A scientist gets to the roots of hair loss in a study published at the end of January, saying baldness is due to metabolic changes and free radical damage – and suggests ways to solve the problem. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Why We Grow Bald

Scientists have identified at least nine mechanisms that underly the aging process, the so-called hallmarks of aging. While there are many factors that contribute to baldness, including hormonal changes, two of these hallmarks have been implicated in age-related hair loss in women in a study published in late January of this year.

Display of a candidate event for a W boson decaying into one muon and one neutrino from proton-proton collisions recorded by ATLAS with LHC stable beams at a collision energy of 7 TeV. (Image: CERN In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe. The reported result gives a value of 80370±19 MeV for th…

And this month, a team of scientists will venture to the long-ice-buried expanse to investigate the mysterious ecosystem that was hidden beneath the Antarctic ice shelf for so long.

The newly exposed seabed stretches across an area of about 2,246 square miles (5,818 square kilometers), according to the British Antarctic Survey (BAS), which is leading the expedition. The scientists consider their journey “urgent,” as they hope to document the system before sunlight begins to change at least the surface layers.

“The calving of [iceberg] A-68 [from the Larsen C Ice Shelf] provides us with a unique opportunity to study marine life as it responds to a dramatic environmental change. It’s important we get there quickly before the undersea environment changes as sunlight enters the water and new species begin to colonize,” Katrin Linse, of the British Antarctic Survey, said in a statement.

Credit: Edwards et al., Nature Geoscience, Feb-2018 Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth’s crust collide. The images reveal features of the fault surface, including long grooves or corrugations, that may determine how the fault will slip in an earthquake. The study, published February 12 in Natu…

With a new, “portable” atomic clock, scientists are measuring not what time it is but changes to time itself.

A University of Texas at Dallas graduate student, his advisor and industry collaborators believe they have addressed a long-standing problem troubling scientists and engineers for more than 35 years: How to prevent the tip of a scanning tunneling microscope from crashing into the surface of a material during imaging or lithography. Details of the group’s solution appeared in the January issue of the journal Review of Scientific Instruments, which is published by the American Institute of Physics. Scanning tunneling microscopes (STMs) operate in an ultra-high vacuum, bringing a fine-tipped p…

The first discovered interstellar visitor to our solar system has had a violent past, which is causing it to tumble around chaotically, a Queen’s University Belfast scientist has discovered.

Using lasers instead of electrodes to vibrate the hairs in the inner ears could lead to less damaging cochlear implants.
