Could biological systems have evolved to find the optimal quantum solutions to the problems thrown at them by nature? This Review presents an overview of the possible quantum effects seen in photosynthesis, avian magnetoreception and several other biological systems.

Donations aren’t enough to sate the world’s need for red blood cells. So a UK firm is working to grow them in a lab.

We’d pictured the plant-fruit relationship as one-way, but new research reports that sometimes the fruit can talk back! And while cow burps are a widely cited contributor to climate change, it turns out that wild pigs might also be contributing with their eating habits.

Mount Sinai researchers have developed a therapeutic agent that shows high effectiveness in vitro at disrupting a biological pathway that helps cancer survive, according to a paper published in Cancer Discovery, a journal of the American Association for Cancer Research, in July.

The therapy is an engineered molecule, named MS21, that causes the degradation of AKT, an enzyme that is overly active in many cancers. This study laid out evidence that pharmacological degradation of AKT is a viable treatment for cancers with mutations in certain genes.

AKT is a cancer gene that encodes an enzyme that is frequently abnormally activated in cancer cells to stimulate tumor growth. Degradation of AKT reverses these processes and inhibits tumor growth.

In the language of Morse code, the letter “S” is three short sounds and the letter “O” is three longer sounds. Put them together in the right order and you have a cry for help: S.O.S. Now an NIH-funded team of researchers has cracked a comparable code that specialized immune cells called macrophages use to signal and respond to a threat.

In fact, by “listening in” on thousands of macrophages over time, one by one, the researchers have identified not just a lone distress signal, or “word,” but a vocabulary of six words. Their studies show that macrophages use these six words at different times to launch an appropriate response. What’s more, they have evidence that autoimmune conditions can arise when immune cells misuse certain words in this vocabulary. This bad communication can cause them incorrectly to attack substances produced by the immune system itself as if they were a foreign invaders.

The findings, published recently in the journal Immunity, come from a University of California, Los Angeles (UCLA) team led by Alexander Hoffmann and Adewunmi Adelaja. As an example of this language of immunity, the video above shows in both frames many immune macrophages (blue and red). You may need to watch the video four times to see what’s happening (I did). Each time you run the video, focus on one of the highlighted cells (outlined in white or green), and note how its nuclear signal intensity varies over time. That signal intensity is plotted in the rectangular box at the bottom.

(NEXSTAR) — An asteroid about the size of a stadium — or three times the size of the Taj Mahal — is set to speed past Earth on Saturday.

The asteroid, called “2008Go20,” is hurtling towards Earth at 18000 mph, according to NASA. Nevertheless, the agency says there’s no reason to worry.

A microchip in your lettuce? Why not, says Arm.

Chip designer Arm has unveiled the most complex flexible microchip yet. The PlasticARM is inefficient and slow compared to silicon-based chips, but could be printed onto fabric, paper, and plastic, allowing for what Arm calls the “internet of everything.”

DeepMind is using its AI prowess to accelerate scientific work.

AI research lab DeepMind has created the most comprehensive map of human proteins to date using artificial intelligence. The company, a subsidiary of Google-parent Alphabet, is releasing the data for free, with some scientists comparing the potential impact of the work to that of the Human Genome Project, an international effort to map every human gene.

Proteins are long, complex molecules that perform numerous tasks in the body, from building tissue to fighting disease. Their purpose is dictated by their structure, which folds like origami into complex and irregular shapes. Understanding how a protein folds helps explain its function, which in turn helps scientists with a range of tasks — from pursuing fundamental research on how the body works, to designing new medicines and treatments.

NASA’s Juno spacecraft is “listening” in on radio emissions from Jupiter’s volcanic moon Io, allowing researchers to discover what triggers the strange radio waves.

Of all the planets in our solar system, Jupiter has the largest and most powerful magnetic field, which extends so far that some of the planet’s moons orbit within it. Because Io is closest to the planet, the moon is “caught in a gravitational tug-of-war” between Jupiter and two other large moons, according to NASA. These opposing pulls cause massive internal heat, which has led to hundreds of volcanic eruptions across the moon’s surface.
