Ships releasing alkalinizing agents could buy time for Great Barrier Reef

The increasing buildup of carbon dioxide in the atmosphere is reshaping the environment in many ways beyond the ongoing rise of global temperatures. Some major ones relate to the ocean, which is becoming not just warmer but also more acidic, threatenin… Continue reading Ships releasing alkalinizing agents could buy time for Great Barrier Reef

Experimental drug prevents dangerous brain tangles following concussion

The repeated concussions experienced by athletes in contact sports can have grave consequences later in life, increasing chances of developing a range of neurodegenerative diseases. A new study has explored the connections between these brain injuries … Continue reading Experimental drug prevents dangerous brain tangles following concussion

New instrument begins measuring total light ever emitted in the universe

A new instrument made a short jaunt to space on the weekend, as part of a mission to measure the total light ever emitted over the universe’s history. The CIBER-2 project will search for stray stars hiding between galaxies by monitoring the cosmic back… Continue reading New instrument begins measuring total light ever emitted in the universe

1,000-foot multi-rotor floating Windcatchers to power 80,000 homes each

Norway’s Wind Catching Systems (WCS) has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world’s biggest single turbines – while reducing costs enough to be immediately compe… Continue reading 1,000-foot multi-rotor floating Windcatchers to power 80,000 homes each

Blood biomarker detects whether depression is due to neurodegeneration

A test could be used as a rapid screening tool in clinics to determine whether a patient's cognitive problems are due to neurodegeneration.

A new study published in the journal Nature Communications is reporting a single blood-based biomarker can detect the presence of 13 neurodegenerative disorders, from frontotemporal dementia to motor neuron disease. The test cannot specifically distinguish each disorder but instead is proposed as a way to determine whether patients with memory problems are suffering from the early stages of neurodegenerative disease.

Purpose-built eVTOL battery promises 50-mile trips on a 10-minute charge

Lithium-ion batteries do a great job of powering smartphones, laptops and even cars, but electric flight presents some unique challenges for this go-to solution for energy storage. Scientists have now demonstrated a new type of lithium-battery that lev… Continue reading Purpose-built eVTOL battery promises 50-mile trips on a 10-minute charge

First new Alzheimer’s drug in decades receives controversial FDA approval

Approval of a new Alzheimer's drug comes after a FDA advisory panel last year overwhelmingly concluded there is not enough evidence to claim it is effective

A new Alzheimer’s disease treatment has been controversially approved for use in the United States despite an independent Food and Drug Administration (FDA) advisory panel reporting last year the drug’s Phase 3 trial results were inconclusive. The approval marks the first new treatment for Alzheimer’s in almost 20 years.

In the test, Boeing’s MQ-25 T1 aerial tanker drone transferred jet fuel to a US Navy F/A-18 Super Hornet.Continue ReadingCatego… Continue reading In an aviation first, Boeing drone refuels another aircraft in mid-air

Weird “wheel animals” wriggle back to life after 24,000 years frozen

Scientists have managed to revive microscopic animals that had been frozen in the Siberian permafrost for 24,000 years. The Bdelloid rotifers, or “wheel animals” as they’re sometimes called, shook off their long sleep and went right back to moving, eat… Continue reading Weird “wheel animals” wriggle back to life after 24,000 years frozen
