A gene linked to Alzheimer's Disease may impact cognitive health much sooner than previously realized.
The APOE gene creates a protein, apolipoprotein E, which packages cholesterol and other fats to transport them through the bloodstream. There are three versions, or alleles, of APOE. One of those is the APOE4 allele, present in about 15 percent of the population. APOE4 carriers are up to three times more likely to develop late-onset Alzheimer's disease, which occurs in people 65 and older.
Inventors of centuries past and scientists of today have found ingenious ways to make our lives better with magnets - from the magnetic needle on a compass to magnetic data storage devices and even MRI (magnetic resonance imaging) body scan machines.
AMHERST, Mass. - Conventional magnets are hard and rigid but have made great contributions to society and to modern industry, says materials scientist Thomas Russell of the University of Massachusetts Amherst. But this award-winning innovator dreamed of more - what if magnets could be soft, flowable as liquid and malleable to conform to a limited space?
Our highly mobile mammalian tongues, which allow us to swallow chewed food and suckle milk as babies, may have evolutionary origins in some of our most early mammalioform ancestors, according to a new study, which finds remarkably complex and modern mammal-like hyoid bones in a newly discovered 165-million-year-old mammaliaform species.
Chemical manufacturers consume a massive amount of energy each year separating and refining feedstocks to make a wide variety of products including gasoline, plastics and food.
In a bid to reduce the amount of energy used in chemical separations, researchers at the Georgia Institute of Technology are working on membranes that could separate chemicals without using energy-intensive distillation processes.
The molten rock that feeds volcanoes can be stored in the Earth's crust for as long as a thousand years, a result which may help with volcanic hazard management and better forecasting of when eruptions might occur.
Researchers from the University of Cambridge used volcanic minerals known as 'crystal clocks' to calculate how long magma can be stored in the deepest parts of volcanic systems. This is the first estimate of magma storage times near the boundary of the Earth's crust and the mantle, called the Moho. The results are reported in the journal Science.
Diversity on teams leads to positive outcomes for participants, but not those doing the diversifying
ANN ARBOR--Individuals on teams of diverse people working together can have better outcomes than those on teams with similar individuals, research as shown.
But a new study by University of Michigan and Michigan State University researchers found that the very individuals who add diversity to their science teams surprisingly do not experience positive outcomes.
Has your steering wheel been too hot to touch this summer? A new thermoelectric material reported in the journal Science could offer relief.
The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature.
A computational simulation suggests that insects may be capable of using the properties of light from the sky to determine their compass direction with an error of less than two degrees. Evripidis Gkanias of the University of Edinburgh, U.K., and colleagues present their findings in PLOS Computational Biology.

NASA's Aqua satellite found Tropical Storm Danas moving over Japan's Ryuku island chain in the Northwestern Pacific Ocean.
The Ruyku islands include Osumi, Tokara, Amami, Okinawa, Yonaguni and the Sakishima Islands. The island chain extends southwest from Kyushu to Taiwan.
PROVIDENCE, R.I. [Brown University] -- By measuring the fast electrical spikes of individual neurons in the touch region of the brain, Brown University neuroscientists have discovered a new type of cell that keeps time so regularly that it may serve as the brain's long-hypothesized clock or metronome.
Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR).
Low doses of radiation equivalent to three CT scans, which are considered safe, give cancer-capable cells a competitive advantage over normal cells in healthy tissue, scientists have discovered. Researchers at the Wellcome Sanger Institute and the University of Cambridge studied the effects of low doses of radiation in the oesophagus of mice.
The risk factors for stroke and dementia are the same, and a growing body of evidence demonstrates that preventing stroke can also prevent some dementias.
Now, a group of experts led by Western University Professor, Dr. Vladimir Hachinski and international collaborators Matthias Endres, Martin Dichgans and Zaven Khachaturian are calling on the global community to come together to take action on preventing dementia by preventing stroke.
