COVID variants expands

In 2022, the Omicron variant of that made it harder to predict coming surges. The XBB variant and offshoots in the BQ.1 family have set off fresh waves of infection in parts of the world. The variants have enabled scientists to pinpoint immunity-evading mutations that help the virus

terrible toll

The pandemic continues to take a devastating toll. A study estimated that around a dramatic increase on earlier estimates.

Where’s Webb? Lagrange points explained

When NASA’s James Webb Space Telescope in January, it landed at a special spot called the second Lagrange point, or L2. Here, the gravitational pull of the Sun and Earth equals the centripetal force required for the telescope to move with them. The location is particularly good for sensitive astronomical observatories such as JWST, which is the most complex telescope ever built.

Cost-of-living crisis hits science students

Eighty-five per cent of graduate students were and 25% were concerned about their growing student debt, according to a Nature survey. Forty-five per cent said that rising inflation could cause them to reconsider whether to continue their science studies. The survey involved more than from around the world.

Our trees are vanishing

The A huge tree-hunting exercise called the Global Tree Assessment revealed that 29.9% of species are threatened. Some 142 species are thought to be extinct in the wild.
How to crash into an asteroid
On 26 September, NASA successfully 11 million kilometres from Earth. The aim was to speed up Dimorphos’s orbit — and to test whether it would be possible to if it was heading for Earth.
Which fish to eat

Researchers identified which species of seafood are than eating meat. These include farmed bivalves — shellfish such as mussels, clams and oysters — as well as wild-caught salmon and small surface-dwelling (pelagic) fish such as anchovies, mackerel and herring.

Your growing, shrinking brain

Researchers created the showing how brains expand quickly early in life and then shrink slowly with age. The sheer magnitude of the study, which involved a vast set of magnetic resonance imaging (MRI) scans, stunned neuroscientists.
Looming spillovers

The because of environmental damage. This chart shows the viral diseases that have spilled over from animals to humans since 1918, and how many people were killed by the resulting outbreaks. Spillover events have probably triggered every viral pandemic that’s occurred since the start of the twentieth century.

And finally: how artificial hairs keep beat

Scientists in response to light. They mimic cilia, the microscopic hairs that propel some single-celled creatures through fluid by beating rhythmically.

The tiny machines are incorporated into a liquid-crystalline polymer material (a). Light makes the machines change shape, deforming the illuminated area, and cause the cilium to bend and twist (the wobbly skyscrapers in the graphic). As soon as one cilium starts beating, light shines on the neigh cilium, which, in turn, starts moving (b). This creates a domino effect of movement through the array.
