoid predators, hooks, and fishing nets to arrive at their spawning grounds.
Blocking a pair of sugar-transporting proteins may be a useful treatment approach for lung cancer, suggests a new study in mice and human cells published today in eLife.
Cancer cells use a lot of sugar to fuel their rapid growth and spread. This has led scientists to consider cutting off their sugar supply as a way to treat cancer. The current study suggests this could be an effective approach but it will be necessary to block multiple pathways at once to be effective.
Throughout California, the effects of climate change are evident from increasing frequencies of intense wildfires and mudslides to widespread and prolonged droughts. These changes also threaten one of California's most iconic endemic species: coastal redwoods. Coastal redwoods are not only some of the tallest and oldest trees on Earth, but redwood forests are also capable of storing three times more carbon than any other forests on Earth. Identifying suitable habitats for these vulnerable species has important implications for carbon sequestration and redwood forest biodiversity.
WEST LAFAYETTE, Ind. -- "Mommy brain" is a long-held perception that mothers are more forgetful and less attentive.
"In most studies, however, attention and memory tests are given to mothers very early postpartum," said Valerie Tucker Miller, a Ph.D. student in Purdue University's Department of Anthropology department. Miller is studying the effects of motherhood on attention, memory and other psychological processes.
WASHINGTON, D.C. (June 23, 2020) - A majority of Americans (63%) continue to say they see the effects of climate change in their own communities, and 65% believe that the federal government is doing too little to reduce the impacts of climate change, according to a new Pew Research Center survey.
With or without physical separation due to COVID-19, youth are using social media to connect and support each other, according to a report released today. Three leading researchers have just published Youth Connections for Wellbeing, an integrative review paper that illuminates how teens support each other through digital media during times of stress and isolation.
What The Studies Did: These studies looked at changes in the rate of traffic fatalities in states that have legalized the use of recreational cannabis.

A new study has highlighted the crucial role that sea ice across the Southern Ocean played in controlling atmospheric carbon dioxide levels during times of past climate change, and could provide a critical resource for developing future climate change models.
The accretion of new material during Pluto's formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day, despite the dwarf planet's orbit far from the sun in the cold outer reaches of the solar system.
This "hot start" scenario, presented in a paper published June 22 in Nature Geoscience, contrasts with the traditional view of Pluto's origins as a ball of frozen ice and rock in which radioactive decay could have eventually generated enough heat to melt the ice and form a subsurface ocean.
Giving people "digital literacy" tips can help them identify dubious information online, a new study shows.
The avalanche of online content available to people around the world challenges humans' ability to separate fact from what can be highly toxic and even dangerous fiction.
Researchers studying Facebook's efforts to educate users on how to spot misinformation have found people in the United States and India were less likely to say a false headline was true after they were exposed to tips on how to spot misinformation
The SARS-CoV-2 outbreak is posing an extraordinary challenge that requires swift worldwide action for the massive deployment of affordable and ready-to-apply measures to drastically reduce its transmission probabilities in indoor spaces, and eventually return to conventional activities such as working at the office, going to school, or even attending entertainment events.
The tsetse fly occurs in large regions of sub-Saharan Africa. The flies feed on human and animal blood, transmitting trypanosoma in the process - small, single-cell organisms that use the flies as intermediate host and cause a dangerous inflammation of the lymph and nervous system in both animals and humans. There is no vaccination for this sleeping sickness; untreated, it usually ends in death. In agriculture, particularly cattle breeding, sleeping sickness - or trypanosomiasis - causes enormous damages in the form of sick and dead animals.
MINNEAPOLIS, MN- June 22, 2020 - While pregnancy and birth rates continue to decline to historic lows for 15 to 19-year-olds, Minnesota youth are contracting sexually transmitted infections (STI) at alarmingly high rates.
SUMMARY
Researchers discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform. Using this method, coined strainoptronics by a team led by George Washington University professor Volker Sorger, the researchers demonstrated for the first time that a 2D material wrapped around a nanoscale silicon photonic waveguide creates a novel photodetector that can operate with high efficiency at the technology-critical wavelength of 1550 nanometers.
