A tidal wave of interest is building in farming the seas. It’s part of a global rush to exploit oceanic resources that’s been dubbed the “blue acceleration.” Optimistic projections say that smart mariculture – fish farming at sea – could increase ocean fish and shellfish production

We see far fewer technical, economic and resource constraints for freshwater aquaculture than for ocean farming, and far greater potential for land-based fish farms to contribute to global food security.

The most important species groups – carp, tilapia and catfish – are herbivorous or omnivorous, so they don’t need to eat animal protein to thrive.

From 2008 to 2020, the average speeds of all major league baseball pitches combined rose by between 1.5 mph and 2 mph.

But MLB pitchers aren’t the only expert throwers; most healthy people can throw faster than our much stronger chimpanzee relatives, who max out at around 30 mph. A study of boys from the ages of 8 to 14 who were only moderately trained in throwing could still throw two times faster than chimps.

Humans are the only species that can throw well enough to kill rivals and prey. Because throwing requires the highly coordinated and extraordinarily rapid movements of multiple body parts, there was likely a long history of selection favoring the evolution of expert throwing in our ancestors.

I Survived 18 Years in Solitary Confinement

Mr. Manuel is an author, activist and poet. When he was 14 years old, he was sentenced to life in prison with no parole and spent 18 years in solitary confinement.

Imagine living alone in a room the size of a freight elevator for almost two decades.

As many as 1 in 5 of the roughly 2.7 million Americans deployed to Iraq and Afghanistan since 2001 are experiencing post-traumatic stress disorder.

Our lab is studying whether service dogs can help these military veterans, who may also have depression and anxiety – and run an elevated risk of death by suicide – in addition to having PTSD.

Unlike emotional support dogs or therapy dogs, service dogs must be trained to do specific tasks – in this case, helping alleviate PTSD symptoms. In keeping with the Americans with Disabilities Act, service dogs are allowed in public places where other dogs are not.

QAnon is often viewed as a group associated with conspiracy, terrorism and radical action, such as the Jan. 6 Capitol insurrection. But radical extremism and terror may not be the real concern from this group.

I noticed that QAnon followers are different from the radicals I usually study in one key way: They are far more likely to have serious mental illnesses.

I found that many QAnon followers revealed – in their own words on social media or in interviews – a wide range of mental health diagnoses, including bipolar disorder, depression, anxiety and addiction.

Between 2006 and 2018, four women served as presidents in the region.

For gender researchers like ourselves, this is a rare chance to assess how the president’s gender influences policy in Latin American countries. Global research has confirmed that having women in the highest echelons of power leads to greater political engagement among women and girls. We wanted to know what Latin America’s four “presidentas” had done to promote gender equality while in power.

Latin Americans who have a woman for president are also much less likely than other respondents to say they think men make better political leaders than women.

Money isn’t everything. But for measuring national success, it has long been pretty much the only thing

And the era of GNP and GDP has been characterized by a huge global rise in living standards and in wealth.

At the moment, though, GDP is embattled. Economists and national leaders are increasingly talking about measuring a country’s status with other metrics and even with a squishy-seeming concept like “happiness.”

Situated on the east bank of the Nile, some 150 miles by car northeast of Sudan’s capital, Khartoum, the Meroe pyramids — around 200 in total, many of them in ruins — seemed to be in perfect harmony with the surrounding landscape, as if the wind had smoothed their edges to accommodate them among the dunes.

was the hope that the country’s archaeological sites might receive broader attention and protections, not simply from researchers and international visitors but also from Sudanese citizens themselves.

A wave of demonstrations filled the streets of several towns, far beyond the capital Khartoum. These were Sudanese of all ethnicities, classes and generations — but above all students and young professionals.

Scientists are examining a possible link to tinnitus. A businessman’s suicide has lent urgency to the research.

Mr. Taylor suffered from a variety of symptoms following his illness, including severe tinnitus, his family said in a statement, adding that his suffering had become “unbearable.”

A study published on Monday in the Journal of International Audiology that looked at nearly 60 case reports and studies found that 15 percent of adults with Covid-19 reported symptoms of tinnitus.

For 50 years, my state denied me the story of my birth. All adoptees deserve better.

In 1968, a woman appeared for an interview at the Children’s Bureau, an adoption agency in Indianapolis

“a very attractive, sweet looking girl,” who seemed “to come from a good background” and was “intelligent.”

Roughly 3 percent of vaccines in the U.S. Virgin Islands have gone to tourists, the governor said this week. “Nowhere else in the U.S. can you actually just walk in and get the vaccine,” he said.

“We were in and out within a matter of a few minutes,” Ms. Todman said. “It was amazing.”

“Have we become aware of the fact that people are seeking us out? Yes. And you know, we accommodate everyone,” said Angela East, the coordinator and director of the Covid-19 vaccine program at Plessen Healthcare, which has administered 44 percent of all Covid-19 vaccines in the territory. “We are going to give you the shot in the spirit of putting as many shots in arms as possible.”

The threat of extinction has diminished the odds of spotting one of these wood-dwelling elephants in recent decades,

The shy forest elephants have lost nearly nine-tenths of their number in a generation and are now critically endangered — just one step from extinction in the wild.

The population of savanna elephants has fallen at least 60 percent, the team found. Forest elephants have declined by more than 86 percent.

Culture matters more than a leader’s gender in how a nation survives a global pandemic, according to a study I conducted on gender and COVID-19 management, which was published in December in the journal PLOS ONE.

We identified no statistically significant differences in deaths based on the gender of the country’s leader.

Instead, we found that pandemic outcomes hinged primarily on how egalitarian a country is.

The assumption has long been that adding lions to the top of the food chain would lead to healthier populations of these other carnivore species, and that any efforts to protect large predators, such as lions, automatically benefit smaller ones, too. However, scientists lack evidence about whether these predictions play out in the real world, especially in small reserves of the sort found in South Africa.

“Apex predators are very interactive in an ecosystem, and we need to take better into account their ecological effect.”

Mr. Curveira-Santos says it is clear that the lions, when they are present, are influencing the distributions of these smaller carnivores.

An experiment by Japanese researchers revealed how just a few distracted walkers really can throw off the movements of a whole crowd.

And so it might not come as too much of a surprise to learn that a person staring down at a phone, lost in a private world while walking, really messes with the vibe, according to a study published Wednesday in the journal Science Advances.

When those students were placed at the back of their group, the distraction did not affect how the groups moved past each other. But when the distracted walkers were at the front of the pack, there was a dramatic slowdown in the whole group’s walking pace. It also took longer for clear lanes to form.

We can find real solutions to gun violence if we recognize the trauma it causes.

In the span of a week, two acts of public violence have stolen the lives of 18 people and provided a stark reminder of the mass gun violence that characterized the pre-Covid United States

Gun violence did not go away during 2020. Gun homicides jumped 25 percent from the year before, apparently fueled in part by a rise in intimate partner violence

Economic justice was not new to his agenda

The March on Washington sought equality before the law, but also an economic bill of rights for poor white, black and brown workers. He had constantly linked civil rights and labor and poor people’s movements; as far back as 1957, he condemned “the tragic inequalities of an economic system which takes necessities from the masses to give luxuries to the classes.”

Trump Administration tax cuts have allowed the wealthiest Americans to pay a lower tax rate than the poorest, and multibillion-dollar companies like Amazon are often able to effectively avoid paying federal taxes.
