Ordinarily, if you’re building something, you don’t want the materials to buckle under pressure. In a new Harvard University-designed system, however, that buckling action allows flat-packed objects to be twisted into useful three-dimensional forms.
Most existing “buckling-induced deployable structures” consist of linked straight pieces that are popped into shape via straight linear motion, which often requires a fair bit of force to be applied by the user. Folding chairs are one frequently frustrating example.
Seeking an easier alternative, Harvard researchers instead set about building items made up of linked curved pieces. Generally speaking, curved objects (such as beams) are less mechanically stable than their straight counterparts. In most scenarios, this is an undesirable quality. In the case of pop-up devices, though, it means that they’re easier to buckle into the desired form.
“In physics, we often say that exceptional discoveries require exceptionally strong evidence.”
Within the space of ten days, LIGO detected gravitational waves that prove black holes can form binaries with neutron stars.

Almost all the lawsuits draw on the oil industry’s own records as the foundation for claims that it covered up the growing threat to life caused by its products.
Shell, like other oil companies, had decades to prepare for those consequences after it was forewarned by its own research. In 1958, one of its executives, Charles Jones, presented a paper to the industry’s trade group, the American Petroleum Institute (API), warning about increased carbon emissions from car exhaust. Other research followed through the 1960s, leading a White House advisory committee to express concern at measurable and perhaps marked changes in climate by 2000.
With an unprecedented wave of lawsuits, America’s petroleum giants face a reckoning for the environmental devastation caused by fossil fuels – and covering up what they knew along the way.
Bacterial infections of the middle ear are quite common, particularly in children, yet they can be difficult to treat. An experimental new device has been designed to help, by zapping the bacteria with plasma.
Usually, such infections are treated with topically applied antibiotics. According to the University of Illinois at Urbana-Champaign, however, such an approach is ineffective in over 30 percent of acute infections. This is because the antibiotics have trouble penetrating the bacterial biofilm that has formed on the surface of the inner ear tissue.
Additionally, the greater the amount of antibiotics that are used, the greater the chances that the bacteria will develop a tolerance to them over time. With these limitations in mind, U Illinois scientists set out to develop an alternative treatment, or at least one that would allow smaller amounts of antibiotics to be more effective.
CI Annual General Meeting 2021

Sun, Sep 12 at 12 PM PDT.
This is an invitation to the Annual General Meeting of the Cryonics Institute & the Immortalist Society.
The Cryonics Institute, Annual General Meeting (AGM) will be held at 3:00pm to 6:30pm on Sunday, September 12th, 2021 at the Infinity Hall 16650 E. 14 Mile Rd, Fraser, MI 48026 (USA) for more information visit www.infinityhallsidebar.com or call 586−879−6157. Tours at the CI facility will be from 1:00pm to 2:30pm 24355 Sorrentino Court, Clinton Township, (Michigan) 48035 (USA).
The AGM of the Immortalist Society will be held after the CI AGM on the same day at the same location. The two meetings generally last most of the afternoon. A buffet dinner & social follow. The CI facility will be open to guests and visitors two hours before the meeting begins.
Virgin Orbit launched seven satellites today (June 30), taking a big step toward regular and reliable commercial launch service.
Not sure how interesting this will be to people who know a lot on aging/longevity research.
A team of researchers at Brigham and Women’s Hospital and Harvard Medical School have found evidence of mouse and human germline cells resetting their biological age. In their paper published in the journal Science Advances, the group describes their study of the aging process in germline cells and what they found by doing so.
As animals grow older, all of the cells in their body replicate themselves repeatedly. As the process continues, errors in replicating and other external factors (such as exposure to pollutants) lead to gradual decay in cell quality, which is all part of the natural aging process. In this new effort, the researchers have found evidence showing that germline cells have a mechanism for resetting this process, allowing offspring to reset their aging clocks.
Germline cells pass on genetic material from parent to offspring during the reproductive process. For many years, scientists have wondered why these cells do not inherit the age of their parents. And for many years, they assumed that the cells were ageless, but recent work has shown that they do, in fact, age. So that raised the question of how offspring are able to begin their lives with fresh cells.
