Scientists Implanted Tiny Human Brains Into Mice

Posted by in categories: biotech/medical, neuroscience

The mice helped the tiny organoids get nutrients, oxygen, and even start developing human neurons.

Scientists at the Salk Institute implanted lentil-sized human brain organoids into the heads of mice, then closed it with a transparent window. The mice looked and behaved like ordinary mice, while supplying blood and nutrients to keep human brains developing for months.

Newt Gingrich: A glimpse of America’s future in space in 2024

Posted by in categories: innovation, space travel

Two historic events happened this past week that will lay the groundwork for the future of American space exploration.

First, after a close vote in the Senate, Rep. Jim Bridenstine, R-Okla. – a former Navy combat pilot – was confirmed as the new head of NASA. I am confident he will be a strong leader in space exploration as we begin a new era of innovation, technological advancement and limitless exploration.

Second, Vice President Mike Pence laid out a bold vision for America’s future in space exploration during his opening remarks at the Space Foundation’s 34th Annual Space Symposium in Colorado. The vice president showed the Trump administration’s commitment to restoring American leadership in space, rightly pointing out that “we stand at the dawn of a new era of human activity in space; a turning point that will bring new opportunities and new challenges.”

Natural Causes

“Old age isn’t a battle,” she says, quoting Philip Roth, “old age is a massacre.” In the past few years, she has given up on screenings and scans. Not that she is lazy or suicidal. But at 76, she considers herself old enough to die. All the self-help books aimed at her age group tell her otherwise; they talk of “active ageing”, “productive ageing”, “anti-ageing”, even “reverse-ageing”, with a long life promised to anyone who makes an effort, regardless of factors such as genetics or poverty. But to her, ageing is “an accumulation of disabilities”, which no amount of physical activity or rigorous self-denial can prevent. If she has symptoms, she’ll have them investigated. But when a doctor tells her there could be an undetected problem of some kind, she won’t play along.


A great iconoclast has written a polemic about ageing that sends up New Age platitudes and is full of scepticism of the wellness industry.

Did You Know the Earth Has a Second Magnetic Field? Its Oceans

Posted by in category: climatology

Beyond this, another aim of the mission is to increase our knowledge of atmospheric processes and ocean circulation patterns that affect climate and weather. The ocean is also an important subject of study to the Swarm mission because of the small ways in which it contributes to Earth’s magnetic field. Basically, as the ocean’s salty water flows through Earth’s magnetic field, it generates an electric current that induces a magnetic signal.

Because this field is so small, it is extremely difficult to measure. However, the Swarm mission has managed to do just that in remarkable detail. These results, which were presented at the EGU 2018 meeting, were turned into an animation (shown below), which shows how the tidal magnetic signal changes over a 24 hour period.

As you can see, the animation shows temperature changes in the Earth’s oceans over the course of the day, shifting from north to south and ranging from deeper depths to shallower, coastal regions. These changes have a minute effect on Earth’s magnetic field, ranging from 2.5 to −2.5 microtesla. As Nils Olsen, from the Technical University of Denmark, explained in a ESA press release:

Radar Mapping of Mercury: Full-Disk Images and Polar Anomalies

Posted by in categories: mapping, space

A random-code technique has been used at Arecibo to obtain delay-Doppler radar images of the full disk of Mercury. Anomalously bright features were found at the north and south poles. The north polar feature is oblong (4° by 8°) and offset from the pole. The smaller south polar feature is mostly confined to the floor of the crater Chao Meng-Fu. The polar locations and radar properties of these features indicate that they may be produced by volume scattering in ice. The images also reveal a variety of more subdued reflectivity features ranging in size from hundreds to thousands of kilometers; some of these appear to have an impact origin.

Neurosurgeon Eric Leuthardt: ‘An interface between mind and machine will happen’

Posted by in categories: biotech/medical, employment, robotics/AI

I guess any procedure involving the brain feels like a different category of risk to most people. You must face that anxiety every day. I think there are two types of surgical practice that really strike at the core of people’s anxiety. One is brain surgery, where you are operating on something that people see as themselves, their sense of identity, their mind. The other one is, I think, paediatric surgery, where the operation is on the thing most precious to you – your children. I think both create a dynamic where you need to work harder to create trust with your patients.

When it comes to innovation that might link a person’s mind directly with a machine, it seems as much an ethical as a medical question. Is that how you see it? Ethicists are critical in what we do. A working interface would be a real turning point in human evolution. I don’t say that with bombast or hyperbole. And just like with artificial intelligence, we need to take the greatest care in how we think about it. Whether it happens in five years or 50 years, it will happen. I wrote these two science-fiction novels to try to walk people through some of the things that could happen; for example, if others got unauthorised access to these implants, or when corporations got involved. We need to be thinking about these things now, rather than after the fact.

Was one of the motivations in writing your books to work out these things for yourself? Did you feel the same at the beginning of the process as at the end? I had certain ideas in mind when I started the books, but there was an evolution. I came to think less about that individual interface and more about the effect this technology might have on society. We need to think hard about how advances [might] not increase social division.

‘Interplanetary Shock Wave’ Spawns Electric-Blue Auroras

Posted by in categories: particle physics, space

A moderate geomagnetic storm kicked up in Earth’s skies Friday morning (April 20), bringing green and rare electric-blue auroras that stretched as far south as Indiana.

The space-weather news site Spaceweather.com reported that an “interplanetary shock wave” hit Earth’s magnetic field at about 3:50 a.m. EDT (2350 on April 19 GMT), quadrupling the intensity of the flow of particles streaming from the sun toward Earth, called the solar wind. The incoming wave of material resulted in a G2-level, or moderate, geomagnetic storm, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC). These types of storms can cause power grid fluctuations and have some impact on radio communications. [See Spectacular Photos of Auroras from Space]

And they also cause enhanced auroras. This storm led to auroras possibly reaching through Canada and as far south as New York, Wisconsin and Washington state in the U.S., the SWPC said.
