As rising floodwaters assault Venice, there's now an 85% chance that 2019 will come in as second warmest year

Two U.S. agencies have now released their global warming report cards for last month, and they both show the same depressing grade:
Of the 139 Octobers since 1880, last month was the second warmest on record.

Subsurface water on Jupiter's moon Europa is one place where humans plan to search for life. This artist's concept shows a massive plume of underground water erupting from the moon's surface. (Credit: NASA/ESA/K. Retherford/SWRI)
Jupiter’s moon Europa has an icy shell that conceals a liquid water ocean. Now, scientists have made the first direct measurement of water vapor in Europa’s atmosphere. It's the best evidence yet for a water plume erupting from the moon’s surface.

A new study takes a look at the rates of extramarital childbirth in Europe over the past 500 years. This includes children born as the result of adultery — and, spoiler, it's much lower than you probably think.
The study, published in Current Biology, used genetic and historical data to estimate how often parents had children outside their primary relationship over the past 500 years in Belgium, the Netherlands and Luxembourg. The researc ...read more
Thick palls of smoke stream from Australia's sprawling bushfires in this view acquired by NASA's Aqua satellite on Nov. 11, 2019. The image consists of a natural-color view with an infrared overlay revealing areas of burning. (Source: NASA Worldview image processed by Pierre Markuse)
So far, Australia's bushfires have scorched more than 4,000 square miles — an area greater than ten times the size of New York City.
With hot and dry conditions predicted for weeks to come, there's not ...read more
Many people may be living life without a particular brain region - and not suffering any ill-effects.
In a new paper in Neuron, neuroscientists Tali Weiss and colleagues discuss five women who appear to completely lack olfactory bulbs (OB).
According to most neuroscience textbooks, no OB should mean no sense of smell, because the OB is believed to be a key relay point for olfactory signals. As Wikipedia puts it:
The olfactory bulb transmits smell information from the nose to the b ...read more

When the LIGO collaboration first detected the spacetime ripples of a gravitational wave it came from the merger of two black holes. To date, scientists have detected at least ten pairs of black holes spiraling into and combining with each other.
But there's still an outstanding mystery about these singularities: why are some of them so big? Some have been far larger than scientists think po ...read more

In late August, an instrument on the International Space Station, called NICER, spotted its brightest burst of X-ray radiation yet.
NICER, or the Neutron Star Interior Composition Explorer, studies X-rays that come from neutron stars, the super-dense remnants of some stars afte ...read more

It was a typical Japanese summer — hot, humid and cloudy — when archaeologists pulled a well-preserved, fossilized bird from the ground in 2013. Their find, announced this week in Nature Communications Biology, might change our idea of what adaptations were essential to the development of flight.

Named Fukuipteryx prima, the archaeologists date the bird ...read more
