New mechanism proposed for why some psychedelics act as antidepressants
We know what receptors they bind, but where they bind them might matter, too. Enlarge (credit: VICTOR de SCHWANBERG/SCIENCE PHOTO LIBRARY) Psychedelic drugs are often used for entertainment purposes. But there have been.....»»
Apple readies Apple Watch Series 9 ban workaround by disabling blood oxygen functionality
The U.S. Customs agency has handed down its decision on whether Apple’s proposed redesign of the Apple Watch Series 9 and Apple Watch Ultra 2 is enough to circumvent infringing on two Masimo patents related to the blood oxygen sensor. In a fili.....»»
New research deciphers biomineralization mechanism
Many organisms can produce minerals or mineralized tissue. A well-known example is nacre, which is used in jewelry because of its iridescent colors. Chemically speaking, its formation begins with a mollusk extracting calcium and carbonate ions from w.....»»
A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular me.....»»
Study uncovers low-temperature deformation mechanism of pure titanium
Titanium (Ti), often hailed as the wonder metal for its remarkable properties, has many applications in aerospace, marine, and biomedicine industries. Known for their low density, high strength, high ductility, great corrosion resistance, and excelle.....»»
Observing macroscopic quantum effects in the dark
Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists in a recent paper published in Physical Review Letters. An object evolving in a potential created through electrost.....»»
Apple has designed a MagSafe gimbal camera mount for iPhones
A newly-granted patent shows how Apple has at least designed a stand that is specifically for charging an iPhone during filming, and connecting to a gimbal.Two views of Apple's proposed MagSafe camera mount for iPhonesThere was no sign of such a MagS.....»»
Multi-point temperature measurements in packed beds using phosphor thermometry and ray tracing simulations
A team of researchers has proposed an indirect optical method for determining internal temperatures of opaque packed beds based on phosphor thermometry. This method enables simultaneous multi-point measurements using an image-based separation of the.....»»
Researchers discover important membrane transport mechanism in pathogenic bacteria
Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside t.....»»
Big evolutionary change tied to lots of small differences
Lots of genes changed as a species of snail went from laying eggs to live births. Enlarge / An example of a Littorina species, the common periwinkle. (credit: Bjoern Wylezich) The version of evolution proposed by Charles.....»»
Metal-organic frameworks study unravels mechanism for capturing water from air
Researchers from the Helmholtz-Zentrum Dresden-Rossendorf and Dresden University of Technology have unraveled the water adsorption mechanism in certain microporous materials—so-called hierarchical metal-organic frameworks (MOFs)—while probing the.....»»
Amid new tax rules and VC jitters, hydrogen vehicles still viable
Transportation has largely emerged unscathed from the U.S. Treasury's proposed guidance on hydrogen production tax credits and a leveling off of venture capital deals......»»
After all of this time searching for aliens, are we stuck with the zoo hypothesis?
In 1950, during a lunchtime conversation with colleagues at the Los Alamos National Laboratory, famed physicist Enrico Fermi asked the question that launched a hundred (or more) proposed resolutions. "Where is Everybody?".....»»
Apple again opposes proposed UK surveillance powers, through trade body
Apple last year described proposed new UK surveillance powers as “a serious and direct threat to data security and information privacy” – and it has repeated its opposition to the proposed legal changes, though the techUK trade body. The tec.....»»
New crystalline sponge method proposed for undergraduate courses
The crystal sponge technology is a revolutionary technique, which enables the direct and precise determination of the molecular structure of liquid and gas targets. The technique uses a special network complex to selectively absorb liquid or gas targ.....»»
New strategy for high-performance cathodes in aqueous zinc ion batteries
A new strategy was proposed in the field of aqueous zinc-ion battery to help increase the capacity of the cathodes, making them more efficient, according to a recent study published in ACS Nano......»»
Researchers reveal anthropogenically-induced atmospheric lead cycle in low-latitude Asia
In recent decades, environmental lead (Pb) pollution has posed a significant threat to public health and ecological systems due to its harmful and irreversible effects. It has also been proposed that the distinct Pb pollution signals in geological ar.....»»
Enhancing coastal cities" flood resilience through smart city technologies
Over the rest of this century due to global warming, coastal populations are likely to face increased risk of flooding. A team of researchers has proposed how the integration of Internet of Things, 5G mobile telephony, big data and machine learning i.....»»
Battling persistence in tuberculosis bacteria
Researchers at the Indian Institute of Science (IISc), in collaboration with NCBS and InStem, have uncovered an important mechanism that allows the tuberculosis (TB) bacterium to persist in the human host for decades. They found that a single gene in.....»»
Why the universe might be a hologram
A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional boundary. This corresponde.....»»
Proposed U.S. hydrogen subsidy worth billions would include strict environmental safeguards
