Science X Newsletter Week 06

Dear Reader ,

Here is your customized Science X Newsletter for week 06:

Capsule that releases insulin in the stomach could replace injections for patients with type 2 diabetes

An MIT-led research team has developed a drug capsule that could be used to deliver oral doses of insulin, potentially replacing the injections that people with type 2 diabetes have to give themselves every day.

Scientists discover new type of magnet

A team of scientists has discovered the first robust example of a new type of magnet—one that holds promise for enhancing the performance of data storage technologies.

Culprit found for honeybee deaths in California almond groves

It's about time for the annual mass migration of honeybees to California, and new research is helping lower the chances the pollinators and their offspring will die while they're visiting the West Coast.

Check your compass: The magnetic north pole is on the move (Update)

North isn't quite where it used to be.

Traffic fatalities on a high after cannabis legalisation

Monash University research examined the effect of recreational cannabis sales (RCS) on traffic fatalities in three US states where it was legalised—Colorado (legalised 2014), Washington (2014), and Oregon (2015), and nine neighbouring jurisdictions from 2009-2016.

New scan technique reveals brain inflammation associated with post-treatment Lyme disease syndrome

More than 1 in 10 people successfully treated with antibiotics for Lyme disease go on to develop chronic, sometimes debilitating, and poorly understood symptoms of fatigue and brain fog that may last for years after their initial infection has cleared up. Now, in a small study, Johns Hopkins Medicine researchers report they have used an advanced form of brain scan to show that 12 people with documented post-treatment Lyme disease syndrome (PTLDS) all show elevation of a chemical marker of widespread brain inflammation, compared with 19 healthy controls.

Breakthrough device lures aggressive brain tumor cells out of the patient

A biomedical tool that tricks aggressive brain tumors such as glioblastoma into migrating into an external container rather than throughout the brain has been designated a "Breakthrough Device" by the U.S. Food and Drug Administration (FDA).

The Milky Way is warped

The Milky Way galaxy's disk of stars is anything but stable and flat. Instead, it becomes increasingly warped and twisted far away from the Milky Way's center, according to astronomers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC).

Scientists develop first fabric to automatically cool or insulate depending on conditions

Despite decades of innovation in fabrics with high-tech thermal properties that keep marathon runners cool or alpine hikers warm, there has never been a material that changes its insulating properties in response to the environment. Until now.

Dying bacteria absorb antibiotic, allowing others to survive and grow

Bacteria have multiple strategies to survive antibiotics: developing genetic resistance to the drugs; delaying their growth; or hiding in protective biofilms. New results from researchers at Princeton and California State University-Northridge (CSUN) have shed light on yet another approach: self-sacrifice.

Dinosaur that defended itself with spiny backbone found in Patagonia

A herbivorous dinosaur that fended off predators with a row of spines running along its back and lived 140 million years ago has been found in Argentine Patagonia.

Richard Branson says he'll fly to space by July

British billionaire Richard Branson plans to travel to space within the next four or five months aboard his own Virgin Galactic spaceship, he told AFP Thursday.

When a generation loves a previous musical era: Millennials' recognition of 1960s-1990s songs is notable

Millennials' recognition of songs from the 1960s through the 1990s is relatively stable over this 40-year period, a team of researchers has found. By contrast, their recognition of musical hits from 2000 to 2015, while higher overall than the previous era, diminishes rapidly over time.

Much of the surface ocean will shift in color by end of 21st century: study

Climate change is causing significant changes to phytoplankton in the world's oceans, and a new MIT study finds that over the coming decades these changes will affect the ocean's color, intensifying its blue regions and its green ones. Satellites should detect these changes in hue, providing early warning of wide-scale changes to marine ecosystems.

Scientists simulate a black hole in a water tank

Certain phenomena that occur in black holes but cannot be directly observed in astronomic investigations can be studied by means of a laboratory simulation. This is possible due to a peculiar analogy between processes that are characteristic of black holes and hydrodynamic processes. The common denominator is the similarity of wave propagation in both cases.

Marijuana smoking linked with higher sperm concentrations, study finds

Men who have smoked marijuana at some point in their life had significantly higher concentrations of sperm when compared with men who have never smoked marijuana, according to new research led by Harvard T.H. Chan School of Public Health. The study, conducted in the Fertility Clinic at Massachusetts General Hospital, also found that there was no significant difference in sperm concentrations between current and former marijuana smokers.

Researchers find evidence for a new fundamental constant of the Sun

New research undertaken at Northumbria University, Newcastle shows that the sun's magnetic waves behave differently than currently believed.

Hubble reveals dynamic atmospheres of Uranus, Neptune

During its routine yearly monitoring of the weather on our solar system's outer planets, NASA's Hubble Space Telescope has uncovered a new mysterious dark storm on Neptune and provided a fresh look at a long-lived storm circling around the north polar region on Uranus.

Researchers unearth an ice age in the African desert

A field trip to Namibia to study volcanic rocks led to an unexpected discovery by West Virginia University geologists Graham Andrews and Sarah Brown.

Scientists identify reversible molecular defect underlying rheumatoid arthritis

In rheumatoid arthritis, immune cells called helper T cells behave differently from their counterparts in healthy cells and in other autoimmune diseases. Stanford scientists have learned why.
