Now, thanks to the dinosaur fossils for sale at Mini Museum , you can build your own private collection of rare dinosaur bones without spending an insane amount of money. Since its launch in 2014, Mini Museum has been making miniature collections of rare and
Electrons in "chiral crystals", solid-state materials with definite "handedness", can behave in unexpected ways. An interdisciplinary team has realized now a theoretically predicted peculiar electronic state in a chiral compound, PtGa, from the class of topological materials. The study allows a fundamental understanding of the electronic properties of this novel semimetal.
Researchers have developed a family of soft materials that imitates living creatures. When hit with light, the film-thin materials come alive — bending, rotating and even crawling on surfaces.
If you could squint hard enough to see the microscopic world, you would notice that the coronavirus SARS-CoV-2 is absolutely coated in tiny little spikes . These spikes, each one a protein that can stick and bind itself to a host cell, are key to the coronavirus's unique infectiousness. But now, scientists from Lehigh University, Seoul National University, and the University of Cambridge have man
Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, sharply defined frequencies, can be used to measure the colors of light waves with great precision.
UC San Diego researchers uncovered in mice how IRE1α, a molecule involved in cells' response to stress, determines whether macrophages promote inflammation in the tumor microenvironment. Inflammation is known to promote tumor growth, making IRE1α an attractive target for drug development.

Porous rock containing oil and natural gas are buried so deep inside the earth that shale operators rely on complex models of the underground environment to estimate fossil fuel recovery. These simulations are notoriously complex, requiring highly-skilled operators to run them. These factors indirectly impact the cost of shale oil production and ultimately, how much consumers pay for their fuel.
The 2016 U.S. presidential election is considered a "game changer" for journalists covering the U.S. presidential elections by causing them to dramatically reconsider how they view their role—either as neutral disseminators of information or impassioned advocates for the truth—according to researchers at the University of Missouri's School of Journalism.
Much of what we know about the actions of neuromodulators like oxytocin comes from behavioral studies of lab animals in standard lab conditions. These conditions are strictly controlled and artificial, in part so that researchers can limit the number of variables affecting behavior. A number of recent studies suggest that the actions of a mouse in a semi-natural environment can teach us much more

There are a number of options available to manipulate these microbubbles, including the use of light and sound. Researchers show that it is entirely possible to manipulate microbubbles through the use of "acoustical tweezers".
A team of researchers found that after being exposed to Facebook's tips on how to spot misinformation, people in the United States and India were less likely to say a false headline was true. However, this ability weakened over time, suggesting that digital literacy needs to be taught with regularity.
An international team of scientists and historians has found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source: a massive eruption of Alaska's Okmok volcano, located on the opposite side of the Earth. A new study uses an analysis of tephra (volcanic ash) found in Arctic ice cores to link this period of extreme climate in the Mediterranean with the ca
Smoking, divorce and alcohol abuse have the closest connection to death out of 57 social and behavioural factors analyzed in this study. The researchers analyzed data collected from 13,611 adults in the U.S. between 1992 and 2008, and identified which factors applied to those who died between 2008 and 2014. They intentionally excluded biological and medical factors.
By studying an individual with an extremely rare brain anomaly that prevents him from seeing certain numbers, Johns Hopkins University researchers provided new evidence that a robust brain response to something like a face or a word does not mean a person is aware of it.
For most of human history our understanding of how planets form and evolve was based on the eight (or nine) planets in our solar system. But over the last 25 years, the discovery of more than 4,000 exoplanets, or planets outside our solar system, changed all that.
Virginia Tech researchers studying how a usually benign virus attacks the human heart with sometimes fatal consequences determined that the virus disrupts the heart's electrical system — and with dual impacts not previously recognized.
A research team led by the USF Health Heart Institute, University of South Florida, identified a mouse model that thoroughly mimics HFpEF syndrome in humans.

Sometimes, when something is broken, the first step to fixing it is to break it even more. Scientists have discovered this is the case for a DNA-repairing enzyme that marks then further breaks damaged DNA. Their surprising findings have provided much-needed insight into how DNA repair works in healthy cells, as well as how different mutations can translate into different diseases and cancer.
Virgin Galactic announced it has signed a deal with NASA to develop a "private orbital astronaut readiness program" that trains and supports private astronauts for missions to the International Space Station.

Molecular clock dates for the first animals to walk the Earth don't match the fossil record. Comparing the disparate DNA of two different species and extrapolating how long it would take for them to mutate from a common ancestor suggests animals existed 833-650 million years ago, but the oldest animal fossils discovered so far only date back 580 million years. One explanation is shortcomings in th

During the COVID-19 pandemic, one unexpected outcome in cities around the world has been a reduction in air pollution, as people stay home to avoid contracting the coronavirus. Based on data collected in Delhi, India, researchers report that this cleaner air has led to more sunlight reaching solar panels, resulting in the production of more clean energy. The work appears June 19 in the journal Jou
Traveling restraints and shelter-in-place orders that grounded planes and emptied streets during the first wave of the COVID-19 pandemic brought greenhouse gas emissions down and air quality up. In a commentary in Joule, environmental economists argue COVID-19 may seem like a "silver lining" for climate change in the short run, but in the long run it is more likely to harm the climate due to its p

Social distancing during the COVID-19 pandemic has not led to an overall increase in loneliness among Americans. That's the takeaway from a comprehensive, nationwide study by Florida State University College of Medicine researchers who surveyed more than 2,000 people before and during the enactment of stay-at-home policies in response to the COVID-19 pandemic.
Much of what we know about the actions of neuromodulators like oxytocin comes from behavioral studies of lab animals in standard lab conditions. These conditions are strictly controlled and artificial, in part so that researchers can limit the number of variables affecting behavior. A number of recent studies suggest that the actions of a mouse in a semi-natural environment can teach us much more
What did the very first proteins look like — those that appeared on Earth around 3.7 billion years ago? Prof. Dan Tawfik of the Weizmann Institute of Science and Prof. Norman Metanis of the Hebrew University of Jerusalem have reconstructed protein sequences that may well resemble those ancestors of modern proteins, and their research suggests a way that these primitive proteins could have progres
A new study of the plant that produces robusta coffee suggests its heat tolerance has been consistently overestimated. Worse yet, when temperatures just slightly cross this point, yields plummet. The findings suggest the multibillion-dollar coffee industry could be facing a much tougher future on even a slightly warmer planet.

The Earth‐moon system's history remains mysterious. Scientists believe the system formed when a Mars‐sized body collided with the proto‐Earth. Earth ended up being the larger daughter of this collision and retained enough heat to become tectonically active. The moon, being smaller, likely cooled down faster and geologically froze. The apparent early dynamism of the moon challenges this idea.
Earth's geographical surfaces formed over millions of years, and various theories aim to explain their formation. The most popular theory, called plate tectonics, states that Earth's outermost layer is a dynamic system consisting of slowly moving plates, also known as tectonic plates. As theses plates move, they come close to each other and collide, or drift away from or slide past each other, cau
Writing for prominent outlets, journalists have mostly sought out male voices to explain, interpret, and otherwise makes sense of the viral pandemic. This has prompted some female researchers to worry that hard-won progress for women in science will become "collateral damage of this crisis."
