A close galactic pair

Posted by in category: space

This image displays the galaxies NGC 4302 — seen edge-on — and NGC 4298, both located 55 million light-years away. They were observed by Hubble to celebrate its 27th year in orbit.

The galaxy NGC 4298 is seen almost face-on, allowing us to see its spiral arms and the blue patches of ongoing star formation and young stars. In the edge-on disc of NGC 4302 huge swathes of dust are responsible for the mottled brown patterns, but a burst of blue to the left side of the galaxy indicates a region of extremely vigorous star formation.

The image is a mosaic of four separate captures from Hubble, taken between 2 and 22 January 2017, that have been stitched together to give this amazing field of view. Two different types of light emitted by the galaxies — visible and near-infrared — have been combined to give a rich and colourful image. This light was captured by Hubble’s Wide Field Camera 3, one of the telescope’s most advanced imaging instruments.

Mini Brains Just Got Creepier—They’re Growing Their Own Veins

Posted by in categories: biotech/medical, neuroscience

The first human brain balls—aka cortical spheroids, aka neural organoids—agglomerated into existence just a few short years ago. In the beginning, they were almost comically crude: just stem cells, chemically coerced into proto-neurons and then swirled into blobs in a salty-sweet bath. But still, they were useful for studying some of the most dramatic brain disorders, like the microcephaly caused by the Zika virus.

Then they started growing up. The simple spheres matured into 3D structures, fusing with other types of brain balls and sparking with electricity. The more like real brains they became, the more useful they were for studying complex behaviors and neurological diseases beyond the reach of animal models. And now, in their most human act yet, they’re starting to bleed.

Neural organoids don’t yet, even remotely, resemble adult brains; developmentally, they’re just pushing second trimester tissue organization. But the way Ben Waldau sees it, brain balls might be the best chance his stroke patients have at making a full recovery—and a homegrown blood supply is a big step toward that far-off goal. A blood supply carries oxygen and nutrients, allowing brain balls to grow bigger, complex networks of tissues, those that a doctor could someday use to shore up malfunctioning neurons.

Activating Natural Killer T cells to Combat Cancer

Posted by in category: biotech/medical

New research has identified the mechanisms responsible for enhancing immune system activity, offering new approaches for more effective cancer treatments and vaccines.

Invariant natural killer T (iNKT) cells are part of the immune system’s arsenal for fighting infection and defeating diseases like cancer. Finding ways to activate these potent cells more quickly could lead to more effective solutions to cancer and other diseases.

Path to a booming Australian solar thermal energy market

Posted by in categories: solar power, sustainability

A report out from the Australian Renewable Energy Agency (ARENA) this month published responses from industry stakeholders on the viability of a concentrated solar thermal (CST) energy market in Australia: Paving the way for concentrated solar thermal in Australia.

Only 5 gigawatts (GW) of CST is deployed globally so far, with remarkable cost reductions for a technology so “young.” Submissions noted that when today’s 300 GW of PV had only 5 GW of deployed capacity in 2004, its LCOE was ten times that of CST.

CST’s dispatchable solar could play a pivotal role in Australia with its need for that can meet obligations for both emissions reductions and reliability, because with its ability to store its solar energy in molten salts for delivery later, CST can offer a stable and predictable supply of solar energy at any time of day or night.

Oil to solar: Saudis push to be renewable energy powerhouse

Posted by in categories: government, solar power, sustainability

Saudi engineers whip up a simulated sandstorm to test a solar panel’s durability at a research lab, the heart of the oil-rich kingdom’s multibillion dollar quest to be a renewable energy powerhouse.

The world’s top exporter of crude seems an unlikely champion of clean energy, but the government lab in Al Uyayna, a sun-drenched village near Riyadh, is leading the country’s efforts for as it seeks to diversify.

A dazzling spotlight was shone on those ambitions last week when Crown Prince Mohammed bin Salman unveiled plans to develop the globe’s biggest solar project for $200 billion in partnership with Japan’s SoftBank group.
