Scientists reveal that Australia's pint-sized banded hare-wallaby is the closest living relative of the giant short-faced kangaroos which roamed the continent for millions of years, but died out about 40,000 years ago.
Materials scientists have found that oscillating loads at certain frequencies can lead to several-fold increases in the strength of composites with an interface that is modified by a molecular layer of 'nanoglue.'
Takayasu arteritis is an autoimmune disease resulting in chronic aortic inflammation leading to aneurysm or aortic regurgitation. Researchers showed that it is caused by MLX gene mutation. This mutation increased oxidative stress and inflammasome formation and activity, specifically in the aortic valves, explaining the inflammatory state and associated symptoms. This insight suggests the potential value of treating this disease with medicines effective against other conditions involving excessive inflammasome activation.
Scientists have developed a way of finding optimal peptide sequences: using a machine-learning algorithm as a collaborator. The algorithm analyzes experimental data and offers suggestions on the next best sequence to try, creating a back-and-forth selection process that reduces time needed to find the optimal peptide. The results could provide a new framework for experiments across materials science and chemistry.
How does cancer spread? While studying human brain tumour cells, a team of scientists found some answers to this crucial, yet so far unanswered question. They looked at a gene called EGFRvIII, which is present in patients with glioblastoma -- a highly aggressive form of brain cancer that spreads quickly and that is difficult to treat.
Researchers have discovered what might be an effective strategy to prevent and combat cognitive dysfunction in obese individuals. They are the first to examine the modulatory role of an exercise-induced protein in the brain that promotes neuron survival and used high-intensity interval exercise (HIIE) in obese and normal-weight subjects. Obesity reduces the expression of this protein and lower levels are associated with Alzheimer's, Parkinson's and obesity. HIIE upregulated this protein in the obese subjects compared to normal-weight subjects.
Researchers have identified in live human brains new radioactive 'tracer' molecules that bind to and 'light up' tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer's disease and other related dementias.
A new image from the NASA/ESA Hubble Space Telescope shows the core and the innermost parts of the spiral arms of a spiral galaxy called Messier 100. Messier 100, also known as M100, NGC 4321 and LEDA 40153, is located approximately 50 million light-years away in the constellation of Coma Berenices. This galaxy is one [...]
Invasive species and habitat loss are the biggest threats to Australian biodiversity, according to new research. Australia was rich in unique biodiversity, but has had a poor track record since European settlement.
You probably overestimate just how far someone can push you before you reach your tipping point, new research suggests. A new study tilted people backwards in a device and asked them at what point they thought they would fall if they weren't supported. Most people would have fallen long before they thought they would.
Compared with skipping a flu shot, getting a flu shot was associated with an 18 percent reduced risk of premature death among newly-diagnosed heart failure patients. Moreover, regular annual flu shots were associated with a 19 percent reduction in both all-cause and cardiovascular death when compared with no vaccination.
On December 1, 2018, NASA’s InSight lander captured a haunting low rumble caused by vibrations from the Martian wind, estimated to be blowing between 10 to 15 mph (5-7 m/sec) from northwest to southeast. The wind was consistent with the direction of dust devil streaks in the landing area, which were observed from orbit. “Capturing [...]
In an analysis of septuagenarians who have been exercising for decades, researchers from Ball State University found that they have heart and lung capacities and muscle fitness like healthy people in their early 40’s. The findings were published in the Journal of Applied Physiology. “Exercise wins is the take-home message. We saw that people who [...]
The kagome ferromagnet Fe3Sn2 exhibits an electronic state that couples unusually strongly to an applied magnetic field that can be rotated to point in any direction of a 3-dimensional space, revealing that magnetization drives -- in quantum scale -- a 'giant' energy shift within the material, an international team of researchers has found.
A new study could help states that will soon expand Medicaid, or may add a work requirement, understand what might be in store. Nearly half of enrollees in Michigan's expanded Medicaid felt their physical health improved; more than a third cited better mental or dental health. Over two-thirds of those with jobs said coverage helped them do better at work; those who said their health had improved were four times as likely to say this.
The future of the US Interstate Highway System is threatened by a persistent and growing backlog of structural and operational deficiencies and by various looming challenges, such as the progress of automated vehicles, developments in electric vehicles, and vulnerabilities due to climate change.
