In a study using brain tissue from deceased human donors, Johns Hopkins Medicine researchers say they found new evidence that schizophrenia can be marked by the buildup of abnormal proteins similar to those found in the brains of people with such neurodegenerative disorders as Alzheimer's or Huntington's diseases.
A large-scale study from The University of Toledo of young African Americans who have attempted or died by suicide suggests there is a greater need for mental health services in urban school districts, and that we need to do a better job in convincing parents and caregivers to safely secure firearms and ammunition in the home.
Taking those measures, Dr. James Price said, could save lives.
Years before symptoms of Alzheimer's disease appear, two kinds of damaging proteins silently collect in the brain: amyloid beta and tau. Clumps of amyloid accumulate first, but tau is particularly noxious. Wherever tangles of the tau protein appear, brain tissue dies, triggering the confusion and memory loss that are hallmarks of Alzheimer's.
Scientists from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences and their collaborators investigated the mechanism of rapid reactivity of the F + H2 reaction at low temperature and found that rapid reactivity was actually induced by resonance-enhanced tunneling.
This finding explains the observation of HF in interstellar clouds, which is generated only through the F + H2 reaction. The research was published in Nature Chemistry.
The project gives valuable new insights on how genetic adjustments through evolution have rendered the ruminants one of the most successful groups of animals on the planet. The results have recently been published in three articles in the acknowledged scientific journal Science.
Approx. 20 million years ago, ruminants began to outmatch all other groups of large herbivores. Today ruminants count more than 200 species from all ecosystems and in all sizes, ranging from 2 to 1500 kg.
A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and older African American research participants.
Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved. Now, researchers have a developed a double-duty hydrogel that both attacks the bacteria and encourages bone regrowth with a single application containing two active components.
Islamic values are just as important as the destination, quality and value for money for Muslims when choosing a holiday destination, according to a new study by the University of Portsmouth.
The research found that when choosing a halal holiday (one that allows Muslim tourists to go on a holiday while remaining true to their religion), Muslim's travel destinations are based on a combination of 'consumption' values (associated with accommodation, airline, entertainment), 'personal' values (fun, enjoyment, security) and Islamic religious values, such as Iman (faith).
An international group of scientists is making major advances in sustaining the world's environments, untangling the intricate ways in which people and nature depend on each other.
The results are published in today's Nature Sustainability and includes contributions from a team of scientists based at the ARC Centre of Excellence for Coral Reef Studies (Coral CoE).
With major crises such as extinctions and environmental degradation now upon us, the timing of the study is crucial.
Dying stars that cast off their outer envelopes to form the beautiful yet enigmatic "planetary nebulae" (PNe) have a new heavy-weight champion, the innocuously named PNe "BMP1613-5406". Massive stars live fast and die young, exploding as powerful supernovae after only a few million years. However, the vast majority of stars, including our own Sun, have much lower mass and may live for many billions of years before going through a short lived but glorious PNe phase. PNe form when only a tiny fraction of unburnt hydrogen remains in the stellar core.
BELLEVUE, WA --The frigid lakeshores of Saturn's moon Titan might be encrusted with strange, unearthly minerals, according to new research being presented here.
Scientists re-creating Titan-esque conditions in their laboratory have discovered new compounds and minerals not found on Earth, including a co-crystal made of solid acetylene and butane.
For the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing 'piece of the puzzle' in our understanding of the formation of structure in the Universe, since large-scale structures--such as galaxies and clusters of galaxies--are thought to grow by collisions and mergers. The result was published in Nature Astronomy.
Many people suffer from a vitamin D deficiency. This can result in brittle bones and an increased risk of respiratory diseases. Chicken eggs are a natural source of vitamin D and one way to, at least partially, compensate for this deficiency. A team of nutritionists and agricultural scientists at Martin Luther University Halle-Wittenberg (MLU) has found a new way to further increase the vitamin D content of eggs: by exposing chickens to UV light. As the team writes in the scientific journal Poultry Science, the method can be put into practice in henhouses straight away.
For the third year in a row, the Trump administration has proposed large cuts in science funding across a variety of agencies. Although Congress restored these cuts in the past two years, increased budgetary pressures may discourage them from doing so this year.
Now, new research from the University of California, Berkeley, the University of Connecticut, Boston University, and Harvard University shows that these cuts in federal funding for science might endanger the innovation that increasingly fuels the modern economy. The study was published recently in Science.
Human screams convey a level of individual identity that may help explain their evolutionary origins, finds a study by scientists at Emory University.
PeerJ published the research, showing that listeners can correctly identify whether pairs of screams were produced by the same person or two different people -- a critical prerequisite to individual recognition.
