Will climate change outpace species adaptation?
Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.
Woolly mammoths may have shared the landscape with first humans in New England
Woolly mammoths may have walked the landscape at the same time as the earliest humans in what is now New England, according to a Dartmouth study published in Boreas. Through the radiocarbon dating of a rib fragment from the Mount Holly mammoth from Mount Holly, Vt., the researchers learned that this mammoth existed approximately 12,800 years ago. This date may overlap with the arrival of the first...
WOX9: A jack of all trades
Researchers at CSHL used CRISPR, a genome-editing tool, to figure out the hidden roles of a developmental gene called WOX9. It usually induces flower branching in tomatoes and influences embryo growth in a plant related to broccoli. By tweaking the DNA in the gene's nearby promoter region, the researchers found WOX9 could induce flower branching in other species. These types of genetic...
Zinc oxide: key component for the methanol synthesis reaction over copper catalysts
A team of researchers led by scientists from the Interface Science Department of the Fritz Haber Institute have found out that the important industrial process of methanol production can be positively influenced if the copper catalyst used in the reaction comes into contact with zinc oxide.
Shíshálh Nation demands action after burial site reportedly desecrated by logging
Chief Warren Paull of the shíshálh Nation is demanding officials take immediate action to address reported damage at a burial site along Sechelt...
The science behind delaying the 2nd dose of COVID-19 vaccines
Federal government scientists have put their support behind delayed second doses of COVID-19 vaccines — which several provinces were already doing — and ongoing research shows some of the benefits of the adapted...
The physical and mental side effects of Zoom fatigue
Zoom fatigue has become a pandemic side effect for people working from home. It has led to neck, back and shoulder pain, and made workers overly aware of their facial expressions because of constant...
SpaceX: Mars ship prototype explodes after first intact landing
Elon Musk’s last two prototypes reached similarly high altitude, but crash-landed in fireballsSpaceX’s futuristic Starship looked like it aced a touchdown Wednesday, but then exploded on the landing pad with so much force that it was hurled into the air.The failure occurred just minutes after SpaceX declared success. Two previous test flights crash-landed in fireballs. Continue...
SpaceX's Starship SN10 rocket launches, lands, sits there, blows up – video
Elon Musks’s Starship rocket has made its first test launch, flight and intact landing – before suddenly exploding minutes later. After a delay to the initial flight, SN10 lifted off from Boca Chica, Texas, reaching an altitude of 10 kilometres, before descending and landing upright, albeit apparently on fire at its base. Three minutes after touchdown and soon after the SpaceX live stream was...

Starship has finally stuck the landing
On March 3, SpaceX’s Starship pulled off a successful high-altitude flight—its third in a row. Unlike in the first two missions, the spacecraft stuck the landing. Then, as in the last two, the spacecraft blew up.
What happened: At around 5:14 p.m. US Central Time, the 10th Starship prototype (SN10) was launched from SpaceX’s test facility in Boca Chica, Texas, flying about 10 kilometers...
Life discovered deep beneath an Antarctic ice sheet 'shouldn't be there'
Researchers hoping to collect mud samples deep beneath an Antarctic ice sheet were amazed to discover small creatures living in the dark, freezing water.
SpaceX completes another successful launch of massive rocket — accompanied by another explosion after landing
The third test of SpaceX's Starship rocket that CEO Elon Musk hopes will one day ferry humans to Mars, launched from Boca Chica, Texas, on Wednesday, and touched down softly, but exploded shortly...
Vancouver needs help keeping up with its Canada goose problem
The Vancouver Park Board is calling in reinforcements in its battle against Canada geese, asking for the public's help to control the growing population of 3,500...
