Researchers from the international Past Global Changes (PAGES) project write in the journal Nature Geoscience that they have identified an unprecedented, long-lasting cooling in the northern hemisphere 1500 years ago. The drop in temperature immediately followed three large volcanic eruptions in quick succession in the years 536, 540 and 547 AD. Volcanoes can cause climate cooling by ejecting large volumes of small particles – sulfate aerosols – that enter the atmosphere blocking sunlight.
Huge sea-level rises caused by climate change will last far longer than the entire history of human civilisation to date, according to new research, unless the brief window of opportunity of the next few decades is used to cut carbon emissions drastically.
In a new study, scientists have proposed that tiny residual effects measured by ether-drift experiments in the 1920s and ’30s may be the first evidence of a temperature gradient that was theorized in the 1970s, but never before detected in a laboratory. The theorized temperature gradient is thought to be caused by the solar system moving at 370 km/sec through the cosmic background radiation (CBR), which is the faint electromagnetic radiation that fills the universe.
Just last week, we reported that Germany’s revolutionary nuclear fusion machine managed to heat hydrogen gas to 80 million degrees Celsius, and sustain a cloud of hydrogen plasma for a quarter of a second. This was a huge milestone in the decades-long pursuit of controlled nuclear fusion, because if we can produce and hold onto hydrogen plasma for a certain period, we can harness the clean, practically limitless energy that fuels our Sun.
Engineers from Drexel University have devised a bacteria-powered microrobot that can be steered through fluids with applied electric fields. Imagine a tiny, tiny robotic system covered over by even tinier biomolecular arms (flagella) working cooperatively as a “bacterial surface” to move the biobot from place to place, and then, just as importantly, imagine an algorithm that can steer the thing.
The sight of a cockroach on the run may strike fear into your heart, but what if it were running to save you? That’s what researchers at UC Berkeley had in mind when they designed CRAM, a robot prototype that looks just like a cockroach. CRAM (“compressible robot with articulated mechanisms”) has a jointed exoskeleton and a soft shell that allow it to shape shift and move through small spaces. The researchers think CRAM, whose existence was partially funded by the US Army, could be the first step in creating an incredibly effective search-and-rescue robot.
Australian scientists hope that a tiny device just 3cm long and a few millimetres wide will enable paralysed patients to walk again by allowing them to control bionic limbs with the power of subconscious thought.

Timed flashes of light during sleep may be the best way to combat jet lag, a study has found.
Researchers found that exposing volunteers to short “camera flashes” of light as they slept reset their body clocks.
There’s evidence that mindfulness meditation can improve how we age and even fight disease. Yet, little is known about the brain changes behind the effects.
A new study may offer clues. The results suggest this type of meditation lowers levels of interleukin-6, which is involved in inflammation.
For years, retired Maj. David Underwood has noticed that whenever he drove under power lines and around other electromagnetic fields, he would feel a buzz in what remained of his arm. When traveling by car through Texas’ open spaces, the buzz often became more powerful.

Finding safe, new uses for psychoactive drugs, well-known chemical compounds that can alter the mind, is a fashionable occupation for a niche group of tech enthusiasts called biohackers. Biohackers are hobbyists that typically experiment with psychoactive drugs, among other life-enhancing tools, outside of institutional laboratories.

The way your brain works may vary from season to season, a new study suggests.
Researchers found that when people in the study did certain cognitive tasks, the ways that the brain utilizes its resources to complete those tasks changed with the seasons.
Archaeological excavations of Viking latrine pits in Denmark have revealed that these populations suffered massive worm infestations. The way that their genes developed to protect their vital organs from disease caused by worms has become the inherited trait which can now lead to lung disease in smokers.
A conspiracy theorist’s YouTube video about how this ancient Greek grave marker depicts a laptop more than 2,000 years before personal computers were even a thing has resurfaced, and went viral over the weekend.
We obviously don’t need to tell you that this definitely is not a laptop, and no, the ancient Greeks didn’t possess the technology to go time travelling in search of a better way to communicate with the Oracle of Delphi – a divine being who acted as the official conduit between man and the gods – but what the hell is it?
The Ministry of Antiquities has addressed the German Embassy in Egypt and other concerned authorities to take necessary action towards banning the German teen, Andrej Ciesielski from entering Egypt for life.
Ciesielski, an adrenaline junkie who engages in “roofing” or “urban exploration” from Munich, scaled the Cheops pyramid at Giza without permission and shot an 8 minute video and photos documenting him climbing the 138.8 metre structure.
CAIRO — Egyptian authorities have arrested three people after they appeared in a video selling stones from the 4,500-year-old Giza Pyramids to undercover journalists.
