It is fascinating to wonder how these effects might play out in the real world, particularly in international politics. By Christian Jarrett

A study published Wednesday in the journal Environmental Research found symptoms of Alzheimer’s disease in babies less than a year old in Mexico City—suggesting not only that the disease takes shape earlier on than previously suspected but that environmental factors may be to blame. The researchers, led by Lilian Calderón-Garcidueñas at the University of Montana, investigated the autopsies of 203 Mexico City residents between the ages of 11 months and 40 years old.

Is it possible that modern humans aren't the first civilization on Earth? This is the insanely interesting question probed by "The Silurian Hypothesis", a new paper authored by Gavin A. Schmidt and Adam Frank, two NASA scientists. As they point out, if an industrialized civilization existed in the deep past, it's not clear there'd be easily recognizable traces of it. Our geologic record doesn't go back any further than the Quaternary period of about 2.6 million years ago.

The trail may start with YlnMn, the first blue created in two centuries.

Birds living in urban areas rarely get any peace and must cope with almost constant disturbance from both humans and their pets

Two new papers find that the line that divides the moist East and arid West is edging eastward due to climate change—and the implications for farming and other pursuits could be huge.

One strange piece of mobile DNA has spread itself throughout the oceans, claiming real estate in the genomes of clams, fish, and more

Perhaps the enduring wintry weather that has consumed much of North America well into springtime could have some positive effects on the human body. New evidence from investigators at the University of Tokyo and Tohoku University in Japan has revealed a molecular mechanism that controls how lifestyle choices and the external environment affect gene expression. This mechanism includes potential targets for next-generation drug discovery efforts to treat metabolic diseases, including diabetes and obesity.

As much as 25 percent of Antarctica’s annual ice melt is occurring during the winter months despite subzero temperatures averaging -48°C (56°F) during the continent’s coldest months

As Techdirt has pointed out a number of times, attacking the huge free online repository of academic papers, Sci-Hub, is wrong from a number of viewpoints. It's wrong because Sci-Hub is not a site aiming to profit from the labor of others, but is...

MIT biologists have discovered the first cellular response targeted at helping mitochondria when their protein import goes wrong.

An employee of Tokyo Electric Power Company says even a flood barrier would not have prevented tsunami from inundating the Fukushima Daiichi nuclear plant following the huge earthquake in 2011. The employee was testifying at the Tokyo District Court on Tuesday in the trial of 3 former TEPCO executives, including former chairman Tsunehisa Katsumata. The 3 are accused of professional negligence resulting in death and injury, in connection with the nuclear accident.

In a few centuries, the planet's largest animal might be a cow, a new study says.

Depression affects approximately 322 million people worldwide, making it the largest contributor to global disability. However, the fact that depression is an actual illness rather than a mood is only beginning to gain traction. Advances in the genetic basis of depression is helping that happen: In 2015 scientists discovered the first two genetic markers linked to the development of major depressive disorder, and on Monday, researchers reported in a new study that the genetic link is even more profound.

Baker’s yeast, brewer’s yeast, yeast that lives in infected toenails—they all descended from a common ancestor.

Thirty-one percent of respondents believed that two million or fewer Jews were killed in the Holocaust, and 41 percent didn’t know what Auschwitz was.

At some point, sweet potatoes crossed the Pacific. This much we know. As for the rest—How? When? Why?—we’re just not sure. Or, to be more clear, some people are sure they’re sure, and others disagree. Sweet potatoes have been at the center of a massive archaeological debate for many decades now, and a new paper has only stoked the flames.

More than a third of mice examined in a new report contained potentially harmful bacteria.

The mystery behind how birds navigate might finally be solved: it's not the iron in their beaks providing a magnetic compass, but a newly discovered protein in their eyes that lets them

A new study reports people who sit down too much during middle to older age show signs of thinning in the medial temporal cortex, an area of the brain associated with the formation of new memories.

Inbreeding and male infertility could be impeding the recovery of one of New Zealand's threatened birds - the stitchbird, or hihi. Hihi sperm might hold the answer, and help raise funds for conservation.

Exclusive: 71 million people stand to benefit from reduced price treatment for virus which can lead to liver cirrhosis, cancer and death

Bad news for "night owls": Those who tend to stay up late and sleep in well past sunrise are at increased risk of early death, a new study suggests.

NEW YORK -- More than one-fifth of millennials in the U.S. -- 22 percent -- haven't heard of, or aren't sure if they've heard of, the Holocaust, according to a study published Thursday, on Israel's Holocaust Remembrance Day. The study, which was commissioned by The Conference on Jewish Material Claims Against Germany and conducted by Schoen Consulting, also found that 11 percent of U.S. adults overall haven't heard of the Holocaust or aren't sure if they did.

An aggressive typhoid strain, resistant to five types of antibiotics, is expected to replace other endemic strains worldwide. It could evolve to become untreatable.

Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.

Targeting a small population of cells seems to be enough for some big effects.

Andrew Jaffe probes Carlo Rovelli’s study arguing that physics deconstructs our sense of time.

Synthetic diamonds account for a small portion of the current market, but with growing interest in ethical diamonds, that could change.

If we want quantum computers, we're going to need a complex system of quantum entangled particles - particles that are intrinsically linked so that whatever happens to one instantaneously affects another.

By making the first progress on the “chromatic number of the plane” problem in over 60 years, an anti-aging pundit has achieved mathematical immortality. By Evelyn Lamb.

A report prepared as part of the police investigation into the Grenfell Tower fire has uncovered calamitous deficiencies in the installation of the windows, cavity barriers and cladding system, and their failure to meet building regulations. The 210-page interim document, by fire investigation experts BRE Global, is set to dramatically assist the Metropolitan police in their wide-ranging investigation. It was leaked exclusively to the Standard and recounts in forensic detail how the original concrete building was turned from a safe structure into a tinderbox by the refurbishment between 2014 and 2016.

That's according to a new survey of young people who said they use the devices.
