Something big happened to the planet about a million years ago. There was a major shift in the response of Earth's climate system to variations in our orbit around the Sun. The shift is called the Mid-Pleistocene Transition. Before the MPT, cycles between glacial (colder) and interglacial (warmer) periods happened every 41,000 years. After the MPT, glacial periods became more intense—intense enoug
Nature Communications, Published online: 08 November 2021; doi:10.1038/s41467-021-26813-8 Devices able to harvest heat to generate electricity are intensively studied for sustainable energy production. Here, the authors investigate the mechanism of thermo-electrochemical cells via operando magnetic resonance imaging.
When two black holes — or one black hole and a neutron star — get sucked in to each other, they generate one of the most violent and energetic events in the known universe. These events called gravitational waves were famously first predicted by Albert Einstein, who suggested that the energy released would be so large they could disrupt the space-time continuum itself. Since detecting the very fi
After decades of inertial confinement fusion research, a record yield of more than 1.3 megajoules (MJ) from fusion reactions was achieved in the laboratory for the first time during an experiment at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF) on Aug. 8, 2021. These results mark an 8-fold improvement over experiments conducted in spring 2021 and a 25-fold increa
An international team of researchers has found evidence that the troposphere has been getting thicker, pushing the tropopause higher at a continuous rate over the past 40 years. In their paper published in the journal Science Advances, the group describes their analysis of data obtained from weather balloons and GPS observations.
While movies show Earth as existing in a calm, pristine corner of the universe, in reality the near-Earth space environment is dangerous and dynamic. On any given day, hot charged particles and blobs of plasma, called the solar wind, travel from the sun and are deflected by the Earth's magnetic field, causing beautiful aurora around north and south poles. During solar storms, however, the solar wi
Planckian metals have the potential to power high-temperature superconductors, quantum computers and a host of other next-generation technologies. However, these "strange" metals—in which electrical resistance increases linearly with temperature—are notoriously difficult to study, let alone comprehend.
A new study by researchers from Durham University and Yunnan University reveals that penis worms (Priapulida) invented the 'hermit' lifestyle, some 500 million years ago, at the rise of the earliest animal ecosystems in the Cambrian period.

Sales Dominance The best selling electric vehicles aren't electric cars — instead, they're electric bicycles. In fact, a recent report from The New York Times found that Americans bought roughly half a million e-bikes in 2020. For comparison, they bought just 231,000 electric cars during that same time period — and that's a big deal, from an infrastructure point of view, at a moment when policyma
For many, many months now, 7-year-old Alain Bell has been keeping a very ambitious list of the things he wants to do after he gets his COVID-19 shots : travel (to Disneyworld or Australia, ideally); play more competitive basketball; go to "any restaurants that have french fries, which are my favorite food," he told me over the phone. These are very good kid goals, and they are, at last, in sight.

Future fusion reactors have a conundrum: maintain a plasma core that is hotter than the surface of the sun without melting the walls that contain the plasma. Fusion scientists refer to this challenge as "core-edge integration." Researchers working at the DIII-D National Fusion Facility at General Atomics have recently tackled this problem in two ways: the first aims to make the fusion core even ho
The U.S. scientific community is currently conceptualizing the first nuclear fusion power plants, which will revolutionize energy production.

A single bad El Niño weather event can leave nearly 6 million children undernourished, according to a new study. That's at least 70%—and perhaps up to three times—the number of children who have gone hungry because of the COVID-19 pandemic. El Niño events cause weather patterns to shift across the tropics, leading to widespread impacts on agriculture, infectious diseases, and human conflicts and
Stop me if this sounds familiar; NASA's Hubble Space Telescope is experiencing difficulties that caused it to fall back to safe mode last week. This is, of course, far from the first time Hubble has encountered a glitch. NASA just worked past a similar error earlier this year , and now it is again attempting to repair the aging observatory from the ground. Hubble reported an error on October 23rd
The use of telehealth at nursing homes during the COVID-19 pandemic not only reduced stress for some residents, but also increased access to convenient care. But there were some downsides. The pandemic caused nursing homes to rapidly change their policies overnight. Telehealth was instantly adopted widely in an effort to reduce stress on the health care system by keeping residents safe and avoidi
Whether we are consciously aware of it or not, we negotiate in every aspect of our daily lives—whether it be persuading a child to eat its vegetables, haggling over a property price, or discussing the terms of a job offer. Negotiation can be viewed as "back-and-forth communication designed to reach an agreement when you and the other side have some interests that are shared and others that are opp
While getting humans to Mars is likely to be one of the grandest challenges humanity has ever undertaken , getting them back could be even tougher. Researchers think sending genetically engineered microbes to the Red Planet could be the solution . Both NASA and SpaceX are mulling human missions to Mars in the coming decades. But carrying enough fuel to make sure it's a round trip adds a lot of ex
A fatal crowd surge during a performance by US rapper Travis Scott on Friday night has become one of the deadliest live music incidents in recent years. Crowd crushes during the Houston show, which was part of the Astroworld Music Festival, led to eight deaths and dozens of injuries.
When Congress tasked a group of economists and social scientists in 2015 to study ways to cut child poverty in the U.S. in half, one finding stood out. More than any other policy, a "child allowance" of about $3,000 per year, per child—similar to what most industrialized countries provide—would have the most impact, according to the final National Academy of Sciences report.
With the U.N. Council of Parties (COP26) starting in full swing last week, the world was filled with news from the Climate Industry's biggest trade show. These meetings have the value of focusing attention on this critical issue and can motivate corporate and government climate action to demonstrate support of the global climate agenda. Like Earth Day every April, it provides a useful deadline for

Passive solar heating systems could supply enough heat for a third of the residential space in the United States, research finds. Passive solar heating systems collect natural light via skylights or windows and use it to directly heat spaces, without converting it to electricity. The findings, which appear in Renewable and Sustainable Energy Reviews , are the first detailed survey of direct solar
Facebook—its new corporate name is Meta—has always wanted to get to know you. Its public goal has ostensibly been to connect people. It's been wildly successful in doing so by building out what can only be called everyday infrastructure around the world.
Space is an incredibly hostile environment, and we are learning more about the challenges of living and traveling in space the more we study it. Apart from the obvious near vacuum and near absolute zero temperatures, space is full of harmful radiation. We live comfortably beneath a blanket of protective atmosphere and a magnetic shield, but in space we are exposed. Traveling through space adds an
In 2020, for the first time in Australia, more than half the shareholders of a public company voted in support of a climate change resolution put forward by shareholders in the face of opposition from the company's board of directors.
Nature Communications, Published online: 08 November 2021; doi:10.1038/s41467-021-26004-5 It is commonly thought that horizontal transfer of most bacterial chromosomal genes is limited, in comparison with the frequent transfer of mobile genetic elements. Humphrey et al. show that, actually, phage-mediated lateral transduction of core chromosomal genes can be more efficient than the transfer of mo
Shipping, which transports 90% of the world's trade, contributes nearly 3% of global emissions—a little more than the carbon footprint of Germany. If gone unchecked, this share could increase to 17% by 2050 as the world's GDP keeps growing.
Around 56 million years ago, Paleocene-Eocene Thermal Maximum (PETM), one of the most famous historical hyperthermal events, led our planet to a super greenhouse condition. It is very important for us to understand how it happened and how it affected the environment, because studying past climatic events of extreme global warmth may be one of the best ways for us to understand and predict future e
The field of aquaponics has recently yielded a new plant-fish combination. For the first time, a salinity-tolerant plant commonly known as glasswort, or sea asparagus, has been grown together with flathead gray mullet (Mugil cephalus), an important food fish species found in coastal waters worldwide. The experiment was carried out by the Institute of Agrifood Research and Technology (IRTA) at its
Benin's parliament has voted to legalize abortion in most circumstances. This is a groundbreaking move by the west African country given that 92% of women of reproductive age on the continent live in countries which have restrictions—some moderate, some severe—on abortions.

Offentlige it-projekter vokser stødt i omfang og ambitioner, men underestimeres samtidig i tid og budget, mener RUC-professor Jan Pries-Heje. Det fører til, at projekterne konsekvent vil fejle på papiret.
In the race toward practical fusion energy, tokamaks (donut-shaped plasma devices) are the leading concept—they have achieved better confinement and higher plasma temperatures than any other configuration. Two major magnetic fields are used to contain the plasma: a toroidal field (along the axes of the donut) produced by external coils and the field from a ring current flowing in the plasma itself
Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and Los Alamos National Laboratory have uncovered a key process behind a major challenge called thermal quenches, the rapid heat loss in hot plasmas that can occur in doughnut-shaped tokamak fusion devices. Such quenches are sudden drops of electron heat in the plasma that fuels fusion reactions, drops that c
Charged particle accelerators have been a central tool of basic physics research for almost a hundred years, perhaps most famously as "atom smashers" for understanding the elementary constituents of the universe. As accelerators have progressed to ever higher energies to probe ever smaller constituents, they have grown to enormous size: the Large Hadron Collider is a remarkable 27 kilometers in ci
For decades, scientists have been working to harness clean, renewable fusion energy, which occurs naturally in stars like our sun. Using strong magnetic fields to confine hot plasmas within a donut-shaped device called a tokamak, researchers can generate conditions necessary to induce fusion reactions.
Spacecraft have long used heat shields for protection during entry into planetary atmospheres. Future missions to the outer solar system will need more sophisticated materials than currently exist. The extreme heating conditions needed to study new shield materials are, however, very difficult to achieve experimentally on Earth. Scientists working at the DIII-D National Fusion Facility at General
In controlled nuclear fusion, heavy isotopes of hydrogen fuse into helium, releasing a huge amount of energy in the process. A large portion of the energy released by a laboratory fusion reaction goes into hot helium ash (an impurity in the plasma that bears no resemblance to ash from a fire). This ash is around 30 billion degrees Celsius, compared to 200 million degrees for the bulk plasma. For c
The march towards fusion energy gain, required for commercial fusion energy, is not always visible. Progress occurs in fits and starts through experiments in national laboratories, universities, and more recently at private companies. Sam Wurzel, a Technology-to-Market Advisor at the Advanced Research Projects Agency-Energy (ARPA-E), details and highlights this progress over the last 60 years by e

When immune cells move throughout the brain, they act as the first line of defense against viruses, toxic materials and damaged neurons, rushing over to clear out them. Researchers have been investigating how these immune cells in the brain — microglia — relate to a gene mutation recently found in Alzheimer's disease patients.
About 20 years ago, a physicist had an idea to reveal insights about a fundamental but enigmatic force at work in some of the most extreme environments in the universe. These environments include an atom's nucleus and celestial bodies known as neutron stars, both of which are among the densest objects known to humanity. For comparison, matching the density of a neutron star would require squeezing
The largest protein in the human body, titin, enables elastic movements of our muscles, including the heart. Mutations in the titin gene (TTN) that impair this function and lead to heart muscle disease. The pathomechanisms behind this — i.e. why TTN mutations trigger disease — were unclear until now. A team of experts has now investigated these pathomechanisms in more detail and has gained groun
