New study of endangered pacific pocket mice provides valuable genetic insights

In breeding programs aimed at conserving animals from small or isolated populations, scientists must balance the competing needs of adding genetic diversity and avoiding the introduction of harmful genes. This makes for a delicate task of boosting diversity in the endangered Pacific pocket mouse, the focus of a long-running conservation breeding program undertaken by San Diego Zoo Global. There...

First impressions can sway financial professionals' forecasts of firms for up to 6 years

First impressions can have long-term effects on people's perceptions and behavior. A new study looked at the influence among finance professionals of first impression bias of firms' performance, which spurs people to place undue weight on early experiences. The study found that equity analysts placed greater emphasis on early impressions than later ones, that negative first impressions had more...

How stimulus dollars are spent will affect emissions for decades

The COVID-19 pandemic and subsequent lockdowns have led to a record crash in emissions. But it will be emission levels during the recovery—in the months and years after the pandemic recedes—that matter most for how global warming plays out, according to a new Nature commentary from researchers at the University of California San Diego.

Roadkill study identifies animals most at risk in Europe

Around 194 million birds and 29 million mammals are thought to be killed each year on European roads, according to a new study that has ranked the most vulnerable species.An international research team used 90 roadkill surveys from 24 European countries to create a new method of estimating both the birds and mammal species killed most often on roads, and the species most vulnerable to being wiped...

New genetic defect linked to ALS

Researchers have identified how certain gene mutations cause amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. The pathway identified by the researchers may also be responsible for a certain form of dementia related to ALS. The finding could offer potential new approaches for treating this devastating condition.

UK coronavirus: PM says Prof Ferguson's claim that delaying lockdown by a week doubled death toll is 'premature' – as it happened

Imperial College academic’s team wrote paper that led to UK government announcing the lockdown; UK records a further 245 coronavirus deaths, taking total to 41,128Earlier UK lockdown ‘could have saved 20,000 lives’‘Support bubble’ plan lets single parents in England combine householdsUK economy likely to suffer worst Covid-19 damage, says OECDCoronavirus global updates – liveBlack...

Researchers mimic nature for fast, colorful 3D printing

Brilliantly colored chameleons, butterflies, opals - and now some 3D-printed materials -- reflect color by using nanoscale structures called photonic crystals. A new study demonstrates how a modified 3D-printing process provides a versatile approach to producing multiple colors from a single ink.

Protest propaganda is riding on the success of pandemic hoaxes

After months spent battling covid-19, the US is now gripped by a different fever. As the video of George Floyd being murdered by Derek Chauvin circulated across social media, the streets around America—and then the world—have filled with protesters. Floyd’s name has become a public symbol of injustice in a spiraling web of interlaced atrocities endured by black people, including Breonna...

Bird figurine is earliest Chinese artwork ever discovered, say experts

‘Refined’ 2cm carving found in Henan dates to palaeolithic period up to 13,000 years agoA tiny figurine of a bird, carved from burnt bone and no bigger than a £1 coin, is the earliest Chinese artwork ever discovered, according to an international team of archaeologists. The carving, less than 2cm in length, has been dated to the palaeolithic period, between 13,800 and 13,000 years ago,...

Passing challenging introductory chemistry course gives biggest boost to underrepresented students

Studies have shown that students from certain backgrounds are less likely than their peers to complete an undergraduate degree in science, technology, engineering or mathematics—or STEM. These groups are low-income students, first-generation college students, female students and students from underrepresented minority backgrounds: Latinx, African American, Native American and Native Hawaiian and...

Intracellular biopsy technique for fast microRNAs profiling in living cells

MicroRNAs (miRNAs) are gaining more attention in studies of human diseases such as cancer, because changes in miRNA expression are frequently associated with abnormal cellular functions. To achieve fast and highly sensitive profiling of miRNAs, a research team from City University of Hong Kong (CityU) has developed a novel intracellular biopsy technique that isolates targeted miRNAs from living...

Molecular twist makes one catalyst useful for three hydrogen applications

Scientists from Kyushu University and Kumamoto University in Japan have developed a new catalyst capable of assisting three key reactions for using hydrogen in energy and industry. Inspired by three types of enzymes in nature, this research can help elucidate unknown relationships among catalysts, paving the way for efficient use of hydrogen gas as a next-generation energy source in the future.

Research team achieves massive sexual conversion of the malaria parasite in a dish

A research team at ISGlobal, an institution supported by the "la Caixa" Foundation, has developed a system to induce massive sexual conversion of the P. falciparum malaria parasite in vitro. This technique, published in Science Advances, will prove instrumental to gain a deeper understanding of the sexual conversion process and design new tools to block malaria transmission.
