China bets big on brain research with massive cash infusion and openness to monkey studies
After 5 years of planning and debate, China has finally launched its ambitious contribution to neuroscience, the China Brain Project (CBP). Budgeted at 5 billion yuan ($746 million) under the latest 5-year plan, the CBP will likely get additional money under future plans, putting it in the same league as the U.S. Brain Research Through Advancing Innovative Neurotechnologies (BRAIN)...
Mars rover nears milestone in ambitious plan to to return first rocks from another planet

China Report: What’s up with all of Biden’s executive orders on China?
Welcome to the very first China Report newsletter! I’m Zeyi Yang, and every Tuesday I’ll bring you news about China’s technology industry. This week, let’s unpack recent actions on China from the Biden administration.
Lately, President Biden has been getting busy with executive orders that are, without naming China, very related to China. In the past three weeks, there have been at...
Fundamental research improves understanding of new optical materials
Research into the synthesis of new materials could lead to more sustainable and environmentally friendly items such as solar panels and light emitting diodes (LEDs). Scientists from Ames National Laboratory and Iowa State University have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material. They...
New research gives potential for more accurate methamphetamine detection
Methamphetamine is a stimulant that can be taken as a recreational drug, either by injections or smoking. It is classified as a Class A drug in the UK and its recreational use is criminalized in many countries throughout the world.
Did life get its start in micaceous clay?
In mythologies and origin stories around the world, various cultures and religions point to clay as the vessel of life, the primordial material that creator gods imbued with a self-sustaining existence. Nowadays we have biology to explain how life comes to be, but could these tales of old hit closer to the mark than we think?
Idaho a step closer to having largest research dairy in US
The University of Idaho's plan to build the nation's largest research dairy and experimental farm cleared a big hurdle on Tuesday.
Proving that quantum entanglement is real: Researcher answers questions about his historical experiments
In the 1930's when scientists, including Albert Einstein and Erwin Schrödinger, first discovered the phenomenon of entanglement, they were perplexed. Entanglement, disturbingly, required two separated particles to remain connected without being in direct contact. Einstein famously called entanglement "spooky action at a distance," since the particles seemed to be communicating faster than the...

Research into the synthesis of new materials could lead to more sustainable and environmentally friendly items such as solar panels and light emitting diodes (LEDs). Scientists have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material and study the surface chemistry of the nanocrystals.
Discovery illuminates how Parkinson's disease spreads in the brain

Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson's disease through a cellular waste-ejection process, suggests a new study.
Fish can help in the search for multiple sclerosis drugs
The zebrafish should be known to many aquarium enthusiasts, mainly because of its striking pigmentation. However, the characteristic black-blue stripes, to which the animal owes its name, only form over time. Its eyelash-sized larvae, on the other hand, are still more or less transparent. Many developmental processes in their bodies can therefore be observed under the light microscope. For this...
‘It’s not a banger’: response to Space Force official song is less than stellar
The new song, Semper Supra, is set to a jaunty tune, but critics say its lyrics are ‘verbal word salad’Space Force, the sixth and newest branch of the US military, unveiled its official song on Tuesday amid a less than stellar critical response.As one website dedicated to covering America’s armed forces put it: “It’s not a banger.” Continue...
From the atom to natural killer cell: The story of an unexpected protein structure
The discovery of a peculiar protein structure and the quest to confirm it has led to the description of interacting receptor clusters on natural killer (NK) cells. The study by the research team of Dr. Ondřej Vaněk from the Department of Biochemistry, Faculty of Science, Charles University, and his colleagues from the Institute of Biotechnology of the Czech Academy of Sciences in the center...
Newly identified small molecules break amyloid tangles that cause Alzheimer's

In lab experiments, researchers observed a molecule called EGCG break up tau tangles extracted from Alzheimer's disease brain tissue EGCG does not, however, easily penetrate the human brain. They found two other molecules -- CNS-11 and CNS-17 -- that work like EGCG to stop tangles spreading cell to cell but are better leads for drugs.
Statistical analysis aims to solve Greek volcano mystery
One of the largest volcanic eruptions in the Holocene epoch—as measured by the volume of material ejected—occurred on the Greek island of Santorini, traditionally known as Thera. It is considered a pivotal event in the prehistory of the Aegean and East Mediterranean region, with the city of Akrotiri, buried some 1,600 years before Pompeii, becoming one of the key archaeological sites of the...
Revealing spacecraft geometry effects on impact simulations for NASA's DART mission
NASA's Double Asteroid Redirection Test (DART) spacecraft will crash into asteroid Dimorphos on Sept. 26, executing the first asteroid deflection test that has been years in the planning.
Lack of public appreciation contributes to loneliness in farming, study shows
A lack of public appreciation for farmers, and an understanding of the work they do and the pressures they're under contributes to feelings of loneliness, according to a new study. The paper, "It's a lonely old world": Developing a multidimensional understanding of loneliness in farming," is published in the journal Sociologia Ruralis.

The zebrafish serves as a model organism for researchers around the world: it can be used to study important physiological processes that also take place in a similar form in the human body. It is therefore routinely used in the search for possible active substances against diseases. Researchers have now described an innovative way to do this. In this process, the larvae fish are made a bit more...

Drumming in woodpeckers is neurologically similar to singing in songbirds
Researchers led by Matthew Fuxjager at Brown University, U.S. and Eric Schuppe at Wake Forest University, U.S. have found regions in the woodpecker forebrain that show characteristics that until now have only been associated with vocal learning in animals and language in humans. Publishing in the open access journal PLOS Biology on September 20, the study shows that instead of being related to...

Liza Fisher is preparing for a busy day. In about an hour, her mother will drive her to a clinic, where she will receive IV fluids and iron treatments for her anemia. When the IV bag is empty, she’ll head to an adaptive gym, where she’ll don compression pants and take a class for people…
Super-resolved coherent Raman spectroscopy with quantum light
In recent years, entangled photons—a popular quantum light source—have been widely used in quantum imaging, optical interferometry, quantum computing, quantum communication, and other fields. Spontaneous parametric down-conversion generates the entangled photon pairs with conserved energy and momentum, so that the quantum correlation in space and time is encoded. Such a property enables a...
