Research published in the journal Anatomical Record finds that humans have more in common with endangered crocodiles than we think—namely, a deviated septum.
Astrophysicists have made a breakthrough discovery in our understanding of the cosmic forces that shape the heliosphere.
For decades, scientists have hotly debated the origin of the western honey bee. Now, new research has discovered these popular honey-producing bees most likely originated in Asia.
A small clinical trial has found that eating during the nighttime -- like many shift workers do -- can increase glucose levels, while eating only during the daytime might prevent the higher glucose levels now linked with a nocturnal work life.
Pound for pound, the brain consumes vastly more energy than other organs, and, puzzlingly, it remains a fuel-guzzler even when its neurons are not firing signals called neurotransmitters to each other. Now researchers have found that the process of packaging neurotransmitters may be responsible for this energy drain.
Researchers designed a new nanoparticle adjuvant that may be more potent than others now in use. Studies in mice showed it significantly improved antibody production following vaccination against HIV, diphtheria and influenza.
Our understanding of how microscopic structure and changes in the shape of food affect food texture remains underdeveloped, so researchers from Denmark and Germany conducted a series of experiments relating food microstructure and rheology to texture. They used coherent anti-Stokes Raman scattering microscopy to relate the molecular makeup of the fat in foods with the rheological and mechanical...

Photons are the basis for many next-generation quantum technologies, including ultra-secure quantum communications and potentially game-changing quantum computers.
Food texture can make the difference between passing on a plate and love at first bite. To date, most studies on food texture center on relating a food's overall composition to its mechanical properties. Our understanding of how microscopic structure and changes in the shape of food affect food texture, however, remains underdeveloped.

For decades, scientists have hotly debated the origin of the western honey bee. Now, new research led by York University has discovered these popular honey-producing bees most likely originated in Asia.
A multi-institutional team of astrophysicists headquartered at Boston University, led by BU astrophysicist Merav Opher, has made a breakthrough discovery in our understanding of the cosmic forces that shape the protective bubble surrounding our solar system—a bubble that shelters life on Earth and is known by space researchers as the heliosphere.
Few developments have rocked the biotechnology world or generated as much buzz as the discovery of CRISPR-Cas systems, a breakthrough in gene editing recognized in 2020 with a Nobel Prize. But these systems that naturally occur in bacteria are limited because they can make only small tweaks to genes. In recent years, scientists discovered a different system in bacteria that might lead to even more...
Three-dimensional fault models are generally more accurate than two-dimensional line models at sending ground shaking alerts to the correct areas as part of an earthquake early warning system, according to a new study.
Unusual ways of investment, such as collecting toys, can generate high returns. For example, secondary market prices of retired LEGO sets grow by 11% annually, which is faster than gold, stocks, and bonds, HSE University economists say. Their paper was published in the Research in International Business and Finance journal.
Researchers have shown that green tea can be used as a reducing reagent for the preparation of nanomaterials to synthesize ammonia. Compared with bulk graphitic carbon nitride, the optimal sample had 2.93-fold photocatalytic nitrate reduction to ammonia activity (2.627 mg/h/gcat), and the NH3 selectivity increased from 50.77% to 77.9%. The team published their approach on September 06 in Energy...
Robots are already in space. From landers on the moon to rovers on Mars and more, robots are the perfect candidates for space exploration: they can bear extreme environments while consistently repeating the same tasks in exactly the same way without tiring. Like robots on Earth, they can accomplish both dangerous and mundane jobs, from space walks to polishing a spacecraft's surface. With space...
Researchers have developed an approach to print skin equivalents, which may play a future role in facilitating the healing of chronic wounds. They used suspended layer additive manufacturing, creating a gel-like material to support the skin equivalent that can then support a second phase of gel injection. During printing, the skin layers are deposited within the support gel. After printing, the...
