Intel releases 12-qubit silicon quantum chip to the quantum community

The distribution of the quantum chip to the quantum community is part of Intel’s plan to let researchers gain hands-on experience with the technology, while at the same time enabling new quantum research.

Stone walls uncovered along the Nile reveal ancient engineering marvel

An international team of researchers has revealed a groundbreaking discovery along the banks of the River Nile in Egypt and Sudan.

This incredibly long-lived hydraulic technology played a crucial role in enabling communities to grow food and thrive in the challenging landscapes of Nubia for over 3000 years.

Their findings shed light on an extraordinary network of river groynes — stone walls built perpendicular to a river bank intended to break water flow and sediment erosion.

Scientists found evidence of a whole new way for stars to die

An international team of astrophysicists set out to investigate the origins of a powerful gamma-ray burst (GRB) and stumbled upon a long-hypothesized but never-before-observed type of star death.

Most GRBs originate from exploding stars or neutron star mergers, but the newly observed example came from a GRB designated 191019A that formed when stars or stellar remnants in the environment surrounding a supermassive black hole collided near the core of an ancient galaxy.

Synthetic human embryos created for the first time

For the first time, researchers have created synthetic human embryos from stem cells, pushing us into an ethical gray area but offering the promise of important insights into the critical early stages of human development.

The synthetic embryos, which are not the product of natural sexual reproduction but engineered from stem cells in a laboratory setting, could provide medical researchers with critical insights into the first few weeks of embryonic development, during which a host of genetic disorders are thought to manifest.

One step closer to growing naturally decaffeinated coffee beans

Who doesn’t like a cold or a hot cup of joe in the morning? Probably people who have a caffeine sensitivity. But for regular drinkers of bean juice, it can spell the difference between a good day and a bad day.

Decaf iced vanilla latte! Decaf espresso! shout the Starbucks baristas as they take customers’ orders. Because coffee can lead to issues like anxiety and high blood pressure, a lot of people opt for decaffeinated options. Decaffeination removes about 97 percent of the caffeine from the coffee beans and is more expensive to produce than regular coffee, according to data from the National Coffee Association.

New type of computer memory could greatly reduce energy use and improve performance

Researchers have developed a new design for computer memory that could both greatly improve performance and reduce the energy demands of internet and communications technologies, which are predicted to consume nearly a third of global electricity within the next ten years.

The researchers developed a device that processes data in a similar way as the synapses in the human brain. The devices are based on hafnium oxide, a material already used in the semiconductor industry, and tiny self-assembled barriers, which can be raised or lowered to allow electrons to pass.

This method of changing the electrical resistance in computer memory devices, and allowing information processing and memory to exist in the same place, could lead to the development of computer memory devices with far greater density, higher performance and lower energy consumption.

World's first astronaut with disability to begin training

Former UK Paralympian John McFall, a surgeon for the UK's NHS public health service, was selected by the European Space Agency (ESA) last year when it announced its new class of astronauts.

Shortly after his selection last year, McFall stated, "The message I would give to future generations is that science is for everyone and space travel hopefully can be for everyone."

He will spend the next two years forming part of a feasibility study carried out by ESA and NASA to assess the conditions required for people with disabilities to go to space.

Ecological 'doom loops' edging closer, study warns

Extreme weather events such as wildfires and droughts will accelerate change in stressed systems leading to quicker tipping points of ecological decline, according to a new study.

Using computer modeling, the U.K. research team, looked at four ecosystems under threat to work out what factors might lead to tipping points, beyond which collapse was inevitable. In some systems, the combination of adding new extreme events on top of other ongoing stresses brought the timing of a predicted tipping point closer to the present by as much as 80%.

Ultimately, say the authors, a "perfect storm" of continuous stress from factors such as unsustainable land use, agricultural expansion and climate change, when coupled with disruptive episodes like floods and fires, will act in concert to rapidly imperil natural systems.

Physicists Discover a New State of Matter Hidden in The Quantum World

You're familiar with the states of matter we encounter daily – such as solid, liquid, and gas – but in more exotic and extreme conditions, new states can appear, and scientists from the US and China just found one.

They're calling it the chiral bose-liquid state, and as with every new arrangement of particles we discover, it can tell us more about the fabric and the mechanisms of the Universe around us – and in particular, at the super-small quantum scale.

Scientists are developing a smart skin for use in robots in space

As robots continue to show up all around the world they also take center stage in space. This requires that the machines work well with their human colleagues and that they are also able to withstand the harshness of space with its radiation, low pressure, and violent temperature fluctuations.

“We will design and test a smart skin that will make robots more suitable for future space exploration. It involves testing advanced surface sensors and alarm panels that can enable the robots to detect and avoid potential collisions with objects in the environment. This will make them robust and safe helpers for astronauts in space."

Space travel can alter gene expression in white blood cells, weakening our immune system

Evidence is mounting that astronauts are more susceptible to infections while in space. For example, astronauts on board the International Space Station (ISS) commonly suffer from skin rashes, as well as respiratory and non-respiratory diseases. Astronauts are also known to shed more live virus particles; for example, the Epstein-Barr virus, varicella-zoster responsible for shingles, herpes-simplex-1 responsible for sores, and cytomegalovirus. These observations suggest that our immune system might be weakened by space travel. But what could cause such an immune deficit?

"Here we show that the expression of many genes related to immune functions rapidly decreases when astronauts reach space, while the opposite happens when they return to Earth after six months aboard the ISS..."

The next big advance in cancer treatment could be a vaccine

After decades of limited success, scientists say research has reached a turning point.

These aren't traditional vaccines that prevent disease, but shots to shrink tumors and stop cancer from coming back. Targets for these experimental treatments include breast and lung cancer, with gains reported this year for deadly skin cancer melanoma and pancreatic cancer.

"We're getting something to work. Now we need to get it to work better," said Dr. James Gulley.

More than ever, scientists understand how cancer hides from the body's immune system. Cancer vaccines, like other immunotherapies, boost the immune system to find and kill cancer cells. And some new ones use mRNA, which was developed for cancer but first used for COVID-19 vaccines.
